HIGH FLOW
WATERFALL PUMP
CLEANING
Begin by ensuring that the mains power supply is disconnected before attempting any maintenance or
adjustment of the unit or the water body. Remove the unit from the water. If your unit is connected
to a filter, the filters and sponges will clog up over time. Please clean regularly (at least once a month)
to maintain maximum water flow. Failure to maintain the unit will result in a burnt out motor and other
damage.
All PondMAX high flow pumps are water cooled, if the pump becomes restricted, or blocked, it will
overheat and could cause permanent damage. When the flow starts to reduce, check and clean if
necessary.
The motor unit of the pump is encapsulated with epoxy resin and does not need lubrication. Regular
inspections, cleaning and maintenance of impeller is necessary to ensure longer life. Take note, the
centre of the impeller ceramic shaft is hollow. It is paramount that this hollow core is kept clear of any
blockage. This is a colling channel for the motor.
1. Clean the housing and pump with a suitable brush, taking care to clean off sludge, algae and debris.
2. To maintain the impeller of the pump, remove the impeller cover screws to separate the impeller cover
from the pump motor body.
3. Lift out the impeller assembly. Take care not to break ceramic shaft. The black disc behind the blades
is part of the entire impeller assembly. Clean the impeller with clean water, vinager and a suitable
brush taking note to remove fine sediment on and around the back end of the impeller. Inspect the
impeller assembly for damage or cracking and replace if necessary. Reassemble the impeller into the
motor.
4. Next replace the o-ring. This is easier to do once the impeller is in place. You can then hold the
impeller in place with one hand while using your other hand to stretch the o-ring over the plate and
into the groove.
5. Once the o-ring is in place, replace the impeller cover taking care that the o-ring stays in place. Then
reinstall the screws.
