Installation
DESCRIPTION
These submersible pumps are designed for use in water-
fall/ fountain applications or as a utility pump. The units
are equipped with a 3-prong grounding-type power cord.
Ball bearings on motor shafts never need lubrication.
Automatic reset thermal protection.

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. If used with a fountain jet, position the
pump so that the fountain jet is above the surface of
the water.
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. If used in a garden pond, use an adjustable diverter
valve (purchase separately) to control the fountain
spray height and flow over the waterfall. Do not
restrict pump suction to adjust flows. Restrictng the
suction will starve the pump for water and can dam-
age the pump.
4. If the pump is connected to a pond filter, use an
adjustable diverter valve to provide adequate flow to

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. 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. When used as a utility pump, the pump will not
remove all water. If the pump is operating and sud-
denly no water comes out of the discharge hose, shut
off the unit immediately. The water level is probably
very low and the unit has broken 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 in water that 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.
6. Keep the inlet screen clean at all times. If the bottom
surface of the pond or waterfall 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.
