INTRODUCTION
General information
Thank you for purchasing this indoor unit.
The indoor unit is the indoor part of the
reversible air to water Daikin ERHQ heat pumps. These units are
designed for wall mounted indoor installation and used for both
heating and cooling applications. The units can be combined with
Daikin fan coil units, floor heating applications, low temperature
radiators and sanitary water heating applications.
Heating/cooling units and heating only units
The indoor unit range consists of two main
versions: a heating/cooling (EKHBX) version and a heating only
(EKHBH) version.
Both versions can optionally be delivered with an integrated backup
heater for additional heating capacity during cold outdoor
temperatures. The backup heater also serves as a backup in case of
malfunctioning of the outdoor unit. The backup heater models are
available for a heating capacity of 3, 6 and 9 kW, and – depending on
the heating capacity – for three different power supply specifications.

TYPICAL APPLICATION EXAMPLES
The application examples given below are for illustration purposes
only.
Application 1
Space heating only application with a room thermostat connected to
the indoor unit.
Pump operation and space heating
When a room thermostat (T) is connected to the indoor unit, the
pump (4) will operate when there is a heating request from the room
thermostat, and the outdoor unit will start operating to achieve the
target leaving water temperature as set on the user interface.
When the room temperature is above the thermostat set point, the
outdoor unit and pump will stop operating.
Application 2
Space heating only application without room thermostat connected to
the indoor unit. The temperature in each room is controlled by a valve
on each water circuit. Sanitary warm water is provided through the

Sanitary heating
When sanitary heating mode is enabled (either manually by the user,
or automatically through a schedule timer) the target sanitary water
temperature will be achieved by a combination of the heat exchanger
coil and the electrical booster heater.
When the sanitary water temperature is below the user configured
set point, the 3-way valve will be activated to heat the sanitary water
by means of the heat pump. In case of large sanitary water demand
or a high sanitary water temperature setting, the booster heater (10)
can provide auxiliary heating.
Application 3
Space cooling and heating application with a room thermostat
suitable for cooling/heating changeover connected to the indoor
unit. Heating is provided through floor heating loops and fan coil
units. Cooling is provided through the fan coil units only.
Sanitary warm water is provided through the sanitary water tank
which is connected to the indoor unit.
Pump operation and space heating and cooling
According to the season, the customer will select cooling or heating
on the room thermostat (T). This selection is not possible by
operating the user interface.
When space cooling/heating is requested by the room thermostat
(T), the pump will start operating and the indoor unit (2) will switch to
"cooling mode"/"heating mode". The outdoor unit (1) will start
operating to achieve the target leaving cold/hot water temperature.
In case of cooling mode, the motorised 2-way valve (13) will close as
to prevent cold water running through the floor heating loops (FHL).
The ON/OFF setting of the heating/cooling operation is done by the
room thermostat and cannot be done by the user interface on the
indoor unit.
Sanitary heating
Sanitary water heating is as described under "Application 2" on
page 3.
Application 4

Mounting the indoor unit
1Fix the wall mounting bracket to the wall using appropriate plugs
and screws.
Make sure the wall mounting bracket is completely level. When
the unit is not installed level, air might get trapped in the water
circuit resulting in malfunctioning of the unit.
Pay special attention to this when installing an EKHBX model to
prevent overflow of the drain pan.
2Hang the indoor unit on the wall mounting bracket.
3Fix the indoor unit at the bottom side using appropriate plugs
and screws. To do so, the unit is equipped with 2 holes at the
bottom outer edges of the frame.
Installation of the EKHBDP drain pan kit (only for
EKHBX models)
For heating/cooling models, it is necessary to install the drain pan kit
(see "Accessories" on page 2).
During cooling operation, water vapour (humidity) in the air might
condense to liquid and collect on the cold refrigerant and water pipes.
This water is collected in the drain pan, which should be connected to
a drain.
For installation instructions, refer to the instruction sheet delivered
with the drain pan kit.
Refrigerant pipework
For all guidelines, instructions and specifications regarding
refrigerant pipework between the indoor unit and the outdoor unit,
please refer to the outdoor unit installation manual.
The location of the gas pipe and liquid pipe on the indoor unit is
shown under "Main components" on page 6.
Water pipework
Checking the water circuit
The units are equipped with a water inlet and water outlet for
connection to a water circuit. This circuit must be provided by a
licensed technician and must comply with all relevant European and
national regulations.
Before continuing the installation of the unit, check the following
points:
■The maximum water pressure is 3 bar.
■Two shut-off valves are delivered with the unit. To facilitate
service and maintenance, install one at the water inlet and one
at the water outlet of the indoor unit. Mind position of the shut-off
valves. Orientation of the integrated drain valves is important for
servicing. See figure 4.
■Drain taps must be provided at all low points of the system to
permit complete drainage of the circuit during maintenance.
Two drain valves integrated in the shut-off valves, and a drain
valve on the expansion vessel are provided to drain the water
from the indoor unit water system.
■Make sure to provide a proper drain for the pressure relief valve
to avoid any water coming into contact with electrical parts.
■Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible for
servicing. An automatic air purge is provided inside the indoor
unit. Check that this air purge valve is not tightened too much so
that automatic release of air in the water circuit remains possible.
■Take care that the components installed in the field piping can
withstand the water pressure.
The weight of the indoor unit is approximately 55 kg. Two
persons are required to mount the unit.

