1.8Measuring Flame Current
When the burner flame is properly adjusted, it will produce a current between 2.5 μA and 3.5 μA. Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing wire on the ignitor. This is accomplished as follows:
1.Place the fryer power switch in the OFF position.
2.Disconnect the sensing wire from one of the burner ignitors and connect it to the positive lead of the meter. Connect the negative lead of the meter to the terminal from which the sensing wire was removed.

3.Place the fryer power switch in the ON position to light the burners. After the frypot temperature reaches 200°F (93°C), wait at least one minute before checking the reading. NOTE: The closer the unit is to normal operating temperature, the more accurate the reading will be.
1.9Replacing Fryer Components
1.9.1 Replacing the Computer or the Computer Wiring Harnesses
1.Disconnect the fryer from the electrical power supply.
2.The computer bezel is held in place by tabs at the top and bottom. Slide the metal bezel up to disengage the lower tabs. Then slide the bezel down to disengage the upper tabs.
3.Remove the two screws from the upper corners of the computer. The computer is hinged at the bottom and will swing open from the top.
4.Unplug the wiring harnesses from the connectors on the back of the computer (see following page) marking their position for reassembly and disconnect the grounding wires from the terminals. Remove the computer by lifting it from the hinged slots in the control panel frame.

5.Install the replacement computer. Reinstall the control panel assembly by reversing steps 1 thru 4.
6.Readdress the new CM7 computer. The readdress procedure can be performed from any one CM7 computer in the bank.
