Resumen del manual
Next, ensure the ignition wire is connected properly at both ends and examine it for obvious signs of damage. Again, if damage is due to excessive heat in the fryer, that problem must also be corrected. DANGER MAKE SURE YOU ARE HOLDING THE INSULATED HANDLE OF THE SCREWDRIVER AND NOT THE BLADE. THE SPARKING CHARGE IS APPROXIMATELY 25,000 VOLTS. Check for proper operation by disconnecting the wire from the ignitor, inserting the tip of a screwdriver into the terminal, and holding it near the frame of the fryer as the power switch is placed in the "ON" position. A strong, blue spark should be generated for at least 11 seconds. Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pressure, but may also be the result of variations in the kitchen atmosphere. Verify incoming gas pressure in the same way as for "popping", discussed in the preceding paragraphs. Variations in the kitchen atmosphere are usually caused by air conditioning and/or ventilation systems starting and stopping during the day. As air conditioning/ventilation systems start and stop, the pressure in the kitchen may change from positive or neutral to negative, or vice versa. Changes in airflow patterns may affect flame intensity. Flames "rolling" out of the fryer are usually an indication of negative pressure in the kitchen. Air is being sucked out of the fryer enclosure and the flames are literally following the air. If negative pressure is not the cause, check for high burner-manifold gas pressure in accordance with the procedures in Section 1.4. An obstructed flue or a faulty blower, which prevents the fryer from properly exhausting, may also be the cause. Excessively noisy burners, especially with flames visible above the flue opening, may indicate that the burner gas pressure is too high or the gas valve vent-tube is blocked (if applicable). If the gas pressure is correct, and the vent-tube is unobstructed (if applicable), the gas valve regulator is probably defective. 1-22 24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.8.3 Improper Temperature Control Temperature control, including the melt cycle, is a function of several interrelated components, each of which must operate correctly. The principal component is the temperature probe. Depending upon the specific configuration of the fryer, other components may include the Thermatron board, the controller itself, and the ignition module. Improper temperature control problems can be categorized into melt cycle problems and failure to control at setpoint. Failure to Control at Setpoint In fryers equipped with a Thermatron temperature controller, the #1 problem may be with the temperature probe improperly positioned. Other causes may be the Thermatron board or the potentiometer. Possible causes are that the potentiometer is out of calibration, or the temperature probe or Thermatron board is defective. Refer to Section 1.6 for instructions on calibrating the Thermatron temperature controller. 1.8.4 Filtration Problems Whenever the complaint is "the pump is running, but no oil is being filtered", check the filter paper or filter leaf (screen) connections and ensure they are properly connected. Ensure the filter paper or filter leaf is not clogged with food debris or sediment, and is properly assembled. If the pump motor overheats, a circuit breaker in the filter circuit will trip and the motor will not start until it is reset. If the pump motor does not start after pressing the circuit breaker, press the red reset switch located on the rear of the motor. If the pump then starts, something caused the motor to overheat. Maybe several frypots were filtered one after the other and the pump got hot. Letting the motor cool down for at least a half-hour is all that is required in this case. More often, the pump overheated for one of the following reasons: • Shortening was solidified in the filter leaf or filter lines. • The operator attempted to filter unheated oil or shortening. Cold oil and shortening are thicker and cause the pump motor to work harder and overheat. If the motor runs but the pump does not, there is a blockage in the pump. An incorrectly assembled filter leaf allows food particles and sediment to pass through the filter pan and into the pump. When sediment enters the pump, the gears bind up causing the motor to overheat, tripping the thermal overload. Solidified shortening in the pump will produce the same result. 1-23 24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES A pump seized by debris or hard shortening must be disassembled, cleaned and reassembled as follows: 1. Disconnect power to the filter system. 2. Remove the front cover of the pump to access the gears inside, if the pump is accessible while still inside the cabinet. If the front cover is not accessible, the pump must be removed from the pump motor (remove input/output plumbing from the pump prior to removing pump). Remove setscrews to disengage the pump...
