This is how the dryer works
The integrated fan (7) circulates the room air through the dryer. When the moist air passes through
the evaporator (2) it is cooled down to dew point and condensation water is deposited. The water
runs down into the collection receptacle via a condensation filter (4). The condensation water is
evacuated from there automatically by the integrated water pump (8), which can manage a height of
up to five metres. The pump runs continuously and if it does not manage to drain the water because
of a pinched hose or other fault, the overflow sensor (5) activates, which stops the machine.
The dry and cold air then goes through the condenser (3) where it is heated, partly by the compressor
heater (6) and partly by the energy recovered during the previous transformation of water vapour to
water. The dry and hot air is then blown into the premises again.
For optimal operation, machine defrosting is demand controlled and is only activated when the
temperature and humidity conditions are such that frost forms on the cooling coil.

Electrical connection
The machine is connected to the earthed 230V/50Hz socket. K3 ES HP can be connected to a 10A,
max 16A, fuse.
Electronic control delays the start max 2 minutes.
Starting and operating
•Operating range humidity: 30-100% RH
•Operating range temperature: +9°C to +38°C
•The dryer must reach ambient temperature before starting, if stored in colder conditions.
1. Place the dryer on a firm and flat surface where it is not at risk of overturning. The surface
should not be sensitive to water as some spillage may occur, for example when handling the
condensation water hose.
2. The dryer must be placed at a distance of at least half (0.5) a metre from walls and ceilings to
ensure that air can circulate.
3. If possible, close doors and windows etc. to use all the dehumidification capacity in the
intended space rather than to dry the whole house/building. To minimise power
consumption, try to ensure that the ambient temperature is approximately 20°C.
4. The dryer's hose for condensation water is routed to a drain, sink or similar frost-free runoff
for continuous operation.
5. The ambient temperature must be +9°C to +38°C.
6. K3 ES HP is equipped with demand controlled defrosting. If ice forms on the evaporator, the
dryer defrosts automatically by stopping the machine. The machine restarts automatically
when the evaporator is clear of ice.
For use on sensitive surfaces, note the following:
When the machine is turned off, any frost on the evaporator thaws and, if there is a lot of frost, this
can cause spillage because the pump is off.

User instructions ES product family
Intended use
The adsorption dehumidifiers in the ES range have been developed and designed for drying water
damage and building moisture. The dehumidifiers can be used freestanding or in combination with
turbines, for pressure and suction drying of a layered construction for example.
Via the control panel, the user of K3 ES HP can optimise the operation for the intended job, set the
capacity and volume, control the fan as well as use integrated or external sensors for temperature
and relative humidity to achieve the desired effect in combination with the lowest possible energy
consumption. K3 ES HP can also be used in networks and is prepared for remote monitoring and
remote control. The unit also has folding handles with holders for the electrical cable and the hose,
while its light weight means it is easy to carry and install. The durable but flexible feet protect the
floor surfaces and also make it possible to stack the machines. The dehumidifiers have a naturally
robust construction that gives a long service life.
ES product family, menus and operation
K3 ES HP has an easy-to-use user interface with a display and five buttons. The two larger buttons on
each side of the display are used to select between different menus. These buttons are only intended
for navigation and cannot be used to change the settings.
The three smaller buttons are used for selection and editing and their functions are always presented
as text at the bottom of the screen. On the upper menus, the left-hand button is called the HOME
button. One push of this button takes you straight back to the standard view. In many of the views
there is an Info button that presents information that can be useful for inexperienced users.
If the display's background lighting goes out after the preset time, the first button push only
illuminates the display.
If no button is pushed for ten minutes, a keylock is activated. The machine then must be unlocked by
pushing the two-upper button simultaneously. This procedure is presented as text and as an image
on the display.
Upper buttons to the left and right –Only menu navigation. Never change
any settings.

