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.
8ADJUSTING TO SPECIFIC ROOM CONDITIONS
Program Setting 1: Service Indicator
The Service Indicator is used to predict when the filter will need cleaning (electronic air cleaners) or replacement (media air cleaners).
The Service Indicator automatically calculates the service interval based on the pollution level selected and the fan speed. If the filter becomes clogged the led • and •••• will flash each
time the air cleaner is turned on.
Pollution level guidelines for establishing setting:
• LOW DUTY: general pollution without tobacco smoke
••MEDIUM DUTY: moderate tobacco smoke concentrations
••• HEAVY DUTY: high tobacco smoke concentrations
•••• EXTREME DUTY: extremely high tobacco smoke concentrations
Program Setting 2: Resetting the Service Indicator
The indicator needs to be reset when the media filter is changed out. If led • and led •••• are flashing, it is time to change the
filter(s) and to reset the indicator.
To Reset:
