Interior Cleaning Procedure. Do the following steps to clean the generator
interior:
1. Blow off dust with dry, low-pressure, deionized air (approximately 9 psi).
2. Remove any remaining dust with a lint-free cloth dampened in ethyl alcohol
and rinse with warm deionized water. (A cotton-tipped applicator is useful
for cleaning in narrow spaces and on circuit boards.)
NOTE. If, after doing step 1 and 2, a module is clean upon inspection, skip the
remaining steps.
3. If step 1 and 2 do not remove all the dust or dirt, the generator may be spray
washed using a solution of ethyl alcohol by doing steps 4
through 8.
4. Gain access to the parts to be cleaned by removing easily accessible shields
and panels (see Removal and Installation Procedures).
5. Spray wash dirty parts with ethyl alcohol and wait 60 seconds for the
majority of the alcohol to evaporate.
6. Use hot (48.88_ C to 60_ C) (120_ F to 140_ F) deionized water to
thoroughly rinse boards and components.
7. Dry all parts with low-pressure, deionized air.
8. Dry all components and assemblies in an oven or drying compartment using
low-temperature (51.67_ C to 65.56_ C) (125_ F to 150_ F) circulating air.
Lubrication. There is no periodic lubrication required for this generator.
