Be sure the main power is disconnected
and the chiller is locked out. Always disconnect and lockout the main power source
before opening the unit for servicing.
2
Open the electrical enclosure.
3
Inspect all wires and connections.
Look for loose wires, burned contacts, and signs of over-heated wires. Compare
the PLC wiring to the wiring diagrams you received with your chiller. Have a qual-
ified electrician make any necessary repairs or replacements.
4
Close the electrical enclosure door.

Inspect the exterior power cords.
Cords should not be crimped, exposed, or rubbing against the frame. If the main
power cord runs along the floor, make sure it is positioned where it could not rest

NOTE: Always refer
to the wiring dia-
grams you received
with your chiller to
locate specific elec-
trical components.
