Intellifaucet Owner's Manual
INSTALLATION
Mechanical Connections
Connect hot water to the left side of the
Intellifaucet, and cold water to the right. Use
ball valves for shutoffs for the hot and cold
water. Install a vacuum breaker if your local
code requires it. Install water filters if your
water has sand, dirt or rust in it. Install
check valves on the inlets if connected to a
closed piping system. o not use iron or
steel pipes for water supply.
FIGURE 1. Hot on the left, cold on the
right, outlet in the center.
Electrical Connections
Connect Intellifaucet to 12V – 24V C
power source, then plug power supply in or
turn it on. Appropriate power supplies are
included with all Intellifaucets.
O tional Remote Interface (RK Models)
A 4-20mA current source and 2 momentary,
dry contact closures (relay or pushbutton) are
needed.

Symptom Cause What to Do
Valves were overtightened Loosen by hand, then close gently.
Nothing happens Power cords not connected Check cables
Fuses blown in power supply Replace fuses
Random numbers appear
Electronic component failed Have unit serviced
Valves oscillate Flow too low. Increase supply pressure or press Flow Down
Flow won't stop or start Sticky valves, mineral or rust buildup Fill faucet with mild acid then rinse
Valves do not open and make
stuttering noise after pressing
START
Power supply turned off and on too
quickly
Turn power off, wait 5 seconds, turn power
on.

OPERATION
Manual Control
Rotate knobs on top of the Intellifaucet to
open and close the hot and cold water valves.
Make sure both are gently closed before
starting automatic control. Both valves close
clockwise (looking from above).
Automatic Control
Press START to begin automatic control.
Press STOP to shut off the water. You can
change the temperature, flow or timer
settings at any time.
The flow setting is a percentage of full flow,
not an absolute value. Press START TIMER
to start water flow and activate the timer,
which will shut off the water after the preset
time.
Presets
Press and hold the “Show” keys for 3
seconds until you hear a short beep to save
the current temperature, flow or timer
settings. Press and hold F/C key for 3
seconds to change and save the F or C mode.
Jum ers
There are three jumpers on the logic board.
JP2: isable the speaker. Simply remove
shunt and put on one pin of jumper for
storage.
JP3 and JP4: Let ground float for remote 4-
20mA signals.
Remote Automatic Control
Flip the Remote/Local switch to Remote.
The Intellifaucet will now use the 4-20mA
remote signal as a temperature setpoint. The
remote start and stop lines are always active
regardless of Remote/Local switch position.
The scaling equations for the remote current
signal are:
F = 10.7 * mA – 10.75 +/- 1 F
or
mA = 0.0936 * F + 1 +/- 0.2 mA
C = 5.94 * mA – 23.75 +/- 2 C
or
mA = 0.17C + 4 +/- 0.2 mA
The standard temperature range is 32 – 203
F. The current range is 4-20mA.
Hold the remote START or remote STOP dry
contact closed for a minimum of 50 mS to
start or stop water flow. Hold both remote
START and STOP closed for idle mode.
Release both to return to control mode.
CALIBRATION
Each Intellifaucet is calibrated at the factory
and rarely needs re-calibration.
Here's how to calibrate the Intellifaucet:
irect the outlet from the Intellifaucet into a
1 quart container equipped with an accurate
thermometer. Set the Intellifaucet for 68 F,
20 to 30 percent flow and press START. Let
the temperature stabilize. Record the actual
temperature. Repeat at 102 F. Press STOP.
To enter calibration mode, press and hold the
STOP key for 3 seconds until you hear a
short beep and the letters CAL appear on the
display. The Zero offset is set with the
FLOW keys, and the Gain is set with the
TIMER keys.
IMPORTANT: When finished calibrating,
press STOP for 3 seconds until you hear a
beep to save the calibration values and return
to normal mode.
There are 4 possible cases:
1. There is no error. Unit is calibrated.
2. Both errors are the same. Press the FLOW
keys (offset) to raise or lower the
temperature.
3. The error at the high temperature is more
positive than the error at the low
temperature. Press the TIMER (gain) key
down.
4. The error at the low temperature is more
positive. Press the TIMER key up.
Repeat as necessary.
MAINTENANCE AND REPAIR
Most problems can be solved by cleaning all
of the internal parts with a mild acid
solution. An easy way to do this is to
uninstall the unit, plug the inlets, lay the unit
on it's back in a sink or tray, and pour the
mild acid into the outlet. Let sit for a few
hours, rinse and reinstall. isassemble the
unit and manually clean all the parts if
needed.
To disassemble the Intellifaucet, remove
parts top down, and assemble bottom up.
