MACHINE FUNCTION
Cold air is drawn into the dryer cabinet interior through louvres in the cabinet base, passes through
the large hole in the inner back panel adjacent to the fan and is driven through the element housing
on the inner back panel. After passing through the element windings and through holes in the drum
back plate into the drum interior, the now warm air is driven through the load to the front of the drum.
A webbing seal, fixed to the inside of the inner back panel, prevents warm air being driven into the
cabinet interior. As the drum revolves, the load is tumbled through the warm air stream, that extracts
moisture from the damp fabric. The now moist and cooled air passes through the filter in the air duct
on the back of the front panel, where any fluff picked up from the load is removed. The air then travels
through the front to rear air duct, leaving the dryer at the rear outlet.
If required, a vent hose may be attached to the outlet, to take exhaust air away from the dryer.
Acut-out on the element housing, cuts the electricity Live supplyto the element, if the airtemperature
in the housing becomes too high due to a restriction in the air flow, e.g a blocked filter. The cut-out
automatically resets when the air temperature drops to an acceptable level and cycles if the fault
persists.
A second 'one shot' cut-out, mounted alongside the 'auto reset' cut-out, is fitted as a safety device to
break the element Neutral connection, if the air temperature reaches an unsafe level due to failure of
the 'auto reset' cut-out.
There are two thermostats in the front air duct when only one is in use at any one time depending on
which programme is selected. These sense the exhaust temperature rise when the load becomes
dry and energise the timer motor on the main timer. This allows it to advance to cool run.

AUTOMATIC DRYING - Fitted to some models only
To work correctly High Heat has to be enabled and between 3 kg to 6 kg of Cottons dried. If smaller
or delicate loads are dried using the automatic setting, erratic results will be achieved.
Automatic Drying Explanation
NOTE: - The heat switch must be set to the high position otherwise there will be no circuit to the timer
motor or heater when the exhaust thermostat signals that the clothes are dry.
Sequence of Automatic Drying System
• First 20 minutes, full heat controlled by the timer. This is to pre-heat the clothes and drum before
the exhaust thermostats take control.
• The timer moves to its next cam position. The timer motor is now disconnected and the dryer
tumbles and heats.
• When the clothes are dry, the exhaust thermostat opens. This provides a Live supply to the timer
motor. The timer moves to the next cam position.
• 5 minutes of tumbling with the lower element only. The timer moves to the next cam position.
• Finally 7.5 minutes of tumble with no heat.

PROGRAMMES
COOLTUMBLE PHASE
This is the programmes final phase. Approximately 10 minutes before the finish, th eknob advances
automatically to the Cool Tumble Phase. Heating elements turn themselves off and clothing is cooled
down, after this the buzzer will sound (if selected) and the clothing ready to be taken out.
Always allow the dryer to complete this phase.
EASY IRON PROGRAMME
Easy Iron is a short 10 minute programme (8 minutes of heat, followed by a 2 minute cool tumble
period) which fluffs the fibres of clothing that have been left in the same position/location for an
extended period of time. The cycle relaxes the fibres and makes them easier to iron and fold.
NOTE: - Easy Iron is not a drying programme and should not be used for wet articles of clothing.
For best results: -
1. Do not load more than the maximum capacity. These numbers refer to dry weight.
Fabric Maximum Load
Cotton and Cotton mixtures 2.5 kg
Synthetics 2 kg
Denim 2 kg
2. Unload the dryer immediately after the end of the programme, hang, fold or iron the articles and
put them away in the closet. Should this not be possible, repeat the programme.
The Easy Iron effect varies from one fabric to the next. It works well on traditional fabrics like Cotton
or Cotton mix and less well on acrylic fabrics and on materials such as Tencel®.

