Water Heater Capacity and Increasing Temperature
Setpoint (For Water Heaters without an Integrated
Mixing Valve):
The water heater temperature setting strongly impacts
the amount of usable hot water available for showers
and baths.
• Energy consumption/savings and efficiency testing of
water heaters is performed according to Department
of Energy (DOE) requirements specified at the date of
manufacture.
• Safety regulations require a factory setting no greater
than 125°F (52°C) for all new water heaters. Therefore,
if your old water heater was set to a hotter temperature
than your new water heater with a factory set setpoint of
120°F (49°C), the new water heater may seem to provide
lower capacity than your old water heater. This can be
corrected by increasing the temperature setpoint.
• Increasing the water temperature setpoint may improve
the cleaning performance of dishwashers and washing
machines.
• The user can adjust the temperature setting to meet
their needs. Always read and understand the safety
instructions contained in the owner’s manual before
adjusting the temperature setpoint.
Extended Shutdown Periods
If the water heater is to remain idle for an extended
period of time, the power and water to the appliance
should be turned off and the water heater drained to
conserve energy and prevent a buildup of dangerous
hydrogen gas. This unit has no power button, power
can only be shut off at the circuit breaker or disconnect
switch.
The water heater and piping should be drained if they
might be subjected to freezing temperatures.
After a long shutdown period, the water heater’s
operation and controls should be checked by qualified
service personnel. Make certain that water is flowing to
water heater again before placing it in operation.
General Operation
This water heater does not store water like a
conventional tank style water heater. It uses a series
of flow rate and temperature sensors to heat water.
When you turn on the hot water faucet, this water heater
recognizes water demand and heats water to the set
point temperature to meet this demand. When the water
faucet is turned off, the water heater will also turn off.
Exterior Surfaces
Hand wash with damp cloth, using only warm water. Wipe dry using a dry, clean cloth.
DANGER
Risk of Scalding
Before conducting any maintenance on plumbing
connection, make sure no one will be exposed to the
danger of coming in contact with the hot water. The
water may be hot enough to create a scald hazard. The
water should be released into a suitable drain to prevent
injury or property damage.
It is recommended to perform routine maintenance on
your water heater. Properly maintained, your water
heater will provide years of dependable trouble-free
service.
Inspect the inlet and outlet water connections on
an annual basis for any signs of damage or failure.
Look for any signs of leakage, damage, or cracks in
each connection. Make sure not to over tighten the
connections to avoid damage to internal connections of
the water heater.
CAUTION
Risk of Shock -
Shut off power
to the water heater before draining water.
Before conducting any maintenance on the water heater,
first shut off all power to the water heater directly at the
fuse or breaker box.
It is recommended to install the water heater with a
manual shut-off valve at the cold inlet plumbing location
to allow for easy maintenance and service.
When maintenance is performed on a home’s plumbing
system that may introduce air into the plumbing, it is
important to shut off all power to the water heater directly
at the fuse or breaker box. Failure to do so could cause
permanent damage to the water heater and void the
product warranty.
