NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and the receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

Monitor Installation
Although the CleanAlert FILTERSCAN® Air Filter Clogging Monitor and
Alarm, Model FS-242, may be installed upstream, downstream, or
differentially across the air filter (using optional tubing kit Model CA-4DP),
the best results will be found when installing downstream of the air filter
(that is, between the air filter and the system blower fan, usually located at
the return duct of the HVAC system).
WARNING! Ensure that the HVAC system blower motor/fan is turned OFF
until told to otherwise!
1. The FILTERSCAN® Monitor is to be attached to the external wall of
the air duct, either upstream or downstream from the air filter to be

monitored. NOTE: The minimum distance for positioning the
FILTERSCAN
®
Monitor from the air filter is six (6) inches.
2. Locate an area on the return duct, preferably downstream from the air
filter (that is, between the air filter and the system blower), large
enough to place the Monitor template on a flat surface and where
there are NO obstacles inside the duct. There should be sufficient
clearance from the surrounding walls and from any components of the
air supply system.
3. Place the Monitor template at the location found in the previous step,
such that "TOP" is facing upward. NOTE: The FILTERSCAN®
Monitor front panel must be clearly visible when installed.
4. Using the template, drill one large hole, (3/8") for the sensor and four
small holes (7/64") for the mounting screws.
5. Attach the FILTERSCAN® Monitor by aligning its sensor tube with
the larger hole and secure the Housing using the mounting screws
supplied. The sensor tube does not extend into the duct.
6. Set the Upstream/Downstream switch so that it matches the
FILTERSCAN
®
Monitor position with respect to the air filter (that is,
OFF for upstream mounting or ON for downstream or differential
mounting). The switch can be accessed by removing the front cover
of the Monitor.

8. Wait for approximately 15 seconds (warm up and stabilization time).
9. Install a clean, new air filter into the HVAC system.
10. Depress the ZERO/CLEAN button ONCE. The STATUS LED will
blink yellow for several seconds while the FILTERSCAN® records
the system’s FAN OFF condition, then turn to blinking green. This

indicates proper operation and that you are ready to move to next
step. If the unit detects the zero air flow is out of limits, the STATUS
LED will blink red. In this case, check to see that the HVAC system
blower fan is OFF and no conditions exist during this part of the
calibration that would cause air to be moving within the HVAC ducts,
such as opening and closing of doors or windows. If no such
condition exists, contact the company that you purchased the
FILTERSCAN
®
from for repair information.
11. Adjust the thermostat temperature adjustment to either increase or
decrease the room temperature by at least four degrees, enough to
signal the HVAC system to turn on heating or cooling.
12. Once the HVAC system blower fan turns on, wait one minute for the
blower fan to stabilize.
13. Depress the ZERO/CLEAN button once. The STATUS LED should
turn from blinking green to blinking yellow for several minutes. This
indicates that the unit is calibrating itself to the air filter and HVAC
system into which it is installed. Once calibration is completed, the
STATUS LED will blink green a few times then turn off.
14. Return the thermostat to normal operating temperature. This
concludes the installation of the FILTERSCAN® Monitor.
15. The SERVICE FILTER control is a fine tuning adjustment that has
been calibrated to the mid-range, Recommended Setting at the
factory. This control allows the user to change the point at which the
clog alarm will be triggered. Turning the SERVICE FILTER adjustment
clockwise will cause the FILTERSCAN® to issue an alarm at a lower
level of filter clogging. Turning the SERVICE FILTER adjustment
counter-clockwise will cause the FILTERSCAN® to issue an alarm at a
higher level of filter clogging.
Receiver Installation – Wireless Option Only
1. Remove the front cover of the Receiver by depressing the latch at the
top of the Receiver housing, rotating the front cover downward, and
lifting the front cover out of the housing.

b. Test the Receiver by inserting a paperclip through the small hole in
the front cover of the Receiver until the click of a switch is felt, then
immediately pressing the SEND button on the Monitor. This
transmits a signal to the Receiver, which turns on the Red LED
and Beeper.
5. To insure proper operation when Receiver is placed in a desired
remote location, retest the Receiver as described above. This remote
procedure may require two people.

NOTE: Although the wireless transmission range is up to 100 feet,
it is greatest with no obstructions between the Monitor (transmitter)
and Receiver. Any obstructions, such as walls, floors, and ceilings
will reduce the range of transmission, and relocation of the
Receiver may be required. Retest with each location to ensure
proper operation
6. Mount the Receiver vertically by using the screws or adhesive strip
supplied.
7. Install the front cover by placing the bottom flanges into the housing
and rotating the cover upward until the top latches into the housing.

models (“C”) contacting your HVAC system electrician to have the power
to the Monitor cut. Wait for a minute and restore power. If your

unit is operating with both AC Adapter and batteries
installed, both will need to be removed in order to reset the malfunction. If
this does not reset the malfunction alarm, contact the company that you
purchased the FILTERSCAN® from for repair information.
Calibrating When Whenever a new air filter is installed, the FILTERSCAN
®
clog detector
Installing a New Air Filter system must be calibrated. Calibration establishes the clogged air filter
detection threshold based upon the condition recorded for a new air filter.
When a new air filter is installed, its condition is recorded and saved in
nonvolatile memory.
1. Insure that the HVAC system is OFF at the thermostat.
2. Remove the dirty air filter from the HVAC system.
3. Install a new, clean air filter into the HVAC system.
4. Make sure the FILTERSCAN® Monitor power is ON via either AC
Adapter or Battery installation, making sure the low battery indication
is not being displayed.
5. Depress the ZERO/CLEAN button on the FILTERSCAN® Monitor.
6. Wait for the red STATUS LED to illuminate.
7. Depress the ZERO/CLEAN button again.
8. Wait several seconds for the STATUS LED to change from blinking
yellow to blinking green.
9. Turn the HVAC system ON at the system thermostat.
10. Set the thermostat temperature adjustment to either increase or
decrease the room temperature by four degrees, which should be
enough to signal the HVAC system to turn heating or cooling on.
11. Wait one minute for the HVAC system blower fan to turn on and
stabilize.
12. Depress the ZERO/CLEAN button again.
13. Wait several minutes for the STATUS LED to turn from blinking yellow
to blinking green. During this time, the unit is recording the condition
of a clean air filter.
14. Wait several seconds for the blinking green STATUS LED to turn
OFF.
15. Return the thermostat to normal operating temperature.
Your FILTERSCAN® Monitor is now calibrated to the type of air filter you
have installed. Depending on the air filter type and manufacturing
tolerances, you may need to calibrate the FILTERSCAN® air filter
clogging detector each time a new air filter is installed.
