3. General information
UV DNA/RNA cleaner-recirculators UVR-M & UVR-Mi are compact airflow exchange
chambers with built-in UV lamp and a fan unit equipped with dust filters and a control unit.
UV DNA/RNA recirculators provide active constant airflow in close vicinity to UV lamp, en-
suring maximum efficiency of disinfection, as shown in figure 1. Low ozone 25 W G13 lamps
with 9000-hour lifetime are used, one in the UVR-M model and two in the UVR-Mi model.
The UVR-Mi model provides the scheduling option for switching on and off and the
estimation of lamp overall operating time and condition.

UV radiation affects viability of microorganisms by causing photochemical reactions
in the structure of DNA and RNA. Adjacent pyrimidine molecules form dimers and block the
reproduction of microorganisms, as a result, causing their death. The diagram on figure 2
shows the process of formation of pyrimidine dimers, using thymine as an example.

4.3 Setup.
- Choose recirculator location so that the air intake and discharge operate unim-
peded, providing the best air circulation in the room.
Caution!
UV recirculator must be used only in clean rooms! Dust accumulation on
the electrical parts of the device can cause a short circuit.
- Fix the unit on the wall with the screw and dowel, or on a UVR-S movable support
stand (figure 3).

5. Operation
Caution!
Bactericidal lamp properties reduce by ~12% after 5000 hours of opera-
tion (data given by the manufacturer), so lamp replacement or air recircu-
lation time extension by 12% is recommended in order to achieve the de-
sired air cleaning result.

5.2.7 End of lamp lifetime and lamp failure. At the end of lamp lifetime (9000 h) or in
case of UV lamp failure, unit terminates operation and does not resume until lamps
are replaced. Display shows “END OF UV LAMP LIFETIME” or “ERROR UV LAMP
FAILURE” messages, respectively. Additionally, check the indicator (fig. 5/8) to see
if the lamps are working. To replace the lamps, see 8.3.
5.2.8 After finishing the operation, switch off the power switch and unplug the power cable
from the mains.

8. Care and maintenance
8.1 Service.
8.1.1 If the unit is disabled (e.g., lamp or fans not working, no reaction to key presses, etc)
or requires maintenance, disconnect the unit from the mains and contact Biosan or
your local Biosan representative.
8.1.2 All maintenance and repair operations (except listed below) must be performed only
by qualified and specially trained personnel.
8.1.3 Operating integrity check. If the unit follow the procedure described in section 5. Op-
eration, then no additional checks are required.
8.2 Cleaning and disinfection.
8.2.1 Use mild soap and water with a soft cloth or sponge for cleaning the exterior. Rinse
remaining washing solution with distilled water. Wipe dry the excess water with clean,
soft cloth or sponge.
8.2.2 Dust filter control/replacement. The dust filters on either end of the UV-recirculator
should be checked monthly and cleaned or replaced when they become clogged. To
check, replace or clean the filters, simply unclip the covers (fig. 4/and 5/), if nec-
essary, fit a new one; otherwise rinse in water, dry, and set up existing filters. Clip
covers back in place.
8.2.3 To disinfect the exterior plastic parts, use 75% ethanol or DNA/RNA removing solution
(e.g., Biosan PDS-250).After disinfecting it is necessary to wipe the surfaces dry.
8.2.4 Cleaning of the interior. Cleaning of the interior must be performed only by qualified
and specially trained personnel. In order to ensure proper efficiency in the long run,
it is recommended to clean the UV-recirculator once a month.
8.2.5 The unit and its accessories are not autoclavable.

8.3 UV-lamp replacement. Replacement must be performed only by qualified and spe-
cially trained personnel. UV lamp replacement is necessary after lamp stops func-
tioning or at the end of manufacturer specified lifetime. Use the indicator in the centre
of recirculator (fig. 4/2 or 5/8) to check UV lamps inside the recirculator. If the indicator
is alight while the switch is ON, then the UV lamps are functioning. If it is not, replace
the lamp, single lamp in case of UVR-M, both - in case of UVR-Mi.
Caution!
Do not switch on the unit with the cover removed or without filters! UV
lamp must be covered at all times during operation. Otherwise, UV lamp
can expose the operator and other people to dangerous levels of UV light.
8.4 Fuse replacement. Disconnect the unit from the mains and unscrew the fuse holder
cap (fig. 4/3 or 5/10). Check the fuse and replace, if necessary, with a correct one:
