Digital Instant Hot Water Dispenser Instruction Ver. A-E 2022/12/1

IMPORTANT INFORMATION
This digital hot water dispenser produces instant hot
water of approximately100ﾟC (212ﾟF, max.) 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 88ﾟC (190ﾟ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 activated.
This is normal and indicates that the expansion
chamber is functioning properly.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person
responsible for their safety. Children should be
supervised to ensure that they do not play with the
appliance.

The alert symbols displayed above 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 warnings. Failure to comply with these
instructions can result in property damage, serious
injury of death.
ELECTRICAL SUPPLY
THIS APPLIANCE MUST BE EARTHED, In the event of a
malfunction, earthing provides a path of least
resistance for the electrical current, thus reducing the
risk of electrical shock.
This dispenser is rated 120VATTS , 50/60 Hz , maximum
10.9AMPS and should be connected to a main
distribution board or consumer unit.
Before you begin connecting the electrical supply, you
should be thoroughly familiar with electrical power and
procedures. If you are not, consult an electrician.
IS THE DISPENSER EARTHED?
THIS APPLIANCE MUST BE EARTHED.
In the event of malfunction or breakdown, earthing
reduces the risk of shock. This dispenser must be
connected to an earthed, metal, permanent wiring
conductor and connected to the equipment earthing
terminal or lead on the dispenser.
HOT WATER CONCEPT
Unlike a household water heater, 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.
Operating inlet water pressure requirements :
172kPa (1.7bar, 25psi) Min and 861 kPa (8.6bar, 125psi)

BEFORE YOU BEGIN INSTALLATION
1. Before connecting to the power source, the tank must be filled with water.
2. Do not use an extension cord with this appliance. Appliance must be within approximately 36" (914 mm) of the power
source.
3. Do not use any pipe sealing compounds as they may get inside the dispenser causing a discomforting taste and odor.
4. Determine a convenient location to mount faucet and tank. Important considerations when determining location
include:
•Installation must comply with local plumbing codes.
•Read these instructions for the dispenser and heating tank before proceeding.
•Dispenser will drip occasionally in use after water is drawn and tank is heating more water. This is normal.
•Make sure the tank outlet supply tube has no loops or low areas.
•Tighten fitting with an adjustable crescent or open wrench. Never use a pipe wrench.
•Never dispense both hot and cold water at the same time.
•Dispenser will occasional drip and spurt during water boiling. Lower target temperature to prevent spurting.
•Be sure faucet is positioned where there will be no contact with the water flow when turning the faucet on and off to
avoid burns.
•Be sure to allow for 4" to 6" (102 mm to 154 mm) of space around the front and sides of the tank to allow for air
circulation.
•The container(s) you will use with the appliance such as a large cooking pan or carafe.

5. Mounting Hole Size Requirements :
•Existing hole in sink (the spray hose opening for example) or drilling another hole into the sink or countertop, You will need a 1
1/4“ (32 mm) or 1 3/8” (35 mm) hole in your sink.
•Drilling into a stainless steel sink : You need a 1 ¼” (32 mm) or 1 3/8" (35 mm) knockout punch (available at most hardware stores)
or drill a hole with an expandable drill.
•Drilling into a porcelain sink : 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 sink holes without these special tools as you may severely damage your sink.
•Location of the hole should also provide easy access for tank connections.
•Tank must be mounted close to faucet to avoid kinking or pulling of lines. Lengthening of lines is not recommended as this may
diminish performance of the appliance and void warranty.
•The thickness of the sink or counter must be less than 1 3/8" (35mm).
