FORMULAS
TC = TCb x Ct x EtSC = SCb x Cs x Es
Where: Cs = Sensible Air Flow Correction Factor Ct = Total Air Flow Correction Factor Es = Sensible Elevation Correction Factor Et = Total Elevation Correction Factor SC = Sensible Capacity SCb = Base Sensible Capacity from Base Cooling Capacities by GPM charts TC = Total Capacity TCb = Base Total Capacity from Base Cooling Capacities by GPM charts
QUICK SELECTION
EXAMPLE
To rate the performance at sea level for a CHY-04 unit with three-row coil at 80/67 EAT, 45 EWT and 2 GPM water ow at high speed fan with 0.15 inches ESP: (1) Select the 80/67 EAT from the Base Cooling Capacities table on page 8.
(2) Locate the appropriate table for size 04 with three-row coil and 2 GPM.
Record the tabulated base performance.
TCb = 10.5 MBH SCb = 8.3 MBH
(3) Select the actual CFM from the Air Delivery table on page 12.
Record actual CFM for CHY-04 with three-row coil with high speed and 0.15 ESP.
CFM Actual = 415
(4) Divide CFM Actual by CFM Nominal to determine CFM Ratio.
CFM Ratio = 415/400 = 1.0375
(5) Select the CFM correction factors, Ct and Cs, from the Air Flow Correction Factors table on page 13.
Ct = 1.03 Cs = 1.03
(6) Select the elevation correction factors, Et and Es, from the Elevation Correction Factors table on page 13.
Et = 1.00 Es = 1.00
(7) Calculate actual performance.
TC = TCb x Ct x Et = 10.5 x 1.03 x 1.00 = 10.8 MBH SC = SCb x Cs x Es = 8.3 x 1.03 x 1.00 = 8.5 MBH
(8) Calculate water pressure drop (or refer to the Water Presure Drop for Cv Factor and Water Flow Rate table on page 15). From the Cv Factor by Unit Size table on page 14, nd the Cv value for the unit size 04 with three rows.
Cv = 0.9 P = [GPM/(0.658 x Cv)]2 = [2.0/(0.658 x .9)]2
= 11.4 feet of H2O

HYDRONIC COIL PRESSURE DROP
All IEC hydronic coils have a coefcient of velocity (Cv) resistance factor assigned to assist in a more accurate determination of water pressure drop (see Cv Factor by Coil and Unit Size table below).
CALCULATING PRESSURE DROP
The Cv factor is equal to the ow rate of water in GPM through a piping component when the pressure drop through the component is 1.0 pounds per square inch (psi), or 2.31 feet of H
2O.
P (feet of H2O) = P (PSI) x 2.31
Use the Cv factor from the Cv Factor by Coil and Unit Size table below to determine the water coil pressure drop.
Coil pressure drop (feet of H2O):
P = (GPM2/Cv2) x 2.31or P = [GPM/(0.658 x Cv)]2
or Refer to the Water Pressure Drop for Cv Factor and Water Flow Rate table on page 15.
EXAMPLE
Model CPY 06 BYY requires 3.0 GPM water ow. Determine the water coil pressure drop as follows.
Unit size = 06, Coil type = B, GPM = 3.0Cv from Cv Factor by Coil and Unit Size table below = 2.0
P = (3.02/2.02) x 2.31 = 5.2 feet of H

Electric heaters are available on IEC Horizontal Series fan coil units for the following applications.
TOTAL ELECTRIC HEAT
Total electric heat eliminates the requirement for a boiler. Heating and/or cooling may be available on an individual basis throughout the year. Two-pipe chilled water is used for cooling; and the electric heater is used for heating. Individual room controls can be supplied for either manual or automatic changeover.
AUXILIARY ELECTRIC HEAT
Auxiliary electric heat is ideal for tempering room air between seasons and during the cooling season when chilled water is being circulated. Individual room controls are supplied to provide electric heat only when chilled water is being circulated. During regular heating season, heating is provided by hot water being circulated in the system.
CONSTRUCTION
The heater coils of high-grade resistance wire are supported by ceramic insulators on plated steel brackets. These heat elements are suspended directly in front of the fan outlet between the blower and the coil. High limit thermal cutouts protect the heater in the event of air failure. There are many special applications and control sequences for electric heat. For special applications, please consult the factory.

MECHANICAL SPECIFICATIONS
PERFORMANCE DATA (ALL MODELS)
CAPACITIESUnit capacities are certied in compliance with Air Conditioning and Refrigeration Institute (ARI) Industry Standard 440-98.
SAFETYUnits are listed with Underwriters Laboratories, Inc. (UL) Standard UL 1995 and with Canadian Standards Association (CSA) Standard C22.2 No. 236.
BASIC UNIT
The basic unit (models CH and BH) is fabricated of galvanized steel. Horizontal models CP and BP are provided with galvanized-steel plenums for lter mounting and return-duct attachment. One-half inch, glass-ber, thermal insulation is provided, where applicable. Provision for hanging the unit using ceiling hanger rods is provided by slots and/or holes in the top of the housing. A one-inch, discharge-duct collar is furnished. The motor-blower assembly is designed to facilitate servicing.
The condensate drain pan is lined with closed-cell, re-retardant, foam insulation. Water does not contact the metal pan, minimizing the possibility of corrosion. All Horizontal units (models CH, BH, CP, BP, CB and CX) are available with an optional drip lip at the coil-header end to provide positive control of condensate from control valve components.
CABINETS
Horizontal cabinet models CX and CB are constructed of galvanized-steel panels, thermally insulated and provided standard with a powder-coat paint nish. Optional color selections are available. Mounting holes are provided. Horizontal models CX and CB have a hinged bottom panel for access to coil, valve-package, control-package, motor-blower and electric-heater sections. Stamped supply and return grilles are standard. Double-deection, supply grilles are optional.
COILS
Coils are constructed with one-half inch copper tubes with aluminum ns mechanically bonded to the tubes. All coils are leak tested with air under water and are suitable for design working pressures of 250 psig at 200F. A variety of coil selections is available. The standard coil provides adequate capacity for most installations with an eight-to-ten degree water-temperature rise design. A high capacity coil is offered for those installations requiring the higher latent heat capacities or those designed for higher water temperature rises. Also offered is a four-pipe coil consisting of standard- or high-capacity cooling with one or two rows of heating surfaces contained in a single n bank.
OTHER UNIT OPTIONS
Stainless steel drain pans Optional insulations
FANS
The fans are centrifugal, forward-curved, double-width wheels. Blower housings are galvanized steel with special-rolled perimeter seams to provide added rigidity.
MOTORS
All motors are UL-listed, resilient-mounted, three-speed, permanent-split-capacitor (PSC) type with thermal-overload protection. Motor bearings are of the permanently-lubricated sleeve type. Positive speed reduction is assured through matching of motor torque to blower loading.