Control mode
In control mode, it is determined whether drying
should occur continuously (MAN - manual mode)
or is only to be activated when necessary, on the
basis of the ambient climate.
The selected control mode is displayed in the
lower, left-hand corner in standard view.
Open the screen for selecting control mode by
pressing the upper, right-hand button.
The following basic control modes are available:
MAN
Manual, continuous drying.
RH
Dehumidification for selectable
relative humidity (%).
X
Dehumidification for selectable
mixing ratio (g/kg).
DP
Dehumidification for selectable dew
point (°C).
HYG
Dehumidification is controlled by an
external hygrostat that is connected
to the machine.
Thanks to its network functions, you can also
connect the machine to external temp. and RH
sensors, and use their values to control
operation, instead of the built-in sensor for
relative humidity and temperature. The
following modes for external sensors exist for
this purpose:
E.RH
Dehumidification for selectable
relative humidity (%) according to
the input values from the external
temp and RF sensor(s) that are
connected to the machine.
E.X
Dehumidification for selectable
mixing ratio (g/kg), according to the
input values from the external
sensor(s) that are connected to the
machine.
E.DP
Dehumidification for selectable dew
point (°C), according to the input
values from the external sensor(s)
that are connected to the machine.
The external control mode requires that the
machine is network connected and connected to

an external temp. and RH sensor. If the machine
is not already connected to the network, the
machine asks whether to create a network.
If there are several sensors in the network and if
the <All> option has been selected (instead of a
single sensor, e.g. RHT61) the machine works on
the "worst case scenario" and runs for as long as
any of the sensors detects that the humidity is
above the setpoint.
If the machine selects a mode other than MAN,
the user will note that the setpoint can be set.
When the setpoint has been reached, drying
stops automatically. If the humidity later rises
above the setpoint again, drying resumes
automatically.
Hysteresis
When one of control modes; RH, DP or X is
selected, a symbol and a hysteresis value
appears to the right of the display.
The symbol shows the setpoint value's position
in the operation range as below.
↕ - centre
↓ - bottom
↑ - top
Capacity mode
The drying capacity of K3 ES HP can be optimised
for a given work task and situation with three
different operating modes.
When setting MAX (maximum) the machine
works to remove as much water as possible. If
the machine's total power is not required, it can
instead be set to ECO (eco-mode) where the
energy consumption per litre of removed water
is minimised.
For localised water damage where the dry air
quantity is not required, the machine can be set
to ΔX (ΔX mode). In this mode, the machine
produces a smaller amount of even drier air that
further accelerates the drying process.
MAX
For maximum capacity.
•High fan speed
•Min temp 9°C
•Max temp 38°C
•RH min 0 %

ECO
For minimal energy
consumption per litre of
removed water.
•High fan speed
•Min temp 14°C
•Max temp 38°C
•RH min 35 %
ΔX
For maximum ΔX, as dry air as
possible. Reduced air amounts
suitable for e.g. local, isolated
water damage.
•Low fan speed
•Min temp 9°C
•Max temp 38°C
•RH min 0 %
Timer
K3 ES HP has an integrated timer function that
allows the user to determine when the machine
is to run. When the timer function is used, the
word Timer appears in the standard view's
upper, right-hand corner according to the
graphic to the right.
Activate the timer by pressing the right-hand
arrow button four times to open the timer
menu.
Press Activate.
When the timer has been activated, the machine
begins by prompting the user to check that the
time and date have been set correctly. If they
have been, press OK. If the time or date need
changing, press Edit and adjust the values before
continuing.
In the next step the user can set the time
interval that the machine is to work within. The
machine remembers the timer settings from the
previous time it was used and shows its settings
as the start values.
The Other time setting determines whether the
machine, during the day's remaining hours, must
be in standby mode or run at lower fan speed
for minimal noise.

Network
Note! Install all system cables before the
machines are started.
K3 ES HP has network functions that enable local
interaction between machines, for example
pressure drying and use of external sensors for
relative humidity and temperature control of the
machine. The network functions also prepare
the machine for a future SuperVision system
that will allow remote monitoring and remote
control of the machines via Internet.
A network is established by installing the
machines in the intended way and connecting
them to each other using system cables before
they are started.
Open the network menu on the machine which
is to be master, i.e. control the others.
Press Create and wait while the machine
establishes the network. This can take up to one
minute.
Once the network has been established, the
display switches between the slave units in the
network menu. These are indicated by type (e.g.
A4) and bus address (e.g. 101).
To change the settings for a slave unit, press
Change and select the slave unit. The
background lighting for the selected unit starts
to flash to confirm that the unit has been
selected.
Desired settings can also be made directly on the
relevant machine.
Start the master machine when all desired
settings have been made. The slaves start
automatically within one minute. The machines
are stopped in the same way. Press stop on the
master machine and the slaves stop
automatically shortly afterwards.
As the network is controlled by the master
machine, a slave unit that is started manually is
stopped when the master machine is in standby.
In the same way, a slave unit that is stopped
manually is restarted manually when the master
machine is in operation.
