Check Before Installation
Unpacking Check
①
After unpacking, check whether the packing materials are in good
condition, whether the accessories that come with the product are
complete, whether the air conditioner is intact, whether the surfaces of
the heat exchanger and other parts are not worn, and whether there
are oil stains on the stop valves of the unit.
①
Check the two sealing nuts of the refrigerant pipe, and observe whether
the red dot on the surface of the sealing nut of the gas pipe bulges. If it
bulges, the refrigerant system is well sealed; if it retracts, it is leaking,
and need to contact local dealer.
①
Check the model before installation.

After indoor unit and outdoor unit inspection, pack them with plastic
bags to avoid intake of foreign matters.
