If you are signing up and configuring more than one monitor, press the “Add Monitor” button on the
Home page and provide the information for the additional monitor(s). You are now done.
For more detailed instructions on how to sign up and configure your monitor on the AirFilterSentry
website, consult the FILTERSCAN WiFi Installation and Reference Manual.
STEP 2: CONNECT TO THE AirFilterSentry™
Remove the front cover of the monitor by pressing on the sides of the housing. The inside of the
monitor is shown below.
Using proper electrical conduit, connect the monitor to the HVAC system’s auxiliary 15-24V AC or DC
power supply. Consult the picture above for the location of the AC/DC power terminals. This should
ONLY be done by a licensed electrician or HVAC technician. WARNING! Failure to follow all
instructions may result in electrical shock and serious personal injury. DO NOT CONNECT IF THE HVAC
SYSTEM’S AUX POWER HAS ANY LEG CONNECTED TO EARTH GROUND! When you do, a number of
LED's on the monitor’s printed circuit board will start to blink. Wait about one minute until the blinking
has stopped. There will be a red STATUS LED on at the upper right in the figure above, and a green
LED on at the lower right in the figure above.
Determine whether your router has a WPS button and where it is located on your router. If your router
does not have a WPS button, you will need to connect the monitor to the AirFilterSentry server using
the procedure found in the Section “Connecting Your FILTERSCAN WiFi Air Filter Monitor with your
Wireless Router without a WPS Button” in the Installation and Reference Guide. Once you complete
that procedure, skip to Step 3 below.
Depress the WPS button on your wireless router and hold it for two to ten seconds, until its LED
begins to blink.
Using a pencil eraser, toothpick, or other non-metallic object, depress the monitor WPS button (see the
figure above) just once until you feel it “click” and immediately release it. The WiFi Status Indicator will
start blinking green, then amber, and then green again. If the WiFi Status Indicator only blinks green or
amber before it goes off, and never blinks red, it has successfully paired with your router. Go to Step 3.
If the WiFi Status Indicator blinks red before it goes out, a problem has occurred in connecting your
monitor to your wireless router or to the AirFilterSentry server. Please go to the “WiFi Status
Page 3
Indications Table 1” in the Installation and Reference Guide to find the source of the problem. Once you
have corrected the problem, return to Step 2 and try to connect again.
If the WiFi Status Indicator continuously blinks amber, the software is being updated. Please wait until
the blinking stops, approximately two minutes.
STEP 3: INSTALLING YOUR FILTERSCAN WiFi Home Air Filter Monitor
It is suggested that a licensed technician perform the installation.
WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions may
result in electrical shock and/or serious personal injury.
With the cover still off, temporarily hold the monitor on the RETURN air plenum of your central air
conditioning system or forced-air furnace. Use a pencil eraser or other non-metallic object to press the
Send button on the printed circuit board. See the diagram above for the button’s location. The WiFi
Status Indicator will begin to blink green, then amber. If it goes off without blinking red, the monitor is
able to communicate with your router from that location and you can install the monitor there. However,
if the WiFi Status Indicator blinks red before going off, the signal between the monitor and router is too
weak. You need to move your router so that either they are closer together or there are fewer
obstructions (walls, ceilings, etc.) between them. You can also try rotating your router so that a different
side faces in the direction of the monitor. After making these adjustments, press the Send button again
and see if you can get the monitor and router to successfully communicate with each other. If none of
these adjustments work, your remaining option is to add a WiFi router “repeater” or “range extender” to
your home WiFi network. These devices are placed between your router and the monitor and “extend”
the signal between them. We strongly recommend you get one with a WPS button. Once you install it,
repeat Steps 2 and 3, treating the range extender as if it were your router.
Consult the Read This First document and determine whether you are going to mount the monitor
upstream or downstream of the air filter. Set the Upstream/Downstream switch (SW4-2) to ON for
downstream mounting or OFF for upstream mounting.
WARNING! Ensure that the HVAC system blower motor/fan is turned OFF until instructed otherwise!
Locate a spot on the RETURN side of your central heating and cooling system – preferably between
the air filter and the system blower – that is large enough for you to place the monitor template on a flat
surface and is free of obstacles inside the duct. NOTE: The minimum distance for positioning the
FILTERSCAN® WiFi Home Air Filter Monitor from the air filter is six (6) inches. And, there should be at
least 6” of clearance from the surrounding walls and from any other components of the system.
Tape the monitor template on the system such that "TOP" is facing upward. Use a center punch to start
each hole. Drill one 3/8" hole for the sensor and four 7/64" holes for the mounting screws. Use care
when drilling to insure no internal parts are damaged by the drill.
Place the monitor over the holes and align its sensor tube with the larger hole. Attach the Housing to
the air plenum using the mounting screws supplied. Note the sensor tube does not extend into the duct.
Replace the front cover on the monitor.
STEP 4: CALIBRATE YOUR MONITOR
Install a clean, new air filter into your heating and cooling system.
1. After power is first applied, wait for approximately 15 seconds (warm up and stabilization time).
2. Turn the HVAC system OFF at the thermostat. Ensure the HVAC system blower is turned OFF and
that 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.

3. Install a clean, new air filter into the HVAC system.
4. Depress the RESET button, holding for two seconds until the STATUS LED turns Green and a
beep is heard.
a. After approximately ten seconds, the STATUS LED will blink yellow for approximately 20
seconds while the FILTERSCAN WiFi Home Air Filter Monitor records the HVAC system’s
FAN OFF condition. When the blinking amber stops, this indicates proper operation.
i. However, if the unit detects air flowing in the air duct, the STATUS LED will blink red. In
this case, check to see that the system blower fan is OFF and that no condition
described in #2 above exists. If no such condition exists, start again at #1. If the error
condition persists, call 888-414-FLOW (3569) for instructions.
b. IF YOU PRESS RESET BY MISTAKE, press it again for 2 seconds until the Status LED blinks
Amber and a beep is heard.
5. Wait at least one minute before turning your HVAC system ON – The FILTERSCAN WiFi Home
Air Filter Monitor is starting the automatic calibration process during this time, calibrating itself to
the air filter and HVAC system into which it is installed.
6. To verify communication with the AFS server, you may depress the SEND button momentarily at
this point, then log into your AFS account, and select Filter Status, where you should see “OK” for
Status or Device Health.
Your FILTERSCAN WiFi Home Air Filter Monitor is now completely operational, helping protect you
from the consequences of running your HVAC system with a clogged air filter.
The SERVICE FILTER control is pre-set to mid-range. Refer to the Installation and Reference Guide.
