Step 1: Mounting the straps.
A. Unpack and disassemble the enclosure. Remove the Covers. Remove the Keepers.
Remove the Clamp assembly. Loosen the transducer clamping screw. Retain all
hardware for future use. See Fig 1-1, 1-2
B. Determine the correct spacing required as outlined in the FDC Menu and Field
Manual.
C. Place the assembly on the pipe and mark the pipe at each strap location using
chalk or a grease pencil. See Fig 1-3.
D. Prepare straps for mounting. Cut strap to length. Strap length should be twice the
pipe circumference plus 6 inches. Orient all hardware to the outside of the radius.
Remove setscrew from Screw-Lock Buckle. Retain for later use. See Fig 1-4
{Note: For
Reflect mode, install one keeper for each path (i.e. Dual Beam Reflect will have two
keepers at each strap location). For Direct-X mode install two keepers at each strap
location.}
E.
Mount the straps at the previously marked locations. Loop once around the pipe
and feed the open end of the strap through the Screw-Lock Buckle and the
Keeper/s as shown in Fig 1-5. Pull the loose end to remove most of the slack.
Continue with another loop around the pipe and through the Screw-Lock Buckle a
second time. Pull tight to remove slack.
Continue to Step 1-R for mounting in Reflect Mode.
Continue to Step 1-D for mounting in Direct-X Mode.
