WARNING! FIRE HAZARD
THE OIL LEVEL SHOULD NOT FALL BELOW THE MINIMUM INDICATED LEVEL AT ANY TIME.
THE USE OF OLD OIL CAN BE DAGEROUS AS IT WILL HAVE A REDUCED FLASH-POINT
AND BE MORE PRONE TO SURGE BOILING.
WARNING
INSTALLATION AND ALL CONNECTIONS MUST BE MADE ACCORDING TO NATIONAL AND
LOCAL REGULATIONS AND CODES IN FORCE.
WARNING
A COUNTRY APPROVED ALL POLE CIRCUIT BREAKER WITH A MINIMUM OPEN CONTACT
GAP OF 3mm MUST BE USED FOR PROPER INSTALLATION.
WARNING
THE FRYER IS NOT JET STREAM APPROVED. DO NOT CLEAN THE APPLIANCE WITH A
WATER JET.
NOTICE
INSTALLATION SHOULD ONLY BE DONE BY A COMPETENT SERVICE TECHNICIAN. THE
MODEL & SERIAL NUMBER, AND ELECTRICAL REQUIREMENTS STAMPED INTO THE DATA
PLATE, LOCATED ON THE INSIDE PANEL OF THE DOOR.
NOTICE
THIS APPLIANCE IS INTENDED FOR PROFESSIONAL USE ONLY, AND AS SUCH, SHOULD
BE OPERATED BY FULLY TRAINED PERSONNEL.
NOTICE
IT IS RECOMMENDED THAT THIS MACHINE BE INSPECTED BY A QUALIFIED TECHNICIAN
ON A YEARLY BASIS.
WARNING
THE POWER SUPPLY MUST BE DISCONNECTED SERVICING OR CLEANING THE UNIT.
WARNING
SHORTENING, WHEN IT IS AT OPERATING TEMPERATURES, IS VERY HOT AND
DANGEROUS! USE EXTREME CAUTION WHEN HANDLING! USE PROPER PROTECTIVE
GEAR SUCH AS INSULATED GLOVES, APRONS, FACE SHIELD, AND SLEEVES WHEN
HANDLING HOT SHORTENING. DO NOT ATTEMP TO MOVE MACHINE THAT HAS HOT OIL IN
IT. ALLOW TO COOLTO ROOM TEMPERATURE OR DRAIN THE OIL INTO A SUITABLE

Chapter 1: HOW DOES IT WORK?
The McDonalds Electric II fryer components function
in specific order of operation. Knowing and understand-
ing the sequence of fryer and components operation will
enable you to diagnose equipment failure more
accurately.
Heating System
Power to the machine is turned ON:
• If Fuse F1 on the Relay board is good, the A.C.
light will illuminate. The computer is supplied with
24VAC and, if the drain valve handle is closed, the
proximity switch will supply 24 VAC to the DVI
(drain valve interlock) Input at the computer.
• The computer is turned ON:
• The side on relay will be energized, closing the
circuit and the S.O. light on the Relay Board will
illuminate. If the hi limit is NOT tripped the safety
(side on) contactor will energize.
• Computer calls for heat:
• The 24 VDC "heat demand" relay will energize
supplying the heat demand contactor with 24 VAC
and the H.D. light on the Relay Board will
illuminate. This will also supply the computer with a
heat feedback signal.
Hi Limit System:
• If the hi limit trips, it causes the side on and heat
demand contactors to lose 24VAC supply and the
heat feed back loses 24VAC. The computer will
display IGNITION FAILURE or HEAT FAIL.
After the hi limit resets (unit cools to 375°F + 20°F)
the computer will have to be turned off and back
on for the unit to heat.
Hood Relay System: U.S./Canada units only
• There is one Hood Relay (K6) per "battery" of
fryers (located on rear bottom brace of left hand
fryer), it is wired in parallel to every computer (both
sides of a twin). When any side of any computer is
turned on this relay energizes (turning on the hood)
and will stay energized until all of the computers are
turned off.
