Safety instructions for certied
specialist personnel
• Check the work area
Before starting work on units
with combustible refrigerants,
ensure that any potential
ignition sources are removed
and the risk of igniting the
refrigerants is eliminated. The
aforementioned safety notes
for repairing the units must
be observed at all times. Work
may only be carried out by
authorised specialist personnel
with knowledge of handling
combustible refrigerants!
• Prepare the work area
Any persons present must
be informed about the repair
process accordingly and
persons not involved must
vacate the work area. Working
in rooms with limited space
is prohibited. Ensure that
sucient space is available at
the workplace. Ensure that the
ambient conditions are suitable
for working with combustible
refrigerants.
• Identify refrigerant leaks, check
the atmosphere
Refrigerant may unexpectedly
escape when working on the
refrigerant circuit. Ensure that
the atmosphere in the workplace
is not combustible at all times
by using suitable refrigerant
detectors. Be sure to ensure
that the refrigerant detector
used is suitable, approved
and calibrated for use with
refrigerant R290.
• Provide re extinguishers
Provide appropriate re
extinguishers before starting
work. For this purpose, dry
powder or CO2re extinguishers
are suitable.
• Remove any potential ignition
sources
Leaking refrigerant in
combination with corresponding
ignition sources can lead to an
explosion. All ignition sources
must therefore be kept away
from the work area at all times!
This also includes the smoking
of cigarettes. Inform all persons
present that this includes the
axing of safety notes and the
closing o of the work area.
• Sucient ventilation
Before starting work, ensure
that the work area is outdoors
or has sucient ventilation.
Acontinuous ventilation stream
is required while working.
The safety of the persons
working must be guaranteed
by the exhaust air equipment:
potentially leaking refrigerant
must be lead away safely and
drained into the atmosphere in
an optimum manner.
• Checking the refrigerant circuit
If electronic components need
to be replaced, ensure that
the spare parts have the same
function and identical technical
specications. The maintenance
and replacement regulations of
the manufacturer must always
be observed and complied with.
Please contact the support of the
manufacturer with any problems
or queries.
The following safety checks
must be carried out when using
combustible refrigerants:
- The ll level adjusts to the size
of the rooms in which the unit is
located.
- The exhaust air equipment and
its outlets function properly and
are not blocked or obstructed.
• Checking the electronic
components
A component and safety check
must be carried out before
repairing and maintaining
electronic components. If
safety cannot be ensured due
to a defect on a component,
installation must not take place
until safety can be guaranteed
again. If the defect on the spare
part cannot be remedied and
downtime of the unit is no
longer acceptable, an adequate
temporary solution must be
arranged. The owner/operator
of the unit must be informed
about this. The detailed safety
check must include the following
aspects:
- Capacitors are discharged.
Discharging must be done in a
safe process to prevent ying
sparks.
- There must be no electronic
components active or
uninsulated wires while lling,
repairing or cleaning.
- There must be no earthing of
the system.
7

• Repairs to closed components
Before repairing closed
components/housing parts, the
unit must be free from voltage.
If carrying out the repairs free
from voltage cannot be avoided,
the critical points of potential
refrigerant leakages must be
checked using a leak detector.
The following notes must be
observed when working on
electronic components if the
housing is changed in such a
way that its safety is inuenced.
This also relates to cases where
the lines are damaged, there
is excessive or incorrect pin
assignment, connections are
not assigned in the original
way or similar deviations to
the expected condition are
determined.
• Repairing of intrinsically safe
components
Do not introduce permanent
inductive or capacitive loads
into the existing circuits without
ensuring that the maximum
permitted voltages and
amperages of the assemblies
and lines are not exceeded.
Intrinsically safe components are
individual components that can
be operated in the presence of
ammable substances. The test
equipment must be adjusted
according to the situation-
dependent conditions. Only use
components which are ocially
approved by the manufacturer
as spare parts. Unapproved
components can cause a re
in the event of a leakage in the
refrigerant circuit.
• Wiring
Lines must be checked for the
following damage:
- Damage to the insulation -
Corrosion at the contact points
- Excessive pressure on the lines
- Damage due to vibrations
- Damage due to sharp edges
- Damage due to other
inuences not mentioned here
Also consider the ageing of
the material and continuous
vibration loads due to
compressors or fans when
checking.
• Identify combustible refrigerant
Do not use any potential
ignition source when searching
for refrigerant leaks under any
circumstance. The use of a leak
detection lamp or other similar
devices with a naked ame is not
permitted.
1. Ensure that the components
are installed correctly.
2. Ensure that sealing materials
are not changed in such a way
that combustible gases or
objects could penetrate into the
interior of the components.
3. Spare parts must correspond
to the manufacturer’s
specications.
• Leak detection methods
The following leak detection
methods are permitted for
systems with combustible
refrigerants. Electronic
equipment must be used
for detecting leaks. These
must be selected with the
sensitivity matched to the
situation and recalibrated if
necessary (calibration must
take place in a refrigerant-free
environment). The leak detection
device must be adjusted to
the lowest ammability limit
(LFL) of the refrigerant. Liquid
leakage instruments are
permitted for most refrigerants.
Chlorinated substances are
the exception here as the
chlorine in combination with
the refrigerants can cause
corrosion on the copper cables.
If a leak is detected, all potential
open ignition sources must be
removed immediately. If a leak
has been detected in the system
which requires reworking of the
piping in the form of soldering,
the system must be completely
free of refrigerant or, if possible,
the aected part disconnected
from the system using stopcocks.
The aected system parts must
be ushed with oxygen-free
nitrogen run before and during
the repair work.
• Emptying and evacuating the
system
If the refrigerant circuit must
be opened for repairs or other
reasons, this must be carried out
in a safe and professional way. In
any event, proceed with extreme
caution since ignition may occur
at any time!
NOTE!
The use of silicones can inuence
the eectiveness of leak
detection devices!
Intrinsically safe components
must not be insulated before
starting work!
CLIMIA

Local room air conditioner CMK 2950
Stick to the following procedure:
1. Drain the refrigerant
2. Flush the system with insert
gas
3. Evacuate
4. Repeat steps 2 to 3 if required
5. Opening the system by cutting
or soldering
The system must be ushed with
oxygen-free nitrogen in order to
guarantee safety. The ushing
process must be repeated
multiple times if necessary.
Do not use compressed air or
oxygen for the ushing process!
After evacuating, ushing
takes place by lling with dried
nitrogen until the operating
pressure is reached and then
the system must be evacuated
again. This ushing process must
often be repeated until there
is no more refrigerant in the
system. After the last ushing,
the system must be brought to
the ambient pressure in order
to start work. The ushing
process is indispensable when
soldering work is required on the
piping. Ensure that the vacuum
pump outlet is not near an
ignition source and continuous
ventilation is guaranteed.
• Filling process
The following requirements for
the general specications must
also be fullled during the lling
process:
- Ensure that no contamination
occurs from other refrigerants
(residues in the lling
equipment).
- Keep the lines as short as
possible to minimise the
likelihood of residues forming.
- Filling bottles and cylinders
must be stood upright.
- Ensure that the system is
earthed before lling.
- Label the system with the
refrigerant type designation
after lling
- Never exceed the maximum
ll level. The system must be
checked for leaks (pressure
test!) before lling. The system
must be checked for leaks once
more after lling and before
commissioning. Check for leaks
again when leaving the work
space.
• Labelling when shutting down
If a unit must be taken out of
operation and the refrigerant
must be disposed of, the unit
must be labelled with the date
and a signature. Ensure that the
note remains attached to the
combustible refrigerant.
• Transportation of units
which contain combustible
refrigerants
National provisions must be
observed.
• Storing of units which contain
combustible refrigerant
National provisions must be
observed.
• Transportation without the
original packaging
If the units are transported
without the original packaging,
they must be packed in such a
way that mechanical damage
is prevented. The units must be
transported upright.
9

Disposing of the units and their
components
Only recyclable materials are used
in the manufacture of the units and
components.
Help protect the environment
by ensuring that the units or
components (for example batteries)
are not disposed of in household
waste, but only in accordance
with local regulations and in an
environmentally safe manner, e.g.
using authorised disposal and
recycling specialists or council
collection points.
2.0 Guarantee
As a prerequisite for any
guarantee claims to be considered,
it is essential that the ordering party
or its
representative complete and return
the
"certificate of warranty" to Climia
Intakt GmbH
at the time when the units are
purchased and commissioned.
The guarantee conditions are listed
in the "General terms and conditions
of business and supply". Further-
more, only the parties to a contract
can conclude special agreements
beyond these conditions. In this
case, contact
your contractual partner
in the first instance.
Disposal of packaging
All products are packed for
transport in environmentally
friendly materials. Make a valuable
contribution to reducing waste
and sustaining raw materials. Only
dispose of packaging at approved
collection points.
4.0 Environmental
protection and

Control panel
Recessed
grip
The local air conditioning unit is
particularly well suited to exible
use.
The local room air conditioner com-
prises a oor-standing unit for the
indoor area
and an exhaust air hose to conduct
the heat away. The indoor unit
extracts the heat from the room to
be cooled by means of an evapora-
tor (heat exchanger) and transfers
it to the internal cooling cycle.
This releases the heat back to the
outside via another heat exchanger
(condenser) by means of the exible
exhaust air hose.
The condensate arising during
cooling mode is continually drained
o via the condenser by means of
a condensate pump located in the
unit - the condenser evaporates the
condensate and discharges it to the
outside via the exhaust air hose.
The unit lters and dehumidies
the air thereby creating a comfort-
able room climate. It works fully
automatically and oers numerous
additional options thanks to its mi-
croprocessor controller. The opera-
tion of the unit can be conveniently
operated by means of the infra-red
remote control included.

The condensate arising will
be collected in an internal
reservoir, fed to the condenser
and evaporated there. The
evaporated condensate will
then be fed to the outside via
the exhaust air hose. If the
condensate cannot be fed
away then a fault shut-down is
initiated along with an LED
signalling this.
OUR TIP
You will achieve a pleasant room
temperature if you set the desired
target temperature max. 4 to 7 °C
below the outside temperature.
Infrared remote control - General
notes
• With the unit switched on any
change to the settings will be
automatically transferred to
the room air conditioner.
The proper receipt of data will be
acknowledged with an audible
"beep".
• To operate the infrared remote
control it should be pointed
towards the receiver. The receipt
of data is only possible if there
are no objects between the
transmitter and the receiver.
• If the system is shut down for an
extended period it is advisable
to remove the batteries from the
remote control. OUR TIP
Help by reducing energy usage
in stand-by operation! If the unit,
the system or the components
are not being used, we
recommend disconnecting the
power supply.
Our recommendation does
not apply to safety relevant
components.
OUR TIP
Never use new and used batteries
at the same time, remove
discharged batteries immediately
and replace these with new
batteries of the prescribed quality
as there is a danger of discharged
batteries leaking.
Inserting the batteries into the
remote control
Before initial commissioning, insert
the supplied batteries (2 each, type
AAA) into the remote control.
1. Slide the battery compartment
cover on the rear of the remote
control to open it.
2. Insert the batteries with the
correct polarity. Observe
marking in the battery
compartment.
3. Close the battery compartment
again.
In order to put the unit back into
operation again after this fault shut-
down, proceed as follows:
1. Switch the unit o with the“I/0”
key and pull out the power plug.
2. Place a suitable container
underneath the condensate
drain of the internal reservoir.
The condensate drain is located
on the lower centre on the rear
of the unit.
3. Pull out the stopper from the
condensate drain and collect the
condensate that drains out.
4. Then insert the stopper once
again.
13

In cooling mode the unit creates
warm moist exhaust air, which must
be conducted away from the room
to be cooled. For this reason it is
necessary to plug the exhaust air
hose into the outlet opening on the
rear of the unit.
• Ensure that
the catches
for the
exhaust air
hose latch
securely
into the
two openings of the connection
aperture. Do not lay the exible
exhaust air hose with tight
bends and do not kink it in
order to be sure of eective
operation and to avoid this
causing damage to air ducting
components!
• The exhaust air of the unit
contains a certain amount of
moisture. For this reason it is
advisable to feed the exhaust
air to the outdoor area or to
outdoors.
Exhaust air routing variants
You can route the exhaust air out of
the building as follows:
Via a at nozzle
The at nozzle supplied can be used
in various dierent ways. It is pos-
sible to feed the at nozzle through
an open window and fasten it by
means of Velcro and a window suc-
tion cup (Fig. 4, page 15).
Likewise the at nozzle can be hung
in a tilted window (Fig. 6, page 15).
8.0 Before commissioning
The unit is positioned at the desired
location with the discharge side
pointing into the room. When
positioning, observe the following
notes.
• After unpacking the unit let it sit
on its transport rollers for at least
5 minutes before you switch it
on.
• Set the unit down in a stable
position on
a level and
rm oor. If
the oor is
uneven then
this can lead
to vibrations
and disturbing
noises.
• Check whether
the stopper in
the condensate
drain is present
and correctly
installed. There
is a risk of
uncontrolled
condensate
leakage after
commission-
ing.
• Never operate
the unit without
the air inlet
lter.
Otherwise, the
ns of the heat
exchanger can
become dirty
and the unit
loses performance.
• Ensure that persons and sensitive
objects, such as plants, are not
placed directly in the air ow
emerging from the unit.
Recirculated air
lter
• All extensions
to the power
supply must be
of a sucient
cable size and
must only
be used fully
rolled out.
Conduct the warm exhaust air away
CAUTION!
There must be a minimum
clearance of 30 cm between the
rear of the unit and the wall.
OUR TIP
In addition, with direct solar
radiation close the curtains and
blinds and keep the windows and
doors closed during operation.
CAUTION!
The exhaust air hose should
always be laid rising in the
direction of air ow and must not
be extended.

