Fasten The Cabinet To The Furnace
Align the cabinet with the return air opening. Place blocks
under the cabinet, as necessary, to make sure the unit sits
securely. Create an opening in the furnace to match the
cabinet opening. Attach the cabinet securely to the furnace.
Attach the unit directly or fit a starting collar in the furnace
opening. Either drill holes and fasten with sheetmetal screws
or rivets, or use slip joints. If you are drilling holes, use a
locking pliers to help hold the unit in place during drilling.
Install Turning Vanes
Install turning vanes to help distribute air equally over the full
surface of the upstream side of the media. Install them
whenever an abrupt 90 degree elbow is installed directly
against the media air cleaner cabinet.
Fasten Cabinet To Ductwork
Fasten side of cabinet to the ductwork using sheet-metal
screws, rivets, or slip joints, as appropriate.
Connect Ductwork
Connect the vertical duct section to the elbow. If the vertical
drop of the duct is less than 7 in. (178 mm) from the side of
the furnace, shorten the horizontal trunk or attach an offset
fitting to the elbow. See Fig. 12. When ductwork is properly
aligned, connect the vertical duct to the horizontal trunk.
Seal Joints
Seal all joints in the return air system between the media air
filter and the furnace to prevent dust from entering the clean
airstream.
Install Filter Cartridge
Slide the filter cartridge into the cabinet, making sure the
arrow on the cartridge points in the direction of air flow.
Replace access door. Insert the tab on the bottom of the door
into the slot in the cabinet. Swing the door closed and press it
into place.
Install W8600A AIRWATCH™ Indicator
Mount the W8600A next to the thermostat or any other
convenient location in the living area of the home. The device
is battery-operated so has no electrical requirements.
Remove the device from the base and mark the mounting
holes, using the base as a template. Drill the holes. Position
the base over the holes and install the mounting screws
provided. Tighten the screws until the base is mounted firmly
on the wall. Replace the device onto the base.
Set the DIP switches on the back of the W8600A according to
the equipment installed in the home. Use the default settings
when all devices (air cleaner, UV air treatment system, and
humidifier) are installed. Or move the DIP switch to off (left)
when a device is not installed.
NOTE: The UV air treatment system and the humidifier set-
tings are set for one year. The air cleaner settings
are selectable according to homeowner activities and
schedule.
Set the air cleaner filter time DIP switches for 3, 6, 9 or 12
months according to the information on the back of the device.
Leave the factory default DIP switch settings to change the
filter every three months. If no air cleaner filter is installed,
move DIP switch 4 and 5 settings to off (left).
Install two AAA alkaline batteries (provided) in the harness on
the back of the device. Observe that the device performs a
self-test, beeping and flashing the LC display individually for
each device (air cleaner, UV air treatment system, humidifier)
installed in the home. Then press and hold the black reset
button on the bottom of the device for five seconds or until the
display stops flashing to start the timers. Observe the battery
LCD: on solidly means that the unit is correctly powered;
flashing indicates that the battery requires replacing.
CHECKOUT
Visually check the installation. Make sure:
• Airflow is in the direction of the arrow on the media air filter
cartridge.
• Turning vanes and transitions, if used, are properly
installed.
• Joints in sheet metal between media fir filter and furnace
are sealed.
• All sheet metal connections are complete.
• Original furnace filter has been removed and blower
compartment is cleaned.
Replace any access doors removed during the Installation or
Checkout.
Run the furnace or cooling system through one complete
cycle to make sure the system operates as desired.
Maintenance
The W8600A beeps every fifteen minutes when an LCD is
flashing. Replace the part in the system that corresponds with
the flashing LCD.
NOTE: When batteries need replacing, replace them within
30 seconds of removal to maintain the correct
indicator time. After 30 seconds of replacing the
batteries, if the LCD is blank, remove and install new
batteries. For other parts, press and hold the black
button on the bottom of the device to reset the timer
after replacing parts.
The media filter must be replaced when pressure drop across
the media filter reaches 0.5 in. w.c. (0.1 kPa). or at least
annually. If the media air cleaner is installed downstream from
an atomizing humidifier or if the installation includes both
heating and cooling, more frequent replacement may be
necessary. Clogged media must be replaced promptly to
avoid restricting airflow and reducing efficiency of the heating-
cooling system. Record the replacement date in the space
provided on the replacement media filter.
