Installation
- Remove the mounting template, see fold-out page I fig. [1].
- Make shure the water supply is turned on at the service stop
valves (A). Stop valves must be in fully open position (slots
horizontal) for valve to function.
- Remove adapter (B) and stop ring (C).
- Turn stop ring (C) and reinstall in such way that the
mark (C1) is at right, see fig. [2].
- Install adapter (D) and fit sleeve (E).
- Grease the seal (F) for the escutcheon mounting bracket (G)
with the special grease supplied and install escutcheon
mounting bracket (G) with screws (H), see fig. [3].
- Fit the escutcheon (I).
If thermostat is installed too deep, the fitting depth
can be increased by 1 1/8" (27.5mm) with extension set
Part No. 47 820, see fold-out page II.
Adjustment
Installation of the thermostat knob and temperature
adjustment, see figs. [4] and [5].
• 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. [4].
2. Turn the adapter (D) clockwise or anticlockwise until the
water temperature reaches 100 °F (38 °C).
3. Install temperature control handle (J) in such a way that
the 100° F mark is at top, see fig. [5].
4. Fit snap insert (K) and install with screw (L).
5. Fit knob (M).
6. Screw in set screw (M1) with 2mm allen wrench supplied.
Reversed union (hot on right - cold on left).
Back-to-back installation is possible by reversing the cartridge-
holder, see technical product information for the concealed
thermostatic valve.
Temperature limitation
The safety stop limits the temperature range to 100 °F (38 °C).
If a higher temperature is desired, the 100 °F (38 °C) limit can
be overridden by depressing the button (J1), see fig. [5].
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
Inspect and clean all parts, replace if necessary and grease
with special valve grease.
I. Thermostatic compact cartridge
1. Turn temperature control handle (J) in such a way that the
100° F mark is at top, see fig. [5].
2. Unscrew and remove set screw (M1) with a 2mm allen
wrench.
3. Pull off knob (M).

4. Unscrew screw (L) and pull off snap insert (K).
5. Pull off temperature control handle (J).
6. Detach escutcheon (I) in accordance with fig. [6].
7. Remove screws (H) and escutcheon mounting bracket (G),
see fig. [3].
8. Close both service stop valves (A), see fig. [1].
9. Remove sleeve (E) and adapter (D), see fig. [2].
10. Pull off stop ring (C).
11. Remove screws (O2), screw (O1) and remove unit (O),
see fold-out page III, Fig. [7].
12. Unscrew nut (P) with 34mm wrench, see Fig. [8].
13. If necessary, lever out thermostatic compact cartridge (Q)
via recess (Q1).
14. Remove screw ring (P).
15. Pull out thermostatic compact cartridge (Q).
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (Q), see details, Fig. [8].
Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjustment).
II. Non-return valve
1. Proceed as for maintenance of the thermostatic compact
cartridge, points 1 - 11.
2. Remove the four corner screws (R1) and remove the valve
cover (R) as assembled unit with the O-ring (S1),
see Fig. [9].
3. Pull the cartridge holder (S) out of the valve body noting the
location of "H" and "C".
4. Remove the check valve inserts (T1) or (T2), see Fig. [10].
If the check valves are removed it is important to reinstall them
with the O-ring facing away from the cartridge. If they are
installed incorrectly no water will flow.
Reassemble in reverse order.
Ensure that the hot "H" and
cold "C" markings are on the correct side.
- Make sure when sliding cartridge-holder (S) into the body
that the cartridge holder fits into the positioning grooves (U)
of the body. When correctly engaged the cartridge holder
will not rotate, see Fig. [11].
- Take care not to damage inlet O-ring (V).
- If the O-ring (S1) is not on the valve cover (R) re-install and
make sure the surface of the valve cover and the O-ring (S1)
are both clean, see Fig. [9].
Seat the valve cover (R) with assembled cartridge in the
cartridge-holder (S). Do not pinch the O-ring (S1). The
assembly should fit together with a minimum of pressing force.
Install the cover screws (R1). Tighten lightly in a diagonal
pattern, then tighten firmly.
Observe the correct mounting position!

accessories).
