Safety notes
This manual consists of important information on the instruction and safety of External Ozone Cleaning System.
Read this manual carefully before installing, commissioning, or performing maintenance or repair work on the
system.
• Always wear appropriate protective clothing when handling the equipment.
• External Ozone Cleaning System is intended only for the treatment of exhaust air as described in these
instructions.
• External Ozone Cleaning System uses high voltage to create an electric charge that generates ozone
(O₃). Ozone significantly reduces odor, grease, mold and bacteria. ETS NORD AS disclaims any liability
in the case that the product is not used in accordance with the manufacturer’s instructions contained in
this manual.

2. System overview
The Ozone Modules within the EOZ chassis produce ozone gas. Ozone (O3) is a very eective 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 ).

3. Mount the EOZ
The EOZ unit may be installed in any convenient location in the kitchen space, ideally with easy access to supply
air and within 3m of the canopy connection to the exhaust duct.
Keep in mind, however, that 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).
Hanging the EOZ chassis
Begin by mounting four (4) M8 threaded rods to the ceiling. Suspend the EOZ unit from the rods with M8 nuts
and washers as shown . Adjust height as needed.
NOTE! Direction of the airflow must correspond with the arrow on the EOZ.

Connect to the ventilation ducts
After the EOZ unit has been securely attached to the ceiling, connect the supply air and exhaust air ducts.
Note: Materials for the supply air side may be chosen at the discretion of the installer. However, all materials
used 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).
Secure the ducts with stainless steel rivets or sheet metal screws from both sides and ensure the connection
is airtight.

Connect the pressure measurement hose to the exhaust duct
Begin by installing the measurement nozzle onto the exhaust duct or canopy exhaust chamber with a stainless
steel rivet or sheet metal screw. Mount the nozzle to the exhaust duct ahead of the EOZ connection pipe as
shown below.
Next, fasten one end of the long measurement hose provided with the shipment to the newly installed
measurement nozzle. Trim the hose to an appropriate length and run the free end of the hose to the right
measurement nozzle on the EOZ unit as shown below.
NOTE! This hose must be connected between the EOZ unit and main exhaust duct for proper
operation.

Stainless steel rivet
NOTE! Be sure that the hose is connected to the proper nozzle on the EOZ and that the caps of the
nozzles has been removed.

Finally, secure the hose to the duct using adhesive cable tie mounts and cable ties that can found in the EOZ
packaging. .

NOTE! Be careful not to tighten the cable ties to strongly to ensure that the
airflow through the hose is not blocked.
