2. IMPORTANT INFORMATION

2.1 GENERAL: The Micro-Flo CF-35,

CF-60, and CF-80 Cascade Oil Filters are
units with an oil capacity of 50 pounds,
60 pounds, and 110 pounds (respectively)
that fit inside the Dean Industries’
Decathlon D35G, D60G, and D80G
fryers. The Cascade Filters can be used
as portable units also.

The used oil drains by gravity from the
fryer into the filter pan and then it is
pumped back to the fryer vessel.

Filtering is accomplished through two
sheets of replaceable filter paper assisted
by a micro pre-coat filter powder.

CAUTION

The on-site supervisor is responsible for
ensuring that operators are made aware of the
inherent dangers of operating a hot oil filter
system, particularly aspects of oil filtration,
draining, and cleaning of the filter.

special parts or information, this data is
essential for proper identification.

2.5 PRE-INSTALLATION:

a. GENERAL: These filters, when

used in combination with a fryer,
require no additional space. When
used as a portable filter, it will require
an area of floor space approximately
1-1/2' x 2-1/2' (3.75 sq ft).

b. STANDARDS: Installation must be

in accordance with all applicable state
and local codes.

c. ELECTRICAL CONNECTIONS:

The filter may or may not be equipped
with a pan heater. Only one
connection is required to a
115V/60HZ 15-amp electrical supply
receptacle on the fryer. When used as
a portable filter, the 2-1/2' flexible 16­3 SJT power cord is to be connected
to a suitable extension cord.

2.2 OPERATING CONTROLS: An

“ON/OFF” switch is mounted on the
pump motor housing. If equipped with an
optional pan heater, a three (3) position
switch (HEAT/OFF/PUMP) is mounted
on the pump motor housing in lieu of the
“ON/OFF” switch.

2.3 SAFETY FEATURES: A 7-amp

circuit breaker switches the power OFF if
an overload occurs.

NOTE: IF CIRCUIT BREAKER IS
TRIGGERED, THE RESET BUTTON
NEEDS TO BE DEPRESSED TO
ACIVATE THE CIRCUIT AFTER
NATURE OF FAILURE HAS BEEN
DETECTED AND FIXED.

2.4 RATING PLATE: Information on

this plate includes the model and serial
numbers, as well as electrical
requirements. When communicating with
the factory about a unit or requesting

2.6 UNPACKING THE FILTER:

Check that the container is upright.
Unpack the filter carefully and remove all
accessories from the carton. Do not
discard or misplace these, as they will be
needed.

Loose parts include starter kit, the filter
hose and wand for portable operation and
accessories that may have been ordered.
These are packaged inside the filter tank.
The tank top is strapped to the shipping
frame.

After unpacking, immediately check the
equipment for visible signs of shipping
damage. If such damage has occurred,
contact the carrier and file the appropriate
freight claims. Do not contact the
factory, as the responsibility of shipping
damage is between the carrier and the
dealer or end-user.

Allow the pump to run for 10 – 15
seconds after air bubbles appear in the
fryer vessel before shutting off to clear
shortening/oil from the return lines.

WARNING!

THE OIL TEMPERATURE OF THE
FRYER TO BE FILTERED SHOULD BE
AROUND 350°F (175°C). AT ALL TIMES
HOLD THE FLEXIBLE HOSE NOZZLE
IN THE FRYING VESSEL OR SECURED
IN THE FILTER PAN PRIOR TO

4.6 PORTABLE FILTER
OPERATION:

Figure 4-6 shows the oil flow during
portable filter operations. Follow these
instructions for portable operations:

Turn the pump on and return the
remaining oil to the fryer.

h. When there is no more oil coming out

of the hose nozzle, allow the pump to
run an additional 10-15 seconds before
turning the pump off. This will allow
the pump to clear the oil return lines
and the hose assembly of remaining oil
or shortening.

i. Disconnect the hose nozzle assembly

and hang up the assembly to allow it to
dry.

a. Prepare a precoat/slurry per the pre-coat

manufacturer’s instructions.

b. Turn “OFF” fryer to be filtered. Pour

the mixture onto the filter pad.

c. Remove filter lid cover and position the

filter pan under the fryer drain valve,
then install drain extender. Attach
return hose.

d. Open the drain valve and drain fryer oil

into the filter. If there is an abundance
of sediment in the fryer, put a strainer
under the drain valve to remove these
particles before they get into the filter
pan. This will conserve filter paper and
shorten filtering time.

