Information about the device
Device description
The devices PT4500S, PT6500S, PT15000S and PT23000S
are chiefly used for cooling room air. Moreover, the devices also
provide the opportunity of air circulation without cooling effect.
The devices are operated via the control panel(1) at the
respective device.
The devices are air conditioners with split cooling circuits. The
refrigerant circuit of the basic device(2) is self-contained. For
the dissipation of warmth it is emitted via one or two heat
exchangers to a second cooling circuit. A second circuit
transports warmed water/ glycol mixture to the external heat
exchanger(6) to cool it down again.
The air conditioners PT4500S and PT6500S can be used with
one heat exchanger. The PT15000S requires two heat
exchangers. The PT23000S operates with three heat
exchangers.
The devices cool the room air by withdrawing warmth. The
refrigerant cools down the air coming from the room and in
doing so absorbs the heat. The thusly cooled air is introduced to
the room, where the device is positioned, via the fan.
Accumulating condensate is discharged via a separate
hose(3,11) to the external heat exchanger in order to be
drained or to evaporate there.
The "operating hours counter" option is already integrated in
the control. As standard the PT15000S and PT23000S come
with an installed energy meter. For PT4500S and PT6500S
you can optionally order a dual counter.

Setting the operating mode
The following operating modes are available:
•cooling: The room air is circulated by the device and
cooled at the same time.
•ventilation: The room air is circulated by the device.
The device will start up in cooling mode approx.3.5min after
switch-on.
• You can select ventilation mode (without cooling) by means
of the VENT. button(32).
– The VENT. indication(22) will be illuminated when
ventilation mode is activated.
Automatic defrost
At low ambient temperatures, ice may form at the evaporator
during dehumidification.
The device then carries out an automatic defrost by means of
the hot gas feed. Here, a hot cooling agent is led into the iced
evaporator for its surfaces to defrost.
The duration of the defrost process can vary. The hot gas
automatic defrost system integrated in the device automatically
switches on the defrost cycle at regular intervals.
Do not switch the device off during automatic defrost. Do not
remove the mains plug from the mains socket.
After automatic defrosting the device keeps running for approx.
90s for the purpose of air circulation – regardless of the
ambient temperature and the desired room temperature.
Afterwards the device resumes operation with the set values.
Shutdown
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
• Switch off the device.
• Hold onto the mains plug while pulling the power cable out
of the mains socket.
• If necessary, remove the condensation drain hose and any
residual fluid from it.
• Clean the device according to the Maintenance chapter.
• Store the device according to the Transport and storage

Errors and faults
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
Wear safety glasses
For start-up, maintenance and troubleshooting always
wear suitable safety glasses.
Wear protective gloves
For start-up, maintenance and troubleshooting always
wear suitable protective gloves.
Wear foot protection
For transportation, start-up, maintenance and
troubleshooting always wear suitable foot protection.
The device does not start:
• Check the power connection.
• Check the on-site fusing.
• Observe the operating temperature according to the
chapter Technical annex.
• Check whether the POWER(23) indication is illuminated. If
not, check the power connection and the plug. The fuses
inside the plug and/ or on the mainboard might be
defective.
In case of defective fuses also check the points listed
under the error message HIPS.
• Wait for 10minutes before restarting the device. If the
device is not starting, have the electrics checked by a
specialist company or by Trotec.
The device works with reduced or no cooling capacity:
• Check whether cooling mode is selected.
• Check the air filter(s) for dirt. If necessary, clean or replace
the air filter(s).
• Check the minimum distance to walls or other objects.
Position the device a little more in the room's centre if
required.
• Check whether any windows and/or doors of the room are
open. If so, close them.
• Check the temperature setting at the device. Reduce the
set temperature if it is higher than the room temperature.
• Also check the points listed under the error message HIPS.
The device is loud or vibrates:
• Check whether the device is set up in a stable and upright
position.
Condensate is leaking from the basic device:
• Check the device for leaks.
The compressor does not start:
• Check whether the overheating protection of the
compressor has tripped. Disconnect the device from the
mains and let it cool down for approx. 10minutes before
reconnecting it.
• The compressor may start up with a delay of 3minutes, as
it is provided with an internal protection against direct
restart.
The device gets very warm, is loud or is losing
performance:
• Check the air inlets and air filters for dirt. Remove external
dirt.
• From the outside, check the device for dirt (see chapter
Maintenance). If the inside of the device is dirty, have it
cleaned by a specialist company for cooling and air-
conditioning or by Trotec.
• Air may have accumulated in the water-glycol circuit of the
external unit that is higher positioned. Actuate the air vent
valve(37) on the external unit to completely bleed the
circuit.
Note
Wait for at least 3minutes after maintenance and
repair work. Only then switch the device back on.
The device still does not operate correctly after these
checks:
Please contact the customer service. If necessary, bring the
device to a specialist company for cooling and air-conditioning
or to Trotec for repair.

Error codes Error messages
When the Alarm LED lights up, the following error messages
might be displayed:
Message Cause Troubleshooting
PunP • The internal pump alarm is activated. • Empty the pump container (e.g. by means of a suction pump), then
check whether the pump operates properly again. The alarm stops as
soon as the water has been completely drained from the pump
container.
LOPS • The air filter might be contaminated. • Check the air filter for dirt. If required, clean the air filter (see chapter
Maintenance).
• When the fault has been eliminated, disconnect the mains plug and plug
it back in after 5s to reset the alarm.
• There might be a leak in the internal
refrigerant circuit.
• Have the device checked by a specialist company for cooling and air-
conditioning.
• When the fault has been eliminated, disconnect the mains plug and plug
it back in after 5s to reset the alarm.
HIPS • Plug connections at the external
cooling circuit do not fit properly.
• The pump of the external cooling
circuit is not operating properly.
• The fan of the external heat
exchanger does not operate.
• The device might not be operating
due to excessive ambient
temperatures.
• There is insufficient water in the
cooling circuit between the basic
device and the external unit.
• Check the plug connections at the external heat exchanger.
• Check the internal brass filter of the pump for dirt and clean it if
necessary (see “Water filter” in exploded assembly drawings).
• Check the pump. If necessary, have the pump checked by a specialist
company for cooling and air-conditioning.
• Check the fan. If necessary, have the fan checked by a specialist
company for cooling and air-conditioning.
• Check the outside temperature (temperatures above 35°C can be
critical).
• After the inspection press the RESET button(40).
• Disconnect the mains plug and plug it back in after 5s to reset the
alarm.

• Check whether there is sufficient water in the tank(5).
Note:
After eliminating the HIPS fault, vent the external heat exchanger at the vent
valve for the water circuit(37).
