CLEANING AND MAINTENANCE
The projector’s protective devices should be periodically checked. For example, check if the fuse is blown or not. If true, replace
it with a new fuse with same rating. Please be advised they be of same rating.
Please periodically check the cooling devices with the projector having protective unit for over-temperature
（
If over-temperature
occurs, the protective unit will trigger power-off automatically
）
. The cooling devices include cooling fan, heat sink and other
cooling components. Please check if the fan runs normally and the fan and the air-inlet and outlet are blocked by dust. Please
ensure that the air inlet and outlet are clean and clear. The cooling fan must be cleaned once every 15 days.
For those projectors with optical lens, reflector and coated color filters, it is necessary to make it clean for reliable operation
because of easy accumulation of smoke, oil and dust on the lens, thus decreasing the light output. Then internal optical lens, flat
glass, reflector and coated color filters must be periodically cleaned for optimal light output.
For the projector with some IP rating, unless approved by professional service people and internal parts requiring to be replaced,
it’s prohibited to dismantle it. For this type of projector, if without any fan, please keep it clean; if yes, please refer the above
mentioned method for cleaning.
The cleaning intervals depend on how often it’s used and its running environment. Use soft clothing and normal glass detergent
for cleaning. It’s advised the external optical system be cleaned once every 20days, internal optical system once every 30/60 days
at least. For the projector with higher IP rating, if there is no damage inside, just clean the projector’s surface in principle. Keep
the lens clean and don’t touch the optical parts with bare hands.
Special note:
It’s normal phenomena that there will be mild water mist on the lens while the waterproof product is in use.
