SAFETY INSTRUCTIONS

1. Always follow the instructions set forth in this manual when installing the projector
using this bracket.

Improper or inadequate installation could cause the projector to fall and injure someone.

2. The installation must be secure enough to bear the weight of the projector, the ceiling
bracket, and other hardware indefinitely, and must also be secure enough to withstand
vibration.

Inadequate installation could cause the projector to fall and injure someone.

3. To ensure safety, all bolts and screws must be tightened securely.

Loose bolts or screws could cause the projector to fall and injure someone.

4. Use only the parts provided with the bracket, and any other parts (commrecially
available) that are specified in this manual.

Using other parts could cause the projector to fall and injure someone.

5. Do not modify the bracket or the parts provided with the bracket.

Modifying the bracket or the other parts could cause the projector to fall and injure someone.

6. Do not use damaged parts.

Using damaged parts could cause the projector to fall and injure someone.
If any parts become damaged, contact your dealer.

PMT-L21/PMT-H25

7. Make sure to leave enough open space around the unit to allow heat generated by the
projector to dissipate.

Failure to provide adequate space around the unit could cause the projector to overheat internally, causing a
fire.

8. Before replacing the lamp cartridge, always remove the projector (with the mounting
adapter attached) from the ceiling bracket.

Attempting to replace the lamp cartridge while the projector is attached to the ceiling bracket could cause
the projector or the ceiling bracket to fall and injure someone.

E-2

9. Never hang from the projector or the ceiling bracket.

Hanging from the projector or the ceiling bracket could cause the projector or the ceiling bracket to fall and
injure someone.

10. Do not install the projector in a location near an air conditioning vent or in a location
subject to vibration.

Such conditions could have an adverse effect on the projector, and could even cause a fire or electric shock.

11. Do not install the projector in a location that is subject to high levels of dust or
humidity.

Dust accumulating inside the projector could cause a short circuit that in turn could cause a fire or electric
shock.

12. Do not install the projector in a location that is exposed to direct sunlight or in a
location that is subject to extreme fluctuations in temperature (such as near an air
conditioner).

Such conditions can cause the projector housing to warp or to become discolored.

13. Do not wipe the exterior of the ceiling bracket with benzene, paint thinner or cleaning
compounds.

Svenska

Doing so could damage the finish.

14. Special techniques and experience are essential when installing the projector using
this bracket. Request that your dealer arrange to have the equipment installed. The
customer should never attempt to suspend the projector from the ceiling.

Improper installation could cause the ceiling bracket or the projector to fall and injure someone.

15. Once the projector is installed, safety checks should be conducted on a regular basis.

If the projector is used over an extended period of time, screws can become loose and the installation can
become weaker due to the passage of time, vibration, etc.

SCREEN SIZE AND SETTING-UP DISTANCE

The distance between the projector and the screen (16:9) determines the actual image size.

Recommended distance: 0.9 to 13.0 m (2.9 to 12.6 feet)

While referring to the table below, position the projector so that the image size is smaller than the screen
size.

Screen size (cm [feet])

30" (66 x 37 [2.1 x 1.2]) 0.9 to 1.2 [2.9 to 3.9] 5.0 to 5.1 [0.16 to 0.17]

* Distance and dimensions should be used as a guide for installation. The actual distance will vary depending on

projection conditions.

Notes

• The projection distance is the horizontal distance from the surface of the projector lens to the surface of the screen.

In the case of the LPX-500, the surface of the lens is recessed by approximately 3 cm from its exterior.

• Although the vertical angle of the ceiling bracket can be adjusted in a range of ±15°, a large angle adjustment may

distort the projected image. We recommend you to adjust both the angle of the ceiling bracket and the angle of the
screen.

• The lens of the LPX-500 allows a zoom ration of up to about 1.35. The image size at the maximum zoom setting is

about 1.35 times bigger than the image size at the minimum zoom setting.

• The image size will be reduced when keystone correction is carried out.

E-8

PMT-H25 height adjustment

The height adjustment pole for the PMT-H25 has holes spaced 3 cm apart that can be used to adjust the
height. When the bracket is shipped from the factory, the pole is set at the shortest height.
Follow the procedure described below to adjust the pole to the appropriate height. For details on the
appropriate height, refer to “SCREEN SIZE AND SETTING-UP DISTANCE” on page 8.

English

[Adjustment Procedure]

1 Remove the safety pin.
2 Loosen the nut, and then remove the height locking

screw.

Caution

• Removing the height locking screw will unlock the height

adjustment pole from the ceiling bracket. In order to ensure
that the height adjustment pole does not fall, always hold
the pole while performing this work.

3

Determine the correct position in accordance with the
height of the screen, insert the height locking screw,
and then hand-tighten the nut.

4 Securely tighten the four height adjustment pole

locking screws (M5) provided.

5 Securely tighten the nut that was previously hand-

tightened.

6 Be sure to insert the safety pin.

After adjusting the height, make sure that the
adjustment pole locking screws and the nut are all
tightened securely. Also make sure that the safety
pin has been inserted properly.

2 Tighten the bolts to secure the reinforcing

plate to a ceiling beam.

Cautions

• Make sure that the reinforcing plate is strong

enough to bear the weight of the projector and the
ceiling bracket.

• Use M8 bolts (commercially available).

Caution

• Use M8 bolts (commercially available) to install the ceiling bracket. Using any bolts other than M8 bolts could

cause the projector to fall.

Note to Dealers and Installers

For the customer’s safety, make sure that the location where the projector is to be installed is strong
enough to bear the weight of the projector, the ceiling bracket, and the other hardware before
installing the ceiling bracket.

4 Hang the projector from the ceiling bracket.

Slide the mounting guide pin all of the way into the notch on the projector mounting adapter. This pin is
only meant to support the projector temporarily, and does not hold the projector securely. Be careful that
the projector does not fall.

ADJUSTING THE PROJECTION ANGLE

Before adjustment

• Turn the projector on and project an image, following the instructions on the owner’s manual of the

projector.

• Set the appropriate projection method on “Installation” item in “Set up” menu. For the detail about the

setting, refer to the owner’s manual of the projector.

• First, select a projection size using the zoom feature, and then adjust the angle.

1 Adjust the horizontal angle.

Adjust the projector so that the projected image is centered horizontally on the screen, and then tighten the
horizontal angle adjustment screws (2 on the PMT-L21, 4 on the PMT-H25).
