Operation and Maintenance Manual
2 OPERATION
2.1 Principles of Operation
The UVM9 air purifier is a self contained air purifier that requires period maintenance as set
out within this manual.
Operation is either manually via the Mode Switch on the top of the purifier which selects
either constant on or Intelligent operation via a programmed function that starts the purifier
when the room is occupied and the fans rin for a set time.
Air is drawn through the bottom of the unit with the built in fans and passes through the UV
lamp and catalytic filter before being expelled back into the room through the disposable
particulate filter.
In Photocatalytic air purifiers the catalyst that cleans the air is topically titanium dioxide and
is energised by the ultraviolet light.
When UV light shines on the titanium dioxide, electrons are released at its surface. The
electrons interact with water molecules (H2O) in the air, breaking them up into hydroxyl
radicals (OH·), which are highly reactive, short-lived, uncharged forms of hydroxide ions
(OH−).
These small, agile hydroxyl radicals then attack bigger organic (carbon-based) pollutant
molecules, breaking apart their chemical bonds and turning them into harmless substances
such as carbon dioxide and water.

3 SAFETY INSTRUCTIONS
It is a requirement of the relevant Health & Safety at Work regulations that employers
provide such information, instruction, training and supervision as is necessary to ensure, so
far as is reasonably practical, the Health, Safety and Welfare of their employees.
3.1 General Health and Safety
This PureAirTM UVM9 purifier has few exceptional Health and Safety Risks associated with it.
Listed below are some of those that should be considered in the installation, operation and
maintenance of the equipment.
Maintenance
Maintenance of this unit must be treated with care. General maintenance of individual
items must be carried out within the DSEAR risk assessment and should not be carried out
with the unit in operation.
Electrical
The unit is connected to a 220VAC 50/50Hz single phase mains power supply rated at 1.2A.
Chemical
The UV lamp contains 10 – 15mg of mercury. Under normal operating conditions there is no
personal exposure to mercury. Changing a failed lamp will not cause any personal exposure
to mercury. Mercury will only be liberated from a broken lamp. Mercury liberated from a
broken lamp will be in both vapour and liquid form. In the event of a broken lamp, it is not
foreseen that, given satisfactory precautions for collection and disposal of broken quartz,
any personal exposure to mercury will be experienced.
For handling broken quartz, protective gloves, eye protection and other appropriate PPE
should be worn.

4 INSTALLATION
4.1 General Description of system
The UVM9 air purifier comprises a wall mounted purifier complete with a 24V power supply
that needs to be connected to a 110v/220v 1 phase 50/50Hz supply. The basic parts of the
purifier are a replaceable filter, 4 small fans that draw the air through the purifier, a UV lamp
and catalytic filter.
The purifier has the following approximate dimensions: 12 x 6 x 2.5 inches (300mm x 150mm
x 66mm) and weighs 3.3lbs (1.5Kg).
Airflow through the unit is inlet at the bottom and outlet at the top. Fig 1.
The UV unit includes all necessary controls. Connections to the power lead, UV sensor and
temperature controller are all hard wired into the control panel.
Installation of the purifier is recommended 6 Inches (150mm) down from the ceiling.
Mounting of the power supply can be either in the room or ideally above the roof space (in
an elevator).
To mount the unit remove the backing stripes from the 4 adhesive pads on the rear of the
purifier. Fig 2. Ensuring the unit is level gently push the purifier onto the wall applying even
pressure along the purifier, the adhesive strips will then keep it in position. Using the self
tapping screw (supplied) screw through the hole in the hanger into the wall to give
additional support to the purifier.

Note the requirements for the incoming electrical supply is 110/220V, 50/60Hz, 1 Phase and
must be fitted with a disconnect/fuse rated at 1.2 Amp.
Locate a local disconnect near the purifier unit so that electric power may be conveniently
turned off for servicing.
4.3 Mounting and Placement
Install the UV unit in a suitable area to be treated and at accessible for periodic maintenance
purposes. Ambient temperatures surrounding the unit should be between -20°C and +45°C.

5 MAINTENANCE
5.1 Routine Maintenance
The UVM9 air purifier is designed for the minimum of maintenance. However, regular
inspection and preventative maintenance of the plant and equipment, together with a
systematic method of recording plant operation, are essential for the long-term reliability of
the equipment.
Daily:
Check operation of purifier. Note a slight blue colour can be seen through the filter to
indicate the UV lamp is working.
3 Monthly:
Change the air filter (see instructions below)
Annually:
Change the Catalyst and UV lamp (See instructions below)
5.2 Air filter replacement
The air filter fitted to the purifier should be replaced every 3 months with a replacement
bought from MicroTek or its approved stockist.
To replace the filter simply slide the housing out from the top of the purifier as shown in Fig
1 below, remove the filter from the holder Fig 2. Insert the new filter into the housing and
