WARNING
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer. Should repair be necessary, contact your nearest
authorized service centre. Any repairs carried out by unqualified personnel may be
dangerous. The appliance shall be stored in a room without continuous operating ignition
sources. (for example: open ames, an operating gas appliance or an operating electric
heater.) Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger
than Xm .(Please refer to table “a” in section of “ Safety Operation of Inflammable
Refrigerant” for space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s
instructions only. Be aware that refrigrants not contain odour. Read specialist’s manual.
If a stationary appliance is not tted with a supply cord and a plug, or with other means
for disconnection from the supply mains having a contact separation in all poles that
provides full disconnection under overvoltage category III conditions, the instructions
shall state that means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and

To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.The
refrigerant is flammable and inodorous. Furthermore, it can leads to explosion under
certain conditions. But the flammability of the refrigerant is very low. It can be ignited
only by re.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to
the ozonosphere. The inuence upon the C&Hnhouse effect is also lower. R32 has got
very good thermodynamic features which lead to a really high energy efficiency. The
units therefore need a less lling.
Before installation, please check if the adopted power is accordance with that listed on
nameplate, and check the safety of power.
The unit shall contact with the supply mains by a full disconnection device under
overvoltage category Ⅲ.
Before using, please check and confirm if wires and water pipes are connected
correctly to avoid water leakage, electric shock or re etc.
Don’t operate the unit with wet hand, and don’t allow children to operate the unit.
The On/off in the instruction is for the operation to on and off button of PCB for users;
cut off power means to stop supplying power to the unit.
Don’t directly expose the unit under the corrosive ambient with water or dampness.
Don’t operate the unit without water in water tank .The air outlet/inlet of unit cannot be
blocked by other objects.
The water in unit and pipeline should be discharged if the unit is not in use, to prevent
the water tank, pipe line and water pump from frost-cracking.
Never press the button with sharp objects to protect manual controller. Never use
other wires instead of special communication line of the unit to protect control elements.
Never clean the manual controller with benzene, thinner or chemical cloth to avoid
fading of surface and failure of elements. Clean the unit with the cloth soaked in neutral
eradicator. Slightly clean the display screen and connecting parts to avoid fading.
The power cord must be separated with the communication line.
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
authorises their competence to handle refrigerants safely in accordance with an industry
recognised 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 flammable
refrigerants.
