Application
In order to ensure correct operation, a pressure of at least 0.6 bar is necessary at the
shower system.
Caution:
With sufficient power (from 19 kW or 250 kcal/min) electric or gas instantaneous
heaters are suitable.
All thermostats are adjusted in the factory at a flow pressure of 3 bar on both sides.
Should temperature deviations occur on account of special installation conditions,
the thermostat must be adapted to local conditions (see Adjustment).

Installation
Make up unions, if not yet in place.
For union fastening dimensions (cold and hot water connection), see fold-out page II
Fig. [1].
(unions can be located on the left or the right-hand wall).
The hot water supply must be connected above and the cold water supply below.
The installation dimensions for the fitting relate to the standing level of the shower
stand.
The installation height of the showers from the standing
level must be observed in order to comfortably operate
the fittings, see Fig. [1].
• Install union elbows, see Fig.[2].
(the lower union elbow must be installed approx. 20° offset).
• Drill ø6mm fixing holes for fixing brackets, see Fig. [3].
Flush pipes thoroughly
The following dismantling steps must be performed before commencing
installation of the shower system:
Remove fixing screws (B1) and detach cover (B), see Fig. [4].
Please pass these instructions on to the fitting user!

Adjusting
For temperature adjustment, see Figs. [11] and [12].
1. Open the shut-off knob (P) to the handspray position and measure the
temperature of the water running out using a thermometer, see Fig. [11].
2. With the safety stop depressed, turn thermostat knob (O) until the water
temperature reaches 38 °C.
3. Lever out cap (O1), see Fig. [12].
4. Hold thermostat knob (O) in this position and remove screw (O2).
5. Pull off thermostat knob (O) and reinstall in such a way that the mark
on the knob aligns with the 38 °C lettering on the cover (D).
6. Hold thermostat knob (O) and reinstall screw (O2).
7. Refit cap (O1).
Temperature limitation
The safety stop limits the temperature range to 38 °C. If a higher temperature is
required, the 38 °C limit can be overridden by depressing the safety stop.
