Danger

• Do not place or store the Washlet in a place where it can fall or be pulled into a tub or
sink.

• Do not place the Washlet in water or other liquid.

• Do not reach for the Washlet if it has fallen into water. If it falls into water, unplug it

immediately.

• Possible electric shock. Avoid any water or cleaning agent contact (or splashing) with
electric outlet, power cord or main unit.

• Do not use stagnant water in the main unit. The main unit water tank should be cleaned
or emptied if water has been left in the tank for at least 14 days without use. There may
be a risk of unhealthy bacteria levels in water that sits stagnant for this period of time.

• If any part of the Washlet becomes damaged and internal wires are exposed, unplug
and do not use the Washlet. Return the Washlet to an authorized TOTO USA, Inc.
dealer for repair or replacement.

• Do not use a toilet cleaning agent, detergent, benzine, thinner, cleanser, or a nylon
scrub brush to clean the Washlet as it may damage the plastic. (The plastic may crack
or peel, leading to exposed wires or product instability.)

• Possible mild burning.
When using the seat heater, mild burning may occur. Be attentive to others (listed
below) by turning off the seat heater (see page 18). Leave the seat heater off except
when a person capable of properly operating the Washlet C100 is using the product.

• Those who cannot control the seat temperature appropriately such as small children and some

elderly persons.

• Those who have limitations in body movement or sensation such as ill or disabled persons.

• Those who might fall asleep due to alcohol consumption, lack of sleep, or medication that

causes drowsiness.

• If you stay on the seat for more than 15 minutes, turn off the seat heater.

Ignoring the instructions in this display
may cause death or serious injury.

✲ About Low Temperature Burns

A burn gradually occurs when the skin has been exposed to high temperatures.
However, a low temperature burn may occur when the skin has been in contact with an
object at relatively low temperature (about 104°F). Susceptibility to burns also depends
on an individual’s skin sensitivity and other factors.
The temperature is set at the factory to about 97°F (36°C). At this temperature, no low
temperature burn should occur for individuals with normal skin and skin sensitivity.
However, if any burning sensation, discomfort, or rash occurs, immediately turn off the
seat heater and consult a doctor.

• Do not place the Washlet in a room where the humidity exceeds 90% Rh. (It may
cause fire or electric shock.)

• Do not install the Washlet in a location where water may be splashed or where
excessive moisture can condense and form on the product surfaces.

• To avoid damage to electronic components due to high levels of humidity, provide
adequate ventilation by opening a window and/or door when bathing. Operating an
exhaust ventilating fan during times of high humidity will be beneficial.

Important Safeguards (continued)

General

prohibitions

Danger

Improper use of the grounding plug can
result in a risk of electric shock.

GROUNDING INSTRUCTIONS

• 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 electric current. This washlet is equipped with a cord having a
grounding wire with a ground plug. The plug must be plugged into an
outlet that is properly installed and grounded.

• If repair or replacement of the cord or plug is necessary, do not connect
the grounding wire to either flat blade terminal. The wire with 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
instructions are not completely understood, or if in doubt as to whether the
product is properly grounded.

• This product is for use on a nominal 120 volt circuit and has a grounding
plug that looks like the plug illustrated in Figure A. 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.

Getting

Started

Grounding Pin

Figure A

• The electrical outlet must be a 120 volt, 60 Hz and at least a 15 Amp
GROUNDED OUTLET, should be located on the wall within reach of
the washlet power cord.

• This washlet must be on a separate circuit. No other appliance should
share the circuit with this Washlet. Sharing a circuit could cause the
branch circuit fuse to blow or the circuit breaker to trip. Continuous
usage under these conditions could result in a fire.

• A ground fault circuit interrupter (GFCI) should be installed on the
circuit supplying power to the Washlet.

Installing the Washlet C100

This section explains how to install the Washlet. Follow the instructions and install the Washlet correctly. If
you have any problems installing the Washlet, contact the store where you purchased your Washlet. For
product information, contact TOTO customer Service at 1-888-295-8134.

Be sure to follow the Warnings and the Precautions on pages 2 through 5.

Precautions Before Installing the Washlet

INSTALLATION PRECAUTIONS

It has been our experience that local building codes in the United States provide for
the power and water pressure to be within the ranges set forth below. However, you
should consult with your local authorities, and with the proper electricians and
plumbers, to be sure.

• Use an AC 120V (60 Hz) power source. The maximum power consumption is
570 W. Be sure to use suitable wiring for these requirements.

• The length of the power cord installed in the product is about 3 feet (1 meter).
The GFCI power outlet you plan to use should be located within 2 feet (0.6 meter)
of the Washlet’s Operation Panel.

• Do not use direct current (DC) or 240V AC power supply.
(It may cause a fire, leak, and/or malfunction).

• The water pressure of the water supply should be between 20 p.s.i. and 80 p.s.i.
Adjust the water pressure so that it is within this range.

• The water temperature of the water supply should be between 32°F and 95°F
(0° to 35°C). Adjust the water temperature so that it is within this range.

• The length of the connection hose supplied with the product is about 20 inches
(0.51 meter) in length. The junction valve should be installed within about 20
inches (0.51 meter) of the water supply inlet of the Washlet’s main body.

• The electric power should be connected, and the water supply opened, to the
Washlet only after installation is fully complete.

• Only mount the SW824 (Elongated type) Washlet on toilets with elongated
bowls, and only mount the SW823 (Round type) Washlet on toilets with round
bowls. Mounting the Washlet on the wrong type of toilet may cause undue stress
on the base plate and bolts with continued use, causing structural instability to
the Washlet and possible serious personal injury.

• When using a radio, move the radio away from the Washlet. (The radio may pick
up noise.)

Mounting the Washlet on the Toilet Bowl

Warning

• Mounting your Washlet on
the wrong type of toilet may
cause undue stress on the
base plate and bolts,
causing structural instability
to the Washlet and possible
serious injury.

Caution

• If you do not hear a click in
step 9, repeat this step until
you do hear a click.
Attempting to force the
Washlet into position may
damage or break the
Washlet. The Washlet
should mount with minimal
effort. To test the proper
mounting of the Washlet,
gently pull the unit in the
opposite direction of the
arrows shown in step 9. A
properly mounted Washlet
should not slide away from
the base plate. Do not
attempt to apply more than
minimal force.

• Do not overtighten the
bolts. Excess tightening
may damage the bolts, the
base plate, the toilet or the
rubber gasket. You should
tighten the bolts only
enough to hold the base
plate firmly in position.

9 Mount the Washlet by aligning the grooves underneath the

main body with the grooves on the base plate and sliding
the main body onto the base plate until it clicks.

Make sure the Washlet can be mounted smoothly and correctly without
excess stress or distortion.

toilet bowl.

13 Mount the Washlet (see step 9).

After you mount the Washlet on the toilet, you should be able to
move the Washlet slightly up and down and side to side. This is
normal. There is a small gap between grooves in the main unit
and base plate to allow easy and smooth mounting.
