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).
Fire and explosion hazard. Be sure to 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.
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).
•
No glue on the pump or in the motor;
•
Make sure the pump is facing the right 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° Soc. to Soc. 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.
