Solution
Allow sufficient time for the appliance to
dehumidify the room to the required level.
On first use, the appliance must operate
continuously for at least 24 hours, in order
to obtain the desired level of air humidity.
In order to achieve better air dehumidification
results, set a lower humidity level in
percent (%) or select a continuous mode
that provides maximum dehumidification
performance.
Remove the curtains, furniture or other items
obstructing the air inlet or outlet grilles.
Close all doors, windows and other
openings in the room.
Clean the air filter.
Operating temperature range: 5-35°C.
Place the dehumidifier away from the
appliances the blow humid air in.
Disconnect the condensate drain tube and
insert the plug into the drain opening.
Check the drain tube connection to the
drain opening for leaks.
