REMKO SLE series

It is evident that the corrosion
rate below 50 % relative humidity
(RH) is low, and below 40 % is
negligible.
The corrosion rate increases
significantly 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 dehumidification:
The moist air that is present
within an enclosed space is
continuously dehumidified
according to the condensation
principle.
The correlations occurring when
air is dehumidified 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 dehumidification.
The use of
REMKO air dehumidifiers
– 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 diffused after 1-2 months.
– Even moisture trapped in the
masonry after high-water or
a flood 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 different levels of humidity.
Air dehumidification
Relative humidity %
Corrosion rate
With regard to energy
consumption, air dehumidification
has one distinct advantage:
Energy expenditure is limited
exclusively to the air volumes
present. The mechanical heat that
is released by the dehumidification
process is fed back into the room.
Under normal use, the
air
dehumidifier
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 specified in g per kg of
dry air (absolute moisture content).
1 m3of 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.
5

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 the 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.
It then condenses to water.
Humidity is then 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.
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 effected 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 REMKO air dehumidifier.
The air is dehumidified 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
off from there.

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 it 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.
When dehumidifying, 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.

Testing the water quality
Water quality
The correct combination of chemicals in swimming pools in indoor areas is of major importance to the health of
the users and for systems in the vicinity of the swimming pool and its plant room.
Inadequately treated water leads to poor hygiene, whilst water that has been excessively treated gives off
chlorine into the air, which can irritate the eyes and lead to respiratory problems. At the same time, an incorrect
combination of chemicals in the water can lead within a very short time to the destruction of all systems -
including the dehumidifier and other systems that have been installed for air treatment.
The following tables contain the limit values for swimming pools in indoor areas in accordance with
EN/ISO 12944-2, corrosivity category C4.
These limit values must be observed, otherwise the guarantee is voided
When adding chemicals
The following guideline values apply to swimming pools when adding chemicals:
Chemical values ppm
Free chlorine content 1,0 - 2,0
Combined chlorine content max. 1/3 of the free chlorine content
pH value 7,2 - 7,6
Total alkalinity 80 - 150
Calcium hardness 250 - 450
Total dissolved solids < 2000
Sulphates < 360
With own production of chlorine
The following guideline values apply to swimming pools with own production of chlorine:
Chemical values ppm
Salt (NaCl) < 30000
Total dissolved solids < 5 500
pH value 7,2 - 7,6
Total alkalinity 80 - 150
Calcium hardness 250 - 450
Sulphates < 360
Langelier saturation index
To make sure the various water quality parameters remain within an acceptable range, the Langelier saturation
index should be applied.

Unit description
Schematic depiction of the workings of the SLE 45-85 air dehumidifier
Moist room air
Warmed and
dehumidified air
The units may be used
to dehumidify areas such as:
■ Private swimming pools
■ Spa areas
■ Fitness centres
■ Storage rooms
■ Archives
■ Museums
The units have been designed for
universal and straightforward air
dehumidification.
Their compact dimensions allow
the units to be transported and
installed with ease in the adjacent
room.
The units operate in accordance
with the condensation principle
and are equipped with a
hermetically sealed refrigerant
system and low-noise and low-
maintenance fan(s).
The fully-automated electronic
controller, an integrated hygrostat
and connection ports for
condensate drainage provided by
the customer ensure continuous
fault-free operation.
The units are reliable, easy to use
and conform to the fundamental
health and safety requirements of
the appropriate EU stipulations.
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.
Operating sequence
The unit is switched on and off
using the integrated hygrostat.
The hygrostat is set to
60 % RH in the factory.
The respective unit function is
indicated by a multi-colour LED
display on the front of the unit.
The fan extracts the moist room
air via the lower part of the front
panel.
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, the cold and
dehumidified air is warmed up
again and discharged back into the
room via the top part of the front
panel with a temperature increase
of around 5 K above the room
temperature.
The processed, dry air therefore
continuously 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.
LED light function
If the unit was delivered with the
LED light function, the light can
be switched on and off using an
operating switch at the top right
corner of the panel. If designed as
an RGB-LED, a remote control is
also supplied.

