2. Remove the filter pan from the unit and drain one frypot at a time into a Shortening Disposal Unit (SDU) or
other appropriate metal container using the drain function on the MIB board (see section 1.14 on page 29).
DANGER
DO NOT
attempt to drain more than one full frypot or two split frypots into the SDU at
one time.
3. Dismount the topcap by removing the screws on the bottom of each front corner and lifting the topcap
straight up.
4. Remove the bezels by lifting them up to disengage the tabs along the lower edges from the slots in the
control panel frame. Remove the top screws in the upper corners of the controller.
5. Grasp the upper edge of each controller and swing the controller downward. Unplug the controller wiring
harness and grounding wire from the back of each controller.
6. Remove the controllers by lifting them from the hinge slots in the control panel frame.
7. Disconnect the sound device wire from the interface board.
8. Disconnect the flame sensor wires by carefully pulling the push-on terminals from the terminal strips on the
ignitors. Disconnect the gas enrichment tube at the ignitor-end compression fitting. Disconnect the ignition
cables from the ignitors by grasping the boots and gently pulling toward you.
9. Remove the two mounting screws on each side of the component box and rotate the top of the box out of
the frame. Carefully pull it out enough to disconnect the wiring harness connector from the back of the
box. Cut any ties that prevent the box from being pulled out of the control panel frame.
10. Carefully pull the box clear of the frame and rest it on top of the fryer.
11. Using a pin pusher, remove the temperature probe, high-limit thermostat wires and RTD probe wires from
the plugs or terminals, marking each wire to facilitate re-assembly.
12. Disconnect the actuators from the return and drain valves.
13. Remove the section(s) of drain from the drain valve(s) of the frypot to be removed.
14. Disconnect the gas lines from the burner orifices and ignitor assemblies.
15.
Remove the frypot hold down bracket
.
16. Remove the screws in the back panel and inside the flue cap at each end that secure the flue cap to the fryer
and lift it clear of the fryer.
17. Disconnect the oil return line(s) from the frypot to be removed.
18. Disconnect all wiring from the AIF board.
19. Carefully lift the frypot from the fryer cabinet.
20. Remove the drain valve(s), temperature probe(s), high-limit thermostat(s), RTD probes, oil level sensor
probes, AIF boards, actuators and ignitor assemblies. Inspect each of these components carefully and
install them in the replacement frypot if they are in serviceable condition. Use Loctite
®
PST56765 sealant
or equivalent on component threads.
NOTE:
Some servicers, based upon their experience, recommend that probes and thermostats be replaced
whenever a frypot is replaced; however, this remains the customer’s decision.
21. Reverse steps 1-20 to reassemble fryer.
NOTE:
Care should be taken not to over-torque nuts on frypots made of 400-series stainless steel, as this
could tear the material. One turn past hand-tight is sufficient torque.
22. Perform steps 14 through 18 of Section 1.9.9 to ensure that there are no leaks in the burner insulation.
CAUTION
Before installing temperature probes, high-limit thermostats, RTD probes, oil level
sensor probes, return valves and drain valves on replacement frypot, clean the
threads and apply Loctite
®
PST56765 thread sealant or equivalent.
