5.2 Installation of accessory components
Installation on adjustable brackets:
„
The adjustable brackets must be installed before the device is attached to the ceiling.
„
Remove the plastic hood by removing the quick-release clips at the corners.
„
Remove the rigid brackets by drilling through the fastening rivet.
„
Attach the adjustable brackets by riveting and reattach the plastic hood.
5.3 heat exchanger connection
Heat exchangers with 1 row of pipes are not sensitive to the way feed and reflux are connected. Heat exchangers
with 2 or 3 rows of pipes must be connected according to the counter-current principle and depending on the
air outlet direction (vertical or horizontal).
Caution!
Hold the connectors in place with a suitable tool (e.g. pipe wrench) when connecting the heat exchanger to
prevent damage.
Attach pipes and connectors to ensure free access to the heat exchangers for maintenance purposes.
When temperatures below the freezing point occur, the heat exchanger must either be emptied and blown out
with compressed air or a standard anti-freeze with corrosion protection must be filled in to prevent damage due
to frost or corrosion!
