Replacement Procedures

Isolating Electrics

The chiller should be isolated from the power supply before attempting

any

maintenance. Use the isolating switch and plug, located in the refrigeration
unit compartment, to turn off the electrics to the cabinet and refrigeration unit
without unplugging the cabinet from the wall.

To isolate the electrics

1. Remove the front panel

from the cabinet by
undoing the fixing screws
near the bottom of the
panel and lifting it up and
off the cabinet.

2. Switch off (O) the power at

the mains isolation switch
and unplug the mains IEC
plug on the LH side of the
refrigeration unit
compartment.
