9. PORTABLE FILTER OPERATIONS
9.1 GENERAL:
a.
These instructions are not intended to
replace the operating instructions that
came with your Dean Filter System.
They are intended to provide general
information about filtration procedures
and serve as a quick reference guide.
b.
For consistent product quality,
convenience and long-term savings, use
a high-quality liquid frying compound.
c.
The frying compound should be filtered
at least daily or even more frequently if
cooking is heavy. This ensures the
longest life possible for the frying
compound, gives better taste to the food
being prepared, and minimizes flavors
being transferred from batch to batch.
d.
When completing a filter cycle, always
close the return valve(s) at the fryer(s)
to avoid siphoning oil out of the fryer
into the filter and open the valve at the
filter to promote draining of the return
lines into the filter pan.
e.
If using solid shortening, always make
sure the return lines are clear before
turning off the filter motor and hang
any flexible lines up to drain. Solid
shortening will solidify as it cools and
clog the lines.

a. Turn the fryer “OFF”.
b. Remove the filter pan cover.
c. Remove the crumb screen (if provided) and
clean.
d. Remove the hold-down ring and clean.
e. Examine the filter paper, if it is dark or
scuffed in appearance, discard it. Follow
procedures listed in Section 9.4 to change
dirty filter paper.
f.
Remove the filter support grid and clean.
g. Remove the filter pan and clean with hot
water, then re-install. Make sure all residual
water is removed and the filter pan is dry.
Any remaining water will cause dangerous
splattering of hot oil when filtering.
h. Re-install filter support grid. Place two
sheets of filter paper on top of the support
grid. Push paper to the filter pan bottom
with the hold-down ring. Latch the hold-
down ring into place.
i.
Then reinstall the crumb catcher (if
