2-2-2. Terms for Preparation of Frames and Ceiling Hanging Brackets

Ask whoever is installing the projector to prepare a specifically designed frame and ceiling hanging brackets (Charged Service).
Take note of the following upon its design.
- There are intake openings and exhaust openings on the side of the main unit, exhaust openings on the rear, intake openings
on the front, intake openings on the top side. Make sure that the design does not obstruct these openings. Also make sure to
secure enough space to allow easy removal of the filter cover for cleaning the filter.
- Remove the adjusters on the main unit if they will interfere with the frame. The adjusters can be removed by turning them.
- Attach the frame and ceiling hanging brackets to the screw holes (in four positions) provided on the bottom surface of the main
unit for ceiling hanging installation.
Refer to the specification sheet for dimensions between the centers of the screw holes. Note that the screw holes on the main
unit have the dimensions of an M8 thread and a maximum depth of 20 mm (the lengths of the bolts are to be calculated accord-
ing to the design).
- Horizontal adjustment mechanism (for example, bolts and nuts in four positions)
- Design the frame so that it will not easily collapse.
- To prevent ceiling collapse, the ceiling should be able to support the combined weight (158 kg*
lens (8 kg) for an extended period of time, and the installation must be in accordance with any local building codes.
* When the light module NP-18LU01is installed, the weight is about 149 kg.
