Accessing Fryers For Servicing - Dean D20 series Service & Parts Manual

Thermostats
Different types of thermostats are used in Decathlon Series gas fryers, depending on the fryers'
configuration.
Fryers equipped with an optional backup operating-thermostat/electronic thermostat controller: The
temperature is adjusted by changing the setting of the dial.
Fryers equipped with computer controls have a temperature probe. In this configuration, 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 1° (°F or °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 properly 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

Moving a fryer filled with cooking oil/shortening may cause spilling or splattering of
the hot liquid. Follow the draining instructions included with the fryer before
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.
