4.1 MAINTENANCE AND CLEANING THE UNIT
• Make sure the area below the installation place is free from unwanted persons during setup.
• Switch off the unit, unplug the main cable and wait until the unit has cooled down.
• All screws used for installing the device and any of its parts should be tightly fastened and should not
be corroded.
• Housings, fixations and installation spots (ceiling, trusses, suspensions) should be totally free from any
deformation.
• When the lens is visibly damaged due to cracks or deep scratches, it must be replaced.
• The main cables must be in impeccable condition and should be replaced immediately even when a
small problem is detected.
• In order to protect the device from overheating the cooling fans (if any), and ventilation openings
should be cleaned monthly.
To ensure optimal operation and performance for a long time it is essential to periodically clean the parts
subject to dust and grease deposits. The frequency with which the following operations are to be carried
out depends on various factors, such as the amount of the effects and the quality of the working environ-
ment (air humidity, presence of dust, salinity, etc.). Use a soft cloth dampened with any detergent liquid
for cleaning glass to remove the dirt from the reflectors, from the lenses and filters.
It is recommended that the projector undergoes an annual service by a qualified technician for special
maintenance involving at least the following operations:
- General cleaning of internal parts..
- Restoring lubrication of all parts subject to friction, using lubricants specifically.
- General visual check of the internal components, cabling, mechanical parts, etc.
