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.
8 ADJUSTING 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
To select the pollution level:
•Press
PROGRAM; you are in the program mode 1 and STANDBY
led will flash once every two seconds.
• Default:
OFF (all leds off).
•Press V: led • (LOW) will light up, meaning you've set the
pollution level to LOW DUTY.
•Press V: led •• (
MEDIUM) will light up, meaning you have set
the pollution level to MEDIUM DUTY.
•Press V: led ••• (
HIGH) will light up, meaning you have set
the pollution level to HEAVY DUTY.
•Press V: led •••• (TURBO) will light up, meaning you have set
the pollution level to EXTREME DUTY.
• If you want to go back to one of the previous pollution
levels, press W.
•Press
PROGRAM to confirm setting 1 and to go to setting 2.
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:
•Press
PROGRAM: you are in the program mode 2 and the
STANDBY led will flash twice every two seconds.
• Default:

leds switched on in setting 2, provided the Service Indicator
is in use for a while.
• Reset Service Indicator: press
OFF (all leds are off).
•Press
PROGRAM: all user settings are saved and the air
cleaner is back in normal control.
Program Setting 3: Maximum fan speed for Air Quality
Analyzer (

It is not possible to go directly to setting 3.
If the panel button (>> ) and then the
PROGRAM key are pressed
simultaneously before confirming setting 2, you're in setting 3
and STANDBY led will flash three times every two seconds.
Adjusting the maximum fan speed for the Air Quality Analyzer
is very convenient for meeting rooms and open plan offices.

TURBO).
•Press W and so on to go to the desired maximum fan speed.
•Press

low HV). This will increase the time between cleaning intervals.
• Default: high HV level (7600 V); leds •, •• and ••• are
burning.
