FILTRATION & WATERFALL PUMPS
1. Clean the housing and pump with a suitable brush, taking care to clean off sludge, algae and debris.
2. To maintain the impellor of the pump, turn the Impellor Cover in an anti-clockwise direction as indicated by the
arrow, to the stop position. Then separate the impellor cover from the pump motor body.
3. Lift out the impellor assembly. (Take care not to break ceramic shaft.) The black disc behind the blades is part of
the entire impellor assembly. Clean the impellor with clean water and a suitable brush taking note to remove fine
sediment on and around the back end of the impellor including the small hole through the ceramic shaft if it has one.
Replace the impellor if necessary.
4. On some models, in the centre of the impellor, you may notice a small whole opening that protrudes through the
ceramic shaft from front to back. It is paramount that this portal is kept unblocked at all times. This is a cooling
channel for the motor.
5. Ensure to replace the O-Ring in the correct place shown in the picture when reassembling the unit.
IMPORTANT NOTES:
It is important to ensure that this is carried out regularly as the cooling path inside the motor will become clogged. If
the impellor assembly becomes worn or damaged it should be replaced (available from your dealer or special orders).
Failure to do so may cause serious damage to pump. Inspect for signs for wear and tear. The impellor set is a wearing
consumable part.
Once the cleaning and inspection process is completed, reassemble in the reverses manner. Reinstall the impellor into
the motor body. To place the Impellor O-Ring around the black disc successfully, firmly hold the disc with one hand, and
using the other hand stretch the O-Ring over the disc, positioning it carefully into the groove. Pay attention not to allow
the O-Ring
(4)
to roll forward, in-between the black disc and the motor body. With the impellor in the correct position,
carefully place the impellor cover back on, and then rotate clockwise back into position.
For instructions for cleaning of optional Bio-filters check the website for further information. You can help boost the
biological function of your filtration with a bacterial additive, available from your local PondMAX Dealer.
