device.
앬Never hold any burning objects close to the
device if they could be directly affected by the
emitted air.
앬Always pull out the power plug if the device is not
going to be used for any lengthy period of time.
Collections of dust can cause fire.
앬Never step onto the outdoor device and never
place anything on it.
앬Never use an unsteady or rusty base.
앬Never allow the device to run for too long with the
doors or windows open, or if the humidity is very
high. If the air conditioner runs for a long time in
cooling mode and the humidity is high (over
80%), condensed water may drip out of the
device.
앬Never stand on an unsteady base when you
remove the device from the holder on the wall.
앬Check that the condensation water can run off
unhindered. Water damage can result if the
condensation water cannot run off properly.
앬Never touch any metal parts on the indoor device
when removing the air filter. You may injure
yourself.
앬Never install the device in a room in which
combustible gases can be emitted. Emitted

that you install an earth-leakage circuit-breaker.
앬Leave the electrical installation of the 230 V
socket for the system to an authorized electrical
contractor. Incorrect installation can lead to injury
or damage to property.
앬If you are not confident in being able to assemble
the system, ask our customer service team or a
refrigeration contractor of your choice to do the
refrigeration part of the installation work. Incorrect
installation can lead to injury or damage to
property.
앬Incorrect installation may cause injury or damage
to the device.

앬Check the mains lead at regular intervals for
signs of defects or damage. A damaged mains
lead may only be replaced by an electrician or
ISC GmbH in compliance with the relevant
regulations.
앬The device must not be installed in laundries.
앬The device must be installed so that the plug is
accessible.
앬The temperature in the cooling circuit may
become very hot. You should therefore keep all
cables away from the copper pipes.
 CAUTION!
Read all safety regulations and instructions.
Any errors made in following the safety regulations
and instructions may result in an electric shock, fire
and/or serious injury.
Keep all safety regulations and instructions in a
safe place for future use.
Packaging:
The unit is supplied in packaging to prevent it from
being damaged in transit. The raw materials in this
packaging can be reused or recycled.
Tips on saving energy
Only use the air conditioner when you really need to.
Do not select too high a temperature for heating or
too low a temperature for cooling. Select the “Sleep”
function during the night.
Close all windows, doors and Venetian blinds in
order to reduce incoming sunlight as far as possible.
Principle of operation for cooling
Heat is extracted from the air in the room by the air
heat-exchanger (evaporator) in which the coolant
circulates. This air is conveyed to the outside air
heat-exchanger (condenser).
This gives off heat to the outdoor air. Electrical
energy is required for this. In certain circumstances
condensation may form on the evaporator on the
indoor unit, which will be removed by the
condensation hose.

2. The air conditioning system should not be
operated for a lengthy period of time with the air
flow directed downwards in cool or dehumidify
(DRY) mode. Otherwise condensation may be
deposited on the horizontal air flap and can then
drip on to the floor or on to furniture.
3. Do not adjust the horizontal air flap manually.
Always use the AIR DIRECTION or SWING
button for this purpose. If you adjust the air flap
by hand, it may suffer a malfunction in certain
circumstances. If a malfunction does occur, the
system must be stopped and restarted.
4. If the air conditioning system is restarted
immediately, it is possible that in certain
circumstances the horizontal air flap will not
move for approx. 10 seconds.
5. Do not operate the device with the horizontal air
flap closed.
6. If the air conditioning system is connected to the
power supply (the first time the power supply is
switched on), in certain circumstances the
horizontal air flap may generate a sound which
lasts for ten seconds. This is normal and is not a
malfunction.
10. Cleaning notes
Important!
Switch the device off and pull the mains plug each
time before cleaning.
Note!
The time intervals at which the device should be
cleaned are a factor of the area of installation. The
time intervals listed below should be maintained in
most cases.
Keep the outdoor device and the area around the
outdoor device clean. Regularly remove leaves, etc.
which can collect around the outdoor device.
Cleaning the housing of the indoor device
앬Clean the housing of the indoor device using
only a soft, wet cloth when necessary.
앬In order to avoid damaging the housing and
electronics, avoid the use of gasoline, thinners,
scouring powder, cleaners and the like when
cleaning.
Cleaning the air filters of the indoor device
Make sure that the air filters are clean! Soiled air
filters reduce the air output of the device. The air
filters of the indoor device should be checked and, if
necessary, cleaned on a monthly basis.
1. Raise the front panel of the indoor device until
the panel audibly clicks into position in its open
position (Fig. 10).
2. Raise the air filter slightly using the handle (Fig.
11 / Item A) to take the filter out of the filter
holder and then pull it downwards to remove it.
Take the air filter out of the indoor device (Fig.
12).
3. Additional filters are fitted to both air filters. The
yellow vitamin C filter is designed to convert
active oxygen into O2 and achieves a positive
effect for sustaining beautiful skin. The green bio
filter acts against unpleasant odors, bacteria,
viruses and allergens. Take the filters (Fig. 13)
out of the holder frames.
4. Clean the vitamin C / bio filters once per month
and change the filter every 24 months.
Replacement filters are available from ISC
GmbH.
5. Clean the vitamin C / bio filters carefully using a
vacuum cleaner.
6. Clean the netting in the air filter with a vacuum
cleaner or wash it out with warm water (max.
40°C).
7. Then dry the filter in a cool place.
8. Fit the vitamin C / bio filters back into the holder
frames. Place the two filters back on the air
filters.
9. Place the top part of the air filter back into the
device and ensure that its left and right edges
are correctly aligned. Then insert the filter in full
(Fig. 14).
10. Close the front panel again.
Cleaning the heat exchanger of the indoor device
The heat exchanger must be cleaned at least once
annually. To do this, remove the air filters from the
indoor device as described above.
앬Using a vacuum cleaner or a long-bristled brush,
carefully remove any dirt deposits on the heat
exchanger; this will avoid damaging the heat
exchanger fins. A damaged heat exchanger will
lead to higher operating costs.
앬Take steps to ensure that you do not injure
yourself on the fin edges!

