OPERATING CONDITIONS FOR THE THERMOSTATIC MIXER
Indicated pressure is measured by flow (dynamic pressure)
Minimum/maximum water supply pressure : 0,5 bar/5bars
If water supply pressure exceeds 5 bars : Install a pressure reducer
Recommended water supply pressure : 3 bars on hot and cold water
Pressure difference : 2 bars maximum
Minimum hot water supply temperature : 50°C
Maximum hot water supply temperature : 80°C
Recommended hot water temperature : 60°C (energy-saving)
Temperature adjustement zone (approximate) : 20°C to 50°C
Safety button set at : 40°C
Maximum hot water temperature from mixer : maxi 50°C
INSTALLATION
- Drain pipes thoroughly before installing. After installing mixer, remove aerator. Turn on water supply. Turn flow
control handle to full flow. Turn temperature selector to hot, for the hottest water temperature, then to cold, for the
coldest water temperature, to remove all deposits. Reinstall aerator.
- The hot water connection must be done on the left (near the flow setting handle).
WALL INSTALLATION
• Seal fittings.
• Install eccentric fittings horizontally, 150 mm apart. They should extend
40 to 45 mm from finished wall.
• Screw on escutcheons, position washers and then tighten nuts with an
open-end wrench # 30.
• Lock in place.
OPERATION
Setting position plant
- Set the temperature by slowly turning the temperature
selector (right handle).
- For safety reasons, there is a stop that limits temperature
to 40°C. To get a higher temperature, push the button and
Stop
continue turning the temperature selector.
- Adjustable water flow is set by turning the left handle.
- There is also a water-saving stop. To obtain a higher flow
rate, push the button and continue turning handle.
If the pre-set water saving stop is not appropriate (about
70% of the outlet shower bush-flow), it can be modified as
follows:
- Close mixer, note the position of flow setting handle and
dismantle it without turning it.
- Pull out the stopper, and shift one or several notches,
Increase the flow
according to drawing.
- Install the flow setting handle in the original position.
The bath/shower mixers feature a flow diverter that
Decrease the flow
automatically returns to the bath position. When the mixer
runs in the bath position, push the diverter button to go to
the shower position; after flow is shut and reopen, water will
run again in the bath position.

CARE AND MAINTENANCE

Finish: This mixer has a finish which requires special care. To maintain its shine
and luster, clean regularly with a non-abrasive sponge and soap, rinse thoroughly and
dry with a soft cloth. Do not use harsh products containing methyl alcohol, acids, solvents
or abrasives that can damage the finish.
Thermostatic cartridge : Very hard or highly charged water can obstruct the
filters protecting the thermostatic cartridge and reduce the flow of water. Clean the filters
by soaking the thermostatic cartridge in which they are inserted in warm vinegar after
following the instructions in the paragraph on removing the cartridge.
Filters and non-return valves : The filters, protecting the mixer device can get
clogged and reduce water flow. When this happens and remove the mixer clean the filters
by soaking them in warm vinegar.
Impureties may prevent the non-return valve in the inlet connection from closing. This
causes an improper mix of hot and cold water; to correct this, clean the valves as follows:
- Using a 12mm socket wrench, unscrew the pin containing the filter and non-
return valve by turning the wrench clockwise, push it with the wrench, then extract it.
- When replacing the check non-return valve, make sure it opens in the same
direction as the water flow.
This thermostatic mixer operates correctly
with a storage water heater but can also be
used with an instantaneous gas heater with
a power rating of 18 Kw or 250 mth/min.

TESTING AND SETTING
The factory setting is appropriate for most home systems. However, it is possible that the temperature
of the water run by the mixer is not exactly the one noted on the selector. In this case, the installer
can adjust the setting.
Caution: Before testing the mixer, make sure that hot water and cold water come out with a right flow;
to do this, turn the temperature selector all the way to the ''hot'' stop then to the ''cold'' stop.
Testing: With the selector in position 37, the temperature of the water coming out of the mixer should
be within a range of 36° and 38°C (measure with a bath thermometer). If this is not the case, proceed
with the setting as follows:
Setting: With the mixer on ''cold'' and normal water flow, slowly turn the temperature selector (always
in the same direction) until water at 37°C is obtained. If the temperature goes over 38°C, go back to
the ''cold'' setting and set again.
- When the temperature is stabilized, pull out the temperature handle slowly without turning it (use a
cruciform screwdriver).
- Install the temperature handle, (without turning the spindle) lining up the number 37 with the mark.
Tighten the assembly with the screw. (See fig. 1)
CHANGING THE THERMOSTATIC CARTRIDGE
REMOVAL
Close the water feed upstream of the mixer and open the water flow handle, then proceed to remove the cartridge as shown in figures 2,3 and 4.
The cartridge is a sensitive component, so handle with case.

ASSEMBLY
- Install the ''stop assembly'' home on the cartridge, adjusting the stop pin in the notch (fig. 5).
- Install the assembly cartridge + stop in the body, adjusting the stop pin in the notch (fig. 6).
- Screw the nut home, and tighten slightly.
Note : The cartridge can be installed without any grease, but using only silicon grease facilitate operation would and not damage the o-rings.
- Check that the black line is correctly in line with the slot (fig. 6).
- Install the temperature handle (without turning the spindle) lining the number 37 with the mark (fig.7).
- Tighten the handle with the screw.

PREVENTION AGAINST FREEZING
After purging the plumbing system, evacuate water in the mixer as follows :
1 - SHOWER thermostatic valve mixer
- Remove the shower hose from the thermostatic valve mixer.
- Turn the water flow handle to the ''open'' position and slowly turn the temperature selector. Let water run out.
2 - BATH/SHOWER thermostatic valve mixer
- Remove the shower hose and the aerator located at the end of the thermostatic valve mixer spout.
- Turn the water flow handle to the ''open'' position and slowly turn the temperature selector and the flow diverter button. Let water run out.
NOTE : We recommend that you install a stop-valve on the hot water pipe and the cold water pipe upstream of your thermostatic valve mixer, for easier
mixer maintenance.
