Before You Begin
WARNING: Risk of electric shock. Connect only to a circuit protected by a
Class A Ground-Fault Circuit-Interrupter (GFCI)*, which protects against line-
to-ground shock hazard. Use 120 V, 60 Hz, 15 A service.
WARNING: Risk of electric shock. Do not immerse or ush the product with
water.
CAUTION: Risk of product damage. Do not install this product in a location
exposed to excessive moisture where condensation might form on the product
surface. Provide adequate ventilation when bathing to avoid damage to the
electronic components due to high humidity levels.
CAUTION: Risk of product damage. Do not supply electrical power to the
unit until the plumbing installation work has been completed, as it may cause
the product to malfunction.
CAUTION: Risk of property or product damage. Pushing or pulling on the
water connection may cause water leakage.
NOTE: The thermal protectors may trip during storage or transportation in warm
weather causing the unit to not operate. Allow the unit to cool to room temperature
before installation or operation.
Follow all local plumbing and electrical codes.
Connect the seat to a cold water supply of drinking quality with a pressure of 20 psi
(139 kPa) - 80 psi (551 kPa).

WARNING: Risk of electric shock. Connect only to a circuit protected by a
Class A Ground-Fault Circuit-Interrupter (GFCI)*, which protects against line-
to-ground shock hazard. Use 120 V, 60 Hz, 15 A service.
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 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.
DANGER: Risk of electric shock. 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 at 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 qualied electrician or service personnel if the grounding instructions
are not completely understood, or if in doubt whether the product is properly
grounded.

CAUTION: Risk of property damage. A single extension cord may be used
provided that the cord “Type” begins with “SJ”, the cord is a 12 gauge,
grounded (12/3), is no longer than 25 feet (7.6 meters), and is plugged into a
GFCI* electrical outlet. Promptly replace any extension cord that exhibits any
sign of damage.
*Outside North America, this may be known as a Residual Current Device (RCD).
NOTICE: Follow local codes when determining the connection type. The temporary
connection may not be permied by local electrical codes.
NOTICE: To avoid possible product malfunction, do not plug in the seat until
instructed.
Preferred Connection
Connect the grounding plug into a grounded outlet that has the same conguration
as the plug.
Temporary Connection
NOTICE: Unless the outlet cover screw is grounded through the house wiring,
aaching the adapter grounding screw tab to the cover screw will NOT ground the
unit. If there is any doubt whether the cover screw is grounded, have it checked by a
qualied electrician or service professional.
A temporary connection with a two-prong adapter may be used where local codes
permit, provided the adapter is grounded.
