Special skills are necessary for installing this product. Be sure to ask the sales outlet or a service company (See the
User's Manual of your HITACHI projector) to perform the installation job.
Pay particular attention to the following points when mounting a projector on the ceiling.
1. Before performing the mounting design and construction work, verify that the weight of the projector and ceiling
mount with 6-axis adjustment (HAS-404U) can be fully supported.
2.
To protect itself, the projector has a temperature sensor that turns off the power if its internal temperature rises
abnormally.
Follow the instructions below to prevent the temperature from rising abnormally.
(1) Do not install in locations where the temperature is outside the operating temperature range indicated in the
projector's User's Manual.
(2) Avoid placing the projector in smoky, humid or dusty place.
(3) To facilitate ventilation from the exhaust outlet, allow for at least 50 cm of space around the projector.
(4) Do not install in locations that are subject to sudden changes in temperature, such as near an air conditioner, or
where the temperature exceeds the operating temperature indicated in the projector's User's Manual.
