INSTALLATION
Wiring to the cooler must be rated at cooler rated amperes
or higher, and must be protected by a suitable fuse or circuit
breaker. Cables are to be double insulated all the way into the
cooler junction box.
Ensure that all electrical connections are tight. Loose
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 Power Pack fitted in this cooler contains a junction box with
main power supply termination box attached.
Connect the power supply and control cables inside this
termination box as shown on "WIRING DIAGRAMS" on Page
9.
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 before closing the
termination box using a clip-on ammeter on the power wires.
