Pocket type filter
Pocket type filters are to be secured with fastening devices in the
mounting frame. For this, an air tight seating around the mounting
frame must be ensured.
Use the directions as provided with the filter for installing the
pocket type filter or channels, respectively, in the mounting frame.
For assembly, it must be observed that the pocket type filter is in its
correct position and that the filter surface will not pinch or clamp.
Damage or pressure marks on the filter surface are to be
avoided without fail, as otherwise the filter can rip during
operation and the filter category is no longer warranted.
Removable filters are to be installed sideways in the existing insert
tracks. It must be heeded that a seal is installed between the filters.
The continuous monitoring and cleaning of the filter is of great
importance and must be especially heeded, as a contaminated filter
will reduce air performance and, over a lengthy downtime,
represents an increased hygienic risk.

Heat exchanger connection
The heat exchanger is to be connected only in counter current flow,
as otherwise its performance can no longer be guaranteed.
Feed and return flow lines must be connected in such a manner that
no oscillation transfer and thermal stresses can occur.
Connections are to be made respective the „Feed line“, „Return line“
markings. Prior to making a connection, check sign positioning with
respect to the drawing and its function.
Flanges, connections and feed/return line shut-offs are to be
arranged in such a manner that the air filter can be removed without
excessive dismantling work.
A fault-free air bleeding and draining of the air heater and pipelines
is to be ensured by the user on-site.
When tightening the on site threaded connections on the heat
exchanger adapters, a pipe wrench should be used to carefully apply
a counter force, as the inner pipe may otherwise be twisted and
damaged.
In the event of frost hazard, the heat exchanger is to be protected
against freezing.
It must be assumed that residual water will remain in the heat
exchanger following normal drainage. For safety reasons, the heat
exchanger must additionally be purged with compressed air
(freezing hazard!).
4.12.
Droplet separator
The detachable cover should be removed for installing or de-
installing the droplet separator.
Droplet separator cartridges are hung on the upper slide rail and the
lower guide rail and pushed into, or pulled out of the unit,
respectively.
When installing the cartridges, the air flow direction arrow should be
observed.
4.13.
Steam heater connection
A safe condensate drainage must be continually ensured.
Controllability in partial load operation requires individual steam
registers to be outfitted with its own condensation drain.
