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.
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.
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
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.
