9. MAINTENANCE
NOTE: Before starting the maintenance activities, switch off
the device by means of the switch (a) and disconnect it from
the mains.
In order to ensure efficient operation, clean the filter as well as
the internal elements of the dehumidifier periodically. The air filter
should be blown through with compressed air or washed in warm
water with soap.
NOTE: In order to remove the filter, loosen the lock screw
which is over the filter.
In order to clean the inside of the device, unscrew and remove
the front cover of the filter. The pollution must be removed by
means of a vacuum cleaner, making sure that the ribs of the
condenser, evaporator and fan blades are not damaged in the
process.
10. TRANSPORT
NOTE: In order to move or transfer the dehumidifier, switch
off the device by means of the main switch and pull the plug
out of the mains socket.
In order to move the dehumidifier, tilt it. This enables the
transport of the device on wheels (fig. 7).
NOTE: Do not transfer the dehumidifier in a horizontal
position.
The method of transfer of the dehumidifier along the stairs or a
steep surface is presented in fig. 8.
11. NOTES REGARDING THE DISASSEMBLY
In the compressor circulation system, there is a R407C
pressurized refrigerant.
SYMPTOM
The device cannot be started
The fan and the compressor are
operable, but neither water nor ice
appears on the walls of the
evaporator
The device stopped the operation,
the indicator lamp is back-lit (e)
The device stopped the operation,
12. FAULT DETECTION AND TROUBLE-SHOOTING
POSSIBLE CAUSES
1
Lack of supply voltage
2
Improper humidistat setting
3
The water reservoir is filled up (the
indicator lamp is back-lit)
4
Too low ambient temperature (the c
control lamp is back-lit)
5
Too high ambient temperature (the
c control lamp is back-lit)
1
Too little air flow
2
Too low room temperature and/or
relative air humidity
3
Faulty operation of the refrigerating
system
1
The water reservoir is filled up
1
The air flow is blocked
13
Additionally, there is oil inside the compressor. For these
reasons, throwing the exploited device away is not allowed.
Disassemble it, and the respective elements must undergo
secondary processing or scrapping.
NOTE: The refrigerants must not be emitted into the
atmosphere. The refrigerant should be removed by qualified
persons.
The following items are necessary to remove the refrigerant:
pliers for a removal of refrigerants,
unit for forcing through the liquids,
pressure vessel.
The refrigerant should be removed in the following way:
connect the pliers and the pressure vessel to the
unit,
puncture the drain pipe of the compressor with the
pliers and leave them clamped on the pipe,
open both valves of the unit and start it, emptying
the used refrigerant from the drier,
switch off the unit and shut both valves, then shut
the pressure vessel valve,
remove the pliers from the pipe,
if the pressure vessel is filled up, deliver it to a
specialist liquid waste removal point.
In order to remove the oil from the compressor, solder it out or
cut it off from the refrigerating system and unscrew it from the
base. Then, drill a hole in the compressor housing (from the
bottom), through which the oil may be poured out.
NOTE: Deliver the used oil to the oil removal point.
The remaining elements (mainly steel, copper and aluminium
elements) may be delivered for secondary processing.

Check whether the main switch
functions properly and whether it is
in the ON position
Check the supply voltage (230 V,
1~, 50 Hz)
Set the humidistat to the humidity
level lower than the room
temperature
Empty the reservoir as specified in
the section entitled Water reservoir
Check whether the ambient
temperature is higher than 5° C
Check whether the ambient
temperature is lower than 40° C
Check whether the air inlet or air
outlet is not blocked
Check whether there is deposit on
the filter or ribbed condenser or
evaporator blocks
Check whether the temperature is
within the range of 5º- 40ºC, and
whether the relative humidity ranges
from 40 to 95%
Call the authorised service
Empty the reservoir
Remove the objects which obstruct
