NOTE
1. The total capacity(in Btu/h unit) of con-
nected indoor unit models represents
the total sum of the figures expressed in
the indoor model name.
2. Combinations in which the total capacity
of the connected indoor units exceeds
the capacity of the outdoor unit will re-
duce the capacity of each indoor unit
below the rated capacity during simulta-
neous operation. Therefore, if circum-
stances allows, combine indoor units
within the capacity of the outdoor unit.
3. VAHU, Ceiling Concealed Duct(High
Static) type indoor unit's combination
calculation method as below.
Calculation method for total capacity of
connectable indoor unit to an outdoor
unit
= (Sum of all VAHU & Ceiling Concealed
