2. INSTALLATION AND TESTING
2.1 Installing the unit
The mixing unit can be installed directly on the wall connected to distribu-
tion manifold or fixed by means of suitable plugs and screws (depending
on the kind of wall) to be applied in correspondence of the holes (ref.
fig.A) to be drilled on bodies constituting the unit.
The unit can also be installed in a metal cabinet if it is connected to the
distribution manifolds, in this case provide a minimum depth of 120 mm.
2.2 Installation of thermostatic head with immer-
sion probe for fixed regulation immersion
probe for thermostatic regulation
To make it easier to assemble, set the maximum value on the thermostatic
head. Bear in mind you need to set it back to the temperature envisioned
in the project for the floor-mounted system.
Then insert the probe in the well (ref. Fig. A).
2.3 Limitation of the maximum temperature
1. Remove the red latch (rif. fig. B).
2. Set the desired maximum temperature.
3. Locate the black dot printed (rif. fig. B) between the temperatures
70 and 20 ° C.
4. Insert the latch (rif. fig. C) in the first slot which precedes the black
dot.
After successful operation, the knob can not be positioned on higher
temperatures than desired.
2.4 Testing and filling
– Carry out the hydraulic test on the unit, close the valves and the
lockshields on the distribution manifold.
– At the end of the test, reduce the pressure inside manifolds using
the drain valves.
– Now fill each circuit individually by opening the valve and lockshield
of the single way until all the air comes out.
– For a correct filling connect the water supply to the drain valve in the
flow manifold on the top and a tube to the drainvalve in the return
collector. Inside the mixing unit there is a check valve that prevents
backflow circulation inside the unit, thereby making it easier to expel
the air inside the circuits (fig. D and E).
