To prevent the grille from being accidentally removed or left loosened by the quick-release pads preventing the fan coil from functioning
properly (in this case, the ventilation stops and the grid safety alarm appears) 2 screws are provided for fastening the grid.
The screws are TC 4,2x9,5 mm type.
So it it takes just fix the screws in dedicated holes located on grill’s fixing bars.

The choice and sizing of the hydraulic lines must be made by an expert who must operate according to the rules of good technique
and the laws in force, taking into account that undersized pipes cause a malfunction.
To make the connections:
-
position the hydraulic lines
-
tighten the connections using the “spanner and counter spanner” method
-
check for any leaks of liquid
-
coat the connections with insulating material.
The hydraulic lines and joints must be thermally insulated.
Avoid partially insulating the pipes.
Do not over-tighten to avoid damaging the insulation.
Use hemp and green paste to seal the threaded connections; the use of Teflon is advised when there is anti-freeze in the hydraulic
circuit.
