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:

1Be 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.

2Remove 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.

3Inspect 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.

4Replace the chiller’s side panels and then the top lid by replacing the four (4) retaining bolts.

5Inspect 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.
