Broken glass danger
The UVC tubes are made from quartz glass, and can shatter or
break. If using the UVC tubes, please wear gloves.
Guidelines if glass breaks
There is a possibility of liquid mercury leaking out from broken
or damaged tubes. If this happens, please air out the room and
dispose of shards, fragments, and tubes in appropriate waste
systems.
Danger via UVC
UVC radiation damages the cornea, eyes and skin after only a
few seconds of exposure and these areas should therefore be
protected.
Never look at a lighted UVC source without protection. Personal
protection equipment (PPE) must be worn. When controlling the
function of the UVC tubes a UVC protected pair of goggles as well
as gloves must be worn. Skin on arms is protected through
clothing with long sleeves.
Measurements on site
Cables carrying electricity should be undisturbed
The cables carrying electricity must be laid in a way that they
are not bent, cut, underneath heavy objects, or in any other
way at risk of destruction.

Warnings
The appropriate warnings (for example “Attention, UVC
radiation: Protect eyes and skin”) Must be set up in a place
where they are easy to spot before one enters the dangerous
area.
Protection against UVC radiation
Install protection against UVC radiation!
Optical glass, acrylic glass, or opaque items, like sheets are
impermeable to UVC radiation and will protect against it.
In case of emergency
Measures in case of danger to skin/eyes
With direct contact, UVC radiation leads to painful inflammation
of the eye cornea and redness of the skin.
The effect can also manifest itself after some time. In cases of
emergency, see a specialist.
This is also applicable in cases of burnt skin caused by UVC
radiation.

System description
The UVpro V-LAB Recirculating Air Disinfection System is suitable for the use in laboratories, patient rooms
and medical practices. The unit can be mounted on the wall and is able to disinfect rooms up to 60 m²
effectively. The sterilisation rate and air circulation rate can be regulated by continuously adjustable
ventilation.
The V-LAB (1) consists of a housing with operating element and display (2), side air outlets (3) with visual
protection (6) and two service covers (4).
UVC tubes (5) are mounted inside the aluminium irradiation chamber (8) and the two fans (7) are
places opposite. The powder-coated housing can be mounted in both ways, vertical and horizontal. By
means of four fixing points, the unit is attached to the rear panel (11). The centrally located operating
panel (2) can be accordingly adjusted within the unit on the retaining plate (9).

The middle plate (10) covers the operating panel from the outside. In the irradiation chamber the
UVpro tubes (5) are screwed down to the fitting carrier with a union nut on one site and fixed through
holding eyelets on the other side.
Outside, on both ends of the unit, there are visual protections with a lamellar structure (6). The
irradiation chamber is mounted in a powder-coated protective housing. Both of the service covers (4)
are fixed through socket screws on the side of the housing. With mounting holes (11) on the reverse
side of the protective housing, the unit can be attached on the wall.

3. ELECTRONIC COMPONENTS
Electronic components
The UVpro V-LAB Recirculating Air Disinfection System has a high-quality ballast (10) for optimum
operation of the UVpro tube. In this way maximum power, high frequent ignition and high durability
can be guaranteed. The high-frequency technology ensures a very high efficiency and low power
consumption. Of course, all components are in conformity with the “Low Voltage Directive” and “EMC
directive”.
If a tube has a malfunction or in case of a defect in the wiring to or in the tube socket the ballast
automatically switches the connected tube off. Thus, the circuit board will be protected and a
malfunction can be detected by our monitoring units. The temperature of the square tube with the
fully encapsulated ballast is a maximum of 35 °C (at room temperature). The optimum temperature is
between 0 °C and +40 °C. Heating to 70 °C in a short term is possible but leads to a momentary power
loss and permanently accelerates the aging of the system.
Connection directly or with UVpro monitoring unit
- Connection with the grid 230 V
AC
±10 %. The protection of the connection via a residual current
circuit breaker (30 mA) is mandatory.
- UVpro CU1 The optional monitoring unit CU1 can be used for one UVpro device. You
will find further information in the documentations of this monitoring
unit.
- UVpro UVC-Line 8/16/24 The optional monitoring unit UVC-Line 8/16/24 can be used for several
UVpro devices. Further information can be found in the documentations
of this monitoring unit.

Installation instructions
The UVpro V-LAB has been carefully inspected and passed a function test before shipping. The high-
quality packaging should prevent damage in transit. However, even with the most careful handling
damage cannot be avoided completely. The UVC-tubes made of quartz glass are most susceptible to
damage during transportation. Check the UVC tube and the tube socket prior to installation. Check if
the cables are damaged. We recommend that you check the completeness of the delivery against the
parts listed above.
The UVpro V-LAB Recirculating Air Disinfection System weighs about 13 kg. Choose a suitable wall
segment or bracket that is able to carry the additional weight.
It is necessary to note, that people and animals must be protected from UVC radiation
during installation. Also, consider possible body heights of >2 m.

Electrical connection
The electrical connection of the ventilation air disinfection unit is, under the relevant requirements
(EN 60 598-1), to be carried out by authorised personnel only.
The device may only be connected by a specialist (electrician).
The circuit must be fused with a ground fault circuit interrupter (30 mA).
Positioning and dimensioning
The correct dimensioning and positioning of the V-LAB is essential for the success of the disinfection.
It is preferably so placed that the outlet opening points towards the larger part of the room and the
distance between the wall and the outlet is not less than 1 m. We recommend to mount the V-LAB
over the doorframe if possible. Make sure that the unit is easily accessible in future (e.g. with a ladder)
and can be easily kept clean.
After proper mounting and positioning no further work is immediately necessary. Nevertheless a
regular visual inspection of the UVC tube for calcifications and other deposit should be done. Dirt and
other deposits on the quartz sleeve reduce the UVC performance significantly.
After 12,000 hours, the tubes have reached about 75 % of the output power and have to be exchanged.
(See chapter 7.2 “Replacing tubes”).

5. OPERATION AND PROGRAMMING
After plugging in the device plug, the V-LAB is in stand-by mode. Via programmable timer it can be
programmed in a daily or weekly rhythm or switched on manually.
The start menu shows the device name, the time, the
operating status and the set intensity. The depicted
example shows a unit in manual mode (Man) with a
set intensity of 100% ventilation.
The background colour of the start menu indicates
the operating status and possible errors. Please find
the colour key in the figure below.
When the tubes are cold, the set reporting threshold
for errors of the tube monitoring exceeds. Due to this,
it is possible that the display colour is purple when
switching on the unit. As soon as the tubes reach the
operating temperature, the display turns green.
