High Limit Inspection Rev. A Nov 2016
High Limit Inspection
- 8 Head PFE and PFG Fryers
Objective: Ensure the high limit is securely installed and operational
Procedure
1. Drain oil to drain pan and visually inspect the high limit bulb and capillary tube mounted inside the fry pot.
Ensure the bulb is not dented, the capillary tube is not severed and the bracket matches figure 1. for a 690 or
figure 2. for a 580 / 590. If the capillary tube or bulb is damaged, stop. Take the fryer out of service until it is
replaced with #16738. If any hardware is damaged, or missing, replace hardware to match figures 1 and 2.

2. Press the red reset button on the high limit several times. If this button clicks each time it is pressed, stop.
Take the fryer out of service until the high limit can be replaced with part #16738 and make sure it gets wired
into the circuit upon replacement.
3.
With power disconnected from the fryer, lower the control board, remove the heat shield, and remove the two
mounting screws that secure the high limit body to the fryer. Remove the high limit and inspect to make sure
the high limit is properly wired into the circuit. Make sure both wires are
not attached to the same terminal
on the high limit. Make sure these wires are not damaged, and also make sure the two wires have not been
removed from the high limit and connected together. Figures 3 & 4 shows a properly wired high limit (690 high
limit shown). If bypassing of the high limit is found, or any damaged wiring is found, stop. Take the fryer out of
service until the wiring is corrected and high limit replaced if defective..
