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 necessary, put a block under the pump to raise it
slightly.
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.
operation
risk of electric shock. Do not handle a
pump or pump motor with wet hands or when standing
on wet or damp surface, or in water.
1. Shaft seal depends on water for lubrication. Do not
operate pump unless it is submerged in water as seal
may be damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal
protector. If temperature in motor should rise unduly,
switch will cut off all power before damage can be
done to motor. When motor has cooled sufficiently,
switch will reset automatically and restart motor. If
protector trips repeatedly, pump should be removed
and checked as to cause of difficulty. Low voltage,
long extension cords, clogged impeller, very low head
or lift, etc., could cause cycling.

3. Pump will not remove all water. If manually operated
pump is operating and suddenly no water comes out
discharge hose, shut OFF unit immediately. Water
level is probably very low and unit has broken prime.
note: For continuous operation, water must flow
through pump to prevent motor overheating. The
pump is cooled by the water flow through the housing.
4. Pump can run when water doesn't completely cover
the motor housing, but the inlet must be completely
submerged or it will break suction and will not move
any water.
5. Keep the pump inlet clean at all times. If the ground
or surface where the pump sits is dirty, raise the pump
slightly to reduce the amount of debris pulled into the
pump inlet.
6. If you need to reduce the flow, restrict the discharge.
Do not restrict the intake. Restricting the intake will
starve the pump for water and can cause overheating.
note: No repair parts available.
