▶
Always ensure absolute cleanliness when working at the valve.
Solvents and aggressive cleaning agents!
Aggressive cleaning agents may damage the seals and the surface of the valve and
let them age faster.

If a high-pressure washer is used, humidity may enter the control motor underneath
the valve cap and damage the valve.

▶
Close all openings with appropriate protective caps/devices.
▶
Ensure that all seals and electrical connections are firmly attached so that
no humidity can penetrate the valve during cleaning.
