Overloads - Single Phase
In single-phase units, an automatic overload protector in the
motor will protect motor from burning out due to overheating/
overloading. When motor cools down, protector automatically
resets 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.

overload setting.
For pumps with a nameplate service factor of 1.0, set over-
load protective device to nameplate full load current.
For pumps with a nameplate service factor of 1.15 or higher,
set overload protective device to 1.09 times the nameplate
full load current.
Size overload protective device so that trip current is 115% of
final setting as selected above.

CORD LIFT WARNING
SERVICE
Pump is permanently lubricated. No oiling or greasing is
required in normal service.
NOTICE: Do not allow pump to run in a dry sump. It will void
the warranty and may damage the pump.
Hazardous voltage. Can shock, burn, or
cause death. Before servicing pump, disconnect electrical
power to pump and control switch.
After removing basin cover and necessary discharge piping,
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 thoroughly.
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 cover is being removed for ser-
vice, remove oil and replace with new oil at reassembly. 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 1/4" (6 mm) above
top of motor assembly.
1. Attempting to lift or support pump by
power cord can damage cord and cord
connections.
2. Cord may pull apart, exposing bare wires
with possibility of fire or electrical shock.
3. Lifting or supporting pump by power cord
will void warranty.
4. Use lifting ring or handle on top of pump
