cartridges, make sure that the O-ring is cleaned and lightly greased (e.g. with Vaseline).

When using a chemical lter cartridge (5 micron chem.) it must be changed regularly (twice a year or after 150 m

ow).

High-pressure nozzles instructions

Check the spray pattern of the high-pressure nozzles regularly. If necessary, the nozzles can be unscrewed and

disassembled for cleaning. In the case of limescale deposits, cleaning may be done in a descaling bath / acetic

acid bath/ultrasonic bath. Afterwards rinse thoroughly and blow out.

If there are leaks in the O-ring seals of the nozzles, the O-rings must be replaced. If the nozzle on the nozzle body

or on the spray head is damaged by mechanical or chemical overloading, the complete nozzle must be replaced.

If nozzles drip, the spring valve may be worn out and should be replaced.

Cleaning instructions

The system must be protected as good as possible against contamination. In particular, dirt on the pump unit and

the control unit must be removed regularly. Contamination can endanger the function of the system, for example

through inadequate ventilation.

Do not clean the pump unit, control unit and other electrical components with a high-pressure cleaner. Before

cleaning with water, cover all openings which have to be protected - for safety and/or functional reasons – against

water, steam or detergent penetration. After cleaning, the covers must be completely removed.
