reverse cycle air conditioners designed for outdoor installa-

tion on a rooftop or slab and for non-residential use. These

units can be equipped with factory or field installed electric

heaters for heating applications.

These units are completely assembled on rigid, permanently

attached base rails. All piping, refrigerant charge, and electri-

cal wiring is factory installed and tested. The units require

electric power and duct connections. The electric heaters

have nickel-chrome elements and utilize single-point power

connection.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any

packaging until the unit is near the place of installation. Rig

the unit by attaching chain or cable slings to the lifting holes

provided in the base rails. Spreader bars, whose length

exceeds the largest dimension across the unit, MUST be

used across the top of the unit.

Units may be moved or lifted with a forklift. Slotted openings

in the base rails are provided for this purpose.

LENGTH OF FORKS MUST BE A MINIMUM OF 60 INCHES

(1524 mm).

If a unit is to be installed on a roof curb other than a

YORK roof curb, gasketing must be applied to all

surfaces that come in contact with the unit under-

side.

Before lifting, make sure the unit weight is distrib-

uted equally on the rigging cables so it will lift evenly.

All panels must be secured in place when the unit is

lifted.

The condenser coils should be protected from rig-

ging cable damage with plywood or other suitable

material.

DUCTWORK

Ductwork should be designed and sized according to the

methods in Manual D of the Air Conditioning Contractors of

America (ACCA) or as recommended by any other recog-

nized authority such as ASHRAE or SMACNA.

A closed return duct system should be used. This will not

preclude use of economizers or outdoor fresh air intake. The

supply and return air duct connections at the unit should be

made with flexible joints to minimize noise.

The supply and return air duct systems should be designed

for the CFM and static pressure requirements of the job. They

should NOT be sized to match the dimensions of the duct

connections on the unit.

Refer to Figure 9 for bottom air duct openings. Refer to Fig-

ure 10 for rear air duct openings.

DUCT COVERS

Units are shipped with the side duct openings covered and a

covering over the bottom of the unit. For bottom duct applica-

tion, no duct cover changes are necessary. For side duct

application, remove the side duct covers and install over the

bottom duct openings. The panels removed from the side

duct connections are designed to be reused by securing each

panel to its respective downflow opening. But keep in mind

that the supply panel is installed with the painted surface UP,

facing the heat exchanger, while the return panel is installed

with the painted surface DOWN, facing the downflow duct

opening. The supply panel is secured with the bracket

(already in place from the factory) and two screws. It’s a snug

fit for the panel when sliding it between the heat exchanger

and unit bottom, but there is room. The return panel is

secured with four screws.

CONDENSATE DRAIN

The side condensate drain is reversible and maybe re-ori-

ented to the rear of the cabinet to facilitate condensate pip-

ing. A condensate drain connection is available through the

base pan for piping inside the roof curb. Trap the connection

per Figure 16. The trap and drain lines should be protected

from freezing.

Plumbing must conform to local codes. Use a sealing com-

pound on male pipe threads. Install condensate drain line

from the 3/4 inch NPT female connection on the unit to an

open drain.

COMPRESSORS

The compressors are mounted on elastomer insulators. The

mounting bolts have been fully tightened for shipping.

FILTERS

Two-inch filters are supplied with each unit. One-inch filters

may be used with no modification to the filter racks. Filters

must always be installed ahead of evaporator coil and must

be kept clean or replaced with same size and type. Dirty fil-

ters reduce the capacity of the unit and result in frosted coils

or safety shutdown. All units use four (4) 20”x25”x2” filters.

The unit should not be operated without filters properly

installed.

THERMOSTAT WIRING

The thermostat should be located on an inside wall approxi-

mately 56 inches above the floor where it will not be subject

to drafts, sun exposure or heat from electrical fixtures or

appliances. Follow the manufacturer's instructions enclosed

with thermostat for general installation procedure. Seven (7)

color-coded, insulated wires should be used to connect the

thermostat to the unit. Refer to Table 7 for control wire sizing

and maximum length.

POWER AND CONTROL WIRING

Field wiring to the unit, fuses, and disconnects must conform

to provisions of National Electrical Code (NEC), ANSI/NFPA

No. 70 – Latest Edition (in U.S.A.), current Canadian Electri-

cal Code CSA C22.1, and/or local ordinances. The unit must

be electrically grounded in accordance with NEC and CEC as

specified above and/or local codes.

Voltage tolerances which must be maintained at the com-

pressor terminals during starting and running conditions are

indicated on the unit Rating Plate and Table 2.

The internal wiring harnesses furnished with this unit are an

integral part of the design certified unit. Field alteration to

comply with electrical codes should not be required. If any of

the wire supplied with the unit must be replaced, replacement

wire must be of the type shown on the wiring diagram and the

same minimum gauge as the replaced wire.

A disconnect must be utilized for these units. When installing

a disconnect, refer to Figure 4 for the recommended mount-

ing location.

NOTE: Since not all local codes allow the mounting of a dis-

connect on the unit, please confirm compliance with

local code before mounting a disconnect on the unit.

Electrical line must be sized properly to carry the load. USE

COPPER CONDUCTORS ONLY. Each unit must be wired

with a separate branch circuit fed directly from the meter

panel and properly fused.

Refer to Figures 17, 18 and 19 for typical field wiring and to

the appropriate unit wiring diagram mounted inside control

doors for control circuit and power wiring information.

POWER WIRING DETAIL

Units are factory wired for the voltage shown on the unit

nameplate. Refer to Electrical Data Tables 8 and 9 to size

power wiring, fuses, and disconnect switch.

Power wiring is brought into the unit through the side of the

unit or the basepan inside the curb.

NOTE: This unit does not require a heat pump thermostat.

It is designed to work with a standard two-stage

cool, two-stage heat thermostat; however, the ther-

mostat must provide a “G” signal when there is a

call for “W1”.

Avoid damage to internal components if drilling

holes for disconnect mounting.

When connecting electrical power and control wiring

to the unit, water-proof connectors must be used so

that water or moisture cannot be drawn into the unit

during normal operation. The above water-proofing

conditions will also apply when installing a field sup-

plied disconnect switch.
