The integrated fan (9) 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 bucket (7) via a condensation filter (4). The condensation water is evacuated from
there automatically
by the integrated water pump (10), 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 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. K5 ES HP PX 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: +3°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
bucket and condensation water hose.
2. The dryer can be positioned against a wall as illustrated. In all other cases, 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. If using a condensation water hose, ensure that it is routed to a drain, sink or similar frost-
free runoff for continuous operation.
5. The ambient temperature must be +3°C to +38°C.
6. K5 ES HP PX is equipped with demand controlled defrosting. If ice forms on the evaporator,
the dryer defrosts automatically with help from hot gas defrosting. The machine resumes
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 K5 ES HP PX 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. K5 ES HP PX can also be used in networks and is prepared for remote
monitoring and remote control. The unit has a folding carry handle designed for both pulling the
machine along the ground and for lifting it. It also has handles with holders for the electrical cable
and the hose, while its light weight means it is easy to carry, roll 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
K5 ES HP PX 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.

Standard view
When K5 ES HP PX is in operation, the machine can
always be stopped (set to standby) using the middle
button below the display.
When the machine is running in a control mode instead
of in manual mode, the setpoint (which is marked with
black background in the middle of the screen) can be
increased or decreased using the negative (-) and
positive (+) buttons.
When the compressor has stopped, the start is delayed
for at least 120 seconds. The remaining time until start
appears in the round circle to the left.

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.

Capacity mode
The drying capacity of K5 ES HP PX 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
•Hot gas defrosting
•Min temp 3°C
•Max temp 38°C
•RH min 0 %
ECO
For minimal energy consumption per
litre of removed water.
•High fan speed
•Stop defrosting
•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
•Hot gas defrosting
•Min temp 3°C
•Max temp 38°C
•RH min 0 %
Extra heater K5 ES HP PX
K5 ES HP PX is equipped with an additional heater that
increases the dry air temperature and thus improves
the drying effect further.
When this function is selected, an icon for the extra
heater appears below the fan symbol in standard view.
The extra heater is of course only active when the fan is
active.
Note! The extra heater may not be used if dry air is fed
into another machine, because it can overheat.

Timer
K5 ES HP PX 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.
K5 ES HP PX 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.
Setup and maintenance menus
The setup and maintenance menus contain functions
that are not needed for normal operations.
Date and time: Setting system date and system time:
The format is YY:MM:DD / HH:MM.
