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 : 70°C
Recommended hot water temperature : 60°C (energy-saving)
Temperature adjustement zone (approximate) : 20°C to 50°C
Safety button set at : 38°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 the tool supplied.
• Lock in place.
➁
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.
➀
• Connect faucet to water supply.
UTILISATION
- Set the temperature by slowly turning the temperature selector (right handle).
- For safety reasons, there is a stop that limits temperature to 38°C. To get a higher
temperature, push the button and continue turning the temperature selector.
The bath/shower mixers feature a flow diverter that automatically returns to the bath position.
When the mixer runs in the bath position, pull down the diverter ring 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. (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;
Fig. 1
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 (fig. 2).
- 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.

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 3,4 and 5.
The cartridge is a sensitive component, so handle with case.

REMONTAGE
- 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).
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 mark (fig. 6 and 7).
- Install the temperature handle (without turning the spindle) lining the number 38 with the mark (fig.9).
- Fit the temperature handle.

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.
