Centrifugal multi stage 3 impeller design for low flow applications
In built automatic thermal overload to protect the motor in the event of blockage or voltage supply problems
HO7RNF oil resistant leads , 10 meters long with 3 pin power plug for longer life in dirty water and easy connection to the mains power supply.
Priming & Operation
- 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. - Don’t 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. - Don’t pump abrasive materials. Sand and grit in the water being
pumped will accelerate wear, causing shortened pump life. - Keep your pump clean, particularly in situations where lint, hair
or fibrous materials may get bound around the pump shaft.
Inspection every 6 months and cleaning will extend 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.
