F. AIR CLEANER OPERATION
s
s
CAUTION
!
Do NOT
operate the air cleaner during construction
or remodeling of a home. The air cleaner is designed
for use in normal living conditions to capture small
particles. The volume of dust and condensate in
the presence of chlorides and fluorides from paint,
varnish, stains, adhesives, cleaning compounds,
and cement creates a corrosive condition which
may cause rapid deterioration of the cabinet and
internal components of the air cleaner and the air
handler/furnace.
DISPLAY FEATURES (Figure 22)
The air cleaner display can be used for several
functions:
• Provide the homeowner the operating status of the
air cleaner, including an indication the PRE-FILTER
or COLLECTION CELLS need cleaning.
• The installer accesses the SET-UP mode to
change the time to clean settings for the PRE-
FILTER and COLLECTION CELLS as well as change
the Power Level setting.
• The unit will display fault codes for the homeowner
indicating there is a problem with the air cleaner and
various fault codes for the service technician to assist
in troubleshooting the problem.
Turn the air cleaner on by pushing the POWER button.
The backlit POWER and Filter RESET buttons will
illuminate along with the first Green LED
(G1)
indicating
24 Volt power is present to the air cleaner.
When the indoor fan is operating the first LED
(G1)
will slowly flash. This indicates the FIELD CHARGER
and COLLECTION CELLS have power and the unit is
operating normally. There is a 10 [12] minute time delay
between the indoor fan starting and LED
(G1)
flashing.
In normal operation, the air cleaner makes a slight
sound as the air passes through it and is cleaned. In
some applications, you may notice this sound coming
from the return air vent(s). If desired, this sound level
can be reduced with minimal impact on air cleaning
efficiency by reducing the power setting of the FIELD
CHARGER in the SET-UP mode.
NOTE: There is a 10 [12] minute delay after the
indoor fan operates, before the air cleaner starts to
operate, each time the power to the air cleaner is
turned off/on. This can be bypassed by going into
and then out of the SET-UP mode.
G. SET-UP MODE
A combination of RED, YELLOW, and GREEN LED's
are used to indicate the following settings. See Figure
23.
• The three GREEN LED's are used to indicate PRE-
FILTER cleaning interval. This is measured in actual run
time of the indoor fan. The default setting is 2 months
[10 weeks]. See Figure 24.
• The four YELLOW LED's indicate the COLLECTION
CELLS cleaning interval. This is measured in actual run
time of the indoor fan. The default setting is 6 months
[31 weeks]. See Figure 25.
• The three RED LED's indicate the Power Level
setting. The default is maximum. See Figure 26.
INSTALLER SET-UP MODE
To enter the
SET-UP
Mode press and hold both the
POWER and RESET buttons for a minimum of 5 [6]
seconds. The current settings are then displayed. See
Figure 23. If this is the desired setting or at any time you
want to exit the SET-UP mode, press and hold BOTH
the POWER and RESET buttons for a minimum of 5 [6]
seconds to exit.
To change any of the settings, press the POWER button once.
PRE-FILTER SETTING (Figure 24) 24V Mode
Only.
One or more of the GREEN LED’s will come on
indicating the PRE-FILTER cleaning time setting.
Repeatedly press the RESET button to cycle through
the time options for the PRE-FILTER cleaning cycle until
the desired setting is displayed. Press the POWER
button once to accept that setting and move to the
COLLECTION CELL cleaning settings.
