2. GENERAL ADVICE
Before putting your dehumidifier into operation for the first time, the instructions manual should be studied carefully.
After receiving the unit, you should check your dehumidifier for any transport damage. In case of damage, you should
inform the sender immediately.
Transport damages should be stated after unpacking the equipment. The respective seller or specialised reseller
should be contacted immediately.
Keep the packaging of the dehumidifier in a safe place in order to be able to despatch the dehumidifier safely if it
requires a service. In order to save space, you can simply cut through the adhesive tape using a knife and unfold the
cardboard box.
3. DEHUMIDIFIER PRINCIPLES
This dehumidifier is designed to reduce humidity from the air in a building or part of a building. The purpose is to
prevent humidity damage, and to dry out wet materials such as carpet, floors, walls, furniture, contents, timber, and
structural materials.
This dehumidifier can prevent the formation of condensation, reduce air humidity and keep constant a desired relative
humidity value. The time necessary for the dehumidifier to dry a room and reach the desired relative humidity depends
on the environmental conditions prevailing within the room. For example the number of air changes with outside, any
sources of moisture and the room temperature can all either speed up or slow down the dehumidification process.
The dehumidifier functions according to the condensation principle with heat recovery. The fan takes the humid air
from the room in and across a filter and then through an evaporator. Here the air is cooled below dew point so that the
water vapour of the air forms a condensate on the coils which flows into the water collecting tank. The cooled and
dried air is heated again by a condenser. By recycling the room air through the dehumidifier over and over again the
moisture content and relative humidity of the air is reduced.
4. INSTALLATION AND TRANSPORTATION
For installation and transportation, the following instructions must be considered:
The air inlet and the air outlet must not be covered whilst the dehumidifier is in operation.
Before any moving the dehumidifier it must be switched off by its ON-OFF switch. The mains plug is to be
removed from the socket and the water tank should be emptied.
For transportation the dehumidifier should be secured on a level base only and must be prevented from rolling
around.
The dehumidifier must always be transported vertically.
This dehumidifier must be used exclusively for air dry.
If the dehumidifier has been in a horizontal position for any time over a few minutes, you must let it stand in
the upright position for at least 30 minutes before operating. This allows the oil to drain back into the
compressor.

6 [EN]
5. OPERATING INSTRUCTIONS
ATTENTION
- Operate the dehumidifier only in the upright position.
- Plug in to a standard outlet with the correct voltage and amperage for the unit.
- Allow five minutes before restarting after the unit shuts off for any reason. This will avoid damaging
the compressor.
- Check dehumidifier daily for correct operation.
- Protect floor surfaces from water.
Please proceed as follows to start using this dehumidifier:
After transported, the dehumidifier should be allowed to stand for 30 minutes. This procedure is recommended
to extend the compressor’s operating lifetime.
Put the plug into the socket.
Check whether the electric supply source voltage is 115V, or 230V and switch to the correct voltage on the
dehumidifier. The voltage control panel (voltage switch and circuit breaker) is covered by a plate located on
the top of the side panel.
Check that the water tank is in position.
If working with a remote hygrostat set the required humidity value on it (see point 9).
Switch on the I/0-switch and check if time counter is running. Both I/0 switch and the time counter are
located in the upper right side of the dehumidifier, along with the leds (see point 6). The control panel must
be illuminated after switching on the I/0 switch. Check for the proper operation of both the fan and
compressor before leaving the unit unattended.
NOTES:
If the dehumidifier is supplied with 230V and the dehumidifier is switched to work with 115V (a), the compressor
won’t start due to lack of energy. If the dehumidifier is supplied with 115V and the dehumidifier is switched to
work with 230V,(b) it will be shut down by the circuit breaker. Proceed as follows to work properly:
- Switch off the dehumidifier in the main switch and unplug the dehumidifier from the supply source
- Switch the dehumidifier to work with 230V (a) or 115V (b)
- Switch on the circuit breaker (b)
- Plug in the dehumidifier to the supply source and turn on the dehumidifier in the main switch

7. CONDENSATE OUTLET
This dehumidifier is equipped with water collecting tank and with fittings for 9/16” (14mm) hose. If working with a
water collecting tank, the appliance will automatically switch off when full and the red light at the control panel (see
page 6) will light up.
To use the hose for the draining the condensate, you should proceed as follows:
Remove the plug from the bottom of the water tank;
Fasten the 9/16” (14mm) fitting in the bottom of the water tank;
Attach the hose supplied with the dehumidifier to the 9/16” (14mm) fitting;
The end of the hose must always be at a lower plane than the top of the water tank and headed to a larger
vessel or directly to a drain. The hose must be going downhill as it uses gravity to drain.
8. AUTOMATIC DEFROSTING SYSTEM
During normal dehumidifying operation, ice may form on the evaporator. This dehumidifier is equipped with an
automatic hot-gas defrosting system and if ice is detected by the temperature sensor, it will defrost automatically
according to the following principle:
A temperature sensor measures the condition existing in the critical area of the evaporator;
It transmits an electrical signal to the main electronic board. It has been designed to avoid frequent defrost
cycles and consequent loss of efficiency;
The relay switches off the fan and simultaneously opens the solenoid valve;
Hot gas is guided into the evaporator until the latter is completely free of ice;
Subsequently, the dehumidifier will operate again in its normal mode when the temperature sensor measures
+7°C;
The time between defrost cycles is 20min after;
9. CONDENSATES PUMP WORKING MODE (OPTION)
Switch off the dehumidifier and disconnect the mains plug from the socket;
Remove the water bucket from the dehumidifier and empty it;
Fit in an 8mm hose (inner diameter) with the desired length onto the water outlet of the submersible pump and
make it pass through the hole in the left side panel and then install the pump inside the bucket;
Plug in the pump to the pump socket located beneath the water pan in the right and return the bucket to its
room;
Extend the hose to an existing drain point or sewer always below 4m height from the pump level (elevation
depends always on the pump used);
Plug in the dehumidifier and switch it on;
Test if the pump is working and is draining out water by adding water to the bucket until you check that the
water is being pumped out from the bucket;
