3.3Toggling Between Fahrenheit and Celsius Temperature Display
There are two versions of the SMS Controller: one that can be toggled between Fahrenheit and Celsius temperature display, and one that cannot. To determine which version you have, turn the controller off by pressing the ON/OFF switch. The display will go blank. Press the Simmer (right thermometer icon) switch. If Code appears in the display, the temperature display can be changed. If not, the display cannot be changed.
1.If Code appears in the display, press 1, 6, 5, 8. The display will be toggled from Fahrenheit to Celsius or from Celsius to Fahrenheit.
2.Press the Boil (left thermometer icon) switch to display the cookpot temperature. If an F follows the temperature, the display is in Fahrenheit; if a C follows the temperature, the display is in Celsius.
3.4Shutting the Cooker Down
Turn the unit off by pressing the Power 
switch. If shutting down at the end of the day, drain and clean the cookpot (and rinse tank, if so equipped), and put the cookpot and rinse tank covers in place.
3.5Boiling Out the Cookpot
To ensure that the cooker is free of contamination from manufacture, shipping, or handling during installation, the cookpot must be boiled out before first use.
1.Close the drain valve and fill the cookpot with a solution of cold water and 1 cup of detergent.
2.Place the unit into operation (see Section 3.2).
3.Press the simmer switch 
and allow the solution to simmer for at least 1 hour.
4.After the solution simmers for 1 hour, turn the unit off and add cold water until the solution is cool. Drain the solution and clean the cookpot thoroughly with a solution of dishwashing deter- gent and hot water.
NOTE: Do not use deliming solution to clean these units. Use of deliming solution will damage all stainless steel parts.
WARNING
When cleaning around the elements, be careful not to bend or otherwise damage the high-
limit thermostat capillary tube.
5.Rinse the cookpot at least twice by filling with clean water and draining. Dry the cookpot thor- oughly with a clean, dry towel.
6.For units equipped with a rinse tank, clean the tank with a solution of dishwashing detergent and hot water. Drain the tank and dry it thoroughly with a clean, dry towel.
