1. Check the product shipment
Check that the parcel contains all components listed below and that there is no visible damage.
Notify both the freight forwarder and supplier immediately of any damage or missing components.
Before installing the device read through the entire instruction material.
The Ozone Cleaning System consists of two key components:
- One or more Ozone Modules
- Control Panel
Each OZ 3.0 package contains:
- OZ 3.0 Ozone Module
- Short pressure measurement hose
(60cm)
- Long pressure measurement hose (3.5m)
- Power cable with IEC C13 plug (3m)
The Control Panel package contains:
- Control Panel
- One sheet of Ozone Module device address identification labels
There is typically one Control Panel for each kitchen. The number of Ozone Modules is dependent on the design
of the kitchen and the canopy as well as the equipment used for cooking. This is decided when planning the
kitchen.
2. System overview
The Ozone Modules produces ozone gas. Ozone (O
3
) 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

3. Prepare the Ozone Modules
3.1 Set the device addresses
Each OZ module must be set to a unique device address
A flashlight and a long, narrow 2mm flat-head screwdriver will be
needed for this procedure. The unit will not need to be opened as the
necessary rotary switches can be accessed through the air intake at
the bottom of the chassis as shown in the picture.
NOTE! Before installing any Ozone Module, please ensure that
its air intake adjustment plate, if installed, is adjusted for full
airflow through the perforated holes and the fixing screw is
tightened.
Set the device address for each Ozone Module by turning the
rotary address switches located on the upper left corner of the
air intake grid. The address is set using the switches marked
“1x” and “10x”. The “1x” switch is positioned nearest the corner
of the circuit board.
Example:
Ozone Module one (Adress 1):
Switch 1x = 1
Switch 10x = 0
Ozone Module thirteen (Adress 13):
Switch 1x = 3
Switch 10x = 1
Addresses should be set in ascending order begin with the Ozone Module closest to the Control Panel and
increasing by one for each sequential module. The first connected Ozone Module should have the address 1.
Mark the installation positions of each Ozone Module
The location of each Ozone Module shall be marked by placing an identification label on the upper front panel
of the canopy. The label should match the device address of
the module installed beneath it. You will find a sheet of labels
in the Control Panel package.

4. Installation
4.1 General information
Ozone is drawn into the grease chamber through the ozone duct, which is located on the ceiling of the canopy.
The ducting and bends necessary for connection are included with the canopy.
Always install the ozone ducting according to the manufacturer’s drawings.
The ozone duct must be made of acid-resistant stainless steel (AISI 316).
Before starting the Ozone Module, check visually that all ozone duct connections are airtight.
Always leave a minimum of 500mm free space in front of a canopy to allow access for maintenance.
Never drill or screw into the Ozone Module chassis.
If the kitchen has already been operational before installation of any Ozone Modules, the exhaust ducts should
be thoroughly cleaned from grease and soot to achieve the best results.

4.2 Connect the pressure measurement hoses
For an Ozone Module to operate properly its two pressure measurement hoses must be connected.
- Two hoses, one long and one short, are provided in the shipping carton. Feed the long hose through the
Ø100mm ozone duct into the exhaust chamber.
- While lifting the module into place, securely attach one end of the hose to the hose located in the Ozone
Module 100mm flange. Raise the module into place, gently pulling the hose from its other end to ensure it
does not become kinked or disconnected in the process.
- Secure the 4 fixing clamps to fasten the module to the inside roof of the canopy. Clip o the excess hose
as shown in the diagram.
Note the location of the pressure nipple near the module mounting bracket inside the canopy. Securely attach
the shorter hose between the nipples on the module and the canopy.
NOTE! There are two hoses that need to be connected to each module.

5. Electrical Installation
The ozone generator system must be interlocked with the exhaust system, so that when the exhaust ventilation
is not running, no electrical power is supplied to the ozone system. See the sample diagram below as one
possible option to accomplish this function.
A maximum of 4 Ozone Modules and one alarm panel may be connected a single 10A C-type (slow) circuit
breaker.
NOTE! Electrical installation must be performed by an authorized electrician and follow local, regional
and national standards and regulations.

5.1 Connect the main electrical supply
Each ozone generator has its own power supply connection:
- A maximum of 4 ozone generators and one alarm panel may be connected a single 10A low-speed circuit
breaker.
- Please label the circuit breaker number used on each generator as would normally be done for external
appliances.
Control Panel power cables may be fed through either the rear wall or the cable bushings in the bottom of the
case. Connect the 230V supply cable to the power supply terminals L, N and PE, as shown in the diagram.
Each Ozone Module has its own power cable that can be found inside the packaging. Connect it to the Ozone
Module as seen in the picture below.

5.2 Control Panel and the Ozone Modules data wiring
Three cables are 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.
Ozone Modules are connected sequentially (”daisy-chained”) from the Control Panel to the nearest Ozone
Module, then to the next module and so on. However, please note that although the physical cabling is
”chained” from one device to the next, the data cables are connected together in a parallel format. That is,
similar terminals between devices are connected together; there are no specific ”in” or ”out” data terminals
on the various components.
Maximum limit for the number of Ozone Module connected to the Control Panel is 99 and maximum length of
the data cable is 500m. However, it may be advantageous to have multiple Control Panels in larger facilities.
Cable bushings come preattached inside the supply chambers.
*3x0,25 mm2 or another shielded data cable with at least 3 conductors.
Data terminal A-, B+ and C (GND) are connected similarly between the Control Panel and each Ozone Module.
Note the cable colors used on each terminal to ensure all devices are connected similarly.
As stated above, the data cables are typically run through the facility in a daisy-chained format, although the
individual communications wires themselves are connected in parallel. In this way data communications
between devices will remain active even in the case one of them is powered o, malfunctioning, or unplugged
and removed.
Thus, each A-, B+ and C data wire leading
in from devices on both sides of any Ozone
Module in the chain should share the same
terminal screw in its respective connector. In
this way the three extra unused terminals just
below on the connector block can be reserved
for future expansion.

Finally, if it is desired to connect the system to the local area network, connect the LAN cable to the Control
Panel by unplugging the existing short LAN jumper cable inside and connect your LAN cable straight to the
port on the board as seen below.
LAN cable must be connected to a network switch or to the closest LAN socket.
Reassemble the housing in reverse order, with the smaller LED display above the larger one. Ensure the text
on the plexiglass is oriented correctly and fasten the housing with the two fixing screws on the sides.
Please note! After powerup, starting up the Control Panel takes approximately 40 seconds. The
system operating interface is unavailable until this boot process has completed.

Facts about ozone
• Ozone is a colorless gas, the sharp smell of which can be detected by a person at a concentration of 0.02
ppm (0,4 mg/m3).
• The smell of ozone is similar to the smell of chlorine used in swimming pools.
• The use of ozone is subject to the applicable protection legislation. For example, in Sweden, the Swedish
Work Environment Authority provides the following hygienic limits for ozone:
- 0,05 ... 0,2 ppm (during working time, 8 hours)
- (Directive 2000/39/EC) 0.3 ppm (15 minutes)
• Acute exposure to ozone may result in the following damage:
- skin irritation and burning sensation
- severe irritation and burns in eyes and vision loss
- pulmonary irritation in the respiratory tract and respiratory problems
• If the presence of ozone is detected indoors, the Ozone Module must be switched o immediately and
the area must be ventilated.
