1.8.2 Replacing Operating Thermostat

CAUTION

The thermostat must be calibrated after installation is complete. Refer to Section 1.7

for calibration instructions.

When handling the thermostat, do not rotate the shaft more than two turns in either

direction. Doing so will cause damage to the thermostat.

1.Disconnect the fryer from the electrical supply and drain the frypot.

2.Loosen the setscrew securing the thermostat knob and remove the knob. Remove the screws from the upper left and right corners of the control panel. The control panel is hinged at the bottom and will swing open from the top.

3.Disconnect the 9-pin connector and remove the control panel from the fryer by disengaging its tabs from the hinge slots in the mounting frame.

4.Loosen the setscrews (2) securing the flexible shaft to the thermostat shaft and slip the flexible shaft off the thermostat shaft (arrow).

5.Remove the flexible shaft guide by removing the two sheet metal screws securing it to the upper frame.

6.Disconnect the thermostat leads from pin 14 in the 20-pin terminal block and from the gas valve terminal.

NOTE: If the fryer is configured with a melt cycle, the thermostat leads will be connected to the melt cycle timer motor or PC board rather than to the terminal block and gas valve. Disconnect the leads from the motor or PC board if this is the case.

Remove setscrews (arrow) to remove flexible shaft from thermostat shaft.

7.Unscrew the thermostat from the frypot and remove.

8.Apply Loctite PST567 thread sealant or equivalent to the replacement thermostat threads.
