OPERATION
NOTICE: Do not allow 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 pro-
tect motor from burning out due to overheating/overload-
ing. When motor cools down, overload protector will
automatically reset and start motor.
If overload trips frequently, check for cause. It could be a
stuck impeller, wrong/low voltage, or electrical failure in
motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.
Pump is permanently lubricated. No oiling or greasing is
required.
SERVICE
Pump is permanently lubricated. No oiling or greasing is
required in normal service.
Hazardous voltage. Can shock, burn, or
cause death. Before servicing pump, disconnect electri-
cal power to pump and control switch.
After removing basin cover and necessary discharge pip-
ing, lift pump out of basin.
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. (See "Cord Lift
Warning").
Place pump in an area where it can be cleaned thor-
oughly. Remove all scale and deposits on pump.
Submerge pump in disinfectant (chlorox or chlorine) for
at least one hour before disassembling pump.
The pump motor housing contains a special lubricating
oil. Keep oil clean and free of water at all times.
NOTICE: Whenever motor housing is being removed for
service, remove oil and replace with new oil at reassem-
bly. Use only oil listed in parts list (Part No. U197-8A).
When filling with new oil, DO NOT overfill. To allow
room for expansion, oil level with cold motor should be
about 6 mm (1/4") above top of motor assembly.
Impeller, Seal, and Capacitor Replacement
Risk of electrical shock. Disconnect
electrical power from pump before doing any service
work on it!
Numbers refer to assembly drawing, Page 7.
