Controls
Tank control system
This dehumidifier is fitted with a special device to ensure correct
operation.
A red indicator light on the control panel comes on to warn the
user when:
1. the tank is full
empty the tank
2. the tank is missing replace the tank
3. the tank is in the wrong position position the tank correctly
4. in continuous drain: the hose is obstructed or placed too high
above the drain spout remove the obstruction.
Once the cause has been eliminated, the light goes out and the
appliance resumes operation.
Dehumidification light
This switches on when the machine is dehumidifying.The light
remains on only when the appliance is effectively dehumidifying; if
the humidity in the room is already low enough, the light will be
off.
Dehumidification standby/low temperature
operation light
The light comes on in the following two cases:
1) To signal a delay of around 3 minutes in the start-up of the
appliance.This is due to a safety device which protects the com-
pressor.
2) To signal low temperature operation.When the room tempera-
ture is too low, the electronic low temperature operation
device is activated. This device allows the appliance to operate
by alternating dehumidification cycles and fan only cycles.
This is to avoid the formation of ice. For frequent use in cold
environments, it is recommended to heat the room at the same
time.This allows the dehumidifier to operate in conditions that
ensure better performance and faster dehumidification.
Heating light
This switches on when the machine is heating.The light remains on
only when the appliance is effectively heating; if the temperature in
the room is already high enough, the light will be off.
