Venting the mixing and delivery vessel
WARNING
Danger of injury from escaping, spraying mix.
There may still be residual pressure in the mixing and delivery vessel after
the delivery process has ended. There is a risk that the mix is pulled along
with the escaping air during venting and that the vent is blocked.
−
Open the vessel vent slowly so that the pressure is reduced slowly.
Depending on the length of the delivery hose and/or delivery height, the
vessel pressure can rise to approx. 8 bar during the delivery process. At the
end of the delivery process, the vessel pressure drops automatically.
After the vessel pressure falls below 2 bar (fixed setting), the compressor
switches off. No further air is delivered by the compressor. The residual
pressure of 2 bar remains in the mixing and delivery vessel.
Therefore, before opening the dome cover, it must be ensured that the
mixing and delivery vessel is depressurized.
➢
As the vessel ventilation (1) locks the toggle lock, opening the dome
cover without prior ventilation is excluded by the design.
The mixing and delivery vessel can be vented at any time (even during
delivery). The procedure for venting during the delivery process (see Section
"Venting during the delivery process").
1.
Check the vessel pressure at the pressure gauges for the upper and
lower air.
➢
If a pressure gauge indicates pressure, the mixing and delivery
vessel must be vented.
