Application
Thermostat mixers are designed for hot water supplies
from pressurized storage heaters and offer the highest
temperature accuray when used in this way. Given
sufficient output (min. 18 kW or 250 kcal per min), electric
or gas- fired instantaneous heaters are also suitable.
Thermostats cannot be used in conjunction with
unpressurized storage heaters (displacement water
heaters).
All thermostats mixers are adjusted at the factory with a
flow pressure of 3 bar on both sides.
If temperature deviations should occur on account of
special installation conditions, the thermostat should be
adjusted to local conditions (see Adjustment).

Installation
Flush pipe lines thoroughly
Install mixer securely, see fig. [1].
In this connection, refer to the dimensional drawings on
fold out page I. The hot water supply must be connected
on the left, the cold water supply on the right, as viewed
from the operating position.
The projection can be increased by 18 mm with an
extension, see fold-out page I (ref. No. 07 130).
Check connections for leaks.
Reversed union (hot on right - cold on left).
Replace thermoelement (Z), see replacement parts
fold-out page I, ref. No.: 47 282 (1/2").
Adjustment
For temperature-adjustment, see figs. [2] and [3]
• Before the mixer is put into service if the mixed water
temperature measured at the point of discharge varies
from the specifiede temperature set on the thermostat.
0.5 bar
• After any maintenance operation on the thermoelement.
1 bar
10 bar
Open the shutt-off valve and check the temperature of the
1 - 5 bar
water with a thermometer, see fig. [2].
16 bar
With the safety stop depressed, turn thermostat knob (E)
approx. 20 l/min.
until the water temperature reaches 38 °C.
approx. 27 l/min.
80 °C
- Hold thermostat knob (E) in this position and unscrew
60 °C
and remove screw (G).
38 °C
- Pull off thermostat knob (E) and reinstall in such a way
that the 38 °C mark on the knob coincides with the mark
(W) on the mixer body, see fig. [3].
left
- Hold thermostat knob (E) and reinstall screw (G), see
right
fig. [3].
= 5 l/min
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.
Temperature limit stoper for 45 °C for additional
assembly available under ref. No. 05657, see fold-out
page I.
