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.
In this connection, refer to the dimensional drawing.
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].
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 coincides with the mark PULL
fig. [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 pulling the temperature control handle (C).
Adjusting the economy stop
For flow rate adjustment, see figs. [4] and [5].
• The flow rate is limited by a stop, adjusted by the factory.
If a higher rate is desired, the stop can be overridden by pulling
the shut-off knob (F).
If the stop is required to be adjusted, proceed as follows:
1. Close shut-off valve.
2. Detach flow control knob (F).
3. Remove screw (G), detach spring (G1) and snap insert (M).
4. Remove splined insert (H) and sleeve (J), unscrew retaining
bush (K) and take off stop ring (L).
5. Fit stop ring (L) in the desired position, see fig. [5] for possible
adjustment range.
6. Screw on retaining bush (K), fit sleeve (J) with the word PULL
facing upwards. Install splined insert (H) and snap insert (M) with
screw (G) and spring (G1) and refit flow control knob (F) with
the
sleeve (J), see Fig. [4].
0.5 bar
Prevention of frost damage
1 bar
When the domestic water system is drained, thermostat mixers
10 bar
must be draind separately, since non-return valves are installed in
1 - 5 bar
the hot and cold water connections. For this purpose, the mixer
16 bar
must be removed from the wall.

For maintenance, see fig. [1], [4] and [6] and fold-out page II.
Shut off hot and cold water supplies.

I. Non-return valve
= 5 l/min
1. Disassemble mixer in reverse order, see fig. [1].
2. Remove dirt strainer (N).
3. Remove circlip (O1) and non-return valve (O).
II. Thermostatic cartridge, see fig. [6].
1. Pull off temperature control handle (C).
2. Pull off scale ring (E).
3. Unscrew and remove adjusting nut (D).
4. Remove clip (R).
5. Pull off stop ring (S) and splined adapter (T).
6. With a 22mm open-ended spanner, unscrew and remove
thermostatic cartridge (Z).
Readjustment is necessary after every maintenance operation on
the thermostatic cartridge (see Adjustment).
III.Ceramic headpart, see fig. [4].
1. Remove shut-off knob (F).
2. Remove screw (G), detach spring (G1) and snap insert (M).
3. Remove splined insert (H) and sleeve (J), unscrew retaining
bush (K) and take off stop ring (L).
4. With a 17mm open-ended spanner, unscrew and remove
ceramic headpart (Q).
Inspect and clean all parts, replace if necessary and grease with
special valve grease (ref. No. 18 012).
Reassemble in the reverse order.
Observe the correct mounting position!
Replacement parts, see fold-out page II ( * = special accessories).
Use only genuine Grohe replacement parts.
