Application
Surface mounted thermostatic 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) electric 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).

Installation
Flush pipe lines thoroughly
Install S-unions and screw-mount the mixer,
see fig. [1].
In this connection, refer to the dimensional drawing.
The hot water supply must be connected on the left
and the cold water supply on the right as viewed from
the operating position.
1. Install the S-unions and sleeve, preassembled with
the escutcheon.
2. Screw-mount the mixer and test the unions for
leaks.
3. Push the sleeve with escutcheon onto the union nut.
4. Screw the escutcheon flush against the wall.
The projection can be increased by 30mm with an
extension,see Replacement Parts, fold-out page II,
ref. No. 46 238.
Fit swivel spout.
Swivel range adjustable by means of stop (C),
see fig.[2].
Fit elbow lever, see fig.[3]

= 5 l/min
Turn the temperature control handle (B) until the water
running out reaches 30 °C, see fig. [4].
- Remove screw (E) and pull off knob top plates (F),
see fig. [5].
- Remove screw (G) and pull off thermostat knob (H),
see fig. [5].
- Pull off thermostat knob (H) and reinstall in such a
way that the 30 °C mark on the knob coincides with
the mark (Q) on the mixer body and reinstal
screw (G), see fig. [5].
- Screw-mount knob top plate (F) and secure with
screw (E), see fig. [5].
Reversed union (hot on right - cold on left).
