Operating Principle - Rowenta DH4120 User Manual

EN
Excessive atmospheric humidity makes a house uncomfortable and can have adverse conse-
quences.
Your dehumidifier allows you to remove damp air from your home by collecting the excess water
vapour suspended in the air. It protects your living environment from the damaging effects of ex-
cessive humidity.

Thanks to its DRY function, your dehumidifier can also help you dry your washing even faster.
DAMPNESS IS EXPRESSED AS RELATIVE HUMIDITY (HR).
Relative humidity is a percentage indicating the quantity of water vapour in the air as a proportion
of the maximum amount of water vapour that the air is able to contain at that temperature.
Relative humidity is measured with a hygrometer:
• RH <50%: the air in the room is too dry.
• RH between 50 and 60%: this is considered healthy.
• RH >60%: the air is too humid.

OPERATING PRINCIPLE

– The air is drawn in by a fan system and then passes through a refrigerant evaporator where it is
cooled and the excess humidity is collected. The air leaving the refrigerant evaporator is dry and
cold.
– It then passes through the refrigerant condenser which warms it before it is dispersed through
the room.
– The condensed water is collected in the tank or removed through a hose for continuous drainage.
LOCATION
First place the dehumidifier in the room requiring priority treatment.
To maintain a good level of humidity throughout the home, the dehumidifier should then be ins-
talled in a central position.
The air must be allowed to circulate freely; ensure that the appliance is not installed behind cur-
tains or near any other obstruction and leave a minimum free space of 10 cm (4 in) on all sides of
the appliance.
