1.4Thermostats

Protector® series gas fryers have temperature probes located on the front centerline of each frypot. In this type of thermostat, the probe resistance varies directly with the temperature. That is, as the temperature rises, so does resistance, at a rate of approximately 2 ohms for every 1º F. Circuitry in the computer monitors the probe resistance and controls burner firing when the resistance exceeds or falls below programmed temperatures (setpoints).

Protector® series gas fryers are also equipped with a high-limit thermostat. In the event that the fryer fails to properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to the flash point. The high-limit thermostat acts as a normally closed power switch that opens when exposed to temperatures above 425ºF to 450ºF (218ºC to 232ºC). The different types of thermostats have different part numbers for CE and Non-CE models, and are not interchangeable.

1.5Accessing Fryers for Servicing

DANGER

Moving a fryer filled with oil may cause spilling or splattering of the hot liquid. Follow the draining instructions in Chapter 5 of the Protector® Series Gas Fryer Installation and Operation Manual (P/N 819-6339) before attempting to relocate a fryer for servicing.

1.Shut off the gas supply to the unit. Unplug the power cords. Disconnect the unit from the gas supply.

2.Remove any attached restraining devices and relocate the fryer for service accessibility.

3.After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and plug in the electrical cords.
