Maintenance Filtering

Burn Risk

To avoid burns, use PPE when filtering oil or cleaning vat.

To avoid personal injury, do not move fryer or filter pan while containing hot oil. The filter pan must be as far back under fryer as it will go, and the cover in place. Be sure the hole in the cover lines up with the drain before opening the drain.

A new filter pad should be used on the first filter of each day, but the same filter pad can be used the rest of the day, except for fish vats. After filtering a fish vat, the filter pad MUST be changed.

  1. Ensure the filter pipe is tightly connected, the filter pan is as far back under fryer as it will go, and the filter pan cover is in place. If the filter pan or cover is not in place, “CHK PAN” displays.

  2. Ensure oil is hot: The best results are obtained when the frying oil is filtered at the normal frying temperature.
