Required Conditions Example Drawings
1. It is necessay to increase the pipe size between the first branch
kit and the final branch kit. (Reducers must be procured on site)
If the increased pipe size is larger than the main pipe size,
increase the main pipe size to the same as the increased size.
2. For calculation of Total extension length, the actual length of
above pipes must be doubled.
(except main pipe and the pipes that are not increased)
3. Indoor unit to the nearest branch kit < 130 ft.
4. The difference between
[Outside unit to the farthest indoor unit]
and [Outside unit to the nearest indoor unit] < 130 ft.
8 b +c+d+e+f+g+p< 295 ft.

φ5/8 > φ3/4
φ3/4 > φ7/8
φ7/8 > φ1*
φ1-1/8 > φ1-1/4*

How to calculate the
additional refrigerant
to be charged
Additional refrigerant to
be charged : R(lb)
R should be rounded
off in units of 0.1 lb.
R =
(Total length (ft)
of liquid piping
size at φ7/8)
(Total length (ft)
of liquid piping
size at φ5/8)
(Total length (ft)
of liquid piping
size at φ3/8)
(Total length (ft)
of liquid piping
size at φ3/4)

of liquid piping
size at φ1/2)

Note 1.
When the equivalent pipe length between outside and indoor units is 295 ft or more,
the size of main pipes (both gas side and liquid side (refer to figure 16)
must be increased according to the right table.
(Refer to figure 16)

4.First refrigerant branch kit
5.Indoor unit
Note 2.
Allowable length after the first refrigerant branch kit to indoor units is 130 ft or less, however it can be extended up to 295 ft
if all the following conditions are satisfied. (In case of “Branch with REFNET joint”)
