Caution
The CU-3C20BKP5G/C9BKPG have different cooling capacities depending on the connection to A
1
,A
2
and/or B on CU-
3C20BKP5G individually.
(Refer to SPECIFICATIONS on CATALOG)
1. The Cooling Capacity of Indoor Unit connecting “B” on CU-3C20BKP5G (Called B unit) is different from that of A
1
and
A
2
Units.
2. A
1
and A
2
Units share the same compressor, their cooling capacities thus change depending on whether one, the other,
or both of the units is in use.
3. Reflect the B or A (A
1
and/or A
2
) on the Indoor Unit for later reference.
