Faucet operates on and off “by it self”:
1. Sensor range adjusted too long, and must be adjusted for shorter range.
2. Objects (such as sink lip) may be present in close proximity to sensor.
3. (Rare) Severe transient infrared signal present in the environment, probably caused by a defective neon light.
Faucet leaks, drips:
Constant leaks or drips indicate defective solenoid valve, send Faucet Automator for repair or contact an authorized plumbing
professional.
Loud thump noise when faucet turns on and off.
This is an issue commonly associated with diaphragm type valves such as washing machine valves, dishwasher valves, etc. The
noise is generally present in the piping system. Clear winner remedies are to:
1. Lower water flow rate (see flow rate adjustment section of this manual).
2. Install “hammer arrestors” in close proximity to your automatic faucet. Please consult a plumbing professional for this task.
3.
Problem often caused by defective angle stop. Replace angle stop.
Faucet continues to run for 30 or 60 seconds after hands are removes then shuts off:
This very rare condition generally occurs due to over sensitivity on the part of the sensor, high water flow, and/or bathroom lighting
setting. This condition is always field curable.
1. Turn down water flow rate.
2. Replace aerator with 0.5GPM aerator (when possible).
3. Adjust sensor range to “shorter”. Please call MAC Faucets for instructions.
Runaway faucet, water runs out of faucet continuously, longer than 1 minute, does not stop.
1. Make sure batteries are installed properly, if A.C., make sure that power is present at wall receptacle.
2. Make sure Faucet Automator is properly oriented on the wall, see drawings below.
3. Make sure that sensor wire from faucet is plugged into Faucet Automator.
4. Make sure that sensor wire is not cut or broken specially near mounting nut and washer immediately below deck.
5. Make sure that water is plumbed correctly into Faucet Automator, Water in to “inlet”, water out from “Outlet” see Drawings.
6. If items 1 to 5 are OK, please contact Factory for more tips on your particular installation.
Special Installation Note
Automatic faucets are design to perform properly in a variety of applications. There are some conditions,
however, that may adversely impact the faucet’s ability to perform. Please note the following conditions prior to
installing you new faucet:
1. Your automatic faucet is designed for indoor applications. This faucet is not designed for outdoor
applications.
2. Avoid installing your new faucet in direct sunlight. Direct sunlight that is focused on sensor will
temporarily disable faucet’s sensing capabilities.
3. If you choose to install your faucet to one water source only,
do not install to hot water only
as this
may result in scalding injury.
4.
Important:
Before connecting supply line to Faucet Automator, purge both hot and cold water lines for
at least one minute each at high volume. Purging water lines clears out dirt and debris that would
otherwise find its way to screen filter within the solenoid valve.
5.
Important:
Do not use pipe putty on water connection to faucet. Pipe putty may cause immediate and
irreversible damage to solenoid valve. Please use Teflon tape instead.
6.
Important
: If you do not plan on using faucet immediately after installation (within 60 days of
installation), disconnect water supply lines to faucet and unload the water pressure that may be present in
faucet. This will keep new solenoid valve components from bonding together under high pressure.
