1. Servicing Requirements
1.1 Health & Safety
Note: When servicing the Titan Aerotech oven, health and safety issues must be
considered at all times. Specific safety issues are listed below with their appropriate
icon. These are illustrated throughout the service information to remind service people of
the health and safety issues.
1.1.1 Electrical Safety
WARNING! TO AVOID ELECTRIC SHOCK!
Do not attempt to service this oven without suitable training and
qualifications.
Ensure the mains power has been disconnected before servicing any part of the oven. If
the power is required to be on for electrical fault finding, then extreme care should be
taken not to make contact with electrical components other than with testing probes.
Ensure the oven is turned off when removing any electrical component or connection.
1.1.2 Electrostatic Discharge
An anti-static strap is to be used as electrical static discharge (ESD)
protection when servicing electronic components.
1.1.3 Good Working Practices
Ensure the work areas are kept tidy and free of hazards while servicing the
oven. On completion of the servicing, ensure the oven and work areas are
left clean and tidy.
1.1.4 Insulation Test
Megger test to check insulation.
Warning Short together the phase and neutral terminals to avoid damaging
any electronic circuitry.
1.1.5 Sheet Metal Edges
When working around cut sheet metal edges use appropriate gloves or
protection to eliminate the chance of receiving a laceration.

1.2 Specialised Tools
1.2.1 Static Strap
The static strap is to be used as E.S.D. protection when replacing or handling electronic
components.
1.2.2 Fisher & Paykel Smart Tool

2.32 Self-Clean Pyrolytic Cycle
Duration: 3hrs
Pyro Temp: 925°F (500°C)
Heat-up time: 50 minutes approx.
Holding time: 100 minutes approx.
Cool-down time: 30 minutes
If a Self-Clean Cycle will not start, check that there are no meat probes inserted and that
the control knobs of the cavity not being cleaned (in a double oven) are in the ‘OFF’
position.
The oven self-clean mode operates by heating the oven to a temperature of
approximately 885°F (473°C). This burns off and breaks down soil and grease deposits.
The ash residue that remains can simply be removed from the cool oven with a damp
cloth or sponge. The self-clean cycle normally takes about three hours.
To start a Self-Clean Cycle
1. Turn the oven mode dial until ‘Self Clean’ appears in the display.
2. Select the maximum temperature using the temperature dial.
‘000’ will appear in the temperature display. This will change to when the
cycle begins.
‘Door Lock’ and ‘Clean’ will show in the clock display.
The door lock will automatically activate once the Self-Clean mode and maximum
temperature have been selected.
A countdown of minutes remaining will be shown in the clock display.
The Broil / Grill inner element, the throat element, the smoke eliminator element and the
vent fan operate during the Self-Clean Cycle. Additionally, during the first fifteen seconds
of each minute the bake element is on and during the third fifteen seconds of each
minute the Broil / Grill outer element is on.
The cooling fan for the cavity being cleaned will be on high speed. The cooling fan for
the other cavity will be on low speed.
During the Self-Clean Cycle in a double oven, the cavity not being cleaned cannot be
operated in any mode.
The oven heats to its cleaning temperature of 885°F (473°C) and maintains this
temperature until approximately 2½ hours into the cycle.
The elements then turn off and the cool down period commences. When the
temperature reduces to 356°F (180°C) the door will unlock and the ‘Door Lock’ display
will disappear from the clock display.
When the self-clean cycle has finished, ‘Clean’ and ‘00:00’ will flash in the clock display
until it is returned to manual operation. Press the PUSH TO CLEAR button and turn the
oven mode and temperature dials to the OFF position to do this.
At the completion of the self-clean cycle, there may be grey ash deposited on the inside
of the oven. The amount of ash is dependent on the amount of soil in the oven before
cleaning. To remove the ash, wait until the oven has completely cooled. The bulk of the
ash is easily removed with a small brush or dry cloth, then wiped over with a damp cloth.
The self-clean mode can be cancelled at any time by turning the oven dials to ‘OFF’.
‘Clean End’ will appear in the oven mode display but if the oven temperature has already
reached 482°F (250°C) the door lock will remain activated until the oven cools to 356°F
(180°C).

3. Use & Care of the oven
3.1 Setting the Clock
The clock has a default 12 hour display and a minute timer function. ‘AM 12:00’ will show
and the colon will flash when the oven has been turned on at the wall. While the colon is
flashing, rotate the PUSH TO CLEAR knob until the correct time of day is displayed.
Press CLOCK or wait 8 seconds until the colon stops flashing to adopt the time that has
been set.
3.2 Oven Mode Dial and Display
This is turned to select the desired oven mode. When the mode is set the lights and
cooling fan will come on.
3.3 Temperature Dial and Display
This is turned to select the desired temperature.
3.4 Oven Modes
The oven has 9 cooking modes plus Warm and Self Clean. These use different
combinations of elements and the oven fan as follows:
• True Aero. A concealed heating element surrounding the fan in
the rear of the oven heats air, which is then blown into the oven
cavity.
• Aero Bake. The oven fan circulates hot air from the upper outer
and the bake elements.
• Bake. Heat comes from the upper outer and the bake elements.
• Aero Pastry. Heat comes from the bake element and is
circulated throughout the oven cavity by the oven fan.
• Pastry Bake. Uses the heat from the bake element only.
