Oil trap

(suction tube)

There are two refrigerant pipes of different diameters:

◆ A smaller one(9.52mm, 3/8

) for the liquid refrigerant

◆ A larger one(19.05mm, 3/4

) for the gas refrigerant

◆ The thickness of tube should not less than 1.0mm.

◆ The inside of copper tube must be clean & has no dust.

The connection procedure for the refrigerant pipes varies according to

the exit position of the pipes from the indoor unit, as seen when facing

the indoor in the “A” side.

◆ Liquid refrigerant port

◆ Gas refrigerant port

◆ Drain hose connection port

◆ Drain pump hose connection port

Remove the protection caps 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.

Must use insulator which is thick enough to cover the refrigerant tube to

protect the condensate water on the outside of pipe falling onto the floor

and the efficiency of the unit will be better.

Cut off any excess foam insulation.

Be sure that there must be no crack or wave on the bended area.

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.

Shape an oil trap as shown in figure the oil trap must be formed every

level difference of 10m.

◆ If the pipes must be shortened refer to page 10.
