Connecting the Refrigerant Pipe

Refrigerant oil

Torque wrench

Flare nut

Union

Spanner

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 Before connecting the reprigerant pipe, open the cover side.

2 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 [mm(inch)] Torque (kgf•cm)

6.35 (1/4) 145~175

9.52

(3/8) 333~407

12.70

(1/2) 505~615

15.88

(5/8) 630~769

Must apply refrigerant oil on the flaring area to prevent

a leak.

Note

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

Cover side

 The designs and shape are subject to

change according to the model.



Connect the indoor and outdoor units using pipes with flared

connections(not supplied). For the lines, use insulated, unwelded,

degreased and deoxidized copper pipe,(Cu DHP type to ISO 1337),

suitable for operating pressures of at least 4200kPa and for a burst

pressure of at least 20700kPa. Copper pipe for hydro-sanitary

applications is completely unsuitable.



For sizing and limits (height difference, line length, max. bends,

refrigerant charge, etc.) see the outdoor unit installation manual.



All refrigerant connection must be accessible, in order to permit either

unit maintenance or removing it completely.
