4.4 TO CHECK IF ANY OF THE STATUS LIGHT IS BROKEN
The working of status lights can be checked by turning off the
AAVI
®
IonJet2000
air purification
unit and then re-starting the unit. The automation system activates all status lights ON for a few
seconds at the system start-up phase.
4.4.1 WARNING: Green status light is ON and Red status light is BLINKING
TWO POSSIBLE REASONS FOR WARNING.
1. One of the high voltage units is not operating as specified, or
2. The temperature around the high voltage units is not as specified. If the warning state stays
active even though the air temperature is dropping, please call for the authorized AAVI
service.
In normal case the low temperature should not be possible due to the heat generated by the
high voltage units.
HIGH TEMPERATURE WARNING MIGHT APPEAR IF
1. The intake air temperature is high and
AAVI

purification unit is placed in direct
sunshine
2. One of the high voltage cooling fans in the electric box is broken.
3. The air guides inside the purification device don’t spread the warm air around the multiple
cleaning tubes for proper cooling to take place.
4.
AAVI

purification unit is de-activated. Maintenance is needed. Possible reasons:
1. 2 or more high voltage units’ state is not as specified.
2. The temperature around the high voltage units exceeds critical level.
Please call for the authorized AAVI service.
