WARNING
To prevent water from spilling out of the humidification tray, on first starting set
the pressure reducer to minimum value and close the water cock inside the unit.
Checking operation
When starting the unit check that the Automatic Humidification System operates correctly.
Act as follows:
a) set the pressure reducer to minimum value and close the water cock inside the unit (see above);
b) when the unit is operating, increase the humidity set value so that humidification is required (note: the
set cold room temperature must have already been reached);
c) check operation of the humidification heater;
d) when the tray is empty and the heater operating, check that water solenoid valve lets water flow out;
e) open water cock slowly, letting water flow out sufficiently but slowly;
f) when the humidification thermostat bulb is immersed, check that the solenoid valve is de-energised.
Periodically check that no excessive scales form on humidification heater and on thermostat bulb which
could result in:
a) burnt humidification heater,
b) malfunctioning of humidification thermostat with consequent uncontrolled water level in tray.
In case of scales clean the parts involved using special scale-removing products available on the market.
WARNING
Cleaning operations must be carried out only when the unit is off.
