Electrical Installation

ELECTRICAL INSTALLATION
WARNING ! When retro-fitting the cooler to an existing
installation always turn off the electrical power at the source of
the wiring. DO NOT TAKE RISKS! Turn off and tape over the
circuit breaker or remove the fuses and keep them with you until
the job is complete. Set cooler, isolator switch, wall switch,
motor and pump to "off". Be sure to tell other occupants of the
building what you are doing.
WARNING ! Check to be sure that the voltage rating of the cooler
matches your electrical system voltage.
The electrical installation must be carried out by a licensed
and qualified electrician.
Sub-circuit wiring must be rated at cooler rated amperes or
higher, and must be protected by a suitable fuse or circuit
breaker. Sub-circuit cables are to be double insulated all the way
into the cooler junction box.
Ensure that all electrical connections are tight.
connections will cause overheating that may lead to machine
damage or fire.
Replace all covers on completion of the work, using only the
screws supplied.
Do not tamper with factory wiring.
Before leaving the job, a trained,
licensed technician must check that
the cooler is operating correctly, and
must set the motor full load amps
using a clip-on ammeter. Make this
adjustment at the motor pulley
(sheave). See later detail under
heading "Operating Adjustments".

The junction box is already factory fitted to the blower housing.
Attached to the junction box is a main power supply termination box.
The main power termination box is made in two sections to facilitate
easy wiring connections. Knock-outs are provided for ½" conduit. A
hole must be drilled for ¾" conduits. (Fig. 17)
Connect the power supply and control cables inside this
termination box as shown on wiring diagram/s below.
The junction box is factory sealed; do not attempt to open it;
there are no field serviceable parts inside.
The junction box contains plug receptacles for fan motor, water pump,
and other optional features if used. Fan motor amperes must be
adjusted
on the power wires.
