Ductwork
Ductwork should be designed and sized according to the
methods in Manual D of the Air Conditioning Contractors of
America (ACCA) or as recommended by any other recognized
authority such as ASHRAE or SMACNA.
A closed return duct system should be used. This will 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 pressure requirements of the job. They
should NOT be sized to match the dimensions of the duct
connections on the unit.
Refer to Figure 10 for bottom air duct openings. Refer to
Figures 12, 13 and Table 6 for side air duct openings.

Duct Covers
Units are shipped with the side duct openings covered and a
covering over the bottom of the unit. For bottom duct
application, no duct cover changes are necessary. For side
duct application, remove the side duct covers and install over
the bottom duct openings. The panels removed from the side
duct connections are designed to be reused by securing each
panel to its respective downflow opening. But keep in mind that
the supply panel is installed with the painted surface UP, facing
the heat exchanger, while the return panel is installed with the
painted surface DOWN, facing the downflow duct opening. The
supply panel is secured with the bracket (already in place from
the factory) and two screws. It’s a snug fit for the panel when
sliding it between the heat exchanger and unit bottom, but there
is room. The return panel is secured with four screws.
Figure 17: Side Panels With Hole Plugs
NOTE: Orientation. Panel is “insulation” side up.
Figure 18: Return Downflow Plenum With Panel
Figure 19: Discharge Panel In Place
Condensate Drain
The side condensate drain is reversible and maybe re-oriented to
the rear of the cabinet to facilitate condensate piping. A
condensate drain connection is available through the base pan
for piping inside the roof curb. Trap the connection per Figure 20.
The trap and drain lines should be protected from freezing.
Plumbing must conform to local codes. Use a sealing compound
on male pipe threads. Install condensate drain line from the 3/4
inch NPT female connection on the unit to an open drain.
Figure 20: Condensate Drain
Compressors
The scroll compressor used in this product is specifically
designed to operate with R-410A Refrigerant and cannot be
interchanged.
The compressor also uses a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hygroscopic,meaning it absorbs water
readily. POE oil can absorb 15 times as much water as other oils
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 water-proofed.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.
OPTIONAL COIL
GUARD
3" Minimum

267234-BIM-C-1208
Johnson Controls Unitary Products 15
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.
Filters
Two-inch filters are supplied with each unit. One-inch filters may
be used with no modification to the filter racks. Filters must
always be installed ahead of evaporator coil and must be kept
clean or replaced with same size and type. Dirty filters reduce
the capacity of the unit and result in frosted coils or safety
shutdown. Refer to physical data tables, for the number and
size of filters needed for the unit. The unit should not be
operated without filters properly installed.
Power And Control Wiring
Field wiring to the unit, fuses, and disconnects must conform to
provisions of National Electrical Code (NEC), ANSI/NFPA No.
70 – Latest Edition (in U.S.A.), current Canadian Electrical
Code C221, and/or local ordinances. The unit must be
electrically grounded in accordance with NEC and CEC as
specified above and/or local codes.
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 internal wiring harnesses furnished with this unit are an
integral part of the design certified unit. Field alteration to
comply with electrical codes should not be required. 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 minimum gauge as the replaced wire.
A disconnect must be utilized for these units. Factory installed
disconnects are available. If installing a disconnect (field
supplied or UP supplied accessory), refer to Figure 4 for the
recommended mounting location.
NOTE: Since not all local codes allow the mounting of a
disconnect on the unit, please confirm compliance with
local code before mounting a disconnect on the unit.
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 Figures 21, 22 and 23 for typical field wiring and to the
appropriate unit wiring diagram mounted inside control doors
for control circuit and power wiring information.
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.
Make sure that panel latches are properly positioned on
the unit to maintain an airtight seal.
208/230-3-60 and 380/415-3-50 units control
transformers 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.
Avoid damage to internal components if drilling holes for
disconnect mounting.
When connecting electrical power and control wiring to
the unit, water-proof connectors must be used so that
water or moisture cannot be drawn into the unit during
normal operation. The above water-proofing conditions
will also apply when installing a field supplied disconnect
switch.

nameplate. Refer to Electrical Data Table 8 to size power
wiring, fuses, and disconnect switch.
Power wiring is brought into the unit through the side of the unit
or the basepan inside the curb.
Figure 21: Field Wiring Disconnect - Cooling Unit With/Without Electric Heat
Thermostat Wiring
The thermostat should be located on an inside wall
approximately 56 inch above the floor where it will not be
subject to drafts, sun exposure or heat from electrical fixtures or
appliances. Follow the manufacturer's instructions enclosed
with thermostat for general installation procedure. Seven (7)
color-coded, insulated wires should be used to connect the
