6. Maintenance
periodic cleaning
The following periodic maintenance is highly recommended.
Before attempting any of the following, ensure that the mains
supply to the unit is disconnected.
safety glass and reflector
Even a fine layer of dust can reduce luminous output substantial-
ly. Regularly clean the reflector and glass using a soft cotton cloth
dampened with a specialised cleaning solution.
Replace the safety glass if there are any visible signs of damage,
cracks, or deep scratches.
air passages
The air passages should be cleaned approximately every 6
weeks; the period for this cleaning will depend, of course, upon
the conditions in which the unit is operating.
Suitable inistruments for performing this type of maintenance are
a brush and a common vacuum cleaner or an air compressor.
lamp
The lamp should be replaced if there is any observable damage
or deformation due to heat. This will avoid the danger of the
lamp exploding.
electrical components
Check all components for correct earth connection and the pro-
per attachment of all connectors, refastening if necessary.
mechanical components
Periodically check all mechanical components and housing for
physical damage, replacing them if necessary.
