4.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 the
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 pump housing (1) counterclockwise one turn and remove from motor (6)
2. Rotor (3) clean under running water.
3. Clean pump housing (1) inside under running water.
Note: check the sealing ring (4) and bearing caps (2) in pump casing and
motor during assembly, usually they remain wedged in the casing during
disassembly.

5.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 (1-7) from the filter, open the clips, then the filter
cover (13) can be taken off the housing.
2. Take the filter sponge (11-12) and clean under running water, never use detergents for this.
3. Open the filter housing (13) with clips, clean the pump as described under section 3.C. Clean the
filter material16 under running water.
5.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
The UV-C lamp with quartz glass (23-27) can be removed from the housing very easily by turning it
once to the left.
1. Clean the quartz glass; unscrew the swivel (25) and remove the glass from the housing (23). Do
not use detergents, clean glass with a cloth or soft brush under running water. Dry the glass well on
the inside and reassemble.
