Example for Suction Pipe Selection:  

Cellar Plus 70-S3, outdoor unit mounted above indoor unit with vertical riser 4.5m and horizontal pipe run 7.4m, the suction line 

¾”

 OD is composed of 5pcs elbow 90

0

 long radius and 1pcs 180

0

 std radius.  

 
Read equivalent length from 

Table 7

 

Elbow 90

0

 long radius; 5 x 0.4 = 2.0m 

 

Elbow 180

0

 std radius; 1 x 1.0 = 1.0m 

 

Total pipe run = 7.4 + 4.5 = 11.9m 

Total equivalent length = 2.0 +1.0 +11.9 = 14.9m 
 
Read from 

Table 6

With total equivalent length 14.9m, the horizontal suction pipe selected based on column 20m, which is 

7/8” 

OD to minimize the 

capacity drop. 
 
In this example, if the outdoor unit is installed 

above

 the indoor (this is the most severe condition for oil return especially at low 

ambient and low room temperature). Suction riser must be selected based on column 10m, 

which is ¾” OD to ensure sufficient 

gas velocity to return oil to compressor.   

Note: If the outdoor unit installed below the indoor unit, the vertical pipe size follows the size of the horizontal pipe.  
 

Table 7: Equivalent Length for Fittings and Valve (in meter) 

 

 
 

Expansion Valve  

 

 

All evaporator models are pre-fitted with expansion 
valve TE2-02 in the piping, except JCC2-80EV which is 
supplied with two sizes of orifice as standard. Orifice 
size -03 is installed in the piping, and the orifice size -
04 was supplied loose (packed in a polybag tagged 
to the expansion valve body).  

 

The capillary tube label, which is in green color 
fastened around the capillary of expansion valve 
indicates the pre-fit orifice size (Example: 

Figure 8

 

indicates orifice size (04).  
 

Figure 8: Capillary Tube Label  

  
 
 
 
 
 
 

 

Refer 

Table 6

 

to change the orifice size in JCC2-80EV 

to match the coupled condensing unit. Follow 

Figure 9

 

to install the orifice.  

 

Installer is recommended to change the capillary tube 
label accordingly if orifice had been changed.  

 

Incorrect positioning of the sensing bulb will lead to the 
malfunctioning of the expansion valve. Refer 

Figure 10

 

for the correct sensing bulb orientation to suit different 
pipe diameters.   

 

Never mount the sensing bulb on the bottom side

 of 

the horizontal piping due to oil returning to the 
compressor may give false signal to the expansion 
valve. 

 

It is recommended to mount the sensing bulb on the 
horizontal pipe. If mount the sensing bulb at vertical 
pipe, the capillary tube must be pointing upwards to 
avoid malfunctioning of the expansion valve. 

 

Make sure the sensing bulb is far from the brazing or 
remove the sensing bulb before brazing.
