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 one of the three pump inlets. Be sure inlet piping is sloped downward to allow gravity flow (Figure 4). Extend the inlet piping into the tank from 1 to 3 inches to ensure that it will not interfere with proper float operation. Be sure that the inlet piping is cut at an angle where it enters the tank. 2. The outlet piping should be flexible tubing secured with a hose clamp (not provided) or pipe (3/8 inch I.D. maximum to prevent excessive flow back to unit). From condensate unit, extend discharge piping straight up as high as necessary. Do not extend this line above the head/GPH of the particular model being installed. From this high point, slope discharge line down slightly to a point above drain area; then turn down and extend to a point below or approximately level with the bottom of the condensate unit. This will give a siphoning effect which will improve efficiency of the condensate unit and will, in most cases, eliminate the need for a check valve (Figure 5). If it is not possible to slope discharge line down, make an inverted “U” trap directly above the pump at the highest point. 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 switch float with finger (Figure 6). Motor should turn on just before float contacts cover. 4. Test safety switch by raising safety switch float with finger. Safety switch should activate before float contacts cover. 5. Replace motor/tank cover assembly on tank. This pump is suitable for gas furnace condensate applications. Caution must be taken to ensure acidity of condensate does not increase below the average pH of 3.4 (to prevent localized pocket of acid that acts like a battery causing pitting) by routinely cleaning or flushing tank with fresh water.
