Part # 4521353 (06/17/09) Page 11ControlsAll EDU griddles are equipped with snap action thermostats.Before Operating the Griddle1. Remove the protective coating on the griddlesurface and side splashers using a milddetergent.2. Thoroughly rinse the griddle with a vinegar watersolution (3/4 cup vinegar per quart of water) and drythoroughly with a clean cloth.3. The Griddle must be seasoned before operation, see thegeneral maintenance and cleaning section for seasoninginstructions.Calibration Instructions1. Field calibration is seldom necessary and should notbe attempted unless experience with cooking resultsdefinitely proves that the control is not maintaining thetemperature to which the dial is set.2. Should calibration be required, use a test instrument(pyrometer) with a special disc type thermocouple orreliable “surface” type thermometer. Note: A drop of oil onthe face of the disc will provide a better contact.3. Turn the griddle temperature dials to 350°F (177°C). Inorder to allow the griddle temperatures to stabilize, thecontrols must be allowed to cycle twice before taking atest reading.4. Check the temperature reading when the control has justcycled “OFF” (as indicated by the cycling amber pilot), byplacing the sensor firmly on the griddle surface, directlyabove the sensing bulb of the control. If the temperaturedoes not read with in 8° C (15°F) of the dial setting,recalibrate as follows:5. Carefully remove the thermostat dial making sure thatthe setting is not disturbed.6. Hold the dial shaft steady and with a slim screwdriver,turn the calibration screw, located in the dial shaft,clockwise to decrease and counter clockwise to increasethe temperature. Example: 1/4 Turn = 18° C (35°F).7. Replace the thermostat dial and repeat steps 2 though 4to verify that the correct adjustment has been made.Broilers: ModelsEDU-15B, EDU-30B And EDU-42BWall ClearancesDo not install closer to a wall of combustible material than:Back: 9” (229mm)Side: 9” (229mm)Electrical SupplyBefore attempting the electrical connection, the ratingon the serial plate should be checked to ensure that theappliance electrical characteristics and the supply electricalcharacteristics agree. The electrical supply must be adequatefor the voltage, phase and current marked on the serial plate.Use only wires suitable for 90° C (194°F).The supply cable entrance is located on the front side, whenfacing the rear of the unit. The cable is fed toward the frontthrough a wire way.A knock out is provided near the front left side of the unit,located behind the control panel. To access the knockout,loosen the two acorn nuts and hinge the control paneldownwards, the terminal block is located in this area.ControlsInfinite switches (energy regulators) are used to control theelements.High to 5 High heat5 to 3 Medium heat3 to Lo Low heatSetting the switched between these numbers will giveintermediate heat. Switches are reversible and may beturned left or right.Before Operating the Broiler1. Before leaving the factory, the castings were coated withoil to prevent corrosion. Therefore, it is necessary to cleanthe castings before seasoning and cooking.2. Turn the broiler control dial/s to “HI” and allow to runempty for 15 minutes. Turn the dial/s to “OFF” and allowcastings to cool. Clean off any residue with a detergentsoaked cloth.INDIVIDUAL MODEL INSTALLATIONS continued
