1. Never locate the fixture on any flammable surface.
 Minimum distance from flammable materials: 0,5 m.
 Minimum distance from the closet illuminable surface: 0,5 m.
 Connect the projector to mains power protected by a thermal magnetic circuit
breaker.

1. The projector must always be installed with bolts, clamps, or other fixing devices
which are suitably rated to support the weight of the projector.
 Always use a secondary safety fixing device with chain or steel wire of a suitable
rating to sustain the weight of the unit in case of failure of the principal fixing
point.
 The external surfaces of the unit, at various points, may reach 60°C. Never han-
dle the unit until at least 10 minutes have elapsed since the LED was turned off.
 Never install the fixture in an enclosed area lacking sufficient air flow; the ambi-
ent temperature must not exceed 40°C.
5. The projector contains electronic and electrical components which must under
no circumstances be in contact with water, oil or any other liquid. Failure to do
so will compromise the proper functioning of the projector.

excluded from the warranty.
 Warranty expires when the projector is opened by unauthorized personnel.
 Warranty doesn’t include the replacement of the fixture.
5. Serial number and model of the fixture are necessary to retrieve informations and assistance
from the dealer.
 

Always ensure that your support structure

When hanging it is recommended to use a safety chain, as required by current legislation. The
safety chain must pass through the handles of the unit and then attached to the structure.
If using steel cables and chains not ’s production, make sure they are suitable to support the
weight of the unit according to normative UL/ETL (required: the weight of 6 complete devices
for at least one hour).

Before closing the cover after each
cleaning or adjustment, remember
to heat the LEDs for at least 20
minutes, to be sure to eliminate all
traces of humidity inside and make
sure that the sheaths remain in
their seat to avoid infiltrations.

5. It is possible to insert the gobo, to do so unscrew the thumb screws “I”, at this point it will be
possible to extract the gobo holder “K”. Insert the gobo by loosening the 4 screws “L”, at this
point we suggest you to unscrew 2 of them on one side in order to lift the gobo holder and
insert the desired gobo “M”. Once done, screw all the 4 screws and reinsert the gobo holder
and retighten the thumb screws.

7. Reassemble the projector by pushing the optical holder tube on the optical group and tighten
the screws that has been removed at the beginning.
 When putting the screws, be careful not to tighten too much, otherwise it may deform the
base of the optical holder tube.
 Use the hole that you can see above and under the projectors, in it there is a screw and by
unscrewing it you can adjust the optical group’s position by rotating it, tighten the two screws
symmetrically with each other in order to keep straight your optical group;

After having followed the preceding steps described, proceed with the power supply and turn on
the projector connecting it to the mains power.
The software version installed on the internal microprocessors will be shown on the display, sud-
denly it will show the current DMX addressing. If the address blinks, it means that the DMX signal
has not been received. Check the connection cable and the mixer functioning.

means that it will respond to the commands from channel 1 to channel 5 of your DMX 512

on. The operation must be carried out on every  which has an address different
