OPERATING INSTRUCTIONS AND PARTS MANUAL
DESCRIPTION
This portable, Auto On-Off Pool Cover pump is designed for automatic
removal of water, from a pool or spa cover. The units are equipped
with a 25 ft. 3-prong grounding type power cord (WAPC250) or GFCI
Protected Power Cord (WAPC250G). The provided discharge check
valve prevents short cycling and it's 3/4 in. adapter can be used for
convenient attachment to a standard garden hose.

APPLICATION AND OPERATION

This unit is not designed for use as a sump pump or in sump
applications. This unit is not designed for use in septic tanks or
underground vaults to pump raw sewage or effluents. Never use in
hazardous or explosive locations.
PUMPING HEIGHT
When water is pumped to an elevated position, any volume that has not
reached the discharge outlet can flow back through the pump when
the pump shuts off. This back-flow can cause the water level in small
areas to rise enough to re-start the pump. The check valve/hose adapter
included is required in this situation. For proper operation, make certain
the check valve is oriented as instructed on check valve body.
In small areas a check valve is required to
prevent backflow. Without a check valve the pump may cycle continuously
and potentially wear out the pump components.
1. This pump has been designed with 1-1/4 in. NPT discharge
connection size. Attach pipe or fitting to the discharge or use the
supplied garden hose adapter/check valve. Thread the female end of
the garden hose to the male end of the garden hose adapter/check
valve.
2. Use a hose washer (not included) on the garden hose for correct
pump operation.
3. For best pump performance, unwind the hose before starting the
pump. This will help remove any kinks or binds in the hose and allow
the unit to pump with less restriction.
DO NOT place the pump on a weak, damaged,
or leaking pool cover. Placing the pump on a damaged pool cover could
cause the cover to give way, or could allow the pump to remove treated
swimming water from the pool in addition to rainwater.
4. Install the "snap-on" debris strainer. Begin by lining up the pump
base profile with the profile of the strainer base using the switch
housing as a guide. Tilt the pump back and guide the rear of the
pump (opposite the discharge) into the strainer base. Once the rear
of the pump is in place, gently rotate the pump down until the latch
engages.
5. To remove debris strainer release latch and guide pump out of
strainer in the reverse motion of installation.
6. With pump unplugged set the pump on the pool cover, where water
will collect. Do not set the pump directly on mud, sand surfaces or
in leaves. For best results make sure the pump strainer is making full
contact with a clean area of the pool cover. This will allow the strainer
to properly filter debris and help prevent clogging of the pump. If
necessary clear an area of the pool cover before placing the pump.
For further placement techniques see (Figures A-E).

pool cover where water will collect.
A3. Do NOT exceed the 13 ft. maximum pumping height for this pump or
switch may not function properly. Plug in pump to allow for automatic
