●If a projector is not water and dust proof, while being operated it should not be under rains or in humidity to
avoid short circuit.
●Do not switch on and off a projector constantly in very short intervals, otherwise the light source’s and other
electrical parts’ life will be shortened .
●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 a projector is disconnected from power
mains.
● While running normally under normal ambient temperature, the temperature of the external surface of the metal
housing of a projector including that of the heat sink may reach
75
℃
at maximum.
●While the lamp is stricken for the first time, there will be smoke and strange smell. It’s normal and does not
mean a projector has some defects.
●While it running, don’t touch the metal housing to avoid being burned!
●Do not mount a projector directly on inflammable surface.
●Do not project the beam straightly on combustible items and the minimum distance between a projector
and illuminated items is 5m.
●A projector should be installed with good ventilation and the minimum distance between a projector and a wall
is 50cm. At the same time, please ensure the fans and air inlets and outlets are workable.
●Do not let the front lens under sunlight or other strong light sources at any angle, otherwise the danger of fire
can be caused by the focused beam by the lens inside a projector.

CLEANING AND MAINTENANCE
If a projector can’t start. Please check if the fuse is blown up. If it does, replace it with a new fuse with same ratings. And the
projector has over-temperature protective device. If the temperature is too high, the protective device will be triggered to shut the
projector off. When it happens, please check if the fans run normally or fan shield is blocked by dust. After the issue is solved,
restart the projector.
The accumulation of oil, smoke and dust on the lens will compromise the light output. Cleaning a projector is very
necessary to ensure a reliable use of it. Cooling fans need to be cleaned every 15days. Internal lens, reflector and hot mirror need
to be cleaned periodically to optimize light output.
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.
●
LUBRICATION
To ensure smooth movement of gobos and zoom and focus lens, it’s advised rotators’ bearings and 2 sliding bars for zoom and
focus lens be lubricated every 2 months. High quality and high temperature lubricant/grease is advised..
