CHX/CVX SeriesHeat Pump / DX *Air Handling Units

2 THROUGH 20 TONS

Westair commercial-duty CHX/CVX heat pump/DX units are designed for installation within the conditioned areaor as remote units with duct systems. These blower coil units are compact, with large removable panels forease of installation and service. All 2 - 5 ton models feature piston-type metering devices and are approved foreither straight cool or heat pump operation. All 7 1/2 - 20 ton models have factory installed expansion valvesand are approved for straight cool only (not heat pump) operation. All 7 1/2 ton models have single circuit coilswhile all 10 - 20 ton models have dual-circuited coils. Separate filter access panels are provided on both sidesof unit. Optional accessories include hot water coils, expansion valves for 2-5 ton models, various motoroptions, mixing boxes, and discharge plenums.Standard models are available in 8 popular sizes - 800 through 8000 nominal CFM (2 through 20 tons). Allstandard models are ETL listed and are rated in accordance with ARI Standard 430.

Standard FeaturesCABINET -Fabricated of heavy gauge galvanized steel. Seismic resistantmounting brackets are standard on all models.

BLOWER -Resiliently mounted, heavy duty, double inlet, forward curved blade,centrifugal type. Each wheel is dynamically balanced for smooth,quiet operation. All blowers are belt driven with field adjustablepulleys to permit variations in static pressure and air requirements.All blowers have ball bearings.

COILS -Fabricated of 3/8" or 1/2" OD seamless copper tubes mechanicallyexpanded to highly efficient aluminum fins to maximize heat transfer.All 2 - 5 ton models feature piston-type metering devices approvedfor either straight cool or heat pump operation. All 7 1/2 - 20 tonmodels have factory installed expansion valves approved for straightcool only (not heat pump) operation. All 7 1/2 ton models havesingle circuit coils while all 10 - 20 ton models have dual-circuitedcoils.

INSULATION -The entire interior of the cabinet is insulated with a special one (1)inch insulation coated with an EPA registered agent which effectivelyresists the growth of bacteria and fungi. This insulation can alsohandle the abuse of maintenance and cleaning practices listed byNAIMA (North American Insulation Manufacturers Association).

FILTER -One inch throw away filters are provided as standard in all 2 - 5ton units. One inch permanent filters are provided as standardin all 7-1/2 - 20 ton units. Filters can be changed withouttools. Space available for 2".

FACTORY WIRED -All standard motors are field or factory installed and wired atvoltage specified by customer. (If not specified, multi-voltagemotors will be wired at highest voltage)

MOTOR -Standard motor is 1725 RPM. The adjustable motor mountpermits easy belt adjustment. A variable pitch pulley allowsbalancing of the system to the desired CFM.

MISCELLANEOUS -- Slotted mounting rails for easy installation (2 -5 ton CHW

only). Rails are turned down 1/2" on each end for safer andeasier installation.

- 4 x 4 junction box accepts a field installed (24/120V) relay /transformer for low voltage control.

- 3/4 inch NPT drain connections on both sides of cabinet.

- Header connections on the right side as standard. Knock-outs are provided for conversion to the left side. (Lookingwith air flow).

- Drain pans are coated for corrosion protection.

Options (Cont.)

Mixing Boxes

Dimensions:

1. Cabinet fully insulated - 3/4 inch.2. Embossed galvanized cabinet on 24-240MB.3. Crank arms and linkage rod for damper connection are furnished. Connections can be made on either side

of mixing boxes. The balance of necessary linkage hardware, damper motor, and controls to be field supplied.4. Dampers can be positioned for either rear/top or rear/bottom locations.5. 1" duct flanges provided on damper openings.6. Dampers have air seals on the edges for positive closing. 24-90MB have single horizontal damper blades.

120-240MB have double horizontal damper blades.7. When used with water coil units, a "freeze stat" must be installed to prevent coil damage caused by low

ambient conditions.

UNIT SELECTION PROCEDURE

1. Complete as much of the “INFORMATION REQUIRED FOR UNIT SELECTION” on page 2 as possible.

Example:

INFORMATION REQUIRED FOR UNIT SELECTION

CFM ___3900___ E.S.P. __.80___ MOTOR: HP:_________VOLTAGE:____230____PHASE:___3___

COOLING: INDOOR: DB ___.80____ WB ____67___ SUCTION TEMP. ____ OUTDOOR: DB___________

TOTAL BTUH____158,000___SENS. BTUH ____________

HEATING: TOTAL BTUH ___________GPM___________EWT___________EAT___________

MISC: ___________

2. Select the unit model that meets the required total MBH cooling and heating at the required conditions fromtables on pages 16 – 23 (capacities and air are the same for CHX and CVX models).

Example: Required clg. capacity = 158,000 BTUH clg.

Unit selected = 120CHX4

3. Refer to pages 7- 9 for the balance of the selection procedure : If the required CFM falls within therange for the selected model, proceed to number 4. If not, use the First Co. Computer Selection Program orcontact the factory for assistance.

4. Determine the required motor horsepower by matching the selected model (i.e. 120CHX4) with the closestCFM at the required External Static Pressure (ESP). Note the horsepower (HP) at the top of the CFM rangethat is needed.

Example: Required CFM is 3900 at .80 ESP.

HP required = 2 HP

5. Select the motor voltage, phase, and horsepower and then the appropriate Motor Drive Assembly Numberthat applies.

Example: Above example requires Motor Drive Assembly Number 984120-G3

Nom. CLG BTU'S (1,000's)

HOT WATER HEATING CAPACITIES

Notes:1) See below for hot water heating correction

factors.2) Optional 2 row hot water coil can be factory

installed in either the reheat (std.) or preheatpositions.

* 70 degree return air

Notes:1) To determine heating capacity at other than 180 deg. E.W.T. and 70 deg. E.A.T. multiply the

selected heating capacity at 180 deg. times the appropriate correction factor from above chart.2) These correction factors may be used on all First Co. published 180 deg. heating capacities.3) When CHX/CVX units are used with hot water coils the leaving air temperature must not

exceed 150 degrees. At high altitude conditions, blower motor may cutout at a lower LAT.Contact factory for information.
