In-Sink-Erator
Instant Hot Water Dispenser
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.
SAFETY SYMBOLS!
The warning symbol alerts you to potential hazards or unsafe
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 warranty. 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.

Dispenser head configurations covered in this installation guide.
If your dispenser head still varies, you may require another installation
guide.
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.
Personal Injury

HOW YOUR HOT WATER DISPENSER WORKS
Water is electrically heated to near-boiling (190˚F/88˚C) in a compact tank that mounts under the sink. A thermostat maintains it at this approximate temperature.
When you turn the handle, cold water enters the tank and forces hot water out of the faucet. The system is vented so the tank is not pressurized.
Due to the unique operation of your instant Hot Water Dispenser, you may experience a slight delay in the dispensing of water after the handle is actuated.
This assures maximum water temperature and is not indicative of a problem with the unit.
Important:
Do not install this appliance in public areas or institutions where there is unsupervised access to this appliance.

INSTALLATION INSTRUCTIONS
1 IF YOU WISH TO USE THE HOLE IN WHICH THE SPRAY
HOSE IS LOCATED, FOLLOW THESE EASY STEPS:
1. Turn off water supply
2. Remove nut that connects spray hose at bottom of faucet.
3. Remove nut that connects spray hose at bottom of washer flange in spray
hole using ordinary wrench or basin wrench.
4. Plug faucet tube opening with either a 1/8" plug or a 1/4" cap (not supplied)
What if you don’t use a sprayer hole?
You can cut a mounting hole through a stainless steel sink with a 1-1/4" (32mm)
chassis punch. Rent or purchase one at your hardware or electrical supply
store. Or, mount the Hot Water Dispenser’s head in a 1-1/4" (32mm) hole drilled
through your countertop with a hole saw. Don’t attempt to drill a hole through a
cast iron or porcelain covered sink unless you have the proper tools and skills.
2 STRAIGHTEN DISPENSER TUBES
There are two copper tubes exiting from the dispenser head, which are curved for
easier packing and shipping. Straighten, holding the head down with one hand
while working the tubes down slowly with your other hand. See Caution, Step 9.
3 INSTALL DISPENSER HEAD
H-990
1. Place dispenser assembly (without handle) thru sink hole.
2. Place toggle on bolt from bottom, then the nut and tighten by bolt head
located on top of the faucet. Note that the open area on the toggle is positioned
around the copper lines and vent lines. Note that the toggle is mounted with
the nut holder facing down.
3. Hand tighten toggle bolt until faucet cannot easily be twisted from side to
side. Torque on bolt should not exceed 30in. Lbs.
Note: Ensure toggle bolt head is seated in recess
H-770
1. Place the dispenser head with #10-24 mounting screw and gasket attached
down through the mounting hole. Then while an assistant holds the dispenser
head in place, secure the head as shown in 3-2 and 3-3.
2. Working from below the sink, place semi-circular metal mounting washer
over the mounting screw.
3. Now, simply tighten.
GN/HC
1. Remove wing nut from valve body for 1-1/4" (32mm) sink hole, stack 1-5/8"
rubber washer, 1-5/8" stainless washer or 2-1/4" colored washer. For cast iron
sink or hole greater than 1-1/4", stack 1-5/8" rubber washer with 2-1/4" stainless or 2-1/4" colored washer.
2. Have someone hold the head assembly from above and, while working
from under sink, slide the 2-1/4" fiber washer into place and tighten the
assembly using the plastic wing nut.(A): Shroud (B): Set screw for adjusting
head direction (C): countertop or sink 7/8" max (22mm) (D): Wing nut (E):
2-1/4" fiber washer (F): 1-5/8" rubber washer (G): 1-5/8" stainless washer
or 2-1/4" colored washer
3. Cast iron sink hole greater than 1-1/4" (32mm) (A): 2-1/4"SS or colored
washer (B): 1-5/8" rubber washer (C): Fiber Washer (D): Wing nut
If desired, the spout may be rotated 90˚ in either direction to allow the dispenser levers to be on the left or right side of the spout. To do this, remove
shroud which snaps onto inner cover. Using small screwdriver, loosen set screw
on left side of valve body and rotate spout in desired direction. Do not pull
spout up or out! RETIGHTEN SET SCREW AND REPLACE SHROUD.
4 MAKE CONNECTION TO COLD WATER SUPPLY LINE
1. The recommended connection can be made using a shutoff valve. This is a
complex installation and should only be attempted by an experienced installer
with the proper knowledge and tools.
2. Where plumbing codes permit, a saddle valve (not supplied) can be used to
supply water to the dispenser. If the saddle valve is to be used on copper pipe
it is not necessary to pre-drill any holes. Simply follow the directions for “selfpiercing attachments” included with the valve. (Attach the valve to a cold water
supply line) Note: Saddle valves are susceptible to clogging.
Product Damage
Excessive use of paste or tape pipe sealants on water connections can
clog small water passages.
Electric Shock Hazard
Never use an electric drill to drill into water pipes. It can result in an electric
shock. Use a cordless or non-electric hand drill.
