Introduction

The UV/Air Circulator Module is designed to mount into the UV PCR Workstation to eliminate
reduce contamination within the workstation during experiment processing without exposing
samples. Connections for mounting and powering the module are built into the workstation.
Features of the UV/Air Circulator:

 Easy to install, lightweight design
 High intensity 15 watt shortwave UV
 Recirculating decontaminating airflow
 Antimicrobial coated stainless steel to reduce bacterial growth
 Access port for measuring the UV intensity with a UV sensor
 Easy access for UV tube replacement

Safety Information

Caution: The unit includes shortwave UV, which is a powerful source of UV radiation that will
cause damage to unprotected eyes and skin. Before operation, ensure person nel in the area are
protected and that instructions for use of this equipment are followed.

Installing the UV/Air Circulator Module

Carefully remove the unit from the packaging
materials. Turn off and unplug the PCR
workstation from the wall power supply prior
to installing the UV/Air Circulator.

Locate the two mounting brackets on the
PCR workstation. Open the door of the PCR
workstation to a fully open position.

Lift the module into the workstation and set it
onto the brackets.

Secure the module to the workstation with
the thumbscrews.

Connect the jumper power cable from the
circulator to the PCR Workstation.

Reconnect the main power source.

Operating the UV/Air Circulator

The UV PCR Workstation provides a process for reducing contaminati on by utilizing the germic idal
properties of shortwave 254nm ultraviolet light. An UV/Air Circulator module can be mounted into
the workstation chamber for continual reduction of contamination during experiment processing.
Power switch, outlet, and mounting brackets are pre-installed at the factory.

To use the UV/Air Circulator, push the UV/Air power switch on the
panel shown above and the circulator module to th e ON position.
The UV/air is safely decontaminated and recirculated within the
chamber.

Warning: Exposure to UV light is harmful.
The PCR workstation acrylic door is UV blocking and will not allow
UV radiation to pass through the door. The germicidal lamp will
shut off if the acrylic door is opened. The PCR Workstation
contains a powerful source of UV radiation that will cause damag e
to unprotected eyes and skin. Before operating any u nit, be sure
all personnel in the area are properly protected.

Maintenance, Parts/Accessories

Care and Cleaning

The stainless steel surface of the PCR Workstation and the UV/Air Circulator is manufactured with
an antimicrobial coating to reduce bacterial gro wth. Care in cleaning and use of the equipment is
recommended to reduce wear of the coating.

 Warning: Unplug the unit before cleaning of in case of accidental fluid spillage
 Wipe excess water from the unit with an absorbent soft cloth or sponge.
 Use a mild detergent on the interior surfaces.
 Do not use abrasive pads or cleansers.

Measuring the UV Tube Intensity

As the ultraviolet tubes age, the intensity and germicidal destruction rate decreases. It is important
to monitor the efficiency of the tubes with a UV intensity meter to ensure the germicidal
requirements are met. The germicidal destruction rate is a function of the UV intensity at
wavelength 254nm and exposure time. The lower the tube intensity, the longer the lamps must be
on to accomplish the same objective. The UV meter using a 254nm sensor will allow the user to
measure the 254nm emissions from the tubes.

Power switch for the

UV/Air Circulato

When it is time to measure the UV intensity of the
UV/Air Circulator (recommended weekly or more
often if used frequently), the sensors can be
positioned in front of the sensor access port
located in the center of the module.

Remove the sensor access port by unscrewing
the two thumb screws.

CAUTION: UV/Air Circulator must be unplugged or the power switch turned in the off position to
avoid UV exposure during removal of the access door. Protective eye/facewear and prote c tive
gloves must be worn to avoid exposure to the 254nm UV!

Turn the UV/Air Circulator ON after removing the
access port.

Position the UV sensor over the sensor access
(UVX Radiometer and Sensor shown).

Wait 3 minutes to record the measurement on the
UV meter. It is recommended that the user record
an initial value upon receipt and assembly of the
PCR unit.

After the measurement is taken, reposition the
sensor access door with the thumb screws.

Replacing the UV Germicidal Tube

Turn the power off and unplug the unit from the
outlet.

To change the UV tube in the UV/Air Circulator,
unscrew the four thumb screws from the tube
access door. The tube has two prongs on each end
that fit into a socket. Carefully hold the tube on the
end and insert the tube into the socket. Twist the
tube 90° until the tube locks into place.

Replace the tube access door.
