When refrigerant leaks or required discharge during installation, maintenance, or disassembly, it should be
handled by certified professionals or otherwise in compliance with local laws and regulations.
Please read this manual carefully before operating the unit.
The Refrigerant
An air conditioner operates by circulating a refrigerant inside a closed system to remove heat and humidity from the
indoor air. Before a refrigerant is inserted into the unit at the factory it is cleaned to ensure efficient operation. Inside
this unit is R32, a flammable, odorless, fluoride-based refrigerant. Furthermore, it can lead to explosion under certain
conditions. The flammability of R32 is very low and can only be ignited by flame.
Compared with 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. The units therefore need less refrigerant contained within.
WARNING:
•
Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction.
•
Do not use means to accelerate the defrosting process or to clean, other than those recommended by the
manufacture. Should a repair be needed, contact a local licensed service technician.
•
Any repairs carried out by unqualified personnel may be dangerous.
•
Piping and keep open flames and hot items away from unit
•
Appliance should be installed, operated and stored in a room on a stable area.
•
A
ppliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s instructions only.
•
Be aware that refrigerants may not contain an odour.
•
The appliance should be stored in a room without continuously operating ignition sources. For example: open
flames, an operating gas appliance or an operating electric heater.
•
Do no pierce or burn. Be aware that refrigerants may not contain an odor.
•
Adopt R32 flammable refrigerant. When maintaining or deposing the unit, the refrigerant inside the system must
be recovered
. Refrigerant should be recovered, which can’t be discharged freely.
•
Keep ventilation opening clear of obstruction.
•
The unit can only be maintained according to the method suggested by manufacturer.
•
Appliance should be stored in a room without continuously operating open flames (eg: an operating gas appliance)
and ignition sources (eg: an operating electric heater) close to the appliance. No open fire (fired equipment such
as electrical heater and gas stove etc.) or any equipment (eg: switch) that might generate arc around the
appliance.
•
The appliance should be stored so as to prevent mechanical damage from occurring.
