2. IMPORTANT INFORMATION
2.1 DESCRIPTION:The Dean CE Deep
Fat Decathlon Fryers are energy-efficient,
gas-fired units, design-certified by the
International Approval Services
(AGA/CGA), Gaz de France, NSF
International and manufactured to their
basic performance and application
specifications.
All units are shipped completely
assembled with accessories packed inside
the fryer vessel. All units are adjusted,
tested and inspected at the factory before
shipment. Sizes, weights and input rates
of all models are listed in this manual.
NOTE: The on-site supervisor is responsible
for ensuring that operators are made
aware of inherent dangers of
operating a deep fat fryer, particularly
aspects of oil filtration, draining, and
cleaning of the fryer.
2.2 PRINCIPLE OF OPERATION:
The incoming gas flows through orifices
and is mixed with air in the burners to
create the correct ratio for proper
combustion. The mixture is ignited at the
front end of each heat tube by the pilot
light. As the flame goes through the
burner tube, it is slowed by internal
diffusers. This slower and more turbulent
flame gives much better heat transfer to
the walls of the tubes, thereby heating the
oil better.
2.3 RATING PLATE: This is attached to
the inside right-hand corner of the front
door panel. Information provided includes
the model and serial number of the fryer,
BTU/hr input of the burners, outlet gas
pressure in inches WC and whether the
unit has natural or propane gas orifices.
DANGER!
THE FRYER MUST BE CONNECTED
ONLY TO THE TYPE OF GAS IDENTIFIED
ON THE ATTACHED RATING PLATE.
2.4 PRE-INSTALLATION:
a.GENERAL: Only a licensed plumber
should install any gas-fired equipment.
1. A manual gas shut-off valve must
be installed in the gas supply line
ahead of the fryer(s) for safety and
ease of future service.
2. The Dean CE Decathlon gas fryers
require 230 volts (AC) 50 cycle
electrical service and are equipped
with a 16-3 SJT grounded flexible
power cord for a direct connection
to the power supply. Amperage
draw for each unit depends on the
accessories supplied with the unit.
See detailed instructions packaged
with the fryer line-up.
CAUTION
Local building codes usually prohibit a fryer
with its open tank of hot oil from being installed
beside an open flame of any type, whether a
broiler or the open burner of a range.
b. CLEARANCES: The fryer area must
be kept free and clear of all
combustibles. This unit is designcertified for the following
installations:
1. Other than household use;
2. Non-combustible floor installation
equipped with factory-supplied 15
cm adjustable legs or 13 cm
casters;
3. Combustible construction with a
minimum clearance of 15 cm side
3
Page 5
and 15 cm rear, and equipped with
factory-supplied 15 cm adjustable
legs or 13 cm casters.
installing any hood. The duct system,
the exhaust hood and the filter bank
must be cleaned on a regular basis and
kept free of grease.
2.5 AIR SUPPLY & VENTILATION:
Keep the area around the fryer clear to
prevent obstruction of combustion and
ventilation air flow as well as for service and
maintenance.
a. Do not connect this fryer to an exhaust
duct.
b. Correct installation and adjustment
will ensure adequate air flow to the
fryer system. Proper input is 2m3 per
hour per kW for gas supplied.
c. A commercial, heavy-duty fryer must
vent its combustion wastes to the
outside of the building. It is essential
that a deep fat fryer be set under a
powered exhaust hood or that an
exhaust fan be provided in the wall
above the unit, as exhaust gas
temperatures are approximately 427538°C(800-1000°F). Check air
movement during installation. Strong
exhaust fans in the exhaust hood or in
the overall air conditioning system can
produce slight air drafts in the room.
2.6 ALTITUDE:
The fryer input rating (in m3/hr) is for
elevations up to 610 m. For elevations
above 610m, the rating should be reduced
four percent (4%) for each additional 305
m above sea level.
The correct orifices are installed at the
factory if operating altitude is known at
time of the customer’s order.
2.7RECEIVING AND UNPACKING:
Check that the container is upright.
Unpack the fryer carefully and remove all
accessories from the carton. Do not
discard or misplace these, as they will be
needed.
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 the dealer or
end-user.
d. Do not place the fryer’s flue outlet
directly into the plenum of the hood,
as it will affect the gas combustion of
the fryer.
e. Never use the interior of the fryer
cabinet for storage or store items on
shelving over or behind the fryer.
Exhaust temperatures can exceed
425ºC and may damage or melt items
stored in or near the fryer.
f. Adequate distance must be maintained
from the flue outlet of the fryer(s) to
the lower edge of the filter bank. A
minimum of 45 cm should be
maintained between the flue(s) and the
lower edge of the exhaust hood filter.
g. Filters and drip troughs should be part
of any industrial hood, but consult
local codes before constructing and
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 fifteen (15) days of
date of delivery. Be sure to retain
container for inspection.
NOTE: Dean Does Not Assume Responsibility
For Damage Or Loss Incurred In

