22. PROBLEMS AND SOLUTIONS
PROBLEM
POSSIBLE CAUSE
WHAT TO DO
The dehumidifier does not start
The dehumidifier is not correctly connected to the
power supply
Ensure that the dehumidifier plug is correctly inserted in the
socket
The dehumidifier has reached the desired humidity
level or the condensate collection bucket is full
The dehumidifier switches off automatically when these two
conditions occur. Set a lower humidity level or empty the
condensate collection bucket and re-insert it correctly
The condensate collection bucket is not in the cor
-
rect position
Position the condensate collection bucket correctly
The float is not in the correct position
Open the condensate collection bucket as described in the
Installation
paragraph and place the float in the correct
position
Interruption and then the electrical power is reap

plied
When electrical power is reapplied it is normal for the unit
starts to dehumidify correctly after 3 minutes. The protective
system ensures that there is a 3 minute time delay before
starting the compressor to avoid overloads
The dehumidifier does not
dehumidify the air as it should
Not enough time has passed to ensure the removal
of humidity
On first starting allow to operate for at least 24 hours to
reach the desired humidity
The air flow outlet is blocked
Ensure that there are no curtains, furniture or other objects
blocking the intake or outlet of the dehumidifier. See the
section on
Minimum clearance space
The filter is dirty
See the section on
Cleaning and maintenance
The humidity level set may not be sufficiently low
To have drier air press the "-" button and set a lower humid
-
ity percentage or set the operating mode to CONTINUOUS for
maximum dehumidification
Doors and windows are not closed
Check that all doors and windows are completely closed
The drier is discharging humid air into the room
Install the dehumidifier far from the drier. The drier must
discharge humid air outdoors
The room temperature is too low
The capacity of the dehumidifier is better at higher ambient
temperatures. Low ambient temperatures reduce the dehu-
midifier capacity. The dehumidifier is designed to operate at
temperatures greater than 5°C
The dehumidifier works too hard
The dehumidifier area is too big
The capacity of the dehumidifier might not be sufficient
The doors and windows are open
Close all the external doors and windows
Frost forms on the evaporating coil
of the dehumidifier
The ambient temperature is less than 5°C
This is normal. See the paragraph
Automatic defrost
The controls cannot be set
When the compressor switches off the fan continu
-
ous to work for around 3 minutes
This is normal. Wait for around 3 minutes and set the desired
fan speed
Water on the floor
The rubber tube for direct discharge may be loose
Check the rubber tube for direct discharge connection. See
the paragraph
Condensate water collection
The condensate is to be collected in the bucket
but the rubber tube for direct discharge is also
connected
If condensate is to be collected in the bucket remove the rub-
ber tube for direct discharge and insert the rubber plug in the
outlet tube. See the paragraph
Condensate water collection
The condensate is to be collected in the bucket,
the rubber tube for direct discharge is not installed
but the rubber plug is not correctly inserted in the
outlet tube
Correctly insert the rubber plug into the outlet tube
The float is not in the correct position
Open the condensate collection bucket as described in the
Installation
paragraph and place the float in the correct
position
