- CAUTION: make sure that electrical power to the unit is turned off before making any electrical connection.
- CAUTION: wiring connections, unit installation and all accessories have to be made only by specialised
installers.
- Please do not forget that warranty cannot be applied in case of electric, mechanical and other general modi-
fications.
- Compliance with the safety norms/laws applied in the country where the unit is installed.
- Make sure that the technical data concerning the network meet the data indicated on the identification unit label.
- Unit and accessories (230V electrical heater, remote controls, etc.): power supply: Check that the line is single-phase 230V
/ 1Ph / 50Hz and that the voltage remains within the limits 230 Vac ± 10%.
- The work of the unit with voltages that are not within the above mentioned limits makes the guarantee unvalid.
- Make sure that the electrical plant is able to supply in addition to the working current required by the unit also the current
required to supply the domestic units already in use.
CHECK THE EARTHING
- The electrical safety of the unit is attained only when the unit itself is correctly connected and efficiently earthed according
to the existing safety standards.
- When connecting, ensure that the earth wire is longer than the live wires, so that it will be the last wire to break if the
supply cable is stretched, thus ensuring a good earth continuity.
CONNECTION CABLES SPECIFICATIONS:
- Carry out all unit connections using cables of adeguate dimensions for the power used in accordance with the local laws in
force. Their dimensions must be of such dimensions to cause a phase voltage drop of less 3% of the nominal voltage.
- Use H05V-K or N07V-K insulated cables with 300/500 V, piped or ducted.
- All cables have to be piped or ducted until they are not placed inside the terminal board of the unit.
IT
- The cables coming out of the pipe/duct have not to be subjected to stretch or twist. They must be protected from weathering.
Stranded cables shall only be used in connection with terminating sleeves. Make sure that all individual cables are correctly
inserted in the sleeve.

ELECTRICAL CONNECTIONS:

MAKE THE ELECTRICAL CONNECTION IN COMPLIANCE WITH THE INSTRUCTIONS OF THE SYSTEM DESIGNER
AND IN COMPLIANCE WITH THE ELECTRICAL DIAGRAM ENCLOSED WITH THE UNIT AND ACCESSORIES
- The use of adapters, multi-plugs and/or extension cords is not permitted for unit main power supply.
- It is the installer's responsibility to install the unit as close as possible to the general power switch !!
- To prevent short circuits, the unit should be connected to the electric supply line by means of an omnipolar magnetothermic
switch with a minimum contact opening of 3 mm (see electrical absorbing schedule to chose the right switch). An omnipolar
switch is a ''Double pole isolating switch'', i.e. a switch capable of disconnecting both on phase and neutral. This means
that when the switch is opened, both contacts are disconnected. The omnipolar switch or the plug (connection by means of
cable and plug) must be mounted in places easy to reach.
ELECTRICAL ABSORPTION: Make reference to the electrical absorption written on the unit label.
EACH CONTROL PANEL CAN CONTROL ONE SINGLE UNIT ONLY.
NOTE: To control more than 1 unit (or 1 unit with 2 motors) it is recommended to keep the electrical power supply
of the different motors SEPARATE AND INDEPENDENT FROM EACH OTHER. To do so, it is recommended to
install 3 relays (one each speed) by independent contacts (one contact each motor to be controlled) or install
the INTERFACE CHART (accessory): this way should any inconvenience happen to any of the fan motors, it
would not involve nor interfere with the others !!
- For installation of control panel choose an area where the max and min. room temperature limit is respected 0÷45°C ; < 85% U.R.
Do not install the control panel on metallic walls, if the metallic wall is not permanently earthed.
