9.Secure main plate near top of bolts by threading nuts together. Make sure to leave plenty of space between plate and SL-151 to allow for easy access in later steps. (See Figure 6)

Attaching Main Plate and SL-151 to Ceiling Pipe

IMPORTANT ! : Only attach SMA-602 to UL Listed Chief ceiling mount SL151.

IMPORTANT ! : These installation instructions assume that a 1-1/2" NPT or NPSM following ANSI/ASME B1.20.1 (Schedule 40, 0.154" minimum thickness aluminum - ASTM B221) threaded extension column (not included) has been properly installed and is in place.

1.Thread top slide plate assembly onto ceiling pipe until it cannot be tightened any further. (See Figure 7)

2.Adjust top slide plate assembly back clockwise until set screw hole is facing target. (See Figure 7)

IMPORTANT ! : When SMA-602 is properly positioned, the set screw access hole should be pointing directly at target.

3.Insert 5/16-18 x 1/4" set screw (B) into access hole to secure top slide plate to ceiling pipe. (See Figure 7)

WARNING: Improper installation can result in serious personal injury or damage to equipment! The SL-151 projector mount weighs in excess of 50 lbs! Use either a mechanical lifting device or at least two people to lift and install SL-151.

4.Lift main plate and attached SL-151 underneath top slide plate making sure the four slots on each plate are perpendicular to each other. (See Figure 8)

5.Place bottom slide plate directly underneath main plate inserting four bolts through four slots in main plate.

6.Insert four bolts up through four slots on top slide plate and secure using the four hex nuts removed in Step 1 of Disassemble Pipe Adapter Assembly. (See Figure 8)
