Installing Outboard Desiccant
Vented cable must be installed with outboard desiccant to protect the cable and
instrument electronics from condensation in high-humidity environments.
The desiccant can be removed from the vent tube, if necessary, to trim the conductor
wires. However, you must reinstall the desiccant after trimming and connecting the
wires.
1. Cut off the knot at the bottom of the vent tube extension.
2. Firmly attach the vent tube extension to the cable vent tube. Cover at least 6.4 mm
(0.25 in.) of the cable vent tube for a secure attachment.
3. Use the attached hook-and-loop strap to secure the desiccant to the cable, below
the stripped wires.
4. Remove the red dust cap from the black nylon cap to allow air to reach the cable’s
vent tube.

Using the Desiccant Refill Kit
1. Remove the black nylon vent cap from the top of the desiccant.
2. Pour out and discard the used desiccant. Check the glass wool in the bottom of the
container and replace if necessary.
The glass wool prevents the desiccant beads from falling out the
cable end of the desiccant pack. If the wool glass does this
effectively, there is no need to replace it when refilling the
desiccant.
