Installation information
The units are delivered fully assembled. To facilitate handling, they can be
taken apart and reassembled in the installation room.
With the version for disassembly, the frame sections split in the centre and are
secured with a flat steel bar or angle bracket (secured with screws).
To split the KG 40-100, remove any frame insulation that is in place and refit
after the cubes have been assembled.
Please note The fan shaft must always be horizontal.
With fans mounted on anti-vibration spring mounts, remove the transport brackets.
When installing, ensure that the distance between the connection flanges is

not greater than 100 mm, to enable the canvas flange to move fully.
brackets
The canvas flange and louvre damper may need to be insulated on site against
both sound emission and the formation of condensate.
The heat exchangers (cooler, heater) operate using the countercurrent principle,
i.e. the heat transfer medium or refrigerant is channelled in the opposite direction
to the air flow. The relevant flow connection is therefore always located on the
air discharge side of the heat exchanger.
The heat exchangers must be connected in such a way that no mechanical
Please note
stress from the pipework is transferred to the heat exchangers.
Furthermore, the transmission of vibrations and thermal expansion between
the air handling unit and the pipework must be reliably prevented.
Ensure that the connection lines do not hinder access to other parts of the unit
(fan, filter, scrubber, etc.).
Regarding the heat exchanger (with flange), we recommend making the
connection with bends, so that the heat exchanger and mist eliminator can
later be extracted from the side for cleaning.
With steam coils, always arrange the steam intake at the top (large connection ø)
and the condensate drain at the bottom.
When connecting the flow and return lines, counterhold the threaded heat
exchanger connectors to prevent them from being twisted, otherwise the
application of mechanical force may detach the collector from the heat exchanger.
This would destroy the heat exchanger.
Please note Ensure there are ventilation and drainage facilities on site.
Connect a siphon to the condensate drain connector on the cooler pan.
The connection pipes outside the external casing are insulated on site.
