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.

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

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.

6.DESIGN OF THE WATER CIRCUIT

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	■ 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).

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.

Daikin Altherma indoor unit	11
4PW61263-1A – 10.2010

NOTE	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 T types (pump rpm=4000 for T=5°C;
	pump rpm=3600 for T=10°C). The pump of the
	indoor module is inverter controlled and controls
	to have a fixed T 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.

4High external static pressure system

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

12	Daikin Altherma indoor unit
	4PW61263-1A – 10.2010

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.

6.5.Selection of meters for billing purpose

Daikin advises an allocation method based on the measurements of consumed heat of each indoor unit. Following measurements are required:

■the outdoor unit power consumption: by means of an electrical power meter

■the indoor unit energy consumption:

■EKHVMYD by means of a heat and cooling meter

■EKHVMRD by means of a heat meter

■the indoor unit energy consumption during domestic hot water operation (if installed): by means of a heat meter.

The selection of the meters for billing purpose is the choice of the end customer.

Refer to databook for specifications to be used for meter selection.

WARNING

Selection and installation of the meters should be done in accordance with applicable legislation.

Check the meter supplier documentation for detailed installation instructions. Before installation of the meters, check the following points:

■install separate watt-hour meter for each outdoor unit

■all heat meters in the apartment are to be supplied by the same supplier

■to facilitate readout and service work, heat meters should be easily accessible. Choose a mounting location with sufficient clearance for data read-out.

■avoid installation of meters inside the indoor unit service space in order to guarantee indoor unit servicing.

■all heat meters and heating and cooling meters in the apartment building are to be installed at identical piping distance from the indoor unit.

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 10 m installations with domestic hot water tank).

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%).