Checking the water volume and expansion vessel pre-
pressure
The unit is equipped with an expansion vessel of 10 litre which has a
default pre-pressure of 1 bar.
To assure proper operation of the unit, the pre-pressure of the
expansion vessel might need to be adjusted and the minimum and
maximum water volume must be checked.
1Check that the total water volume in the installation is 20 l
minimum.
2Using the table below, determine if the expansion vessel pre-
pressure requires adjustment.
3Using the table and instructions below, determine if the total
water volume in the installation is below the maximum allowed
water volume.
Calculating the pre-pressure of the expansion vessel
The pre-pressure (Pg) to be set depends on the maximum
installation height difference (H) and is calculated as below:
Pg=(H/10+0.3) bar
Checking the maximum allowed water volume
To determine the maximum allowed water volume in the entire circuit,
proceed as follows:
1Determine for the calculated pre-pressure (Pg) the
corresponding maximum water volume using the graph below.
2Check that the total water volume in the entire water circuit is
lower than this value.
If this is not the case, the expansion vessel inside the indoor unit is
too small for the installation.
Example 1
The indoor unit is installed 5 m below the highest point in the water
circuit. The total water volume in the water circuit is 100 l.
In this example, no action or adjustment is required.
Example 2
The indoor unit is installed at the highest point in the water circuit.
The total water volume in the water circuit is 350 l.
Result:
■Since 350 l is higher than 280 l, the pre-pressure must be
decreased (see table above).
■The required pre-pressure is:
Pg = (H/10 + 0.3) bar = (0/10 + 0.3) bar = 0.3 bar
■The corresponding maximum water volume can be read from
the graph: approximately 410 l.
■Since the total water volume (350 l) is below the maximum water
volume (410 l), the expansion vessel suffices for the installation.
Setting the pre-pressure of the expansion vessel
When it is required to change the default pre-pressure of the
expansion vessel (1 bar), keep in mind the following guidelines:
■Use only dry nitrogen to set the expansion vessel pre-pressure.
■Inappropriate setting of the expansion vessel pre-pressure will
lead to malfunction of the system. Therefore, the pre-pressure
should only be adjusted by a licensed installer.
Connecting the water circuit
Water connections must be made in accordance with the outlook
diagram delivered with the unit, respecting the water in- and outlet.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
■Use clean pipes only.
■Hold the pipe end downwards when removing burrs.
■Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
■Use a good thread sealant for the sealing of the connections.
The sealing must be able to withstand the pressures and
temperatures of the system.
■When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
■Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
In most air conditioning applications this minimum water
volume will have a satisfying result.
In critical processes or in rooms with a high heat load
though, extra water volume might be required.
Installation

Be careful not to deform the unit piping by using excessive
force when connecting the piping. Deformation of the
piping can cause the unit to malfunction.
■The unit is only to be used in a closed water system.
Application in an open water circuit can lead to
excessive corrosion of the water piping.
■Never use Zn-coated parts in the water circuit.
Excessive corrosion of these parts may occur as
copper piping is used in the unit's internal water
circuit.
NOTE ■When using a 3-way valve in the water circuit.
Preferably choose a ball type 3-way valve to
guarantee full separation between sanitary warm
water and floor heating water circuit.
■When using a 3-way valve or a 2-way valve in the
water circuit.
The recommended maximum changeover time of
the valve should be less than 60 seconds.

