Always disconnect
the electrical supply
before attempting to install, service,
relocate or perform any maintenance.
If the power source is out of sight, lock
and tag in the open (off) position to
prevent unexpected power application.
Failure to do so could result in fatal
electrical shock. Only qualified
electricians should repair this unit.
Improper repair could result in fatal
electrical shock.
1 . Let the pump cool for a minimum of
two hours before servicing because
the pump contains hot oil under
pressure and the motor is hot.

see troubleshooting chart.
3 . Inlet should be kept clean and free
of all foreign objects and inspect
annually. A clogged inlet will
damage pump.
4 . Pump should be checked monthly
for proper operation. Pump can be
checked for proper operation by
briefly removing pump power cord
from the back of the water sensor
plug and inserting directly into the
piping
on sensor face

on sensor face
backwards
pumping is less than 4
seconds
5 . Wipe water sensor surface regularly
cooling. This oil can be harmful to the
environment. Check the state
environmental laws before disposing
this oil.
Corrective Action
1. If blown, replace with proper sized fuse or reset breaker
2. If voltage is under 108 volts, check wiring size
3. Replace pump
4. If impeller will not turn, remove housing and remove
blockage
1. Install or replace check valve
2. Position pump switch away from the inlet so switch is clear
from incoming water (see Figure 1)
1. Remove pump and clean pump and piping
2. If voltage is under 108 volts, check wiring size
3. Install pump on dedicated circuit. IMPORTANT: Do not use
extension cord to power pump.
4. Clean sensor face (see Figure 2)
5. Position pump switch away from the inlet so switch is clear
from incoming water (see Figure 1)
1. Clean out impeller
2. Reverse position of check valve
3. Drill 1/8" hole in discharge line between pump and check
valve
1. Wipe off surface of sensor (see Figure 2)
2. Additional run time will not damage pump

grounded outlet. In this condition,
the pump will run continuously.
Once pump operation is verified,
replace pump power cord into the
back of the water sensor plug (see
Figure 2).
to prevent silt or other coatings
from building up on sensor face
