2.1 General (cont.)

The used oil may be drained by gravity from the fryer into the filter pan, or removed from the fryer
by use of a suction/return hose, according to model. The oil is pumped back into the fryer vessel
using the same suction/return hose.

Oil or shortening is filtered through replaceable filter paper. Filter powder, which enhances the
filtering process, is distributed over the paper prior to filtering.

All units are shipped completely assembled with accessories packed inside the frypots. All units are
adjusted, tested and inspected at the factory before shipment.

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 the aspects of

oil filtration, and draining/cleaning procedures.

A 7-amp (115V-domestic), or 5-amp (230V-international) circuit breaker installed on the filter unit
switches the power OFF if an overload occurs.

NOTE: If the circuit breaker is triggered, depress the reset button to activate the circuit after the

failure has been detected and repaired.

2.2 Rating Plate

Information on the rating plate includes model and serial numbers, as well as electrical requirements.
Have the rating plate information handy when communicating with the factory about a unit or
requesting special parts or information. Without this information, proper identification of the unit
cannot be confirmed.

2.3 Pre-Installation

NOTE: Failure to use qualified service personnel will void the Dean warranty.

A. Standards: Use of this filter unit must be in accordance with all applicable state and local

codes.

B. Electrical Connections: Domestic MF90 filter units require a 115V 60 Hz., 15 amp electrical

supply. Units are equipped with a grounded male receptacle for use with a flexible six-foot,
16-3 SJT power cord set. If an extension cord is required, it must be a three-conductor,
grounded power cord of at least 16 gauge.

2-2

2.4 Unpacking the Filter System

Ensure the container is upright. Unpack the filter carefully a nd remove all accessories from the
carton. Do not discard or misplace parts and/or accessories; they will be needed. Any
accessories or starter kits included with the unit will be packaged inside the filter tank 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 dealer
or end-user.

If your equipment arrives damaged:
a. File claim for damages immediately – Regardless of extent of damage.
b. Visible loss or damage – Be sure this is noted on the freight bill or express receipt and is

signed by the person making the delivery.

c. Concealed loss or damage – If damage is unnoticed until equipment is unpacked, notify

freight company or carrier immediately, and file a concealed damage claim. This should be
done within 15 days of date of delivery. Retain the shipping container for inspection.

These tools are not required, but are recommended to make the filtering task easier.
A. Measuring Cup: Used to measure eight ounces by volume of filter powder.

B. Scrub Brush: To clean sediment and residue from the filter pan and fry vessel.
C. Appropriate Clothing.

4.3 Filter Preparation

1. Position the MF-90 filter next to the fryer. Remove filter pan lid and position filter
unit under frypot drain-valve extension

2. Ensure the filter power switch is in “OFF” position prior to connecting to power
supply.

3. Plug power cord into electrical outlet. The filter unit is ready for filtering. If
equipped, turn on heater switch to allow pan to preheat. After filtering, follow
instructions in Section 4.4, Changing Filter Paper.

CAUTION

The crumb tray (if equipped) in portable filter systems must be emptied into a

fireproof container at the end of frying operations each day. Some food

particles can spontaneously combust if left soaking in certain shortening

material.

4.4 Changing Fi lter Paper

The top sheet of filter paper should be replaced
after each filter session, and most certainly at the
beginning of each workday. If filter paper is
replaced once per day, excess sediment should
be scraped from the top filter paper after each
frypot is filtered (see photo). Filter at closing if
possible. This ensures the oil/shortening is at
proper filtering temperature.

4.5 Unit Operation

1. When filtering, follow these steps:

2. Follow the appropriate Sections 4.3 and 4.4 to prepare your filter for operation.

3. Then position filter under fryer drain valve extension for gravity drain, or near the fryer if
the unit is an “AU” unit.

4. Turn the fryer main power switch to the “OFF” position.

Do not leave filter unit unattended during the filtering operation. Pressurized

oil moving through the lines can cause the flexible return hose and wand

assembly to pop loose and leak hot oil.

Avoid spilling hot oil onto floor surfaces. Never drain more than the maximum

4.5 Unit Operation (cont.)

6. Open the fryer door and ensure the filter is in the proper position under the fryer drain
valve extension. Lock rear casters to prevent filter movement during the filtering
process.

WARNING

The oil temperature of the fryer to be filtered should be approximately 350°F

(175°C). Position drain handles properly prior to operating the filter unit.

Failure to do this can result in burn injury to the user.

7. Open the drain-valve and allow the fry
vessel oil to drain into the filter pan.

4.5 Unit Operation (cont.)

8. With oil return nozzle in the vessel, turn

filter switch “ON” to begin pumping
clean oil into the fryer. Allow the oil to
recycle through the fryer for a few
seconds to wash out sediment on the
bottom of the cooking vessel before
closing the drain valve.

9. Close the drain valve handle. It takes

approximately 5 to 7 minutes for the filter
to pump all the oil back into the fryer.

10. Allow the pump to run for 10-15 seconds

after air starts to flow through the wand,
before shutting off the filter. Clearing
residual shortening/oil from the return
lines reduces the likelihood of clogged
lines.

