IMPORTANT: The smart module needs a strong signal from your WiFi router to work properly.
Test the strength of your WiFi network’s signal where you plan to mount the smart module—make
sure your phone is on the WiFi network you want to use, then look at the WiFi signal meter on your
phone’s screen. Make sure you’re getting at least 50% signal strength where you plan to install. If not,
try moving your WiFi router closer (or installing a WiFi signal booster close to the installation).

E. Screw the hoses onto each automatic shut-off valve
Make sure each laundry hose still has its o-ring inside the hose tting. If it
doesn’t, use one of the extra o-rings provided in this package (if it already has
one, don’t add another).
Make sure to match each hose to the shut-off valve it was on before. Then screw
each hose on tight by hand (use a channel lock or pliers for the last quarterturn).
3. Screw each hose tting onto the
automatic shut-off valves.
Hand-tighten the collar of the
tting onto the washer shut-off
valve. Keep the valve at a 4 o’clock
position until you’re ready to give
the nal tightening, then turn the
entire valve assembly to tighten
and straighten.
