24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES

Safety Components

All 24G Series Flatbottom 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 435°F [(224°C)- Non-CE]. CE and non-CE high-limits are not interchangeable.

Frying systems with built-in filtration are equipped with drain microswitches that disable the fryer if the drain valves are not completely closed. Opening a drain valve (i.e. filtering or draining the fryer) automatically opens the reset switch circuit. The drain valve must be fully closed prior to resetting the safety switch.

1.2 Accessing Fryers for Servicing

DANGER

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

attempting to relocate a fryer for servicing.

NOTE: Perform the following only if the fryer cannot be serviced in its installed location. Some of the following service procedures require the fryer to be connected to the gas and/or electrical supply.

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.
