Connecting the Refrigerant Pipe
ENGLISH
There are two refrigerant pipes of differing diameters:
A smaller one for the liquid refrigerant
A larger one for the gas refrigerant
The inside of copper pipe must be clean & has no dust.
1
Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque wrench,
a spanner applying the following torque.
Outer Diameter
Torque (kgf•cm)
9.52 mm (3/8")
12.70 mm (1/2")
15.88 mm (5/8")
19.05 mm (3/4")
22.23 mm (7/8")
250~280
380~420
440~480
990~1210
990~1210
Note
If the pipes must be shortened refer to page 10.
2
Must use insulator which is thick enough to cover the refrigerant pipe to
protect the condensate water on the outside of pipe falling onto the floor
and the efficiency of the unit will be better.
3
Cut off any excess foam insulation.
4
Be sure that there must be no crack or wave on the bended area.
5
It would be necessary to double the insulation thickness (10mm or more)
to prevent condensation even on the insulator when if the installed area is
warm and humid.
