2. The UV-C lamp (26) should be replaced every season, or after 8,000 burning hours. The lamp
still burns after this period, but the UV-C radiation is minimal because the gas in the lamp is consumed.
Remove the lamp from the holder (27) and fit new lamp.
Caution: position all sealing rings (5) and (7) in the correct position during
assembly
5.C DISMANTLING AND CLEANING THE PUMP
The rotor with impeller can become fouled by lime-laden water. Lime deposits can block the pump if
cleaning is not done in time.
Check this regularly, especially in the first months of use. The degree of fouling depends entirely on
water quality.
If the motor is overloaded, the built-in motor protection will switch off the pump, it can also switch on
again after some time if the motor was too hot and has cooled down again.
If switching on and off continues, irreparable damage may occur to the engine.
1. Turn the pump housing (1) counterclockwise one turn and remove from motor (6).
2. Clean the rotor (3) under running water.
3. Clean the pump housing (1) inside under running water.
Note: check the sealing ring (4) and bearing caps (2) in the pump casing
and motor during assembly;, usually they remain wedged in casing during
disassembly.
Never operate the pump outside the water, as this may lead to irreparable
damage.

6.A CLEANING OF THE FILTER SPONGE AND FILTER MATERIAL
Cleaning of the filter sponge and filter material depends on the degree of soiling. If the capacity de-
creases, cleaning is necessary, check this with some regularity in the first months after filter installa-
tion.
1. Unscrew the fitted fountain or hose connector (22-26) from the filter, open the clips , then the
filter covercan be taken off the housing.
2. Clean filter sponges (4 & 17) under running water, never use detergents.
6.B DISMANTLING AND CLEANING THE UV-C DEVICE
Pond water flows past the quartz glass in the housing, causing (scale) deposits on the glass after some
time. UV-C light will therefore not reach the flowing water as well, reducing its effect. Periodically clean
the quartz glass together with the filter material.
Avoid direct contact with the lamp: hold UV-C lamp with a cloth
