Check Air Conditioner
--- every 6 months
Check the air conditioner switch panel, air conditioner unit,
and condenser mounting areas for any troubles, and check
hoses for any damage.
f
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 lack of lubrication.
d
CAUTION: Avoid steam cleaning
Do not clean the compressor and receiver tank
with steam. The high temperature will cause the
refrigerant gas pressure to increase, possibly
causing the hoses to break. This could injure
personnel.
Check Air Conditioner Piping
--- every 6 months
d
IMPORTANT: If any leakage is found, repair or
replace the corresponding pipes. Tighten the joint
bolts to specification.
Check the piping for deformation and/or damage. If a pipe
joint is contaminated with oil, refrigerant leakage may be
suspected. Check for leakage using a refrigerant gas leak
detector.
