Samsung DH60 T Series Installation Manual

Connecting the Indoor Unit Assembly PipingENGLISHE-19There are two refrigerant pipes of differing 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 tothe exit position of the pipes from the indoor unit, as seen when facingthe indoor in the “A” side. Liquid refrigerant port Gas refrigerant port Drain hose connection portRemove the pinch pipe on the pipes and connect the assembly pipes toeach pipe, tightening the nuts, first manually and then with a torquewrench, a spanner applying the following torque.Must use insulator which is thick enough to cover the refrigerant tube toprotect the condensate water on the outside of pipe falling onto the floorand the efficiency of the unit will be better.12Cut off any excess foam insulation.3Be sure that there must be no crack or wave on the bended area.4It would be necessary to double the insulation thickness (10mm or more)to prevent condensation even on the insulator when if the installed area iswarm and humid.5Shape an oil trap as shown in figure the oil trap must be formed everylevel difference of 10m.6 If the pipes must be shortened refer to page 18.NNNN oooo tttt eeeeOuter Diameter Torque9.52 mm (3/8") 250~280 kgf•cm19.05 mm (3/4") 990~1210 kgf•cmIndoor unitOutdoor unit Oil trap (Must be installevery 10m)a.
