Dual enclosure - Reflect mount

Installation procedure
1. Install strap retainers and straps on pipe as shown.
Note
Where possible adjust the strap retainers in the 10 and 2 o'clock positions. See figure
below.
Figure B-31
2. Place the first enclosure housing stand offs over the strap retainers and slip into place. It
may be required to align or adjust the strap retainer studs to fit into their respective stand
off holes. Be aware of the flow direction and the upstream side (reference) and
downstream side (adjustable).
Note
When mounting enclosures maintain alignment of strap retainers. When more than one
path is installed, position the enclosure housing so the Reference sensor (REF) of each
path is on the same end of the pipe. Sensor ends should be facing each other.
3. Install strap retainer nuts and washers at every stand off location.
4. Tighten one end of the enclosure housing just enough to keep housing from moving.
Continue to reposition the other end of the enclosure housing until the housing is
centered.
5. Tighten the other strap retainer nut just enough to keep enclosure housing from moving.
6. Visually verify that the enclosure housing is in line with the pipe axis by comparing the top
edge of the housing to the linear axis of the pipe. Adjust if necessary.
7. Repeat above steps for all remaining paths.
8. Tighten and all stand off strap retainer nuts.
9. Repeat installation for second enclosure housing.
