Operation
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.
Adjusting the Flow
The drain pump can pump up to 21 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.
Run water into the sink. The pump will start when it detects water.
Check for leaks. If leaks are found, unplug the pump power cord and fix the leaks before proceeding.
Put a stopper in the drain and allow the sink to fill up a few inches.
Open the discharge shut-off valve, open the faucets, and remove the stopper to drain the sink.
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 when the washing machine discharges into it, unless the sink is ONLY
used for washing machine discharge.
NOTE: 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.
