When carrying on theleakage check and test, do not mix in the oxygen, theacetylene and flammable and the reactive gas, thesegases are quite dangerous, and may possibly causeexplosion. It is suggested that the compressed air,the nitrogen or the refrigerant is used to performthese experiments.4.1 The Tube Material(1) Prepare the copper Tube on the spot.(2) Choose dustless, non-humid, clean copper tube.Before installing the tube, use nitrogen or dry air toblow away the tube dust and impurity.(3) Choose the copper tube according to Fig. 4.2.4.2 Tubing connection(1) The connection positions of the tube are shown inFig. 4.1 and Fig. 4.2.unit: (mm)The tube can be connected from three differentdirections.
