Since the projector is foreseen to be stacked while in the rigging frame, the minimum distance
space around the top and bottom air inlets should be the distance between two stacked projectors
while in the rigging frame.
Clean air environment
A projector must always be mounted in a manner which ensures the free flow of clean air into the projectors
ventilation inlets. For installations in environments where the projector is subject to airborne contaminants
such as that produced by smoke machines or similar (these deposit a thin layer of greasy residue upon the
projectors internal optics and imaging electronic surfaces, degrading performance), then it is highly advisable
and desirable to have this contamination removed prior to it reaching the projectors clean air supply. Devices
or structures to extract or shield contaminated air well away from the projector are a prerequisite, if this is not a
feasible solution then measures to relocate the projector to a clean air environment should be considered.
Only ever use the manufacturer's recommended cleaning kit which has been specifically designed for
cleaning optical parts, never use industrial strength cleaners on the projector's optics as these will degrade
optical coatings and damage sensitive optoelectronics components. Failure to take suitable precautions to
protect the projector from the effects of persistent and prolonged air contaminants will culminate in extensive
and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will be
noneffective and impracticable. Damage of this nature is under no circumstances covered under the
manufacturer's warranty and may deem the warranty null and void. In such a case the client shall be held
solely responsible for all costs incurred during any repair. It is the clients responsibility to ensure at all times
that the projector is protected from the harmful effects of hostile airborne particles in the environment of the
projector. The manufacturer reserves the right to refuse repair if a projector has been subject to knowingly
neglect, abandon or improper use.
Main Power requirements
The projector operates from a nominal mono phase power net with a separate earth ground PE.
Power requirements : 120-180V/200-240V (+/-10%), 16A-12A, 50-60Hz
The power cord required to connect the projector with the power net is delivered with the projector.
Projector Weight
Do not underestimate the weight of the projector. The projector weights about ±48 kg (±105 lb) without lens.
Be sure that the pedestal on which the projector has to be installed is capable of handling five (5) times the
complete load of the system. At least 2 persons are needed to lift the projector.
