Step 5: Now take a pair of pliers/grips, and grip hold of
the very top of the tube (there is a small square in the
top section) and unscrew this from the main body of the
desiccator. See pictures below. The first picture shows the
small cap in place and the second one show it removed.
Warning - During this process you must not hold the white
section at all as it is extremely fragile and will break very
easily.
Step 6: Pour out the desiccant crystals and dispose of
them safely - and now replace with new crystals, and
again any spares must be disposed of safely (as per local
regulations regarding silica crystals). The top desiccator
should only require one of the smaller bags of desiccant
to fill it.
Step 7: The desiccator can now be put back together and
this is just a reversal of the removal process. When finally
screwing the desiccator back into the top of the ZephIR
it only needs to be tightened up enough to make a good
seal - do not over tighten as this could cause the threads
to be damaged.
Note - the best method is to finger tighten the desiccator
and then take the adjustable spanner and tighten it until
you feel the seal being made.
The remaining breather desiccator in this pod is located at
the rear of the unit under the upper louvre. As shown in
the picture below.
There is no hermetic seal between the upper window
of the optics pod and the lower module, the user can
therefore inspect the upper breather desiccator to establish
whether a replacement cartridge is required.
Step 1: First unscrew the desiccator from the rear of the
optics pod, by holding the main part of the desiccator and
twisting anti-clockwise.
Step 2: When the desiccator is fully removed then, using
a flat blade screw driver, remove the top section of the
unit to expose the desiccant crystals inside. Pour out the
crystals and dispose of them in a safe manner (as per local
regulations regarding silica crystals).
Step 3: Replace the desiccant crystals with the new ones
from the supplied packets - the desiccator should require
2 of the larger packets to fill it and dispose of any spare
crystal as previously described.
Step 4: Replace the top section of the desiccator and then
screw the desiccator into the back of the optics pod until
the seal is made - this should only need to be hand tight.
