Safety Precautions for Refrigerant
● To realize the function of the air conditioner unit, a special
refrigerant circulates in the system. The used refrigerant is
the uoride 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 influence
upon the greenhouse effect is also lower. R32 has got very
good thermodynamic features which lead to a really high
energy efciency. The units therefore need a less lling.
WARNING
Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacture.
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

Safety Operation of Flammable Refrigerant
1. Qualification requirement for installation and
maintenance man
● 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
qualication for using the ammable refrigerant.
● It can only be repaired by the method suggested by the
equipments manufacturer.
2. Installation notes
● 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.
● It is not allowed to drill hole or burn the connection pipe.
● Leak test is a must after installation.
