Installation, Care & Use Guide
Congratulations on the purchase of your new In-Sink-Erator
instant hot water dispenser. This product is designed and
manufactured to the highest standards.

practices which could result in severe personal injury or death.
The caution symbol alerts you to hazards or unsafe practices
which could result in minor personal injury or property damage.
IMPORTANT SAFETY INFORMATION!
This product dispenses water at approximately 190˚F, which
is hot enough to cause severe burns. Caution should be exercised when
installing and using this product.Do not allow children to operate this
appliance without adult supervision.
Do not attempt to install the unit until you have read and
understand these installation guide instructions.
Under no circumstances is this product to be altered in any
way other than that which is specifically addressed in these instructions.
Doing so may void your warranty.
Do not use an electric drill to drill into metal water pipes;
doing so could result in an electrical shock hazard. If necessary, use a
cordless drill or hand drill.
Premature connection of the unit to an electrical supply could
result in a “dry start” condition, which could damage the unit and void your
warranty. The unit must be completely installed and the tank must be
completely full with water running from the dispenser before plugging the
unit in to an electrical supply. Consult these installation instructions.
Do not under any circumstances use bleach, abrasive liquids,
powders or scouring pads to clean the faucet as doing so could void your war-
ranty. Occasional cleaning with a soft cloth and warm soapy water is sufficient.
A hot water dispenser, like any water heater, has limited life
and will eventually fail. To avoid possible property damage, a hot water
dispenser should be regularly examined for leakage and replaced when
necessary. A drain pan plumbed to an appropriate drain is suggested in those
applications where any leakage could cause property damage.
IMPORTANT WARRANTY INFORMATION!
Retain your receipts (purchase and/or installation) as these document the
start date of your 1-year warranty. In the absence of purchase or installation
receipts, your warranty is one full year from the date of manufacture.

WHAT YOU SHOULD KNOW BEFORE YOU BEGIN
Connecting the dispenser to your regular water supplies requires no special
plumbing. All details are covered in the installations instructions. Be sure
that the plumbing connections conform to your applicable local codes. If your
water supply contains sand, grit or other suspended particles, the use of a
filter is recommended. The filter should not result in the water pressure to
the dispenser dropping below 30 pounds per square inch (207kPa). This will
prevent your unit from operating properly.
Astandard 115-volt grounded electrical outlet is required under the sink for
the dispenser ’s electrical power. The current use is 6.5 amps only when the
tank is heating. Ensure that all electrical wiring and connections conform to
applicable codes. Note: The wall outlet to your dispenser must have
power supplied to it continuously and must be fused. It should not be
controlled by the same wall switch that operates your disposer.
