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.
Figure 3: DEZ/DEQ/DEX Unit 4 Point Load Location
If a unit is to be installed on a roof curb other than a
Unitary Products roof curb, gasketing must be applied to
all surfaces that come in contact with the unit underside.
Before lifting, make sure the unit weight is distributed
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 rigging
cable damage with plywood or other suitable material.

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.
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 10.
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, 9 and 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 11, 12 and 13.
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,
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.
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.

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 and 11 for typical field wiring and to the
appropriate unit wiring diagram for control circuit and power
wiring information.

Compressors
The compressors used in this product are specifically designed
to operate with R-410A Refrigerant and cannot be
interchanged.
The compressors also use a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hydroscopic, meaning it absorbs
water readily. POE oil can absorb 15 times as much water as
other oils designed for HCFC and CFC refrigerants. Take all
necessary precautions to avoid exposure of the oil to the
atmosphere.
POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.
Procedures which risk oil leakage include, but are not limited to,
compressor replacement, repairing refrigerant leaks, replacing
refrigerant components such as filter drier, pressure switch,
metering device or coil.
Units are shipped with compressor mountings which are
factory-adjusted and ready for operation.
Phasing
Three-phase, scroll compressors operate in only one direction.
If the scroll is drawing low amperage, has similar suction and
discharge pressures, or is producing a high noise level, the
scroll is misphased. Change the incoming line connection
phasing to obtain the proper rotation.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.
Do not leave the system open to the atmosphere. Unit
damage could occur due to moisture being absorbed by
the POE oil in the system. This type of oil is highly
susceptible to moisture absorption
Exposure, even if immediately cleaned up, may cause
embrittlement (leading to cracking) to occur in one year
or more. When performing any service that may risk
exposure of compressor oil to the roof, take precautions
to protect roofing.
Do not loosen compressor mounting bolts.
Scroll compressors require proper rotation to operate
properly. Failure to check and correct rotation may result
in property damage.
