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
40 à 45 mm
• 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 # 41 with the nut protector supplied.
• Lock in place
DECK-MOUNT INSTALLATION
• Fix deck-mount connections to faucet.
• Insert fixing screws with an allen wrench.
• Position faucet on bathtub, screw and tighten nuts on connections.
• Tighten fixing screws.
• Connect faucet to water supply.
OPERATION
Stop
- Set the temperature by slowly turning the temperature selector
(right handle).
Setting position plant
- For safety reasons, there is a stop that limits temperature to
40°C. To get a higher temperature, push the button and 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
Increase the flow 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, according
to drawing.
- Install the flow setting handle in the original position.
The bath/shower mixers feature a flow diverter that automatically
returns to the bath position. When the mixer runs in the bath
Decrease the flow
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.
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.

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. (See
fig.1 and 2)
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,
Fig. 1 push it with the wrench, then extract it (fig. 2).
- When replacing the check non-return valve, make sure
it opens in the same direction as the water flow.
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. 3)
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 4,5 and 6.
The cartridge is a sensitive component, so handle with case.

Fig. 4
ASSEMBLY
- Install the ''stop assembly'' home on the cartridge, adjusting the stop
pin in the notch (fig. 7).
- Install the assembly cartridge + stop in the body, adjusting the stop
pin in the notch (fig. 8).
- 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. 8).
- Install the temperature handle (without turning the spindle) lining the
number 37 with the mark (fig.9).
- 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.
