Open the electrical enclosure.

WARNING: Electrical hazard

Before performing any work on this unit, discon- nect and lock out electrical power sources to prevent injury from unexpected energization or startup.

Normally if the overload trips, resetting the overload and cor- recting the cause is typically all that is needed. However, if the overload continues to trip, it may be necessary to replace the overload module.

To replace the overload module:

1 Disconnect and lockout power to the chiller.

2	Open the electrical enclosure.

3	Locate the overload module and disconnect

the power leads from the module to the device. Refer to the wiring diagram for the exact location. Note the place- ment of each lead and label as needed.

4 Disconnect auxiliary wiring to the module.

5 Loosen the screws and remove the module.

6 Install the new module

and tighten in place with the screws.

7	Reconnect wires and leads.

8	Adjust setting to correct Full Load Amps
	rating of compressor, fan or pump.

9	Restore power to the chiller.
