9.3 FILTER OPERATION:
Dean MF-90 Portable Filter Systems are
designed to return the filtered oil by means
of a flexible oil return hose which connects
to the filter’s quick disconnect. The
operator uses a wand connected to the end
of the flexible oil return hose to direct
filtered oil into the fryer vessel from above.
Filter operations always start with making
sure the unit is properly plugged in, then
rolling the filter to the fryer to be filtered.
The filter works directly under the fryer's
drain valve.
a. Open the drain valve by pulling the
handle out. The oil will transfer from
the fryer vessel to the filter pan.
b. Turn the filter switch to the “ON”
position on the filter control panel to
begin pumping oil into fryer. If your
filter unit is equipped with a flexible
hose/nozzle, ensure nozzle is positioned
to return oil safely into the fryer vessel.
c. When oil and fryer vessel are clean,
close the drain valve. It takes the filter
approximately 5 to 7 minutes to pump
all oil back into the fryer. Run the filter
pump an additional 10-15 seconds after
bubbles appear in oil to clear oil return
lines.
d. Make sure the drain valve is fully
closed.
