LOCATION

Use the following guidelines to select a suitable loca-

tion for these units.

1. Unit is designed for outdoor installation only.

2. Condenser coils must have an unlimited supply of

air.

3. Where a choice of location is possible, position the

unit on either north or east side of building.

4. For ground level installation, use a level concrete

slab with a minimum thickness of 101 mm (4”). The

length and width should be at least 6 inches

greater than the unit base rails. Do not tie slab to

the building foundation.

5. Roof structures must be able to support the weight

of the unit and its options and/or accessories. Unit

must be installed on a solid level roof curb or

appropriate angle iron frame.

6. Maintain level tolerance to 13 mm (1/2”) maximum

across the entire length or width of the unit.

If a unit is to be installed on a roof curb or special frame

other than a YORK roof curb, gasketing must be

applied to all surfaces that come in contact with the unit

underside.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove

any packaging until the unit is near the place of installa-

tion. 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.

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

openings in the base rails are provided for this pur-

pose. Fork lengths must be a minimum of 1067 mm

(42”).

Remove the nesting brackets from the four corners on

the top of the unit. All screws that are removed when

removing the brackets must be replaced on the unit.

Refer to Tables 4, 5 and 9 for unit weights and to Table

7 for approximate center of gravity.

CLEARANCES

All units require certain clearances for proper operation

and service. Installer must make provisions for ade-

quate ventilation air. Refer to Dimensions and Clear-

ances shown in Figures 7 through 11 and Table 14 for

the clearances required for combustible construction,

servicing, and proper unit operation.

Before lifting a unit, make sure that all panels

are in place and that its weight is distributed

equally on all cables so it will lift evenly.

Do not permit overhanging structures or shrubs

to obstruct outdoor air discharge outlet, com-

bustion air inlet or vent outlets.

DUCTWORK

Ductwork should be designed and sized according to

the methods in Manual Q of the Air Conditioning Con-

tractors of America (ACCA).

A closed return duct system shall be used. This shall

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 supply air flow rate 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 Figures 7 and 10 for information concerning

side and bottom supply and return air duct openings.

CONDENSATE DRAIN

Plumbing must conform to local codes. Use a sealing

compound on male pipe threads. Install a condensate

drain line from the 3/4” NPT female connection on the

unit to an open drain.

NOTE: The condensate drain operates in a negative

pressure in the cabinet. The condensate drain

line MUST be trapped to provide proper drain-

age. See Figure 1.

When fastening ductwork to side duct flanges

on unit, insert screws through duct flanges

only. DO NOT insert screws through casing.

Outdoor ductwork must be insulated and

waterproofed.

THERMOSTAT

The room thermostat should be located on an inside

wall approximately 1422 mm (56”) above the floor

where it will not be subject to drafts, sun exposure or

heat from electrical fixtures or appliances. Follow man-

ufacturer's instructions enclosed with thermostat for

general installation procedure. A minimum of seven

color-coded insulated wires (#18 AWG) should be used

to connect thermostat to unit.

POWER AND CONTROL WIRING

Field wiring to the unit must conform to provisions of

the National Electrical Code, ANSI / NFPA No. 70 (in

U.S.A.), current Canadian Electrical Code C22.1 (in

Canada) and/or local ordinances. The unit must be

electrically grounded in accordance with NEC and CEC

(as specified above) and/or local codes. Voltage toler-

ances, which must be maintained at the compressor

terminals, during starting and running conditions, are

indicated on the unit Rating Plate and the Unit Applica-

tion Data table.

The internal wiring harness furnished with this unit is

an integral part of a CSA design certified unit. Field

alteration to comply with electrical codes should not be

required.

A fused disconnect switch should be field provided for

the unit. The switch must be separate from all other cir-

cuits. Wire entry at knockout openings require conduit

fittings to comply with NEC (in U.S.A.), CEC (in Can-

ada) and/or local codes. Refer to Figure 7, and 11 for

installation location. 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 mini-

mum gauge as the replaced wire.

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 the Typical Field Wiring Figure 3 and to the

appropriate unit wiring diagram for control circuit and

power wiring information.

OPTIONS/ACCESSORIES

The factory-installed heaters are wired for single point

power supply. Power supply need only be brought into

the single point terminal block and thermostat wiring to

the low voltage terminal strip located in the upper por-

tion of the unit control box.

