Follow the appropriate instructions for each. Start-up Procedure, Standard Controls 1. Turn on water and power supply to appliance. 2. Close the manual blowdown valve if the units is not equipped with the optional automatic blowdown valve. 3. Open door of cabinet and turn on Power Switch. Pilot light will come ON and water will begin to enter boiler. Once water level has reached the proper operating level as indicated on water gauge glass the heating elements will be energized and heat the water. When steam pressure has reached 11 psi the elements will de-energize and cycle on and off between 9 - 11 psi. The boiler is now ready for steam generation. Start-up Procedure, CSD-1 Controls 1. Turn on water and power supply to appliance. 2. Close the manual blowdown valve if the units is not equipped with the optional automatic blowdown valve. 3. Open cabinet door and turn "ON" power switch. The green pilot light will come "ON.” Water will begin to enter the boiler. When enough water has entered the boiler the (red) “Low Water” pilot will come on for approximately 10 seconds and then the (amber) pilot light will come. 4. Press the “Reset” switch to begin boiler operation. The “Standby” pilot light will go off and the boiler will begin operation. When steam pressure has reached 11 psi the elements will de-energize and cycle on and off between 9 - 11 psi. The boiler is now ready for steam generation. 3.0 OPERATING INSTRUCTIONS (Continued) Normal Boiler Operating Cycle Water Fill Cycle On the initial filling of the boiler, units equipped with CSD-1 controls require that the “Reset” switch be pressed to initialize the safety lockout circuit. Once the water in the boiler has reached proper level, the level control will stop the flow of water to the boiler. As water is consumed in the production of steam, the level control will supply and maintain safe water level in the boiler. Firing Cycle The elements are operated by pressure sensing devices. On initial operation, the boiler should reach 11 psi in approximately 15 minutes. At this point the operating pressure switch will open, de-energizing the elements. When the pressure drops to 9.0 psi, the pressure switch closes, energizing the elements. Condensing Drain, (Optional) A thermostat is located in the drain assembly and is activated by the temperature of steam. The thermostat operates the cooling solenoid, supplying water to the drain to condense the steam. Automatic Blowdown Valve, (Optional) If the unit has an automatic blowdown valve, it is activated when the main power switch is turned “ON”. The boiler will drain when the main power switch is turned "OFF.” Safety Lockout Conditions High Temperature Condition, Standard Controls A high temperature safety device is installed on the boiler. Should the temperature exceed the limit of this device, the boiler will be shut down. As the temperature returns to a safe level, normal boiler operation will resume. High Temperature Condition, CSD-1 Controls A high temperature safety device is installed on the boiler. Should the temperature exceed the limit of this device, the boiler will be shut down and switch to a state of lockout. The “Temperature” pilot light (red), and the “Standby” pilot (amber), will come on. 3.0 OPERATING INSTRUCTIONS (Continued) High Pressure Condition, CSD-1 Controls A high pressure safety switch is installed on the boiler. Should the pressure exceed the limit of this device, the boiler will be shut down and switch to a state of lockout. The “Pressure” pilot light (red), and the “Standby” pilot (amber), will come on. Should this device fail to operate, the safety relief valve will open. Low Water Condition, Standard Controls A low water safety cut off is supplied with the boiler. Should the water level fall below normal operating levels, the boiler will shut down. If the water level is returned to a safe level, normal boiler operation will resume. Low Water Condition, CSD-1 Controls A second low water safety cut off is supplied with the boiler. Should the water level fall below normal operating levels, the boiler will shut down and switch to a state of lockout. The “Low Water” pilot light (red), and the “Standby” pilot (amber) will come on. SHUT DOWN Turn off power switch, open manual drain valve. If unit is equipped with automatic blowdown valve, it will open and drain the boiler. COOKER SECTION CAUTION: Live steam and accumulated hot water in the compartment may be released when the door is opened. Start-up procedures for your steamer must be completed once daily prior to operation (see instruction plate or above for boiler start up procedures). With ready pilot light on, preheat steamer compartment for one minute when the steamer is to be first used for the day or whenever the compartment is cold. 1. Close compartment doors and set timer to “1 minute”. 2. When buzzer sounds, set timer to the “OFF” position. 3. Steamer is now ready for cooking. 4. With cooking compartment preheated and ready pilot li...