3.4 LEVELING:
a. General: Place a carpenter’s spirit
level across the top of the fryer and
level the unit both front-to-back and
side-to-side. If it is not level, the unit
may not function efficiently, the oil
may not drain properly for filtering
and in a line-up it may not match
adjacent units.
b. Legs (Only):
1. If the floor is smooth and level,
level the unit by using the leg
screw threads. Adjust to the high
corner and measure with the spirit
level. The legs have about one
inch of adjustment threads.
2. Adjust leg height with an 18 mm
open-end or an adjustable wrench.
3. When leveling the fryer, hold the
leg body firmly to keep the leg
from rotating while turning the hex
bullet foot.

d. Re-leveling: If the fryer is moved, re-
level the fryer following the
instructions given in Step 3.4.
e. Restraints: This fryer must be
restrained to prevent tipping when
installed in order to prevent the
splashing of hot shortening. The
means of restraint depends on the type
of application, such as connecting to a
battery of appliances or installing the
fryer in an alcove, or by separate
means, such as restraining devices. A
bracket has been provided on the fryer
back panel for this purpose.
The install must be reviewed at the
time of installation to ensure it meets
the intent of these instructions. The
on-site supervisor and/or operator(s)
should be made aware there is a
restraint on the appliance and, if
disconnection of the restraint is
necessary, to reconnect this restraint
after the appliance has been returned
to its originally installed position.

disconnect device certified NF D
36124 (or other national standard).
(*) When exceeding 6 meters for a
configuration of more than 4 fryers, it
is necessary to provide a 33mm (1 ¼”)
rigid gas connection.
CAUTION
The fryer must be isolated from the gas supply
piping system by closing its individual, manual
shut-off valve during any pressure testing of the
gas supply piping system at pressures equal to
or less than 35 mbar (½ psig).
b. Rigid Connections: The fryer can be
connected singularly or as part of a
cooking line. Check any installersupplied intake pipe(s) visually and
clean threading chips, or any other
foreign matter before installing into a
service line. If the intake pipes are not
clear of all foreign matter, the orifices
will clog when gas pressure is
applied.
CAUTION
The fryer and its individual shut-off valve must
be disconnected from the gas supply piping
system during any pressure testing of the gas
supply system at test pressures in excess of 35
mbar (½ psig).
d. Manual shut-off valve: This gas
service supplier-installed valve must
be installed in the gas service line
ahead of the fryer in the gas stream
and in a position where it can be
reached quickly in the event of an
emergency.
e. Orifices: The fryer can be ordered to
operate on any available gas. The
correct safety control valve,
appropriate gas orifices, and pilot
burner are installed at the factory.
While the valve can be adjusted in the
field, only qualified service personnel
should make any adjustments with the
proper test equipment.
CAUTION
All connections must be sealed with a
joint compound suitable for the gas being

