RSA INSTALLATIONThreaded Pipe Installation1. Carefully determine required mounting location.IMPORTANT ! : This will require knowing the lens to screen distance. See projector specifications for details on determining this distance.2. Using a pipe wrench, install 1-1/2" NPT or NPSM following ANSI/ASME B1.20.1 (Schedule 40, 0.154" minimum thickness steel or aluminum - ASTM B221) threaded extension column (not included) into threaded collar until tight, with a minimum of four threads engaged.WARNING: IMPROPER INSTALLATION CAN RESULT IN SERIOUS PERSONAL INJURY OR DAMAGE TO EQUIPMENT! Structural membersMUST be capable of supporting five times the combined weight of all equipment being mounted.3. Align RSA with end of NPT pipe.4. Thread RSA up onto pipe by turning counter-clockwise until hand tight.

Rough Alignment of RSA1. Turn RSA clockwise or counter-clockwise until front of mount is facing target.IMPORTANT ! : When RSA is properly positioned, the set screw access hole should be pointing directly at target.(see bottom detail in figure at left)2. Secure RSA to pipe by turning set screw with a 5/32" hex key until tight.CAUTION: DO NOT OVERTIGHTEN! Over tightening of set screw can damage threads on pipe.

INSTALLATION

Wood Stud Installation
