2. Condenser coils must have an unlimited supply of air. Where a
choice of location is possible, position the unit on either north or
east side of building.
3. Suitable for mounting on roof curb.
Do not attach supply and return duct work to the bottom of the unit
base pan as the drain pan could be compromised.
4. 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.

WARNING
CLEARANCES
All units require particular clearances for proper operation and service.
Installer must make provisions for adequate combustion and ventilation
air in accordance with section 5.3 of Air for Combustion and Ventilation
of the National Fuel Gas Code, ANSI Z223.1 – Latest Edition (in
U.S.A.), or Sections 7.2, 7.3, or 7.4 of Gas Installation Codes, CSAB149.1 (in Canada) - Latest Edition, and/or applicable provisions of the
local building codes. Refer to Table 4 for clearances required for combustible construction, servicing, and proper unit operation.
!
WARNING
Do not permit overhanging structures or shrubs to obstruct condenser air discharge outlet, combustion air inlet or vent outlets.
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.
!
CAUTION
Before lifting, make sure the unit weight is distributed equally on the
rigging cables so it will lift evenly.
Units may be moved or lifted with a forklift. Slotted openings in the base
rails are provided for this purpose.
!
CAUTION
If a unit is to be installed on a roof curb other than a Unitary Products
roof curb, gasket or sealant must be applied to all surfaces that come
in contact with the unit underside.
!
CAUTION
All panels must be secured in place when the unit is lifted.
The condenser coils should be protected from rigging cable damage
with plywood or other suitable material.

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 are recommended to be used in the supply and return duct work to minimize the
transmission of vibration and noise.
NOTICE
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.
FILTERS
Proper filter size is very important. Filter size, type and pressure drop
should always be considered during duct system design.
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.
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.
CONDENSATE DRAIN
A condensate trap must be installed in the condensate drain. The
plumbing must conform to local codes.
DO NOT use Teflon tape or Pipe thread compound.

steps:
1. Remove the duct covers found in the bottom return and supply air
duct openings.
2. Install the duct covers (removed in step one) to the rear supply and
return air duct openings.
3. Seal duct covers with silicone caulk.
!
CAUTION
Hand tighten only.
SERVICE ACCESS
Access to all serviceable components is provided at the following locations:
• Coil guards
• Unit top panel
• Corner posts
• Blower access panel
• Control access panel
• Indoor coil access panel
• Compressor access panel
• Heat exchanger access panel
Refer to Figure 4 for location of these access locations and minimum
clearances in Table 4.
!
CAUTION
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.
!
WARNING
Wear safety glasses and gloves when handling refrigerants. Failure
to follow this warning can cause serious personal injury.
Refer to Figure 14 for the R-410A Quick Reference Guide.

THERMOSTAT
The room thermostat should be located on an inside wall approximately
60" above the floor where it will not be subject to drafts, sun exposure or
heat from electrical fixtures or appliances. Sealant should be used
behind thermostat to prevent air infiltration. Follow manufacturer's
instructions enclosed with the thermostat for general installation procedure. Color coded insulated wires (minimum #18 AWG) should be used
to connect thermostat to unit. See Figure 6. Do not use power stealing
thermostats.
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 Table 1.
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 service must be sized properly to carry the load. Each unit
must be wired with a separate branch circuit fed directly from the main
distribution panel and properly fused.
Refer to Figures 6 and 7 for typical field wiring and to the appropriate
unit wiring diagram for control circuit and power wiring information.
Minimum wire size of 18 AWG wire should be used for all field
installed control wiring.

Field-supplied external filters must be sized so as not to exceed 300 fpm air velocity through disposable
filters. For internal filter use, a filter rack kit is available. Consult the instructions supplied with that kit for
replacement filter sizes. Filter sizes: A=20x20, B=20x30.