4. FRYER OPERATIONS
Refer to the rating plate and wiring
diagram located inside the front door. The
diagram can also be found in Chapter 8.
The fryer is equipped with a 230VAC
single-phase 50 hertz system. All
electrically operated appliances must be
electrically grounded to conform to CE
standards. Do not cut or remove the
ground prong from the power cord plug.
Respect the phase – neutral polarity. Do
not attempt to use the fryer during a
power outage.
WARNING!
IF GAS ODORS ARE DETECTED THE
GAS SUPPLY MUST BE SHUT OFF AT
THE MAIN SHUT-OFF VALVE AND THE
LOCAL GAS COMPANY OR
AUTHORIZED SERVICE AGENCY
CONTACTED FOR SERVICE.
4.1 INITIAL START-UP
a. Cleaning: New units are wiped clean
with solvents at the factory to remove
any visible signs of dirt, oil, grease,
etc. remaining from the manufacturing
process, then coated lightly with oil.
Before any food preparation, wash
thoroughly with hot, soapy water to
remove any film residue and dust or
debris then rinse out and wipe dry.
Also wash any accessories shipped
with the unit. Close the drain-valve
completely and remove the crumb
screen. Make sure the screws holding
the thermostat and high limit control
sensing bulbs into the vessel are tight.
b. Initial Pilot Light: All Dean Industries
fryers are tested, adjusted and
calibrated to sea level conditions
before leaving the factory.
Adjustments to assure proper
operation may be necessary on
installation to meet local conditions,
low gas pressure, differences in
altitude, variations in gas
characteristics, to correct possible
problems caused by rough handling or
vibration during shipment, and are to
be performed only by qualified service
personnel. These adjustments are the
responsibility of the customer and/or
the dealer and are not covered by the
Dean Industries warranty.
1. The inlet pipe at the lower rear of
the fryer brings incoming gas to
the pilot safety control valve, then
to the pilot and main burners. The
pilot is located high in the cabinet
center, at the base of the fryer
vessel. It will require a long match
or taper to light.
2. Ensure that the following steps are
done in sequence before lighting or
re-lighting the pilot:
12
Page 14
Pilot Light (Red)
(a) Turn off the manual shut-off valve on
the incoming service line.
Pilot Off (White)
(g) Turn the thermostat to any “ON”
setting and watch to make sure the
main burner ignites from the pilot.
CAUTION
When the fry vessel is filled with water, do not
drain the water from the vessel into the filter.
This will damage the filter pump and void the
warranty.
4.2 HEATING THE VESSEL
This step will check main burner
operation, initial thermostat/temperature
controller calibration, and clean the vessel
for initial food production.
a. Fill the fryer vessel with hot or cold
water to the oil level line scribed in the
back of the fry vessel.
(b) Turn the operating thermostat “OFF”.
(c) Depress the Pilot Off button (white) on
the safety control valve to turn “OFF”.
(d) Wait at least 5 minutes for any
accumulated gas to disperse.
3. Ensure the fryer tank is filled with liquid oil
(or water during testing) to the “oil level”
line scribed into the rear wall of the tank.
(a) Turn on the power switch.
(b) Open the manual shut-off valve on the
incoming service line.
(c) Apply a lighted match or taper to the
pilot burner head.
(d) Press the red Pilot Light button on the
safety valve gas and hold the button in
until the pilot stays lit when the button is
released. This may take a minute or
longer.
b. Set the operating thermostat dial /
temperature controller to 104ºC, just
above that of boiling water.
c. The main burner will ignite.
d. Reset the temperature controller to
93ºC.
e. The burners should shut-off just as the
water starts to boil.
f. When satisfied that the burners and
thermostat are operating properly,
drain the vessel of water and dry
thoroughly. Refill it with shortening
as directed below.
4.3 FINAL PREPARATION:
a. When using a liquid shortening
(cooking oil), fill the fryer to the “oil
level” line scribed into the back of the
fryer vessel.
(e) If the pilot does not stay lit, depress the
