Safety Precautions (Continued)
CAUTION
Do not pour hot water into the toilet.
 Doing so may result in damage to the toilet, injury or water damage.
Do not flush anything other than bodily waste and toilet paper. Also, do not
flush too much toilet paper.
 Doing so may clog the toilet, causing waste water overflow and water damage.
Do not look directly at UV Light.
 May cause eye or skin irritation.
 There are no user replaceable parts. Shall be serviced by qualified personnel only.
If a water leak should occur, always close the shutoff valve.
When the ambient temperature is likely to drop to 0°C (32°F) or lower,
prevent damage to the pipes and hoses due to freezing.
 Frozen water pipes could cause the top unit and the pipes to break, resulting in a water leak.

Regulate the room temperature to prevent the pipes and hoses from freezing during cold months.
When not using the NEOREST over an extended period of time, drain the
water out of the top unit and the water supply hose after closing the water
shutoff valve, and pull the power plug from the outlet.
When using the product again, allow the product to refill with water first.

When installing the water filter drain valve, make sure that it is securely
tightened in its proper position.
 Failure to securely tighten it may cause a water leak.
If the bowl unit is clogged, disconnect the power plug and remove the clog.
 If the auto flush were allowed to function, it would make the wastewater in the bowl unit overflow
and may result in water damage.

Use commercially available tools that are made for unclogging the bowl unit to remove the clogging.
Always flush, even after just urinating.
 Failure to do so may cause inadequate flushing or clogging of the bowl unit, resulting in waste
water overflow and water damage.

Safety Precautions (Continued)
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 electrical
current.
The plug must be plugged into an outlet that is properly installed and grounded.
DANGER - 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-head terminal.
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 outlet that will accept
the plug on the product.
Replace or repair a damaged cord.
