If the units are handled by human force, there must be at least three people to share the
load or pallet trucks must be used. If they are to be handled through pallets, they should be
preferably positioned horizontally side-by-side. The units should be properly fixed against

be taken. Figure-2 shows the recommended handling steps 0-1-2-3.
Figure-2. Handling Instruction
Note: Dropping the NEFFES 1200ST air purifier to the ground may cause a balance prob-
lem in the fans and make the unit unusable, even if the unit body is not damaged. This will
make the unit out of warranty.

CLEANING AND MAINTENANCE
Disconnect the unit from the mains power before the cleaning.
Regular maintenance will prevent unexpected breakdowns and performance losses in the
unit.
The filters become dirty over time, reducing air flow and causing performance loss. There-
fore, it is important to replace or clean the filters regularly.
General Cleaning
Always disconnect the unit from power supply before cleaning.
The external body of the unit may be cleaned with a slightly moist cloth as required. Abra-
sive cleaning agents should not be used.
Attention should be paid to prevent the moisture from reaching the interior surface of the
unit.

NEFFES 1200ST is a trademark. 11
Filters
The unit must not be run without filter. The filters must be completely attached to the unit
after a cleaning or replacement operation.
The filters must be replaced by the service.
Always disconnect the unit from power supply before a filter cleaning or replacement oper-
ation.
Always use protective gloves and mask when replacing the filters.
Do not dispose the filters with domestic wastes. The waste filters must be disposed safely.
Ask for help from our service teams for necessary technical support.
Fine Filters: When the fine filter replacement indicator is
on, the filter should be replaced.
Time to filters to get dirty may vary by the environment
where it is used and the frequency of use.
Disconnect the unit from power supply, open the front door
and the remove the filter by pulling it to yourself.
In time, dust or foreign matter accumulates on the filter,
and these materials may be harmful to human health.
Therefore, please use the personal protective equipment
specified in this manual during the filter replacement.
HEPA Filter: When the HEPA filter replacement indicator is
on, the filter should be replaced.
Time to filters to get dirty may vary by the environment
where it is used and the frequency of use.
Unplug the unit, open the front door, detach the HEPA filter
from the slide, hold it from the front side and remove it from
the filter housing by pulling it back as shown in the figure.
Insert the new filter in the housing. Then, close the front
door.
Since HEPA filters trap viruses and bacteria, the used ones
may contain harmful particles. After the filters are removed
using necessary protective equipment, they should be put
in a trash bag which should be tightly sealed. Then, this trash bag should be put in another
trash bag and tightly sealed. The date and time of this process should be written on the bag
with a non-erasable pen. After 72 hours, the bag containing the filter can be disposed with
domestic wastes. However, if the filters are not subjected to this process, they should be
regarded as medical waste and disposed accordingly. Make sure that the new HEPA filter
is properly fit in the filter housing. Otherwise, the unit will not operate properly. The junked
filters should be disposed properly and safely.

12 NEFFES 1200ST Air Purifier User Manual
Sound isolation: The sound isolation cassettes must be cleaned within the scope of
periodic maintenance. The silencer sets shown with numbers 8 and 9 in Figure-1 can be
removed by pulling back. The front silencer numbered 3 can be removed by loosening the
three M6 bolts under the cassette with a ten mm wrench. During cleaning, avoid contacting
the sound isolation sponge with any liquid (water, detergent solution, etc.), clean it with
gentle air flow. Do not use compressed air. Compressed air may deform the sound isolation
surface by breaking of parti-
cles from the surface.
Fan Maintenance and
Disassembly: In case of any
fault or need of maintenance
on the unit fan, you need to
remove the fan group from
its slides and demount the
fan silencer numbered 3
shown in Figure-1.
The procedures described in this section must be performed by competent personnel wear-
ing/using the Personal Protective Equipment specified in this manual.
lPull the tab that secures the fan group
on the casing with the slide mechanism.
lLoosen the three M6x25 bolts under the
tray carrying the fan by using a ten mm
wrench (See Cleaning and Maintenance
section, Sound isolation).
lPull the fan group out. lRemove the fan silencer.

Figure-5. Function Control Panel
2. On/Off
Connect the unit to a power supply and press “ON/OFF” button on the control panel (see
Figure-5, Number-1). The unit will start running with the fan in the 1st level and the green
LED shown with Number-2 in Figure-5 is on.
3. Speed Selection
The unit has 5 different speed settings.
Each time you press the “FAN SPEED” button on the keypad on the unit (see Figure-4,
Number 3), the fan speed will switch to the next level and the LEDs will be light on subse-
quently. For example, when the unit is at the 3rd level, 3 LEDs will be turn on in blue (See
Figure-5, Number -4).
When the fan is in the last stage, if the button is pressed once, the fan speed will switch to
the 1st stage.
When the unit works again after a power outage, it will resume the previous mode.
4. Alarms
The unit has 3 alarms.
“FINE FILTER” alarm; It is on when the fine filter gets dirty so as to affect the unit perfor-
mance. (See Figure-5 Number-7). When you replace the filter, the filter differential pres-
sure sensor will detect it and the warning light will be off.
“HEPA” alarm; It is on when the HEPA filter gets dirty so as to affect the unit performance.
When you change the HEPA filter, the filter differential pressure sensor will detect it and
the warning light will off. (See Figure-5 Number-8)

5. Child Lock
NEFFES 1200ST Air Purifier is equipped with a child lock for safety purposes. To activate
the lock,
lPress the lock button (see Figure-5, Number 5) and hold it for three seconds, all the
LEDs will flash and the unit switches to the child lock mode and the lock warning LED
(see Figure-5 Number 9) is on.
lFor each unit, initially, the 1st Password (1st Fan level LED is on) is active.
lIt can be changed if desired (see “Section-6 Setting a Password”).
lNo button functions in the child lock mode, only pressing the lock button is active. In the
child lock mode, the unit functioning status LEDs are still on (the fan level LED of the
active fan level is on, the warning LEDs can be seen, if any, but nothing can be changed).
lTo exit the child lock mode, press the lock button and hold it for three seconds, the LED
under the lock button (See Figure-5, Number 9) starts flashing. This indicates that you
can enter the password. If password is not entered within ten seconds, the unit returns
to the lock mode and the LED stops flashing. If the selected password is entered and
it is correct, all LEDs flash and the unit exits the child lock mode. If the password is
incorrect, this procedure will be repeated until the correct password is entered.
6. Setting a Password
lThe password setting mode can be switched when the unit is not in the child lock mode.
lPress and hold the lock button for eight seconds to switch the password setting mode.
If you press and hold it for three seconds, all LEDs flash and then turn of; if you continue
holding it, all LEDs showing the fan levels flash and then turn off at the eighth second
and the LED of the fan level where the password is set is on.
lThe first password (the first fan level LED is on) is active as a default. If the password
was changed before, the LED of the password that was activated at the password setting
mode is on)
lThe five LED lights showing the fan levels mean that there are five different passwords.
Press the fan level button to select the password you desire and then the relevant LED
is on. For example, all of the three LEDs should be on for the third password (see “Pass-
words” section for password explanations)
lAfter choosing the password, the password selected is saved if no change is made
within five seconds. The unit switches to the child lock mode and the lock warning (see
Figure-5 Number 9) is on.
