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 )

0.7 
1. Above data is assuming  that the height  difference between indoor unit and  outdoor  unit is 0ft/0m.
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.
