Temperature limitation
The safety stop limits the temperature range to 38 °C.
If a higher temperature is desired, the 38 °C limit can be
overridden by depressing the safety stop.
Prevention of frost damage
When the domestic water system is drained, thermostat
mixers must be draind separately, since non-return valves
are installed in the hot and cold water connections. For
this purpose, the mixer must be removed from the wall.
Adjusting the economy stop
For flow rate adjustment, see figs. [4] to [7]
• The flow rate is limited by a stop, adjusted by the
factory.
If a higher rate is desired, the stop can be overridden by
depressing the economy button (K), see fig. [4].
If the stop is required to be adjusted, proceed as follows:
1. Close shut-off valve.
2. Pull off or unscrew cap (L) and remove screw (M), see
fig. [4].
3. Remove shut-off knob (F), splined adapter (N) and
economy stop (P), see fig. [5].
4. Reinstall economy stop (P) in the desired position. For
adjustment range, see fig. [6].
5. Fit splined adapter (N) and shut-off knob (F) with
economy button (K) facing to the front. Reinstall
screw (M) and refit or screw on cap (L), see fig. [7].
Check function of automatic diverter (R) of bath mixer
34 357, see also fig. [8].
The water supply is turned on by lifting the lever.
The water will always emerge from the bath outlet first of
all. Pulling the changeover selector (R) closes the water
passage to the bath and the water is diverted to the
shower outlet.
When the mixer is turned off, the diverter is automatically
reset to its starting condition, with the result that the water
always flows out of the bath tap when the mixer is turned
on again.
