Use a rope to position and retrieve the pump. Do not lower or retrieve
the pump using the power lead as this may damage the cable entry
seals, causing water leaks and unsafe operation.
Do not use this product for recirculating or filtering swimming pools,
spas, etc. While these pumps are built to high safety standards, they
are not approved for installations where people will be in the water
while they are operating.
Do not pump abrasive materials. Sand and grit in the water being
pumped will accelerate wear, causing shortened pump life.
Make room for the float switch to operate. Automatic models have a
float switch to turn them on when the water level rises and turn them
off again when it has been pumped down to the safe operating level of
the pump. If the float switch is not free to rise and fall, correct pump
operation may not be possible.
Don’t run your pump dry. Non-automatic models must be switched off
manually or by way of an external float/level switch when the water
level is reduced to the top of the pump housing.
