Safety instructions
This machine is only intended for drying water-washed
garments.
Clothes that have been cleaned with chemicals/inflammable
liquids, must NOT be dried in the machine.
Remove clothes from the tumble dryer as soon as they are
dry. This prevents them from becoming creased, and reduces
the risk of spontaneous ignition.
The machine must not be used for drying foam rubber or
foam-like materials.
The machine must not be used for drying floor mops*.
The machine must not be used by minors.
The machine must not be hosed down with water.
Mechanical, electrical and gas installations must only be
carried out by authorised personnel.
If the machine has a fault, this must be reported as soon as
possible to the person in charge. This is important for your
own safety and for the safety of others.
Gas dryers only:
The machine is not to be installed in rooms
containing cleaning machines with perchloroethylene,
TRICHLOROETHYLENE or CHLOROFLUOROCONTAINING
HYDROCARBONS as cleaning agents.
What to do if you smell gas:
Do not try to light any appliance.
Do not touch any electrical switch; do not use any phone in
your building.
Evacuate the room, building or area.
Contact the laundry manager.
*Applies only to floor mops containing polypropylene.
Servicing the dryer
Refer servicing to qualified personnel.
Improper servicing can result in hazardous conditions, fire,
explosion, property damage, and personal injury.
Some components may have sharp edges!
Wear gloves when handling mechanical components.

A door switch ensures that the dryer stops automatically if the dryer is opened during the
program sequence, see section "door switch".
Operating panel
Depending on configuration. Can be equipped with one or serveral of the following:
• Buttons for setting programs, temperatures, and drying time.
• Start/stop button.
• Display showing program selection, remaining drying time and error code, if any.
• Heating indicator, lamp lights when heating is on.
Coin drop / card reader
The dryer is available with a factory-installed coin drop, a factory-installed card-start
system, or it can be prepared for field installation of a card start system.
On vending models, insertion of a coin or card buys an owner-programmed drying time.
Motor
The dryer has two motors, motor 1 operates the blower and motor 2 operates the drum.

Periodic maintenance
Functional inspection
1
Functional inspection comprises:
1. Checking the door switch.
2. Test run.
1. Check the door switch
Check whether the safety lock works. The drum
must stop when the door is opened. When the
door is closed again, the tumbler must not start
until the start button is pressed, fig. 1.
2. Test run
Let the tumble dryer work on a program with heat
for 5 minutes; then check by opening the door
and feeling with your hand whether the heating
works.
Maintenance
The following should be carried out at regular
intervals, depending on the frequency of use.
Daily
• Check that the drum stops when the door is
opened.
• Check that the lint screen under the door has been
cleaned. Use a soft brush or your hand, fig. 2.
• Check that the lint screen is not damaged.
• Check that the tumble dryer will not start until the
start/stop button has been activated.

Periodic maintenance
Monthly
1
• Wipe off/clean drum and lifters with citric acid
(Acidum citricum). If soap/softener residue
remains, it is recommended also to use a coarse
sponge.
Lack of cleaning the lifters can reduce the
automatic residual moisture control in the
clothes resluting in the clothes being moister
than requested when the program has ended,
fig. 1.
Quarterly/Semi-annually
• Check that the fresh-air intake at the rear of the
tumble is not clogged by lint or blocked in any
other way.
• Check that the filter is not broken.
• Clean drum and lifters with a mild detergent
(using a sponge) at least once every quarter.
• If the filter is defective it needs replacing.
• At least once a year a skilled expert should
check the inside wearing parts of the tumble
dryer and clean them of lint.
Maintenance
The area surrounding the dryer
Fresh-air intake to the room
Check that the fresh-air intake to the room and
the exhaust ducts/pipes from the room are not
clogged by lint/dust or blocked in any other way.
Dryer area
Check that the dryer area is clear and free
from combustible materials, gasoline and other
flammable vapours and liquids.

Optimizing the air flow
Service
manual
Air flow
Outlet dimensioning
It is important that the dryer has the correct air volume compared to each dryer’s effect.
If the air flow is below the minimum, the dryer will be forced to switch the heating off thus
prolonging the time it will take to dry the load.
An air flow above the needed is unnecessary and can result in a cold laundry room and
noise from the piping and outlet and in extreme cases prolonged drying time.

Circuit boards MUST be protected
from static electricity!
Remember!
• Always use an earthed wrist strap.
• Without the antistatic wrapping, the board is unprotected.
• Keep all items that can cause static discharge (such as plastic bags,
fabric, and the like) away from the circuit board.
• Items like plastic, foam plastic, nylon, or cellophane wrapping are all big
generators of static electricity.
• Static electricity can not be felt, heard or seen till the voltage reaches
2500V.
• Board components can be damaged by static electricity under 100V.

Inlet air - Thermistor element (PT100 sensor)
Function
The thermistor element measures the temperature of the heated air entering the drum.
The resistance of this device is normally 110 Ohms at 20°C (68°F) and increases as the
temperature rises.
The signal is returned to the PCB and this ensures that the inlet air does not become
excessively hot, thus preventing scorching of garments.

The main circuit board turns the heating unit off when the outlet air thermistor indicates
that the required temperature has been reached.
The resistance of this device is normally 4 to 6 kOhms at 20°C (68F) and it drops as its
temperature increases.

Electric heated dryers
1
The electric heating element A is located in
the bottom of the chimney, fig. 1.
The air is drawn through the louvres on the
back plate and on to the heating element.
The heated air passes through the garments
and the drum vents.
A
Then the air flows from the perforation through
the filter and via the outlet into the air.
The heating element is switched on by the
heating contactor K4, which is controlled by
the Selecta Control.
Overheating thermostat
Electric heated dryers are equipped with two
overheating thermostats connected in series
(one 180°C and one 90°C) which switches
off in case of overheating and error code E08
flashes in the display, fig. 2.
The switching on (reset) must be done
manually but first the cause of the error must
be detected and the switched off overheating
thermostat must be found.
This error is often caused by reduction of the
air circulation in the dryer due to insufficient
air in the room or due to the dryer being
overloaded.
If the dryer is stopped before the cool down
sequence has ended the after-heat can cause
the overheating thermostats to switch off.
The following error code is related to this
section.

Gas error (E 14)
Should a gas error occur error code E 14 will
flash on the display, fig. 2.
In general gas errors occur due to supply
shortage either if there is a gas failure or the
gas pressure is too low.
Other errors which can cause E 14 :
• Ignition failure, check the distance between
the electrodes, fig. 3.
The distance must be 3 mm (± 0.5 mm).
• The sensor (the ionization must detect the
flame).
2
• The control box could be defective.
Replace the defective control box,
fig. 3 & 4.
Gas heating problems often occur due to
shortage in the air supply. It is therefore very
important that the air supply to the room is
sufficient.
A rule of thumb for dimensioning the room’s air
inlet is that the air inlet opening must be 5 times
the size of the air outlet opening.
To read more about the evacuation system see
the installation manual for T4190.

RMC general
RMC is a measuring method used to stop the
dryer when the garments are dry.
The current dryness/moisture of the garments
is continuously measured and the drying
sequence is brought to an end when the preset level has been obtained.
The measuring signal is collected from the
steel bands by means of the collector graphies
which conduct the measuring signal to the
Process Module.
One of the collector graphies is connected to
a lifter and the other one to the drum casing.
A weak measuring current is sent through the
garments which are in touch with the lifter,
and as the resistance increases gradually
as the garments are getting more and more
dry the measuring signal is ready for onward
processing by the Control PCB.
Replacing collector graphies
1. Demount top plate.
2. Replace collector graphies fig. 2.
