Installation 3

PUMP INSTALLATION

Mount the pump

NOTICE: DO NOT use plumber’s pipe threading

compound (“pipe dope”) on plastic pipe; it can damage the plastic, causing leaks and piping failure and voiding the warranty.

1. Place the sink in its final location.

2. Remove any existing drain fittings back to the tail piece (Figure 1). Make sure the existing tail piece does not leak. NOTICE: If the sink-drain tail piece is not 1-1/2" NPT, you will have to adapt it (bushings, reducers, etc.). In this case, wrap all joints with PTFE pipe thread sealant tape before making connections.

3. Glue the 1-1/2” PVC pipe into the female adapter (purchase separately).

follow the cement manufacturer’s instructions when using PVC cement. Do not use near fire or open flame.

4. Wrap the threads of the tail piece with 1 to 1-1/2 turns of PTFE pipe thread sealant tape. Thread the 1-1/2" NPT female adapter onto the sink-drain tail piece. Thread it hand tight plus 1/2 turn with a pipe wrench or slip joint pliers. DO NOT overtighten.

* Required and included ** Purchase separately †

For easier removal for servicing or cleaning,

install a 1-1/2” solvent union in the drop pipe.

5. Wrap the threads of the 1-1/2” male adapter with 1 to 1-1/2 turns of PTFE pipe thread sealant tape and install it in the pump inlet. Tighten it hand tight plus 1/2 turn with a pipe wrench or slip joint pliers. DO NOT overtighten!

6. Measure the 1-1/2” PVC pipe against the drain and the pump and trim the pipe to fit.

7. Do a trial assembly (dry - no glue) of the pump onto the drain pipe. Swing the pump until it accurately faces the discharge piping, and then mark the pump and the inlet pipe/adapter assembly so that you can accurately install the pump in Step 8. Arrange a temporary support under the pump to relieve the strain on the sink drain piping while the glue is setting. Leave it in place while you measure and cut the discharge piping (Step 12).

8. Slide the pump up into position and glue the pipe into the male adapter (on the pump).

• Don’t allow any glue to get on the pump or in

the motor;

• Make sure the pump is facing the correct direction

(match the marks from Step 7);

• Put the support in place under the motor.

9. Wrap the 1-1/4” galvanized nipple with 1-1/2 to 2 turns of PTFE pipe thread sealant tape on each end and thread it into the pump discharge port. NOTICE: Tighten this only enough to prevent leaking. Over-tightening can crack the plastic.

10. Hold the nipple with a pipe wrench and thread one half of the 1-1/4” union onto it, hand tight plus 1-1/2 turns with a pipe wrench or slip-joint pliers.

11. At this time, wrap the threads on both the 1-1/4” male adapters with 1-1/2 to 2 turns of PTFE pipe thread sealant tape. Thread one of the adapters into the other half of the 1-1/4” union, hand tight plus 1/2 turn with a wrench or a pair of slip-joint pliers. DO NOT overtighten!

12. Install the discharge piping as shown in Figures 1 and 2. The order is:

1-1/4” PVC Pipe cut to fit, 90° Socket to Socket elbow, 1-/14” PVC Pipe cut to fit, Male adapter, Flow Control/Ball Valve,

Check Valve,

(NOTICE: Install the check valve in the vertical

discharge pipe with the threads down. Be sure the flow arrow points AWAY from the pump. That is, when the check valve is correctly installed, the arrow showing direction of flow should point UP.)

1-1/4” Outlet Pipe.

13. Connect the discharge piping to the building drain.

Plug in the Pump

AFTER the pump is completely installed, plug the switch into a GFCI-protected, properly grounded outlet. Plug the pump into the back of the switch’s plug.

Installation / Maintenance 4

Adjusting The Flow

The drain pump can pump up to 27 gallons per minute (GPM). Normal sink drains allow only 5 to 6 GPM to flow. Adjust the discharge shut-off/flow balancing valve as follows so that the pump does not cycle on and off when the faucets are on full.

1. Run water into the sink. The pump will start when it detects water.

2. Check for leaks. If leaks are found, unplug the pump power cord and fix the leaks before proceeding.

3. Put a stopper in the drain and allow the sink to fill up a few inches.

4. Open the discharge shut-off valve, open the faucets, and remove the stopper to drain the sink.

5. The pump will start. Adjust the discharge shut-off/flow balancing valve until the pump runs continuously while the faucets are running and the sink is draining. If the water level rises with the pump on, slightly open the discharge valve to balance the flow. If it drops, slightly close the discharge valve.

Washing Machine Use

Washing machines usually discharge more water than the faucets do, and it is normal for the water level to rise in the sink while the pump is discharging. Do not adjust the discharge valve to match the flow w hen the washing machine discharges into it, unless the sink is ONLY used for washing machine discharge.

NOTICE: Washing machine discharge water contains fiber and lint. Unfiltered washing machine discharge could plug the pump and require pump disassembly for cleaning. To avoid this, install a lint trap or bag type filter in the washing machine discharge line and clean it out regularly.

MAINTENANCE

This pump requires very little maintenance and should provide a long service life. Problems are rare; when the pump flow drops off, the most likely cause is something solid going down the drain and jamming the impeller.

To clear a jammed impeller:

1. Unplug the Pump.

2. Close the discharge shutoff valve.

3. Bail out the sink as much as possible.

4. Disconnect the union, unscrew the pump from the sink tail piece, lower the pump to the floor, and slide it out from under the sink (see Figure 3).

5. Remove the six housing screws (see Figure 4).

6. Clean out the pump. Make sure that the pump discharge is clear. If necessary, replace the impeller.

7. Install the new gasket (included with impeller). Reassemble the pump.

8. Raise the pump back into position, thread it back onto the sink tail piece, and reconnect the union.

9. Plug in the pump. Run water in the sink until the pump has run at least one complete cycle to make sure the pump is operating correctly and there are no leaks.
