INSTALLATION REQUIREMENTS
4
Electrical Requirements
A 120-volt, 60 Hz, AC-only 15 or 20 amp fused, grounded
electrical supply is required. It is recommended that a separate
circuit serving only your hot water dispenser be provided. Use an
outlet that cannot be turned on/off by a switch.
Recommended ground method
This appliance is equipped with a power supply cord having a
3 prong ground plug. To minimize possible shock hazard, the
cord must be plugged into mating, 3 prong, ground-type outlet,
grounded in accordance with all national and local codes and
ordinances. If a mating outlet is not available, it is the personal
responsibility and obligation of the customer to have a properly
grounded, 3 prong outlet installed by a qualified electrician.
Water Supply Requirements
If local codes permit, the hot water dispenser feed line should be
connected to the cold water supply line using a saddle valve or
another means for providing a 1/4
"
tube to connect to the
dispenser. If a saddle valve is used, do not use a piercing type or
3/16" saddle valve, which reduces water flow and clogs more
easily.
IMPORTANT: If local codes do not permit the use of saddle
valves, special feed valves can be obtained from your local
plumbing supply distributor.
Connection to hot water line is not recommended. Energy will be
wasted in heating the water twice and may produce an
undesirable taste.
A water filter is recommended if your water supply contains sand,
grit or other particles, or has a known taste or odor issue. If a
water filter system is used, the water pressure to the hot water
dispenser system from the filter needs to be a minimum of 20 psi
(138 kPa) for proper operation. If the water pressure to the hot
water dispenser system is less than 20 psi (138 kPa), a booster
pump can be added.
IMPORTANT: If the water pressure to the hot water dispenser
system is less than 20 psi (138 kPa), performance may be
affected.
INSTALLATION INSTRUCTIONS
Please complete the “Record your model’s information” section
on the front cover before beginning installation.
This hot water dispenser is not a water purifier. Some installations
may require a water filtering system to improve the quality of
water.
Installing the Faucet
1. Determine where you will install your hot water dispenser.
Check below sink to assure that reinforcing ribs, support
brackets or cabinet construction will not interfere with faucet.
2. Knock out plug from hole in sink or cut a hole in sink or
countertop.
NOTE: It is recommended that only a licensed plumber or
professional installer cut an opening in the sink or countertop.
3. Carefully straighten tubing so that it will go through hole in
sink or countertop.
4. Remove nut, metal washer and rubber washer from faucet.
Do not remove rubber o-ring in bottom of faucet base.
5. Feed tubing through hole in sink or countertop. Hold faucet in
place while installing rubber washer, metal washer and nut on
faucet from under the countertop. Securely tighten nut.

Installing the Tank
1. Position tank vertically beneath faucet so that the longer
copper tube from the faucet reaches the easy-connect fitting
on top of the tank.
2. Use a pencil to mark on the wall where the top of tank needs
to be located. Set tank aside. Mark a second line 2-1/4"
(5.7 cm) below the first line.
IMPORTANT: The tank must be positioned so that the copper
tubing and flexible tubing from the faucet does not kink.
3. Position mounting bracket on wall so that bottom of mounting
bracket is even with the lower line.
4. Use two screws (and plastic anchors if attaching to dry wall)
to fasten mounting bracket to wall. Hang tank on bracket.
IMPORTANT: Do not plug power supply cord into outlet at
this time.
5. IMPORTANT: Do not lengthen, twist or tightly bend tubing.
Do not use any sealing compounds.
Connect the longest 1/4" copper faucet tube to the rear easyconnect fitting on top of tank. Push tubing straight into fitting
as far as it will go. Pull on tubing. The tubing should not come
out when properly installed.
NOTE: If you need to remove tubing, push down on collet.
Pull tubing out of easy-connect fitting. It is easier to push the
collet down if a 1/4" or 7 mm open-end wrench is used as
shown.
6. Connect the flexible tube from the faucet to the center tank
tube. Make sure the flexible tube does not kink. To avoid
kinking, the tube may be shortened.
The center tank tube is not an easy-connect fitting. To
connect the flexible tube, use pliers and open the supplied
hose clamp. Slide the clamp onto the flexible tube about 2"
(5 cm) from the tube end.
7. Push the flexible tube down onto the tank tube as far as it will
go. Position the hose clamp so that it is close to the end of
flexible tube.
8. Install saddle valve kit or other plumbing parts as needed to
connect 1/4" tubing from faucet easy-connect fitting to cold
water supply line.
9. Flush line into bucket or pan to remove any debris that may
have been trapped in supply line during plumbing connection.
10. Check that water flows freely and that there are no leaks.
11. Connect 1/4" water supply line tubing to faucet copper tubing
with the factory-assembled easy-connect fitting. Push water
supply line tubing straight into fitting as far as it will go. Pull
on tubing. The tubing should not come out when properly
installed.
NOTE: If you need to remove tubing, push down on collet and
pull tubing out of easy-connect fitting.
IMPORTANT: For proper operation, do not remove the
factory-assembled easy-connect fitting from tube.
12. Open water line to faucet.

Complete Installation
IMPORTANT: The hot water dispenser can be damaged if the
following steps are not followed.
NOTE: Do not plug power supply cord into outlet.
1. Turn Temperature Control counterclockwise to “Off” position.
2. Push down and turn the faucet cap clockwise to open faucet.

NOTE: Make sure the Temperature Control is in the “Off” position
before plugging hot water dispenser into power supply. If tank is
empty and thermostat is in an “On” position when the power
supply cord is connected, the heater will overheat causing an
unpleasant taste, black specks in the water, and permanent
damage to the hot water dispenser.
4. Once water is flowing from faucet, the water heating tank has
been filled with water. Plug power supply cord into grounded
3 prong outlet.

HOT WATER DISPENSER USE
Before first use:
After the tank has been in operation for a minimum of 15
minutes, push and turn the faucet cap and allow water to flow for
about 1 minute. Release the faucet cap and allow the water to
reheat for about 15 minutes prior to use.
Check that all installation steps were completed.
The Whisper Quiet
®
System helps to
maintain a quiet home environment
during the operation of the hot water
dispenser.
Temperature control
The water temperature is thermostatically controlled. It can be
adjusted from “Off” to about 190°F (88°C).
To raise or lower the temperature, turn the Temperature Control.
The “Max” setting is recommended for best performance.
However, under certain conditions, it is possible for the water to
boil when the Temperature Control is set at “Max.” If you see
any vapor or hear boiling, turn Temperature Control to lower
temperature as necessary.
Dispensing hot water
Push down and turn the faucet cap clockwise and hold until
desired amount of hot water is obtained. There is a small delay
from the time the faucet cap is turned until hot water is
dispensed. This delay is normal.
