BEARING STRUCTURE
it is made of galvanized sheet metal of adequate
thickness. in the back there are holes for fixing
the appliance to the wall. the fan unit is closed
at the front by a metal panel. each appliance
is equipped with condensate collection basins
both for vertical installation and for horizontal
installation.

Water temperature
In order to prevent air stratification in the
room, and therefore to achieve improved
mixing, it is obligatory not to supply the fan
coil with water at a temperature over 50°C.
Minimum average water temperature
If the fan coil is working in cold continuous
mode inside an environment where the
relative humidity is high, condensate
might form on the air delivery. This
condensate might be deposited on any
objects underneath and on the floor.
To avoid condensate on the external struc-
ture of the device while the fan is func-
tioning, the average temperature of the

each appliance is equipped with condensate

HYDRAULIC CONNECTIONS
the connections, positioned in the left side, are
female-mounted. it is possible to rotate the

The use of water at high temperatures

water must not be lower than the limits
shown in the table below, that depend on
the thermo-hygrometric conditions of the

The limits mentioned above refer to opera-

FITTINGS FOR SUPPLY AND SUCTION
the vec_ii_p fan coils are compatible with all the
accessories already available for the fan coils
of the vec_i_p series
CONTROL PANEL
use a control panel with thermostat and fan
speed control with 0-10v outputs.
for installation consult the accessory manual.
