●There are safety cord holes at the bottom of the base of a projector. In view of safety, please run the safety
cord supplied through the safety cord holes for safety support.
●Before any installation, maintenance and cleaning work, please ensure the projector is disconnected from
power mains.
●Under normal temperature, after being stable, the unit’s surface (the surface of the heat sink)temperature
will be 55℃
●While the lamp is stricken for the first time, there will be smoke and strange smell. It’s normal and does not
mean the projector has some defects.
●While operated, do not touch the metallic housing. It is very hot during operation.
●Do not mount the projector directly on inflammable surface.
●Do not project the beam straightly on combustible items and the minimum distance between the projector
and illuminated items is 10m.
●A projector should be installed with good ventilation and the minimum distance between the projector and
walls is 50cm. At the same time, please ensure the fans and air inlets and outlets are workable.
2. INSTRUCTIONS
●CLEANING AND MAINTENANCE
Before the normal use of the unit, its protecting device needs to be periodically checked . For example, check if the fuse is blown up.
If yes, replace it with a fuse with same ratings. Please be noted that it must be a fuse with exactly same ratings.
The unit has over-temperature protection device(if over-temperature, the device will shut off the power supply). Please periodically
check cooling system. The cooling system includes cooling fans, heat sink and other cooling components; please check if the fans
run normally. Check if the fans and air vents are free of blockage, making sure air vents are not blocked. The fans need to be
cleaned every 15day periodically.
For the units with optical lens, reflector and hot mirror, because of the accumulation of the smoke, oil and dust on the lens, the
light output will be compromised. For the reliable use of the unit, it is very necessary to keep it clean. Internal and external optical
lens, glass panels, reflectors and hot mirrors need to be cleaned periodically for the optimized light output.
The unit has water-proof function at some level. Unless it is confirmed by a qualified person for the replacement of some internal
components, dismantlement of it is forbidden. For the unit of this type, if without any cooling fan, just keep it clean. If with fans,
please refer descriptions above for cleaning.
Cleaning frequency is to be decided by operations and its environment. Use soft cloth and normal detergent for glass for cleaning
work. It’s advised external optical system be cleaned every 20days and internal optical systems every 30/60days. Keep lens clean
and do not touch optical parts with bare hands.
●Before any maintenance and cleaning, please ensure the project is off the power
●Only qualified person is allowed to do maintenance
●During maintenance and before maintenance, the projector must be off power.
●To avoid internal damage, sun light or other light mustn’t penetrate into the projector via front lens whether
it runs or not
●Do not use alcohol or other organic solvent to clean the housing to avoid damage.
●Do not use any solvent with chemical elements to clean color filters or hot mirror.
