9.4 CHANGING FILTER PAPER:
The top piece of filter paper should be
discarded when it becomes dark or scuffed
in appearance. Follow these procedures:
a. Before changing the paper, use the
flexible hose (with about one inch of oil
remaining in the filter pan) to flush
debris from the filter pan sides onto the
paper.
b. Return all oil to the fryer.
c. Open the hold-down ring locking
latches and lift the ring out of the filter
tank. Your unit will be equipped with
one of the types shown in figure 9-3.
d. Roll both ends of the used (top) sheet of
paper in to the center, making sure no
sediment falls out. Discard the top
sheet. Temporarily remove the bottom
sheet and set aside.
e. Remove and check the support grid for
cleanliness and scrub if necessary.
Check the filter pan for cleanliness and
scrub if necessary. Also check the
drain ports at the bottom rear of the
filter pan for sediment or blockages.
f. Replace the support grid, lay a new
filter sheet on the grid, then place the
old bottom sheet on top of the new
sheet. It is essential that two sheets of
Dean filter papers are used; use of other
than OEM parts will void the filter
warranty.
g. Replace the hold-down ring and latch
into position. Sprinkle .45kg (16oz) of
filter powder evenly across the surface
of the filter paper. Re-install the crumb
catcher (if so equipped). Then replace
the filter pan cover.
h. The unit is now ready for operation.
