Application
The modular thermostatic valve is designed for use with hot
water supplied from pressurized storage heaters and offer the
highest temperature accuracy when used in this way.
The modular thermostatic valve cannot be used in conjunction
with low-pressure storage heaters (displacement water
heaters).
• Do not loose the adaptor (C) mounted on the fitting
template. You need this adaptor and the fastening set (C1)
(keep in the bag) for a few trims, see page 2.
• The adaptor (A) and the stop ring (B) are pre-mounted on
the valve. These parts will be used for several trims too, see
page 2.
• The valve is delivered as 4-port configuration.
You can switch off to 3-port (shower only) if you unscrew
nut (D) and remove connection nipple (C). The parts for
closing the outlet are not in the scope of delivery.
• Please be careful that this instruction is present for the final
installation- you can have different rough in valves with
different installtion steps!
Specification
• Concealed single handle thermostatic valve
• Integral service stops
• Integral check valves prevent cross flow
• Thermostatic cartridge automatically adjusts to inlet
temperature and pressure fluctuations
• Cartridge restricts hot water supply should the cold pressure
fail, to prevent scalding
• Flow pressure:
- min
- recommended
greater than 72.5 psi, fit pressure reducing valve
• Max. operating pressure
• Max. test pressure
• Flow rate at 45 psi flow pressure
• Temperature
- max. (hot water inlet)
• Back-to-back installation is possible by reversing the
cartridge-holder.
(see back-to-back installation instructions)
• Water connection:
Rough-in installation
1. Prepare wall for rough-in valve.
2. Observe the installation depth in accordance with the
instructions given on the fitting template, see fig. [1] and [4].
U = Face of tiles
T = Front face of fitting template
S = Resting point for spirit level
3. Align the mixer horizontally, vertically and parallel to the wall,
see fig. [5] (place a spirit level on the cams or face of the
fitting template).
4. Install concealed thermostatic valve in the wall and connect
pipes.
Permissible tolerances are given in the dimensional
drawing, see page 1.

IMPORTANT
A shut-off device must be installed after the mixed water outlet
of concealed thermostatic valve.
It is not necessary to remove the cartridge from the valve
during normal soldering connection.
When soldering CxC connections, do not use excessive heat.
This valve has no by-pass annulus and therefore when
used with diverter spout a twin ell must be used and the
top outlet plugged.
Check connections for leakage.
Flush piping system prior and after installation of faucet
thoroughly!
Back-to-back installation
1. Identify valve with hot/cold reversed supply.
2. Remove adaptor (C), see Fig. [1].
3. Unscrew nut (G) to remove finish wall template (H), see
Fig. [6].
4. Remove the adaptor (A), see Fig. [2].
5. Remove screws (J), screw (K) and remove unit (L), see
Fig. [6].
6. The valve body is equipped with service stop valves (I),
close the hot and cold water supplies by turning the screws
vertically. Otherwise shut off the supply at the nearest
source.
7. Remove the four corner screws (O) and remove the valve
cover (P) as assembled unit with the O-ring (Q).
8. Pull the cartridge-holder (R) straight out of the valve body.
Rotate the cartridge-holder (R) 180°. Place it into the valve
20 psi
body. Note position of hot "H" and cold "C" markings on the
20 – 72.5 psi
cartridge: "H" hot will now be on the right and "C" cold on
the left. Make sure when sliding cartridge-holder (R) into
the body that the cartridge holder fits into the positioning
125 psi
grooves (S) of the body, see Fig. [7].
500 psi
9. When correctly engaged the cartridge holder will not
33 L/min or 9 gpm
rotate.
10. Take care not to damage inlet O-ring (W).
180 °F
11. If the the O-ring (Q) is not on the valve cover (P) re-install
and make sure the surface of the valve cover and the O-
ring (Q) are both clean, see Fig. [6].
12. Seat the valve cover (P) with assembled cartridge in the
cold - RH
cartridge-holder (R). Do not pinch the O-ring (Q). The
hot - LH
assembly should fit together with a minimum of pressing
force. Install the cover screws (O). Tighten lightly in a
diagonal pattern, then tighten firmly.
13. Open service stops valves (I) by turning the screws
horizontally. Otherwise open the supply at the nearest
source.
14. Re-install all parts and be sure that the adapter (C) will be
on the fitting template, see Fig. [1].
Plaster and tile the wall
Do not remove the fitting template before final installation.
