IMPORTANT SAFEGUARDS
READ ALL INSTRUCTIONS BEFORE USING
When using electrical products, especially when children are present, basic safety precautions should
always be followed, including the following:
DANGER: Risk of electric shock. Connect only to a circuit protected by a Ground-Fault
Circuit-Interrupter (GFCI)*.
WARNING: Risk of electric shock. Disconnect power before servicing.
*Outside North America, this device may be known as a Residual Current Device (RCD).
WARNING: To reduce the risk of burns, electrocution, fire, or injury to persons:
Close supervision is necessary when this product is used by or near children, the elderly, or
invalids. Adjust the temperature of the seat for the elderly, those who are incapacitated, or persons
with sensitive skin.
Use this product only for its intended use as described in this manual. Do not use attachments not
recommended by Kohler Co.
Never operate this product if it has a damaged cord or plug, if it is not working properly, if it has
been dropped, damaged, or dropped into water. Return the product for examination and repair.
Keep the cord away from heated surfaces.
Never block the air openings of the product. Keep the air openings free of lint, hair, and the like.
Never use while sleeping or drowsy.
Never drop or insert any object into any opening or hose.

Connect this product to a properly grounded outlet only. See the ″Grounding instructions″section.
SAVE THESE INSTRUCTIONS
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 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
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 service personnel if the grounding instructions are not
completely understood, or if in doubt whether the product is properly grounded.
Do not use an extension cord with this product.
