WARNING! If either power cord or plug is damaged,
do not use the pump. The power cord or plug
may only be repaired by a certied electrician.
Areas of use
1. This pump is designed to pump clear water only.
2. This pump is designed for use as a basement pump.
When installed in a shaft, this pump provides
some protection from basement ooding.
3. This pump can also be used to transfer water
(e.g. household, farming, plumbing).
Installation Instructions
1. Construct a basin that is at least 22 IN. deep
and at least 14 IN. in diameter.

away from all obstructions throughout its movement.

3. Fit a sump cover with a hole for the output pipe
and power cords. Thread the Power Cords
through their holes, but do not plug them in yet.
Set the sump cover aside for now.
Note: The sump cover can also be
tted with a vent pipe, if desired.
4. Attach a discharge pipe to the Pump Outlet.
Note: Wrap all threaded connections
with PTFE thread seal tape.

5. To prevent needless cycling, install a check valve
onto the discharge pipe. This prevents water
from owing back after the pump shuts off.
6. IMPORTANT: Drill a
1
/
8
IN. diameter air bleed hole
through the Discharge Pipe just above the lower Base
to prevent Pump “airlock”. A small spray of water
out of this hole is normal while the Pump is running.
7. Install a gate valve or ball valve if
required by building codes.
8. The ON/OFF height can be changed
by adjusting the Float Switch.
9. Connect additional Discharge Pipe as needed
to direct the water discharge at least 3 FT.
away from the foundation. Slope the discharge
pipe downward, away from the foundation.
The discharge should be kept as short as
possible with a minimum number of turns.
IMPORTANT: Do not exceed the
Maximum Delivery Height of the Pump.
