Add new drying agent.
The filling of drying agent in these vessels comprises 3 different layers of drying
and cleaning agent. These different layers assure a constant dewpoint.
Together with the drying agent, the gaskets and the solids filter in the
vessels/hoppers should also be replaced.
Risk of falls!
The dryer must not be misused as a climbing aid! The components have
not been designed for such loads and could fracture.
Only use approved climbing aids when filling the container.
► Dismantle upper pipe bridge and connection to
downstream filter (also refer to page 48).
► Fill the several drying agents in as separate layers
(according to the technical data in the appendix).
► If necessary, use a funnel. Take special note of the
next step.
► Ensure for a high bulk density in the vessel.
► Failing that, when filling the drying agent, use a stick
to distribute and compact it.
► Repeat the process on the second vessel.
► Then reinstall the pipe bridge and connection to the
downstream filter.
► Restart dryer (see page 40). Check that the connection is leak tight.
Note:
To achieve an optimum bulk density, we recommend using a
"Snowstorm" filling pipe available from the manufacturer.