These CSA approved heaters are located within the

central compartment of the unit with the heater ele-

ments extending into the supply air chamber. Refer to

Figure 7 for access panel location.

Fuses are supplied, where required, by the factory.

Some KW sizes require fuses and others do not. Refer

to Table 3 for minimum airflow limitations and to Table

for electrical data.

208/230-3-60 and 380/415-3-50 units control tran-

formers are factory wired for 230v and 415v power

supply respectively. Change tap on transformer for

208-3-60 or 380-3-50 operation.

See unit wiring diagram.

When connecting electrical power and control

wiring to the unit, waterproof type connectors

MUST BE USED so that water or moisture

cannot be drawn into the unit during normal

operation. The above waterproofing conditions

will also apply when installing a field-supplied

disconnect switch.

ECONOMIZER/MOTORIZED DAMPER AND RAIN HOOD

The instruction for the optional economizer/motorized

damper and rain hood can be found in form 035-

07364-000. Use these instructions when field assem-

bling an economizer rain hood onto a unit. The outdoor

and return air dampers, the damper actuator, the

damper linkage, the outdoor and return air divider baf-

fles, and all the control sensors are factory mounted as

part of the “Factory installed” economizer/motorized

damper options.

POWER EXHAUST/BAROMETRIC RELIEF DAMPER AND

RAIN HOOD

The instructions for the power exhaust/barometric relief

damper and rain hood can be found in form 530.18-

N1.10V.

All of the components, including the dampers, hard-

ware, and mounting instructions are shipped in a single

package external from the unit, and must be field

assembled and installed.

Power exhaust is only available as a field installed

accessory.

ECONOMIZER AND POWER EXHAUST DAMPER

SET POINT ADJUSTMENTS AND INFORMATION

Remove the economizer access panel from the unit.

Loosen but do not remove the two panel latches.

Locate the economizer control module, where the fol-

lowing adjustments will be made.

Check that the damper blades move smoothly without

binding; carefully turn the Minimum Position Adjusting

screw (found on the damper control module) fully

clockwise and then set the thermostat indoor fan switch

to the on position and then off, or energize and de-

energize terminals “R” to “G”.

MINIMUM POSITION ADJUSTMENT

With thermostat set to indoor fan on position, or termi-

nals “R” to “G” energized, turn the Minimum Position

Adjusting screw (located on the damper control mod-

ule) counterclockwise until the desired minimum

damper position has been attained.

ENTHALPY SET POINT ADJUSTMENT

The enthalpy set point may now be set by selecting the

desired setpoint shown in the Enthalpy Setpoint Adjust-

ment Figure 4. Adjust as follows:

• For a single enthalpy operation carefully turn the

set point adjusting screw (found on the damper

control module) to the “A”, “B”, “C” or “D” setting

corresponding to the lettered curve of the Enthalpy

Setpoint Adjustment Figure 4.

• For a dual enthalpy operation, carefully turn the set

point adjusting screw fully clockwise past the “D”

setting.

POWER EXHAUST DAMPER SETPOINT (WITH OR WITH-

OUT POWER EXHAUST)

• With no power exhaust option, adjust the Exhaust

Air Adjustment Screw fully clockwise.

• With power exhaust option, each building pressur-

ization requirement will be different. The point at

which the power exhaust comes on is determined

by the economizer damper position (Percent

Open). The Exhaust Air Adjustment Screw should

be set at the Percent Open of the economizer

damper at which the power exhaust is needed. It

can be set from 0 to 100% damper open.

INDOOR AIR QUALITY

Indoor Air quality (indoor sensor input): Terminal AQ

accepts a +2 to +10 Vdc signal with respect to the

(AQ1) terminal. When the signal is below it's setpoint,

the actuator is allowed to modulate normally in accor-

dance with the enthalpy and mixed air sensor inputs.

When the AQ signal exceeds it's setpoint setting and

there is no call for free cooling, the actuator is propor-

tionately modulated from the 2 to 10 Vdc signal, with 2

Vdc corresponding to full closed and 10 Vdc corre-

sponding to full open. When there is no call for free

cooling, the damper position is limited by the IAQ Max

damper position setting. When the signal exceeds it's

setpoint (Demand Control Ventilation Setpoint) setting

and there is a call for free cooling, the actuator modu-

lates from the minimum position to the full open posi-

tion based on the highest call from either the mixed air

sensor input or the AQ voltage input.
