5) Maintenance & Cleaning (cont...)
5.3 Replacing foams
• After prolonged use, the filter foams may become damaged. This can be identified on
the inability of the foams to return to shape after cleaning. Replacement of the foams is
recommended.
5.4 Winter Storage
• The filter can be run year round if the pump flow is maintained. Alternatively, in winter the
filter may be switched off. Follow annual maintenance procedure and store frost-free in
the house or garage until spring.
6) Troubleshooting
In order to correctly identify if you have green water or cloudy/brown water, a settlement test
should be carried out.
Fill a glass of pond water and let it settle for few hours. When the glass is stirred, a small
layer of settled waste can be seen at the base of the glass. This indicates that you have
brown or cloudy water and that, if you have an UVC model, it is working correctly. Lack of
settlement indicates that you have green water and the UVC is not working correctly.
6.1 Filter Leaks
• Check that all o-ring seals are in place and are not damaged. Replace if necessary.
• Check that the canister clamp is correctly fitted and closed.
• Check hosetails and stainless steel hose clamp for damage.
• Teflon tape may be needed to give a water-tight hose to hose connector seal.
• Always secure with a hose clamp.
6.2 Cloudy/Brown Water
• The flow rate/pond turnover is too high or low. Check pond volume and pump flow rate. See “3.3
Connecting to your Pump.”
• The filter is not being supplied with pond water 24 hours a day. Do not turn off your pump.
Continuous running is needed to maintain a clean and healthy pond.
• Do not clean foams until the filter outlet flow is visibly reduced.
• Foam discs are blocked/damaged - follow “5.1 Routine Maintenance.” Replace foam discs.
• The water is extremely dirty - remove leaves and waste - do a partial water change.
• Filter is incorrectly sized - refer to filter performance and specification chart. Calculate pond
volume - see “3.3 Connecting to your Pump.”
• Inlet and outlet pipes are connected the wrong way round. Disconnect and reconnect using the
flow in flow out arrows on the filter.
• All foams have not been replaced or are positioned incorrectly. See foam configuration diagram.
• Outlet tube cover (7) is missing from the filter outlet tube (6). Replace with tube or block to stop
water bypassing foam. See diagram 1.
