6.1 Overview

6.1.1 Cleaning

6.2 Desiccant

The 2105 is designed to perform reliably in adverse conditions
with a minimal amount of routine service requirements. To keep
your system working properly, you should check the desiccant
and channel conditions at regular intervals.
Maintenance intervals are affected by many variables. Humidity
levels obviously affect the service life of the desiccant, and the
amount of debris in the stream can drastically alter the channel
conditions.
Experience is often the best tool to use when establishing
minimum maintenance intervals for your system. Until you have
gained an understanding of the module's operation under dif-
fering environmental conditions, a weekly maintenance interval
is recommended.
The module case may be cleaned using a soft cloth, warm water,
and a mild detergent. Do not use an abrasive cleanser, or you
might scratch the surface of the case.
Before cleaning, make sure that all the protective connector caps
are in place to avoid damage to any of the connectors. You should
also ensure that no water or cleanser enters the desiccant unit.
The 2105 uses desiccant to protect the internal components from
moisture damage. The cartridge is filled with indicating silica
gel, which is blue or yellow when dry. As the desiccant becomes
saturated, the color changes from blue to pink, or from yellow to
green. Replace the desiccant before the entire length of the car-
tridge turns pink or green.
