CORRECTION FACTORS
Piping Length Factor Chart
The correction factor of height between each indoor unit and outdoor unit
NOT E :
To ensure correct unit selec tion, co nsider the farthest indoo r unit.
16ft(5m)
32.8ft( 10m) 49ft(15m) 66ft(20m ) 82ft(25m )
98ft(30m )

2. Be sure to minimize length of connection pipes to optimiz e performance. If the outdoor unit is
installed higher or lower than the indoor unit, it is necessary to apply height correction factor
additionally to length correction factor to calculat e cooling/heating.
If outdoor unit is higher, correction should be applie d to cooling capacity, if outdoor unit is lower,
correction should be applied to heatin g capacity.
The above data reects that the minimum height requirements have been meet or exceeded
during the installation. The
height dierence between the indoor and outdoor unit is based
at 0ft/0m. Using reference chart above to calculate proper unit capacity.
