Notes on installation
The fan shaft must always be horizontal.
Caution
Remember to remove the transportation locking devices of fans mounted on
vibration damper springs.
Locking
When installing, bear in mind that the maximum permissible distance between the
devices
connecting flanges is 100 mm, in order to ensure that the sailcloth adapter has
full freedom of movement.
Sailcloth adapters might require on-site insulation against acoustic emissions
and condensation.
The heat exchangers (chillers, heaters) work on the counter-flow principle, in other
words the heating or chilling medium flows in the direction opposite to that of the
airstream. This, in turn, means that the flow connection for the medium is always
situated on the air-outlet side of the heat exchanger.
Connect the heat exchangers in such a way that no mechanical stresses and
Caution
strains from the piping system are transferred to the heat exchangers.
Also provide reliable means of preventing the transmission of vibration from air-
conditioning unit to piping system.
Make sure that the connecting pipework does not hinder access to other parts of
the air-conditioning unit (fan, filter, washer, etc.).
The steam inlet of steam registers is always at the top (large-diameter port) and
the condensate drain must always be at the bottom.
When connecting the flow and return pipes, always counter-hold the threaded
Caution
adapters of the heat exchanger to avoid torsional loading.
Make sure that adequate provision is made on site for bleeding and draining.
Make sure that a siphon is connected to the condensate drain of the chiller tray.
Outside the skinning panels, the pipes must be insulated on site.
Remove the side panel and remove the drip separator with condensate tray (the unit
is shipped with the drip separator located in the guide rails).
Run a bead of sealing compound around the drip-separator frame and secure it to the chiller
element.
Caution: Make sure that the condensate drain apertures of the drip separator are at
the bottom.
Secure the clip-on shield to the collector side of the chiller element at the air inlet: note
that the arrangement depends on the direction of air flow.
Arrangement of components along the direction of air flow:
Chiller element, drip separator, condensate drain.
Slide the fully assembled unit into the chiller section; the chiller element is held in the
guides.
Reinstall the side panel.
