3.1 Initial Inspection and Handling Guidelines
Upon receipt of the CS445, inspect the packaging for any signs of shipping
damage and, if found, report the damage to the carrier in accordance with
policy. The contents of the package should also be inspected and a claim filed
if any shipping related damage is discovered.
Care should be taken when opening the package not to damage or cut the cable
jacket. If there is any question about damage having been caused to the cable
jacket, a thorough inspection is prudent.
The model number and pressure range is etched on the housing. Check this
information against the shipping documentation to ensure that the expected
model number and range were received.
Gauge pressure (Vented) devices must always have a desiccant tube attached.
New desiccant is blue in color. As the desiccant material absorbs water vapor,
it begins to turn pink, and eventually white when fully expired. Desiccant
