CrystalSix Operating Manual
Figure 2-1 Using the Crystal Snatcher
4 Invert the crystal holder and the crystal will drop out. (Skip this step for first-time
installations.)
5 Install the new crystal per section 2.1.1 on page 2-1 and section 2.1.2 on page
2-2 .
6 Using clean nylon gloves, grasp the edge of the new crystal with a clean pair of
plastic tweezers. Orient the crystal so the patterned electrode is facing up.
Gently insert the edge of the crystal beneath one of the wire segments that
protrude into the crystal cavity. Release the crystal.
7 Replace the ceramic retainer. Initially orient it at an angle to displace the spring
wire segments in the crystal holder.
8 Release the crystal snatcher with a slight side-to-side rocking motion. Using the
backside of the crystal snatcher, push on the ceramic retainer to ensure it is
completely seated.
9 Position the crystal holder between the tips of the crystal puller as illustrated in
Figure 2-2 .
10 Push the crystal holder into the receptacle of the CrystalSix sensor until
completely seated. “Snap” the crystal puller to one side to release the crystal
holder from the crystal puller. Using the non-slotted end of the crystal puller,
apply pressure to the crystal holder until it is completely seated. Verify that the
crystal fail signal on the controller display disappears. If the crystal fail signal
does not disappear, consult
section 4.5 on page 4-9 .
11 Press the crystal switch button on the hand held controller or the controller front
panel. The sensor will advance to the next crystal position. Repeat procedure
from Step 2 until all six new crystals have been installed.
12 Install the heat shield (item #8) by first orienting the slot in the heat shield to
accommodate the water tubes, then secure the heat shield by applying
pressure near the center of the shield. The shield should snap in place.
