Installation
Before installing a kit with mixing valve, make sure the system’s operating parameters fall within the mixing valve’s working parameters, for example
in terms of supply temperature and pressure etc..
The kit with mixing valve must be installed by a qualified technician in accordance with established legislation and the instructions given in this
manual.
The system in which the kit with mixing valve is going to be installed must be flushed and cleaned to remove any dirt that may have accumulated
during installation. Failure to remove impurities may affect valve performance and void the manufacturer’s warranty.
In case of highly aggressive water, it must be treated before entering the kit with mixing valve.
It is essential that access to the valve is not obstructed, in order to allow maintenance to the valve or fittings if required. The pipes must not be used
to support the weight of the valve
During the installation, observe all current legislation regarding the maximum distance between the valve outlet and each user taps.
The kit with mixing valve can be installed in any position, whether vertical or horizontal.
The hot and cold water inlets to the valve must be connected as shown on the valve body itself.
The thermostatic mixing valves must be installed complete with shut-off valves, strainers and check valves at the hot and cold water inlets.
The shut off valves are required to enable the valve to be isolated for maintenance.
The strainers are essential to prevent impurities from entering the mixing valve.
The check valves are necessary to prevent undesired circulation and backflow.
The kit with mixing valve is supplied complete with strainers and check valves at the hot and cold water inlets.
If the kit with mixing valve is not installed according to these instructions, it may operate incorrectly and endanger the user.
Installation diagram
Installation positions
The kits can be installed in any position, vertically or horizontally.
An installation close to the boiler is recommended.
Bracketing
Anti-scald safety function
In case of hot or cold
water supply failure at
the inlet, the obturator
shuts off the water flow, thus
closing the mixed water oulet.
This performance is guaranteed
only
when
there
is a minimum temperature
difference between the inlet hot
water and the mixed water
outlet of 10°C.
