Cleaning And Maintenance - Dean MF90 Series Parts Manual

5. CLEANING & MAINTENACE
5.1 GENERAL:
Cleaning operations fall into three general
categories:
a. The continuing habit of clean-up every
time the filter unit is used;
b. The daily clean-up at the close of each
business day;
c. A more thorough weekly cleaning.
5.2 EACH FILTER USE:
Every time your Portable Filter System is
used:
a. Wash down the insides of the filter pan
with hot oil.
b. Scrape and possibly change the top
sheet of filter paper. Always scrape
sediment and debris from the paper
when the system is warm; this
prolongs the life of the paper.
c. Wipe up any oil which may have
splashed or spilled.
d. Wipe all exterior surfaces of the filter
unit.
5.3 DAILY - CLOSE OF BUSINESS:
One of the last orders of business at the
close of a working day should be to filter
the oil in all fryers. When the last fryer is
finished, follow these steps:
a. Make sure 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.
b. Discard the top filter paper sheet after
use.
c. Remove the filter pan cover and hold-
down ring assembly; then take out the
paper and protection screen.
d. Wash all of removed items with soapy
water, then rinse them.
e. Dry all filter parts and filter pan
thoroughly before reassembling.
f. Check all fittings at the rear of the
filter unit as any loose fittings will
impair oil return.
Do not use a jet washer to clean this
filter unit.
5.4 WEEKLY:
Follow the same procedure as for
"DAILY", with these additional steps:
a. Wash the filter pan with hot, soapy
water and a brush.
reassemble with new filter paper.
b. Clean thoroughly under, around, and
behind the fryers and filtering area.
c. Avoid
motor/pump housing when washing
the filter pan.

THE FILTERING
PART OF

WARRANTY FOR THAT SYSTEM,
HASTEN PUMP FAILURE AND
CAUSE ACCIDENTS IF WATER
