The refrigerant
WARNING:
Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacture.If repair is needed,please 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 “X”m2(see table 1).(only applies to appliances that are not fixed appliances)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s
instructions only.
Be aware that refrigerants may not contain an odour.
Read specialist’s manual.
Please read this operating manual carefully before operating the unit.
Appliance should be flled with flammable gas R32.
Before installing and using the appliance, read the owner's manual first
.
Before installing the appliance, read the installation manual first .
Before repairing the appliance, read the service manual first.
The figures in this manual may be different with the material objects, please refer
to the material objects for reference.

● 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 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.
Precautions
WARNING
● 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.

● All the work men who are engaging in the refrigeration system should bear the
valid certification awarded by the authoritative organization and the qualification
for dealing with the refrigeration system recognized by this industry. If it needs
other technician to maintain and repair the appliance, they should be supervised
by the person who bears the qualification for using the flammable refrigerant.
● It can only be repaired by the method suggested by the equipment’s manufacturer.

Installation notes
● The air conditioner is not allowed to use in a room that has running fire (such as fire
source, working coal gas ware, operating heater).
● It is not allowed to drill hole or burn the connection pipe.
● The air conditioner must be installed in a room that is larger than the minimum room
area. The minimum room area is shown on the nameplate or following table a.
● Leak test is a must after installation.
Maintenance notes
Welding
● Check whether the maintenance area or the room area meet the requirement of the
nameplate.
- It’s only allowed to be operated in the rooms that meet the requirement of the
nameplate.
● Check whether the maintenance area is well-ventilated.
- The continuous ventilation status should be kept during the operation process.
● Check whether there is fire source or potential fire source in the maintenance area.
- The naked flame is prohibited in the maintenance area; and the “no smoking”
warning board should be hanged.
● Check whether the appliance mark is in good condition.
- Replace the vague or damaged warning mark.
● If you should cut or weld the refrigerant system pipes in the process of maintaining,
please follow the steps as below:
