CAUTION: A CAUTION alerts you to the possibility of damage or destruction of equipment if you do not follow the corresponding instructions.

WARNING: Improper installation can result in serious personal injury! Make sure that the structural members can support a weight factor five times the total weight of the equipment. If not, reinforce the structure before installing the mount.

WARNING: Be aware also of the potential for personal injury or damage to the unit if it is not adequately mounted.

WARNING: The installer is responsible for verifying that the structure to which the mount is anchored will safely support four times the combined load of all attached components or other equipment.

WARNING: The weight of the display placed on the CMA-347 must not exceed 35 lbs. (15.88 kg), the maximum load capacity of the CMA-347.

CAUTION: Check the unit for shipping damage before you begin the installation.

INSPECT MOUNT BEFORE INSTALLATION

1.

Carefully inspect the mount for shipping damage

(see figure 1). If any damage is apparent, call your carrier claims agent and do not continue with the installation until the carrier has reviewed the damage.

NOTE: Read all assembly instructions before starting set-up or installation.

2.

Carefully inspect mount components for damage.

MOUNT INSTALLATION

The mount is shipped pre-assembled for applications under 15 pounds.

CAUTION: If the total combined weight of the projector, projector mount, and lower mounting pipe exceeds 15lbs, the CMA 347 vibration mount needs to be reconfigured for weights over 15lbs. Weigh all parts before beginning installation.

If the total combined weight of the projector, projector mount, and lower mounting pipe is 15lbs or below, proceed with mount installation. If the total combined weight of the projector, projector mount, and lower mounting pipe is over 15lbs, see Set-Up for Over 15 lbs on page 6.

NOTE: Keep the vibration mount as close as possible to the projector by minimizing the length of the lower mounting pipe.

1.

Thread Upper mounting pipe (190) into Ceiling plate

(180).

2.

Secure NPT 1 1/2” upper mounting pipe (190) to ceiling plate (180) following the installation instructions provided with the ceiling plate (180).

3.

Thread mount top (10) onto NPT 1 1/2” upper mounting pipe (190).

NOTE: Ensure there is no direct contact between mount and surrounding structure. Any contact could allow vibration transfer to the projector.

4.

Secure NPT 1 1/2” upper mounting pipe (190) to mount top (10) using 5/16-18 x 3/8" socket head set screw (160). Turn 5/16/18 x 3/8" socket head set screw (160) until it contacts thread of NPT 1 1/2” upper mounting pipe (190).

5.

Thread NPT 1 1/2” lower mounting pipe (200) into mount bottom (20).

6.

Secure NPT 1 1/2” lower mounting pipe (200) to mount bottom (20) using 5/16-18 x 3/8" socket head set screw (160). Turn 5/16/18 x 3/8" socket head set screw (160) until it contacts thread of NPT 1 1/2”

Installation Instructions lower mounting pipe (200).

7.

Thread projector mount (210) onto lower NPT 1 1/2" lower mounting pipe (200).

8.

Secure NPT 1 1/2” lower mounting pipe (200) to projector mount (210) following the installation instructions provided with the projector mount (210).

9.

With the weight of the installation on the CMA-347, tighten the 1/4-20 x 4" tap bolts until a slight preload is on the springs.

Installation Instructions

Set-Up

Set-up For 15 Pounds and Under

The mount is shipped pre-assembled for applications under 15 pounds. If the total combined weight of the projector, projector mount, and lower mounting pipe is

15lbs or below, proceed with mount installation.

(see MOUNT INSTALLATION on page 4)

For applications over 15 pounds, proceed to “Set-up For

Over 15 Pounds”.

If the mount has been previously set-up to accommodate a weight of 15-35lbs, it needs to be reconfigured to work properly with weights below 15lbs.

To set-up the mount for applications under 15lbs:

1.

Un-install mount following the instructions outlined in the Removal section of this document.

(see Mount Removal on page 7)

2.

Loosen and remove 1/4-20 Nylock nut (110), 1/4" fender washer (130), and stepped sorbothane damper (40) located underneath mount arm and set aside for reuse. (see figure 3)

3.

Slide 1/4-20 x 4" tap bolt (120) upward, out of mount top (10).

NOTE: Make cetrtain hardware group B (see figure 3) and (see figure 4) stays in place when removing

1/4-20 x 4" tap bolt (120) and associated hardware.

4.

Remove hardware group A (see figure 3) keeping

1/4-20 x tap bolt (120) for reuse in 0-15lb configuration.

5.

Install 1/4" fender washers (130), sorbothane dampers (50), and long medium gauge spring (80), onto 1/4-20 x 4" tap bolt (120). (see figure 4)

6.

Insert 1/4-20 x 4" tap bolt (120) with washers and dampers through mount top (10), group B hardware

(see figure 6), and mount bottom (20). (see figure 4)

7.

Install stepped sorbothane damper (40), fender washer (130), and Nylock nut (110) onto 1/4-20 x 4" tap bolt (120). (see figure 4)

8.

Tighten until a slight preload is on the springs.

Repeat steps 2 through 8 for the remaining two hardware sets.
