• This procedure must be performed by Christie qualified technicians.
• EXPLOSION HAZARD! Always wear manufacturer approved protective safety clothing (gloves,
jacket, face shield) whenever the lamp door is open or when handling the lamp. Any local or
federal specifications take precedence over Christie's protective clothing recommendations.
• Do not open the lamp door while the lamp is on.
• EXPLOSION HAZARD! Allow sufficient time for the lamp to cool down before powering down the
product, disconnecting it from AC, and opening the lamp door.
• EXPLOSION HAZARD! Do not stress the glass of a lamp or bare bulb in any way.

the lamp by the glass.

light beam of the projector.
Caution! If not avoided, the following could result in minor or moderate injury.
• Improper installation of the lamp can damage the projector.
• Incorrect lamp power supply and igniter connections can damage the product.

Light intensity hazard distance

This projector has been classified as Risk Group 3 as per the IEC 62471-5:2015 standard due to
possible hazardous optical and thermal radiation being emitted.
Warning! If not avoided, the following could result in serious injury.
• PERMANENT/TEMPORARY BLINDNESS HAZARD! No direct exposure to the beam must be
permitted.
• PERMANENT/TEMPORARY BLINDNESS HAZARD! Operators must control access to the beam
within the hazard distance or install the product at the height that prevents exposure of
spectators' eyes within the hazard distance. The hazard zone must be no lower than 2.5 meters
(US installations) or 2.0 meters (global installations) above any surface upon which any persons
are permitted to stand and the horizontal clearance to the hazard zone must be a minimum 1.0
meters.
• EXTREME BRIGHTNESS! Do not place reflective objects in the product light path.
The following show the zones for ocular and skin hazard distances.
