2.6 Combinations and capacities of the outdoor units and
indoor units
CAUTION
Install the indoor units that correspond to indoor air conditioning load.
Otherwise, the units frequently repeat start and stop. That could result in
breakdown of the units.
The number and total capacity of the connected indoor units must be within the
range shown below.
Connecting indoor units out of this range could result in breakdown.
•
In a combination in which the total capacity of the connected indoor units exceeds the capacity of the
outdoor unit, the performance of each indoor unit will be lower than its rated capacity when all indoor
units are operated simultaneously. Always strive to keep the total capacity of the indoor units within the
outdoor unit capacity.
•
Permissible piping length is restricted up to 100 m. (actual length), and total piping length is restricted up
to 350 m. when the total capacityof the connected outdoor unit exceeds 130% of rated capacity.
•
Connectable indoor units are P22 to P280.
