DANGER: There is a hot
water scald potential

too high. Households with
small children, disabled or
elderly persons may require a
120°F (49°C) or lower
temperature setting to
prevent contact with HOT
water.

Water Temperature Setting
The temperature of the water in the water
heater can be regulated by setting the
temperature on the front of the remote
control.
Safety factors should be considered when
selecting the water temperature setting of the
water heater’s remote control.
The remote control was set at 100°F (38°C)
before the water heater was shipped from the
factory. This is the recommended starting
point.
Water temperatures above 125°F (52°C) can
cause severe burns or death from scalding.
Be sure to read and follow the warnings
outlined in this manual and on the label
located on the water heater.
Mixing valves are available for reducing
point of use water temperature by mixing
hot and cold water in branch water lines.
Contact a licensed plumber or the local
plumbing authority for further information.
(See page 4 for more details.)
The chart below may be used as a guide in
determining the proper water temperature
for your home.
