Unit placement
Make sure there is adequate room for access for installation and maintenance. Make sure that wiring of the
selected mains is equipped with a nearby disconnecting switch for maintenance.
NOTE: The unit is used only for suspended operation.
The unit is typically installed to false ceiling, but if this is not possible, it can be placed on a mezzanine or in
any suitable position. Make sure also that accessibility for control, exhaust outlets position and of the
electrical services must be taken into consideration.
It is the responsibility of the installer to ensure that all aspects of the system design are taken into account.
The system is designed as a ducted unit and should only be used in the presence of piping. Make sure the
pipes are supported along their entire length.
The unit has 4 nozzles, each of which is marked with a label. Make sure the correct piping is connected to
the appropriate outlets.
The ability to access the unit for maintenance must be taken into consideration. Fan maintenance and heat
exchanger cleaning should be performed annually. The filters must be cleaned as required.
PLEASE NOTE: Make sure to leave enough space to allow the cover to be removed and to provide
sufficient access for filter and heat exchanger maintenance.
NOZZLES
The unit is supplied with 120 mm nozzles. For satisfactory unit operation, make sure that the piping is
positioned as shown in the design diagram. Any change from the design diagram can cause an increase in
noise in use at maximum power.
NOTE: In situations where it is not possible or preferable to use 120 mm pipes, 100 mm pipes can be used
but PLEASE NOTE that noise levels will increase in "MAX" mode.
DRAINAGE
IIMPORTANT: The unit will sometimes produce condensate that MUST be discharged. The unit is equipped
with 2 drain connections. When using a condensate adapter, a 16 mm rigid plug-in pipe MUST be used.
IMPORTANT: When using flexible hoses for condensate, cut the condensate adapter and use the connector
of the straight hose supplied. Do not leave folds in the condensate hose.
The unit is equipped with an anti-flooding condensate collection device.
NOTE: The fan will stop and an ALARM! will appear on the display if the condensate drainage path is
blocked and the unit goes into anti-flooding mode.
