by the water heater interface control. To comply with
safety regulations the temperature was set at 122°F
before the water heater was shipped from the factory.
The illustration at the
left shows the water
temperature setting.
Refer to the
Operating Instructions
in this manual for
detailed instructions
in how to adjust the
water temperature.

DANGER: Hotter water increases the potential for Hot
Water SCALDS.
