IMPORTANT

These air conditioners employ new
refrigerant R410A.

Pay special attention when
servicing the unit.

4-room multi Outdoor unit

< Combined Indoor Units >

1. How these units may be combined is given in

the Unit Combination Tables in the Appendix.

2. Be sure to operate the air conditioning

system only when 2 or more indoor units

have been installed. If operated with only a

single unit installed, the returning fluid to the

compressor may cause a malfunction.
