Page 8 Certification: UL & cUL Listed Weight: 3.25 lbs Dimensions: 11" X 5" X 4-3/4" Tank Capacity: 2 qts. Total Motor Ratings: ThermallyProtected, Double Insulated Enclosure Page 2 INSTALLATION 1. Carefully unpack the unit. Check for damage and make sure all of the required parts are included. The units are thoroughly tested before packing to insure safe delivery and operation. If there is any sign of damage due to shipment return it to the place of purchase for repair or replacement. 2. Choose a mounting location near the air conditioner or furnace. The pump must be mounted level and the inlet must be below the lowest drain. The unit has two brackets built into the deck that can be used to attach the unit to a wall or to the side of the appliance with installer supplied fasteners. 3. The pump should be mounted so the deck is at least 6 1/2" above the floor. (See Figure 1) This will allow clearance for the tank to be removed later for cleaning. CONNECTING THE PIPING 1. Run flexible tubing or pipe from the condensate drain on the evaporator pan and/or drain from furnace to one of the inlet holes on the pump. This drain line should have a continuous downward slope to allow gravity flow. Cut the end of the line at an angle so the end does not close off on the bottom of the pump's tank. (See Figure 2) NOTE: If there is an overflow drain from the evaporator pan or from the furnace, it may be necessary to tee the overflow and the main drain together before they enter the pump. (See Figure 1) 2. Connect a discharge line to the barbed check valve on top of the pump. This line may be flexible tubing or rigid pipe, but must be no larger than 3/8" I.D. Extend the discharge line straight up from the pump to the highest point possible without exceeding the head/GPH capacity of the pump before directing the line to the drain. From this high point, run the discharge line to a drain with a downward slope. For best results, the drain should be below or approximately level with the bottom of the pump tank. If it is not possible to slope the line downward, make an inverted "U" trap at the high point of the discharge line above the pump. (See Figure 2) NOTE: Although not needed for this pump, local codes may require the use of a condensate neutralizer when using this pump with a condensing gas furnace. Consult local codes for guidelines. WIRING Shut off electrical power at the fuse box before making any wiring connections. All wiring must be done according to local and/or applicable national codes. 1. Main Power: Unit is provided with a 6 foot long power cord. Connect this cord to a constant line voltage source, not a fan or other device that may run intermittently. 2. Safety Switch: If using the model 20+ULS or 20+ULST, the overflow safety switch may be wired in series with the appliance's thermostat to shut off the unit in the event that the pump fails. In the case where heating or cooling requirements are a necessity, the overflow safety switch may be wired into an alarm circuit. Refer to Figure 3 for wiring. Note: In most cases, use the normally closed (NC) contacts when used with a furnace or air conditioner and use the normally open (NO) contacts when used to trigger an alarm. Figure 1 Figure 2 Figure 3 Page 3 TESTING 1. With the unit plugged in and the discharge line in place, pour water into the pump reservoir until the unit activates to verify the unit works. 2. To test the overflow safety circuit (Models 20+ULS and 20+ULST only): a. Energize the appliance so it runs. b. Kink the tube coming from the pump discharge, or unplug the power cord, so it cannot pump out. c. Pour water into the pump reservoir, filling it completely. d. As the water level nears the top of the unit the overflow safety switch should activate, breaking the thermostat circuit to the appliance (or triggering an alarm circuit, if used.) e. Un-kink the tube, or plug the cord back in, and allow the pump to empty the tank. As the water level goes down the overflow safety switch will deactivate and the appliance...
