Before performing any work on this item, disconnect and lock out electrical power
sources to prevent injury from unexpected energization or startup. Be sure that
power to the chiller is OFF when doing any maintenance on the chiller. Follow all
safety rules when performing any maintenance on this equipment.
WARNING: Improper installation, operation or
servicing may result in equipment damage or
personal injury.
This equipment should only be installed, adjusted and serviced by a qualified
technician who is familiar with the construction, operation and potential hazards
of this type of machine.
All wiring, disconnects and fuses should be installed by a qualified electrical
technician in accordance with electrical codes in your region.
To check electrical connections:
1 Be sure the main power is disconnected and/or the chiller is locked out. Always
disconnect/unplug and lockout the main power source before opening the unit for
servicing.
2 Remove the chiller’s top lid, by first removing both side panels and then the four
(4) retaining bolts that secure the chiller’s top lid.
3 Inspect all wires and connections.
Look for loose wires, burned contacts and signs of over-heated wires. Compare
the wiring to the wiring diagrams you received with your chiller. Have a qualified
electrician make any necessary repairs or replacements.
4 Replace the chiller’s side panels and then the top lid by replacing the four (4)
retaining bolts.
5 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
in pooling water or could not be ran over and cut by wheels or casters.
NOTE: Always refer
to the wiring dia-
grams you received
with your chiller to
locate specific elec-
trical components.
