Maintenance and cleaning

Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
• Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the
water.
• Isolate the unit before starting any work.
• Secure the unit to prevent unintentional switching on.
Adhere to the safety information given above! Check and clean the water outlet into the pond at regular intervals.
When blocked, danger of an operating pressure of more than 0.2 bar. We recommend to clean the foam filters at
regular intervals (e.g. every two weeks), at the latest when the water emerging from the outlet and returned to the pond
is cloudy or dirty (check soiling at the transparent stepped hose nozzle with the green flow indicator flap at the water
outlet).
Cleaning of the filter foams with the handle function
Remove the cover cap at the cleaning connection or at the connected drain hose. Slightly pull up the function switch
and set against the stop to „Cleaning" by turning counter-clockwise. Vigorously pull at the cleaning handle and "pump"
several times; in this manner the foam filters are mechanically cleaned. Push the cleaning handle down to the stop on
the cover (the two O rings tangibly engage). The filter will now be rinsed clean. As soon as only clean water is visible in
the transparent stepped hose nozzle at the cleaning connection, pull the function switch slightly up and set against the
stop to „Filter" by turning counter-clockwise. Firmly screw on the cover cap with the flat sealing ring inserted. Check the
water flow into the pond at the green flow indicator flap at the water outlet.
Cleaning the foam filters by washing out
If necessary, wash out or replace the foam filters. Do not use chemical cleaning agents. Disconnect the power supply,
switch off the pump and secure against unintentional switching on again. Disconnect all hoses by turning off the union
nuts, remove the clamping ring. For this purpose, pull the safety latch back, push the closing hook inwards, and open
the clamping ring. Remove the lid including the foam filter package, turn upside down and place on a clean surface
ensuring that the foam filters including the filter disk are facing up. The foam filters could collapse as a result of me-
chanical stress and normal ageing. Replace the foam filters if they rest on the bottom filter disk without gaps and when
the wear mark of the top disk is full visible (7). Unscrew the top filter disk by removing the two screws, pull off foam
filters and clean thoroughly in a bucket of pond water by vigorously compressing. Remove the bottom filter disk, thor-
oughly spray clean container, lid with meshed tube, both filter disks and clamping ring. Lift off the bypass valve and
clean the comb of the UVC (9). Push a filter disk including collar and the cleaning rods upward and onto the meshed
tube, alternately fit foam filters (starting with a large blue foam filter, followed by a small red foam filter) such that the
cleaning rods lie in both cut-outs of the large cavity in the foam filters. Place the filter disk with the collar facing down
and screw fit flush with the cleaning rods using the two screws. Important: When the cleaning rods can be pushed
through the holes in the filter disk, turn the filter disk through 90° to the other hole pattern. Ensure that the meshed tube
fits completely in the collar diameter. Place the cover sealing ring on the upper container rim (10), press the lid includ-
ing the foam filter package onto the container. Place the clamping ring on the container and cover rim (do not pinch the
power cable!), press on the cover, allow the closure to engage, push in the safety latch (8). Reconnect the hoses, start
up the pump first, then connect the power supply of the unit.
Cleaning the quartz glass tube
Adhere to the safety information given above! Disconnect the power supply, switch off the pump and secure against
unintentional switching on again. Undo the four screws of the UVC unit and carefully pull out of the filter cover (11),
clean the quartz glass using a moist cloth, pull out the flat sealing ring and the protection tube (12) and clean with
water.