Filter System:
• Opening the RED return valve handle will close the
proximity switch causing the "pump run" relay to
be energized. The pump motor will begin to run.
Closing the return valve handle will de-energize the
relay and the pump motor will stop running.
• The pump system is equipped with a circuit breaker
which will de-energize the system and the heat tape
in the event of overcurrent. The circuit breaker
switch must be in the ON position for the pump and
heat tape to operate.
• The return piping system may be provided with op-
tional heat tape to prevent solidification of solid
shortening. The heat tape is low wattage and is on
constantly to maintain liquid shortening in the line.
Chapter 2: COMPONENT
TROUBLESHOOTING:
Probe:
The resistance of the probe will change as the tempera-
ture changes. The resistance will decrease as the tem-
perature rises. The lower the temperature the greater
the resistance change will be per degree of temperature
change, as the temperature approaches the working
range of the probe, the resistance change will become
more linear.
If the probe is suspect, check its resistance and the oil/
air temperature at which it was taken. Compare these
5
L22-233 Rev 1 (04/03)
US
CAN
GB
values on the chart below.
If the probe returns an open circuit or 0 Ohms reading it
should be replaced. If the resistance varies more than
30 Ohms when being checked between 325-375°F the
probe will give a false temperature reading on the com-
puter and should be calibrated (up to 10°F) or replaced.
However, it will continue to operate at a slightly higher
or lower temperature.
Allow the oil to cool and check the probe resistance at a
lower temperature. As can be seen from the chart a
greater variation can be tolerated at a lower tempera-
ture.
Heat Demand Contactor:
The heat demand contactor has a 24VAC coil and will
energize when the correct voltage is supplied to the
coil. When energized, the contacts will close, allowing
current to flow through the elements. The coil
resistance is 192 ohms out of circuit.
Hi Limits:
The hi - limit switch is a normally closed switch until
the temperature at the hi-limit bulb reaches 425°F ±
20°F.
In order to test this switch it will be necessary to utilize
the temperature control hi-limit feature. Refer to PM
Card FR015 for instructions on how to perform this
test.
WARNING
During this test monitor the fryer closely. This test
will cause the oil to heat past the normal operating
temperature and can cause damage to the machine
and its operator if care is not taken.
If the switch does not trip between the prescribed
limits it is defective and should be replaced. Once
tripped, the switch cannot be reset until the oil has
cooled to approximately 375°F + 20°F. If the switch
does not reset after oil has cooled it is defective.
Once the oil has cooled the hi-limit reset button must
be pressed to reset the hi-limit relay on CE and export
units only.
Drain Valve & Return Valve Switches:
These switches are a magnetically operated proximity
switches. When the Drain Valve handle is moved to
the open position, the Actuator will move away from
the switch causing the switch to open. When the Drain
Valve is closed the switch will close.
Opening the RED return valve handle will close the
proximity switch causing the "pump on" relay to be
energized. The pump will begin to pump. Closing
the return valve handle will de-energize the relay and
the pump will stop pumping. These switches can also
be checked with an Ohm meter. The normal gap
between the Actuator and the Sensor switch on the
valve handle is
1
/
8
" -
1
/
4
" (3 - 6mm).
Transformer:
Transformers are multiple input voltage 24 volt output
voltage and can be checked by reading the input and
output voltages. A quick check for 24VAC can be done
at the relay board behind the computer. The AC led will
be lit if the F1 fuse is good and the board is receiving
24VAC
Elements:
Each Element has three coils inside it, check all element
coils out of circuit with an Ohm Meter, the resistance
should correspond to the chart below, if the resistance
varies more than 5 Ohm the element will need to be
changed. Also check for continuity to ground on each
end of the suspect element, there should be no continuity
to ground.
208 volt elements 18.5 Ohms
220 volt elements 20.7 Ohms
240 volt elements 24.6 Ohms
Safety (Side On) Contactor:
Check the coil with an Ohm Meter, the resistance should
be approximately 3 - 6 Ohms out of circuit. If it does
not have this resistance it should be changed.
