Check the air conditioner switch panel, air conditioner unit,
and condenser mounting areas for any abnormality, and check
hoses for any damage.
NOTE: When the season to use the air conditioner comes
close, check the air conditioner to get it ready to use at
all times. When not required to use the air conditioner
for a long period of time, operate the air conditioner
in the cooling mode once a week to prevent the lack of
lubrication.
Check the piping for abnormal deformation and/or damage. If
a pipe joint is contaminated with oil, refrigerant leakage may
be suspected. Check for leakage using a gas leak detector.
