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. A
safe discharge process must
be employed 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.

CTK 190 mobile air dehumidier
• 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 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
units 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!

10
CLIMIA
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 system).
- 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
• 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!
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.

11
CTK 190 mobile air dehumidier

CLIMIA
It is evident that the corrosion rate
below 50% relative humidity (RH) is
low, and below 40% is negligible.
The corrosion rate increases
signicantly above 60% RH. This
threshold for damage as the
result of humidity also applies to
other materials, such as powdery
substances, packaging, wood and
electronic units.
Buildings may be dried in a variety
of ways:
1. By heating and air exchange:
The air in the room is heated in
order for moisture to be removed
and then this air is fed outside.
All of the energy that is involved
is lost together with the moist air
that is released.
2. By air dehumidication:
The moist air that is present
within an enclosed space is
continuously dehumidied
according to the condensation
principle.
With regard to energy consumption,
air dehumidication has one
distinct advantage:
Energy expenditure is limited
exclusively to the air volumes
present. The mechanical heat that
is released by the dehumidication
process is fed back into the room.
Under normal use, the
air dehumidier uses
approximately 25% of the
energy that is required for
the
"heating and ventilating"
principle.
Relative air humidity
Our ambient air is a gaseous
mixture which always contains a
certain volume of water in the form
of water vapour. This volume of
water is specied in g per kg of dry
air (absolute moisture content).
1m3of air weighs approx. 1.2 kg at
20°C
Depending on the temperature,
each kg of air is only capable of
absorbing a certain volume of
water vapour. Once this capacity
has been reached, the air is referred
to as“saturated” and has a relative
humidity (RH) of 100%.
Relative humidity is understood to
mean the ratio between the current
quantity of water vapour in the air
and the maximum possible quantity
of water vapour at the same
temperature.
The ability of the air to absorb water
vapour increases as the temperature
rises. I.e. the maximum possible
(absolute) water content becomes
greater as the temperature rises.
The correlations occurring when
air is dehumidied are based on
physical laws.
These are depicted here in graphical
form in order to provide you with a
brief overview of the principles of
air dehumidication.
Using
Climia air dehumidiers
• Even if windows and doors
are well insulated, water and
moisture are still capable of
penetrating thick concrete walls.
• The water required for setting
in the production of concrete,
mortar and plaster etc. may only
be diused after 1-2 months.
• Even moisture trapped in the
masonry after high-water or a
ood is released very slowly.
• The same is also true of moisture
contained in stored materials for
example.
The moisture (water vapour)
released from parts of a building
or materials is absorbed by the
surrounding air. As a result, the
moisture content increases, which
ultimately gives rise to corrosion,
mould, rot, peeling of paint and
other unwanted damage.
By way of example, the diagram
shows the corrosion rate of metal in
dierent levels of humidity.

Building materials and structures
are capable of absorbing
considerable volumes of water, such
as brick 90-190 l/m³, heavy concrete
140-190 l/m³ and limestone 180-270
l/m³.
The drying of moist materials such
as masonry is eected as follows:
• The moisture moves
from the inside of
the material to its
surface
• Evaporation occurs on the
surface = Transfer of water
vapour to the ambient air
• The air containing water vapour
is constantly circulated through
the air dehumidier. The air
is dehumidied and, slightly
heated, leaves the unit in order
to re-absorb water vapour
• In this way, the moisture
contained in the material is
reduced gradually.
The material is dried!
The accumulated condensate is
collected in the unit and drained o
from there.

As it ows through or over the evaporator, the air stream is cooled to dew
point. The water vapour condenses, and is collected in a condensate trap
from where it is drained o.

Water vapour condensation
Because the capacity for the
maximum possible volume of
water vapour increases as the air is
heated, the volume of water vapour
contained remains constant and so
relative humidity falls.
In contrast, because the capacity for
the maximum possible volume of
water vapour decreases as the air is
cooled, the volume of water vapour
contained remains constant and so
relative humidity increases.
If the temperature continues to
fall, the capacity for the maximum
possible volume of water vapour
is reduced so much so that it is
ultimately equal to the volume of
water vapour contained in the air.
This temperature is referred to as
the dew point. If the air is cooled
to below dew point, the volume of
water vapour in the air will become
greater than the maximum possible
volume of water vapour.
At this point, the water vapour
begins to precipitate.
This condenses to water and
moisture is removed from the air.
Examples of condensation include
steamed-up window panes in
winter, or the moisture on the
outside of a cold drinks bottle.
As the relative humidity of the air
increases, so too does the dew
point, making it easier for the
temperature to fall below it.

