The refrigerant
WARNING
Appliance should be flled with flammable gas R32.
Before installing and using the appliance, read the owner's manual first.
Before repairing the appliance, read the service manual first.
Before installing the appliance, read the installation manual first.
● 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 lead to explosion undercertain conditions. But the flammability of the
refrigerant is very low. It can be ignited only by fire.
● Compared to common refrigerants, R32 is a nonpolluting refrigerant with no
harm to the ozonosphere. The influence upon the greenhouse effect is also
lower. R32 has got very good thermodynamic features which lead to a really
high energy efficiency. Therefore, these devices require less filling.
Do not use means to accelerate the defrosting process or to clean, other
than those recommended by the manufacture. If repair is needed, 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 continuously operating ignition sources. (For example: open flames,
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 Xm2. (Please referto table “a” in section of “Safety operation of
flammable refrigerant” for Space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow
manufacturer’s instructions only. Be aware that the refrigerant may not
contain odor. Read the expert manual.

WARNING
Operation and maintenance
● 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
knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe
way and understand the hazards involved.
● Children shall not play with the appliance.
● Cleaning and user maintenance shall not be made
by children without supervision.
● Do not connect air conditioner to multi-purpose
socket. Otherwise, it may cause fire hazard.
● Do disconnect power supply when cleaning air
conditioner. Otherwise, it may cause electric shock.
● If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
● Do not wash the air conditioner with water to avoid
electric shock.
● Do not spray water on indoor unit. It may cause
electric shock or malfunction.
● After removing the filter, do not touch fins to avoid
injury.
● Do not use fire or hair dryer to dry the filter to avoid
deformation or fire hazard.
