The kit is composed of a valve, the relative actuator and
UK
one gasket.
The valve is the open or closed type with 1/2" connections,
having single-phase 230 V 50/60 Hz electrical requirements.
The valve can be controlled from command panels (accessori-
es) enabled with the valve control function; before selecting,
consult the characteristics of the command panels.

INSTALLATION
WARNING: before performing any maintenance interven-
tion, make sure that the power supply has been cut off.
WARNING: the electric connections, installation of the fan
coils and their accessories must be performed only by persons
possessing the technical and professional qualifications ena-
bling them to perform installation, convert, expand and main-
tain the plants and capable of performing functionality and
safety checks on the plants.
In particular, for the electric connections, the following checks
are needed:
- Electrical system isolation resistance measurement.
- Protective conductors continuity test.
Before installing the VHL 2 kit consult the FCL fan coil installa-
tion manual; it is the installers task to prepare the water and
electrical systems, and to correctly perform the connections with
the unit.
The installation must be performed according to that illustrated
in the given diagrams, using the gaskets supplied with the kit of
the machine.
WARNING! During the installation pay attention to the direc-
tion of flow, before mounting the valve check the mounting
direction by referring to the symbol stamped on the body of the
valve.
The valve body must be installed without excessive torsion,
between 25 and 30 Nm.
Connect the electrical wires of the valve to the terminal strip of
the unit as indicated in the attached wiring diagrams.
