3.0 Faucet Compatibility
Only "Open Vent" faucets function with an instant hot water dispenser tank. Connecting a standard
faucet will damage the tank and void the warranty.
IMPORTANT INFORMATION
This hot water dispenser produces instant hot water of approximately 98°C (208°F) as dispensed
from the faucet. This product is not intended to produce a continuous flow of hot water. The
standard model will produce up to 60 cups of water per hour at approximately 98°C (208°F). Due to
high water temperature, for safety reasons, the tank is not under pressure. Consequently, there is a
slight delay of water flow after the faucet has been turned on. This is normal and indicates that the
priming chamber is functioning properly.
•Do not extend the hot water outlet tube.
•Minimum working pressure: 220kPa (system might not work properly if the pressure is below the
requirement).
IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS CAREFULLY
When using all electrical appliances, basic safety precautions should always be followed including the
following:

1. Read all instructions.
2. To protect against electrical shock, do not place cord, plugs or appliance in water or other
liquid.
3. Do not operate any appliance with a damaged cord, plug, or after the appliance malfunctions.
4. Do not use outdoors or in damp area.
5. Do not let cord hang over edge of table or counter, or touch hot surfaces.
6. Do not use appliance for other than intended household use.
7. When using the appliance, provide 4 to 6 inches of air space around the entire unit for air
circulation.
8. Do not attempt to service this product. Repairs should be done by authorized service
personnel.
9. Do not let children operate. The water can cause severe burns.
4.0 SAVE THESE INSTRUCTIONS.
The alert symbols displayed at right point to important safety information to make you aware of
potential hazards that can cause serious injury or death. Please pay special attention to the
information following these alerts and warning. Failure to comply with these instructions can result in
property damage, serious injury or death.
4.0.1 ELECTRICAL REQUIREMENTS (Recommended Ground Method)
For your personal safety, the hot water dispenser is equipped with a power supply cord having a 3-
prong ground plug. To minimize possible shock hazard, the cord must be plugged into a mating 3-
prong, ground type outlet, grounded in accordance with all 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 ground, 3-prong outlet installed by a qualified electrician.
If codes permit and a separate ground wire is used, it is recommended that a qualified electrician
determine that the ground path is adequate.
A 220 volt, 60Hz, AC only 15 or 20 ampere fused, grounded electrical supply is required. It is
recommended that a separate circuit serving only your hot water dispenser be provided.
Note: Use an outlet that cannot be turned on/off by a switch
PRESSURE FREE HOT WATER DISPENSER CONCEPT
Unlike other household water dispenser, this dispenser tank is not pressurized for safety reasons. For
a conventional household water heater, the faucet valve is placed after the heater tank resulting in a
pressurized tank. For a hot water dispenser, the faucet valve is placed before the tank, creating an
"open vent" style faucet and consequently no pressure is built up inside the tank.
5.0 OVERVIEW

Make sure you have all necessary parts, tools as suggested on manual cover.
1. Determine a convenient location to mount your faucet. This can be existing sink hole in the
sink top, or you may drill another hole into the sink. As you determine the location of your
faucet, consider the container you will use with appliance, such as a large cooking pan.
Location of the hole should also provide easy access for tank connections.
2. The thickness of the sink must be less than 70mm.
3. Before connecting to the power source, the dispenser must be filled with water and the
thermostat turned to the OFF position.
4. Do not use an extension cord with this appliance. Appliance must be within 914mm of the
power source.
5. Plumbing connections must comply with all local codes and ordinances.
6. Do not use any pipe sealing compounds as they may get inside the dispenser causing an
objectionable taste and odour.
IMPORTANT: Observe all governing codes and ordinances.
Faucet may be installed in spray hose opening in sink or drilled hole. If drilling another hole is needed,
the 35mm max. dia. hole is required.
Tank must be mounted vertically.
Quick-connector fittings connects to cold water supply line
See step 4 of installation for optional connections and instructions.

6.0 INSTALLATION
Before you begin
1. Determine where you will install your hot water dispenser. The faucet can be mounted in an
existing hole in the sink, or drill a 35mm hole in your sink.
2. Stainless Steel: You need a 35mm knockout punch available at most hardware stores or drill
a hole with an expandable drill.
3. Porcelain: Proper tools are required to drill through a porcelain or cast iron sink. If you are
not familiar with this process you should consider having this done by a professional plumber.
Do not attempt to drill without these special tools as you may severely damage your sink.
BE SURE TO CONFIRM YOUR FAUCET'S COMPATIBILITY WITH THIS APPLIANCE. FAUCET
MUST BE "OPEN VENT STYLE".
STEP 1 - Mounting Tank
Position tank vertically beneath faucet so flexible tube from the faucet reaches the centre faucet
supply tube on the tank.
Be sure dial is in OFF position during installation
NOTE: The tank must be positioned so the hose to the faucet does not twist
or kink
STEP 2 - Faucet Installation
Follow the installation instruction of the faucet manual.
STEP 3 - Connect Faucet to Tank
1. Connect 1/4" faucet copper line to the rear tube at the top corner of the tank with the quick-
connect fitting supplied with the appliance. Push line straight into quick-connect fitting as far
as possible for both connections.
2. Connect silicone tube to the centre outlet tube on top of tank.
3. Use cable ties to fix the connection tightly. It will create a secure connection when properly
installed.
Be sure the hose is not twisted or kinked. Hose may be shortened if necessary.
NOTE: DO NOT lengthen the hot water hose - dispenser performance will be impaired and
warranty will be void.

STEP 4 - Connect Cold Water Supply
Refer to installation instructions included with faucet if necessary.
Cold water is supplied to the tank through the faucet. Connect the cold water line to the faucet using
the 1/4" supply line and the quick-connect fitting.
Make sure the cold water connecting to the faucet is filtered. It is suggested that a shut-off
valve be installed between this connection and the cold water supply line.
Another common installation method is with the use of a saddle valve if a saddle valve is used; follow
the manufacturer's installation guides.
Connection to a hot water supply is not recommended. If a water filter is used, water pressure
to the tank should not drop below 240kPa or 35psi (2.4 bar).

STEP 5 - Check for Leaks
1. Open valve in water line.
2. Turn faucet on (push to unlock) to fill tank (about1 minute). When tank is full, water will flow
from faucet.
3. Turn faucet off. Check for leaks.
STEP 6 - Prepare for Power
Double check the thermostat control dial is in the OFF position. Thermostat control dial controls the
water temperature, not the water flow or delivery.
IMPORTANT INFORMATION
This dispenser is equipped with a Self re-setting thermal fuse
Turn the thermostat to OFF position and fill tank with water before plugging the power cord from the
tank into an electrical outlet.
If tank is empty and the thermostat set in the ON position when the power cord is
Connected, the self re-setting fuse in the heater control will disconnect the current to the heater after
approximately one minute, thus protecting the heater from a "dry start" failure. The fuse in the heater
control will self-reset after approximately 1/2 hour. Turn on the water supply to the tank and continue
the installation.
Continued misuse will cause damage to the appliance and is detectible thus, voiding the warranty.
