Please read the instruction manual before using the product and then save it for future reference.
We reserve the right for any error in text or images and any necessary changes made to technical data.
• Failure to abide by this warning could result in an explosion, death, injury and property damage.
• Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid
certicate from an industry-accredited assessment authority, which authorizes their competence to handle
refrigerants safely in accordance with an industry, recognized assessment specication.
• Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair
requiring the assistance of other skilled personnel shall be carried out under the supervision of the person
competent in the use of ammable refrigerants.

SAFETY INSTRUCTION
Warning on Refrigerant R290
• The machine is designed only for use with R290 (propane) gas as the designated refrigerant.
• THE REFRIGERANT LOOP IS SEALED. ONLY A QUALIFIED TECHNICIAN
SHOULD ATTEMPT TO SERVICE!
• The lack of smell does not indicate a lack of escaped gas.
• No open ames, cigarettes or other possible sources of ignition should be used in the vicinity of the machine.
• Component parts are designed for propane and non-incentive and non-sparking. Component parts shall
only be replaced with identical repair parts.
THE MACHINE MAY ONLY BE INSTALLED IN A ROOM WITH A MINIMUM FLOOR
AREA OF 4m2.
R290 is a ammable gas that is heavier than air. On this basis, if the gas leaks from the unit, the concentration will be the
highest at ground level. However, the gas can be lifted (e.g. by drought, fan, etc) to higher levels. The R290(propane) used
in this unit has no odor.
Do not use the machine in a room with an open ame, other high-level heat sources (e.g. cigarettes, candles, etc.) or electrical
discharges. Install the machine in a room which can be ventilated when necessary and where gas accumulation is not possible.
If R290 (propane) is detected in the room, or a leak is suspected, do not allow unauthorized persons to search for the source of
the leak. In such cases, evacuate all people from the room, open the windows, leave the room and notify your local re depart-
ment to advise them that a propane leak has occurred. Do not allow any person to return to the room until the commanding
ofcer of the re department or a certied service engineer decides that the risk has ceased to exist.

SAFETY REGULATIONS FOR SERVICE AND REPAIR WORK
Repairs must only be carried out by authorized service personnel and only using genuine spare parts.
1. Checks to the Area
Prior to beginning work on systems containing ammable refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
2. Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a ammable gas or vapor being pres-
ent while the work is being performed.
3. General work Area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work
in conned spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions
within the area have been made safe by control of ammable material.
4. Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is
aware of potentially ammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with
ammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5. Presence of re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts appropriate re extinguishing
equipment shall be available to hand. Have a dry powder or CO2 re extinguisher adjacent to the charging area.
6. No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or
has contained ammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of re
or explosion. All possible ignition sources, including cigarette smoking, should be kept sufciently far away from the site of
installation, repairing, removing and disposal, during which ammable refrigerant can possibly be released to the surround-
ing space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no
ammable hazards or ignition risks. “No smoking” signs shall be displayed.
7. Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any
hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely
disperse any released refrigerant and preferable expel it externally into the atmosphere.

SAFETY REGULATIONS FOR SERVICE AND REPAIR WORK
8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall be t for the purpose and to the correct specication.
At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s
technical department for assistance. The following checks shall be applied to installations using ammable refrigerants.
• The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
• The ventilation machinery and outlets are operating adequately and are not obstructed;
• If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
• Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which
may corrode refrigerant containing components, unless the components are constructed of materials which are inherently
resistant to being corroded or are suitably protected against being so corroded.
9. Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures if a
fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall
be used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks shall include:
• That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• That there no live electrical components and wiring are exposed while charging, recovering or purging the system;
• That there is continuity of earth bonding.

Check the dehumidier for any transport damage. In case of damage, you should contact the seller immediately.
• Make sure that the dehumidier is standing rmly on a at surface.
• Make sure that the mains lead is easily accessible and is not
• Damaged by sharp edges or is crushed in any way during use.
• If any part of your house suffers from severe humidity, the
dehumidier can be placed there rst and then moved to another
part of the house later.
• Ensure the dehumidier is at a safe distance at least 50cm
away from a wall or furniture.
• Never place the dehumidier next to a radiator or heating
appliance.

OPERATING INSTRUCTIONS
Note:
• Ensure the supply power is in correspondence with the value on the nameplate.
• Ensure the water tank is correctly tted before the dehumidier can be switched on.
• If the dehumidier is turned off and then turned back on again immediately, it will take approximately 3 minutes to
reach full power (compressor back to work).
• If the dehumidier switched off by a power cut, it will automatically switch back on once the power is restored.
• The dehumidier works best at normal room temperature, its efciency is reduced if the ambient temperature falls to
below 15 .

The Energy Savings Smart Operation
When the target relative humidity is reached, the unit will operate only the fan in low speed for
1 minute, then will stop for 15 minutes. The fan will then run for 1 minute to check the relative
humidity.
If the relative humidity has risen above the target humidity (HS)+1%, the unit will start operat-
ing again. If the relative humidity remains below the target level, the unit will fall back to sleep
and only the fan works in low speed for about 1 minute and then stops for 15 minutes.
