• Sizing the pipes correctly will avoid problems of pressure loss and unwanted noise.
• Protect the installation with filters, water hammer absorbers and pressure reducers to reduce the
frequency of maintenance. (Recommended pressure: 1 - 5 bar).
• Install stopcocks close to the mixer to facilitate maintenance.
• The pipework, stopcocks, mixers and all sanitary ware must be checked regularly, and at least once a
year.
CLEANING & SERVICING
• Cleaning chrome:
Do not use abrasive, chlorine or any other acid-based cleaning products. Clean with soapy water using a
cloth or sponge.
• Frost protection:
Drain the pipes and operate the mixer several times to drain any remaining water.
If the installation
remains unused for a period of time we recommend removing the cartridge mechanism storing it in
the shade at room temperature.
MAINTENANCE
To remove the mechanism (fig.
)
:
• Remove the central cap
using a pair of circlip pliers.
• Unscrew the blocking screw with a screwdriver and remove the push-button control
by hand.
• Partly unscrew the 3 cartridge-securing screws
for 4 turns using a screwdriver. The water pressure will
raise the mechanism.
• Shut-off the hot and cold water supply using the stopcocks.
• Unscrew the 3 cartridge-securing screws
completely and remove the locking cap
+
by hand.
• Remove the mechanism by hand.
Impurities in the pipework may cause the valve to malfunction:
Inaccurate or continuous flow
(fig.
):
• Clean the inside of the timing chamber using a dry cloth and the calibrated groove with a non-
metallic pointer.
• Check the condition of the piston lip seal JN29 , and the O ring JR2 .
Constant dripping or a trickle of water
(fig.
):
• Check the condition of the O ring JR2 and the washer JR6 bis .
Problems in achieving the correct mixed water temperature:
• Balance the water pressure HW/CW (∆P < 1 bar)
• Check that there are no impurities on the non-return valves
(figs.
,
).
• The non-return valves should be checked at least once a year.
NB: The joints between the stainless steel wall plate and the wall, and between the wall plate and the
body of the mixer, should be checked at least once a year to ensure that they are watertight. Check
more frequently if required, and replace as necessary.