Operating the fryer without oil in the fryer vessel will cause damage to the

CAUTION

fryer and the warranty will be voided.

4-7

4.5 Unit Operation (cont.)

NOTE: After filtering, scrape off debris and sediment accumulated on the filter paper and

discard.

CAUTION

If using solid shortening, the return hose must be completely drained after

filtering, or the shortening will solidify and plug the hose or oil return lines as

it cools.

NOTE: If filtration operations problems are encountered during use, please refer to

Chapter 6 in this manual.

CHAPTER 5: CLEANING AND MAINTENANCE

5.1 General

Cleaning operations fall into three general categories:

?? Wiping unit clean after each filter session;
?? Cleaning, changing filter paper and preparing the unit for the next day’s business.
?? Weekly cleaning to remove oil deposits and other particles that were previously

missed.

WARNING

Do not use water jets to clean this equipment.

CAUTION

Never operate the filter unit unless cooking oil is at operating temperature.

5.2 Each Filter Use

Every time your Portable Filter System is used:

?? Wash down the insides of the filter pan with hot oil.
?? Change the top filter paper sheet after each filter session or at the end of the day.

Scrape sediment from the top sheet after each frypot is filtered within a filter session.

?? Wipe up any oil which may have splashed or spilled.
?? Wipe all exterior surfaces of the filter unit.

CAUTION

Do not run water or boil -out solution through the filtration system. Doing so

will cause irreparable damage to the pump, and the warranty will be voided.

5-1

5.3 Daily- Close Of Business

At the close of a working day, the last order of business should be to filter the oil in all fryers.
When the last fryer is finished, follow these steps:

1. Ensure 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.

2. Remove the filter pan cover and hold-down ring assembly, then remove the filter

paper and filter support screen.

3. Discard the top filter paper sheet and retain bottom filter paper sheet for re-use.

4. Wash all filter components with soapy water and rinse.

5. Dry all filter parts and filter pan thoroughly before reassembling.

6. Check all fittings at the rear of the filter unit; ensure that all fittings are properly

tightened.

CAUTION

The crumb tray in portable filter systems must be emptied into a fireproof

container at the end of frying operations each day. Some food particles can

spontaneously combust if left soaking in certain shortening material.

5.4 Weekly

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

?? Wash the filter pan with hot, soapy water and a brush. Dry and reassemble with new

filter paper.

?? Clean thoroughly under, around, and behind the fryers and filtering area.
?? Do not operate motor/pump until all traces of water have been removed from the

pan. Under no circumstances should water or boil-out solution be allowed to enter
the pump housing.

?? Check the connections of the inlet lines and tighten if lines become loose or start to

leak oil.

CHAPTER 6: TROUBLESHOOTING

6.1 Operating Problems

Plugged lines and plugged filter paper account for over 90% of filtration system
malfunctions. Troubleshooting flowcharts included in this chapter, provide step-by-step
instructions to assist the operator in diagnosing common malfunctions.

A. Plugged Lines

1. If solid shortening is used, and the portable filter is operated improperly, the motor
may deactivate before hot shortening is completely pumped back into the fryer.
Solidification of shortening in the lines will occur as the shortening cools. It is very
important to pump all hot shortening out of the lines to prevent plugging.

2. Hot oil/shortening drains from the frypot into the filter pan, then 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 the pump, oil returns to the fryer
through the flexible oil return hose.

3. A solid-shortening plug can exist anywhere in this path; locate the plug using the
procedures found in the flowcharts at the end of this chapter

4. To guard against plugged lines when using solid shortening, follow these guidelines:
a. At the end of the filtering cycle, let the filter bubble into the fryer through the

flexible hose for about 10-15 seconds. If it is blowing bubbles, air is moving

through the lines and the filter is less likely to be plugged.
b. If your filter is equipped with a pan heater, use it each time before you filter.
c. When pumping hot shortening back into the fryer, tilt the filter machine to the

rear for about ten seconds at the end of the filtering cycle. This will remove

about three cups of hot shortening remaining in the bottom port area.
d. When filtering is completed, disconnect the flexible line and drain any

remaining shortening from the line.

B. Plugged Paper

Improper use of the filter pre-coat powder will cause a slow oil flow return rate. The first
indication of paper plugging is a surging, jerking movement of the hose. To correct this,
review the instructions for the correct use of filter powders, and change the filter paper more
frequently. When filtering several fryers prior to changing paper, ensure that excess
sediment is scraped off the filter paper after filtering each frypot. If plugged paper remains a
problem, review the following flowcharts for proper diagnosis.

6-1

6.2 Troubleshooting Flowcharts

The following flowcharts contain information to assist the user in diagnosing the most
common malfunctions with portable filtration systems. Possible solutions and/or corrective
actions are given for each scenario.

When utilizing these flowcharts, begin at the top of the diagram, then follow each step in
sequence. Follow the arrows directing you through the sequence of steps, until you find the
cause of the problem. If the malfunction cannot be diagnosed using the flowcharts, contact
your Factory Authorized Service Agent for repairs.

DANGER

Use extreme care when working with or during electrical circuit tests. Live

circuits will be exposed.

DANGER

Inspection, testing and repair of gas or electrical equipment should be

performed by qualified personnel.
