Operating the UV/Air Circulator
The UV/Air Circulator is built into the PCR
systems. To operate the circulator, press the
UV/Air Circulator switch to the ON position. The
circulator will pull air from inside the chamber
through the circulator, decontaminating the air
with shortwave UV and blowing the air back into
the chamber.
NOTE: Do not place equipment in front of the air
vents to block air flow.
Operating the Overhead UV and Fluorescent White Light
UV Keylock
The HEPA/UV3 PCR System provides an automated process for eliminating contamination by utilizing
the germicidal properties of shortwave 254nm ultraviolet light. The UV light is typically operated when
no samples are inside the chamber. The chamber is decontaminated, eliminating viable fungi, bacteria,
and yeast.
An optional UV/Air Circulator module can be mounted into the workstation chamber for elimination of
amplicons of DNA or genomic DNA from a previously dispensed experiment. Power switch, outlet, and
mounting brackets are pre-installed at the factory if users purchase a module at a later time.
To use the UV decontamination function, turn the UV keylock ON, and then press the timer to operate
the germicidal lamp housed within the chamber. The UV timer allows selection of UV exposure time.
The timer may take a few seconds to initialize once the timer has power. The timer will only operate
when the door is shut and the magnetic safety switch on the door is engaged. When door is open the
timer will not operate.
The default timer setting is 30 minutes, adjustable at 5 minute increments from 5 to 60 minutes, then at
15 minute increments up to 12 hours. To adjust the timer settings:
1. Turn the system on and wait until the timer reads “OFF”.
2. Use a small paper clip to press the Timer calibration button located in the small hole to the
left of the timer for one second.
3. Press the main timer button to adjust the timer settings. Each press will increase the amount of
time by 5 minutes (eg 35:00, 40:00, etc.) until one hour is reached. After one hour is reached,
the time will be adjusted in 15-minute increments and will read without a colon. For example,
one hour will read “1 00,” one hour and 15 minutes will read “1 15” and so forth.
