Recommended Routing of Submerged Area/Velocity Cable
Proper routing of the cable serves two functions:
• Keeps the in-line desiccant assembly inside the cover and out of the way
when installing and removing the sampler from tight manholes.
• Keeps the desiccant out of direct contact with the elements. Also, keeps
water from dripping directly onto the desiccant assembly.
To secure the submerged area velocity cable, route the cable around the
battery and clip it under the battery hold downs.
