CHAPTER 2: IMPORTANT INFORMATION
2.1 General
Multi-batteried frying systems can come equipped with the Under Fryer Filter (UFF) system. Single
fryers can come equipped with the Single Under Fryer Filter (SUFF) system. Filter design varies
according to the model of the fryer/frying system.
Oil or shortening is drained from the fryer into the filter pan, then pumped back into the frypot by
means of oil-return plumbing built into the fryer.
Filtering is accomplished with one sheet of replaceable filter paper and filter powder, or by means of
a filter-leaf assembly (see photos below).
Applying filter powder to filter paper.
Optional filter-leaf used in place of filter paper.
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.
2.2 Rating Plate
Information on the rating plate includes model and serial numbers, as well as electrical requirements.

3.3 Daily Filtration Operation
WARNING
Use caution and wear proper protective clothing. The oil to be filtered is at or near
350°F (177°C). Ensure all hoses are connected properly and drain handles are in
their proper position prior to operating any switches or valves. Failure to do this can
result in severe burns.
WARNING
Drawings and photos used in this manual are intended to illustrate operational,
cleaning and technical procedures and may not conform to on-site management
operational procedures.
3.3.1 General Overview
Only filter oil at operating temperature (~350°F/~177°C). When filtering begins, the filter motor is
engaged and oil is drawn through filter paper or a filter-leaf assembly and pumped back into the
frypot. The frypot’s drain remains open during the filtering process. Allow the oil to cycle through
the filter process for approximately 5 minutes. At the end of 5 minutes, close the drain valve and
allow the pump to fill the frypot to the top OIL LEVEL line. Leave the pump running for 10-15
seconds after bubbles appear in the frypot to ensure all oil is pumped from the drain pan and the
lines.
3.3.2 Filtering Tools
Assemble tools to be used for filtering. These are supplied with the filter starter kit included with
the fryer/filter system:
•Frypot/Filter Brush - used to clean frypot and filter pan sides and bottom, heating elements,
and to dislodge sediment during filtration or oil change.
• Clean-out Rod (design may vary) - used to dislodge heavy debris in the drain tube (when needed).
• Filter Powder.
• Filter Paper (not used in filter-leaf equipped filter systems).
The following tools are not required, but are recommended to make the filtering task easier.
• Measuring Cup - used to measure filter powder.
• Stainless Steel Crumb Scoop - for removing large debris from oil prior to filtering.
Note: Always wear oil-resistant, insulated gloves and/or protective gear when
working with hot oil.

CHAPTER 3: INSTALLATION AND OPERATION
3.4.3 Hose and Wand Operation
Some frying systems come equipped with a hose/wand to facilitate the removal of debris from the
frypot. On some systems, a blue handle activates the hose/wand flush. On other systems, the quickdisconnect is under positive pressure and has no ON/OFF valve. Plugging the hose into the
disconnect activates the flush. On positive pressure systems, the oil flow can be moderated with the
oil return valve (yellow handle). On blue-handle equipped systems, adjusting both the yellow and
blue handles will moderate the oil flow. With partial pressure directed to the hose/wand, oil flows
through both the filter pan and frypot.
1. Ensure the oil is at operating temperature
(~350°F/~177°C). Turn the fryer off and
open the fryer drain valve. Allow the oil to
drain into the filter pan.
2. When all the oil has drained from the frypot,
connect the hose/wand assembly to the

CHAPTER 4: CLEANING AND MAINTENANCE
4.1 General
Cleaning operations fall into three general categories:
• Wiping unit clean after each filter session;
• Cleaning filter or filter-leaf assembly, changing filter paper (systems without filter-
leaf), and preparing the unit for the next day’s business.
• Weekly cleaning to remove oil deposits and other particles.
CAUTION
Never operate the filter unit unless cooking oil is at operating temperature.
4.2 Each Filter Use
Every time the SUFF/UFF filter system is used:
• Wash down the insides of the filter pan with hot oil.
• Change the filter paper (not applicable to filter-leaf equipped systems; see
CLEANING THE FILTER-LEAF ASSEMBLY below) after each filter session or at
the end of the day. Scrape sediment from the filter paper after each frypot is filtered
and dispose of it in a fireproof container.
• Wipe away any oil.
• Wipe all exterior surfaces of the filter unit.
CLEANING THE FILTER-LEAF ASSEMBLY
Filters equipped with a filter-leaf require specific cleaning and assembly procedures. In the
absence of cleaning and disassembly/reassembly instructions shipped with the filter-leaf, use
the following procedure (see illustration on next page):

SUFF/UFF FILTRATION SYSTEMS
CHAPTER 4: CLEANING AND MAINTENANCE
4.3 Daily (Close of Business)
At the close of a working day, oil in all fryers should be filtered. 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 into the filter pan (if equipped with a flush option).
2. Remove the filter pan cover and hold-down ring assembly (see Section 4.2 for filter-
leaf instructions), then remove the filter paper and filter support screen.
3. Discard the filter paper into a fireproof container.
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.
DANGER
The crumb tray in SUFF/UFF 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 Weekly
Follow the same procedure as for Daily (Close of Business), 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; irreparable damage will result, and all warranties will be voided.
•Check the connections of the inlet lines and tighten if lines become loose or start to
leak oil.
