F. AIR CLEANER OPERATION

▲

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 24)

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 PO

ER button.

The backlit PO

ER and Filter RESET buttons will

illuminate along with the first Green LED

(G1)

indicating

24 Volt power is present to the air cleaner.

hen 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, YELLO

, and GREEN LED's are

used to indicate the following settings. See Figure 25.
• 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 26.
• The four YELLO

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 27.
• The three RED LED's indicate the Power Level
setting. The default is maximum. See Figure 28.

INSTALLER SET-UP MODE

SET-UP

Mode press and hold both the

ER and RESET buttons for a minimum of 5 [6]

seconds. The current settings are then displayed. See
Figure 25. If this is the desired setting or at any time you
want to exit the SET-UP mode, press and hold BOTH the
PO

ER and RESET buttons for a minimum of 5 [6]

seconds to exit.

To change any of the settings, press the PO

ER button

PRE-FILTER SETTING (Figure 26)

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
