Select a location where the device is protected against extreme heat (see "7. Technical
Specifications"), dust and moisture. Respect a minimum distance of 0.5m between the device's light
output and any illuminated surface.
Use an appropriate safety cable to fix the device (e.g. VDLSC7 or VDLSC8).
Familiarise yourself with the functions of the device before actually using it. Do not allow operation by
unqualified people. Any damage that may occur will most probably be due to unprofessional use of the
device.
Use the original packaging if the device is to be transported.
All modifications of the device are forbidden for safety reasons.
Only use the device for its intended purpose. All other uses may lead to short circuits, burns,
electroshocks, lamp explosion, crash, etc. Using the device in an unauthorised way will void the
warranty.
If this device is to be used in a public place where people may access it, an armature with a protective
grille should be used (VDL60RF1 or VDL120RF1).
4. Installation
a) Lamps
Only fit or replace a lamp when the device is unplugged from the mains.
Let a lamp cool down before replacing it as the temperature of a lamp can reach 70°C during
operation.
Do not touch the tube with your bare hands. Use a cloth to insert or remove it.
Do not install lamps with a higher wattage. They generate higher temperatures than this device was
designed for.
Replace any deformed or damaged lamp with a lamp of the same type (see "7. Technical
Specifications"):
1. For VDL15UVB & VDL15UVY: remove the protective caps near the lamp connectors.
2. Gently remove the old lamp from the sockets by turning it until the lamp slides out.
3. Gently insert the new lamp into the sockets and fix it by turning it.
4. For VDL15UVB & VDL15UVY: put the protective caps near the lamp connectors back.
Remark: Do not operate the device when the cover is open.
b) Mounting the Device
Have the device installed by a qualified person, respecting EN 60598-2-4 and all other applicable
norms.
The construction to which the device is attached should be able to support 10 times the weight of the
device for one hour without deformation.
The installation must always be secured with a secondary attachment e.g. a safety cable.
Never stand directly below the device when it is being mounted, removed or serviced. Have a qualified
technician check the device once a year and once before you bring it into service.
Install the device in a location with few passers-by that is inaccessible to unauthorised persons.
Overhead mounting requires extensive experience: calculating workload limits, determining the
installation material to be used... Have the material and the device itself checked regularly. Do not
attempt to install the device yourself if you lack these qualifications as improper installation may result
in injuries.
Make sure there is no flammable material within a 50cm radius of the device.
Have a qualified electrician carry out the electric connection.
Connect the device to the mains with the power plug. Don't connect it to a dimming pack.
The installation has to be approved by an expert before the device is taken into service.
5. Use
Switch the device on and off by means of the power switch either on the device itself or on the power
cable. The UV lamp needs 3 to 4 minutes warm-up time before it reaches its maximum light output.
6. Cleaning and Maintenance
1. All screws should be tightened and free of corrosion.
2. The housing, the lenses, the mounting supports and the installation location (e.g. ceiling, suspension,
trussing) should not be deformed, modified or tampered with e.g. do not drill extra holes in mounting
supports, do not change the location of the connections ...
3. Mechanically moving parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician maintain the
device.
5. Disconnect the device from the mains prior to maintenance activities.
