Electric Controls; Control Panel - Daikin LMSW Series Installation & Operation Manual

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.
