1830A215-Mar2008 1930A215-Mar2008 A. CLEANING: New units are wiped clean at the factory to remove any visible signs of dirt, oil, grease, etc., remaining from the manufacturing process. Each fryer vessel should be thoroughly washed with hot soapy water to remove film residues, installation dust, or debris; and then wiped dry before being used for food preparation. B. STARTUP: The fryers are tested, adjusted and calibrated prior to being shipped: however adjustments may be necessary on instal- lation to meet local conditions, high or low gas pressure, differences in altitudes, variations in gas characteristics, and to correct pos- sible problems caused by rough handling or vibration during shipment. Initial calibration or adjustment is the responsibility of the customer and will not be covered by the Ultrafryer Systems warranty. NOTE: Calibration and adjustments must be performed by qualified personnel. C. LIGHTING INSTRUCTIONS: Each fryer is equipped with a spark ignition system; to test this system, perform the following steps, in sequence: 1. Ensure the Ultrastat 25 Controller is off. 2. Fill the fryer vessel with hot or cold water to the SHORTENING LEVEL mark. CAUTION : IF THE MAIN BURNERS ARE OPERATED WITH THE VESSEL EMPTY, THE HEAT WILL CAUSE THE JOINTS OF THE FRYER VESSEL TO BE PLACED UNDER UNDUE STRESS AND MAY CAUSE THE HEAT EXCHANGER VESSEL TO WARP OR BUCKLE, VOIDING WARRANTY. 3. Turn the manual gas valve behind the fryer service access door of the fryer to the OFF position and wait FIVE (5) minutes for any accumulated gas to disperse. 4. ENSURE the MAIN gas shutoff is in the ON position, MANUAL VALVE on the combination GAS CONTROL VALVE (located behind the fryer service access door) is in the ON position, and the Vent Hood EXHAUST FAN is ON. 5. Turn the manual gas valve to the ON position. 6. Place the ULTRASTAT 25 Cooking Computer into the MELT MODE. WARNING!!! DO NOT USE A MATCH OR CANDLE TO LIGHT A FRYER… EVER! D. SEQUENCE OF IGNITION: When the lighting instruction steps are performed in the sequence listed above, the following will occur: 1. Blower will come ON, activating the air pressure switch. 2. The air pressure switch will CLOSE completing the electrical circuit to the transformer. 3. The transformer will supply 24 volts to the IGNITOR MODULE and GAS CONTROL VALVE, and the ignitor will SPARK lighting the gas in the burner. WARNING!!! WHEN CHECKING FOR BURNER PERFORMANCE, DO NOT STAND WITH YOUR FACE CLOSE TO THE BURNER…. IT MAY LIGHT WITH A “POP” AND COULD FLASH BACK AND CAUSE FACIAL BURNS. NOTES: 1) If the burner flame fails, it will be sensed by the SPARK IGNITOR; the Spark Ignitor Module will open the electrical circuit to the GAS CONTROL VALVE, shutting off gas to the burner. 2) If the blower fails, the air pressure switch will open the electrical circuit to the TRANSFORMER, removing electrical power from the SPARK IGNITOR MODULE and GAS CONTROL VALVE, shutting off gas to the burner. E. BURNER OPERATION TEST: Perform above LIGHTING INSTRUCTIONS and observe operation of the burners. When satisfied that the burner is operating properly, drain the fryer vessel of water and dry the vessel thoroughly; then fill the fryer vessel with shortening according to the instruction, below. F. SHORTENING INSTALLATION: 1. LIQUID SHORTENING: When using liquid shortening fill the fryer with cold shortening 1/2" (13mm) BELOW the “E” in the word LEVEL. When the shortening is heated, ensure it is even with the “E” in the word LEVEL. 2. SOLID SHORTENING: a) Cut a block of solid shortening into small pieces. b) Place small pieces of solid shortening EVENLY on top of the HEAT EXCHANGER TUBES or THOROUGHLY PACK these pieces of solid shortening between, below, and above the HEAT EXCHANGER TUBES. While packing solid shortening is messy and time-consuming, it is the fastest way to melt solid shortening.