11. General notes
Restarting after lengthy non-use
If the air-conditioning system has not been used for a
lengthy period, check the following before you switch
it on:
1. there are no objects covering the outdoor or
indoor unit.
2. the socket from which the unit is operated has
been installed correctly
3. the air filters are clean
Care precautions
If the air conditioner is not going to be used for some
period of time:
1. Let the fans run for 6 hours to allow the device to
completely dry out. Set the highest possible
temperature level while the fans are running.
2. Switch off the device and pull the power plug.
3. Clean the air filters and housing parts.
4. Remove all dirt from the outdoor unit.
5. Take the batteries out of the remote control.
If the following events occur during operation,
they do not constitute a fault.
1. Safety function of the air conditioning system,
compressor trip
a) After the system has been switched on again,
the compressor will not cut in until after a delay
of three minutes.
b) The device has a special function that prevents
cold air being blown out in heat mode if the heat
exchanger in the indoor device is in one of the
following situations and the set temperature has
not yet been reached:
– Heat mode has just been started.
– De-icing taking place.
– Heat mode with a low temperature setting.
c) The internal and external fans will be shut down
during de-icing. De-icing is taking place.
d) If the outdoor temperature is high and the
humidity is high, the outdoor device may ice up
whilst it is operating. This will result in reduced
heat output by the air conditioning system. If this
is the case the air conditioning system will
terminate heat mode and start de-icing mode
automatically. The de-icing time may be 4 – 10
minutes depending on the outdoor temperature
and the amount of ice deposited on the outdoor
device.
2. “White mist” is emitted from the indoor device
a) If the temperature difference between the air inlet
and air outlet is large and the relative humidity in
the room is also high. “white mist” may be
generated in cool mode.
b) If the air conditioning system is restarted in heat
mode after de-icing, “white mist” may be
generated by moisture in certain circumstances.
3. A low noise is emitted by the air conditioning
system
a) When the compressor is running or shortly after
it has been switched off, a hissing noise may be
heard, caused by the refrigerant flowing through
the pipes.
b) When the compressor is running or shortly after
it has been switched off, a “screeching” noise
may be audible, caused by the heat expansion
and cold contraction of the plastic parts in the
device due to temperature changes.
c) The first time the power supply is switched on,
the air flap will return to its initial position.
4. Dust is blown out of the indoor device
a) This is normal if the air conditioning system has
been switched off for a lengthy period of time
and when it is started for the first time.
5. A strange odor emanates from the indoor
device
a) This odor is generated in the indoor device and
is emitted by certain materials or pieces of
furniture or by cigarette smoke.
6. The air conditioning system switches to
exclusive fan mode from cool or heat mode
When the indoor temperature has reached the set
temperature, the compressor will cut out
automatically and the air conditioning system will be
operated in FAN mode. As soon as the indoor
temperature in COOL mode rises above the set
value or in HEAT mode it falls under the set value,
the compressor will cut in again.
7. In rooms with high relative humidity (over
80%), water droplet are deposited on the surface
of the indoor device in cool mode
Set the horizontal air flap to the vertical air outlet
position and select a HIGH fan speed.
8. Heat mode
In heat mode, the air conditioning system draws in
warm air from the outdoor device and dissipates it
through the indoor device to the indoor area. If the
outdoor temperature falls, the volume of hot air
drawn in through the air conditioning falls
accordingly. At the same time the heat load of the air
conditioning system increases as a result of the large
difference between the indoor and outdoor
temperature. This may result in the air conditioning

system being unable to achieve an adequate room
temperature. Please note that the heat function is
only really suitable for use during autumn and spring.
9. Automatic restart function: The device shuts
down complete in the event of a power failure
during operation
The OPERATION display flashes on the indoor
device after the power supply returns. Press the
ON/OFF button on the remote control to restart the
device.
10. A lightning strike or the mobile phone in a car
in use near the system may cause faults in the
device
In this case disconnect the deviceʼs power supply
briefly and then reconnect it. Press the ON/OFF
button on the remote control to restart the device.
