DEAN PORTABLE MICRO-FLO OIL FILTRATION SYSTEMS CHAPTER 2: IMPORTANT INFORMATION 2.1 General The MF-90 portable oil filters may be used with a variety of Dean fryers, as well as other manufacturers’ equipment. Oil capacity ranges from 65 to 172 pounds of oil, depending on the model. Length, width, height and tank depth dimensions for all units are listed in the table below. Model MF-90/65 MF-90/80 MF-90/80 LP MF-90/110 MF-90/160 MF-90/172 Unit Height (inches) 26.87 24.12 24 26.37 25.
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.
2.4 Unpacking the Filter System Ensure the container is upright. Unpack the filter carefully and 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.
DEAN PORTABLE MICRO-FLO OIL FILTRATION SYSTEMS CHAPTER 3: INSTALLATION INSTRUCTIONS 3.1 Assembling The Filter System On initial installation and before each use, remove all loose parts from the filter, wash the filter pan and all accessories in hot, soapy water and dry thoroughly. WARNING! Water or boil-out solution MUST not be allowed to drain into the filter pan or filter system. Irreversible damage will result if water is allowed into the system, and the warranty will be voided.
3.1.1 Filter Paper Configuration (cont.) D. Sprinkle 16 ounces of filter powder on the top filter sheet. Distribute the powder over the filter paper as evenly as possible. If filtering a second frypot immediately after the first, add only 8 ounces of filter powder for the second filtering. E. Place the crumb catcher screen (if used) in the filter pan. Allow the crumb catcher to rest on the top edges of the hold-down ring. F. Place filter pan cover onto the filter pan assembly. G.
DEAN PORTABLE MICRO-FLO OIL FILTRATION SYSTEMS CHAPTER 4: FILTER OPERATION 4.1 General The Dean Portable Filters are designed to operate primarily as an independent filter unit. Operations always start by ensuring the unit is properly plugged in, then rolling the filter to the fryer to be filtered. The filter will work directly under the fryers’ drain valves. The general layout of a generic MF90 Series Portable Filter System with major components identified is illustrated below.
4.2 Filtering Tools 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.
4.4 Changing Filter Paper (cont.) Remove and replace the paper as follows: 1. Remove filter cover. 2. Open the locking clips of the holddown ring and lift the ring out of the filter tank. 3. Roll both ends of the top filter paper into the center, making sure no sediment falls out, and discard. Remove the second sheet of filter paper and retain for re- use.
4.4 Changing Filter Paper (cont.) 4. Remove and check the support screen for cleanliness and scrub if necessary. Ensure there is no buildup of shortening around the nipple assembly. 5. Check the filter-pan for cleanliness and scrub if necessary; check the drain ports at the bottom rear of the filter pan also. Solidified shortening build-up around and in nipple-pipe assembly. 6. Replace the filter support screen and place a new sheet of filter paper on top of the screen.
4.4 Changing Filter Paper (cont.) 7. Replace the hold-down ring and secure. 8. Replace filter pan cover. 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. WARNING Do not leave filter unit unattended during the filtering operation.
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.
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.
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.
DEAN PORTABLE MICRO-FLO OIL FILTRATION SYSTEMS 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.
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.
DEAN PORTABLE MICRO-FLO OIL FILTRATION SYSTEMS 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.
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.
Filter Pump Fails To Pump Oil Filter pump fails to pump oil. If filter unit has a heater, turn heater ON and allow to heat for 20 minutes. Disconnect flexible oil return hose. Make sure it is cool before handling. Try blowing air through the hose. Can you blow air through it? No Submerge hose in very hot water, keeping the water out of the hose. Water in the hose will cause severe splattering when hot oil is circulated through the hose.
Rate Of Oil Return Slowing Rate of oil return to fryer is slowing. Is this the first fryer being filtered during this filtering session? No Check for excess sediment build-up on filter paper Disassemble unit and wipe excess sediment out of the bottom of filter pan "sump", and remove any sediment from drain ports in pick-up tube. Yes Install new filter paper.
Blockage Between Filter Pan and Flex-Hose Valve Possible blockage between filter pan bottom and flex-hose disconnect. Disconnect oil line from filter pan to pump at the pump end. Turn pump ON and allow it to operate for a few seconds to ensure it does not run backwards. Put your finger over the pump inlet. Is suction present? No Blockage is in pump or in the discharge line. Yes Pump is clear; plug is in the bottom of the filter pan or in the line from the pan to pump. Disconnect line at filter pan.
