Possibility of Failure & Checkpoint
Check
There is a possibility of light injure or loss of
property.
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.
