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, see fig. [1].
- Unscrew adjusting nut (A). Detach stop ring (B), see fig. [1] and
fold-out page II.
- Install sleeve (C), remove stop ring (B) and fit stop ring (D)
provided with marking facing upwards, see figs. [1] and [2].
- Install adjusting nut (A) and fit snap insert (Q1) with screw and
spring (R1), see fig. [2].
- Install holder (G), screw-mount sleeve (H) and secure with screw
ring (I), see fig. [3].
- Grease the seals (J) for the escutcheon mounting bracket (K)
with the special grease supplied and install escutcheon mounting
bracket (K) with lever mounting assembly (L), see fig. [4].
- Fit the escutcheon (M), 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. 47 358).
Reversed union (hot on right - cold on left).
Replace thermoelement (A1), see replacement parts
fold-out page II, ref. No.: 47 282 (1/2”).
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 (N) 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 (N) in the desired position, see fig. [5].
For possible settings, see fig. [6].
- Fit sleeve (O) so that the mark PULL is at top, see fig. [7].
- Fit splined adapter (P) with snap insert (Q2) and screw with
spring (R2), see fig. [7].
- Install flow control knob (S) in such a way that the mark
coincides with the mark PULL on the sleeve (O), see fig. [7].
If a higher rate is desired, the stop can be overridden by pulling the
flow control knob (S).
Adjustment
Installation of the thermostat knob and temperature
adjustment, see figs. [8] and [9].
•
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 (A) clockwise or anticlockwise until the
water temperature reaches 38
°
C, see fig. [8].
3. Fit scale ring (T) so that the mark PULL
is at top, see fig. [9].
4. Install temperature control handle (U) in such a way that the
mark
coincides with the mark PULL
on the scale ring (T),
see fig. [9].
Temperature limitation
The safety stop limits the temperature range to 38
°
C.
If a higher temperature is desired, the 38
°
C limit can be overridden
by pulling the temperature control handle.
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.
Maintenance
For maintenance, see fold-out page II and fig. [10].
Shut off hot and cold water supplies.

3. Pull off stop ring (D).
4. With a 24mm open-ended spanner, unscrew and remove
thermoelement (A1).
II. Non-return valve
1. Pull off temperature control handle (U) and flow control knob (S).
2. Detach escutcheon (M) in accordance with fig. [10].
3. Remove screws (V) and escutcheon mounting bracket (K).
4. Unscrew and remove non-return valve (E1) with 17mm socket
wrench.
III. Ceramic headpart
1. Proceed as for maintenance of non-return valve, points 1-3.
2. Remove screw (X), pull off spring (Z) and snap insert (Q2).
3. Remove splined adapter (P), sleeve (O) and economy stop (N).
