4.4 Air Duct Connections
Before executing the final connection check the air ducts are
still clean. If necessary, clean the air ducts.
Only then connect the air ducts to the unit.
Connect the air ducts to the connections on top of the unit.
NOTE: Air ducts must be tightly connected to the unit - use
suitable accessories or sealing material. Insulation of the
fresh air and outgoing air ducts must be diffusion resistant.
4.5 Opening and Closing the Unit
The unit is equipped with a fixed front panel. For mounting
and maintenance work on the unit it is necessary to remove
the front panel.
IMPORTANT: Switch off the mains supply to the unit before
starting to work.
Remove the filters from the Atmosorb first, to enable removal
of the front panel.
Pull both filters out of the unit, see diagram 4.4
Remove the screw from the LH toggle-type fastener below the
unit.
Then open both toggle-type fasteners.
Pull the lower part of the front panel towards you.
Now lift the front panel above the top fixing points.
To close the unit, carry out the steps in reverse order.
IMPORTANT: Always ensure the screw is replaced into the
left hand toggle after re-assembly to avoid unauthorised
access to the unit.