red Pilot Light button and re-light it,
holding the button in longer before
releasing. It may be necessary to relight the pilot several times until the
lines are purged of any trapped air and a
constant gas flow is attained.
(f) When the pilot stays lit, release the red
Pilot Light button.
WARNING
NEVER MELT A SOLID BLOCK OF
SHORTENING BY SETTING IT WHOLE
INTO THE FRY VESSEL. THIS IS
UNSAFE, INEFFICIENT AND VERY
DANGEROUS.
13
Page 15
b. When using a solid shortening, either
melt it first, or cut into small pieces
and tightly pack it, leaving no air
spaces and being careful not to disturb
the sensing bulbs.
c. If equipped with a Melt Cycle Control,
turn the melt cycle switch “ON” to
melt the shortening. The burners will
cycle on and off until shortening has
melted.
d. If the fryer does not have a Melt Cycle
Control, turn the burners “ON” for
about ten seconds, “OFF” for a
minute, etc., until the shortening is
melted. If you see any smoke coming
from the shortening while melting this
way, shorten the “ON” cycle and
lengthen the “OFF” cycle. Smoke
shows that you are scorching the
shortening and reducing its useful life.
e. Before starting operation, turn the
operating thermostat to the probable
working temperature; wait for the
temperature to stabilize then check
with a high-quality immersion
thermometer.
5. CLEANING
5.1 GENERAL:
Any piece of equipment works better and
lasts longer when maintained properly and
kept clean. Cooking equipment is no
exception. Your Decathlon Deep Fat Fryer
should be kept clean during the working
day, and thoroughly cleaned at the end of
each day.
5.2 DAILY:
a. Remove and wash all removable parts.
b. Clean all exterior surfaces of the
cabinet. Do not use cleaners, steel
wool, or any other abrasive material on
stainless steel.
c. Filter the cooking oil and replace if
necessary. The oil should be filtered
more often than daily under heavy use.
5.3 WEEKLY
a. Completely drain the oil from the fryer
into either the filter or a steel
container. Do not use a glass or plastic
container.
WARNINGS!
DO NOT GO NEAR THE AREA
DIRECTLY OVER THE FLUE
OUTLET WHILE THE FRYER IS
OPERATING.
ALWAYS WEAR OIL-PROOF,
INSULATED GLOVES WHEN
WORKING WITH THE FRYER
FILLED WITH HOT OIL.
ALWAYS DRAIN HOT OIL INTO A
METAL CONTAINER. HOT OIL CAN
MELT PLASTIC BUCKETS AND
CRACK GLASS CONTAINERS.
CAUTION
Do not drain water into filter. Water
will damage the filter pump.
b. Clean the vessel in the following
manner:
1. Close the drain valve and refill
with either a good commercial
cleaning solution and water, or
water and strong detergent.
2. Set the operating thermostat to
104ºC (220ºF). Bring to a rolling
boil, then turn the heat down to a
simmer and let the mixture stand
until the deposits and/or carbon
spots can be readily removed with
scrub pad or scrub brush.
14
Page 16
CAUTION
Never allow water to boil down to the point that
elements are exposed. This will damage them.
3. Scrub the vessel walls, bottom and
heating tubes.
4. Drain vessel and rinse with clean
water.
5. Refill with clear water, set operating
thermostat to 104ºC (220ºF), and
boil again. Once boiling is
completed, turn operating thermostat
off, drain, rinse, and dry thoroughly.
6. Immediately refill with cooking oil
or frying compound as directed in
Section 4.3.
5.4 PERIODIC
The fryer should be checked and adjusted
periodically by qualified service personnel
as part of a regular kitchen maintenance
program.
5.5 STAINLESS STEEL CARE
All stainless steel fryer cabinet parts should
be wiped regularly with hot, soapy water
during the day and with a liquid cleanser
designed for stainless steel at the end of
each day.
CAUTION
DO NOT let water splash into the tank of hot
oil. It will splatter and can cause severe burns.
a. Do not use steel wool, abrasive cloths,
cleansers or powders.
b. Do not use a metal knife, spatula or any
other metal tool to scrape stainless
steel! Scratches are almost impossible
to remove.
c. If it is necessary to scrape the stainless
steel to remove any encrusted materials,
soak the area first to soften the deposit,
then use a wood or nylon scraper only.

