Installation InstructionsWARNING! If either power cord or plug is damaged, do not use the pump. The power cord or plug

may only be repaired by a certified 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 flooding.

3.This pump can also be used to transfer water (e.g. household, farming, plumbing).

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 fitted 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 flowing 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.