Condensate water drain
The condensate water drain is
located on the unit's base.
The condensate drain is connected
to the discharge nozzle supplied.
A solid or flexible 3/4” discharge
connector can be installed on this.
■ The discharge hose must always
be laid at an incline of at least
2 % so that the water can flow
unhindered from the drip tray.
■ Alternatively, a condensate
pump can be fitted to the unit in
order to pump the condensate
water to a drainage point
located at a higher level.
■ If drainage is to be carried out
through the wall, the relevant
measures such as holes for
correct condensate drainage
must be taken before installing
the unit.

Before commissioning the unit or if
local requirements dictate, the air-
inlet grill and air-outlet grill must
be checked for contamination.
The units are operated using an
integrated hygrostat that is set to
60 % RH (default value for spas
and indoor swimming pools).
If the room humidity is below
60 % RH, the unit does not start.
If the relative humidity is
above 60 %, the unit starts
the dehumidification process
automatically.
If you would like to make changes
to the hygrostat settings, remove
the front panel and the control
board cover located in the upper
section in order to access the
control board.
Commissioning
NOTE
When the unit is switched on
or off using the main switch,
a signal is issued upon startup
and the operation LED display
illuminates blue as soon as
the unit is ready for operation.
Once all conditions have
been met, the dehumidifying
process begins.
Display and operator panel
The display is a four-digit seven
segment display. The first two
digits are used to display the
respective “code”, e.g. rHXX, for
setting the room humidity and the
last two digits correspond to the
value set.
In the standard view, no code is
shown on the display. It is only the
value of the humidity currently
measured that is displayed.
The operator panel with the
buttons “Up”, “Down” and
“OK” can be found on the right-
hand side of the front of the
control board. These can be used
to navigate around the menu
structure of the control board and
to couple the control board with
a wireless remote control.
NOTE
If the air humidity is lower
that the set value, the unit will
not start up, even if the mains
voltage is connected.
Control board, front
Control board
The units are equipped with an
electronic controller. This features
various interfaces and a display.
The following section describes
these features in detail.

NOTE
Interrupting the operation of
the unit before the compressor
has run for 6 minutes will
activate a restart lock lasting
approx. 4 minutes.
EXT RH/T
These terminals allow you to
connect up an external electronic
humidity and temperature probe.
The temperature probe must be
an NTC probe with 10 kΩat 25
°C and a B25/85 of 3969 K. The
humidity probe must be designed
for a voltage supply of 12 V DC and
feature an analogue voltage output
of 0-10_V with max. 10 mA.
ALARM
The alarm contacts are two
potential-free contacts that are
open in an unswitched state.
The RUN contact is closed when the
compressor is in operation.
The FAIL contact is closed when
there is a malfunction in the unit.

reaching the specified air humidity
more quickly. The set value may
differ from the setpoint humidity
so that the external heating can
either operate permanently or
merely provide a support function.
The value can be set between
40 and 99 % RH. The default
value is set to “OF”.
Code: SI
The code “SI” stands for the
maintenance interval that the
operator or fitter requires. This
value is indicated in weeks and can
be set from 01 to 99. The default
value is “OF.”
Code: tE
The code “tE” stands for testing
and the value “St” for self-test.
To start the self-test, press “OK”
and to cancel it, hold the down
key down for 5 seconds.
Menu structure
To define the setpoints using the
integrated operator panel, hold
down the “OK” key for 5 seconds
so that the display switches from

