Subject & Models Affected

Subject: 8263837, 8263870 and 8263838 FQ4000 FQLink Installation Instructions

Models affected: Taco Bell FilterQuick 4000 (Touch Screen) Fryers

Date: 8.29.2025

STEP 1: CONFIRM COMMON CONTROLLER IS INSTALLED

1. The fryer MUST have at least ONE (1) Common Controller (see Figure 1) installed in the battery. It must be located in the far-left Vat #1 position.
2. If a Common Controller is installed in the far-left Vat #1 position, continue to step 2.
3. The Common Controller can be identified by the large silver metal bezel that surrounds the touch screen.
4. If the fryer DOES NOT have a Common Controller installed, DO NOT PROCEED. A Taco Bell controller conversion kit 8263741 will need to be installed in the far-left vat #1 position prior to continuing to STEP 2 for installation.

Figure 1: Image showing a fryer controller with a touch screen and a prominent silver metal bezel.

STEP 2: UPDATE THE FRYER SOFTWARE

? NOTE: This step can be skipped if the fryer software was updated before the NEW Common Controller was installed.

1. Locate the USB with the FRYER SOFTWARE FILES 8122629 or 8122689 (refer to page 5 for the correct software matrix) and follow the enclosed instructions to update the fryer software using the USB port on the FAR-LEFT side of the fryer, just inside the left fryer door (see Figure 2).
2. The software versions after update should be: UIC – 20.00.176; FIB – 20.00.070

Figure 2: Image showing the USB port location on the fryer.

STEP 3: DISCONNECT KCCM & RELOCATE MODEM (IF INSTALLED)

1. Disconnect power from the fryer.
2. For 30lb fryers, open the FAR-RIGHT door of the fryer or the door with the oil reservoir (it may be the third door from the left in 4 vat fryers or larger) (see Figure 3).

Figure 3: Image of a fryer door, possibly showing the oil reservoir.

3. Remove the JIB/BIB to access the FIB box (see Figure 3). Note: The appearance of the FIB box may differ depending on date of manufacture.
4. Remove the FIB box cover by removing the two (2) ¼” screws attaching the cover and lifting on the cover to remove (see Figure 5). This box may vary by date of manufacture.

Figure 5: Image showing the FIB box and arrows indicating screw removal for the cover.

5. The KCCM board is located on the right side or rear of the FIB box (see Figure 6) depending on date of manufacture. Prior to starting, disconnecting the J1 harness may provide easier access to the RJ connectors on the FIB board (see Figure 6 & 6A).

Figure 6: Image showing the internal components of the FIB box with the KCCM board highlighted.

Figure 6A: Close-up view of RJ connectors.

6. Disconnect the RJ11 KCCM CAN/power harness (see Figure 7) from the FIB board.

Figure 7: Image of the RJ11 KCCM CAN/power harness connector.

7. Disconnect the white & black wires from the harness in the previous step from the Wago snap connectors (see Figure 8 & 9).

Figure 8 & 9: Images showing Wago snap connectors.

8. Cut or disconnect the green ground wire of the harness from the box (see Figure 10).

Figure 10: Image showing the green ground wire connection.

9. If a cellular modem is NOT CONNECTED to the KCCM board, skip to step 10. If a modem is connected, disconnect the cellular modem USB cable from the KCCM board (see Figure 11).

Figure 11: Image showing a cellular modem USB cable connected to the KCCM board.

10. Disconnect the RJ45 connector from the KCCM board (see Figure 12). Discard the complete harness, it will no longer be used. The KCCM board will remain in the box.

Figure 12: Image showing the RJ45 connector.

11. Connect the supplied RJ11 CAN terminator to the connector on the FIB board from step 6 above (see Figure 13). Reconnect the J1 connector to the FIB board if disconnected.

Figure 13: Image showing the RJ11 CAN terminator connected to the FIB board.

Continuing Installation Steps

1. If connecting using [Ethernet], route the ethernet cable to the rear of the Vat #1 controller ethernet connection and connect to the controller (see Figure 14).

