CHAPTER 2: IMPORTANT INFORMATION
2-1
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).
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.
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.
Applying filter powder to filter paper. Optional filter-leaf used in place of filter paper.

2.3 Pre-installation
NOTE: Failure to use qualified service personnel will void the Dean warranty.
A. Standards: Usage of this filter unit must be in accordance with all applicable state and local
codes.
B. Electrical Connections: SUFF/UFF filter systems require connection to a 120V, 60-cycle,
15-amp power supply, or a 220V, 50-cycle, 7-amp power supply. Units are equipped with a
grounded male receptacle for use with a 3-wire, 16 AWG power-cord set. If an extension
cord is required, it must be a three-conductor, grounded power cord of at least 16 gauge.
C. Safety Features: A 5-amp (230V) or a 7-amp (115V) circuit breaker switches the power OFF
if an overload occurs. In addition, a thermal-overload circuit breaker is built into the filter
motor. If an overload occurs, allow the motor to cool for 45 minutes, then press the reset
button to reset the thermal-overload circuit.
NOTE: If the circuit breaker is triggered, depress the reset button to activate the circuit
after the failure has been detected and repaired.
2.4 Unpacking the Filter System
Ensure the container is upright. Unpack the filter carefully and remove all accessories (if
included) 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.
NOTE: Dean does not assume responsibility for damage or loss incurred in transit.

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.
3.1 General
Most SUFF/UFF systems use filter paper as the filter medium. Some filter systems can be special
ordered with a filter-leaf assembly, which eliminates the need for filter paper. Both types require the
use of filter powder to enhance the filtration process. Photos used in the procedural illustrations may
or may not resemble the filter unit that came with the frying system. The following procedures
apply to all fryers equipped with SUFF/UFF filter systems. Filter system design depends on the
frying system configuration (single or multi-batteried systems- see photos below).
Typical Under Fryer Filter (UFF) installed in a
multi-batteried frying system.
Typical Single Under Fryer Filter (SUFF)
installed in a single fryer.

3.2 Filter Preparation
On initial installation and before each use, clean the filter:
a. remove all loose parts from the filter,
b. wash the filter pan and all accessories in hot, soapy water,
c. and dry thoroughly.
3.2.1 Filter Unit Identification
Current Production
SUFF/UFF filtration systems use filter paper or a filter-leaf to remove impurities. Filter paper is
held in place by a hold-down ring.

Previous production filter units differed slightly from current production units. There were two types
of hold-down rings: the latchless or weighted hold-down ring (similar to current production) and the
latching hold-down ring.

3.2.1 Filter Unit Identification (cont.)
SUFF/UFF systems incorporating a filter-leaf assembly use a fine mesh screen to filter impurities
and debris from the oil. The oil is pumped through the screen and then returned to the frypot. The
advantages of the filter-leaf include unlimited re-use and the elimination of paper cost.
Filter pans with filter-leaf assemblies are assembled as illustrated below:
1. Filter pan with caddy assembly.
2. Compression cap and riser intake
assembly.

3.2.2 Assembling the Filter
Assembling Filter Units with Latchless Hold-down Rings
1. Place the support grid in the bottom of filter
pan.
2. Put one filter paper sheet on top of the
support grid. Be sure the paper covers the
filter pan bottom and laps two inches onto the
pan wall.
3. Position the hold-down ring on top of the
filter paper. Ensure the hold-down ring seals
around the support grid. This prevents air
from getting into the system.
Support grid properly placed in filter pan.
Ensure filter paper overlaps two inches on all
sides and is evenly distributed under the hold-
down ring.
Hold-down ring positioned correctly over filter
paper in filter pan.

3.2.2 Assembling the Filter (cont.)
4. Sprinkle 8 ounces of filter powder on the
filter sheet. Ensure the powder covers the
filter paper evenly.
5. Place the crumb screen in the filter pan.
Allow the crumb screen to rest on the top
edges of the hold-down ring.
6. Place filter pan cover onto the filter pan
assembly. Ensure the cover is correctly
positioned over the slip fitting.
NOTE: Previous production units had two
covers (front and back). If this is the case,
place both covers on the filter pan and ensure
that the front cover is correctly positioned
over the slip fitting.
Sprinkle the proper amount of filter powder evenly
over the paper.
Crumb screen properly placed.
Fully assembled pan with proper placement of lid
over slip fitting (slip-fitting orientation may vary
according to fryer system).

Assembling Filter Units with Latching Hold-down Rings
1. Place the filter screen in the pan. Ensure it is
properly seated in the bottom recess.
2. Place one sheet of filter paper over the filter
screen.
3. Install the hold-down ring over the filter
paper. Ensure the hold-down ring is properly
seated in the bottom recess.
Note: When placing the hold-down ring over
the filter paper, use care not to tear the filter
paper when locking the ring down. Sediment
can get into the filter system through tears in
the filter paper.

3.2.3 Installing the Filter
1. Slide the filter inside the fryer cabinet. For
latchless and latching hold-down ring
equipped filters, ensure the male-female slip-
fitting coupling is fully engaged. Ensure the
filter pan opening is directly under the center
dump tube (current) or angled drain tubes
(previous) to avoid splashing hot oil.
2. On filter-leaf equipped filters, ensure the
filter system hose disconnect is properly
attached to the filter-leaf disconnect. Ensure
the filter pan openings are properly
positioned under the drain tubes to avoid
splashing hot oil.
The filter pan slides under the
fryer (above), connecting with a
slip fitting (right). Slip fitting
location will vary (above or to
the side of the filter pan),
according to fryer system.
Filter-leaf disconnect properly attached to filter
system hose disconnect.
