Product safety instructions
Failure to comply with these instructions or incorrect use of this device may cause serious bodily injury.
The UV cleaning system is designed to treat kitchen exhaust air with UV light and ozone only as described in
this manual.
Use of this UV technology reduces odors and reduces fat, mold and bacteria to water vapor and dry minerals.
ETS NORD AS assumes no liability if the product is not used in accordance with the manufacturer’s instructions
in this guide.
The installation of the Control Unit may only be carried out by persons trained and authorized by ETS NORD in
accordance with international standards and regulations.
It is forbidden to use replacement lamps or any other spare parts that are not supplied by ETS NORD Customer
Service.
Ultraviolet radiation and ozone are harmful to health. Prolonged exposure can cause the following damage:
• Skin rashes and burns
• Eye irritation, retinal burn and loss of vision
• Respiratory irritation and breathing problems
When removing grease filters from a UV-canopy, ensure that the UV system is powered o at the main
electrical closet or safety breaker.
When installing servicing or servicing the lamps, always wear goggles and protective gloves to protect against
quartz fragments in case of UV-C lamp breakage.
Check your product

1.3 Installation of pressure measurement hoses
Next, two pressure measurement hoses shall be connected between the nipples protruding from the Control Unit
to their respective nipples on the ceiling of the supply chamber. Connect the rightmost hose to the rightmost
nipple (picture 1). This hose provides the system with the static pressure of the surrounding environment. Attach
the left hose to the left pressure nipple (picture 2). Ensure that these connections are made correctly and that
the hoses are firmly attached to each nipple.
Next, the long exhaust pressure measurement hose must be connected above the canopy. Connect the hose
from the nipple closest to the center of the canopy to the nipple above the exhaust chamber. Ensure that the
hose is firmly attached to each nipple.
NOTE! To prevent dirt or debris from entering the Control Unit or pressure measurement hoses, cap
them o until installation is ready to be performed.

6. Maintenance
In the case of a soiled but functioning lamp, cleaning is required. In the case of a defective lamp, it must be
replaced. Only replacement parts supplied by ETS NORD Customer Service may be used when servicing ETS
NORD equipment. The defective lamp shall be delivered to the appropriate waste treatment site.
6.1 UV shield and grease filter removal
Power o the UV system and verify the device is o at the Control Panel before removing UV shield and grease
filters. Use UV-protective glasses as a safety precaution. After the system and lamp have been powered o,
wait 3 minutes until the lamp has cooled for safe handling.
Remove the shield, and then the grease filters.
NOTE! After 10,000 working hours, the intensity of the lamps decreases by 20% at 185nm. It is
recommended to replace all UV-C lamps in the system after this time.
NB! Before UV-C lamps are serviced, make sure that the system is turned o and, after
switching o, wait 3 minutes until the lamps have cooled down for safe handling.
NB! Use safety goggles and gloves during maintenance!
NB! Risk of falling! Make sure that the device is installed with adequate support.

6.2 UV-C lamp electrical disconnection
Disconnect the lamp from the power circuit by first twisting the locking rings counterclockwise, then pulling the
connectors downward. Never pull on the cables themselves, only the connectors.
6.3 UV-C lamp removal from exhaust chamber
Release the lamp from the clamp attachments by unscrewing the screw.
2x
To install a new UV-C lamp, see chapter 2 “Installation of UV-C lamps”. After installing new lamp start the
system and ensure that it functions properly by observing the Control Panel.
NB! In the case of a running device, UV shields and filters must never be
removed due to the risk of ultraviolet radiation!
NB! Lamps should only be handled with protective gloves and eyewear.
