1. Location
Do not install the Push-button HWR-D in
a shower or under the tap/faucet where
it could be exposed to water. Mount it at
a suitable height out of reach of small
children and pets.
Maximum ambient temperature is
104 °F (40 °C), non-condensing
environments.
2. Installing the push-button
To install the push-button:
1. Remove the mounting bracket from
the back of the push-button.
2. Remove the pull-tab from the end
of the AAA batteries. The push-button
will start up.
3. To pair the push-button with the
pump: With the push-button near the
pump, press and hold the connect
button on the pump for 2 seconds.
The blue connect symbol will ash.
The connect symbol will stop ashing
after 30 seconds if no device has been
detected.
4. Activate the push-button for 2
seconds. The blue connect symbol on
the push-button will ash.
5. After successful pairing of the push-
button and the pump, the blue connect
symbol will be on continuously for 5
seconds on both devices.
6. If the pairing fails, the connect symbol
will ash red for 5 seconds on both the
pump and the push-button. If pairing
fails, retry the pairing procedure.
7. To verify operation activate the push-
button for less than 2 seconds. Check
that the connect symbol on the pump is
on and green for approx. 2 seconds and
the pump turns on.
8. Use the included double-sided tape
to fasten the mounting bracket to a
surface or wall away from water droplets
or splashes.
9. Snap the push-button onto the
mounting bracket.
10. If more than one push-button is
