3. INTRODUCTION

3.1. General information

This installation manual concerns Daikin Altherma air to water
inverter heat pump units of the Daikin EKHVMRD and EKHVMYD
series.

These units are intended for indoor installation and aimed for
apartment or other multi user buildings.

The unit is designed for floor standing heating operation. The
EKHVMYD units can also perform cooling operation. The heat taken
from the indoors' during cooling operation can be stored in the
domestic hot water tank (=heat recovery operation).

EKHVMRD units can only perform heating operation.

EKHVMRD units have heating capacity ranges of 5.6 kW and 9 kW.

EKHVMYD units have heating capacity ranges of 5.6 kW and 9 kW
and cooling capacities of 5 kW and 8 kW.

The indoor units are designed to work in heating and cooling mode at
indoor ambient temperatures from 5°C to 30°C.

During heating operation, the unit can heat up the water to
temperatures of 25°C to 80°C.

During cooling operation (only for EKHVMYD) the unit can cool down
the water to temperatures of 5°C to 20°C.

3.2. Combination and options

The EKHVMRD and EKHVMYD units can only be combined with an
outdoor EMRQ unit.

During heating operation, the unit can be combined with space
heating radiators (field supply), fan coil units (option or field supply) or
floor heating (field supply).

During cooling operation, the unit can be combined with fan coils
(option or field supply).

The remote controller with room thermostat functionality is standard
supplied with this unit to control your installation.

Domestic hot water tank (option)

An optional EKHTS200AB or EKHTS260AB domestic hot water tank
can be connected to the indoor unit. The domestic hot water tank has
a water volume of 200 l or 260 l.

Refer to the domestic hot water tank installation manual for further
details.

Heat pump convector (option)

An optional FWXV convector for cooling or heating operation can be
connected to this indoor unit.

Refer to the heat pump convector installation manual for further
details.

Remote controller (option)

An optional secondary EKRUAHT remote controller (with room
thermostat functionality) can be connected to the indoor unit.
Purpose is to provide the possibility to install the standard remote
controller near the unit (for service reasons), and install another
remote controller in another place (e.g. living room) to operate your
installation.

Refer to "Installation and connection of the remote controller" on

page 31 for further details.

Room thermostat (option)

An optional room thermostat EKRTR or EKRTW can be connected to
the indoor unit.

Refer to the room thermostat installation manual for further details.

Heater kit (option)

An optional EKBUH heater kit can be combined with the indoor unit.
Purpose is to provide an additional heating capacity during cold
outdoor temperatures. The heater kit has a heating capacity of 6 kW,
and available for both 1-phase and 3-phase power supply
specifications. When using this heater kit, installation of the optional
demand PCB is required as well.

Refer to the heater kit installation manual for further details.

Digital I/O PCB (option)

An optional EKRP1HBAA digital I/O PCB can be connected to the
indoor unit and be used to remotely monitor your system. This
address card offers 2 voltage free outputs and 1 high voltage
(230 V AC) output.

Refer to the operation manual of the indoor unit and to the digital I/O
PCB installation manual for more information.

Refer to the wiring diagram or connection diagram for connecting this
PCB to the unit.

Demand PCB (option)

An optional EKRP1AHTA demand PCB can be connected to the
indoor unit. This PCB is needed when the optional heater kit EKBUH
or Daikin room thermostat EKRTR or EKRTW is installed or when
multiple set point control is used, and provides the communication
with the indoor unit.

Refer to the demand PCB installation manual for further details.

Refer to the wiring diagram or connection diagram for connecting this
PCB to the unit.

Individual billing system (field supply).

The Daikin Altherma system uses a common outdoor unit for the
different indoor units. Depending of local regulations, the customer is
free to choose the allocation method of the common electrical power
consumption costs of the outdoor unit.

Daikin advises an allocation method based on the measurements of
consumed heat of each indoor unit. In other words, the outdoor unit
energy input is allocated according the indoor unit energy output. An
individual billing system calculation tool is available on demand.
Contact your local dealer.

Refer to "6. Design of the water circuit" on page 11 for further details.

Cooling output (field supply)(only for EKHVMYD)

This is a 230 V AC output (maximum 0.3 A) which is on during
cooling operation. This can be used to connect a valve which shuts
off radiators to avoid sweat during cooling operation. Refer to

"6.4. Application examples for reversible units" on page 15.

If this option is installed it is not possible to use the remote
controller thermostat function.

The purpose of this chapter is to give guidelines for the design of the
water circuit.

Precautions and guidelines that have impact to the unit prescribed in
this manual are included into this chapter.

Actions needed during the installation of the unit prescribed in this
manual are described in the chapter "7.6. Water piping" on page 25.

WARNING

It is strongly recommended to install an additional filter on
the heating water circuit. Especially to remove metallic
particles from the field heating piping, it is advised to use a
magnetic or cyclone filter which can remove small
particles. Small particles can damage the unit and will not
be removed by the standard filter of the heat pump unit.

6.1. Selection of the type of heat emitters

The selection of the heat emitter is the choice of the end customer.
The choice of the heat emitter will define the needed water
temperature from the unit.

For heating mode

Based on the needed water temperature for the heat emitters,
following range can be defined:

1. Low temperature (Leaving water temperature range from 25°C

to 40°C).
Typical example: floor heating.

2. Medium temperature (Leaving water temperature range from

40°C to 55°C).
Typical example: low temperature radiators or convectors.

