Safety Precautions
Safety Precautions
Do not dry unwashed items in the machine
The machine is not to be used if industrial chemicals have been used for cleaning.
Do not allow minors to use the machine.
Do not hose down the machine with water.
The machine's door lock must under no circumstances be bypassed.
Items that have been soiled with substances such as cooking oil, acetone, alcohol,
petrol, kerosene, spot removers, turpentine, waxes and wax removers should be
washed in hot water with an extra amount of detergent before being dried in the
machine.
Items such as foam rubber (latex foam), shower caps, waterproof textiles, rubber
backed articles and clothes or pillows tted with foam rubber pads should not be
dried in the machine.
Fabric softeners or similar products should be used as specied by the fabric
softener instructions.
The machine may not be used to dry oor mops that contain polypropylene.
The nal part of a drying cycle occurs without heat (cool down cycle) to ensure that
the items are left at a temperature that ensures that the items will not be damaged.
WARNING. Never stop the machine before the end of the drying cycle unless all items
are quickly removed and spread out so that the heat is dissipiated.
Remove garments from the machine as soon as they are dried. This prevents them
from becoming creased and reduces the risk of spontaneous ignition.
If the machine develops a fault, this must be reported to the person in charge as soon
as possible. This is important both for your safety and that of others.
The machine must not be located where a door, sliding door, etc., can block the
machine's door
The machine is not intended to be used by people (including minors) with reduced
physical or mental capacity or lack of experience and knowledge. Such people must
be instructed in the use of the machine by a person who has responsibility for their
safety. Minors must be supervised to ensure that they do not play with the machine.
Adequate ventilation has to be provided to avoid the back ow of gases into the room
for appliances burning other fuels, including open res.
Gas heated tumble dryer:
The machine is not to be installed in rooms containing cleaning machines with
perchloroethylene, TRICHLOROETHYLENE or CHLOROFLUOROCONTAINING
HYDROCARBONS as cleaning agents.
If you can smell gas,
• Do not switch on any equipment
• Do not use electrical switches
• Do not use telephones in the building
• Evacuate the room, building or area
• Contact the person responsible for the machine
In order to prevent damage to the electronics (and other parts) that may occur as the
result of condensation, the machine should be placed in room temperature for 24 hours
before being used for the rst time.

Description of principal components
Description
Dryer type T4190 is available as electric and gas heated.The dryer has a vent into
the open air.
Programs - Compass Control
The dryer has a microprocessor. The microprocessor control has different functions
including:
• Drum reversing for less tangling of large items.
• Service program for adjustment parameters eg. temperatur, cool-down time.
• Dryer functions monitoring - errors occurred during the program sequence are
registered in the log. Some of the error codes are shown on the display at the same
time.
• RMC (Residual Moisture Control), the dryer stops automatically when the clothes have
reached the required residual moisture level.

10 Description of principal components
Loading door
Normally the dryer has a right-hinged door.
The door is, however, reversible (see section "cabinet, door reversal").
A door switch ensures that the dryer stops automatically if the dryer is opened during the
program sequence, see section "door switch".
Knob operation
Turn and select by using the knob and the following appears:
• Program selection
• Start button
• Language selection
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
40 mm
1
2
Functional inspection
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.
2. Test run
Check that the fan, drum rotation and heat all
stop when the door is opened max. 40 mm.
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.

20
Monthly
Dryer with RMC
In order for the residual humidity control to work
in an optimal manner it is important that the lift
rolls inside the drum and the glide surfaces for
the graphite carbon are cleaned.
If these surfaces are not cleaned the automatic
residual humidity control can be degraded resul-
ting in the garment being damper than required
at the conclusion of the programme.
See g. 1.
Cleaning
Wipe off/clean drum and lifters with citric acid
(Acidum citricum). If soap/softener residue re-
mains, it is recommended also to use a coarse
sponge.
Cleaning intervals depend on the operational
usage. Cleaning must howeverbe carried out at
least once each month.
It is recommended that the glide surfaces are
cleaned every third to sixth month or as re-
quired. See g. 2.
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.
• 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.
