To reduce the risk of burns, electrocution, fire
or injury to persons:
17. Always use the NEOREST at a room temperature of 32°F (freezing temperature) or
above to prevent frozen pipes and hoses.
●
Frozen water pipes will cause the toilet and the pipes to break resulting in water leakage.
Refer to Page 38 for instructions on how to prevent frozen pipes.
WARNING
This product should be grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for the electrical current. This product is
equipped with a cord having a grounding wire with a grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded.
Improper use of the grounding plug can result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to
either flat blade terminal. The wire insulation having an outer surface that is green with or
without yellow stripes is the grounding wire.
Check with a qualified electrician or serviceman if the grounding wire instructions are not
completely understood, or if in doubt as to whether the product is properly grounded.
This product is factory equipped with a specific electric cord and plug to permit connection to
a proper electric circuit. Make sure that the product is connected to an outlet having the same
configuration as the plug. No adapter should be used with this product. Do not modify the
plug provided - if it will not fit in the outlet, have the proper outlet installed by a qualified
electrician. If the product must be reconnected for use on a different type of electric circuit, the
reconnection should be made by qualified service personnel.
If it is necessary to use an extension cord, use only a three wire extension cord that has a
three blade grounding plug, and a three-slot receptacle that will accept the plug on the
product. Replace or repair a damaged cord.

Operational Instructions
Always follow these precautions to ensure the safe use of your product.
Do not wipe the toilet unit or seat
with a dry cloth or toilet paper.
● Use of a dry cloth or toilet paper to wipe
the toilet bowl, seat or lid will scratch the
surface.
Refer to Page 29 for instructions on how to
care for your Washlet.
Do not expose the NEOREST to
direct sunlight.
● Use of the product under direct sunlight
may result in discoloration of the plastic,
inconsistent temperature control of the
toilet seat or malfunction of the remote
controller.
Avoid getting urine on the main unit
or wand as this may result in
malfunction of the product.
Do not cover the seat sensor, motion
ditection sensor or remote control
transmitter.
● Covering the sensors or remote control
transmitter will prevent them from
working properly.
Do not lean back against the lid.
● Leaning against the lid may damage or
break it.
To avoid electrical damage to your
unit, be sure to unplug the power
cord during lightening storms.
Do not use the NEOREST near radios
and stereo equipment.
● Use of the NEOREST near a radio, etc.
will cause electrical interference.
When not in use over extended
periods of time, remove the power
plug from the wall outlet.
● However, when being used at a room
temperature of less than 32° F (below
freezing), be sure to keep the unit
plugged in to prevent freezing of the
pipes and hoses.
When restarting after extended disuse, let
water run for a few minutes before using.

Precaution concerning the Energy Saver:
●
It takes the Neorest two or three days to establish during which time periods the toilet is not used often. During
that time, the energy-saving mode will go into effect gradually.
When replacing the batteries of the remote control:
●
The energy-saving settings will disappear and must be re-entered.
When the power is switched off, or if there is a power outage:
●
The Energy Saver sometimes does not operate correctly when this happens, but it will begin operating correctly
again on the following day.
●
If the three-prong plug is unplugged when the Neorest is not used for a long time, it will operate in the same
way.

page 34.)
—
Make sure that the water shutoff valve
is open enough to allow proper flow of
water.
Wait until the water supply is restored.
—
—
Tighten the bolts with a monkey
wrench.
The toilet does not
flush properly (the
"water pressure" light
is flashing).
Is the water shutoff valve open?
Is the water supply filter dirty?
Is water being used in other areas of the
household or building? (The "water pressure"
light flashes if the water pressure is too low for
the toilet to flush properly.)
Is the water shutoff valve closed?
Has the water supply to the house been cut off?
In the following situations, the toilet seat sensor
may become activated: ● when standing in front
of the toilet seat; ● when closing/opening the
toilet seat and lid; ● when cleaning the toilet; ●
when using the toilet bowl flush lever
If the temperature inside the toilet unit is too
cold, the Washlet automatically drains itself of
water to prevent frozen pipes. When this
happens, you will hear water draining for
approximately 10 seconds, but this is not a
malfunction.
Are the bolts loose?
Water does not spray
when the toilet is
flushed.
Auto Flush (Continued)
Problem Possible Cause Solution
Move away from the toilet and wait for
3 seconds. (See page 21~22.)
Change your position on the toilet seat
or the position in which you are
standing or raise the clothing you are
wearing to allow the sensor to detect
bare skin.
Make sure that the sensors are not
covered, as this will prevent the
infrared light from projecting.
The toilet bowl flush
function does not
automatically turn on.
Is the "sensor" light on the main unit display
OFF? When it is OFF, standing in front of the
toilet will not activate the Auto Flush function.
The sensors in the toilet seat sensor and motion
detection sensor may not work properly
depending upon the way in which the user sits
on the toilet seat, or stands in front of it, or the
color of the clothing or type of fabric worn.
Is the toilet seat sensor or motion detection
sensor covered up by your clothing? Are the
sensors covered with dust or water?
The toilet flushes by
itself.
Water sprays from
the area near the
wand even though no
one is seated on the
toilet seat.
Water leaks from the
pipe fittings.
