Auto Cut-Off & Depressurisation
When the target pressure has been reached, the display will show
“Fill Complete”. It is normal for the achieved pressure to reduce by up
to 5% after the fill has completed, particularly in smaller vessels. This
is due to the effect of cooling and flow losses. To compensate for this,
the user may wish to increase the target pressure, permitting that the
vessel is sufficiently rated.
DO NOT disconnect the vessel until the compressor has been
fully depressurised.
Depressurise the compressor by unscrewing the bleed screw; using a
rag for this is advised. Whilst depressurising, some moisture and
silicone may be expelled from the water separator.
Suitable precautions should be taken to protect any floor coverings
under the compressor.
The display will show the progress of the depressurisation.
When the compressor detects that the pressure is low (roughly below
70 BAR / 1015PSI) the display will return to the main menu.
The bleed screw should remain unscrewed to allow the compressor to
fully depressurise. After this, the vessel can be safely disconnected.
Lubrication check timeout
During long fills, the compressor will occasionally automatically stop
and request that the lubricant levels are checked.
At this time it is also necessary to fully bleed the water separator to
prevent excess moisture accumulation. If connected to a vessel
without a non-return valve, close the valve on the bottle and bleed the
compressor as described above. Users in particularly humid climates
may need to bleed the water separator more often.
