any.

Check whether the ground wire is connected properly.

Check whether the insulation work of refrigerant circuit and ventilating duct is on sound

status.

Check whether the installing seat is corroded or rusted.



Startup



Connect the indoor unit 12 hours after connect the outdoor unit to power supply.



Maintenance and upkeep of outdoor unit



The edge of some sheet metal assemblies and the fin of the condenser are very sharp.

Incorrect operation may cause harm. Be cautious when cleaning them up.



Check the air inlet and outlet of the outdoor unit periodically to see whether they are

blocked by stain or lampblack.
