3 way valves
Using of 2 or 3 way valves is compulsory when the unit is used for cooling to avoid condensate in the external structure (bearing structure and cabinet). As alternative
install a regulating system to stop coil water entering when the fan is off.
Maximal fan static pressure
When the unit is connected with ducts fan air flow is reduced due to the ducting pressure drops.
With very high pressure drops fancoil air flow becomes too low and electric motor which is connected to the fan can be damaged. For this reason we recomand static
pressures lower than the maximal limit static pressures indicated in the schedule.
NOTE: when the fancoil is operating with the maximal operating indicated static pressure value, air flow is half in comparison with the unit without ducts at the same
working speed.
Definitively the static pressure limit value corresponds to the back pressure ables to halve fancoil air flow (as a consequence the fancoil unit performances like heating
& cooling capacity, will be reduced of about 50%).