Fan control
When the control board puts the
dehumidifier into operation, the
fan(s) switch on together with the
compressor.
Defrosting
The units feature an intelligent and
active defrosting function. If the
room temperature is below 20 °C,
the evaporator will start to ice up
after a short time.
If the evaporator probe registers
a temperature of less than 5 °C
on the evaporator surface,
the unit only continues to run
in dehumidification mode for
a further 30 minutes.
Once this time has expired, the
fans stop and the solenoid valve
for hot-gas defrosting opens.
When the evaporator probe
registers a temperature higher
than 5 ºC again, the solenoid
valve closes and the unit resumes
dehumidification.
Safety circuit
If the temperature exceeds 55 °C
on the condenser (e.g. due to a fan
failure or an overly high room
temperature (higher than 36 °C)),
the compressor stops automatically
to prevent an overload.
As soon as the temperature on the
condenser permits dehumidification
again, the unit starts up
automatically.
Unit function
Compressor control
The compressor has a 6 minute
restart delay. The delay period
must elapse before it is possible to
restart the compressor.
This safety function protects the
compressor against an overload
caused by overly high pressure
in the cooling cycle.
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 via the mains power
supply.
The compressor does not switch
back on until after a waiting time
of approx. 30 seconds!
Operating LED
The multi-colour LED display is in
the background of the top grille
on the front panel. It indicates the
current operating state of the unit.
Legend of the operation LED colours
The LED illuminates “blue” and
stays that way when the unit is
connected to the mains power
supply (standby).
The LED illuminates “green”
and stays that way when the
compressor is in operation and
the unit is in dehumidifying or
defrosting mode.
The LED lights up “yellow” and
stays that way when the unit
is operating in wireless remote
control mode.
The LED lights up “red” when
a fault has occurred. Please refer
to the Troubleshooting chapter to
rectify the fault.
LED light function
If the unit was delivered with the
LED light function, the light can
be switched on and off using an
operating switch at the top right
corner of the panel. If designed as
an RGB-LED, a remote control is
also supplied.

3. If coupling was successful, the
unit sends a serial number to the
wireless remote control and the
wireless symbol is displayed.
4. The swimming pool
dehumidifier confirms the
connection by displaying the code
“Conn” for a period of 3 seconds.
This procedure can also be carried
out using several remote controls
so that an air dehumidifier can
be controller by several remote
controls.
Connecting the antenna
The antenna is located on the
control board inside the unit or
can be fitted there. This will be
pre-installed if the unit is delivered
together with the remote control.
Before fitting the antenna,
disconnect the unit from the
power supply. Then loosen the two
locks on the bottom of the unit by
turning them anticlockwise, tilt the
front cover of the unit and lift it
up. In the upper right area, remove
the two screws on the board cover
and remove the cover. Pull the
control board forwards, screw
the antenna into place and bend
it forwards. Once the antenna is
screwed in place and the board
has been returned to the previous
position, the unit can now be
provided with power in order to
couple it with the wireless remote
control. Then screw the housing
parts back into place.
Switching on and coupling the
remote control
The wireless remote control must
be coupled with the unit before it
can be used. To do so, carry out
the following steps.
1. Insert the batteries provided into
the battery compartment on the
rear of the wireless remote control.
2a. The remote control will search
for the unit for two minutes.
During this time, the remote
control display flashes every
2 seconds.
2b. During the search phase, hold
down the Up and Down keys on
the operator panel of the control
board at the same time for 5
seconds.

Coupling failure
If the wireless remote control fails
to couple with the unit, the fault
symbol becomes visible, “Conn” is
shown permanently on the display
and the wireless symbol flashes.
The wireless remote control
needs to be reset before a new
coupling attempt can be made.
To do so, hold the Left key on the
wireless remote control down for
10 seconds.

Maintenance message
Unlike the other fault messages,
the maintenance message can
be acknowledged or reset via the
wireless remote control. This is
due to the fact that it is a purely
informative message.
Proceed as follows to set up the
new maintenance interval.
1. Hold down the Right key for
5 seconds to open the fitter menu.
2. Use the Up and Down keys
to navigate to the maintenance
symbol.
3. Use the Right and Left keys to
change the 0 value to the required
maintenance interval.
4. Confirm the new maintenance
interval by pressing the Enter key.
Fault messages
The fault messages correspond
to the alarm messages which can
also be shown on the unit’s control
board display. To make the alarm
message recognizable, the fault
symbol is also displayed on the
wireless remote control.
Generally speaking, the fault
messages can only be reset on the
display panel of the control board.
The unit must be thoroughly
inspected and the fault reset
following rectification each and
every time.
No changes can be made to the
setpoints in the setup menus while
there is an active fault.
User setup menu
Hold down the Enter key for
3 seconds to open the user setup
menu.
In this menu it is possible to switch
between the wireless remote
control symbols using the Up
and Down keys provided the
corresponding option of “OF” has
been set to a value on the control
board itself. Please read pages 12
and 13 to set these values.
The Left and Right keys can be
used to set these parameter values.
The parameter is confirmed as
a new setpoint using the Enter
key. When this is confirmed, the
remote control switches back to
the symbol and exits the menu.
If you would like to exit the user
setup menu, do not press any
keys on the remote control for
10 seconds.
