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 3.1 package contains:
- OZ 3.1 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 (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.

3. Prepare the Ozone Modules
3.1 Set the device addresses
Each Ozone Module must be set to a unique device address.
Start by removing the bottom cover by unscrewing the four (4)
M5x12 bolts from the side panel with T4 screwdriver and keep
them in a secure place for later use.
To assign unique addresses to Ozone Module a narrow 2mm
flat screwdriver will be needed. All Ozone Modules connected
to a single Control Panel must have a unique device address.
Addresses need to be set in ascending order begin with 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.
Example:
Ozone Module one (Adress 1):
Switch 1x = 1
Switch 10x = 0
Ozone Module thirteen (Adress 13):
Switch 1x = 3
Switch 10x = 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.
NOTE! Installation may only be carried out byby specialist and authorized persons in accordance with
local, regional, national standards and regulations.

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.
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.
Width of service area
min 500 mm
Never drill or screw into the Ozone Module chassis.

4.2 Connect the pressure measurement hoses
For an Ozone Module to operate properly its two pressure measurement hoses must be connected.
NOTE! There are two hoses that need to be connected to each module.
- 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.
- 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.

5. Electrical Installation
NOTE! Electrical installation must be performed by an authorized electrician and follow local, regional
and national standards and regulations.
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. Remember to label the circuit breakers used in the distribution board

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.
If applicable, install the I/O data cable for your building automation system or for future upgrades.
Connect the five (5) terminals DI1, DI2, DO1, DO2 and COM+ and mark the other ends of the wires within the
junction box with their corresponding terminal assignments.

Rout the other end to a junction box that is situated on top to the canopy.
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.

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.
