TROUBLESHOOTING
SAFETY HAZARD
Failure to follow this caution may result in personal injury or
equipment damage.
The following instructions are for use by qualified personnel
only.
CAUTION
!
The air purifier is equipped with a power indicator light located on
the door (see Fig. 10). This power indicator light will illuminate
when the air purifier door is installed, the power switch is in the on
position, AND the fan coil blower is running. If the power
indicator light is not illuminated, follow the troubleshooting steps
below.
If the air purifier shuts “OFF” during normal
operations:
This condition could be caused by the power supply recognizing
that there is something wrong in the air purifier. The power supply
detects air purifier electrical faults and shuts off the high voltage for
50 seconds if such a fault is detected. If 4--6 faults have been
detected, the power supply will shut OFF and remain OFF. The air
purifier will not turn ON until the problem has been corrected by
the user and the unit has been reset per the instructions below.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
The following procedures will expose electrical components.
Disconnect power between checks and proceed carefully. Only
a trained, experienced service person should install and/or
troubleshoot the Infinity Air Purifier.
