Installation to finished stage
- Plaster and tile the wall, excluding the area occupied by the
mounting template. Seal any apertures in the wall so that they
are watertight to spray water.
•
Tiles laid in mortar should be pointed so that the joint is
tapered towards the outside.
•
Seal prefabricated walls with a permanently plastic
compound.
- Remove the mounting template, and install sleeves, see fig. [1].
Flush out the pipelines.
Reversed union (hot on right - cold on left).
Replace thermoelement (G), see replacement parts fold-out
page II, ref. No.: 47 282 (1/2”).
- Unscrew and remove non-return valve (A), see fig. [2].
- Insert flushing plug (B) in vacant non-return valve aperture, see
fig. [3].
- 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).
- Secure escutcheon with screws, see Fig. [4].
If the thermostat has been installed at too great a depth, this
can be adjusted by 27.5mm with an extension set (see fold-out
page II, ref. No. 47 261).
If the thermostat has been installed at too shallow a depth, this
can be adjusted by 20mm with an compensation ring (see fold-out
page II, ref. No. 08 935 or 08 936).
Installation of the flow control knob and adjustment of the
economy stop, see Figs. [5] to [7].
•
The flow rate is limited by the economy stop (M) supplied,
see Fig. [5].
To install the flow control knob, proceed as follows:
1. Close the ceramic headpart by turning clockwise.
2. Install the economy stop (M) in the desired position, see Fig. [5].
For possible settings, see Fig. [6].
3. Install splined adapter (L) and flow control knob (K) with
economy button (N) pointing to the right.
Install screw (H) and cap (I), see Fig. [7].
If a higher flow rate is desired, the stop can be overridden by
depressing the economy button (N), see Fig. [7].
Adjustment
Installation of the thermostat knob and temperature
adjustment, see figs. [8] to [10].
•
Before the mixer is put into service if the mixed water
temperature measured at the point of discharge varies from the
specified temperature set on the thermostat.
•
After any maintenance operation on the thermoelement.
1. Open the shutt-off valve and check the temperature of the water
with a thermometer, see fig. [8].
2. Turn the adjusting nut (R) clockwise or anticlockwise until the
water temperature reaches 38
°
C, see fig. [8].
3. Install thermostat knob (C) in such a way that the 38
°
C mark on
the knob coincides with the mark (F) on the wall plate, then
tighten screw (E) securely, see fig. [9].
4. Install cap (D), see Fig. [10].
Temperature limitation
The safety stop limits the temperature range to 38
°
C.
If a higher temperature is desired, the 38
°
C stop can be overridden
by pressing in the safety stop.
Prevention of frost damage
When the domestic water system is drained, thermostat mixers
must be drained separately, since non-return valves are installed in
the hot and cold water connections.
The complete thermostat assemblies and non-return valves must
be unscrewed and removed.
