INSTALLATION
1. Remove electric heater modules and single point boxfrom packaging and inspect for damage.NOTE: If there is a “1” in the ninth position of theheater part number, it indicates that the heater is in acarton. For example, CRHEATER105A00 is heaterCRHEATER005A00 in a carton.
2. Remove indoor and outdoor access panels. See Fig. 1and 2. Save panels and screws.
3. Remove control box cover and center post. Savescrews. See Fig. 3.
4. Remove the single point box cover. Secure single pointbox to the underside of the control box with the 2screws provided (Fig. 4).
5. Secure the conduit drip boot bracket assembly to theback of the single point box with 2 of the screws pro-vided (Fig. 4). The channel portion of the bracketassembly extends to the top panel behind the controlbox. Secure all wires to bracket with field-suppliedwire tie as shown in Fig. 5.NOTE: The conduit drip boot and bracket are not usedon standard efficiency 3 to 6 ton electric cooling units.
6. Remove heater cover(s) from heater mounting bracket.Save screws. Install single module electric heat optionin location 1 (nearest the single point box). See Fig. 3and 6.NOTE: Modules CRHEATER105A00, CRHEATER109A00, CRHEATER112A00, CRHEATER114A00,CRHEATER115A00, and CRHEATER119A00 arekeyed and must be installed in location 1 even when usedas part of a 2-module option (Fig. 7).
Turn off power to unit and install lockout tag.

7. To install module, engage flange on heater with trackin unit and slide heater through mounting bracketopening. Fasten heater module to heater mountingbracket with the 4 screws saved from Step 6 (Fig. 4).NOTE: All 208/230-v heaters (except CRHEATER105A00) are factory-wired for 3-phase applicationsbut can be converted to single-phase by changing onewire as described in Step 8.Three-phase applications: Skip to Step 9.
8. On single-phase applications, rewire the heater as fol-lows (see Fig. 8-10):a. Connect 10-gage red wire to splice connector.b. Remove yellow wire from heater contactor terminal
11 and connect to splice connector.c. Using the wire tie provided, fasten red wire to heater
power wire harness near existing wire tie on heatermodule. This provides strain relief for the red wire.
9. Route power wires from heater module(s) through thefoam bushing in the center partition and into the singlepoint box (Fig. 4). If no single point box is required forthe unit and heater combination, run the heater highvoltage power wiring through the grommet holes to thefield-supplied disconnect (or optional factory-supplied80 amp disconnect). Heater control wiring should berun to the control box section.
10. Install bushing in hole between control box and singlepoint box. Route unit power pigtails through bushing(Fig. 4).
11. See Table 1 to determine the correct electrical datatable. Refer to Electrical Data Tables 2-25 todetermine the heater and single point box. From theElectrical table determine the MOCP with heatersand accessories, the number of heaters, and theCRSINGLE---A00 part number.The correct figure can be determined using Table 1.The unit type (cooling only, heat pump, or COBRA™combined unit), efficiency type (high, standardASHRAE 90.1 compliant, standard), and the unitvoltage are listed in Table 1. If more than one figure is
shown in Table 1, then there are different figures forunits based on an MOCP below or above 60 Amps.Use the correct figure based on the MOCP determinedfrom the correct electrical data table. Figures 11-15 arefor electric cooling units. Figures 16-20 are for heatpump units. Figures 21-28 are for COBRA combinedrooftop/energy recovery units.All fuses are 60 amp, time delay type, except forCRSINGLE025A00 which are 30 amps. All heatersare single bank heaters except CRHEATER011A00and 012A00 which are dual bank heaters. TheCRHEATER011A00 and 012A00 will be wired as twoheaters (i.e., 6 leads). Fusing is shown pictorially. Thesingle point box fuse location may not EXACTLYmatch the figure as shown, but the number of fuseswill match the number shown.The optional factory-supplied disconnect has amaximum rating of 80 amps. Above 80 amps a field-supplied disconnect is required.Single point boxes CRSINGLE001A00, 006A00 and011A00 do not include fuses and fuses are not requiredper the National Electric Code in these single pointboxes since sub-fusing is not required below 60 amps.Field-supplied pressure connectors are required toconnect wires.
12. Run control wires from heater module(s) to the controlwire terminal block located next to the heater mod-ule(s). Connect the control wires as shown in Fig. 29.Heat Pump UnitsThe electric heat is internally wired as the second stageof heat.Electric Cooling UnitsElectric cooling units with 2 electric heater modulescan be wired for one- or 2-stage options as shown inFig. 29. Connect single module heater option controlwire (violet) to TB4 terminal 1.
13. Replace the center post and secure the single point boxto the center post with one screw (Fig. 3).

