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
cordsuppliedthroughthesafetycordholes for safetysupport.
●Before any installation, maintenance and cleaning work, please ensure the projector is disconnected from
powermains.
●After running for 5minutes, the temperature ofthe housing of the projector is45℃.After stable operation , its
temperatureis80℃.
●While the lamp is stricken for the first time, there will be smoke and strange smell. It’s normal and does not

● Don’t touch the covers of the working projector(They are very hot!)
● While a lighting fixture works properly under normal ambient temperature, the maximum temperature of the
external surface of the control device(The integrated control device means the external surface of the housing of the lighting fixtures
electricchamber)allowed is75 Celsiusdegrees.

2. INSTRUCTIONS
●CLEANINGANDMAINTENANCE
The projector’s protective devices should be periodically checked. For example, check if the fuse is blown or not. If true, replace
it witha new fuse with samerating.Please be advised theybe of same rating.
Please periodicallycheckthecoolingdeviceswiththeprojectorhavingprotectiveunit forover-temperature(Ifover-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 thatthe air inlet and outlet arecleanand clear.Thecooling fan mustbe cleaned once every15 days.
For those projector with opticallens, reflector and coated colorfilters, 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 andcoatedcolor filtersmustbe periodicallycleaned for optimal light output.
For the projector with some IPrating, 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 methodforcleaning.
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.
