Equipment You May Need:

We are delighted that you have chosen the InSinkErator®Instant Hot Water Dispenser to be a part of
your home. This unique appliance will save you time and effort in the kitchen, and you’ll enjoy
discovering new uses for it each day. That’s exactly why millions of people are now using an
InSinkErator Instant Hot Water Dispenser.

We are confident that by following our step-by-step instructions, you’ll soon be enjoying the
convenience of instant hot water.

 For your satisfaction and safety, read all instructions,cautions, warnings and dangers before installing or using this

instant hot water dispenser.

 This particular unit is not intended for commercial use.
 Make sure that all electrical wiring and connections conform to local codes.
 A standard 120-volt grounded electrical outlet is required under the sink for the dispenser’s electrical power.
 The wall outlet powering your dispenser must have power supplied to it continuously.
 This outlet must be fused and should not be controlled by the same wall switch that operates the disposer, unless you

have a SinkTop Switch™from InSinkErator®.

 It is recommended that a dedicated control valve be installed on the cold water line supplying water to this system.
 If you suspect elevated levels of chlorine in your water, or your water has a rusty appearance before the installation

of this unit, it is recommended to use our water filtration system.
This product contains stainless steel. The manufacturer cannot guarantee against rusty water because of the

number of factors that are involved beyond the manufacturer’s control. However, the sudden appearance of rusty
water discharged from the hot water dispenser may indicate the need for service or replacement of this product.

 The use of a water filter should NOT result in the water pressure to drop below 30 psi (207kPa).

If it does, this will prevent your unit from operating properly.

 Moving parts inside the tank causing a rattling noise is normal.

WHAT YOU SHOULD KNOW BEFORE YOU BEGIN

Equipment Required:

Dispenser: 3-year warranty
Stainless Steel Tank: 3-year warranty

Covers all replacement parts and labor to correct defects in material or workmanship in the
dispenser system, excluding the replaceable filter cartridge, for the full warranty period from the
date of installation in your home. If warranty service is required during the warranty period,
contact an authorized InSinkErator service agent to replace or repair the unit in your home at no

receipt may be required to verify warranty status. When service is required, and for the location
of your nearest factory authorized service center, call toll free 1-800-558-5700.

The foregoing warranty does not apply to damage or inoperation resulting from accident,
alteration, misuse, abuse, improper installation, installation not in accordance with these

exclusion or limitations of incidental or consequential damages, so the above limitations or
exclusion may not apply to you. This warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.

This appliance must be grounded. This instant hot water dispenser is equipped with a cord that
has a grounding conductor and a grounding pin. The plug must be connected to an appropriate
outlet that is properly installed and grounded in accordance with all local codes and ordinances.

installed by a qualified electrician. Check with a qualified electrician or serviceman if you are in
doubt as to whether the instant hot water dispenser is properly grounded.

WARRANTY INFORMATION

Fire Hazard: To minimize possibility of fire, DO NOT store flammable items such as
rags, paper or aerosol cans near the tank. DO NOT store or use gasoline or other
flammable vapors and liquids in the vicinity of this or any other appliance.

An instant hot water dispenser, like any water heater, has a limited life and will eventually fail.
To avoid possible property damage and personal injury, this instant hot water dispenser
should be regularly examined for leakage and/or corrosion and replaced when necessary. A
drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used
in those applications where any leakage could cause property damage. To check for
corrosion, examine the appearance of the dispensed water in a clear glass once every three
(3) months. If there is any discoloration or rusty appearance, unplug and drain unit as
described in the Seasonal Storage/Drainage section on page 12 of this manual. If the water
discoloration remains after draining and refilling unit, discontinue use and contact an
authorized InSinkErator service agent.

Scalding Hazard: The faucet dispenses near-boiling

(212ºF) water which can instantly cause scalds or

burns. Use care when operating this appliance.
