2.3.9 Detector Protective<br />
Barrier<br />
The liquid detector’s protective fluoroglass barrier (Figure 2-19)<br />
can be removed for cleaning or replacement. It is anchored by a<br />
hold-down panel on either side.<br />
Note<br />
The piezo film liquid detector is permanently attached to the<br />
pump base. If it is damaged, the entire pump base must be<br />
replaced.<br />
Barrier removal and<br />
replacement<br />
1. Remove the four self-tapping Phillips screws attaching<br />
the hold-down panels and pull them off.<br />
2. Peel the barrier away from the detector.<br />
3. Apply a thin layer of 737 RTV sealant (800-1002-03) to the<br />
outer edges of the mounting surface, taking care to avoid<br />
getting any in the tubing grooves.<br />
4. Install the new barrier, fitting the four inside holes over<br />
the insert guides, as shown in Figure 2-19.<br />
5. Reattach the two hold-down panels, pressing them down<br />
over the insert guides. Torque the self-tapping screws to<br />
7 - 10 in/lbs.<br />
