MAINTENANCE AND CLEANING
Regular servicing by a competent person is recommended to ensure the continued safe and efficient performance of the appliance.
Thermostat Calibration
WARNING: Turn off the electrical mains before commencing any service work.
It is normal for an electromechanical thermostat to cycle with a 45° F - 50°F (25°C - 28°C). When checking calibration, allow the thermostat to cycle a minimum of two times.
1.Place the thermocouple of the test instrument in the center of the tank 1” (25mm) below the oil surface.
2.Turn the thermostat dial to 325° F (163° C). In order to allow the oil temperature to stabilize, the control must be allowed to cycle twice before taking a test reading.
3.Check the temperature reading just when the control cycles “OFF” as indicated by the cycle pilot lamp. If the temperature does not read within 15°F (8°C) of the dial setting, recalibrate as follows:
4.Carefully remove the thermostat dial, not disturbing the dial setting.
5.Hold the thermostat shaft steady and with a small flat blade screw driver, turn the calibration screw located inside the shaft clockwise to decrease the temperature and counter clock wise to increase the temperature. NOTE: Each 1/4 turn of the screwdriver will create a change of approximately 35° F (20° C).
6.Replace the thermostat dial and repeat steps 1 through 3 to verify that correct adjustment has been made.
REPLACEMENT OF PARTS
WARNING: Turn off the electrical mains before commencing any servicing work.
Thermostat
1.Remove the screws securing the front panel to the front rail and drop the panel.
2.Disconnect the wires from the taps on the thermostat.
3.Remove the dial from the thermostat and the screws securing the thermostat body to the control panel
4.Remove the wires from the thermostat terminals. Be sure to note which wire connects to which terminal on the thermostat.
5.Remove the thermostat sense bulb. Note the path of the capillary and install the new one in the same manner.
6.Replace the faulty thermostat and reassemble in the reverse order.
Indicator Lamps
1.Remove the screws securing the front panel to the front rail and drop the panel.
2.Disconnect the supply wires to the lamp body and remove the faulty lamp.
3.Reassemble in the reverse order.
Heating Elements
1.Tilt rotating element head up and remove the element terminal cover.
2.Disconnect the supply wires to the element.
3.Remove the sealing connectors.
4.Reassemble in the reverse order replacing the sealing connectors.
