The Installation, Care and Use of Your New
®
“Hot-1” Hot
Water Dispenser
How your hot water
dispenser works
Water is electrically heated to a brewing/cooking hot 190°F (88° C)* by a
compact tank that mounts under the
sink. A thermostat maintains it at this
approximate temperature. When you
push the valve lever, cold water enters
the bottom of the tank and forces hot
water out of the faucet. The system is
vented so the tank is not pressurized.
Valve lever design may vary

What you should know before you begin
This unit usually mounts behind the sink. Be sure you have enough room between the sink and the wall to mount the unit (see mounting
dimensions). When determining hole location for the unit, ensure that the dispenser spout will drain into the sink and the valve lever will not
hit the back wall or counter.
Connecting the dispenser to your cold water supply requires no
special plumbing. All details are covered in the installation instructions. Be sure that all 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 20 pounds per square inch (138kPa). This could prevent the unit from aspirating properly.
A standard 115-volt grounded electrical outlet is required under
the sink for the dispenser’s electrical power. The current drain is
4.3 amps only when the tank is heating. Assure 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.
These are the tools and materials you will need
Cold water line within 16" (40
cm) of the dispenser. A shutoff valve and/or T-fitting(s) to
connect the dispenser to the
cold water line (see step 3 for
examples of connections that
can be used).

These are the tools you may need
Hand drill. If you have a
galvanized water supply
pipe, you may need a
non-electric drill to make
a small hole.
Basin wrench. If you
intend to use the hand
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 of
installation instructions
for details.
Chassis punch. If you
need to punch a mounting hole in your stainless
steel sink you may need
a 1-3/8" (35 mm) chassis
punch.
Personal Injury
• Dispenses 190°F (88° C) water
which can instantly cause scalds
or burns. Use care when operating
this appliance.
• Do not allow children to operate
this appliance.
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.
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 should be used in those applications
where any leakage could cause property damage.
Electric Shock Hazard
• Disconnect power before installing or servicing unit
• Use only a properly grounded and polarized electric outlet.
Important
• Any time you plan on being away from home for an extended
period of time, unplug the unit’s electrical cord. See step 6.
Personal Injury
• This tank is a non-pressure tank. Do not modify this system.
Do not close vent tube or connect other type faucets or
valves to the tank.
• This unit does not contain a drain plug and should not be
installed where periodic draining is required such as summer
homes. The unit can be drained only by removing it from the
sink and turning it upside down. If draining is necessary, we
recommend that you install an ISE Model H-770 hot water
dispenser.

Doing so may result in clogging of water
passages.
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 predrill any holes. Simply follow the directions
for “self-piercing attachment” included with
the valve.
Note: Saddle valves are susceptible to
dclogging.

Fire/Product Damage
• Do not remove or alter the thermal
safety fuse.
• If you suspect the thermal fuse is
open, contact your ISE Authorized
Service Center
Product Damage
• Do not connect electric power until
tank is filled with water.
Failure to do so may damage heating element or thermal safety fuse
and will void your warranty.
Until you have read and
understood the following:
Once the electrical cord is plugged in, it will
take ten to 15 minutes for the water to reach
its 190°F (88°C)* temperature.
(See adjusting temperature procedure).
Your dispenser should now be operating
properly.
When the 190°F (88°C)* temperature is
being reached, you can expect a gurgling or
hissing sound within the tank. This is normal. You might also experience steaming
and/or spitting hot water to come out of the
faucet without turning it on. This also is a
normal function on any initial start up.
Note: The dispenser perks like a coffee
percolator just before the electric thermostat
shuts it off. The rumble is caused by gas
bubbles being driven off by the boiling
water. This is part of the regular operation of
the dispenser.
Now, carefully turn on the faucet for about
20 seconds to draw off that steaming water
and allow the water in the tank to reheat.
Repeat this step one or two more times. This
allows the functional parts of the dispenser
to heat up evenly and work in balance, preventing the steaming and spitting condition.
If steam is still emitted from the faucet, a
thermostat adjustment may be necessary to
slightly decrease the water temperature.
High altitudes: High elevations (Denver,
Colorado, etc.) may require the thermostat
to be lowered to keep the water from boiling
(see adjusting temperature procedure).

Service/Maintenance Instructions
Adjusting Temperature
What if water is dripping from the spout?
If water drips from the spout, draw 2 or
3 cupfuls while unit is heating. This will
drain any water out of the unit’s expansion chamber. If water still drips prior
to the automatic thermostat shutting
off (you can hear it), turn thermostat
to a slightly lower temperature setting.
If the water pressure occasionally drops below 20
pounds per square inch (138kPa), the expansion
chamber of the tank may not be draining properly.
In such a case, water may drip out of the spout until the incoming water is hot enough to turn off the thermostat. As soon as
adequate water pressure is restored, the next drawing of water
will clear the expansion chamber. Occasional drops in water
pressure will not harm the operation of your unit.
Electric shock hazard
• To prevent electrical shock, disconnect power before removing access cover to service the thermostat.
Scalding hazard
• Do not allow water to boil. May result in severe burns.
Fire/product damage
• Do not remove or alter the thermal safety fuse.
• If you suspect the thermal fuse is open contact your ISE
Authorized Service Center.
Note: Use only mild cleaners to clean the dispenser spout
and plastic components. Use of cleaning agents containing
acids, alkalines and organic solvents will result in deterioration of plastic components.
What to do if something goes wrong
1. If the dispenser’s flow of water slows or stops, make sure
the shutoff valve is not plugged or turned off. To unplug the
valve, turn it all the way off and then open it all the way. This
may dislodge any foreign material. If this does not work, then
unplug the power cord and contact your service center.
2. Be sure dispenser is plugged firmly into a properly grounded
outlet.
Check that fuses and circuit breakers are working. Reread
instruction booklet to assure that you are using correct
operating procedure. Many unnecessary service calls
result in the service agent doing what the owner can do
for himself or herself.
3. Contact your local authorized service center. For the location of your nearest factory authorized service center call
1-800-558-5700 USA (1-800-367-9811 Canada).
4. Write to us if a satisfactory solution is not reached in the
steps above. Our address is shown below.
The thermostat is preset at the factory at approximately 190° F.
If you wish to adjust the water temperature, turn the thermostat
adjustment screw clockwise to increase the temperature and
counterclockwise to decrease it (see illustration above). The
cover must always be in place for the thermostat to respond
properly. Wait for water to heat up or to cool down. Then, draw
some water. If temperature still is not to your liking, repeat the
procedure. Do not allow water to boil.
