Checking the Sealing of the Solenoid
 Connect the loading post to a full tank.
 Close the Outlet valve (IV2)
 Without pressing the start button, degass
the lines between the solenoid valve and the
outlet valve using the bleed valve (Bv1).
 Close the bleed valve (Bv1) and observe
the outlet pressure gauge to see if the
pressure rises. If you see a rise in pressure,
the solenoid valve is leaking.
Checking the Post for Leaks
Before you start, make sure you have:
 Soapy water
To check the post for leaks:
Be careful not to spray or
drip water into any electronics when
checking for leaks.
1. Make sure the outlet valve is closed.
2. Connect the post to a tank and
commence a fill until you see pressure
on both the inlet and outlet gauges.
3. Stop the fill
4. Apply soapy water to all joins in the
assemblies and fittings on the inside
and outside of the loading post,
including the hose.
If bubbles form, there is a leak with that
assembly or fitting. The fitting may
require tightening or the seals might
need to be replaced.
You must isolate the gas
supply and depressurise the post
before disassembling any component
or adjusting any fitting. Serious injury
may result if components are removed
while the post is under pressure.
5. After checking for leaks, wipe any
excess water off the loading post to
prevent corrosion.
