Step 2 — Plan for Sequence of Unit InstallationThe support method used for this unit will dictate differentsequences for the steps of unit installation. For example, oncurb−mounted units, some accessories must be installed onthe unit before the unit is placed on the curb. Review thefollowing for recommended sequences for installation steps.Curb−mounted installation —

Install roof curbInstall field−fabricated ductwork inside curbInstall accessory thru−base service connection package, ifused, (affects curb and unit) (refer to accessoryinstallation instructions for details)Prepare condensate drain connection to suit plannedcondensate line routing (refer to Step 9 for details)Rig and place unit

Install outdoor air hoodInstall condensate line trap and pipingMake electrical connectionsInstall other accessories

Pad−mounted installation —Prepare pad and unit supportsCheck and tighten the bottom condensate drainconnection plugRig and place unitInstall outdoor air hoodConvert unit to side duct connection arrangementInstall field−fabricated ductwork at unit duct openingsInstall condensate line trap and pipingMake electrical connections


Install other accessoriesFrame−mounted installation —

Frame−mounted applications generally follow thesequence for a curb installation. Adapt as required to suitspecific installation plan.

Step 3 — Inspect unitInspect unit for transportation damage. File any claim withtransportation agency.Confirm before installation of unit that voltage, amperageand circuit protection requirements listed on unit data plateagree with power supply provided.

Step 4 — Provide Unit SupportRoof Curb Mount —Accessory roof curb details and dimensions are shown inFig. 4. Assemble and install accessory roof curb inaccordance with instructions shipped with the curb.NOTE:The gasketing of the unit to the roof curb is critical fora watertight seal. Install gasket supplied with the roof curbas shown in Fig. 4. Improperly applied gasket can alsoresult in air leaks and poor unit performance.Curb should be level. This is necessary for unit drain tofunction properly. Unit leveling tolerances are show in Fig. 5.Refer to Accessory Roof Curb Installation Instructions foradditional information as required.

Install insulation, cant strips, roofing felt, and counterflashing as shown. Ductwork must be attached to curb andnot to the unit. The accessory thru−the−base power and gasconnection package must be installed before the unit is seton the roof curb.If electric and control wiring is to be routed through thebasepan, attach the accessory thru−the−base serviceconnections to the basepan in accordance with theaccessory installation instructions.Slab Mount (Horizontal Units Only) —Provide a level concrete slab that extends a minimum of 6in. (150 mm) beyond unit cabinet. Install a gravel apron infront of condenser coil air inlet to prevent grass and foliagefrom obstructing airflow.NOTE:Horizontal units may be installed on a roof curb ifrequired.

Alternate Unit Support (In Lieu of Curb or Slab Mount)—A non−combustible sleeper rail can be used in the unit curbsupport area. If sleeper rails cannot be used, support thelong sides of the unit with a minimum of 3 equally spaced4−in. x 4−in. (102 mm x 102 mm) pads on each side.

Observe national and localcodes when selecting wire size, fuse or breakerrequirements and disconnect switch size and location.Route 125−v power supply conductors into the bottom of theutility box containing the duplex receptacle.

FIGURE 19 Thru−Base Connection Fittings

Optional Thru−Base Connections —

This accessory (field installed) service connection kitconsists of a 1−1/4−in and a 1/2−in electrical bulkheadconnector, all must be installed in the embossed (raised)section of the unit basepan in the condenser section. The1/2−in bulkhead connector enables the low−voltage controlwires to pass through the basepan. The 1−1/4−in electricalbulkhead connector allows the high−voltage power wires topass through the basepan. See Fig. 19.

Note: This must be installed prior to mounting unit onroof curb.

Check tightness of connector lock nuts before connectingelectrical conduits.

Field−supplied and field−installed liquid tight conduitconnectors and conduit may be attached to the connectorson the basepan. Pull correctly rated high voltage and lowvoltage through appropriate conduits. Connect the powerconduit to the internal disconnect (if unit is so equipped) orto the external disconnect (through unit side panel). A holemust be field cut in the main control box bottom on the leftside so the 24−v control connections can be made. Connectthe control power conduit to the unit control box at this hole.

Units without Thru−Base Connections —

1. Install power wiring conduit through side panelopenings. Install conduit between disconnect andcontrol box.

2. Install power lines to terminal connections.

Voltage to compressor terminals during operation must bewithin voltage range indicated on unit nameplate. See Table3. On 3−phase units, voltages between phases must bebalanced within 2% and the current within 10%. Use theformula shown in the legend for Table 3, Note 2 todetermine the percent of voltage imbalance. Operation onimproper line voltage or excessive phase imbalanceconstitutes abuse and may cause damage to electricalcomponents. Such operation would invalidate any applicablewarranty.

