attempting to lift the pump.
•
The pump should not be operated without the proper safety
devices in place. If such devices are removed during service
and repair work, make sure they are replaced before
operating the pump again.
•
Do not operate the pump when holding the cable assembly.
•
Blocking or restricting the discharge hose may cause it to
whip under the pressure.
•
Do not remove the drain plugs or valves if the pump is
operating.
•
The pump should be isolated from a pressurized system
before it is removed.
•
Allow pumps time to cool sufficiently before handling or
servicing them as heat and pressure build up inside during
operation.
•
Never apply heat in disassembling a pump as doing so could
cause an explosion.
•
Do not exceed manufacturer’s recommendation for maximum
performance, as doing so could cause the motor to overheat.
•
If the discharge valve is closed, do not continue operating the
pump, the extreme heat from doing so can cause steam to
build up creating a dangerous pressure situation. A
temperature or pressure relief valve should be installed on
the pump body.
CAUTION.
If operating the pump with a plug-in type power cord, it
should have a ground fault circuit breaker.
CAUTION.
The pumps are not recommended for: Pumping flammable
liquids, for use in areas considered dangerous; for use in
pools or water recreation facilities, for umping liquids with abrasive
solids or operating above the recommended submergence level.
The use of these pumps in the cases mentioned will cause the loss
of your warranty.
