Getting Started
Use a thermometer or similar method to check
water temperature before using. Water temp
should not exceed 140° F (60° C) or scalding
may occur.

Do Not
Caution
Do not allow the product to freeze or become
wet. Do not install outdoors. Property damage
may result.
Warranty does not cover damage to the
product due to freezing.
Do not allow any part of the product to be
dropped or forcefully struck. The operation of
the product may be affected resulting in fire,
electrical shock, or property damage.
Always use fresh batteries in unit. Do not mix
new and old batteries or use batteries of
different brands together. Damage to the
product may result from battery leakage.
Do not install product on a weak or easily
damaged surface. Improperly secured items
may damage may damage surfaces if they
come loose. Installation on wallpaper or similar
wall treatments may result in tearing.
Once the adhesive film has been used it
cannot be removed and reused. Use a new
piece after cleaning surface.
If the product will not be used for an extended
period of time (such as during a vacation),
please turn off the faucet directly to ensure that
water will not be wasted and that property
damage will not occur.
Compulsory
Do not install the remote control where it can
be tripped over. It is most commonly installed
on the toe plate just under the cabinet.
If the remote control is installed on a plastic
vinyl chloride surface, use the adhesive base
strips to secure it in place.
In order not to damage the floor or cabinet
surface while replacing the batteries in the
remote control, use gentle pressure and move
slowly to remove it.

Battery
Firm! Tight!
It is important to check for leaks and loose pipe
connections at least once every two years.
Repair any leaks and tighten any loose fittings,
or property damage may occur.
Keep the batteries in a safe place, beyond the
reach of children. If ingested, contact a
physician immediately.
Before cleaning the filter, make sure the hot
water valve is closed and the solenoid valve
has cooled. Otherwise scalding may occur.
Close
Open
It is suggested that, after using the hot water,
the faucet should be returned to cold before
turning off. This is to prevent the next person
from scalding themselves on hot water left in
the pipes.

Check that the cords of the solenoid
valves are firmly connected to the
controller.
Make sure that none of the cords touch
the hot side solenoid valve or any metal
that is heated. Cords may melt and cause
product to malfunction

Be Careful
Do not install the remote control or the controller on a metal
surface, such as stainless steel. Product may malfunction if the
signal is reflected or hindered. Likewise, it may not do well in a
kitchen with numerous stainless steel appliances.
Do not cover the remote control or the controller with metal such
as aluminum foil. Metal will reflect the signal, causing the product
to malfunction.
Test the signal before you decide upon a permanent location for
the product. Make sure it will work properly. The remote control
should be within 3 feet (1 meter) of the controller.
Make sure the remote control is secure and in a safe place before
using. If it falls or is kicked, it may be damaged. It should not be
installed where it might become a trip hazard.
If the remote control is to be installed on a plastic vinyl chloride
surface, use the adhesive strips as a base to secure it. This
should prevent discoloration of the surrounding material. The
bottom of the next page has a diagram showing the placement of
the strips.
Do not install the remote control in front of any air vents or
heaters.
Do not use near an electric converter or transformer. It may
malfunction.
Close proximity to a TV or radio may cause this product to
malfunction.

Information
Tap once
Tap again
Tap a third time
If the battery is dead, there is
a chance that the valve will
respond if the remote is
tapped three times.
The remote control uses one CR2032 lithium battery.
It is recommended that you replace the battery in the remote control
unit at least once a year. If, however, the remote control is being used
excessively, the battery may need to be changed more frequently.
It is recommended that you replace the
battery before it dies in order to continue
using the product uninterrupted.
If the battery dies, the solenoid valve will
remain as it is - closed or open, as the
case may be. In either case, the water
should be turned off manually with the
faucet handle.
The battery that normally ships with this product has been used to test
the product. It may or may not last a full year. It is recommended that it
be replaced with a fresh battery before it dies. Batteries are not covered
under warranty.

Dust may reduce the adhesive force, so it
should be cleared off.
Do not clean the remote control directly with
water.
The remote control uses 4 “AA” Alkaline Batteries.
It is recommended that you replace the batteries in the controller at least
once a year. If, however, the controller is being used excessively, the
batteries may need to be changed more frequently.
If the battery is dead there is a
chance that the valve will
respond if the remote is

This operation will open the cold-side
solenoid valve, so that cold water will flow
out. While there is no battery power you
may continue to use the faucet by turning it
off and on with its handle. After the
batteries are replaced, the faucet will
return to normal operation.
Push the manual switch under
the controller.
The manual switch must be pushed within 90
minutes of the power failure. Otherwise you will
have to wait until the batteries are replaced.
When there is no battery power, the remote
control cannot be used.
In this period, only cold water can be used.
This operation will open the cold/hot-side
solenoid valve and water will flow out. Push
it again to stop the water flow. After the
solenoid valves are open, you can use the
faucet as a regular manually operated one.
For information on how to replace the
remote control battery, please refer to pg. 15
