1.5 Safety Warnings and Cautions
WARNING! RISK OF EXPLOSION!
These Units are not explosion-proof rated. They can cause sparks and
should therefore not be used in areas with an explosion risk.
WARNING!
Ozone (O3) is produced by these Units. Ozone can be poisonous at
certain levels of concentration.
Inhalation of ozone causes dryness of the mouth, coughing, and
irritates the nose, throat, and chest.
Itmaycausedi󰀩cultyinbreathing,headachesandfatigue,and
could aggravate existing bronchial conditions including asthma.
The characteristic sharp, irritating odour is readily detectable at low
concentrations (0.01 to 0.05 ppm).
UNIT MUST NOT BE OPERATED WITHOUT KITCHEN EXTRACT FAN
RUNNING.
WARNING! - DANGER OF ELECTRIC SHOCK!
●To avoid electric shock:
●Do not operate these Units without a proper electrical ground/earth.
●Always disconnect power to these Units and isolate them from the
power supply before performing any service or maintenance.
●Do not operate these Units if their power cables are damaged, or if
any other damage to them is visible or suspected.
●The supplied utility/mains power must match the power
requirements listed on the Units’ rating labels.
WARNING!
●These Units contain lamps that produce UV light.
●Avoidexposuretodirectorreectedultravioletrays.
●Immediate or prolonged exposure to UV light can result in painful
eye injury, skin burn, premature skin aging, or skin cancer.

2.1 Intended Use
UV-O Odour Control Units are designed to efficiently remove odorous compounds from the
fumes extracted from commercial kitchens.
Simple to install, the Units are designed to be located on the outside of the ducting. The fact
that they are externally located makes these Units ideal for retrospective installations and,
as the UV lamps are outside of the airstream, maintenance requirements are minimal.

UV-O Odour Control Units

To maximise the Units’ e󰀩ciency, they should be installed into the extraction ducting of a
commercial kitchen, down stream of the extraction hood on the negetive side of the fan.
CAUTION
Using these Units for other purposes is considered contrary to their
intended use. The manufacturer accepts no liability for any damage
or injury resulting from such use.
These Units have been built in accordance with state-of-the-art standards and recognised
safety regulations.
CAUTION
Only use these Units
●If they are not damaged in any way.
●After following the instructions laid down in this manual.
2.2 Features
When installed correctly, Puried Air’s UV-O Odour Control Units have the following
features and benets:
● Use highly efficient UV-C technology.
●Robust, compact construction.
● Twelve month effective lamp life.
●Minimum maintenance requirements.
●Enhanced safety - UV-C lamps are locked behind panels.
●Optional self-diagnostic system.
●Designed to complement our Electrostatic Precipitator (ESP) system.
●Reduce the need for duct cleaning.
●Can reduce cooking odours by up to 90%*.
●Grease is broken down in to more easily managed compounds.
●Virtually no pressure increase within the duct.
* In particularly odourous environments, high levels of odour control will only be
achieved by also using good quality particulate control systems (particularly ESPs) and
supplementary odour control systems in conjunction with this Unit.
2.3 Operating Principles
Puried Air’s UV-O Odour Control Units contain either two (UV-O 500) or ten (UV-O 1000)
high output UV-C (short-wavelength ultraviolet radiation) lamps and are designed to be
located outside the extraction duct.
2.3.1 Ozone and Free Radical Production
The UV light produced by the UV-C lamps converts oxygen present in the air into ozone.
Technical and Operations Manual - Product Overview

Technical and Operations Manual - Product Overview 9
UV-O Odour Control Units
Ozone is a highly reactive oxidant which interacts with most contaminants, allergens and
odour producing compounds it comes into contact with, oxidising them and rendering
them harmless.
The UV light produced by the lamps can also further convert the ozone to hydroxyl free
radicals in the presence of water or water vapour.
Free radicals are highly reactive oxidants which makes them e󰀨ective natural air cleansing
agents.
The mixture of ozone and hydroxyl free radicals produced in this way creates a much
more powerful oxidising action (Ozonolysis) than the use of ozone alone.
2.3.2 Location
It is widely accepted that the best way to apply UV-C is in the airstream itself. However, in
such a situation, the lamps can quickly become dirty, greatly reducing their e󰀨ectiveness.
Unlike other UV-C systems, the UV-O Odour Control Units are designed to be located
outside of the kitchen extract duct, connected via a spigot.
Negative pressure forms as the extract fume is drawn down the duct across the spigots
opening, thus drawing ambient air into the Unit and across the UV lamps producing Ozone
which is then introduced into the duct.
As the ambient air is relatively contaminant free the lamps stay cleaner allowing a more
constant production of Ozone.
2.4 Components
2.4.1 UV-O 500 Components
The UV-O 500 Unit consists of a Main Chassis which contains the UV lighting source
behind a lockable, hinged, access panel.
