AIR GUIDE
This guide contains service checks to assist service personnel
in locating and correcting any malfunction that might occur to
render the air cleaner ineffective or inoperative. The air cleaner
has been designed with replaceable components, such as the
high-voltage power supply and air flow switch. This allows the
serviceman to replace a faulty component rather than attempt
repairs of such components in the field.
