DANGER

THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE

THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT

WATER TEMPERATURES REQUIRED FOR AUTOMATIC

DISHWASHER AND LAUNDRY USE CAN CAUSE SCALD

BURNS RESULTING IN SERIOUS PERSONAL INJURY

A N D / O R D E AT H . T H E T E M P E R AT U R E AT W H I C H

INJURY OCCURS VARIES WITH THE PERSON’S AGE

AND TIME OF EXPOSURE. THE SLOWER RESPONSE

TIME OF CHILDREN, AGED OR DISABLED PERSONS

INCREASES THE HAZARDS TO THEM. NEVER ALLOW

SMALL CHILDREN TO USE A HOT WATER TAP, OR TO

DRAW THEIR OWN BATH WATER. NEVER LEAVE A CHILD

OR DISABLED PERSON UNATTENDED IN A BATHTUB

OR SHOWER.

THE WATER HEATER SHOULD BE LOCATED IN AN AREA

WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS TO

SET TEMPERATURES.

The water temperature is controlled using the Temperature Control

UP/DN Button on the Display at the front of the unit (See Figure 1).

This control utilizes two temperature probes to determine the tank

temperature. The primary temperature probe is located at the top

of the tank and the other is near the water inlet.

FEATURES
