1.1.3 THERMOSTATS
Pro (H50/55) Series gas fryers have
temperature probes
located on the front centerline of each
frypot (dual-vat frypots have two probes, one in each vat). 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 controller 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
controller.
Pro (H50/55) Series 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 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.
1.2
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 in Chapter 4 of the Installation and Operation
manual (P/N 819-5991) before relocating 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.
