3. General Guidelines
• This device is designed for professional use on stage, in discos, theatres, etc. The VDP250MH14 should only be
used indoors with an alternating current of max. 230V AC/50Hz.
• Lighting effects are not designed for permanent operation: regular operation breaks will prolong their lives.
• Do not shake the device. Avoid brute force when installing or operating the device.
• Select a location where the device is protected against extreme heat (see "8. Technical Specifications", p.8), 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. 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.
4. Installation
a) Lamp
• 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 700°C during operation.
Also, do not switch the lamp back on within 10 minutes after having turned it off.
• When handling a halogen lamp, do not touch it with your bare hands. Use a cloth to insert or remove it.
• Do not install lamps with a higher wattage than that for which this device was designed.
• Replace any deformed or damaged lamp with a lamp of the same type (see "8. Technical Specifications", p.8):
1. Unscrew the 3 screws at the top holding the vented lid and gently remove the lid.
2. Unscrew the 2 big screws on the socket and gently pull the socket out of its holder using the knob.
3. Remove the old lamp and carefully install a new one. There is only one way to install the lamp correctly.
4. Carefully reposition the socket and fasten the 2 big screws.
5. The position of the lamp can be adjusted with the 3 small screws on the socket to maximize light output.
6. Reposition the lid and fasten the 3 screws.
Remark: Do not operate the device when the cover is open.

check the device once a year and once before you bring it into service.

• 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.
