LAMP (RE)PLACEMENT
In case of replacement of the lamp or maintenance, do not open the fixture within
10 minutes until the unit cools down after switching off. Always unplug the unit
before servicing! Always use the same type of spare parts (bulbs, fuses, etc.) When
replacing parts, please only genuine spare parts.
• Unplug the mains cable.
• Wait for about 10 minutes until the unit has
been cooled down.
• Unscrew the 2 knobs that close the lamp
compartment.
• On the inside you will see the lamp socket.
Tear the lamp socket gently out of the lamp
compartment.
• Unplug the old lamp. Hold the lamp socket
while unplugging the lamp instead of pulling
the cable!
• Hold the lamp socket while pressing the new
lamp gently in the socket.
Attention! There are 3 different lamp
versions so check the label on the backside
of the device to know which lamp should be
used.
Never install lamps with a higher wattage!
Lamps with higher wattage generate temperatures the device was not designed for. If the device uses a
lamp transformer, it will burn due to current overload.
• Don't touch the bulb with bare hands! This drastically shortens the lifespan of the lamp. If you touched
the lamp, clean it with a cloth and a little denatured alcohol. Wipe the lamp off before installing.
• Put the new lamp back inside the unit. Be sure that the wires don't touch the lamp.
• Close the lamp compartment.
• Done!
OVERHEAD RIGGING
Best installation distance:
A projection distance of +/- 5 meters from the wall is perfect. From this distance the projection will cover
an area between 2.3m x 2.3m and 3.2m x 3.2m, depending on zoom adjustment.
Important: The installation must be carried out by qualified service personal only. Improper
installation can result in serious injuries and/or damage to property. Overhead rigging requires
extensive experience! Working load limits should be respected, certified installation materials
should be used, the installed device should be inspected regularly for safety.
• Make sure the area below the installation place is free from unwanted persons during rigging, de-
rigging and servicing.
• Locate the fixture in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed at least 50cm from surrounding walls.
• The device should be installed out of reach of people and outside areas where persons may walk by or
be seated.

ENGLISH
• Before rigging make sure that the installation area can hold a minimum point load of 10times the
device's weight.
• Always use a certified safety cable that can hold 12times the weight of the device when installing the
unit. This secondary safety attachment should be installed in a way that no part of the installation can
drop more than 20cm if the main attachment fails.
• The device should be well fixed; a free-swinging mounting is dangerous and may not be considered!
• Don't cover any ventilation openings as this may result in overheating.
• The operator has to make sure that the safety-relating and machine-technical installations are approved
by an expert before using them for the first time. The installations should be inspected every year by a
skilled person to be sure that safety is still optimal.
OPERATING INSTRUCTIONS
• Once connected to the mains the device starts running.
• Point the projector to the wall and adjust the zoom to obtain the desired projection diameter.
• Now adjust the focus knob until you get a clear, well defined picture.
• Eventually adjust the rotating speed of the gobo with the potentiometer on the back of the unit (6).
• Regular breaks during operation are essential to maximize the life of this device as it is not designed for
continual use.
• Do not switch the unit on and off in short time intervals as this reduces the lamp life.
• The units' surface temperature may reach up to 85°C. Don't touch the housing with bare-hands during
its operation.
• Always unplug the unit when it is not used for a longer time or before replacing the bulb or start
servicing.
• In the event of serious operating problems, stop using the fixture and contact your dealer immediately.
• Important: Never look directly into the light source! Don't use the effect in the presence of persons
suffering from epilepsy.
MAINTENANCE
• Make sure the area below the installation place is free from unwanted persons during servicing.
• Switch off the unit, unplug the mains cable and wait until the unit has been cooled down.
During inspection the following points should be checked:
• All screws used for installing the device and any of its parts should be tightly fastened and may not be
corroded.
• Housings, fixations and installations spots (ceiling, truss, suspensions) should be totally free from any
deformation.
• When an optical lens is visibly damaged due to cracks or deep scratches, it must be replaced.
• The mains cables must be in impeccable condition and should be replaced immediately when even a
small problem is detected.
• In order to protect the device from overheat the cooling fans (if any) and ventilation openings should be
cleaned monthly.
• The interior of the device should be cleaned annually using a vacuum cleaner or air-jet.
• The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in which the fixture operates:
damp, smoky or particularly dirty surroundings can cause greater accumulation of dirt on the unit's
optics.
• Clean with a soft cloth using normal glass cleaning products.
• Always dry the parts carefully.
• Clean the external optics at least once every 30 days.
• Clean the internal optics at least every 90 days.
Attention: We strongly recommend internal cleaning to be carried out by qualified personnel!
