For all the faults requiring welding the refrigeration pipelines or components inside the refrigeration system of R32 refrigerant
air conditioners, maintenance at the user's site is never allowed.
For the faults requiring radical disassembly and bending operation of the heat exchanger, such as the replacement of the
outdoor unit chassis and integral disassembly of the condenser, inspection and maintenance at the user's site are never
allowed.
For the faults requiring replacement of the compressor or parts & components of refrigeration system, maintenance at the
user's site is not allowed.
For other faults not involved in the refrigerant container, internal refrigeration pipelines and refrigeration elements, the
maintenance at the user's site is allowed, including the cleaning and dredging of the refrigeration system requiring no
disassembly of refrigeration elements and no welding.
In case replacement of gas/liquid pipes is required during maintenance, the joint of evaporator gas/liquid pipes of the indoor
unit shall be cut off with a cutting knife. Connection is only allowed after re-flaring (the same to the outdoor unit).
Note: in case relocation is required, the joint of evaporator gas/liquid pipes of the indoor unit shall be cut off with a cutting knife.
Connection is only allowed after re-flaring (the same to the outdoor unit).

required in the assessment regulations.
2. The equipment can only be maintained and repaired as per the method recommended by the manufacturer. In case the
assistance from personnel of other disciplines is required, the assistance shall be supervised by the personnel with qualification
certificate involved in flammable refrigerant.
Please call the dealer or the appointed agency.
