Installation / Operation

INSTALLATION

1. Install the pump on a hard level surface. Make sure
that the pump cannot pick up rocks, mud and debris,
etc. If neccesary, put a block under the pump to raise
it slightly. See Figure 1.

2. Protect the power cord from damage. Uncovered
cords should be routinely inspected for damage or
deterioration. DO NOT operate the pump if the cord
is damaged.
3. Choose an adapter and install it as indicated in
Figure 2.

OPERATION

Hazardous voltage. Can shock, burn or
cause death. Do not handle a pump or pump motor with
wet hands or when standing on a wet or damp surface, or
in water.
1. The shaft seal depends on water for lubrication. Do
not operate the pump unless it is in water as the seal
may be damaged if allowed to run dry.
2. The motor is equipped with an automatic reset ther-
mal protector. If the temperature in the motor should
rise unduly, the switch will cut off all power before
damage can be done to the motor. When the motor
has cooled sufficiently, the switch will reset automati-
cally and restart the motor. If the protector trips
repeatedly, remove the pump and check it as to the
cause of difficulty. Low voltage, long extension cords,
clogged impeller, very low head or lift, etc., could
cause cycling.
3. The pump will not remove all water. If the pump is
operating and suddenly no water comes out of the
discharge hose, shut off the unit immediately. The
water level is probably very low and the unit has bro-
ken prime.
NOTICE: For continuous operation, water must flow
through pump to prevent motor overheating. The
pump is cooled by the water flow through the housing.
4. This pump is designed to pump cold water only.
Pumping heated liquids can overheat the motor and
cause the thermal overload to trip.
5. Pump can run when water doesn't completely cover
the motor housing, but the inlet must be completely
submerged or it will break suction, will not move any
water, and may damage the shaft seal.
NOTICE: For continuous operation the water depth
must be at least 5" (13 cm) to prevent the pump from
overheating.
6. Keep the pump inlet clean at all times. If the ground
bottom or surface where the pump sits is dirty, raise
the pump slightly to reduce the amount of debris
pulled into the pump inlet.
7. If you need to reduce the flow, restrict the discharge.
Do not restrict the intake. Doing so will starve the
pump for water and can cause overheating.