e. Hold return hose in the fryer vessel,

then turn the filter pump on. Wash all
remaining sediment from the fryer into
the filter with the hot oil return hose.

f. Shut the drain valve and return the oil

to fryer.

g. When pumping oil back into the last

fryer, turn the filter off and direct the
hose nozzle back into the filter when
about one inch of oil remains in the
filter pan. Turn the filter back on and
use this hot oil to flush sediment from
bottom corners and side walls of the
filter pan. Once finished flushing the
filter pan, turn the filter off and direct
the hose nozzle back into the fryer.

j. Remove the filter pan cover and scrape

any solid matter from the filter paper.

k. Wipe the filter pan dry with dry

toweling.

l. Replace cover onto the filter pan and

store filter unit.

4.7 OPERATING PROBLEMS:

Plugged lines and plugged filter paper
account for over ninety percent of
malfunctions. The troubleshooting
flowcharts found in Chapter 6 can provide
a step-by-step guide to correct these and
other common malfunctions.

a. PLUGGED LINES:

1. If you are using solid shortening

and the filter is operated
improperly, the motor may shut off
before the hot oil is completely
pumped back into the fryer and
solidification of the oil in the lines
could occur as the oil cools. The
illustrations in Figures 4-4 and 4-6
show the path of oil in a filter
circuit for the portable and built-in
operational modes.

2. Oil drains from the fryer vessel into

the filter pan, then it is drawn
through the filter paper, exits the
pan through the ports on the filter
pan bottom, then flows through a
rigid tube to the filter pump. From

9

the pump, oil returns to the fryer
through the flexible oil return hose
or the internally-plumbed oil return
line in the fryer.

3. A solid shortening plug can exist
anywhere in this path; locate the
plug using the procedures found in
Chapter 6, Troubleshooting Guide.

4. To guard against plugged lines when
using solid shortening, follow these
guidelines:

a. If your filter is equipped with a

pan heater, use it every time you
filter.

b. Also, at the end of the filtering

cycle, let the filter flow bubbles
into the fryer through the
flexible hose for about ten
seconds. If it is blowing
bubbles, air is moving through
the lines and they cannot be
plugged.

c. When filtering is completed,

always disconnect the flexible
line and hang it up to drain.

b. PLUGGED PAPER: Improper use of

the filter pre-coat powder will cause a
slow oil flow return rate. The filter
paper should at least be scraped (if not
discarded) after filtering a particularly
dirty fryer. First indication of paper
plugging is a surging, jerking movement
of the hose. To correct, check the
instructions for the right use of powders
and scrape the filter paper more
frequently. Also review procedures
found in Chapter 6, Troubleshooting
Guide.

10

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. And, a more thorough weekly cleaning.

5.2 EACH FILTER USE:

Every time your Cascade Filter System is
used:

a. Wash down the sides 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:

c. Remove the filter pan cover, the crumb

catcher (if equipped) and hold-down ring
assembly; then take out the paper and
protection screen.

d. Wash all of removed items with soapy

water.

e. Clean the filter pan with a dry towel.
f. Be sure that all items have been dried

thoroughly before reassembling.

5.4 WEEKLY:

Follow the same procedure as for “DAILY”,
with these additional steps:

a. Check the connections of the inlet lines.

Tighten if the inlet lines become loose or
start to leak oil.

b. Wash the filter pan with hot, soapy water

and a brush. Dry and reassemble with
new filter paper.

c. Clean thoroughly under, around, and

behind the fryers and filtering area.

d. Avoid getting water inside the

motor/pump housing when washing the
filter pan.

WARNING!

a. If used as a portable filter, run the filter

pump for an additional 10 – 15 seconds
after air bubbles come out of the filter
hose nozzle before shutting “OFF”.
Keep the filter hose pointed down into
the last fryer’s fryer vessel until done.
This should clear the hose line of any
remaining oil or shortening.

b. Remove the filter unit from the fryer.

Scrape the top piece of filter paper.
Replace filter paper if it is scuffed or
dark.

DO NOT RUN WATER THROUGH THE
FILTERING SYSTEM AS PART OF THE
CLEANING PROCESS. THE FILTER
PUMP IS NOT DESIGNED TO HANDLE
WATER. THIS WILL VOID THE
WARRANTY FOR THAT SYSTEM,
HASTEN PUMP FAILURE AND CAUSE
ACCIDENTS IF WATER MIXES WITH
HOT OIL.
