Maintenance for the qualified
professional
If water is constantly dripping out of the safety valve, it prob-
ably requires cleaning. Before servicing the safety valve, the
inlet to the water heater must be blocked.
■ Shut off the safety valve 2.
■ Open the hot-water tap (to eliminate water pressure in
the heater).
To clean the pressure control valve
■ Unscrew the exchangeable cartridge 3.
■ Rinse the valve seat and gaskets with cold, clean water.
■ Screw the exchangeable cartridge 3 firmly back in.
■ Open the safety valve 2.
■ Check for leakage.
To clean the pressure reducing valve
■ Mark the position of the adjusting screw 4.
■ Turn the adjusting screw 4 counter-clockwise until the
turnstop is reached (to decompress the spring).
■ Unscrew the screw cap 5.
■ Use pliers to remove the cartridge 6 of the pressure
reducing valve and rinse with cold, clean water.
■ Screw the cartridge 6 back on.
■ Screw on the screw cap 5.
■ Turn the adjusting screw 4 clockwise until the original,
marked position is reached.
If water still drips from the safety valve, replace the cartridge.
