Step 1 Attach the top channel of the ceiling mount to the down-pipe by using the
following method:
1. Raise the top channel assembly and hand tighten the flange hub to the down
pipe.
2. Drop a socket head cap screw into a hole in the flange base.
3. Using one of the neoprene friction washers from the bottom arm as a pad
against the flange hub, jam a square shaft screwdriver between the hub and the

6. Pit the top support arms into the top channel assembly.
Align the four holes in the bottom channel of the ceiling mount with the holes in
the spanning rails. Push in the bottom support arms and secure the assembly using
the four M4 (metric 4mm) screws provided.
Open the top support arms of the ceiling mount sufficiently to accept the
equipment and finger tighten the securing screws and keep nuts in the top
channel.
Step 4 Ensure that the neoprene friction washers are attached to the threaded studs on
the lower support arm. Raise the equipment and lead the studs into the notches in
the top support arms.
