Replacing the APPI lamp drive assembly O-rings 4-13
3. Fit the lamp mounting flange to the APPI source enclosure side plate.
4. Use the 2.5-mm Allen wrench to tighten the four captive lamp mounting
flange securing screws.
5. Fit the APPI lamp drive assembly mounting shaft O-rings to the lamp
mounting flange.
Tip:
First seat the O-ring in the small radius at the bottom of the groove
in the source enclosure side plate, then use a suitable tool, having a
circular cross-section, to “roll” the remainder of the O-ring into the
groove.
6. Fit the mounting shaft insertion tool to the mounting shaft.
Caution:
The securing screws must each be sequentially
tightened a small amount until they are all fully tight; this
ensures that the lamp mounting flange is uniformly seated on
the APPI source enclosure side plate.
Caution:
Take care not to damage the APPI lamp drive assembly
mounting shaft O-rings when fitting them to the lamp mounting
flange.
