Technical Repair Guide
•Press W: medium HV level (7300 V); leds • and •• are burning.
•Press W: low HV level (7100 V); led • is burning.
•Press V: to increase efficiency again up to maximum HV level (7900 V); leds •, ••, ••• and •••• are burning.
•Press PROGRAM: confirm setting 5 and go to setting 6.
Program Setting 6: Maximum fan speed remote control/ panel button
In setting 6 STANDBY led will flash six times every two seconds. Adjusting the maximum fan speed for remote control/panel button is very convenient for air cleaners installed in meeting rooms and open plan offices.
•Default: •••• (TURBO).

•Press PROGRAM: confirm setting 6 and go to setting 7.
Program Setting 7: Sensitivity adjustment Air Quality Analyzer
In setting 7 STANDBY led will flash seven times every two seconds.
Setting the sensitivity of the Air Quality Analyzer. The more sensitive, the quicker the reaction to changes in pollution level.
•Default: OFF (all leds are off), meaning the lowest sensitivity
•Press V: led • (LOW) will light up, meaning you've set the pollution sensitivity to low.
•press V: led •• (MEDIUM) will light up, meaning you have set the pollution sensitivity to medium.
•Press V: led ••• (HIGH) will light up, meaning you have set the pollution sensitivity to heavy.
•Press V: led •••• (TURBO) will light up, meaning you have set the pollution sensitivity to extreme.
•If you want to go back to one of the previous pollution sensitivity, press W.
•Press PROGRAM to confirm setting 7 and go to setting 8.
Program Setting 8: Time without high voltage after Service (Electronic Air Cleaners only)
In setting 8 STANDBY led will flash eight times every two seconds.
Setting a specific time for no high voltage after servicing is useful when the filter cells are damp or condensed in winter time. This setting will go back to default value if power is interrupted to the air cleaner.
•Default: OFF (all leds are off), when the air cleaner is switched on, there's always high voltage on the cell(s).
•Press V: led • (LOW) will light up, meaning you've set the time of no high voltage to 30 minutes.
•Press V: led •• (MEDIUM) will light up, meaning you've set the time of no high voltage to 60 minutes.
•Press V: led ••• (HIGH) will light up, meaning you've set the time of no high voltage to 120 minutes.
•Press V: led •••• (TURBO) will light up, meaning you've set the time of no high voltage to 240 minutes.
•If you want to go back to one of the previous time setting levels, press W.
•Press PROGRAM to confirm setting 8. The air cleaner will return to the normal running mode.
Reset to factory default
To reset the factory default settings:
Open the inlet grid, press the panel button (>>). While pressing the panel button (>>) close the inlet grid. Release the panel button (>>) when you hear two beeps.
Everything is now back into the default setting, except the Service Indicator (hours in use).
9 FILTER REPLACEMENT/CLEANING
See fig. 8 on page 25
In order to open the inlet grid (i.e. access the filter components), a narrow round screwdriver type tool will be needed (such as a torx type). The inlet grid is secured by two mechanical clips. To release these clips there are two access holes parallel to the control board faceplate on the inlet grid (approx. 3½" from the sides).
Insert the tool into the access holes and gently push further through some light resistance. This will allow the clips to be "unlocked" and thus the inlet grid will open easily.
DO NOT PULL THE DOOR OPEN WITHOUT RELEASING THE CLIPS.
9.1Prefilter replacement
The disposable prefilter can only be used once and cannot be cleaned. Do not turn the prefilter around since it can only be used in one flow direction.
9.2Electronic filter cleaning
A crackling or snapping sound will be heard occasionally during use of the air cleaner. This is normal and is caused by high voltage arcing in the filter. Cleaning the electronic filter is necessary when the crackling is heard frequently.
!CAUTION
CELLS MAY CONTAIN SHARP EDGES.
Use care when servicing unit or handling cells. Failure to do so could result in minor personal injury.
For maximum efficiency your air cleaner cell(s) should be cleaned regularly. When cleaning is required the following procedure should be used:
Cleaning the cell(s)
ATurn the air moving system OFF and disconnect the air cleaner from power. Wait 15 seconds for the collecting cell(s) to discharge.
BRemove the cell(s) and prefilter(s) from cabinet. Using a solution of warm water and low sudsing detergent, soak cell(s) for 20 to 30 minutes. Discard prefilter(s) and carbon filter(s).
NOTE: Ionizing wires may become coated causing loss of cleaning ability by the collecting cell. Using a damp cloth, wipe each ionizing wire, exercising care not to damage them.