Field Control Wiring —

The RAS unit requires an external temperature controldevice. This device typically applied with a commercialthermostat (field−supplied) with both occupied andunoccupied setpoints at a minimum.

Thermostat —

Install an approved accessory commercial thermostataccording to installation instructions included with theaccessory. For complete economizer function, select atwo−stage cooling thermostat. Locate the thermostataccessory on a solid wall in the conditioned space to senseaverage temperature in accordance with the thermostatinstallation instructions.

If the thermostat contains a logic circuit requiring 24−vpower, use a thermostat cable or equivalent single leads ofdifferent colors with minimum of seven leads. If thethermostat does not require a 24−v source (no “C”connection required), use a thermostat cable or equivalentwith minimum of six leads. Check the thermostat installationinstructions for additional features which might requireadditional conductors in the cable.

For wire runs up to 50 ft. (15 m), use no. 18 AWG (AmericanWire Gage) insulated wire (35�C minimum). For 50 to 75 ft.(15 to 23 m), use no. 16 AWG insulated wire (35�C


minimum). For over 75 ft. (23 m), use no. 14 AWG insulatedwire (35�C minimum). All wire sizes larger than no. 18 AWGcannot be directly connected to the thermostat and willrequire a junction box and splice at the thermostat.

Unit without thru−base connection kit —

Pass the thermostat control wires through the hole providedin the corner post; then feed the wires through the racewaybuilt into the corner post to the control box. Pull the wiresover to the terminal strip on the upper−left corner of theControls Connection Board. See Fig. 20 and 21.

SMOKE DETECTORSSmoke detectors are available as factory−installed optionson RAS models. Smoke detectors may be specified forSupply Air only without or with economizer. All componentsnecessary for operation are factory−provided and mounted.The unit is factory−configured for immediate smoke detectorshutdown operation; additional wiring or modifications to unitterminal board may be necessary to complete the unit andsmoke detector configuration to meet project requirements.

SystemThe smoke detector system consists of a four−wirecontroller and one or two sensors. Its primary function is toshut down the rooftop unit in order to prevent smoke fromcirculating throughout the building. It is not to be used as alife saving device.

ControllerThe controller (see Fig. 27) includes a controller housing, aprinted circuit board, and a clear plastic cover. The controllercan be connected to one or two compatible duct smokesensors. The clear plastic cover is secured to the housingwith a single captive screw for easy access to the wiringterminals. The controller has three LEDs (for Power, Troubleand Alarm) and a manual test/reset button (on the coverface).

SensorThe sensor (see Fig. 28) includes a plastic housing, aprinted circuit board, a clear plastic cover, a sampling tubeinlet and an exhaust tube. The sampling tube (when used)

and exhaust tube are attached during installation. Thesampling tube is shipped in the blower section and is wiretied to the blower housing. See Fig. 29. The clear plasticcover permits visual inspections without having todisassemble the sensor. The cover attaches to the sensorhousing using four captive screws and forms an airtightchamber around the sensing electronics. Each sensorincludes a harness with an RJ45 terminal for connecting tothe controller. Each sensor has four LEDs (for Power,Trouble, Alarm and Dirty) and a manual test/reset button (onthe left−side of the housing).Air is introduced to the duct smoke detector sensor’ssensing chamber through a sampling tube that extends intothe HVAC duct and is directed back into the ventilationsystem through a (shorter) exhaust tube. The difference inair pressure between the two tubes pulls the sampled airthrough the sensing chamber. When a sufficient amount ofsmoke is detected in the sensing chamber, the sensorsignals an alarm state and the controller automatically takesthe appropriate action to shut down fans and blowers,change over air handling systems, notify the fire alarmcontrol panel, etc.The sensor uses a process called differential sensing toprevent gradual environmental changes from triggering falsealarms. A rapid change in environmental conditions, such assmoke from a fire, causes the sensor to signal an alarmstate but dust and debris accumulated over time does not.For installations using two sensors, the duct smoke detectordoes not differentiate which sensor signals an alarm ortrouble condition.

4. In compliance with NEC requirements for multimotor and combinationload equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian unitsmay be fuse or circuit breaker.

5. 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 percentageof voltage imbalance.

% Voltage Imbalance = 100 xmax voltage deviation from average voltage

average voltage

AB = 224 vBC = 231 vAC = 226 v

Average Voltage =(224 + 231 + 226)

=681

3 3

= 227

Determine maximum deviation from average voltage.(AB) 227 – 224 = 3 v Maximum deviation is 4 v.. . . . . . . .(BC) 231 – 227 = 4 v Determine percent of voltage imbalance.. . . . . . . .

% Voltage Imbalance = 100 x4

227

= 1.76%

This amount of phase imbalance is satisfactory as it is below the maximum al-lowable 2%.IMPORTANT: If the supply voltage phase imbalance is more than 2%, contactyour local electric utility company immediately.
