Installation Considerations

• For best results, Hansgrohe recommends that this unit be
installed by a licensed, professional plumber.
• Please read over these instructions thoroughly before
beginning installation. Make sure that you have all tools
and supplies needed to complete the installation.
• Keep this booklet and the receipt (or other proof of date
and place of purchase) for this product in a safe place.
The receipt is required should it be necessary to request
warranty parts.
• Flush the hot and cold supplies thoroughly before installing
the faucet. Damage to the faucet caused by debris is not
covered under the warranty.
• The hot and cold supplies should be of equal pressure.
• The faucet should not be used with a continuous flow water
heater.
• Do not install the faucet on a sink with a raised edge.
• Strong light sources should not shine directly on the sensor
window of the faucet.
• The faucet should only be used with the battery pack
supplied by Hansgrohe. Do not attempt to use any other
battery pack.
• The faucet incorporates automatic range adjustment --
the sensor automatically adjusts itself to local conditions
(lavatory, brightness, etc.)

Please know and follow all applicable local plumbing
codes when setting the temperature on the water heater.
** 10 second maximum cycle time
*** This is the maximum amount of time the faucet will run
while a hand is within range of the sensor.
• The distance between the switch on/off point to the faucet
is approx. 6¼" - 8" under normal conditions. The detection
area may be less for dark, non-reflective objects, or greater
for bright, highly reflective objects.
If the sink is very small or highly reflective,
follow the range reduction instructions. When
the faucet is in reduced range mode, the LED in the
sensor window will flash while the faucet is not in use.
• Drops of water or condensation on the sensor window
may cause the faucet to run.
The spray pattern will be unattractive
immediately after installation or service, due
to air in the faucet. After the faucet is used 10
- 15 times, the spray pattern will clear.
• At the start of operation, or after maintenance, function
of the faucet may be delayed due to reflections during
adjustment of the operating distance. The faucet will
automatically calibrate itself. The self-calibration will start
after 10-15 minutes.
Hansgrohe recommends not to use as drinking water
the first half liter (approximately 1 pint) flowing from
the faucet in the morning, or after prolonged non-use.
