MF90 SERIES PORTABLE FILTRATION SYSTEMS

5.3 Daily- Close Of Business

At the close of a working day, filter the oil in all fryers. When the last fryer is finished, follow these
steps:
1. Ensure the flexible hose and pump lines are clear by running the filter pump for an
additional 10–15 seconds after air bubbles start coming from the oil return line. Then drain
the flexible hose.
2. Remove the filter pan cover and hold-down ring assembly, then remove the filter paper and
filter paper support screen.
3. Discard filter paper.
4. Wash all filter components with soapy water and rinse.
5. Dry all filter parts and filter pan thoroughly before reassembling.
6. Check all fittings at the rear of the filter unit; ensure that all fittings are properly tightened
and no leaks are present.
The crumb tray (if applicable) in portable filter systems must be emptied into a
fireproof container at the end of frying operations each day. Some food particles
can spontaneously combust if left soaking in certain shortening material.

5.4 Weekly

Follow the same procedure as for "Daily", with these additional steps:
•
Wash the filter pan with hot, soapy water and a suitable brush. Dry and reassemble with
new filter paper (1 sheet).
•
Clean thoroughly under, around, and behind the fryers and filtering area.
•
Do not operate motor/pump until all traces of water have been removed from the pan.
Under no circumstances should water or boil-out solution be allowed to enter the pump
housing.
•
Check the connections of the inlet lines and tighten if lines become loose or start to leak oil.
