Cause
- Supply pressure inadequate
- Regulator filter dirty
- Shower filter seal dirty
- Backflow preventers dirty or leaking
- Thermostat has not been adjusted
- Hot water temperature too low
- thermo cartridge calcified
- Filters are dirty
- check valve hasn't moved back
- Flow limiter in handshower isn't removed
Assembly see page 31
Do not use silicone containing acetic acid!
Adjustment (see page 40)
After the installation, the output temperature of the thermostat must be
checked. A correction is necessary if the temperature measured at the
output differs from the temperature set on the thermostat.
Safety Function (see page 40)
The desired maximum temperature for example max. 42º C can be pre-
set thanks to the safety function.
Operation (see page 42)
Dimensions (see page 43)
Flow diagram (see page 44)
Maintenance (see page 46)
The check valves must be checked regularly according to DIN EN
1717 in accordance with national or regional regulations (at least once
a year). To guarantee the smooth running of the thermostat, it is neces-
sary from time to time to turn the thermostat from total hot to total cold.