Condensation heat
The energy transferred to the air
from the condenser consists of:
1. The amount of heat derived
beforehand in the evaporator.
2. The electrical drive energy.
3. The condensation heat released
by liquefying the water vapour.
Energy must be supplied when
liquid is converted into a gas.
This energy is designated as
evaporation heat. It does not cause
any increase in temperature, but is
required to convert a liquid into a
gas. Conversely, energy is released
when gas is liquefied, this is
designated as condensation heat.
The amount of energy from
evaporation heat and condensation
heat is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
From this it is evident that the
condensation of water vapour
causes a large quantity of energy
to be released.
If the moisture that is to be
condensed is not introduced by
evaporation in the room itself,
but from outside, e.g. through
ventilation, the condensation heat
released contributes to the heating
of the room.
With drying operations, a heat
cycle is created, whereby heat
is consumed for evaporation
and released for condensation.
When dehumidifying fed air,
a larger contribution of heat is
created, which manifests itself as a
temperature increase.
Generally speaking, the time
required for the drying process is
not only dependent on the output
of the unit, but is determined to
a greater extent by the speed at
which the material or building
section loses its moisture.

7.0 Unit description
Operating sequence
The units are switched on and off
by the power key.
The fan extracts the moist room air
through the intake grill with filter,
evaporator and the condenser
behind.
Heat is removed from the room air
on the cold evaporator. The air is
then cooled to below dew point.
The water vapour contained in
the room air is then deposited
as condensate or rime on the
evaporator fins.
On the condenser (heat
exchanger), the cold and
dehumidified air is warmed up
again and discharged back into
the room via the outlet grill
with a temperature increase of
around 5 - 10 °C above the room
temperature.
The processed, dry air then re-
mixes with the room air.
Continuous circulation of the room
air through the unit gradually
reduces the relative humidity
(% RH) in the room to the desired
humidity level.
Depending on the room air
temperature and the relative
humidity, condensed water will
drip into the condensate trap
and then through the integrated
discharge nozzle into the
condensate container below either
continuously or only during the
defrosting phases.
A float is installed inside the
condensate container. In the event
that the container is full, the float
will activate a microswitch which
will switch off dehumidification
mode.
The units switch off and the
“container full” indicator light
on the control panel illuminates.
This extinguishes again when
the empty condensate container
is re-inserted.
The units then restart after
aswitch-on delay of around 3
minutes.
In unattended continuous
operation with an external
condensate connection, the
condensate that occurs is
drained continuously via a hose
connection.
The units have been designed for
universal and straightforward air
dehumidification.
Their compact dimensions allow
the unit to be transported and set
up with ease.
The units operate in accordance
with the condensation principle
and are equipped with a
hermetically sealed refrigerant
system, heat gas defrosting, low-
noise and low-maintenance fan
and connection cable with plug.
The fully automatic control, the
variable hygrostat, the condensate
container with integrated overflow
protection and the connection
nozzle for condensate drainage
guarantee fault-free continuous
operation.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU regulations.
The units are dependable and offer
ease of operation.
The units are used in all locations,
where dry air is a must and where
economic consequential damage
(such as that caused by mould)
must be prevented.
The units may be used for the
drying and dehumidification of
areas such as:
• Living rooms, bedrooms,
shower rooms or cellar rooms
• Weekend homes and
caravans
• Warehouses, archives,
laboratories
• Bathrooms, wash rooms and
changing rooms etc.
• Basements, storage rooms

11.0 Commissioning
Before commissioning the unit or if
local requirements dictate, the air-
inlet grill and air-outlet grill must
be checked for contamination.
Important notes prior to
commissioning
• All extensions to the electrical
connection must be of a
sufficient cable size and must
only be used fully rolled out or
unrolled
• Never use the power supply
connection cable as a pull cord
• After being switched on,
the units operate fully-
automatically until switched off
by the hygrostat or float when
the condensate container is full
• The condensate container must
be inserted properly
The unit cannot be operated if
the condensate container is not
inserted properly!
• In order to prevent damage to
the condenser, the units are
equipped with a mechanism
that prevents the compressor
being immediately switched
back on after it is switched off
The units do not switch back
on until a waiting time of
around
3 minutes has elapsed!
• If the units work in continuous
operation with an external
condensate drainage
connection, refer to the
relevant section

