PANELS.
2. Disconnect the lamps flying leads.
3. Undo and remove the retaining collar.
4. Remove the 2 nuts retaining the light mount and spacer.

REMOVAL OF CLASSIC/ADVANCED CONTROLLER
Turn gas and electricity mains off
To Replace:
1. Remove cabinet side panels as described in REMOVAL OF CONTROL
CABINET PANELS.
2. Remove 4 nuts retaining controller.
3. Remove electrical leads from controller.
4. Loose control dial set screw and remove dial.
5. Remove controller.
6. Replace in reverse order.
To Calibrate:
(classic controls only, if required)
1. Fill the pan with unused oil to the indicated mark. Place a thermocouple 25
mm below the oil surface in the middle of the pan.
2. Light the unit and allow the oil to heat.
3. Temperature should settle at 374ºF(±9ºF), 190ºC (±5ºC). If adjustment is
required, disconnect main power. Adjustment is located on the back of the
control board. Turn adjustment counter-clockwise to increase temperature
and clockwise to decrease.
REMOVAL OF HIGH LIMIT THERMOSTAT
Turn gas and electricity mains off
This device is set to shut off the flow of gas to the burners to prevent oil
temperature from exceeding 230ºC. Manual intervention is required to reset the
control in the event of a lockout.
To Reset:
(CE only)
1. Remove 2 screws on ignition module cover. See figure 1 at beginning of this
section. Push the reset button on the body of the high limit thermostat.
To Check Operation:
Operation of the high limit thermostat must be checked regularly. Use the
following procedure:
1. Remove the upper control box from panel as described in REMOVAL OF
CONTROL CABINET PANELS.
2. Fill the pan with unused oil to the indicated mark. Place a thermocouple or
thermometer 25 mm below the oil surface in the middle of the pan.
3. Ensure that the electrical power is off before continuing. Disconnect the
leads from T6/COM and T7/NO on the controller. Connect the leads together
using the terminal block. This effectively removes the operating thermostat
from the circuit. It may also be bypassed with a jumper across the thermostat
terminals.
4. Switch the unit back on and light the unit as described in the lighting
instructions. The burners will light and heat up the pan.
DO NOT LEAVE THE
APPLIANCE DURING THIS TEST.
5. If the high limit thermostat is functioning correctly, the gas supply will cut off
as the temperature reaches 205 to 225ºC. Once the high limit thermostat has
tripped, switch off the mains electricity. Reconnect the operating thermostat
and replace all panels.
6. If the high limit thermostat switches, but not at the specified temperatures,
the thermostat requires replacement. Rejected thermostats must be logged
and returned.
7. To remove, see replacement procedures above. NOTE: After this test,
reconnect the regulating thermostat wires.
Calibration:
The high limit thermostat is of the fixed type. Its calibration point may not be
adjusted.
REMOVAL OF BURNERS
Turn gas and electricity mains off
1. Undo and remove the front two retaining nuts of the burner guard.
2. Undo the two retaining nuts at the side of the burner guard. Do not fully
remove. The burner guard will swivel back to allow access to the burners.
3. Undo and remove the retaining screws holding the burners.
4. Remove burner.
5. Replace in reverse order.
REMOVAL OF IGNITION ELECTRODE
Turn gas and electricity mains off
1. Disconnect electrical leads from ignition electrode. This electrode is also the
sensing electrode.
2. Remove ignition electrode from bracket.
3. Replace ignition electrode.
4. Replace electric leads.
