12. SERVICE PROCEDURES

Tubing precautions

Refrigerant R410A is more easily affected by dust or moisture compared to R22, thus be sure to temporarily

cover the ends of the tubing with caps or tape prior to installation.

Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners

with R410A are subject to higher pressure than those using R22 and R407C.

No addition of compressor oil for R410A

No additional charge of compressor oil is required.

No use of refrigerant other than R410A

Never use a refrigerant other than R410A.

If refrigerant R410A is exposed to fire

Through welding, etc., toxic gas may be released when R410A refrigerant is exposed to fire. Therefore, be

sure to provide ample ventilation during installation work.

Caution in case of R410A leak

Check for possible leak points with the special leak detector for R410A. If a leak occurs inside the room,

immediately provide thorough ventilation.
