Preliminary information
Surface mounted thermostat mixers are designed for hot
water supply via pressurized storage heater and utilized in
this way provide the best temperature accuracy. With
sufficient power (from 18 kW or 250 kcal/min) elctric or gas
instantaneous heaters are suitable.
Thermostats cannot be used in connection with low
pressure storage heaters.
All thermostats are adjusted in the plant at a flow pressure
on both sides of 3 bar.
If temperature deviations should exist due to special
installation conditions, then the thermostat is to be
adjusted to the local conditions (see Adjustment).

At a flow pressure over 5 bar it is recommended that a
pressure reducing valve be fitted in the supply line.

Installation
Flush out pipes.
These installation instructions for thermostatic mixers are
applicable both to replacements and new installations.
In the case of a new installation, special accessories must
be ordered, i.e. ref. No. 12 419, 12 400 and 12 407 for a
vertical installation or ref. No. 12 400 and 12 407 for a
horizontal installation.
For Cat. Pos., see fold-out page II.
Install S-unions and outlet elbow.
Screw-mount the mixer securely, see Fig. [2].
In this connection, refer to the dimensional drawings on
fold-out page I.
The outlet pipe (C) must be shortened to the appropriate
length.
The hot water supply must be connected on the left, the
cold water supply on the right, as viewed from the
operating position.
Thermostatic mixers are assembled at the factory for a
vertical mounting position.
0.5 bar
10 bar
If a horizontal position is required, the mixer must be
1 - 5 bar
adapted as follows, see Fig. [2].

2. Reinstall the removed components on the mixer body,
offset about one union in the anticlockwise direction.

Mixer No. 34 364 can be converted to a shower mixer by
= 5 l/min
means of the outlet nipple (G) supplied, see Fig. [3].
1. Remove union connection set (F).
2. Remove cap with screw (E) and install in aperture
requiring to be blanked off.
3. Install outlet nipple (G), supplied, in the mixer.
Test unions for leaks.
Reversed union (hot on right - cold on left).
