CAUTION! IF CONSTRUCTING ADDITIONAL SUPPORT STRUCTURES TO INSTALL
THE LIGHT, THE LIMITATIONS AND REQUIREMENTS OF THE MRI ENVIRONMENT
MUST BE CONSIDERED. NON-MAGNETIC MATERIALS SHOULD BE USED. CONSULT
WITH YOUR MRI FACILITY MANAGER IF UNCERTAIN.
4.2.1 INSTALLATION OF THE EXTENSION ARM TO THE CEILING
For illustrations please refer to Figure 4 and 5. Attach the extension arm to the ceiling prior to connecting the
balance arm to the extension arm. The balance arm will easily be attached when the extension arm is
properly secured in the ceiling.
CAUTION! It is important that the extension arm with the mounting bracket is properly
aligned during installation. Failure to do so may cause drifting of the fixture.
1. Fasten the mounting bracket to the desired location using four (4), 3/8” x 2 1/4” (M10 x 60mm) lag bolts.
The ceiling joists/brackets and the bolts used in mounting, should support a minimum of 100 pounds (45kg)
pull on each mounting bolt and a minimum of 100 pounds (45kg) shear on each bolt. Pilot holes should be
drilled to ensure the lag bolts are not broken off during installation. A more secure mounting can be made
with machine bolts long enough to pass though the joists and held in place with a nut and washer.
2. Ensure that the extension arm is aligned by placing a level on the horizontal portion of the extension arm.
CAUTION: An attempt to mount the light in any manner other than one which is safe and
secure, can lead to problems, with possible injury to you or your patient.
* To ensure the ceiling rod is plumb, shim the bracket if necessary. Accurate alignment will enhance the
stability of the light and reduce drift.
* These minimum requirements are called for in order to support loads applied each time the light beam is
adjusted.
NOTE! An access panel in the drop/false ceiling should be constructed near the extension arm for potential
maintenance or adjustments post installation.
If sections of the drop ceiling around the extension arm are
easily removed, then this access panel may not be required.
