Operation
Risk of fire and explosion. Can cause
severe injury, property damage or death. Do not use in
explosive atmospheres. Pump water only with this pump.
NOTICE Do not allow the pump to run in a dry sump. It
will void the warranty and may damage the pump.
An automatic overload protector in the motor will
protect the motor from burning out due to overheating/
overloading. When the motor cools down, the overload
protector will automatically reset and start the motor.
If the overload trips frequently, check for the cause.
It could be a stuck impeller, wrong/low voltage, or
an electrical failure in the motor. If an electrical
failure in the motor is suspected, have it serviced by a
competent repairman.
The pump is permanently lubricated. No oiling or
greasing is required.

Maintenance
General
Risk of electric shock. Can shock, burn
or kill. Before removing the pump from the basin for
service, always disconnect electrical power to the pump
and the control switch. Do not lift the pump by the
power cord. See Cord Lift Warning.
After removing the basin cover and the necessary
discharge piping, lift the pump out of the basin.
Place the pump in an area where it can be cleaned
thoroughly. Remove all scale and deposits on the pump.
Submerge the complete pump in a disinfectant solution
(dilute chlorine bleach) for at least one hour before
disassembling the pump.
The pump motor housing contains a special lubricating
oil which should be kept clean and free of water at
all times.
NOTICE Whenever the motor housing is being removed
for service, remove oil and replace it with new oil at
reassembly. Use only oil listed in parts list in this manual.
When filling with new oil, DO NOT overfill. Allow about
7/8" (22mm) air space from top of boss in housing for
expansion of oil when the pump is operating.
