4.0 OPERATION
(Continued)
FRONT PANEL CONTROLS:
1. Power Switch
This switch turns the main power to the unit on and off. It must be turned on to heat the
kettle. It should be turned off when the kettle will not be in use for long periods.
2. (Red) Cooking Light
This light is on whenever the main burner gas is on. On units with standing pilots this light
may be on without the burners being on if the pilot is extinguished. See lighting instructions.
3. (Amber) Low Water Light
All kettles are supplied with sufficient distilled water in the pressurized jacket. If at any time
the water level falls below that required for proper operation, the kettle will not heat and this
light will come on. See “Adding Water” section of service instructions.
4. Thermostat
The thermostat selects the desired internal kettle operating temperature.
5. Pressure Gauge
The pressure gauge indicates the internal operating pressure of the kettle. When cold, the
gauge should be in the green vacuum zone. If it is not, refer to “Re-establishing Vacuum”
section of service instructions. Under normal operation with the kettle empty (thermostat
set at 275 degrees Fahrenheit) the pressure shall reach 30 psi. When loaded the pressure
may be considerably less.
6. Sight Glass
The sight glass indicates the minimum and maximum water level within the kettle. If water
level falls below minimum level more distilled water should be added. See “Adding Water”
section of service instructions.
7. Pressure Relief Valve
The pressure relief valve is a safety device which prevents the internal kettle pressure from
ever exceeding 50 psi. It should never be tampered with.