Charging water
1Connect the water supply to a drain and fill valve (see "Main
components" on page 6).
2Make sure the automatic air purge valve is open (at least 2
turns).
3Fill with water until the manometer indicates a pressure of
approximately 2.0 bar. Remove air in the circuit as much as
possible using the air purge valves. Air present in the water
circuit might cause malfunctioning of the optional backup heater.
4For units with optional backup heater:
Check that the backup heater vessel is filled with water by
opening the pressure relief valve. Water must flow out of the
valve.
Piping insulation
The complete water circuit, inclusive all piping, must be insulated to
prevent condensation during cooling operation and reduction of the
cooling and heating capacity.
If the temperature is higher than 30°C and the humidity is higher than
RH 80%, then the thickness of the sealing materials should be at
least 20 mm in order to avoid condensation on the surface of the
sealing.
Field wiring
Overview
The illustration below gives an overview of the required field wiring
between several parts of the installation. Refer also to "Typical
application examples" on page 3.
NOTE ■During filling, it might not be possible to remove all
air in the system. Remaining air will be removed
through the automatic air purge valves during first
operating hours of the system. Additional filling
with water afterwards might be required.
■The water pressure indicated on the manometer
will vary depending on the water temperature.
(higher pressure at higher water temperature).
However, at all times water pressure should

SANITARY WATER TANK (OPTIONAL)Following descriptions are only for EKSWW*V3
models, not for EKSWWU*V3 models.
Main components
■The total system (indoor unit and
outdoor unit) is designed for combination with an
sanitary water tank. In case
another tank is being used in combination with the
indoor unit, Daikin cannot
guarantee neither good operation nor reliability of the
system. For those reasons Daikin cannot give
warranty of the system in such case.
■Sanitary water quality must be according to EN
directive 98/83 EC.
■For safety reasons, it is not allowed to add ethylene
glycol to the water circuit. Adding ethylene glycol
might lead to contamination of the sanitary water if a
leakage would occur in the heat exchanger coil.
■It is important that the storage capacity of the sanitary
water tank meets normal daily fluctuations in
consumption of hot water without any fall of the water
outlet temperature during use.
■Immediately after installation, the sanitary water tank
must be flushed with fresh water. This procedure must
be repeated at least once a day the first 5 consecutive
days after installation.
■In case of limited consumption of hot water, e.g. at
holiday residences or at houses that are occasionally
not occupied, the sanitary water tank installation must
be fitted with a shunt pump.
- The shunt pump can be time-controlled,
- the shunt pump must operate to circulate the
complete volume of the sanitary water tank 1.5
times per hour,
- and the shunt pump must operate, or be
programmed for operation, during 2 uninterrupted
hours per day at least.
NOTE For installation of an EKSWWU sanitary water tank,
refer to the installation manual supplied with the
EKUSWW installation kit.

START-UP AND CONFIGURATION
The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user expertise.
DIP switch settings overview
DIP switch SS2 is located on the switch box' PCB (see "Switch box
main components" on page 7) and allows configuration of sanitary
water tank installation, room thermostat connection and pump
operation.
Room thermostat installation configuration
The following table summarizes the required configuration and
thermostat wiring at the terminal block in the switch box. Pump
operation is listed in the third column. The three last columns indicate
whether the following functionality is available on the user interface
(UI) or handled by the thermostat (T):
• space heating or cooling on/off (y)
• heating/cooling changeover (=)
• heating and cooling schedule timers (pr)
Pump operation configuration
Without room thermostat
When no thermostat is connected to the indoor unit, pump operation
will be determined by the leaving water temperature.
To force continuous pump operation when no room thermostat is
connected do the following:
- set toggle switch SS2-3 to ON,
- short-circuit the terminal numbers 23-17-13 on the terminal
block in the switch box.
With room thermostat
When a thermostat is connected to the indoor unit, the pump will
operate continuously whenever there is heating or cooling demand
requested by the thermostat.
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.
Switch off the power supply before opening the switch box
service panel and making any changes to the DIP switch
settings.
