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.
In ventilation mode the device also 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In dehumidification mode moisture is withdrawn from the air.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.
Handling the device can be accomplished via the control panel
at the device or 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.
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 trickles from the evaporator onto the
hot condenser, there it evaporates and then is transported to the
outside via the exhaust air hose.

Activities required before starting maintenance
Danger!
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.
Danger!
Maintenance 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 device 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 air-
conditioning or by Trotec.
5. Put the air filter back in.
Cleaning the air filter
The EVA air filter and the CON air filter must be cleaned as soon
as they are dirty. This is brought to light e.g. by a reduced
capacity (see chapter Errors and faults).
Caution!
Ensure that the air filter is not worn or damaged. The
corners and edges of the air filter must not be
deformed or rounded. Before reinserting the air filter,
make sure that it is undamaged and dry!
1. Remove the EVA air filter and the CON air filter from the
device.
2. Clean the EVA air filter and the CON air filter with a slightly
damp, soft, lint-free cloth. If the filter is heavily
contaminated, clean it with warm water mixed with a
neutral cleaning agent.
3. Allow the EVA air filter and the CON air filter to dry
completely. Do NOT insert a wet filter into the device!
4. Reinsert the EVA air filter and the CON air filter into the
device.

Operating manual – local air conditioner PAC 3500 E
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 should be drained manually on a
regular basis.
If too much condensate accumulates, the device switches off
and indicates this via the FL indication on the segment
display(29).
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(12).
2. Unscrew the sealing cap from the condensate outlet(12).
3. Remove the rubber plug.
12
4. Slightly tilt or incline the device towards the drain or
collection container.
5. Let the condensate run off completely.
6. Reattach the rubber stopper to the condensate outlet(12).
Check the rubber plug for tight fit.
7. Screw the sealing cap onto the condensate outlet(12).
12
ðThe FL indication on the segment display(29) will go out as
soon as the condensate has been drained.
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 air-
conditioning or by Trotec.
Activities required after maintenance
If you want to continue using the device:
• Leave the device to rest for 12-24hours, so the
refrigerant can accumulate within the compressor. Wait
12-24hours 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.
