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.
