CLEANING AND MAINTENANCE
Under normal running, the protective units of a projector should be inspected regularly like power fuse. If it is burned, please
install a new one and ensure it is the same rating as the burned one.
For a projector with an over-temperature protective unit, please inspect cooling units regularly like cooling fans, heat sink and
other cooling parts. Please check if the fans run normally or fans and air inlets are blocked by dust. To keep air inlets /outlets clean,
cooling fans should be cleaned every 15days.
For waterproof projectors, unless confirmed by a professional technician for the replacement of some internal components, it’s
forbidden to dismantle it. For the projectors like this, just keep them clean if no fans for cooling.
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. For a projector with high IP rating, if no damage inside, it is
advised to clean the surfaces of its housing in principle. Keep lens clean and do not touch optical parts with bare hands.
