MAINTENANCE

7-92

Check Air Conditioner
--- every 250 hours or 3 months

Check the air conditioner switch panel, air conditioner unit,
and condenser mounting areas for any abnormality, 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

WARNING: Do not clean the compressor and receiver

tank with steam.

The refrigerant gas pressure will increase, possibly
causing the hoses to break.

Check Air Conditioner Piping
--- every 250 hours or 3 months

d

CAUTION: If any leakage is found, repair or replace

the corresponding pipes. Tighten the joint bolts to
specification.

Do NOT overly tighten piping.

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.
