Safety Notes
Gloves should be worn during installation to prevent
crushing and cutting injuries.
Do not use silicone containing acetic acid!
Assembly (see page 3)
Attention! The fitting must be installed, flushed and
tested after the valid norms.
Adjustment
Correction is necessary if the temperature measured at
the take off point differs from the temperature set on the
scale. To adjust temperature proceed as follows:
Turn the setting knob until water at a temperature of 38°
C comes out of the outlet. Loosen screw of setting knob.
Remove setting knob and turn to the 38° C position.
Attach setting knob again and tighten the screw (please
see page 36).
Temperature limitation
The temperature is limited by the safety check to 38°
C (100° F). If a higher temperature is required, it is
possible to override the safety stop by depressing the
safety button.
Safety Function
The desired maximum temperature for example max.
42° C can be pre-set thanks to the safety function
(please see page 36).
Fault
Insufficient water
Crossflow, hot water being forced
into cold water pipe, or vice versa,
when mixer is closed
Spout temperature does not
correspond with temperature set
Temperature regulation not possible - Temperature regulator dirty or
Safety stop button not operating

Maintenance
There is no special maintenance for thermostats. The non
return valves (94074000) must be checked regularly
according to DIN EN 1717 in accordance with national
or regional regulations (at least once a year). At this
time, please also check the filter (7.1) situated on the
MTC-thermo-element (94282000). After assembling the
MTC-thermo-element, it is necessary to check the water
temperature at the take off point as described under the
headline „adjustment". Before the adjustment, please
check, if the warm water supply is activated
and the maximum temperature of the warm water is
available at the take off point.
To guarantee the smooth running of the thermostat, it is
necessary from time to time to turn the thermostat from
total hot to total cold.
Spare parts (see page 2)
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
calcified
- For new installations: basic body
incorrectly connected (should be:
cold right, hot left) or installed with
180 rotation
- Spring defective
- Button calcified
approx. 43 l/min
Remedy
- Check water pressure (If a pump
has been installed check to see if
the pump is working).
- Clean filters
- Clean filter seal between shower
and hose
- Clean backflow preventers,
exchange if necessary
- Adjust thermostat
- Increase hot water temperature to
42 C to 65 C
- Clean temperature regulator,
exchange if necessary
- Install function block turned through
180
- Clean spring and/or button,
exchange if necessary
