WARNING: check that the power supply is disconnected
before performing operations on the unit.
WARNING: the electrical connections, the installation of the
fan coils and relevant accessories should be performed by a
technician who has the necessary technical and professional
expertise to install, modify, extend and maintain systems, and
who is able to check the systems for the purposes of safety
and correct operation.
In the specific case of electrical connections, the following
checks are required:
- Measurement of the electrical system insulation strength
- Continuity test of the protection wires.
The essential instructions for the proper installation of the
equipment are shown here.
The completion of all the operations in accordance with the
specific requirements is however left to the experience of the
installation engineer.
The command device is made up of an electronic control
panel, to be secured to the wall.
Avoid installing the control panel in places directly exposed
to sun rays, draughts, heat sources and fan coil flow. Install
the unit at about 150 cm from the floor, on an internal, air-
conditioned wall. Secure the panel to the wall using expansion
plugs.
Connect the wires to the control board as indicated in the
wiring diagrams.
