When starting the system, make sure that the lock-shield
on the hydraulic unit is open. If there is a power black-out and the thermal valve is already running, use its cap to
press the valve shutter and open it.
Filling system
Coil vent
Air exhaust when filling the system
- Open all the system’s shut-off devices (whether
manual or automatic);
- Start filling the system by slowly opening the water
tap;
- With the aid of a screwdriver, work the vent on the
uppermost coil connection (see figure below);
- When water begins to leak out of the breather valves,
close them and continue to fill the system (as per the
rated specifications).
Check the tightness of the gaskets.
We recommend that you repeat this operation whenever
the device has been running for a few hours and that you
regularly check the system’s pressure.
Wiring
- Access the electrical parts as described in para. "Front
opening for installing the device and connections" on
pag. 31.
- An on/off switch with delayed fuses or an automatic
circuit breaker (2A) must be installed to supply power
to the system.
- Because the wiring features a suppression filter, as
required by the applicable laws and standards, which
naturally induces micro-dispersion on the ground, it is
best to install selective circuit breakers upstream of
the system.
- For safety reasons, the on/off switch referred to above
should be installed near the device or at any rate in
open view.
- The power cables must be equipped with copper
conductors having the following unitary sections (the
values indicated refer to a maximum line length of
15 mm). The cables must be appropriate for the type
of installation, in accordance with the applicable CEI
standards.
