Re oxygenizing unit
The fan speed of the re oxygenizing unit is controlled by the circuit of the filter unit, and is in relation to the
speed of the fan speed selected for the filter unit.
For specific needs, it is possible to modify the performance of the re oxygenizing unit by connecting the
brown cable (6) to one of the other available terminals: white, red, orange.

The ducting connecting the re oxygenizing unit to the external
air inlet is very long and the resistance in the ducting requires
more fan power. The resulting air being provided depends on
the resistance of the ducting.
The re oxygenizing unit may be
mounted on the filter unit or
separate. In both cases it is
necessary to connect the fan motor
of the re oxygenizing unit to the
electrical terminals of the filter unit.
1) Open the filter unit contacts
cover plate removing the fixing
screws
2) Remove the inspection plate of
the re oxygenizing unit
3) Open the junction box at the
inside of the re oxygenizing unit
4) Use a 3G1.5 cable with suitable
cable glands
5) Connect terminals 4-5-6 of the
filter unit to the terminals in the
re oxygenizing unit as follows:
(4) blue to neutral
(5) yellow-green to earth
(6) brown to 3rd speed (grey)
