EAGLE 2 Operator’s Manual Maintenance • 161
a small vial of aluminum oxide powder
40 cotton swabs
10 finger cots
Perform the following procedure to clean the PID lamp:
1. Verify that the EAGLE 2 is off.
2. Place the EAGLE 2 upside down on a flat surface or hold it upside down.
3. Unscrew the three case screws until they disengage from the top case.
They are captive screws so they will not fall off of the bottom case.
4. Turn the EAGLE 2 right side up and carefully lift the top case away from
the bottom case. Be careful not to lift it so far that it pulls on the main
PCB with the cable that connects the top case to the main PCB.
5. Lay the top case down next to the bottom case to allow access to the flow
system.
6. Locate the PID sensor adapter. It has a five wire cable and is normally
located next to the pump. The cable has a connector that mates to a PID
sub PCB that is installed on the main PCB. Figure 25 on page 137 shows
a PID sensor in a typical location.
7. Grasp the sensor adapter firmly and pull it out of the PID flow chamber.
Rock it back and forth gently if necessary to pull it out. Take care not to
pull the cable connector from the PID sub PCB.
8. The PID sensor protrudes from one end of the sensor adapter. Grasp the
PID sensor firmly and pull it out of the sensor adapter.
9. Place the PID sensor face down on a flat clean working surface.
NOTE: Do not touch the lamp window with your fingers as this may
contaminate the window with finger oil. At this point it is
recommended that the finger cots be used on the fingers handling
the lamp. Finger cots are included with the lamp cleaning kit.
