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 4 inches. 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 1/2 inch maximum
across the entire length or width of the unit.

other than a York®roof curb, gasketing must be applied
to all surfaces that come in contact with the unit under-
side.
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 round lifting holes provided in the base rails.
Spreaders, whose length exceeds the largest dimen-
sion across the unit, MUST BE USED. Refer to
Figure 1.
Units may also be moved or lifted with a forklift, from
the side only, providing that an accessory skid is used.
LENGTH OF FORKS MUST BE A MINIMUM OF 90".
Refer to the Physical Data Table 5 for unit weights and
to the Figures 2 or 10 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 Unit Dimensions Figures

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 CFM and static requirements of the
job. They should NOT be sized to match the dimen-
sions of the duct connections on the unit.
Refer to Unit Dimensions Figures 11, 12 and 13 for
information concerning side and bottom supply and
return air duct openings.
FIXED OUTDOOR AIR INTAKE DAMPER
This damper is shipped inside the return air compart-
ment. It is completely assembled and ready for installa-
tion. A damper baffle inside of the hood is adjustable to
provide variable amounts of outdoor air intake on units
that are not provided with an economizer or a motor-
ized damper option. Refer to the Fixed Outdoor
Damper Figure 3.
Gasketing and mounting screws are provided in a parts
bag attached to the hood assembly. Apply gasketing to
the three flange surfaces on the hood prior to installing
the hood. Extend gasketing 1/4 inch beyond the top
and bottom of the two side flanges to insure adequate
sealing.
Adjusting the damper to the desired air flow may be
done before mounting the hood into position or after
installation by removing the front hood panel or the
screen on the bottom of the hood. Damper baffle in
position 1 will allow approximately 10% outdoor air
flow, position 2 approximately 15% and, to allow
approximately 25%, remove the damper baffle.
On units with bottom return air application install the
damper assembly over the opening in the side return
air access panel. Remove and discard the opening
cover and the covering over the hood mounting holes
(used for shipping) before installing. Secure with the
screws provided.
On units with side return air applications, install the
damper assembly on the return air ductwork as close
to the unit as possible. Cut an opening 16 inches high
by 18 inches wide in the ductwork to accommodate the
damper. Using the holes in the hood flanges as a tem-
plate, drill 9/64 inch dia. (#26 drill) holes into the duct-
work and secure with the screws provided.
CONDENSATE DRAIN
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate
drain line from the one-inch 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 drainage. See
Figure 4.
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.
If outdoor air intake will not be required on
units with bottom return air applications, the
damper assembly should still be mounted on
the side return air access panel, per the
instructions above, to insure moisture is not
drawn into the unit during operation. The cov-
ering over the mounting holes only need be
removed. Do not remove the opening cover.

COMPRESSORS
Units are shipped with compressor mountings factory-
adjusted and ready for operation.
FILTERS
Two-inch or four-inch filters can be supplied with each
unit. Filters must always be installed ahead of the
evaporator coil and must be kept clean or replaced with
same size and type. Dirty filters will reduce the capacity
of the unit and will result in frosted coils or safety shut-
down. Minimum filter area and required sizes are
shown in Physical Data Table 5.

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 11 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 CFM limitations and to Tables
7, 8 and 9 for electrical data.

OPTIONAL ECONOMIZER/MOTORIZED DAMPER RAIN
HOOD
The instruction for the optional economizer/motorized
damper rain hood can be found in the kit. Use these
instructions when field assembling 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 baffles, and all the control sen-
sors are factory mounted as part of the "Factory
installed" economizer option.
OPTIONAL POWER EXHAUST/BAROMETRIC RELIEF
DAMPER RAIN HOOD
The instructions for the power exhaust/barometric relief
damper rain hood can be found in the kit. The exhaust
fan, all supporting brackets, angles, and the wiring are
factory installed as part of the power exhaust option.
OPTIONAL 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
terminals "R" to "G" energized, turn the Minimum
Position Adjusting screw (located on the damper
control module) 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 6. 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 6.
• For a dual enthalpy operation, carefully turn the set
point adjusting screw fully clockwise past the "D"
setting.
POWER EXHAUST DAMPER SETPOINT
With power exhaust option, each building pressuriza-
tion requirement will be different. The point at which the
power exhaust comes on is determined by the econo-
mizer 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 AQ
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
accordance 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 proportionately modulated from the 2 to 10 Vdc
signal, with 2 Vdc corresponding to full closed and 10
Vdc corresponding 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
