Note
■ These figures indicate the rate of change in capacity of a standard indoor unit system at maximum load under standard conditions.
(Moreover, under partial load conditions there is only a minor deviation from the rate of change in capacity shown in the above figures.)
■ With this outdoor(outside) unit, evaporating pressure constant control when cooling, and condensing pressure constant control
when heating is carried out.
■ If heat insulation of piping is insufficient, heat loss will become larger and capacity will decrease.
■ Method of calculating cooling / heating capacity = maximum cooling / heating capacity of outdoor(outside)units
= cooling / heating capacity of outdoor(outside) units obtained from capacity table x capacity correction factor due to piping length
to the farthest indoor unit.
■ Equivalent piping length for Y Branch and other pipes can be calculated with following table.

■ When the any one (or both ) of below conditions are satisfied, the diameter of main pipe must be increased.
- The equivalent length between outdoor(outside) unit and the farthest indoor unit is 90m or more
(Liquid or Gas pipes are increased in accordance with below table)
- The level difference (outdoor(outside) unit <-> Indoor unit) is 50m or more (Only liquid pipe is increased)
Refer to the table (Refrigerant pipe diameter from outdoor(outside) unit to first branch.) in the 'installation of outdoor(outside) units' part.
■ Read cooling / heating capacity rate of change in the above figures based on the following equivalent length.
Overall equivalent length = (equivalent length of main pipe) x correction factor + (equivalent length after first branching)
