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 turn the tap, 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.
*APPROXIMATE
Do not install this appliance in public areas where there
is unsupervised access to this appliance.
What Should You Know Before You Begin

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 recom-
mended. The filter should not result in the water pressure to the dispenser drop-
ping 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 6.5 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
