Page 5: Installation Considerations
For any new installation, you may have to safely lift or hoist the projector into place. Securely wrap hoisting cabling and safety straps around the whole projector. Attach to the proper Christie ceiling mount only—never suspend or “fly” this model. WARNINGS Never stack projectors.
