LPG DRY BREAKS
Each LPG hose is fitted with a reusable dry break coupling
designed to seal off the outflow of LPG in the event of a
drive-off incident.
During the reassembling procedure described below care
must be taken to ensure the U-Bolt is not too tight to avoid
deforming the break. There should be free up and down
movement of the ring.
Reassembly After Separation
This work must be completed by authorised personnel.
1. Switch off pump. Check for damage to the dispenser, hose and nozzle.
The reassembly can take place under pressure.
2. Push break sleeve back over the break-away part and hose fitting.
3. Clean all parts and check them for damages like damaged sealing surfaces of the
break-away part, deformations, broken plastic parts or damaged lanyard.
With such damage, the coupling must be exchanged.
4. Slightly lubricate the O-Ring within the body.
5. Push back the sliding sleeve of the body an hold it.
6. Fit the break-away part into the body. No force is necessary.
7. Release the sliding sleeve - it remains in its position. Now push the break-away part
in firmly to the limit. The sliding sleeve will snap back.
Check the coupling for tightness.
8. Push break sleeve over the coupling and let it snap in.
