Application
Thermostatic mixers are designed for hot water supplies
from pressurized storage heaters and offer the highest
temperature accuracy when used in this way. Given
sufficient output (min. 18 kW or 250 kcal per min),
electrical or gasflow instantaneous heaters are also
suitable.
All thermostatic mixers are adjusted at the factory to a flow
pressure of 3 bar on both sides.
If temperature deviations occur as a result of unusual
installation conditions, the thermostat should be
readjusted to suit local conditions (see adjustment).

resistances

Cold supply temperature
Recommended max. flow temperature
(for energy saving)
Hot water temperatures at supply inlet min. 2 °C higher
than mixed water temperature.
Hot water connection - W - (-H-)
Cold water connection - K - (-C-)
Minimum flow rate 5 l per min
At flow pressures above 5 bar, we recommend installing a
pressure reducer in the supply pipe.
Installation
Thermostat connected to pipe lines, see fig.[1].
- Do not solder the connections between the pipe
lines and housing, otherwise the built-in non-return
valves may be damaged.
- Connecting the pipe lines to the thermostat is
facilitated on the cold water side by using the left/right
threaded nipple, supplied loose, see fig. [2].
- Seal the open outlet with a screw plug.

Note!
- The hot water supply must be connected on the left
(marked W (H) on housing) and the cold water supply
on the right (marked K (C) on housing), as viewed
from the operating posi-tion.
Checking pipes and thermostatic mixer body for
leaks.
- Unscrew and remove non-return valve (A), see fig. [3].
- Insert flushing plug (B) in vacant non-return valve
aperture, see fig. [4].
- Open the hot and cold water supplies and flush out the
thermostatic mixer thoroughly.
- Close the hot and cold water supplies, remove plug (B)
and install non-return valve (A).

temperature measured at the point of discharge varies
52 - 65 °C
from the specified temperature set with the thermostat.
5 - 20 °C
• After any maintenance operation on the thermoelement.
60 °C
Open tap and measure temperature of water flowing out
with thermometer, see figs. [4] and [5].

Turn the temperature control handle (X) until the water
right
running out reaches 30 °C, see fig. [5].
= 5 l/min
- Remove screw (E) and pull off knob top plates (F),
see fig. [6].
- Remove screw (G) and pull off thermostat knob (H),
see fig. [6].
- Pull off thermostat knob (H) and reinstall in such a way
that the 30 °C mark on the knob is allined to the top and
reinstal screw (G), see fig. [6].
- Screw-mount knob top plate (F) and secure with
screw (E), see fig. [6].
