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.

Page 11

2017.07

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.

Start view

When K5 ES HP PX starts up, two options appear for the user on the display:

Start: Starts the machine with standard settings, continuous operation with maximum capacity. Previous settings such as use of sensor control, timer etc.

Resume: The machine resumes operation with the same settings that previously applied.

If the user did not press the stop button before the power was interrupted the last time the machine was used, the machine will automatically resume operation when the timer has counted down to zero. The countdown can be stopped by pressing the Stop button, which then switches the machines to standby until it is started manually.

Normal start

Start after power cut –

automatic resumption of operation

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. Also shown here is whether the machine is defrosting and if it has stopped and gives an alarm for too high or too low ambient temperature.

In the event of a dehumidification process stoppage, the fan runs-on for post cooling for 120 seconds.

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.

Dehumidification for selectable relative humidity (%).

Dehumidification for selectable mixing ratio (g/kg).

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

Page 16

2017.07

14 (31)

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

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.

Page 18

2017.07

16 (31)

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.

Page 19

2017.07

17 (31)

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.
