Installation of EC-3122 ChekPoint
Faucet:

(Refer to Figures 1 and 2)

The EC-3122 ChekPoint Faucet has
above deck sensor electronics and
temperature control. Power is supplied
by four AA batteries in the top of the
faucet body. Another power option is
an AC transformer connected below the
deck to a lead wire terminal from the
bottom of the faucet.

1. Install the threaded mounting posts
into the faucet base.

2. Drill a Ø 1 ½” hole where the faucet
is to be installed (1 ½” maximum deck
thickness).

3. Guide the mounting posts, lead wire
and  exible supply hoses through the
hole.

4. Secure from beneath the deck using
the “C” washer and nuts supplied.

5. Remove the  at head VR star screw
and the cap on top of the faucet body.

6. Plug battery pack wire connector into
sensor wire connector.

7. If adjusting the Time Out and/or
Delay DIP switches, please refer to the
section below, “FEATURES AND SWITCH
SETTINGS.” Otherwise replace the cap
and  at head VR star screw.

8. If installing the AC transformer,

General Instructions

9. Connect the check valve adapters at the end of the hot and cold  exible supply
hoses to their corresponding supply stops. Turn on the supply stops and check for
leaks.

10. To test the sensor eye on/o function and switch settings (if set), place your hand
beneath the aerator. The sensor LED will blink red once.

11. Remove your hand from the area. If the water does not stop within 2 seconds
or according to the settings on SW(5) and SW(6), then the sensor range will need
adjusting (refer to “INSTRUCTIONS FOR SETTING THE SENSOR RANGE”).

LOW BATTERY DETECTION

• A red  ashing light in the electronic eye indicates low batteries.

• A solid red light in the electronic eye and no water  ow indicates the batteries

are dead.

• New batteries will need to be installed.

TRANSFORMER OPTION:

IMPORTANT: DO NOT plug the transformer into a receptacle until all wiring has been
completed. This type of transformer is designed to be plugged into a 120 VAC

wall receptacle. The transformer is supplied with a 12 foot cable. When used in
conjunction with batteries, the transformer will become the primary power source.
Plug the transformer cable into the wire lead coming from the bottom of the EC-3122
faucet body.

Note: For the Hydro Generator (EC-HYDROGEN) power option, refer to the instruction
manual in the EC-HYDROGEN kit ordered separately. For hard wiring and hard wire
ganging (EC-HARDWIRE) and easy-wire (EC-EASYWIRE) ganging power options , refer to
the instruction manual in each respective kit when ordered separately.

General Instructions

BATTERY REPLACEMENT:

When the battery is getting weak, the sensor LED will blink red. When the power is too
low to actuate the water  ow, the sensor LED will stay lit red. To replace the batteries:

1. Shut o water supply and remove the  at head VR star screw and cap from the top

of the faucet body.

2. Remove the screw and cover from the battery holder.

3. Replace the weak batteries with four (4) new AA alkaline batteries in the battery

holder by matching the + or - markings in the bottom of the holder.

4. Reinstall the battery cover. Make sure all wires are tucked in the faucet body

when reinstalling the battery cover.

5. Reinstall the cap and  at head VR star screw and turn water supply back on.

INSTRUCTIONS FOR SETTING THE SENSOR RANGE:

The EC-3122 uses a digital infrared, distance adjustable sensor which has a default
range set at the factory. Should this range need to be changed, follow the steps
below. The sensing distance is adjustable from 3/4” (2cm) to 6 11/16” (17cm).

1. Shut o the water at the hot and cold supply stops.

2. Place the magnet provided to the upper right side of the sensor lens and move it
closer to the lens.

3. Hold the magnet in place for 3 to 5 seconds. The red sensor LED will come on for
set-up mode.

4. Remove the magnet and the sensor LED will go out.

5. Place a hand to the desired sensor range, hold in place and the LED will light up.
(The recommended sensor range is 3/8” [1 cm] in front of the spout)

6. Place the magnet to the right side of the sensor lens and move it closer to the lens
until it starts blinking 5 times.

7. Remove your hand and magnet from
the sensor area.

8. Turn on the water at the hot and cold
supply stops.

9. Move a hand into the range set in
step 5 which will activate the sensor
(the LED will blink once) and water will
begin to  ow.

10. If after removing your hand from the
sensor range, the water continues to
 ow for longer than 2 seconds, then the
sensor range will need to be reset to a
shorter distance.

TROUBLESHOOTING GUIDE

PROBLEM

No Water When Activated

Red LED in electronic eye

POSSIBLE CAUSE/SOLUTION

If red LED stays on or is  ashing:

1. Replace batteries.

2. If appropriate action from no. 1 does
not correct problem, the sensor range is
too long/picking up sink; reduce range.
Otherwise sensor is faulty; contact
dealer.

Very Low Flow or Slow Dribble

False Triggering

(Unit goes on by itself)

Continues to Run

(Even after power to faucet has been
reconnected)

1. Check supply stop(s); open if closed.

2. Debris in supply hose  lter washers;
remove, clean and reinstall.

3. Debris in aerator or spray head;
remove, clean and reinstall

1. Check surroundings for factors
that can contribute to the range; for
example, bright lights, highly re ective
surfaces, sunlight, etc.

2. Range too long; decrease sensor
range.

1. Debris in solenoid valve, won’t close
properly. Contact factory.
