• Before test operation, the joint parts should not be heat insulated.
• Insert a flare nut into the pipe before flaring the pipe
• According to the following table to flare the pipe.
• After flared the pipe, the opening part must be seal by end cover or adhesive tape to avoid duct or exogenous
impurity come into the pipe.
• Be sure to use two spanners and proper torque to fasten the nut, too large torque will damage the bell mouthing,
and too small torque may cause leakage. Refer the following table for different pipe connec- tion.
• For horizontal refrigerant pipe, the distance be- tween supporters should not be exceed 1m.
• For vertical refrigerant pipe, the distance between supporters should not be exceed 1.5m.
