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).
Specifications
Minimum flow pressure without
downstream resistances
Minimum flow pressure with
downstream resistances
Max. working pressure
Recommended flow pressure
Test pressure
Flow rate at 3 bar flow pessure
Max. water temperature at hot water inlet
Recommended max. stored temperature (energy saving)
Safety check
Hot water temperature at supply connection
min. 2 °C higher than mixed water temperature
Hot water connection
Cold water connection
Minimum flow rate
At a flow pressure over 5 bar it is recommended that a pressure
reducing valve be fitted in the supply line.
Installation
Flush pipe lines thoroughly.
The hot water supply must be connected on the left and the cold
water supply on the right as viewed from the operating position.
Connect unions as described in enclosed installation instruction for
Easy-fix unions (part no. 12 088).
Push on the mixer against the wall.
Refer to the dimensional drawing on fold-out page I.
Tighten set srew (A) on hot and cold water supply
side using 3mm socket spanner and insert plug (B), see
fold-out page I, fig. [1].
Open hot and cold-water supply and check connections for
leakage!
Adjustment
For temperature-adjustment, see figs. [2] and [3].
• 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 thermostatic cartridge.
Open the shutt-off valve and check the temperature of the water
with a thermometer, see fig. [2].
Pull off temperature control handle (C).
Turn adjusting nut (D) until the water temperature reaches 38 °C,
see fig. [3].
Reinstall temperature control handle (C) in such a way that the
mark (C1) on the temperature control handle (C) coincides with
the 38° mark on the scale ring (E), see fig. [2].
Reversed union (hot on right - cold on left).
Replace thermoelement (Z), see replacement parts fold-out page II,
ref. No. 47 282 (1/2").
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 depressing the safety stop (I).
Flow control knob (F) operation, see fold-out page III, [5].
Spout = Turn the flow control knob
Shower = Press button (H) and turn the flow control knob
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. For this purpose, the mixer
must be removed from the wall.
Maintenance
For maintenance, see fold-out page II and figs. [1], [4], [5] and [6].
Inspect and clean all parts, replace if necessary and grease with
special valve grease (ref. No. 18 012).
0.5 bar
Shut off hot and cold water supplies.
1 bar
I. Non-return valve, see fold-out page II.
10 bar
1. Disassemble mixer in reverse order, see fold-out page I fig. [1].
1 - 5 bar
2. Remove dirt strainer (N).
16 bar
3. Remove circlip (O1) and non-return valve (O2).
approx. 20 l/min.
4. Unscrew shower hose and detach non-return valve (O).
80 °C
60 °C
Reassemble in reverse order.
38 °C
II. Thermostatic cartridge, see fold-out page II.
1. Pull off temperature control handle (C).
left
2. Pull off scale ring (E).
right
3. Unscrew and remove adjusting nut (D).
= 5 l/min
4. Pull off stop ring (S).
5. Unscrew and remove thermostatic cartridge (Z) with a 24mm
open-ended spanner.
Reassemble in reverse order.
Observe the correct installation position of the stop ring.
Readjustment is necessary after every maintenance operation on
the thermostatic cartridge (see Adjustment).
III.Aquadimmer, see fig. [5].
1. Remove shut-off knob (F).
2. Remove sleeve (J).
3. Remove screw (G) and snap insert (M).
3. Take off stop (L).
4. With a 19mm open-ended spanner, unscrew and remove
aquadimmer (Q).
Reassemble in reverse order.
Observe the correct installation position, see fig. [4], [5] and [6].
1. The various pins (R) and (R1) must project into the relevant
apertures in the race, see fig. [4].
2. Fit stop (L) so that the pin (K) project into the aperture (T) in the
housing, see fig. [5].
3. Turn isolating valve of the aquadimmer so that face (P) points to
the front, see fig. [6].
4. Fit snap insert (M) so that the faces (P) coincide, see fig. [6].
5. Fit sleeve (J) so that the marking (K1) at the stop (L) aligned with
the dot on sleeve (J), see fig. [5].
6. Reinstall flow control knob (F) in such a way that the mark (F1)
coincides with the mark dot on the sleeve (J), see fig. [5].
IV. Aerator (13 927) see fold-out page II.
Unscrew aerator and clean.
Reassemble in reverse order.
Replacement parts, see fold-out page II ( * = special accessories).