9.0 Commissioning
Before every commissioning the air
inlet and outlet openings should be
checked for foreign bodies and the
air inlet lter must be checked for
dirt. Blocked or soiled grills and lters
must be cleaned immediately, see
"Care and maintenance" chapter.
Cooling mode
1. Switch the unit on with the“I/O”
key.
2. Select cooling mode with the
"MODE" key.
3. Set the desired target
temperature with the "THERMO/
TIMER CONTROL" keys. The
selected target temperature will
be shown in the display. If the
fan speed selected is too large
or too small then this can be
adjusted with the "FAN" key.
Recirculation mode
1. Switch the unit on with the“I/O”
key.
2. Select recirculation mode with
the "MODE" key.
Via a wall pass-through
The hose supplied is rmly attached
to a wall pass-through. A suitable
wall pass-through is available as an
accessory (Fig. 6).
10.0 Shutdown
Temporary shutdown
If it is planned to shut down the unit
for longer periods e.g. during the
winter, proceed as follows:
1. Let the unit run in recirculating
operation for approx. 2 hours
in order to dry the surfaces
of the evaporator ns. This
will transport the remaining
moisture out of the unit and
this will avoid unpleasant
odours when the unit is re-
commissioned.
2. Switch the unit o with the "I/O"
key, pull out the power plug
and wind up the power supply.
Ensure that the cable is not
kinked or too severely bent. The
line can be fastened to the rear
of the unit.
3. Place a suitable container
underneath the condensate
drain of the internal reservoir.
The condensate drain is located
on the lower rear side of the unit.
4. Pull out the stopper from the
condensate drain and collect the
condensate that drains out.
5. Then insert the stopper once
again.
A missing stopper or an
incorrectly inserted stopper will
result in condensate leaking out
after re-commissioning.
NOTE
In some circumstances routing
the exhaust air via a rmly
attached exhaust air hose,
e.g. through closed doors or
windows, can lead to negative
pressure in the room in which the
unit is being used. If this should
reduce the performance of the
unit then arrange for the pressure
to be equalised.

11.0 Care and maintenance
Regular care and observation
of some basic points will ensure
trouble-free operation and a long
service life.
• Only clean the unit using a damp
cloth.
Do not use a jet of water.
• Do not use any caustic, abrasive
or solvent-based cleaning
products.
• Only use suitable cleaning
agents, even in the event of
severe soiling.
• Ensure that no moisture gets
into the unit. Clean the exhaust
air and outlet openings regularly
and thoroughly.
This is where dirt most often
collects rst.
• Clean the air lter on the indoor
unit at regular intervals, and
more frequently if necessary.
• We recommend that you take
out a maintenance contract with
an appropriate specialist rm.
This will guarantee that your
equipment always operates
reliably!
Permanent shutdown
Fig. 7 Changing the lter
Fig. 8 Cleaning with lukewarm water
Filter cleaning
The unit is equipped with an air
lter. This can be withdrawn from
the rear of the unit. The lter must
be cleaned at regular intervals.
Clean the air lter at intervals of no
more than 100 operating hours.
Reduce this interval in the case of
heavily contaminated air.
1. Switch the unit o and pull out
the power plug.
2. Pull the lter out of the unit (Fig.
7).
3. Clean the dust o the lter. Use
a vacuum cleaner in the event of
slight soiling.
4. In the event of heavy soiling,
clean the lter carefully in
lukewarm water (Fig. 8).
5. Allow the lter to dry in the air.
6. Insert the lter back into the
unit.
7. Ensure that the lter is dry and
undamaged.
CAUTION!
Never operate the indoor unit
without the original lter.
Without the lter, the heat
exchanger ns on the indoor unit
will be contaminated and the
unit will become less ecient.
CAUTION!
Care and maintenance work may
only be carried out if the unit
is disconnected from electrical
power.
6. Store the unit in an upright
position in a cool, dry and dust-
free location protected from
direct sunlight. Cover the unit
with a synthetic cover to protect
it against dust if desired.
NOTE
Check the level of dirt on the heat
exchanger ns as required.
