CrystalSix Operating Manual
2.1.2 Care of the Ceramic Retainer
CAUTION
Do not use excessive force when handling the Ceramic
Retainer Assembly since breakage may occur. Always
use the crystal snatcher.
To prevent scratching the crystal electrode, do not rotate
the ceramic retainer after installation.
Always use clean nylon lab gloves and plastic tweezers
for handling the crystal. This avoids contamination which
may lead to poor adhesion of deposited material to the
electrode.
Follow the procedure below to install or replace the crystals in the CrystalSix
sensor. (Reference
Figure 1-3 on page 1-6 ).
CAUTION
Rotating the unit in the wrong direction with the stops
disabled will cause severe damage! Do not rotate the unit
by hand to install the crystals or to check indexing.
1 Remove the heat shield (item #8) by gently pulling on the outside
circumference of the shield. The shield should snap off.
2 Since the crystal holders are packaged separately, skip the remainder of this
step for first-time installations. Using the crystal puller (IPN 750-279-P1,
provided in ship kit 750-268), remove the crystal holder by pushing the tips of
the crystal puller over the outside circumference of the crystal holder (see
Figure 2-2 on page 2-4 ). Gently pull the crystal holder from its receptacle. A
slight amount of pressure applied to collapse the tips of the crystal puller may
be required to extract the crystal holder.
3 Insert the tapered end of the crystal snatcher (part number 008-007) into the
ceramic retainer (A) and apply a small amount of pressure. This locks the
retainer to the snatcher and allows the retainer to be pulled straight out (B). See
Figure 2-1 .
