Congratulations on having purchased a  product. You have assured yourself of a fix-
ture of the highest quality, both in componentry and in the technology used. We renew our
invitation to you to complete the service information on the previous page, to expedite any
request for service information or spares (in case of problems encountered either during, or
subsequent to, installation). This information will assist in providing prompt and accurate ad-
vice from your  service centre. Following the instructions and procedures outlined in
this manual will ensure the maximum efficiency of this product for years to come.

1. Presence of high voltage inside of the fixture. Insulate the projector from
mains supply before opening or performing any function which involves
touching the inside of the fixture, including lamp replacement.
2. For the connection to the mains, adhere strictly to the guidelines outlined
in this manual.

3. The level of technology of EXT Basic requires the use of special-
ised personnel for all service applications; refer all work to your autho-
rised  service centre.
4. Agoodearthconnectionisessentialfortheproperfunctioningoftheprojector.
Never connect the fixture if there is no earth connection.
5. Mains cables must not come into contact with other cables.
6. Do not operate the projector with wet hands or in an area where water is
present.
7. The fixture must never be located in an exposed position, or in areas of
extreme humidity.

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.
2. Always use a secondary safety fixing device with chain or steel wire of a

EXT Basic may be hung from an appropriate structure in any position or on tripod. If
hanging the fixture from a lighting truss or similar, we recommend the use of an appropriate
clamp “A”, as shown in the following diagram.
Always ensure that your support structure
and fixing (bolts, clamps, etc…) are rated to
support the weight of the fixture.

When hanging EXT Basic 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).

Follow these steps in order to configure the optical group properly:
1. Remove the two screws “” placed on both sides of the optical holder tube;

1. In order to adjust the tilt of the unit simply loose the side screw “B” on the yoke, adjust
the tilt and lock the yoke by tightening the screw again.

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


 Loose the thumbscrews “E” of the two lenses to set them at desired position. Turn on
the fixture and check if the desired focus and zoom lever are correct, then tighten the
thumbscrews;

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.
6. 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;
 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.

The use of a thermal/magnetic circuit breaker is recommended. Strict adherence to
regulatory norms is strongly recommended.
EXT Basic should not be powered through a dimmer as this may damage the in-
ternal switching power supply.
Prior to connecting the device to mains power, ensure that the mains characteristics are
within the recommended range for the use of EXT Basic.
All cabling and connections should be carried out by a suitably qualified personnel.

!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.

Even a thin layer of dust can reduce the luminous output and alter the consistency of the
beam. Regularly clean all filters and lenses using a soft cotton cloth, dampened with a spe-
cial lens cleaning solution.

Use a soft brush or a common vacuum cleaner or a source of compressed air for removing
dust. For the cleaning of the housing use a soft cloth and a non-aggressive cleaner. Check
that the internal fans and heat exchanger must be perfectly clean.
