2. With the cover uninstalled, add
water to the basin and observe the
float control switch operation.
3. Also, test alarm switch if installed.
4. Secure and seal basin cover.
Do not run your pump in a dry sump.
Do not attempt to oil the motor. A special
oil has been put in the motor housing at
the factory. Use of any other oil could
damage the pump and WILL void the
warranty.
Maintenance
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.
Operation
Always disconnect the power
source before attempting to
install, service, relocate or
maintain the pump. Never touch sump
pump, pump motor, water or discharge
piping when pump is connected to
electrical power. Never handle a pump
or pump motor with wet hands or when
standing on wet or damp surface or in
water. Fatal electrical shock could occur.
1. Verify pump and switch operate
within the basin.
Risk of electrical shock! This pump is
supplied with a grounding conductor
and grounding type attachment plug.
Use a grounded receptacle to reduce
the risk of fatal electrical shock.
Never cut off the round grounding
prong. Cutting the cord or plug will
void the warranty and make the pump
inoperable.
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.
2. Disassembly of the motor prior to
expiration of warranty will void the
warranty. If repairs are required,
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.
This pump contains dielectric oil for
cooling. This oil can be harmful to the
environment. Check the state
environmental laws before disposing
this oil.
