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").
