Overloads - Single Phase
In single-phase units, an automatic overload protector in the
motor will protect motor from burning out due to over heating/
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
overload 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.

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,

NOTICE: Whenever motor cover is being removed for
service, 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.