Figure 14: Image showing an Ethernet cable being connected to a controller.

13. Reattach the controller.
14. Ensure the new controller is installed on the left side fryer. Follow instructions on 8197989TB if necessary.
15. After installing the controller and power cycling for 60 seconds using the master power switch (see Figure 15), wait 4 (four) minutes before proceeding to the next step.

2. On the left screen, press ⚙️ SERVICE ⚙️ -> 3000 -> ? TECH MODES -> ? SOFTWARE UPGRADE.
3. Locate the USB with the IoT AGENT SOFTWARE FILES 8122682 and insert the USB drive into the USB port on the FAR-LEFT side of the fryer, just inside the left fryer door (see Figure 17). The USB port may differ in appearance based on date of manufacture.

Figure 17: Image showing the USB port on the fryer.

4. Follow the onscreen instructions.
5. Press ✔️ YES when the screen displays READING COMPLETED.
6. Press ✔️ YES when the screen displays ALLOW 30 MINUTES FOR SOFTWARE UPGRADE. NO FRYING. UPDATE NOW? ?
7. While updating, the controller displays various messages. Once the update is finished, it will either reboot the left controller (if deploying for the first time) or display instructions to remove USB and power cycle. The right controller may still have messages showing it's updating, but it is finished. As long as the left controller displays REMOVE USB & POWER CYCLE, advance to step 8.
8. Remove the USB flash drive and lower cover over the USB slot.
9. Press ✔️ YES button to confirm.

7. The GATEWAY CONNECTION STATUS should be CONNECTED. If not, wait 5 minutes and recheck starting with step 1 on the previous page.

Figure 31: Image showing Gateway connection status and IP address.

8. The GATEWAY IP ADDRESS is shown. The GATEWAY SOFTWARE IP ADDRESS should have some numbers that are NOT ALL ZEROS (see Figure 31). NOTE: The IP address WILL be different than shown (see Figure 31). If only zeros are shown, power cycle the entire fryer battery and wait 5-10 minutes before checking the software version and IP address again. NOTE: An IP address should NOT start with 4 or 82. If so, then it is not connected. If it is NOT connected, repeat steps 1-7 of this section. If after two tries of loading the software and the version above is NOT displayed, go to STEP 5 (Troubleshooting) on the last page.
9. Press the [down arrow] button (see Figure 31).
10. View the Gateway signal strength (see Figure 32). It should show a strength of 1/5 to 4/5. The higher the number the better. If it displays 0/5, it does NOT have a connection to cell or Wi-Fi service. See item #2 on page 8.

Figure 32: Image showing Gateway signal strength display.

11. Confirm the IP address matches with what the router displays.
12. Press the “HOME” button (see Figure 26) when finished.

STEP 3: CONFIRM THE UNIT APPEARS IN THE CLOUD

1. Confirm that the unit appears online in the cloud.

STEP 4: VERIFY DATA IN THE CLOUD

1. Perform a cook on the fryer.
2. Perform a filter on the fryer.
3. Confirm that the cloud displays the proper cooks and filters performed on the fryer.

STEP 5: TROUBLESHOOTING

1. If the software version is all zeros (0), WAIT AN ADDITIONAL FIVE (5) MINUTES and recheck using steps 1-7 in STEP 2 (Confirm the IP address).

Figure 33: Image showing Gateway Signal Strength.

2. The first number on gateway signal strength (refer to Figure 33) (Gateway Signal Strength Quality) which is shown at 4/5. Below is breakdown of first number:
3. a. 4 = Excellent signal; always associated; lightning fast.
4. b. 3 = Good signal; always associated; very fast.
5. c. 2 = Fair signal; always associated; usually fast.
6. d. 1 = Poor signal; mostly associated; mostly slow.
7. e. 0 = No signal; not associated; no go.

3. If the IP address is not being displayed but the signal strength is good, then the router or the cloud may have some issues and/or configuration needs to be confirmed for accuracy and updated again.