*Used to determine minimum disconnect per NEC.†Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v. Ifpower distribution voltage to unit varies from rated heater voltage, heater kW willvary accordingly.
NOTES:1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective devicefor the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greaterthan 2%. Use the following formula to determine the percent of voltageimbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance= 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximumallowable 2%.
3. Non-fused disconnect switch cannot be used when rooftop unit electrical ratingsexceed 80 amps.
4. 575-v units have UL, Canada approval only. Electric heaters are not available for3 to 6 ton, 575-v units.

*Used to determine minimum disconnect per NEC.†Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v. If
power distribution voltage to unit varies from rated heater voltage, heater kW will varyaccordingly.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shallbe fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%.Use the following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.
3. Non-fused disconnect switch cannot be used when rooftop unit electrical ratingsexceed 80 amps.
4. 575-v units have UL, Canada approval only. Electric heaters are not available for 3 to6 ton, 575-v units.

NOTES:1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer to
NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACRbreaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use thefollowing formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is poweredthrough the unit (must be in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-able. If “MCA New” is larger than the published MOCP, raise the MOCP to the next largersize. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.
NOTES:1. In compliance with NEC requirements for multimotor and combination
load equipment (refer to NEC Articles 430 and 440), the overcurrentprotective device for the unit shall be fuse or HACR breaker. Canadianunits may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage isgreater than 2%. Use the following formula to determine the percentof voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below themaximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used,size wire to include power exhaust MCA and MOCP. Check MCAand MOCP when power exhaust is powered through the unit (mustbe in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35,with CRPWREXH030A00 power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCPwould not change. The MOCP in this example is 35 amps, the MCANew is below 35, therefore the MOCP is acceptable. If “MCA New”is larger than the published MOCP, raise the MOCP to the nextlarger size. For separate power, the MOCP for the power exhaustwill be 15 amps per NEC.

2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use thefollowing formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is poweredthrough the unit (must be in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-able. If “MCA New” is larger than the published MOCP, raise the MOCP to the next largersize. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer to
NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACRbreaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use thefollowing formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is poweredthrough the unit (must be in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change.

*Two heater packages required to provide kW indicated.†004 on units with convenience outlet.**002 on high-static units.
NOTES:1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2
kWnew = 12.8 kW (rating at 215 v)

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer to
NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACRbreaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use thefollowing formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is poweredthrough the unit (must be in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-able. If “MCA New” is larger than the published MOCP, raise the MOCP to the next largersize. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer to
NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACRbreaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the fol-lowing formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to include powerexhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through theunit (must be in accordance with NEC and/or local codes). Determine the new MCA includingthe power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 71/2 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-able. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size.For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer to
NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACRbreaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Use thefollowing formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is poweredthrough the unit (must be in accordance with NEC and/or local codes). Determine the newMCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is accept-able. If “MCA New” is larger than the published MOCP, raise the MOCP to the next largersize. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

*Used to determine minimum disconnect per NEC.†Fuse or HACR circuit breaker.**Fuse only.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shallbe fuse or HACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%.Use the following formula to determine the percent of voltage imbalance.
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.
3. For units with power exhaust: If a single power source is to be used, size wire toinclude power exhaust MCA and MOCP. Check MCA and MOCP when powerexhaust is powered through the unit (must be in accordance with NEC and/or localcodes). Determine the new MCA including the power exhaust using the following for-mula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 71/2 ton unit with MCA = 28.9 and MOCP = 35, withCRPWREXH030A00 power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would notchange. The MOCP in this example is 35 amps, the MCA New is below 35, thereforethe MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise theMOCP to the next larger size. For separate power, the MOCP for the power exhaustwill be 15 amps per NEC.