COMPONENT DESCRIPTION
CONSOLE PANEL
This panel contains the user controls, which consist of a timer knob, for selecting the timed and
sensed drying periods, two push switches for heat selection and buzzer selection and a momentary
switch to start the dryer. A Red LED glows to indicate when the dryer is active.
TIMER
The timer system is made up from up to three timers, two mounted on the console and one on the
kickstrip.
Timer 1 controls the motor and heater. This has a spindle to which a knob is attached to enable the
user to select the required programme. Timer 2 controls the motor reversing; this is mounted on the
kickstrip. Timer 3 is used to delay the start of a programme. This also has a spindle to which a knob
is attached to enable a time delay to be set by the user.
The dryer must be set to the high heat position for the Eco drying system to operate failure to do so
will cause the timer to advance to cool run without drying the load.
Timer 1
Mounted on the console, the timer is used to control the motor and heating during the drying
programmes. The timer incorporates a timed cycle with 130 minutes of heated drying followed by a
7.5 minute cool run (137.5 minutes maximum cycle time marked as 140 minutes on the timer knob).
Two ’Eco' programmes are incorporated with are automatic programmes to provide heated drying
until a thermostat operates (when the load is dry), the timer then advances to a 7.5 minute cool run.
The cam of this timer is held on the heated part of the cycle by cutting the circuit to its motor.
The dryer motor continues to be reversed by timer 2. When the load is dry, a thermostat in the front
duct of the dryer operates which powers the motor of timer 1 and this allows the timer to advance to
cool run. The two 'Eco' programmes allow for different load sizes, for which different thermostats are
selected by the timer. Timer 2 reverses the motor direction every 2.5 minutes.
An optional crease removal programme is provided, which consists of 7.5 minutes of heat and motor
followed by a cool tumble period of 2.5 minutes. All of the above programmes have the option of an
external buzzer, which can sound until the timer is manually advanced.
Timer 2
Mounted on the base panel, the timer is used to control the reversal of the motor during the drying
programmes. The timer reverses the motor direction every 2.5 minutes.
Timer 3 - Not fitted to all models
This is an Electro-mechanical 12-hour timer used to delay the start of the drying cycle.
HEAT SWITCH
Normally open push-push switch. The switch locates into the facia moulding and it allows the user to
choose high or low heat settings. By consulting the wiring diagram, it can be seen that by operating
this switch, either all or half of the heater unit is selected, giving 2200W or 1100W.
For full heat switch is in the out position and low heat in the in (depressed) position.
High heat must be selected for the auto-drying programmes to operate, if low heat is selected the
dryer will advance to cool run without drying the load.
DOOR
A plastic moulded chassis with a glass bowl retained by plastic mouldings.

DOOR LOCK OPERATION
DOOR SWITCH - Models AS600VXFR, AS600VEX, TVM631EUHA
Normally open single pole micro-switch activated by the door on closure. It is the first switch in the
electrical circuit and therefore its rating corresponds to the full load of the product. The switch is
integrated in the door catch assembly that allows the door to be opened from the inside.
DOOR INTERLOCK RELAY - Models AS600VXFR, AS600VEX, TVM631EUHA
The door interlock relay mounts on the rear of the front panel. The relay has double pole isolation
which acts as an additional safety feature. The relay prevents the machine from operating when the
door is closed until the start switch has been activated. If the door is opened during a programme the
dryer will stop and will only start again when the door is closed and the start button pressed, this is a
safety requirement for tumble dryers with large door openings.
NOTE: - If the door is opened mid cycle, the machine will not restart when the door is closed.
The machine will only restart when the door is closed and then the Start button is pressed.
Bitron Door Lock Operation - Models AS600VKW, AS600AXAG
Door Open - Dryer Off
Trying to turn the machine on with the door open, the solenoid is unable to operate the bistable cam
to close the contacts, because it is locked by the latch.
Door Closed - Dryer Off
Closing the door, the latch (now rotated by the door hook) allows the movement of the bistable cam,
but the dryer is still OFF until the solenoid is energised.
Door Closed - Dryer On
Turning the machine on with the dryer door closed, the solenoid pushes the bistable cam (freed by
the latch) allowing the closing of the contacts.
Door Opened During Drying
When the door is opened during drying, the dryer will turn off automatically by the latch in its back
rotation, this pushes back the bistable cam towards the solenoid, opening the contacts.
Re-closing the door will not restart the machine until the machine is turned back on.
Safety Function
If the latch is accidental rotated by the customer with the door open, the machine will not start.
Without the latch in position, the latch rotates 30% further and sets the bistable cam in its safety
position. The safety position will not allow the machine to start. The door will need to be manually
repositioned to reset by a Service Engineer.
