16 Helix LPG - IEC
This information is applicable to Helix 1000 LPG, Helix 6000 LPG and Helix
6000 B2B LPG.
Most images in this chapter show Helix 1000 LPG but Helix 6000 LPG and Helix 6000 B2B LPG
are almost similar.
BEFORE REPLACING ANY COMPONENTS:
We recommend to completely discharge the pressure in the liquid and gaseous lines, before
any operation is carried out, using inertial compressed gas (NITROGEN, ARGON, HELIUM or
similar) which when injected into the dispenser circuit will remove the explosion hazard (poten-
tially explosive atmosphere). A typical nitrogen cylinder of a medium volume of 20 L is suitable.
Close in ground inlet valve so that the dispenser is disconnected from the storage tank.
No pressure must be present when working on the hydraulic circuit.
LPG is a liquefied gas fuel under high pressure (typical working pressure is about 10-18 bars).
WARNING!
High Pressure
LPG is a liquefied gas fuel under high pressure (typical working
pressure is about 10-18 bars).
During the service, the technician must ensure that the dispenser, and/ or the area where the
technician is working, is de-pressurized by the relief valves.
When releasing pressure, the gas will become very cold, therefore, take the necessary precautions
to avoid bodily injuries due to freezing.
WARNING!
Cold Gas
When releasing pressure, the gas will become very cold,
therefore, use protective gear, gloves, etc., to avoid bodily in-
juries.
Inspect all connections for leaks.
