A.If the set point temperature of the control is correct, no adjustment is necessary.
B.If the set point temperature of the control is not correct, adjust the temperature control. Repeat step 4 until the correct temperature is achieved.
To set the temperature control for optimum steamer operation, the elevation above sea level for the service location must first be determined.
The elevation is used in conjunction with the elevation table below, to determine the correct set point temperature for the control.
NOTE: If the set point temperature is too high, the excess boiling action will cause water droplets to exit the steam vent pipe, and cause high water usage.
1.Remove right side panel as outlined under
"COVERS AND PANELS".
2.Place a thermocouple approximately one inch down in the center of steam vent pipe.
3.Turn steamer on by selecting "continuous" mode.
4.Allow steamer temperature to stabilize by completing two heating cycles.
5.Record the temperature reading when "heater" light goes out.
6.Using the elevation table, compare the recorded temperature to the temperature listed for the specific elevation.
NOTE: Use temperature scale on control dial plate for reference only. The scale represents dial turns in 1°F increments, not the actual temperature. When calibrating, use the recorded temperature taken from thermocouple.
1)Turn the temperature control dial clockwise to increase temperature or counterclockwise to decrease temperature.
