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 inop-
erative. The air cleaner has been designed with replace-
able 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.
All voltage measurements indicated can be made with a
high voltage D.C. probe and a general purpose volt ohm
meter. For example: Simpson 260 or equivalent.
For test purposes, the air flow switch may be “wired out”
of the system. This will eliminate the need for air flow
across the sensing thermistor to energize the power
supply (see Fig 23).
NOTE: All tests to be performed with the Ozone Reduction
Jumper intact.
NOTE: When servicing the power pack components, all
wiring must be routed to factory specifications.
