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, it is recommended to use our water
filtration system.
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:
Drill
T-fitting
Dedicated control valve
Adjustable wrench
Phillips and flat blade screwdrivers
Pencil
Tape measure
Level
Anchors for drywall

If you intend to use the sprayer hole in your sink for your dispenser, you may need a basin wrench and a
1/8" plug or a 1/4" cap (not supplied) for the faucet spray hose line.
See Step 1-B.
If you need to cut a mounting hole in your stainless steel sink, you may need a 11⁄4" - 11⁄2" hole saw made
for cutting stainless steel or a hole punch. Consult a professional if you are drilling into a surface other
than stainless steel.

installation 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.
Do not modify the plug provided with the appliance – if it will not fit the outlet, have a proper outlet
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, this instant hot water dispenser should be
regularly examined for leakage 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.
12
13
Electric Shock Hazard: To prevent electrical shock, disconnect power before
servicing unit. Use only a properly grounded and polarized electric outlet.
Scalding Hazard: Do not allow
water to boil. May result in
severe burns.
Factory temperature pre-set
is 200˚F. To reset the
thermostat to 200°, turn
the indicator two notches
to the right of vertical.
Adjust the thermostat
slowly, turning the dial
clockwise to increase temperature
or counter clockwise to decrease
temperature, then activate faucet
handle for 20 seconds to bring in fresh
water to be heated at the new setting.
Allow 5-7 minutes for water to reach
new temperature.
Regularly inspect the unit for any signs
of leakage. If there are signs of water
damage, immediately remove the unit
from service.
To avoid water damage from leakage,
replace all cut, loose or split tubing.
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.
