MICRO-FLO BUILT-IN SERIES FILTRATION SYSTEMS CHAPTER 3: RECEIVING & INSTALLING THE FILTER 3.1 General Unpack the filter (or the fryer/filter combination) carefully and remove all filter parts from the carton.

Remove the filter hold-down ring, place two papers on the grid, and then replace the hold-down ring. It is essential that "Dean" filter papers are used; use of other than OEM parts will void the warranty. The remaining filter papers should be stored away from moisture for future use. - Page 8 4.2.2 Models 1994 and After See section 4.2.1 for filter pack assembly.

- Page 9 4.3.1 Models Prior to 1994 (cont.) If filter is equipped to filter solid shortening, the "On-Off" switch will be a three-position switch labeled "Pump/Off/Heat". The "Pump" position is used to operate the filter. The "Heat" position is used to melt residual shortening from previous filter operations. Do not attempt to melt a block of solid shortening with the filter heater.
- Page 10 4.3.1.2 Filter Operation A. Turn fryer "OFF". B. Filter one fryer at a time. C. Remove fry-baskets, crumb screen and/or drop-in grid from fryer. D. Stir the oil below the heat transfer tubes or electric elements with an "L" shaped Teflon brush (included with accessory pack) to loosen sediment.
- Page 11 4.3.1.2 Filter Operation (cont.) L. Allow the filter to pump bubbles into the fryer for 15-20 seconds to ensure evacuation of all oil/shortening from the filter pan and return lines. M. Turn the filter switch to "OFF". N. Close the oil return valve (or push yellow handle) to the fryer being filtered. NOTE: The filtering cycle for one fryer is complete.
- Page 12 4.3.1.3 Changing Filter Paper (cont.) F. Remove and check the grid for cleanliness and clean if necessary. G. Inspect the filter pan for cleanliness and clean if necessary; also inspect the oil-pickup tube at the rear of the pan for obstructions or solidified shortening. H.
- Page 13 4.3.2.1 Filter Paper Configuration (cont.) 3. Sprinkle 16 ounces of filter powder evenly over the filter paper. Return the filter pan to filter cabinet, ensuring that the drainpipe outlets are directly over filter pan. If filtering a second frypot immediately after the first, add only 8 ounces of filter powder for the second filtering.
- Page 14 4.3.2.2 Filter Operation (cont.) 5. Ensure the "Orange" handle in the filter cabinet is closed and turn the filter power switch "ON". Turn "Orange" handle to the right (handle end "UP") to close hose connect valve. Note: The filter circuit is protected by a 7-amp breaker located on the control panel of the filter cabinet.
- Page 15 4.3.2.2 Filter Operation (cont.) Note: Drain-Flush Line Only- If fryer being filtered is used for frying heavily breaded products, or is the last fryer in the battery, use the drain flush to flush excess sediment from the drainpipe into the filter pan.
- Page 16 4.3.2.2 Filter Operation (cont.) 12. Allow the filter to pump bubbles into the fryer for 15-20 seconds to ensure evacuation of all oil/shortening from the filter pan and return lines. 13. Close the "Yellow" oil-return valve and immediately turn the filter pump "OFF". Ensure all oil return valves are completely closed so as to prevent oil/shortening from siphoning out of the fry vessels.
- Page 17 4.5 Operating Problems Operating problems account for over 90 percent of filtration system malfunctions. If solid shortening is being used, and the filter is operated improperly, shortening solidification will occur in the lines as the shortening cools, increasing the chance for clogged lines. Micro-Flo Built-In filtration systems are equipped with an overload circuit breaker to help prevent filter motor damage in case of overload.
- Page 18 4.5.3 Plugged Filter (cont.) WARNING Never blow into filter return lines while the lines are connected to locate a plug. Never hold your hand over the outlet end of a line. A plug could unexpectedly release and spray hot oil, causing severe burns. When checking the filter pump for blockage, turn the power switch to the "Out"...
- Page 19 4.5.4 Return Lines (cont.) To prevent plugged lines when using solid shortening, adhere to the following: ø If the filter is equipped with a pan heater, use it each time a fryer is filtered. ø Allow the pump to run for 15-20 seconds after air starts to flow through the lines (or flexible hose), before shutting off the filter.
- Page 20 MICRO-FLO BUILT-IN SERIES FILTRATION SYSTEMS CHAPTER 5: CLEANING & MAINTENANCE 5.1 Each Filter Use Every time the Micro-Flo filter 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.
- Page 21 5.3 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. •...
