Adjustment of economy stop on shower mixer 34 610,
see figs. [7] and [8].
•
The flow rate is limited by a stop, preadjusted by the
factory.
If a higher flow rate is desired, this stop can be
overridden by depressing the economy
button (J).
To adjust the stop, proceed as follows:
1. Unscrew and remove cap (K).
2. With a screwdriver, release the screw inside the shutoff
knob (L).
3. Turn the shutoff knob (L) until the desired flow rate is
obtained.
4. Pull off the shutoff knob (L) and reinstall in such a way
that point (M) on the scale coincides with the mark (O1)
on the inner part of the knob (O).
Testing the automatic diverter function on
mixer 34 472, see fig. [7].
Open the shutoff valve to release the water flow.
Initially, water flows from the bath spout.
Press diverter button Transfer from bath
spout to shower outlet
Pull button Transfer from shower
outlet to bath spout
Turning off the fitting automatically diverts the water flow
from the shower outlet to the bath spout.
Prevention of frost damage
When the domestic water system is drained, thermostat
mixers must be drained 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.
