Setting to Work
Safe service in use necessitates the strict observance of the following precautions.
◼
Any article fabricated from quartz or glass is inherently fragile and care should
therefore be taken, always, when handling lamps.
◼
Eye protection must be worn when handling lamps that have been removed from
their packaging materials.
◼
Ensure that the power rating of the lamp to be fitted is suitable for the lamphouse
and power supply equipment.
◼
Always isolate the equipment from the supply before inserting a lamp.
◼
Before inserting the lamp ensure that all contacts are clean. Contacts must be
renewed at the slightest sign of corrosion. Sanding or filing down corroded areas is
not recommended as this will only make the conducting surface between the pin
and lampholder smaller, thus causing the lamp to overheat.
◼
Do not twist or bend the fused quartz bulb when fitting the lamp as mechanical
stresses MUST be avoided.
◼
When inserting or removing a lamp, always hold it securely by its’ base
to prevent
breakage between base and bulb.
◼
The lampholder must not exercise mechanical tensions on the lamp, neither during
insertion nor operation. Contacts must not discolour during use.
◼
For safety reasons, the lamp should be replaced once it has reached its’ average
life, and not later than 1.25 times the stated life. With continuing use, the risk of the
lamp exploding increases due to alterations within the quartz.
◼
When fitting the lamp suitable protection must be worn i.e face mask and gloves
with wrist protection.
◼
Never touch the quartz bulb with bare hands, as fingerprints will make the glass
cloudy and cause a severe loss of light. This may also cause recrystallisation and
thus weaken the bulb material. Should the bulb be inadvertently touched, remove
fingerprints with methylated spirit and a clean, soft paper towel. The bulb should
then be wiped with distilled water. NOTE: ALWAYS WEAR MASK AND GLOVES
DURING CLEANING).
In all circumstances the lamp
manufacturer’s
data should be referred to when dealing
with lamps.
