Amendment 7
Electrical Connection
NOTE: ALL ELECTRICAL CONNECTIONS MUST ONLY BE CARRIED OUT BY A QUALIFIED
PERSON.
Each fryer should be connected to an adequately protected power supply and isolation switch mounted adjacent
to, but not behind the fryer. This switch must be clearly marked and readily accessible in case of fire.
1. Check that the electricity supply is correct as shown on the Rating Plate attached to the inside of the
access door.
2. The supply terminal connections are located at the lower front of the fryer.
3. Open the door and remove the service panel (6 screws) located behind the drain valve(s) to allow
connection access for the electrical supply.
4. Bring the supply cable up through the grommet at the back of the fryer, and through the compression
type gland provided on the rear of the main electrical switchgear panel.
5. Connect the mains supply to L1, L2 and L3 switch connections for 3 phases.
6. Connect neutral and earth conductors to neutral stud and earth stud respectively.
7. For all connections ensure that conductors are secure and appropriately terminated.
8. Tighten the cable gland to secure against tension on the cable.
NOTE:
 This appliance must be grounded / earthed.
 Fixed wiring installations must incorporate an all-pole disconnection switch.
Commissioning
1. Before leaving the new installation;
a. Check the following functions in accordance with the operating instructions specified in the “Operation”
section of the User manual.
 Check the current draw and loading for the equipment. Refer specification section for correct
electrical requirements.
 Check that all the connections are correct and that all cover panels have been re-fitted.
 Check that the unit functions in accordance with the operating instructions.
 Ensure that the tank drain extension and this instruction manual are left with the appliance.
 Ensure that all the relevant details and contacts have been added to the front of the User manual.
b. The thermostat operation check should be carried out by filling the fryer with oil/shortening to the
appropriate oil 'FILL LEVEL' mark at the rear of the tank and setting the thermostat to 180°C. Light the
pilot burners and turn on the elements in accordance with “Operation Instructions” found in the User
manual.
c. The calibration of the thermostat should be checked once the oil is up to temperature. If a discrepancy
is found, the thermostat calibration should be referred to the supplier.
d. Ensure that the operator has been instructed in the areas of correct operation and shutdown procedure
for the appliance.
NOTE:
 If for some reason it is not possible to get the unit to operate correctly, turn off the
electrical power supply and contact a qualified service person. The supplier of this unit
will be able to recommend a suitable person.
 Make sure that the electrical supply is turned off before any service or maintenance work
is carried out.

5.5 Fault Diagnosis
Power switch on unit faulty
Check voltage to the input side of the power switch. If no
voltage then check wiring. If voltage then (with power switch
turned on) check power out of switch. If there is no voltage
out of switch then the switch is faulty - replace.
Element microswitch out of adjustment
Remove the overtemp panel from the unit, and manually push
the microswitch actuator arm. If this activates the fryer (the
power indicator illuminates) then the microswitch positioning
requires adjustment.
Element microswitch faulty
Check for voltage from microswitch terminals to neutral.
With the element down there should be power to the com
terminal and the n.o. terminal.
With the element up there should be power to the com terminal
and the n.c. terminal.
If not then microswitch is faulty - replace. If there is no power
to the com terminal at all then check wiring to the microswitch.
Overtemp thermostat faulty
Check voltage to the input terminal of the overtemp thermostat.
If no voltage then check wiring to overtemp.
If input voltage is correct then check voltage to output terminal
of overtemp. If there is no voltage (and the oil is below 150°C,
with the reset button not tripped) then the overtemp is faulty -
replace.
One element faulty
Remove wires from elements and check the resistances across
each element.
FN8127 element resistance: 10.2 ohms ±5%.
FN8224 element resistance: 20.4 ohms ±5%.
Alternatively a current check can be performed on each of the
phases. With the elements on and heating, each phase should
draw approximately 23.6A.
Thermostat out of calibration
Place an accurate digital thermometer in the oil. Set thermostat
to 170°C.
Allow the fryer thermostat to cycle once, and then record the oil
temperature for the next thermostat on/off cycle. The
thermostat should cycle within 10°C of the set temperature (i.e.
between 160 and 180°C), with an average cycle temperature of
approximately 170°C.
If oil temperature is outside these ranges then the thermostat
requires recalibration.

Check voltage into thermostat (terminal 2). If no voltage check
wiring.
Set thermostat to 180°C. Check for voltage out of thermostat
(terminal 1). If no voltage then the thermostat is faulty.
Heating contactor faulty
Check for voltage across terminals A1 and A2 of the heating
contactor. If there is no voltage then check wiring.
If voltage is correct then check for voltage at input side of
contactor (terminals 2, 4, and 6). If no voltage at any of these
terminals then check wiring.
Check voltage at output side of contactor (terminals 1, 3, & 5).
With the contactor energised, there should be voltage at all of
these terminals. If not then the contactor is faulty - replace.

Overtemp thermostat out of calibration
Place an accurate digital thermometer in the oil and set the
thermostat to its maximum position. Record the temperature at
which the overtemp trips.
If the oil reaches 225°C before the overtemp trips then the
main thermostat is either faulty or out of calibration, or the
heating contactor is faulty - refer below.
If the overtemp thermostat trips at a lower temperature, then it
is out of calibration and must be replaced.
Thermostat out of calibration
Place an accurate digital thermometer in the oil. Set the
thermostat to 180°C.
Allow the fryer thermostat to cycle once, and then record the oil
temperature for the next thermostat on/off cycle.
The thermostat should cycle within 10°C of the set temperature
(i.e. between 170 and 190°C), with an average cycle
temperature of approximately 180°C.
If oil temperature is outside these ranges then the thermostat
requires recalibration.
Thermostat faulty
With thermostat in the off position, the ‘cook’ indicator should
be off. If not then the thermostat is faulty - replace.
Heating contactor faulty
With power isolated from the unit, check for continuity through
the poles of the heating contactor. If there is continuity then
the contactor is faulty - replace.
