Fault Indicators; System Information - American Standard AccuClean Information Manual

FAULT INDICATORS

In communicating systems, the whole house air cleaner
faults are reported to the comfort control. When an alert
is present on the comfort control, see the Alert Code
Addendum that is shipped with the comfort control to
view the corresponding alert code and if it is related to
the whole house air cleaner.
The air cleaner has been designed to continually
monitor itself to insure it is working properly. If it detects
a problem, three of the four YELLOW LED lights will
flash continuously. See Figure 23.

WARNING
L !
High Voltage is present within the air cleaner for
operation. Before removing the Power Door, turn
the power off and wait at least 15 seconds to allow
voltage to discharge. Failure to follow instructions
could result in death or serious personal injury.
If this fault occurs:
1) Turn off power to the air cleaner by pushing and
holding the POWER button for three seconds.
The LED's will remain on until the voltage has
discharged and it is safe to remove the door. This
requires approximately 15 seconds. Do not remove
the door until all the lights are off.
2) Clean both the PREFILTER and the COLLECTION
CELLS to insure no large material is trapped in
the filters and causing the fault. See pages 4-9 for
cleaning information.
NOTE: If collection cells are wet, you may see this fault
indication. Turn air cleaner off until collection cells are
completely dry.

SYSTEM INFORMATION

CAUTION
L !
Before cleaning the coil or ducts in the air handler
or furnace, remove the COLLECTION CELLS, FIELD
CHARGER, and PRE-FILTER from the air cleaner.
Chemicals used during the cleaning of the air
handler, furnace, or ductwork can damage the air
cleaner components and degrade the performance
of the air cleaner.

Do not install air cleaner where the filter can be
exposed to UV light. UV light can cause the plastic
material to deteriorate, which may lead to filter
damage.
