3-WAY VALVE WITH DIVERTER
VALVE THERMOELECTRIC
HEAD KIT
It consists of a 3-way diverter valve
with a thermoelectric head and
a retainer fitted with micrometric
adjustment that can balance the
pressure drops of the system
(fig. 9).
Inside the kit there is the insulation
material to be fitted on the valve
and on the retainer.

CONNECTIONS
The designer is responsible for
choosing and sizing the hydraulic
lines, and must proceed according
to technical standards and current
legislation.
To make the connections:
- position the hydraulic lines (fig.
9 ref. A)
- tighten the connections using
the “dual key” method (fig. 9 ref.
B)
- check for leaks
- cover the connections with
insulating material (fig. 9 ref. C).
The hydraulic lines and joints must
be thermally insulated.
Avoid partial pipe insulation.
Avoid tightening too much so as
not to damage the insulation.
For the threaded connections to
be water tight use hemp and green
paste; Teflon tape is recommend-
ed in the presence of antifreeze
liquid in the hydraulic circuit.

ETM, ETI versions
- floor-mounted connections
version (fig. 20)
- wall-mounted connection
version (fig. 21) (with spacer
stub 3/4”)
- Apply the insulating material
provided.
Once the hydraulic com-
ponents have been as-
sembled, connect the
thermoelectric head con-
nectors to the wiring connectors
found on the machine.
FITTING THE THERMOSTATIC HEAD
Screw the head tightly to the valve body.
Do not use mechanical tools to install the head, but only your
hands!
The thermostatic head is supplied with a red tab that keeps it open so
as to facilitate installation, filling and bleeding the system, even in the
event of a power failure.
Remove the tab when starting up the system
so as to prevent the valve from remaining open at all times