NOTES:1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v. If power distri-bution voltage to unit varies from rated heater voltage, heater kW will vary accordingly.
†Heaters are field installed only.**Fuse or HACR circuit breaker.
††Electrical disconnect cannot be used if electric heater is installed.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equip-
ment (refer to NEC Articles 430 and 440), the overcurrent protective device for theunit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than2%. Use the following formula to determine the percentage of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v. If power distri-bution voltage to unit varies from rated heater voltage, heater kW will vary accordingly.
†Heaters are field installed only.**Fuse or HACR circuit breaker.
††Electrical disconnect cannot be used if electric heater is installed.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equip-
ment (refer to NEC Articles 430 and 440), the overcurrent protective device for theunit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than2%. Use the following formula to determine the percentage of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.

Table 14 — Electric Heater Usage — High-Efficiency Heat Pump Units
*Two heater packages required to provide kW indicated.NOTES:
1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2
kWnew = 12.8 kW (rating at 215 v)

*Heaters are field installed only.†Used to determine minimum disconnect size per NEC.**Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v. If power dis-
tribution voltage to unit varies from rated heater voltage, heater kW will vary accord-ingly.
††Fuse or HACR circuit breaker.***Optional disconnect switch is unavailable.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shallbe fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%.Use the following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.

*Heaters are field installed only.†Used to determine minimum disconnect size per NEC.**Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v.
If power distribution voltage to unit varies from rated heater voltage, heaterkW will vary accordingly.
††Fuse or HACR circuit breaker.***Optional disconnect switch is unavailable.
NOTES:1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protectivedevice for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage isgreater than 2%. Use the following formula to determine the percent of volt-age imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximumallowable 2%.

Table 17 — Electric Heater Usage — Standard-Efficiency Heat Pump Units
*Two heater packages required to provide kW indicated.†Use CRSINGLE004A00 for units with convenience outlet.**Use CRSINGLE005A00 for units with convenience outlet.
††Use CRSINGLE002A00 for units with convenience outlet.***Use CRSINGLE002A00 for units with high-static motor and convenience outlet.
†††Use CRSINGLE008A00 for units with an electrical convenience outlet.NOTES:1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW new = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkW new = 16 kW (215/240)2
kW new = 12.8 kW (rating at 215 v)

*Used to determine minimum disconnect per NEC.
NOTES:1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective devicefor the unit shall be fuse or HACR breaker. UL, Canada units may be fuse or cir-cuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greaterthan 2%. Use the following formula to determine the percent of voltageimbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allow-able 2%.

As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2
kWnew = 12.8 kW (rating at 215 v)

NOTES:1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective devicefor the unit shall be fuse or HACR breaker. UL, Canada units may be fuse or cir-cuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greaterthan 2%. Use the following formula to determine the percent of voltageimbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x

*Two heater packages required to provide kW indicated.†002 on units with convenience outlet.
**003 on high-static units with convenience outlet.††004 on units with convenience outlet.
NOTES:1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2
As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkWnew = 16 kW (215/240)2
kWnew = 12.8 kW (rating at 215 v)

*Used to determine minimum disconnect per NEC.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shallbe fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%.Use the following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW new = Heater kW rated x (unit power distribution voltage / rated heater voltage) 2As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkW new = 16 kW (215/240) 2kW new = 12.8 kW (rating at 215 v)

*Used to determine minimum disconnect per NEC.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shallbe fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%.Use the following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
= 457
Determine maximum deviation from average voltage.(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.

**Single point box is part of base unit.NOTES:
1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW vary accordingly.2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW new = Heater kW rated x (unit power distribution voltage / rated heater voltage) 2As an example:For a 16 kW heater rated at 240 v with a power distribution voltage of 215 vkW new = 16 kW (215/240) 2kW new = 12.8 kW (rating at 215 v)
