□
Check Possibility of Failure & Checkpoint
□
There is a possibility of light injure or loss of
property.
□
The unit is inoperated or the refrigerant flows
into the inoperative unit and the leakage is
expected. Check if there is a wrong tubing or wiring
□
connection with another system.
□
□
□
Power failure or short circuit may cause electric
shock or fire. Check installation work and ground
□
wire work.
□
□
If the gas leakage occurs, the unit quality not only
□
becomes inferior but affects environment. Repair it
as quickly as possible.
□
The resin portion cracks after a few months and it
may cause water drain.
□
Since there is a possibility of water drain, repair the
□
drain pipe if the drain failure or water drain occurs.
The quality of unit not only becomes inferior but
□
there is a possibility of the water drain. So, perform
the heat insulation work properly.
□
Check if there is a fan contact or distortion of the
indoor unit.
Check if the unit does not operate or there is a
□
wrong tubing or wiring connection with another
system.
