Step 1 – Remove all mounting hardware
Shut off water supply and remove the hexagonal
nut, the disk and the gasket. Do not remove the
O-ring from the base of the faucet.
Step 2 – Installing the faucet
1. Place the faucet with O-ring into the hole in
deck or lavatory. Make sure the O-ring is located
between the deck or lavatory and the bottom of
the faucet.
2. Slide the gasket over the flexible hose.
3. Secure the faucet to the deck or lavatory with the hexagonal nut and the disk.
Step 3 – Connecting the water supply
1. a. For Green Time, Green Time B, Green Time E: Connect the flexible pipe to the
water supply.
b. For Green Time 1000, Green Time 1000 B, Green Time 1000 E: Connect the red
flexible pipe to the hot water supply and the blue pipe to the cold water supply.
2. Make sure that the filter/s is/are installed between the flexible pipe and the shut
off valve (not supplied).
Step 4 - Connecting the power source
1. Connect the power source:
a. For Green time B or Green Time 1000 B: install the battery box at the wall
underneath the sink using the two sided adhesive foam facet. The cable
connection must point down. (You can use an optional extension cable in order to
assemble the battery box up to 10ft. away from the sink.)
b. For Green Time E or Green Time 1000 E: Plug the transformer into the electricity
socket and connect the connectors.
Important: In order to avoid entering into the adjusting mode, wait 10 seconds before
you will operate the system.
2. Turn on the central water supply and the shut-off valve/s.
3. Check for leaks.

Adjustment levels
The flow time is programmable on site. If necessary, the default flow time of 8
seconds can be adjusted to any value between 1 to 60 seconds. The Green Time
adjustment mechanism is composed of 3 adjustment levels for changing the flow
time. An indicator light (LED) will guide you from one level to the other.
The following table shows the number of steps in each level, the duration of each
step and how to recognize in what adjusting level you are.
The following examples show how to manage the adjustment levels:
Example 1: You wish to adjust the flow time to 20 seconds.
At level 1 perform 3 steps of 1 second (you will get 3 seconds). Total: 3 seconds
Go to level 2 and perform 1 step of 2 seconds (you will get 2 seconds). Total: 5
seconds)
Go to level 3 and perform 1 step of 15 seconds (you will get 15 seconds). Total: 20
seconds.
Example 2: You wish to adjust the flow time to 45 seconds.
At level 1 perform 1 step of 1 second (you will get 1 second). Total: 1 second
Go to level 2 and perform 7 steps of 2 seconds (you will get 14 seconds). Total: 15
seconds)
Go to level 3 and perform 2 steps of 15 seconds (you will get 30 seconds). Total: 45
seconds.
Example 3: You wish to adjust the flow time to 60 seconds.
At level 1 perform 10 steps of 1 second (you will get 10 seconds). Total: 10 seconds
Go to level 2 and perform 10 steps of 2 seconds (you will get 20 seconds). Total: 30
seconds)
Go to level 3 and perform 2 steps of 15 seconds (you will get 30 seconds). Total: 60
seconds.

Level 1 Level 2 Level 3 Out of adjusting mode
How to adjust the flow time at Green Time
1) Open the piezo cup using the provided 2 mm
Allen key.
2) Disconnect the internal battery.
3) Touch the piezo cap twice.
4) Then, reconnect the battery.
5) The indicator light (LED) on the back of the
Piezo cap will start blinking. After a few blinks
the LED will give a steady red light. Touch the
Piezo cap when the steady red light is still on
to enter into the adjusting mode. When done
correctly, the light will stop blinking.
Note: If you will not press at the indicated area, the previous adjustment will remain.
6) By touching the Piezo cap the new flow time will be programmed. In adjusting
mode level 1, each touch increases the flow time by 1 second with a maximum of
10 seconds. You will see the LED blinking every time that a new step is performed.
7) If your desired flow time is within 10 seconds, no other adjusting levels are needed
and you can stop pressing the Piezo cap. The LED will blink 2 times, then 3 times
and after 4 times you will leave the adjusting
mode. The Green Time is now adjusted to the
desired flow time.
8) If you need to perform steps at adjusting
level 2, wait after you see the LED blink
twice and then, perform the needed quantity
of steps (with a maximum of 10 steps of 2
seconds).
If you do not need more levels, stop pressing.
The indicator light will blink 3 times and after
4 times you will leave the adjusting mode. The
Green Time is now adjusted to the desired
flow time.
9) If you need to perform steps at adjusting
level 3, wait after you see the LED blink 3 times and then, perform the needed quantity
of steps (with a maximum of 2 steps of 15 seconds).
10) To leave the adjusting mode wait until the LED blinks 4 times. The Green Time is
adjusted to the desired flow time.

The Green Time faucet has an advanced battery level management system consisting
of two steps:
Step 1
The battery still has enough power to open and close the solenoid valve.
At this first step the battery level management system allows the solenoid valve to
open and close but will activate a warning indicator light.
The LED at the back of the Green Time cap will blink twice when the battery level
management system has activated step 1 and the user touches the designated area.
Step 2
At his point the battery might not have enough power to open and close the solenoid
valve.
The battery level management system does not allow the solenoid valve to open.
Instead of providing an opening and closing pulse, the system provides two closing
pulses.
The LED at the back of the Green Time cap will blink three times when the battery
level management system has activated step 2 and the user touches the designated
area. Water will not flow since the solenoid will not be opened.

BaTTERY REPlacEMENT
To replace the battery in Green Time:
1) Turn off the shut off valve.
2) Remove the faucet cover with the supplied Allen key.
3) Release the screw and remove the cover.
4) Disconnect the connector coming from the faucet cover to the battery.
5) Replace the used battery with a new 9V battery. A Lithium battery is
recommended.
6) Carefully place the new battery inside the body and reassemble the faucet cover
to the battery.
7) In order to avoid entering into the adjusting mode, wait 10 seconds before you
will operate the system.
Important:
- Since water contacting the battery terminals rapidly drains the battery, do not
allow moisture or water into the system while the battery is being replaced.
- Make sure the O-ring is still in its groove and is not damaged. If needed
replace it with a new one if needed or clean and lubricate it with silicon grease
before reassembling the parts.
To replace the battery in Green Time B, Green Time 1000 B:
1. Carefully open the battery box.
2. Remove the old battery.
3. Replace the used battery with a new 9V battery. A Lithium battery is recommended.
4. Close the box.
5. In order to avoid entering into the adjusting mode, wait 10 seconds before you will
operate the system.

Filter cleaning instructions
This faucet is provided with one or two stainless steel filter/s preventing foreign
particles to enter the lines. If the water flow has decreased, this may be because
the filter is clogged. The filter can be cleaned as follows:
1. Shut-off the water shut off valve.
2. Disconnect the flexible pipe.
3. Remove the filter/s and wash it/them under running water.
4. Reassemble the parts.
5. Reconnect the flexible pipe and restore the incoming water supply.
6. Make sure that there is no water leakage.
Care and cleaning of chrome and special finishes
DO NOT use steel wool or cleansing agents containing alcohol, acid, abrasives, or
the like. Use of any prohibited cleaning or maintenance products or substances
could damage the surface of the faucet. For surface cleaning of faucets use ONLY
soap and water, then wipe dry with clean cloth or towel. When cleaning bathroom
tile, the faucets should be protected from any splattering of harsh cleansers.
