The pump is controlled by a float/switch mechanism which turns the pump on when approximately 2-1/4" of water collects in the tank, a

TO REDUCE THE RISK OF ELECTRICAL SHOCK, BE CERTAIN THAT IT IS CONNECTED TO A PROPERLY GROUNDED GROUNDING TYPE RECEPTACLE. IN ANY INSTALLATIONS WHERE PROPERTY DAMAGE AND/OR PERSONAL INJURY MIGHT RESULT FROM AN INOPERATIVE OR LEAKING PUMP DUE TO POWER OUTAGES, DISCHARGE LINE BLOCKAGE, OR ANY OTHER REASON, A BACKUP SYSTEM(S) AND/OR ALARM SHOULD BE USED. SUPPORT PUMP AND PIPING WHEN ASSEMBLING AND WHEN INSTALLED. FAILURE TO DO SO MAY CAUSE PIPING TO BREAK, PUMP TO FAIL, MOTOR BEARING FAILURES ETC. I

SERVICE INSTRUCTIONS 1. Make certain that the unit is disconnected from the power source before attempting to service or remove any component! 2. Be sure the floats move freely. Clean as necessary (Figure 6). 3. Clean the tank with warm water and mild soap. 4. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the line that would inhibit flow. TESTING 1. Turn on power. 2. Remove motor/tank cover assembly and hold level. 3. Test motor switch by raising motor swit

The COM and NC switch contacts may be used to actuate a low voltage alarm circuit (connected in series) if the heating/cooling system can not be disrupted. The safety switch comes from the factory with leads connected to the COM and NO switch terminals. Typical hook-up of “NC” circuits would be (Figures 2 & 3). 4. If fused plug is used on 230V units, a 1.0 amp fuse is recom- mended. Figure 1. Figure 2. Figure 3. Figure 4. Figure 5. PIPING 1. Run flexible tubing or pipe from evaporator drain into
