General

UP ZS units are single package air conditioners with optional
gas heating designed for outdoor installation on a rooftop or
slab and for non-residential use. These units can be equipped
with factory or field installed electric heaters for heating
applications.

These units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory installed and tested. The units require electric
power, gas supply (where applicable), and duct connections.
The electric heaters have nickel-chrome elements and utilize
single-point power connection.

Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury. Improper installation,
adjustment, alteration, service or maintenance can
cause injury or property damage. Refer to this manual.
For assistance or additional information consult a
qualified installer, service agency or the gas supplier.

Wear safety glasses and work gloves. Use quenching cloth and
have a fire extinguisher available during brazing operations.

Inspection

As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of th e
damage should be noted on the carrier’s freight bill. A separate
request for inspection by the carrier’s agent should be made in
writing.

This product must be installed in strict compliance with
the enclosed installation instructions and any applicable
local, state and national codes including, but not limited
to, building, electrical, and mechanical codes.

The furnace and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing at pressures in excess of 1/2 PSIG.

Pressures greater than 1/2 PSIG will cause gas valve
damage resulting in a hazardous condition. If it is
subjected to a pressure greater than 1/2 PSIG, the gas
valve must be replaced.

The furnace must be isolated from the gas supply piping
system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 PSIG

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.

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.

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.

Compressors

The scroll compressor used in this product is specifically
designed to operate with R-410A Refrigerant and cannot be
interchanged.

This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be

Figure 18: Return Downflow Plenum With Panel

16 Johnson Controls Unitary Products

used in this system.

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
designed for HCFC and CFC refrigerants. Take all necessary
precautions to avoid exposure of the oil to the atmosphere.

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

POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.

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.

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.

518676-BIM-E-1210

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.

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 208­3-60 or 380-3-50 operation. See unit wiring diagram.

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 Unitary Products supplied accessory), refer to
Figure 4 for the recommended mounting location.

Units are shipped with compressor mountings which are
factory-adjusted and ready for operation.

Do not loosen compressor mounting bolts.

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.

Make sure that panel latches are properly positioned on
the unit to maintain an airtight seal.

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.

Avoid damage to internal components if drilling holes for
disconnect mounting.

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, 23 and 24 for typical field wiring and to
the appropriate unit wiring diagram mounted inside control
doors for control circuit and power wiring information.

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.

Power Wiring Detail

Units are factory wired for the voltage shown on the unit
nameplate. Refer to Electrical Data Table 8 to size power
wiring, fuses, and disconnect switch.
