Technical Repair Guide
WARNING: RISK OF ELECTRIC SHOCK
These servicing instructions are for use by qualified personnel
only. To reduce the risk of electric shock, do not perform any
servicing other than that contained in the operating instructions
unless you are qualified to do so.
This guide contains service checks to assist service personnel
in locating and correcting any condition 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 which allows the service person to
simply replace a component rather than attempt repair of
components in the field.

time the air cleaner is turned on.
