1. Check evaporator voltage to ensure that pump voltage is correct.

NOTE: EVAPORATOR POWER SUPPLY MAY BE USED IF COMPLIANT WITH NEC AND LOCAL

CODE REQUIREMENTS. IF PUMP IS POWERED BY AN INDEPENDENT SUPPLY, POWER MUST

BE AVAILABLE AT ALL TIMES DURING COOLING OPERATION TO ENSURE CONDENSATE

EVACUATION AND PROVIDE PUMP OVERFLOW PROTECTION.

2. Install 1 amp inline fuse between the power supply and the pump.

3. Connect pump power cable to the power supply. To use evaporator power supply, connect precisely as

shown in diagram below.

4. Break wire 3 and re-connect as shown in diagram using grey and purple wires only.

NOTE: OVERFLOW ALARM WIRE MUST BE CONNECTED TO ENSURE THAT IN CASE OF

PUMP FAILURE OR BLOCKAGE IN DISCHARGE HOSE, EVAPORATOR WILL SHUT DOWN.

CONNECTION OF THE OVERFLOW ALARM CIRCUIT IS MANDATORY AND

FAILURE TO DO SO WILL INVALIDATE PUMP WARRANTY!
