WARNING
!
Do not attempt repair of this unit unless you are
familiar with the necessary tools, equipment, util-
ity 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 high-voltage power supply.
This allows the serviceman to replace a faulty component
rather than attempt repairs of such components in the
field.
The solid-state power supply is not
designed for individual component part
replacement and must be replaced as
a complete "snap-in" unit.
Input voltage: 120 VAC 50/60 Hz.
