INSTALLATION INSTRUCTIONS
DRAIN LINE
If unit cooler is mounted flush to ceiling, the staggered
heigh hanger will provide a positive pitch for drainage of
condenser.
If units are suspended below the ceiling, the installer
should provide adequate pitch to the unit by adjusting
the location of the hanger rod nuts.
Note: Check for adequate drainage by pouring water into
the drain pan.
Insulated copper tube should be run from the drain
connection, sloping at least 4” (102mm) per foot. A trap
outside of the room will prevent warm air entering
through the tubing. Connection should be made to
proper drainage facilities that comply with local
regulations.
If room temperatures are below freezing, it is necessary
to heat the drain line to prevent condensate from
freezing in the drain line. Electric heating cable or
electric tape (by others) is used for this purpose. The
drain line heater should be connected for continuous
operation; it is also recommended that the drain line be
insulated. A heat output of 20 watts per lineal foot of 1”
(25mm) drain line in a 0°F (-18 °C) room is usually
satisfactory. 115 volt cable and tape is available from
your local refrigeration wholesaler. Two 115 volts heaters
(by others) of the same wattage may be wired for use on
230 volt system
ELECTRICAL
Wire system in accordance with governing standards
and local codes. See wiring diagrams on P. 4 for unit
cooler wiring diagram.
Page 2 shows operating current, minimum ampacity and
maximum fuse sizing for fan motors.
Note: Electrical wiring is to be sized in accordance with
minimum ampacity rating.
The defrost termination thermostats, fan delay
thermostats and defrost heater safety thermostat are
factory supplied and factory wired to a terminal block.
See figure and component identification diagram on
wiring diagram for electrical compartment arrangement.
A hinged end panel provides quick access to the
electrical compartment.
INSPECTION
C
areful inspection of all parts when received for loss or
damage in transit is very 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.
Ensure that the electrical characteristics are as ordered.
Save all tags and instruction sheets for reference by
installer and owner.
LOCATION
The unit location in the room should be selected to ensure
uniformair distribution throughout the entire space to be
refrigerated. Make sure that the fan does not blow directly
out or pull in through an opened door and that the product
does not obstruct the free circulation of air.
When installing the unit adjacent to a wall, sufficient
clearance must be provided to allow free air movement to
the coil.
Clearance must be provided at each end of the unit to
allow access to refrigerant piping and electrical
compartment.
See dimensional drawings for clearance requirements.
INSTALLATION
Note: These units draw air through the coil and
discharge air from the fan side (see P. 4).
JBC Unit Coolers are supplied with shipping legs to allow
units to be shipped in an upright position. Units are lifted
into place with shipping skid attached to mounting legs.
Slotted hanger brackets take 1/2” (12.7mm) hanger rods.
For fast, convenient mounting, install washer and nuts on
hanger rods prior to lifting units. Rods may be lifted into
slots and are held securely in place by tangs on hangers
After unit coolers are hung in place, remove shipping legs
from units by removing the two 5/16” (8mm) bolts from
each shipping leg.
Note: Shipping legs must be removed to allow hinged
drain pan to open.
