Installing the LintAlert®
Installation and calibration is a fairly quick and straight forward process.
Step One
Confirm that the in-the-wall duct system has been
completely cleaned and in like-new condition (read
Notice on reverse side).
In-O-Vate Technologies, as
well as the leading dryer manufacturers, strongly recommend using a
transition hose that is UL2158A listed, like DryerFlex™ or semi-rigid
aluminium flex. The wire bound foil flex, although not as efficient, will
work comparably with the LintAlert. If you have white vinyl flex, please
take this opportunity to replace it, as it’s been well documented to be
extremely unsafe and associated with many dryer fires.
Step Two
Disconnect the new or existing exhaust hose from where
it connects to the exhaust port on the back of the dryer.
Favoring the middle to outside radius of the flex,
carefully
poke a
¼”
hole in the hose, 4"-6" away from where the exhaust
port connects.
(Figure 1)
.
Be sure to leave room for the flex hose to
re-secure to the dryers’ exhaust terminal.
Step Three
Take the umbrella shaped tap fitting, (Figure 3 - A) and slide
it up inside the exhaust hose and through the hole you just
made. It is important to rotate the fitting so that the curved
contour of the fitting matches that of the transition hose. The felt washer
(B) will go on next, followed by the curved washer (C). Finally, twist the
nylon thumb-nut on and finger tighten to ensure that no air can escape
(Figure 4). Connect one end of the clear vinyl tubing to the tap fitting
(while supporting it from within the flex hose) and reattach the existing
exhaust hose to the dryer’s exhaust port.
Step Four
Move the dryer back into place and plug the alert module
into the nearest un-switched 110v AC power outlet
prior
to attaching the tubing to the barb
. Important Note: Cut
the length of the clear vinyl tubing to minimize any sag or droop in the
tubing, as this could allow condensation build-up within the tubing to
puddle thus creating an air block (Figure 5). Insert tubing over hose
barb on LintAlert.
Step Five [Calibration]
Clean the dryer’s lint screen. Begin a drying cycle with NO
clothes in the drum and at your usual temperature setting.
While the dryer is running, press and hold the LintAlert
button for about 6 seconds, until all five LEDs progressively light
up and you hear a chime tone (records “clean value” pressure
level).
After about 2 seconds, you should observe that the first green
LED is illuminated and the logo lens, “LintAlert,” is steady blue. Note:
Any subsequent calibration attempts will require an approximate 12
second press of the button. The LintAlert should now be in a normal
monitoring mode. Refer to the troubleshooting section of this manual
or online if this normal state is not observed.
Troubleshooting Section:
Notice:
Works on all dryers except those with booster fans, dual motor
technology and dryers that share exhaust systems like those typically found
in high-rise structures.
Tubing does not reach:
The tubing can be extended or replaced with
similar diameter tubing. We offer longer tubing lengths in our online
store, but the same tubing (1/8” ID ¼” OD) is usually available at
aquarium or pet outlets. Results with lengths up to 24 feet were shown
to be consistent. It is important that the tubing placement and type of
tubing prohibit being pinched or kinked.
No 110v outlet near my dryer:
In most cases, the washer and dryer
reside side by side, and the washer uses 110v. If the washer outlet is
hidden or too far from the dryer’s location, then the first suggestion is
to extend the tubing (see above). The second alternative would be to
purchase and mount a multi outlet power bar above the dryer for the
LintAlert to plug into.
LED Display During Calibration:
means no pressure was observed, either due to dryer not
ON, tubing not connected or LintAlert was plugged in with
tubing connected and dryer running. In the latter case,
Factory Reset (see below).
means too much pressure was present, likely the exhaust
duct was never cleaned or there still exists blockage of some
sort (e.g., inefficient vent hood).
means calibration was successful and after 2 seconds the
first LED will illuminate.
Monitoring Mode:
dryer not ON or tubing detached.

approx. 20% blocked,
approx. 32% blocked,
approx. 45% blocked,
approx. 60% blocked.
Restore to Original Calibration Level:
Unplug the unit for 3 seconds
and insert back into plug.
Factory Reset:
With dryer off, unplug LintAlert then plug back in while
pressing button and continue to hold till chime is heard (approx. 2 secs).
