choice of location is possible, position unit on either north
or east side of building.
3. For ground level installation, a level pad or slab should be
used. The thickness and size of the pad or slab used
should meet local codes and unit weight. Do not tie the
slab to the building foundation.
4. For roof top installation, be sure the structure can support
the weight of the unit plus any field installed components.
Unit must be installed on a level roof curb or appropriate
angle iron frame providing adequate support under the
compressor/condenser section.
5. Maintain level tolerance of unit to 1/8" maximum.
Clearances
All units require certain clearances for proper operation and
service. Refer to Table 11 for the clearances required for
construction, servicing and proper unit operation.
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.

Ductwork
These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:
1. Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws securing
each duct cover (save these screws to use in Step 2).
2. Install the duct covers (removed in step one) to the rear
supply and return air duct openings. Secure with the four
(4) screws used in step one.
3. Seal duct covers with silicone caulk.
Duct work should be designed and sized according to the
methods of the Air Conditioning Contractors of America
(ACCA), as set forth in their Manual D.
A closed return duct system shall be used. This shall not
preclude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to
minimize the transmission of noise.
NOTE: Be sure to note supply and return openings.
Refer to Figures 5 and 6 for information concerning rear and
bottom supply and return air duct openings.
Roof Curb
On applications when a roof curb is used, the unit must be
positioned on the curb so the front of the unit is tight against the
curb.
Filters
Single phase units are shipped without a filter or filter racks. It is
the responsibility of the installer to secure a filter in the return air
ductwork or install a Filter/Frame Kit (1FF0114).
A filter rack and high velocity filters are standard on three phase
units.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by the
blower, decreasing your units efficiency and increasing
operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly; this is especially important
since this unit is used for both heating and cooling.
1. 8” Roof Curb also available.

When fastening duct work to the side duct flanges on
the unit, insert the screws through the duct flanges only.
DO NOT insert the screws through the casing. Outdoor
duct work must be insulated and waterproofed.

Condensate Drain
A condensate trap is recommended to be installed in the
condensate drain. The plumbing must conform to local codes.
Use a sealing compound on male pipe threads. Install the
condensate drain line (3/4” NPTF) to spill into an open drain.
Service Access
Access to all serviceable components is provided at the
following locations:
• Blower compartment access panel
• Electrical/Filter access panel
• Compressor access panel
• Refrigerant connections
Refer to Figures 2 and 4 for location of these access locations
and minimum clearances in Table 11.
Refer to Figure 14 for the R-410A quick reference guide.
Thermostat
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject to
drafts, sun exposure or heat from electrical fixtures or
appliances. Follow manufacturer's instructions enclosed with
the thermostat for general installation procedure. Four color
coded insulated wires (minimum #18 AWG) should be used to
connect thermostat to unit. See Figures 8 thru 10.
Power And Control Wiring
Field wiring to the unit must conform to provisions of the current
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.
The unit must be electrically grounded in accordance with local
codes or, in their absence, with the N.E.C./C.E.C. Voltage
tolerances which must be maintained at the compressor
terminals during starting and running conditions are indicated
on the unit Rating Plate and Tables 12, 13 and 14.
The wiring entering the cabinet must be provided with
mechanical strain relief.
A fused disconnect switch should be field provided for the unit.
If any of the wire supplied with the unit must be replaced,
replacement wire must be of the type shown on the wiring
diagram.
Electrical line must be sized properly to carry the load. Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
Refer to Figures 8 thru 11 for typical field wiring and to the
appropriate unit wiring diagram for control circuit and power
wiring information.
Hand tighten only.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system. Gage sets, hoses, refrigerant
containers and recovery systems must be designed to
handle R-410A. If you are unsure, consult the
equipment manufacturer. Failure to use R-410A
compatible servicing equipment may result in property
damage or injury.
Wear safety glasses and gloves when handling
refrigerants. Failure to follow this warning can cause
serious personal injury.
