OPERATION
The water level switch is activated by a float mechanism. This is
caused by water rising around the float with the pump resting
upright. This switch relies upon buoyancy force of the float to
activate. The switch should cause pump to come on when the
water level is approximately 2"-3" deep. Pump should remain
running until the water level is approximately .50"-1.50" deep.
NOTE: Temperatures near freezing may cause the ON level to go
as high as 4", and the OFF to be as high as 2".
ELECTRICAL CONNECTIONS
1. Your pump is supplied with a 3-prong electrical plug. The third
prong grounds the pump to prevent possible electrical shock
hazard. Do not remove the third prong from the plug.
2. A separate branch electrical circuit is recommended. The
electrical power required is 5 amp at 115 VAC.
3. Be sure that electrical connection cannot be reached by rising
water. Under no circumstances should the connection be located
where it may become flooded or submerged by water.
4. Test the pump after all electrical connections have been made.
Run water into area where pump is to be placed. Do not attempt
to run the pump without water; this could cause damage to the
pump. Fill the area to a normal ON level and allow the pump to
remove water to a normal OFF level.
WARNING: Always disconnect the electrical power before touching
the pump, discharge, or electrical plug when water is present in
the area. Failure to do so can result in serious bodily injury and/
or property damage. Always connect the pump to a grounded
receptacle. See SAFETY GUIDELINES.
SERVICE INSTRUCTIONS
Before servicing pump, disconnect it from electrical service, unplug
cord, remove fuse, or turn off disconnect box.
The motor housing of the pump is completely sealed and requires
no service. Disassembly of the motor housing or alteration of the
power cord voids all warranty.
The motor is a continuous duty type with an automatic thermal
overload protector device.
The pump can run against a restricted discharge without damage
to the pump.
Keep pump clean and in a well maintained condition at all times.
Pump should be thoroughly cleaned for summer storage.
If float becomes stuck, remove the float access cap on the bottom
of the pump. Remove cap by turning towards the “OPEN” arrow as
indicated on the cap. Clean as needed, then reinstall access cap.
This pump has an internal vent hole to prevent an air-lock condition.
Periodically the vent hole can become obstructed and will require
cleaning according to Figure 1 and the following steps:
1. Disconnect the pump from electrical service.
2. Loosen and remove the five screws from the outer blue cover.
(NOTE: Only four of the five screws are shown in Figure 1.)
3. Remove the outer cover.
4. Clean debris from the vent hole.
5. Re-install the outer cover and screws.
6. Re-connect the pump to electrical service.
