Please note!
1. Do not install the pump by suspending it
unsupported from its delivery pipe or power cords.
The pump must be suspended from the
handle or be placed on the bottom of the shaft.
To ensure that the pump works properly,
keep the bottom of the shaft free from
sludge and dirt of all kinds.
2. If the water level sinks too low, any sludge in the
shaft will dry out and stop the pump from starting.
To help ensure the pump will start as required,
check the pump regularly with start-up tests.
Power Supply
1. The pump is equipped with a shock-
proof plug according to regulations.
The pump is designed to be connected to
120 V~, 60 Hz, Ground Fault Circuit Interrupter
(GFCI) protected safety socket.

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 1/8IN. 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.

10. After connecting power to the pump and
periodically afterwards, test the pump:
a. Fill the basin to above the Float Switch Operation
ON Height. The pump should start pumping.
b. The pump should pump the water down
to below its Float Switch Operation OFF
Height and then stop pumping.
c. If the water drains back into the basin and
restarts the pump, make sure the check
valve is properly installed and working.
Also make sure that all pipe connections are tight.
Note: It is the owner’s responsibility to ensure the
oat switch is properly connected to the pump and can
operate properly and freely without obstructions.
