Information about the device
Device description
The device serves the purpose of cooling the room air. It further
filters and dehumidifies the air thus creating an agreeable room
climate.
The unit cools the room air by withdrawing warmth. The
absorbed warmth is emitted to the outside via the exhaust air
hose; cooled air is fed to the installation site by means of a fan.
Accumulating condensate drips from the evaporator onto the hot
condenser, there it evaporates and then is transported to the
outside via the exhaust air hose.
In ventilation mode the device provides the opportunity of air
circulation without cooling effect.
In dehumidification mode moisture is withdrawn from the air.
The device operates fully automatically and features a variety of
further options. The device can, for instance, be switched on or
off automatically with time delay via the timer function.
Operation of the device is possible either via the control panel at
the device or via the supplied infrared remote control.
The device was designed for universal and flexible application.
Due to its compact dimensions it can be easily transported and
used in all interior spaces.

Discharging exhaust air
30 cm
≥
≤
120 cm
• The exhaust air coming from the device contains waste
heat from the room to be cooled. For this reason it is
recommended to discharge the exhaust air to the outside.
• The end of the exhaust air hose can be fed through the
open window. If required, secure the open window with
the corresponding means, so that the end of the exhaust
air hose cannot shift.
• The end of the exhaust air hose can also be hooked into a
tilted window.
For this purpose, we recommend using a window seal
(optional).
• Install the exhaust air hose inclined with the air direction.
Example with exhaust air hose:
For installing the exhaust air hose please observe the following:
• Avoid kinks and bends in the exhaust air hose, as they
would lead to an accumulation of emitted humid air
causing the device to overheat and shut down.
• The dimensions of the exhaust air hose were especially
made to fit the device. Do not replace or extend the hose,
for it could cause a malfunction.
Connecting the power cable

Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
• Switch the device off.
• Hold onto the mains plug while pulling the power cable out
of the mains socket.
Warning of electrical voltage
Tasks which require the housing to be opened
must only be carried out by authorised specialist
companies or by Trotec.
Cleaning the housing
Clean the housing with a soft, damp and lint-free cloth. Ensure
that no moisture enters the housing. Protect electrical
components from moisture. Do not use any aggressive cleaning
agents such as cleaning sprays, solvents, alcohol-based or
abrasive cleaners to dampen the cloth.
Visual inspection of the inside of the device for dirt
1. Remove the air filter.
2. Use a torch to illuminate the openings of the device.
3. Check the inside of the device for dirt.
4. If you see a thick layer of dust, have the inside of the
device cleaned by a specialist company for cooling and airconditioning or by Trotec.
5. Put the air filter back in.
Cleaning the air filter
The air filters have to be cleaned as soon as they are dirty. This
is brought to light e.g. by a reduced capacity (see chapter Errors
and faults).
Warning
Ensure that the air filters are neither worn nor
damaged. The corners and edges of the air filters must
not be deformed or rounded. Before reinserting the air
filters, make sure that they are undamaged and dry!
1. Remove the air filters from the device.
2. Clean the filters using a slightly damp, soft, lint-free cloth.
If the filters are heavily contaminated, clean them with
warm water mixed with a neutral cleaning agent.
3. Allow the filters to dry completely. Do not put any wet
filters into the device!
4. Reinsert the air filters into the device.
Refrigerant circuit
• The entire refrigerant circuit is a maintenance-free,
hermetically sealed system and may only be maintained or
repaired by specialist companies for cooling and airconditioning or by Trotec.
EN 16
local air conditioner PAC 3900 X
Condensate discharge (manual draining)
In cooling and dehumidification mode condensate is formed,
which is mostly discharged via the exhaust air.
The remaining condensate is collected in a container within the
housing. The condensate ought to be drained regularly.
If too much condensate accumulates, the device switches off
and indicates this via the P1 error code on the segment
display(15).
1. Carefully transport or wheel the device to a suitable
location for discharging the condensate (e.g. a drain) or
position a suitable collection container under the
condensate outlet.
2. Remove sealing cap and rubber stopper from the
condensate outlet.
Activities required after maintenance
If you want to continue using the device:
• Leave the device to rest for 12to24hours, so the
refrigerant can accumulate within the compressor.
Wait 12to24hours before switching the device back on!
Acting contrary might lead to compressor damage and a
malfunctioning device. If so, any warranty claims will be
voided.
• Reconnect the device to the mains.
If you do not intend to use the device for a considerable time:
• Store the device according to the Storage chapter.
3. Drain the condensate.
4. Reinsert the rubber stopper in the condensate outlet and
reattach the sealing cap. Ensure the tight fit of the rubber
stopper, for otherwise there might be uncontrolled water
leakage.
ð The P1 error code on the segment display(15) will
disappear as soon as the condensate has been drained.
