2. Safety precautions
The following symbols mean:
Caution! Make sure you have fully read and understood the present Manual
before using the equipment. Please pay special attention to sections
marked by this symbol.
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.
GENERAL SAFETY
The unit is designed only for decontamination.
The protection provided can be ineffective if the operation of the appliance does not
comply with the manufacturer's requirements.
Save the unit from shocks and falling.
After transportation or storage and before connecting it to the electric circuit, keep the
unit under room temperature for 2-3 hrs.
Store and transport the unit at ambient temperatures between -20°C and +60°C and
maximum relative humidity of 80%.
Before using any cleaning or decontamination methods except those recommended
by the manufacturer, check with the manufacturer that the proposed method will not
damage the equipment.
Do not make modifications in design of the unit.
The unit is not moisture resistant.
ELECTRICAL SAFETY
Connect only to the mains with voltage corresponding to that on the serial number
label.
Do not plug the unit into an ungrounded power socket, and do not use an ungrounded
extension lead.
Ensure that the power plug is easily accessible during use.
Disconnect the unit from the mains before moving.
If liquid penetrates into the unit, disconnect it from the mains and have it checked by
a repair and maintenance technician.
Do not operate the unit in premises where condensation can form. Operating condi-
tions of the unit are defined in the Specifications section.
DURING OPERATION
Do not operate the unit in environments with aggressive or explosive chemical mix-
tures. Please contact manufacturer for possible operation of the unit in specific at-
mospheres.
Do not operate the unit if it is faulty or has been installed incorrectly.
Do not use outside laboratory rooms.
BIOLOGICAL SAFETY
The user is responsible to carry out appropriate decontamination if hazardous mate-
rial spills on or penetrates into the equipment.

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.
Figure 1. Dependence of UV radiation intensity from distance to UV source (25 W lamp, 254 nm)
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. Getting started
4.1. Unpacking. Remove packing materials carefully and retain them for future shipment
or storage of the unit. Examine the unit carefully for any damage incurred during
transit. The warranty does notcover in-transit damage.Warranty covers only the units
transported in the original package.
4.2. Complete set. Package contents:
4.2.1. Standard set:
- UVR-M /UVR-Mi, UV Cleaner-Recirculator.....................................................1 pce.
- Spare dust filters..............................................................................................2 pcs.
- Spare fuse .......................................................................................................1 pce.
- Screw with dowel .............................................................................................1 pce.
- Operating manual, declaration of conformity ..................................................1 copy
4.2.2. Optional accessories:
- UVR-S support stand ................................................................................on request
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).
- Position the unit so that the access to the mains plug is unobstructed.