Adjusting the discharge
direction
The dehumidified room air is
discharged on the top of the unit.
The pivotable air flap [S] is used to
adjust the discharge direction.
Press the air flap’s rear surface [D]
to open it.
The front folds upwards. The air
direction can be adjusted infinitely.
The following notes must also be
observed in full:
• If possible, open the air flap
completely to direct the air flow
upwards
• Ensure that the air can
discharge without hindrances
This is the only way to
guarantee optimum unit
operation!
• Ensure that sensitive objects
such as house plants are not
placed directly in the air flow
emerging from the unit
DS
Automatic defrost system
The moisture contained in the
room air condenses when cooling
and coats the evaporator fins
with rime or ice depending on the
air temperature and the relative
humidity (% RH).
The automatic defrost system that
is integrated in the unit switches
the defrost cycle on if required.
The rime or ice that has
accumulated on the exchanger
surfaces is defrosted using heat gas
as required.
This defrosting method is
particularly fast and effective, and
guarantees high dehumidification
performance.
Dehumidification mode is only
paused for a short time during the
defrost phase.
The “Defrost mode” indicator light
indicates that the defrost cycle is
running.
Adjusting units/moisture
The unit’s dehumidification power
is entirely dependent on the
conditions inside the room, the
room temperature, the relative
humidity and observance of the
notes in the “Set-up” chapter.
The higher the room temperature
and relative air humidity, the
higher the dehumidification power.
A relative humidity of around
45 to 60 % is sufficient in living
rooms. The air humidity should not
exceed 40 to 45 % in warehouses,
archives, etc.
The set target value can be read
off from the status lights "AUTO"
and "MAX".
In automatic mode ("AUTO"), the
unit operates fully automatically
and switches off automatically
after reaching the set target value.
In continuous operation
("MAX.") the unit works without
interruption and ensures maximum
dehumidification.
The setpoint is changed by
pressing the SET key. The LED
display changes from right to left.
MAX. AUTO
rF
SET
NOTE
The maximum possible
dehumidification power is
only obtained when the air
flap is opened completely.
NOTE
If the room temperature is
sufficiently high, the surface
of the fins will not be cold
enough for frost formation to
occur, rendering defrosting
unnecessary.
Therefore, the air dehumidifier
works economically.
NOTE
The built-in hygrostat is
not a calibrated measuring
instrument and is located
inside the unit.
The averaged air humidity
in the installation room may
deviate from the set value
under certain circumstances.

Continuous operation with
external condensate outlet
The units are equipped with a
special connection nozzle on the
left side.
A standard 1/2” water hose can
be connected to this.
1. To do this, use a suitable tool to
release the cover [F] from the
unit wall.
Only required for the first
connection!
2. Connect a sufficiently long
and suitable drain hose to the
connection nozzle that is now
exposed.
In unattended permanent
operating mode, the condensate
should preferably be drained into a
lower-level drain.
If using an external collection
container (pan, bucket, etc.), the
unit must be placed at a correct
height.
F
Emptying the condensate
container
The integrated condensate
container must be emptied from
time to time.
Dehumidification mode is switched
off if the condensate container is
full.
The “Container full” indicator light
indicates that the unit has switched
off.
1. Pull the full container forwards
and out carefully.
2. Pour the water into a drain.
3. Re-insert the emptied container
carefully into the unit.
The “Container full” indicator
light extinguishes and the unit
continues to run automatically.
Leakage control device
The unit is equipped with a
leakage control device to prevent
damage in the event of refrigerant
loss.
If the unit detects a leak, the
compressor is switched off. The
fan continues to operate without
interruption in order to prevent an
accumulation of refrigerant.
NOTE
After being emptied, the
condensate container incl. oat
must be checked for damage,
contamination etc.
NOTE
The unit can only be started once
the condensate container has
been inserted correctly.
CAUTION!
There is no unit overflow
protection in this variant.
CAUTION!
Ensure that the drainage hose
is placed at an incline to the
drain to allow the condensate
to drain without hindrance!
CAUTION!
A lack of refrigerant can cause
damage to the unit. If a lack
of refrigerant is detected
(continuous fan operation
when the compressor is
not running), the unit must
be taken out of operation
immediately!
Work on the refrigerant
system and on the electrical
equipment must only be
conducted by a specially
authorised specialist!
The leakage control device
must not be viewed as a
replacement for maintenance
work and damage checks!
NOTE
By switching the compressor
off and on again, the unit
initially continues to run
in normal operation until
the leakage control device
switches the compressor off
again.
