side to the safety break. Under no circumstances
may the assembly torque be transferred to the
fuel dispenser connection.
Do not use pliers or pipe wrenches .
Use wrenches in the sizes specified .
Connect the hose to the safety break.
Torque to the hose coupling suppliers recom-
mended tightening torque. For Elaflex hose
assemblies LNG 13: 60 Nm, LNG 25: 150 Nm.
Do not use pliers.
Check sealing surfaces of connections.
Check if connections correspond in type and

The hose assembly is vented by a pressure
relief bore within the nozzle-sided safety break
part.

examine that the safety break and hose connec-
tions are tight under pressure and do not leak.
 NOTE: Pressurise system gradually while
checking for leaks.
