Chapter XI Maintenance
● To place the unit in outage, first stop the air conditioner and then turn off power switch.
● After long operation of outdoor unit, dust will accumulate on surface of heat exchanger,
lowering heat transfer efficiency and hence unit performance. Use long hair brush or
compressor air to clean such surface.
● Cleaning cycle of indoor strainer depends on installation position and environment.
Frequently clean indoor strainer to avoid failure.
Indoor units of FR(D)95, FR(D)125/S, FR(D)180/S, FR(D)260/S, FR95-C and FR125-C/S
are complete with strainer. Indoor units of other models are not complete with strainer; hence
return air grating with strainer must be used.
Method to remove strainer of indoor units of FR(D)95, FR(D)125/S, FR(D)180/S,
FR(D)260/S, FR95-C and FR125-C/S:
① Remove reserved seal plate on return air duct;
② Lightly push strainer upward, move limiting chute out, and lightly remove strainer from
