**SERVICE INSTRUCTIONS** and **TROUBLE SHOOTING GUIDE**
FOR AUTHORIZED SERVICE PERSONNEL ONLY
CAUTION: DISCONNECT POWER BEFORE ATTEMPTING ANY ELECTRICAL REPAIRS.
THERMOSTAT ADJUSTMENTS:
NOTE:
The thermostat is behind the lower front panel. If water temperature is less than 197 degrees F
(92 degrees C) slowly turn thermostat knob clockwise until ready light goes out. When temperature of water
approaches 197 degrees to 203 degrees F (92 degrees to 95 degrees C) slowly turn thermostat knob
counterclockwise until the green ready light comes on. If water temperature cannot be increased when
thermostat knob is turned fully clockwise, then proceed as follows:
Pull off knob. Place a small screwdriver into the center of thermostat shaft. While observing green ready
light and temperature on thermometer, hold shaft and turn small adjustment screw in center counter-
clockwise until green ready light goes out. When temperature of water approaches 197 degrees - 203
degrees F (92 degrees - 95 degrees C), slowly turn screw clockwise until ready light comes on. Turning
screw clockwise lowers temperature; counter-clockwise raises it. After adjusting center screw, place nail
polish or glyptol on screw to set in position.
NOTE:
As a final check, measure water temperature at Spray Head . Temperature should be 197 degrees
to 203 degrees F (92 degrees to 95 degrees C).
IF WATER FAILS TO HEAT:
1. If Red power switch does not light, check heater switch in the back, toggle should be in the up position .
Check power supply outlet, replace fuse or reset circuit breaker if necessary. If power is good, check rear
heater switch for continuity and replace if switch stays open.
2. If water still fails to heat, disconnect line cord and check out tank heater, thermostat and high
temperature safety shutoff. Replace needed parts.
