PULSE Installation, Commissioning and Servicing Manual - Revision 19
• Check that there is free rotation of swivel nut.
• Make sure the pawl and pawl spring are functioning correctly. The pawl should not be
interfering with the ratchet lugs on the swivel nut when the lever is inactive.
• Inspect the nozzle inlet swivel. The swivel should be secured by the grub screw through
the nozzle body.
• Check the free movement of the valve through the slide sleeve assembly when not
connected to an adaptor, (i.e., activate the lever several times) making sure there is
free movement forward and the valve returns to its inactive position. Remove the
swivel nut assembly and clean and lubricate component if movement is not free.
• Inspect the latch assembly making sure that the bushes are firmly attached to the latch
pin. The latch spring must hold the latch above the lever latch pin before latching.
• Fit a blanked adaptor firmly to the swivel nut. Activate the lever and check for valve
opening (There is usually an audible “click” on the DN Nozzle). Whilst the valve is
open, check for nose seal and “U” seal leakage using soapy water.
• Using soapy water check for leaks at the inlet swivel, nozzle body and valve assembly.
If there is seal leakage or component damage, it is recommended that the
associated seals be replaced.
Two Yearly Inspection�
It is recommended that a new Seal Kit be fitted throughout the nozzle. Whilst this may
seem extreme it will extend the life/service life of the nozzle and reduce the occurrence
of nozzle downtime in service.
Troubleshooting
In many instances problems can be dealt with by carrying one or more of the procedures
outlined in the above maintenance section.
2.2 Elaflex GG1DN / LPG
Maintenance
It is recommended that LPG nozzles be inspected every 6-12
months for any apparent physical damage to their components.
• Inspect swivel nut/nose piece seals for damage (e.g. cuts or
excessive wear).
