Model CMA-347 Installation Instructions

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”

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.
