2. System overview
The Ozone Modules within the EOZ chassis produce ozone gas. Ozone (O3) is a very eective oxidant, and when
mixed into a kitchen exhaust airstream it breaks down grease and odor particles to water vapor, carbon dioxide
and dry minerals, all natural products of oxidation which exit the exhaust system.
Note! For best results with odor reduction, the reaction time for ozone within a kitchen exhaust system should
be at least two seconds. However, longer exposure can further improve results. This time should be taken into
account during the design phase of the kitchen exhaust system
Installation method
ATTN! EOZ must be installed in the correct orientation. The direction of the airflow must correspond
ATTENTION!
• During the installation, keep in mind to leave the service area free of obstructions for ease of future
maintenance.
• EOZ chassis can be mounted in any position. It is very important to keep in mind that the direction of the
airflow must correspond with the arrow on the EOZ chassis as shown below.
• All duct installation materials between the outlet of the EOZ unit and the main exhaust duct, including
screws, rivets and the connecting flange, must be stainless steel (AISI 316 ).

Control Panel and EOZ data wiring
There are three cables that must be connected to the Control Panel. Data cable (3x0,25mm2) for communication
between Control Panel and EOZ unit, I/O cable (5x0,5mm²) for connecting to the building automation and LAN
cable to access the Control Panel via internet.
Wiring Control Panel to the EOZ unit is done with 3x0,25 mm² shielded data cable.
Begin by installing the EOZ data cable between the EOZ unit and the Control Panel. Note the colors of the wires
used when connecting the three terminals A, B+ and C.
Next, connect the cable to the EOZ as shown below. Ensure that the cable color used for each terminal is
the same on both devices.

®NORDcanopy |EOZ installation guide
The max number of Ozone Modules connected to a single Control Panel is 99, with a maximum length of 500m.
However, it may be advantageous to have multiple Control Panels in larger facilities for local monitoring purposes.
To connect multiple EOZ and/or Ozone Modules together they must be connected sequentially (“daisy-chained”)
from the Control Panel to the nearest device, then to next and so on. However, please note that although the
physical cabling is “chained” from one device to the next, the data cables are connected in a parallel format. In
this way data communications between devices will remain active even if one of them is powered o,
malfunctioning, or unplugged and removed.
Thus, each A, B+ and C data wire leading in from devices of any EOZ in the chain should share the same terminal
screw in its respective connector.
NOTE! The following section applies only when installing multiple EOZ or Ozone Modules. If
installing only one unit, please skip to section “Control Panel and I/O wiring”.

7. Setting Ozone Module addresses
All Ozone Modules connected to the same Control Panel must be set to a unique device address. The Ozone
Module(s) inside of an EOZ chassis have been set at the factory to the following specifications:
EOZ-1: Device address is “3”
EOZ-2: Device addresses are “1” and “2”
For installations with multiple EOZ units, it is important to ensure that there are no overlapping address conflicts:
* All Ozone Modules in each EOZ chassis or canopy must have a unique device address.
* Address identification labels must be added to the service hatch on EOZ units. In case of model EOZ-2, both
address labels must be placed upon the unit.
Opening EOZ hatch
Start by opening the front panel by opening two (2) clamps that are holding the panel.
NOTE! The following section applies only when installing multiple EOZ units. If installing only one unit,
the Ozone Module addresses do not need to be changed and you may skip this section.
NOTE! Turn o and disconnect the electrical power cord from the EOZ chassis before proceeding.
