Purified Air UV-O 1000 Operating instructions

UV-O 1000
TECHNICAL & OPERATION MANUAL

This product contains lamps that produce UV
light. Immediate or prolonged exposure to UV
light can result in painful eye injury, skin burn,
premature skin aging, or skin cancer.
This product creates OZONE (O3). Inhalation of
ozone causes dryness of the mouth, coughing,
and irritates the nose, throat, and chest. It may
cause difficulty in breathing, headaches and
fatigue, and could aggravate existing bronchial
conditions including asthma. The characteristic
sharp, irritating odor is readily detectable at low
concentrations (0.01 to 0.05 ppm).

Use of UV-O 1000
The product is suitable for the filtration of extracted fumes from commercial kitchens.
The product should always be used in combination with prefilters that are suitable for kitchen
extract.
Service, maintenance and repairs
The maintenance of the UV-O 1000 unit is a very specialist task and should not be carried
out by anyone who has not received specialist training by Purified Air Limited
Observe the maintenance intervals given in this manual. Overdue maintenance can lead to high
costs for repairs and revisions and can render the guarantee null and void. Always use tools,
parts and service techniques that have been approved by the manufacturer. Do not carry out any
service, maintenance or repairs on the product before it has been protected against unintended
starting. Clean and replace the lamps in accordance with the times indicated in section 6
Maintenance of this manual. Appropriate PPE equipment should be worn at anytime when
there is a possibility that the light emitted from the UV lamps can be viewed or come into
contact with skin. If ozone can be smelt in the area where the UV-O 1000 unit is installed,
it has been incorrectly installed and should be isolated. Contact Purified Air for further
information.

4 GENERAL DESCRIPTION
This UV-O 1000 can remove, at high efficiency, odorous compounds. The UV-O 1000 is
designed to be installed in the extraction ducting of a commercial kitchen down stream of the
extraction hood and upstream of the fan.

It is recommended that the unit is commissioned by Purified Air Ltd to ensure that the unit is
installed correctly and safely. The following are very important safety points that must be
adhered.
The unit must be installed on the suction side of the fan
The operation of the UV-O 1000 must be linked to the operation of the extract
system. This is achieved by connecting the Air Flow Proving Switch as follows:
Fix the negative pressure probe only (using a 2mm drill and 7mm drill) to the BRANCH DUCT
which connects the UV-O 1000 to the main extract duct, connecting this via the PVC tube to port
P1 and leave unused port P2 open to atmosphere (see Fig.3 & Fig.4). Also link the power supply
between the extract fan and the UV-O 1000.
To give a signal of fan running, wire onto terminals 1 and 3. Set the dial at about 30Pa. DO NOT
set below 20Pa.

The UV-O 1000 will produce ozone which is a poisonous gas with a distinctive
smell. The kitchen extract system into which the UV-O 1000 system is installed
must be sound with no holes that will allow ozone to escape. If ozone is smelt
within the premises the UV-O must be switched off immediately.
Care must be taken that the kitchen extract point is not close to air inlets, windows
etc. where elevated ozone levels will cause a problem.
Rigid ducting should be used to connect the UV-O 1000 unit.
The following points should also be considered.
The UV-O 1000 unit should be located in close proximity to the kitchen extract ducting.
The unit should be positioned with good access to allow for future servicing and maintenance.
If the unit is to be mounted onto a wall the casing can be drilled to allow this. When drilling the
case it is important to make sure that the fixing used will not allow any UV light to escape.
Alternatively brackets are supplied, that can be fixed to the spigot and inlet plates via the bolts
already in place, as shown in Fig.5.
BRACKETS BRACKETS
Fig.5
150mm diameter galvanised metal ducting should be used to connect the
UV-O 1000 unit to the kitchen extract duct (see Fig.2). The ducting should connect securely to
the spigot on the front of the unit and should spigot into the kitchen extract duct.
It must be proved that when the kitchen extract fan is running air passes through the air inlet of
the UV-O 1000 and into the kitchen extract duct. Under no circumstances should the unit be
used if airflow is the opposite direction. The vent on the air inlet hood can be used to regulate
the airflow through the system. The air flow needs to be at least sufficient to activate the airflow
sensor.

Once the UV-O 1000 has been mounted and the ducting connected the special UV lamps should
be inserted. Access is via the front panel which hinges open once the lock and star knobs have
been released. The lamp holder can be pulled clear of the unit on a runner system to make
installation of the lamps easier. The lamps clip into position and connect with the plugs supplied.
Once the lamps have been fitted the front cover can be replaced.
Fig.6

The UV-O 1000 should now be wired into the mains via the isolator on the front of the unit.
Fig.7
Once unit is wired and necessary safety requirements have been adhered to the UVO-1000 can
be switched on. The safety switch light indicates that the various safety switches, the airflow and
micro switch are engaged and that airflow is present. The power light indicates that power is
present.
Note:
To check that all UV lamps are working it is necessary to attach bypass switches, (supplied) to
the micro switches on the inside top front of the UV-O 1000 (see Fig.6) to enable the front panel
to be open when the unit is in operation.
Appropriate PPE equipment should be worn during this check.

6 MAINTENANCE
The maintenance of the UVO-1000 unit is a very specialist task and should not be carried
out by anyone who has not received specialist training by Purified Air Limited
If you carry out the simple maintenance and cleaning described below at the regular intervals,
then any problems will mostly be detected and corrected before they result in a total breakdown
of the product.

Cleaning the UV lamps
UV lamps should be cleaned using alcohol wipes and a lint free cloth. Care should be taken not
to handle the lamps with bare hands as this will damage the glass of the lamp.
It is a matter of experience to determine when the product needs to be cleaned, since the nature
and the degree of pollution depend strongly on the particular situation, humidity, intensity of use,
etc. Nevertheless the UV lamps should be cleaned regularly.
Appropriate PPE equipment should be worn at anytime when there is a possibility that the
light emitted from the UV lamps can be viewed or come into contact with skin.
