c. For SL models installed in vertical position, work using a screwdriver on the highest breather of the battery
28) (fig.18)
For SLR models with radiant panel, work using a screwdriver both on the side breather of the valve and
on the manual breather of the radiant panel (29) (fig.18-19).
d. When water starts coming out from the breather valves of the appliance, close them and keep loading
until the nominal values envisaged for the system.
Check for water tightness of the seals.
It is advised to repeat this operation after that the appliance has worked for a few hours and to
periodically check the system pressure.

2.11 - ELECTRICAL CONNECTION

The fan coil is equipped with a power cable with Schuko plug.
In the case of use of a power socket next to the appliance, it is only necessary to insert the plug.
Alternatively, it is possible to proceed with the connection by means of an in-wall cable removing the supplied
power cord from the terminal block.
Remount the front panel before powering the unit.

2.11.a - Configuration
The printed circuit board must be configured depending on the type of installation and based on particular
operating preferences of the machine.
The three selectors J1, J2 and J3 indicated in fig. 20a-20b must be set as follows:
J1. ON: in night mode, heating works in natural convection and irradiation mode only, without ventila-
tion; In all the other cases of heating, ventilation switches off approximately 1°C before reaching
the desired temperature and continues in irradiation and natural convection only up to the desired
temperature.
J1. OFF: for appliances without radiant panel: heating occurs always through forced convection, with
activation active also in night mode (at reduced speed).
J2. ON: in cooling mode, the fan remains powered even upon reach the desired ambient temperature.
J2. OFF: in cooling mode, the fan id deactivated upon reaching the set temperature.
J3. ON: for appliances to be installed in 2-pipes systems: the board is set for management of a single
water valve for summer (cooling) and winter (heating) operation.
J3. OFF: for appliances to be installed in 4-pipes systems: the board is set for management of two water
valves, one for summer (cooling) operation and one for winter (heating) operation.
