RISK OF EXPOSURE TO EXCESSIVE ULTROVIOLET (UV) RADIATION:
Change shields and lenses if they have become visibly damaged to such
an extent that their effectiveness is impaired, for example by cracks or
deep scratches.
Never look directly at the lamp while lamp is on.
Do not operate without complete lamp enclosure in place or when lens
is damaged. Serious injury may result from the generation of ozone by
this lamp system. A proper means of venting must be provided.
RISK OF POSSIBLE LAMP EXPLOSION:
Do not open for five minutes after switching off.
Service and maintenance should be performed only by qualified
personnel as determined by the high-pressure lighting fixture
manufacturer.
Wear eye and hand protection when re-lamping.
DANGER-INTENSE HEAT:
Equipment surfaces may reach temperatures up to 150° C (302° F).
Allow the fixture to cool before handling.
This equipment is designed for use with a Philips® MSR Gold SA/SE
metal halide lamp only. Use of any other type lamp may be hazardous
and may void the warranty.
