!WARNING
Do not attempt repair of this unit unless you are familiar with the necessary tools, equipment, utility connections and potential hazards.
Repair should be performed only by a qualified service provider.
Failure to do so could result in reduced perfor- mance of the unit, serious personal injury or death.
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
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 Reduc- tion Jumper intact.
NOTE: When servicing the power pack components, all wiring must be routed to factory specifications.