6.2 FILTER PREPARATION:
6.1 GENERAL:
a. These instructions are not intended to
replace the operating instructions that
came with your Dean Filter System.
They are intended to provide general
information about filtration
procedures and serve as a quick
reference guide.
b. For consistent product quality,
convenience and long-term savings,
use a high-quality liquid frying
compound.
c. The frying compound should be
filtered at least daily or even more
frequently if cooking is heavy. This
ensures the longest life possible for
the frying compound, gives better
taste to the food being prepared, and
minimizes flavors being transferred
from batch to batch.
d. When completing a filter cycle,
always close the return valve(s) at the
fryer(s) to avoid siphoning oil out of
the fryer into the filter and open the
valve at the filter to promote draining
of the return lines into the filter pan.
e. If using solid shortening, always
make sure the return lines are clear
before turning off the filter motor and
hang any flexible lines up to drain.
Solid shortening will solidify as it
cools and clog the lines.
CAUTION
a. Turn the fryer “OFF”.
b. Remove the filter pan assembly from
the cabinet.

f. Examine the filter paper, if it is dark
or scuffed in appearance, discard it.
Follow procedures listed in Section
7.4 to change dirty filter paper.
When filtering, never leave the filter
unattended. oil moving through the lines
could KNOCK a flexible return hose out
of the filter pan, spraying hot oil and
causing severe burns.
g. Remove the filter support grid and
clean.
h. Remove the filter pan and clean with
hot water, then re-install. Make sure
all residual water is removed and the
filter pan is dry. Any remaining
water will cause dangerous splattering
of hot oil when filtering.

k. Reconnect oil return quick disconnect
lines (if installed on the fryer).
6.3 FILTER OPERATION:
Dean Filter Systems are designed to be
used as either a portable unit or a built-in
filter as part of a fryer/filter system.
Portable means that it can be moved from
fryer to fryer.
The primary difference between filter
systems is how the filtered oil is returned
to the fryer vessel. Built-in systems have
an internally-plumbed oil return line
running from the filter’s quick disconnect
to a special port in the fryer vessel’s rear
wall where oil re-enters the fryer vessel.
Portable systems return the filtered oil by
means of a flexible oil return hose which
connects to the filter’s quick disconnect.
The operator uses a wand connected to
the end of the flexible oil return hose to
direct filtered oil into the fryer vessel
from above.
Filter operations always start with making
sure the unit is properly plugged in, then
rolling the filter to the fryer to be filtered.
The filter works directly under the fryer's
drain valve.

2. Turn the filter switch to the “ON”
position on the filter control panel
to begin pumping oil into fryer. If
your filter unit is equipped with a
flexible hose/nozzle, ensure
nozzle is positioned to return oil
safely into the fryer vessel.
3. When oil and fryer vessel are
clean, close the drain valve. It
takes the filter approximately 5 to
7 minutes to pump all oil back
into the fryer. Run the filter pump
an additional 10-15 seconds after
bubbles appear in oil to clear oil
return lines.
4. Make sure the drain valve is fully
closed.
1. Open the drain valve by pulling
the handle out. The oil will
transfer from the fryer vessel to
the filter pan.

fryer (either pull the red handle to
that fryer or open the valve at that
vessel) and continue to stir and
brush down the sides of the vessel
and heater tubes.
7. Open the hose connect valve (or
pull the yellow handle) at the fryer.
10. Re-install the drop-in grid into the
fryer.
11. Once the drop-in grid is covered with
shortening, turn the fryer power switch
“ON” and push the reset switch (if
applicable).
12. When the oil in the fryer starts to
bubble, open the filter cabinet door,
then lift the front of the filter pan and
allow the bubbling to continue for
approximately 10-15 seconds more. If
it is blowing bubbles, air is moving
through the lines and the lines cannot
be plugged.
13. Turn the filter switch “OFF”.
14. Close the oil return valve (or push in
the yellow handle) to the fryer and
close the fryer cabinet door.
NOTE: This completes the filtering of one
fryer. To filter additional fryers in the same
battery, repeat the process starting at step
3.b.1.

the oil return line by turning the red
handle at the filter. This drains the oil
return line back into the filter pan and
clears the lines.
16. Close the filter cabinet door.
NOTE: With the hose connect valve
“closed” at the fryer and the filter oil return
valve “open”, any oil left in the return lines
will drain into the filter pan and not be
trapped in the lines. These valves should be
kept in these positions when not filtering.

6.4 CHANGING FILTER PAPER:
FIGURE 6-7
The top piece of filter paper should be
discarded when it becomes dark or scuffed
in appearance. Follow these procedures:
a. Before changing the paper, use the
flexible hose (with about one inch of oil
remaining in the filter pan) to flush
debris from the filter pan sides onto the
paper.
b. Return all oil to the fryer.
c. Open the hold-down ring locking
latches and lift the ring out of the filter
tank. Your unit will be equipped with
one of the types shown in figure 6-7.
f. Replace the support grid, lay a new
filter sheet on the grid, then place the
old bottom sheet on top of the new
sheet. It is essential that two sheets of
Dean filter papers are used; use of
other than OEM parts will void the
filter warranty.
g. Replace the hold-down ring and latch
into position. Sprinkle 16oz of filter
powder evenly across the surface of
the filter paper. Re-install the crumb
catcher (if so equipped). Then
replace the filter pan cover.
h. The unit is now ready for operation.
6.5 TROUBLESHOOTING: These
troubleshooting procedures help locate
the most encountered problems and will
give possible solutions/corrective action
to be taken.
