Filtering

With prolonged use, the flashpoint of oil is reduced.

To avoid personal injury or property damage, do not use oil that is foaming or shows signs of excessive smoking.

Drain the oil at 250° F (121° C) 275° F (135° C) or less. The higher temperatures cause cracklings to burn on the steel vat surfaces after the oil has drained.

Filtering prolongs the life of the oil, the unit, as well as improves product quality. There are various ways to filter the oil. As an example, a quick filter automatically runs between cook cycles to clean the oil and remove debris from the vat. A daily filter is run at the end of the day to thoroughly clean the unit. A polish is a prolonged filtration cycle used to extend the useful life of the oil. This section explains how to access and navigate the filtration menus.

Filter Menus

  1. Press and hold the Menu button until *MAIN* displays. Refer to Main Menu.

  2. Select 1. FILTER from the menu. Menu options display.

  3. Push the Menu button repeatedly to access additional menus.

Quick Filter

The 1. QUICK option allows operators to perform a quick filter of the oil on-demand. A quick filter runs automatically after a set amount of cook cycles. Arrows pointing up and down with a sequence of tracing light displays.

Select 1. QUICK FILTER. A confirm prompt displays. If the operator selects:

  • NO x, the display returns to the previous menu.

  • YES, the drain opens automatically and the oil begins filtering.

    After a few moments, the drain closes and the oil returns to the vat. When the vat is close to full, the control panel chirps and a display timer starts counting down.

    If the unit does not detect the oil returning to the vat and displays IS POT FILLED?, check the oil level to confirm the vat is full. If the oil is:

    • Level with the hot fill line on the back of the vat, press YES.

    • Not level with the hot fill line on the back of the vat, press NO x. The filter pump motor runs for an additional 30 seconds and pumps oil from the drain pan.

Daily Filter

The 2. DAILY option allows operators to perform a daily filter of the oil and a wash cycle, if desired. This filter cycle drains the oil from the vat completely enabling the user to clean the crumbs out of the vat and wash them down the drain. The crumb catcher in the drain pan holds the debris and the filter cleans the oil.

  1. Select 2. DAILY. A confirm prompt displays. If the operator selects:

    • NO x, the display returns to the previous menu.

    • YES, the drain opens automatically and the oil begins draining. As the oil drains a brush symbol displays. Then three prompts display: FILL, WASH, DRAIN.

      The control attempts to detect when the pot does not empty properly. The control monitors the main temperature probe, and looks for it to begin cooling at a predetermined rate, as evidence that the oil has drained down below the probe and the probe is now air cooling. If by the end of the initial -Draining- step, the control has not detected sufficient temperature cooling on the main temperature probe, the control activates a display that graphically represents a blocked drain, and displays the messages DRAIN BLOCKED?, CLEAR THE DRAIN. The display continues until the expected cooling rate is observed on the main probe, or until the operator presses a button to acknowledge the message.

  2. Select the WASH option and the wash cycle begins, WASHING displays. Once completed, the display returns to the previous menu. Press STOP at any time to discontinue wash.

  3. Press FILL to return the filtered oil to the vat. After a few moments, the drain closes and the oil returns to the vat. When the vat is close to full, the control panel chirps and a display timer starts counting down. Press STOP at any time to discontinue fill.

  4. If the unit does not detect the oil returning to the vat or if the vat sensor detects the oil is below the full line the message IS POT FILLED? displays. Check the oil level to confirm the vat is full. If the oil is:

    • Level with the hot fill line on the back of the vat, press YES.

    • Not level with the hot fill line on the back of the vat, press NO x and the filter pump motor runs for an additional 30 seconds.

  5. Press X, and Polish, Back, Exit displays.

Polish

The 3. POLISH option extends the usable life of the oil by removing debris through an extended polishing (filtration) process.

An automatic polish to help increase the life of the oil automatically occurs during the morning start-up, after every cook cycle, and during the daily filter.

To manually start a polish, do the following:

  1. Press 3. POLISH. A confirm prompt displays. If the operator selects:

    • NO x, the display returns to the previous menu.

    • YES, the drain opens automatically and the oil begins draining. Downward pointing arrows display indicating the vat is draining.

    A 155 minute timer displays and starts. The oil cycles repeatedly through the drain pan filtration system until the timer expires, ultra cleaning the oil, also referred to as a polish.

    When the polish cycle completes, the display indicates that the oil is returning to the vat. The control panel chirps and a timer starts. Once the timer counts down, FILLED? displays.

    If the unit does not detect the oil returning to the vat or if the vat sensor detects the oil is below the full line the message IS POT FILLED? displays. Check the oil level to confirm the vat is full.

  2. If the oil is:

    • Level with the hot fill line on the back of the vat, press YES.

    • Not level with the hot fill line on the back of the vat, press NO x and the filter pump motor runs for an additional 30 seconds.
