turns yellow as it nears exhaustion. The relative humidity of the output of the CI-301AD will
increase as the silica gel becomes exhausted. When this happens, replace the silica gel.
Use the same procedure described under Operating Instructions-Adding Consumable to refill
the silica gel tube. Replace the cotton ball filters (see Filters section below). Remember to gently
tap the tube to help settle the material. Keep all containers of fresh silica gel tightly sealed to
prevent absorption of ambient moisture.
The used silica gel may be discarded or dried in an oven. If the material is dried, it should be
placed in a sealed container before cooling.
Note that the indicator incorporated into the
silica gel may not function properly after this process, even though the silica gel itself may
be dry.
Water
Water should be added if the level falls significantly. Change the water if it becomes cloudy or
contaminated in any way. Empty the water tube if the CI-301AD is not used for more than one
or two days.
CO2 Cartridge
Screw the CO
2
cartridge into the regulator. Set the regulator to 6 psi. The cartridge may seem
to be tight before it is punctured, so make sure to tighten until there is pressure indicated on
the meter. The regulator must be set to “LO” to get a reading on the meter.
Filters
The cotton ball filters located at each end of the soda lime and silica gel tubes become clogged
with fine particles and must be replaced. These filters should be replaced each time the
chemicals are changed.
It is extremely important that the filters be kept clean at all times. The first indication of a
clogged filter will be instability in the output of the CI-301AD. This may be followed by a
reduction in the available flow.
