B. Filtering Process ‐
9. Complete the filtering procedure as follows.
• In the lower cabinet of the unit being filtered, place the OIL RETURN valve handle ⑥
to the [FILL POT] position
• Ensure the OIL WAND handle ⑤ and WASTE OIL handle ⑦ (if equipped) are in the
[CLOSE] position (on banked units, these valves are located in the main unit with
filter pan).
• On the unit being filtered ... Slowly move the DRAIN valve
handle ⑧ to the [OPEN] position (fully right to a stop).
Oil should begin draining from vat. If oil does not readily
drain, use the provided round‐bristle Drain Brush to break up
residue that might be blocking the vat drain
.
• After the majority of used oil has drained into the filter
pan, place Pump Switch ⑨ on control panel in the
[PUMP] position (on banked systems, switch is located on
the unit with filter pan).
• Filter pump will start, drawing oil through the filter media and pumping it back into the cook vat. Leave the
drain valve open and allow oil to continually recirculate as a “crumb wash” to flush crumbs and residue into the
filter pan. During this time use the provided soft‐bristle, heat‐resistant Pot Brush and round‐bristle Element
Brush to clean residue from vat sides and heating elements, allowing it to be flushed out of the vat.
• After 3 to 5 minutes, slowly return the DRAIN valve handle ⑧ to the [CLOSE] position (fully left to a stop) and
allow the vat to refill with filtered/reconditioned cooking oil.
• When vat has filled and no more oil is being discharged from the oil return fitting, return Pump Switch ⑨ to
the [OFF] position, and then return the OIL RETURN valve ⑥ to the [CLOSE] position.
• Visually confirm that oil level is satisfactorily between the [ADD] & [FULL] level marks. Add fresh oil as needed.
If Top‐Off option is installed, refer to Section 4.03, Oil Top‐Off, .
• Press the [CLEAR] key to return fryer to PREHEAT mode and place the Heat Switch ③ in the [HEAT] position to
begin reheating oil to set cooking temperature.

Always wear thermal protection when performing this step. Parts can be excessively hot!
10. After refilling vat, remove filter pan from fryer (see Step #3) and remove pan cover.
Remove the crumb screen and empty as needed. Taking care not damage the filter
media, use the provided Crumb Shovel and scoop filter sediment from the surface

cycle. As a minimum, once daily the Filter Pan should be throughly cleaned and filter
media replaced with new (refer to Section 5.03).
