DECATHLON SERIES GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES

Thermostats
Different types of thermostats are used in Decathlon Series gas fryers, depending on fryer
configuration.
Fryers equipped with an optional backup operating-thermostat and/or Thermatron use a dial to
adjust temperature. In this configuration, the probe resistance varies directly with the temperature.
As the temperature rises, resistance decreases at a rate of approximately 2 ohms for every 1°F
(approximately 3.7 ohms for every 1°C).
Fryers equipped with computer controls have a temperature probe. In this configuration, the probe
resistance varies directly with the temperature. As the temperature rises, resistance increases at a
rate of approximately 2 ohms for every 1°F (approximately 3.7 ohms for every 1°C). Circuitry in the
computer monitors the probe resistance and controls burner firing when the resistance exceeds or
falls below programmed temperatures (setpoints). The temperatures are programmed by means of a
keypad on the face of the computer.
All Decathlon Series gas fryers are equipped with a high-limit thermostat. In the event that the fryer
fails to control the oil temperature, the high-limit thermostat prevents the fryer from overheating to
flash point. The high-limit thermostat acts as a normally closed power switch that opens when
exposed to temperatures above 410°F/210°C (CE) to 450°F/232°C (non-CE). CE and non-CE high-
limits are not interchangeable.
1.2 Accessing Fryers for Servicing
DANGER
Moving a fryer filled with cooking oil may cause spilling or splattering of the hot
liquid. Follow the draining instructions included with the fryer before attempting to
relocate a fryer for servicing.
1. Shut off the gas supply to the unit. Unplug the power cords. Remove any attached restraining
devices.
2. Disconnect the unit from the gas supply.
3. Relocate the fryer for service accessibility.
4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and
plug in the electrical cords.
DANGER
No structural material on the fryer should be altered or removed to accommodate
placement of the fryer under a hood. Questions? Call the Frymaster Dean Service
