cleaned annually by a qualified service professional.
CLEANING
Cleaning Instructions:
The air cleaner utilizes a PRE-FILTER and
COLLECTION CELLS. The purpose of the PRE-FILTER
is to capture large particles before they enter the
COLLECTION CELLS which allows the collection cells
to work more efficiently.
1. Turn the air conditioning system off at the Comfort
Control (thermostat).
s s WARNING
!
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.
2. Turn off power to the air cleaner by pushing and hold-
ing 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 approxi-
mately 15 seconds. Do not remove the door until
all the lights are off.
3. Disconnect the power/control cable.
4. Remove the Door Assembly from Whole Home Air
Cleaner by pulling away from the unit assembly.
Place on the flat and clean working surface with inte-
rior components facing up. See Figure 28.
5. Remove the PRE-FILTER (Figure 29) and/or the
COLLECTION CELLS (Figure 30) from the air
cleaner.
