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
structure of the device while the fan is
functioning, the average temperature of
the water must not be lower than the
limits shown in the table below, that
depend on the thermo-hygrometric con-
ditions of the air in the room.
The limits mentioned above refer to
operation while the fan is set
to its minimum speed level.
In the event of prolonged fan inactivity
and with cold water passing through the
coil, condensate may form on the exter-
nal case of the unit. As a result, we rec-
ommend including the three-way valve
accessory.
OPERATING LIMITS
The fan coil is a room air treatment terminal unit for mainly summer operation.
Install the unit on the suspended ceiling.
AVAILABLE VERSIONS AND SIZES
VEC fan coils are available in:
4 sizes with a 3-row coil compulsory accessory
VEC 20 VEC 20 GL
VEC 30 VEC 30 GL
VEC 40 VEC 40 GL
VEC 50 VEC 40 GL
DESCRIPTION OF THE UNIT
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.
The use of water at high temperatures
could cause squeaking due to the
different thermal expansions of the
elements (plastic and metal), this does
not however cause damage to the unit if
the maximum operating temperature is
not exceeded.
Maximum water input temperature ........................... 50°C
