NOTE: The pre-filter may also be washed ONLY
if the COLLECTION CELLS show a "200/200-1".
Follow the same instructions to wash the PRE-
FILTER - being sure to tap gently and wipe off any
visible water droplets.
RESET TIMERS
When installed as part of a Communicating System with
a 900 series comfort control, the filter timer can be reset
at either the Comfort Control or the air cleaner.
To reset the PRE-FILTER timer at the comfort control
Select Filter 1 Change Reminder, then press the More
key to access the filter timer value and then press the
Reset key. For additional information please refer to the
Installers Guide and/or Service Facts for the 900 Series
control.
To reset at the air cleaner press and hold the RESET
key until the PRE-FILTER LED turns off (1 to 2
seconds).
To reset the Collection Cell timer at the Comfort Control
select Filter 2 Change Reminder, then press the More
key to access the filter timer value and then press the
Reset key.
To reset the Collection Cell timer at the air cleaner press
and hold the RESET key until the COLLECTION CELL
LED turns off (1 to 2 seconds).
If two air cleaners are connected on the same system,
reset all timers on both air cleaners at the same time to
the same settings. The comfort control will only report
one air cleaner timer and this methodology will allow the
air cleaners to remain on the same cleaning schedule.
Reset the filter timer at the comfort control using the
instructions given above.
FAULT CODES
The air cleaner LED's will display a fault indication,
three Yellow or three Red LED's, when a fault has been
detected. A log of the last three faults is recorded and
can be accessed by going into the Set-Up mode. The
unit will repetitively check the system to determine if the
fault persists. The fault indication will be displayed as
long as the fault condition remains.
If the fault is no longer present, the system will return
to normal operation and no longer display the fault
indication. Even if the fault has been cleared, a log of
the last 3 faults is recorded.
NOTE: If more than one whole house air cleaner is
installed, each unit will retain its own fault codes.
REPETITIVE ARC FAULT INDICATION
If the unit detects 10 consecutive run cycles where
an arc occurs during the cycle, it will go into a lock
out period for one hour. This is indicated by three
FLASHING YELLOW LED's. The PRE-FILTER and
COLLECTION CELLS should be cleaned to ensure no
large material is trapped in the filters and causing the
fault. Check the FIELD CHARGER for material that can
cause the fault.
If the unit detects any other type of fault, this will be
indicated by three FLASHING RED LED's. See the
Service Facts for fault code information.
