2. Before using the pump on proposed jobsite, perform the following
environmental checks:
a. Check that available electrical socket conforms to local
codes.
b. Inspect the entire work area for unexpected buried hazards,
such as rocks, pins, nails and other obstructions that can be
sucked into the pump. The pump can malfunction as a
result, and electrical shocks, leakage and other accidents
can occur.
c. Make sure that the pump is not being placed on a loose
or soft platform where the unit can sink or suck up material
excessively, blocking water flow to the impeller.
d. Make sure that the pump will be running in water.
NEVER RUN PUMP DRY.
Doing so may result in damage to the pump, electrical
short and/or damage to seal and will void
manufacturer's warranty.
e. DO NOT SUBMERGE PUMP DEEPER THAN 26' (8m) or
the length of the supplied electrical cable, whichever is
SHORTER.
f.
Ascertain that the discharge end of the discharge hose
will be located above the water surface. If this end is
submerged, water may backflow into the pump when power
is discontinued. The end should be free from any
obstructions that can prevent smooth discharge of water.
g. Ensure that the temperature of the water that the pump is to
work in does not exceed 110ºF, or approximately 40ºC.
If any of the above checks fail, please DO NOT operate
the pump