3. High temperature (Leaving water temperature range from 55°C

to 75°C).
Typical example: radiators.

For cooling mode

Fan coil units are advised as heat emitters.

NOTE

In a house a combination of the above mentioned heat emitters is
possible.

Once the heat emitters are chosen, the capacity of these heat
emitters should be defined and from this the dimensioning and
position of the heat emitters in the different rooms should be decided.

An important parameter of the heat emitters is the temperature
difference between entering water and leaving water.

This will define the water flow in the system.

Finally, the piping layout from the heat source to the different heat
emitters needs to be drawn.

This will finally define following important parameters:

■ Minimal water volume in the system.

■ Maximal water volume in the system.

■ Minimal and maximal water flow in system.

■ Maximal pressure drop in the system.

■ If floor cooling is used, it is the responsibility of the

installer to take the needed precautions to avoid
floor sweating.

■ The draining of the fancoil units are the
responsibility of the installers.

■ When radiators are used, a shut-off valve must be
installed to avoid sweating of the radiators. (Refer
to "6.3. Application examples for heating only

units" on page 13).

2 Balancing bottle
3 High external static pressure pump
4 High external static pressure system

In refurbishment applications, the water system will
already be fixed. It is utmost important for these kind of
installations to know the parameters mentioned above.

6.2. General precautions concerning water circuit

Before continuing the installation of the unit, check the following
points:

■ The maximum water pressure is 4 bar.

■ The maximum water temperature is 80°C.

■ Provide adequate safeguards in the water circuit to be sure that

the water pressure will never exceed the maximum allowable
working pressure (4 bar).

■ Shut-off valves from flexible hoses delivered with the unit should
be installed so that normal servicing can be accomplished
without draining the system.

■ Drain taps must be provided at all low points of the system to
permit complete drainage of the circuit during maintenance or
service to the unit. A drain valve is provided in the unit to drain
the water from the unit water system.

■ Be 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 shall 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 and temperature.

■ Always use materials which are compatible with the water used
in the system and with the materials used on the unit.

■ Select piping diameter in relation to required water flow and
available ESP of the pump.

When designing the hydraulic system always consider the available
static pressure of the indoor unit.

NOTE

■ The ESP curves are the maximum ESP curves for
different ΔT types (pump rpm=4000 for ΔT=5°C;
pump rpm=3600 for ΔT=10°C). The pump of the
indoor module is inverter controlled and controls
to have a fixed ΔT between return and leaving
water temperature.

■ In case of installing a domestic hot water tank
there is an additional pressure drop over the
3-way valve (delivered as accessory with the
tank).

NOTE

When replacing an old gas or oil boiler by an air to
water pump system:

■ please always check the specifications of the
pump of the old unit;

■ if the external static pressure of that pump is
higher than the external static pressure of the air
to water pump system, please install an additional
pump with higher external static pressure in
combination with a balancing bottle.

3 421

Check that the total water volume in the installation, excluding the
internal water volume of the unit, is 20 l minimum.

WARNING

In most applications this miminum 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

When circulation in each space heating/radiator loop is
controlled by remotely controlled valves, it is important that
this minimum water volume is kept even if all the valves are
closed.

7. INSTALLATION OF THE UNIT

7.1. Selecting an installation location

WARNING

Be sure to provide for adequate measures in order to
prevent that the unit be used as a shelter by small animals.

Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean and clear.

General precautions on installation location

Select an installation site that meets the following requirements:

■ The foundation must be strong enough to support the weight of
the unit. The floor is flat to prevent vibrations and noise
generation and to have sufficient stability.
This is especially of importance when the optional domestic hot
water tank is installed on top of the unit.

■ The space around the unit is adequate for maintenance and
servicing (refer to "Service space of the unit" on page 21).

■ The space around the unit allows for sufficient air circulation.

■ There is no danger of fire due to leakage of inflammable gas.

■ The equipment is not intended for use in a potentially explosive

atmosphere.

■ Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location
is selected according the applicable legislation.
If the sound is measured under actual installation conditions, the
measured value will be higher than the sound pressure level
mentioned in "13. Unit specifications" on page 59 due to
environmental noise and sound reflections.
Choose the installation location carefully and do not install in a
sound sensitive environment (e.g. living room, bedroom, …)

■ All piping lengths and distances have been taken into
consideration (For requirements of piping length for the
refrigerant piping, refer to the outdoor unit installation manual).

Requirement Value

Maximum allowable distance between the domestic
hot water tank and the indoor unit (only for
installations with domestic hot water tank).

10 m

NOTE

If the installation is equipped with a domestic hot water
tank (optional), please refer to the domestic hot water
tank installation manual.

■ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.

■ The installation location is frost-free.

■ Be sure that sufficient precautions are taken, in accordance with

the applicable legislation, in case of refrigerant leakage.

■ When installing the unit in a small room, take measures in order
to keep the refrigerant concentration from exceeding allowable
safety limits in the event of a refrigerant leak.

Excessive refrigerant concentrations in a closed room can
lead to oxygen deficiency.

■ Do not climb, sit or stand on top of the unit.

■ Do not place any objects or equipment on top of the unit (top

plate).

■ Do not install the unit in places often used as workplace. In case
of construction works, where a lot of dust is created, the unit
must be covered.

■ Do not install the unit in places with high humidity (e.g.
bathroom) (max humidity (RH)=85%).
