1.4.2 Preventing leakages

● Do not let air enter the refrigeration cycle, because this will increase the risk of
explosion and injury due to high tension inside the refrigerant cycle.
● Keep all tubing runs as short as possible.
● Use the fl are method for connecting tubing and apply refrigerant lubricant to the
matching surfaces of the fl are and union tubes before connecting them, then tigh-
ten the nut with a torque wrench for a leak-free connection.
● Do not leak refrigerant while working on the refrigerant tubes during installation,
maintenance or repair.
● Check carefully for leaks (see → 1.4.3 Detecting leaks) before starting the test run.
