APPLICATION
Unit Coolers are designed for use with R22, R404A,
R407A/B/C, R507 or R502 refrigerants.
At room temperatures above 34°F and evaporating
temps no lower than 27°F the air flowing through the
coil will accomplish the defrost. Temperatures of 34°F
and below (to -40°F) require positive defrosting.
(either Electric or Hot Gas).These models require the
use of (1) Time Clock (to initiate and terminate the
defrost cycle). (2) Fan-Delay thermostat (to prevent
evaporator fans from starting up right after defrost and
blowing water on to fan blades, guards and floor) (3)
Defrost Termination Control (to prevent unnecessary
prolonged heating and steaming of the coil once all
the ice and frost has melted).
The coil must not be exposed to any abnormal
atmospheric or acidic environments. This may result
in corrosion to the cabinet and possible coil failure
(leaks). (Consult manufacturer for optional baked on
phenolic protective coatings).
INSTALLATION
The installation and start-up of the Unit Coolers should
only be performed by qualified refrigeration
mechanics.
This equipment should be installed in accordance with
all applicable codes, ordinances and local by-laws.

IMPORTANT: Remember, you, the consignee, must
make any claim necessary against the transportation
company. Shipping damage or missing parts, when
discovered at the outset, will prevent later unnecessary and costly delays.
If damage or loss during transport is evident,
make claim to carrier, as this will be their responsibility, not the manufacturer’s.
Should carton be damaged, but damage to equipment
is not obvious, a claim should be filed for “concealed
damage” with the carrier.
IMPORTANT: The electrical characteristics of the
unit should be checked at this time to make sure they
correspond to those ordered and to electrical power
available at the job site.
Save all shipping papers, tags and instruction sheets
for reference by installer and owner .
LOCATION
The unit location in the room should be selected to
ensure uniform air distribution throughout the entire
space to be refrigerated. Be sure that the unit does
not draw air in, or blow directly out, through an
opened door and that the product does not obstruct
the free circulation of air. Allow a minimum of 24”
clearance at each end and behind the unit.
INSPECTION
Inspect all equipment before unpacking for visible
signs of damage or loss. Check shipping list against
material received to ensure shipment is complete.
The Unit Coolers draw air through the coil and discharge air from the fan side.
Consideration should be given to the coil location in
order to minimize the piping run length to the condensing unit and floor drain.

Page 10
MOUNTING
Mounting brackets with 7/16” dia holes are provided
for flush mounting to the ceiling. For details refer to
dimensional data on page 5. Ensure adequate clearance (at least 24”) is provided behind the coil as well
as each side (to enable access to the electrical and
refrig. compartments).
Ensure that the ceiling is level since the drain
pan has been sloped for drainage during the
defrost cycle.
DRAIN LINE
The drain line should be run from the drain connection, sloping at least 4” per foot. A trap outside the
room will prevent warm air from entering through the
tubing. Connection should be made to proper drainage
facilities that comply with local regulations.
To prevent freeze-up when the temperature of the
refrigerated space is 32
o
F or lower, the drain line
should be heated along its run inside the cold room.
The heated drain line should be insulated. It is recommended that the heater be energized at all times. A
heat input of 20 watts per foot in a 0
watts per foot in a -20
o
F room is usually satisfactory.
o
F room and 30
The drain pan may be mounted with the drain fitting at
either end (remove pan heater and relocate pan). See
page 5 for drain fitting details.
Ensure that the drain pan has sufficient slope for
proper drainage (prevention of ice build up/
blockage in pan).
PIPING
Refrigerant line sizes are important and may not be
the same size as the coil connections. (depends on
the length of run) If in doubt, consult “Recommended
refrigerant line sizes” charts. (Engineering Manuals or
other recognized sources of information).
WIRING
Wire system in accordance with governing standards
and local codes. See data and wiring diagrams on
pages 2, 3 and 4 for wiring arrangement. Electrical
wiring is to be sized in accordance with minimum
circuit ampacity rating.
For ease of identifying the proper wiring terminals, unit
wiring is colour coded and terminal block connections
are identified. When fan delay thermostats (combination fan delay and defrost termination) are installed,
on start-up, the fans do not operate until the coil
temperature is reduced to approximately
o
20
F. It is normal for the fans to cycle a few times until
the room temperature is brought down. At higher
evaporating temperatures this control may not close
and therefore should be by-passed or replaced with
an adjustable type.
The defrost termination control is adjustable
and may be set at a minimum of 40
to a maximum of 75
setting is 55
o
F. This can be increased if the hot

F (fully CCW). Normal
o
F (fully CW)
gas cycle is terminated too soon (frost still left) or
decreased if terminated too long
(steaming of coil). Time clock should be set for a
fail-safe time termination of 20 minutes.
SYSTEM CHECK
Before Start-Up:
1. All wiring should be in accordance with local
codes.
2. Refrigerant lines should be properly sized.
3. All systems should include a liquid line
solenoid valve.
4. Thorough evacuation and, dehydration has
been performed.
5. The suction, discharge, and receiver service
valves must be open.
6. The system should include a liquid line drier
moisture indicator and suction filter.
7. Pour enough water into the drain pan to allow
a good check on drainage and seal the trap.
After Start-Up:
1. If necessary , temporarily by-pass fan delay
control to run fans until room temp is lowered.
(Run jumper wire from terminal N to F on
control circuit terminal block).
2. Check the compressor oil level to ensure the
correct oil charge.
3. Be sure that the expansion valve is properly
set to provide the correct amount of
superheat. (should be around 5 to 6
o
10
F T.D. operation).
o
F for
4. Heavy moisture loads are usually encountered
when starting the system for the first time. If
the coil temperature is below freezing, this will
cause a rapid build-up of frost on the coil.
During the initial pull-down frost build-up
should be watched and the coil defrosted
manually , as required.
5. Check for proper evaporator fan blade rotation
on three phase models.
MAINTENANCE
The unit should be periodically inspected for any
dirt or build-up on the fin surface and cleaned if
necessary with a soft whisk or brush.
Also ensure coil and pan does not have any
excessive ice build-up from improper defrost
operation.
