Maintenance
This chapter contains information for cleaning, inspection,
troubleshooting, and performance of this load.
Troubleshooting
Refer to this table when troubleshooting the load for aid in
isolating the problem, and for possible causes and remedies.
Cleaning
The outside surface of the load should be wiped free of dust
and dirt when necessary. The principal maintenance re-
quired by the operator will be to periodically wipe off the ac-
cumulated dust and lint from the radiator fins. Excessive
collection of dust and lint on the cooling fins will interfere
with the efficient dissipation of heat. If the teflon insulator
or metallic contact surfaces of the connector should become
dirty, wipe them off with a soft cloth. If it becomes neces-
sary to use a cleaner, use a contact cleaner that is self-
drying and leaves no residue on the inaccessible internal
parts of the connector.
