Cleaning Procedure Ċ Interior. To clean the MPEG generator interior, perform the
following steps:
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 isopropyl
alcohol (75% solution) and rinse with warm deionized water. (A cotton-
tipped applicator is useful for cleaning in narrow spaces and on circuit
boards.)
STOP. If, after performing steps 1 and 2, a module is clean upon inspection, skip
the remaining steps.
3. If steps 1 and 2 do not remove all the dust or dirt, the MPEG generator may
be spray washed using a solution of 75% isopropyl alcohol by performing
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 the isopropyl alcohol and wait 60 seconds for the
majority of the alcohol to evaporate.
6. Use hot (120_ F to 140_ F) deionized water to thoroughly rinse them.
7. Dry all parts with low-pressure, deionized air.
8. Dry all components and assemblies in an oven or drying compartment using
low-temperature (125_ F to 150_ F) circulating air.
Lubrication. There is no periodic lubrication required for the MPEG generator.
