1 General safety precautions
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump
down the system, and there is a leak in the refrigerant
circuit:
▪ Do NOT use the unit's automatic pump down function,
with which you can collect all refrigerant from the
system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.
▪ Use a separate recovery system so that the unit's
compressor does NOT have to operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
▪ When the refrigerant system is to be opened,
refrigerant MUST be treated according to the applicable
legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant
may only be charged after performing the leak test and the
vacuum drying.
▪ In case recharge is required, see the nameplate of the unit. It
states the type of refrigerant and necessary amount.
▪ The unit is factory charged with refrigerant and depending on pipe
sizes and pipe lengths some systems require additional charging
of refrigerant.
▪ Only use tools exclusively for the refrigerant type used in the
system, this to ensure pressure resistance and prevent foreign
materials from entering into the system.
▪ Charge the liquid refrigerant as follows:
If Then
A siphon tube is present
(i.e., the cylinder is marked with
"Liquid filling siphon attached")
A siphon tube is NOT present Charge with the cylinder upside
Charge with the cylinder upright.
down.
CAUTION
When the refrigerant charging procedure is done or when
pausing, close the valve of the refrigerant tank
immediately. If the valve is NOT closed immediately,
remaining pressure might charge additional refrigerant.
Possible consequence: Incorrect refrigerant amount.
1.2.4 Brine
If applicable. See the installation manual or installer reference guide
of your application for more information.
WARNING
The selection of the brine MUST be in accordance with the
applicable legislation.
WARNING
Take sufficient precautions in case of brine leakage. If
brine leaks, ventilate the area immediately and contact
your local dealer.
WARNING
The ambient temperature inside the unit can get much
higher than that of the room, e.g. 70°C. In case of a brine
leak, hot parts inside the unit can create a hazardous
situation.
WARNING
The use and installation of the application MUST comply
with the safety and environmental precautions specified in
the applicable legislation.
1.2.5 Water

2 About the documentation
WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable
legislation.
▪ All field wiring MUST be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do NOT come in contact with the piping and sharp
edges. Make sure no external pressure is applied to the
terminal connections.
▪ Make sure to install earth wiring. Do NOT earth the unit
to a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
▪ Make sure to use a dedicated power circuit. NEVER
use a power supply shared by another appliance.
▪ Make sure to install the required fuses or circuit
breakers.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electric shock or fire.
▪ When installing the earth leakage protector, make sure
it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
CAUTION
When connecting the power supply, the earth connection
must be made before the current-carrying connections are
established. When disconnecting the power supply, the
current-carrying connections must be separated before the
earth connection is. The length of the conductors between
the power supply stress relief and the terminal block itself
must be as such that the current-carrying wires are
tautened before the earth wire is in case the power supply
is pulled loose from the stress relief.
NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
▪ When connecting wiring which is the same thickness,
do as shown in the figure above.
▪ For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure being
exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.
▪ Over-tightening the terminal screws may break them.
WARNING
▪ After finishing the electrical work, confirm that each
electrical component and terminal inside the electrical
components box is connected securely.
▪ Make sure all covers are closed before starting up the
unit.
NOTICE
Only applicable if the power supply is three‑phase, and the
compressor has an ON/OFF starting method.
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.

5 Application guidelines
5.1 Overview: Application guidelines
The purpose of the application guidelines is to give a glance of the
possibilities of the heatpump system.
NOTICE
▪ The illustrations in the application guidelines are meant
for reference only, and are NOT to be used as detailed
hydraulic diagrams. The detailed hydraulic
dimensioning and balancing are NOT shown, and are
the responsibility of the installer.
▪ For more information about the configuration settings to
optimize heat pump operation, see
"10Configuration"[457].
This chapter contains application guidelines for:
▪ Setting up the space heating/cooling system
▪ Setting up an auxiliary heat source for space heating
▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up the power consumption control
▪ Setting up an external temperature sensor
▪ Setting up passive cooling
▪ Setting up the brine low pressure switch
5.2 Setting up the space heating/ cooling system
The heatpump system supplies leaving water to heat emitters in one
or more rooms.
Because the system offers a wide flexibility to control the
temperature in each room, you need to answer the following
questions first:
▪ How many rooms are heated or cooled by the heatpump system?

Once the space heating/cooling requirements are clear, we
recommend to follow the setup guidelines below.
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if [C.2] Space
heating/cooling=On.
INFORMATION
In case an external room thermostat is used and room frost
protection needs to be guaranteed in all conditions, then
you have to set Emergency [9.5] to Automatic.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown

5.2.2 Multiple rooms – OneLWT zone
If only one leaving water temperature zone is needed because the
design leaving water temperature of all heat emitters is the same,
you do NOT need a mixing valve station (cost effective).
Example: If the heat pump system is used to heat up one floor
where all the rooms have the same heat emitters.
Underfloor heating or radiators – Thermostatic valves
If you are heating up rooms with underfloor heating or radiators, a
very common way is to control the temperature of the main room by
using a thermostat (this can either be the dedicated Human Comfort
Interface (BRC1HHDA) or an external room thermostat), while the
other rooms are controlled by so-called thermostatic valves, which
open or close depending on the room temperature.
INFORMATION
Mind situations where the main room can be heated by
another heating source. Example: Fireplaces.

5.2.3 Multiple rooms – TwoLWT zones
If the heat emitters selected for each room are designed for different
leaving water temperatures, you can use different leaving water
temperature zones (maximum 2).
In this document:
▪ Main zone = Zone with the lowest design temperature in heating,
and the highest design temperature in cooling
▪ Additional zone = Zone with the highest design temperature in
heating, and the lowest design temperature in cooling
CAUTION
If there is more than one leaving water zone, ALWAYS
install a mixing valve station in the main zone to decrease
(in heating) the leaving water temperature when the
additional zone has demand.
Typical example:
Room (zone) Heat emitters: Design
temperature
Living room (main zone) Underfloor heating:
▪ In heating: 35°C
▪ In cooling: 20°C (only
refreshment, no real cooling
allowed)
Bed rooms (additional zone) Heatpump convectors:
▪ In heating: 45°C
▪ In cooling: 12°C

Benefits
▪ Comfort.
▪ The smart room thermostat functionality can decrease or
increase the desired leaving water temperature based on the
actual room temperature (modulation).
▪ The combination of the two heat emitter systems provides the
excellent heating comfort of the underfloor heating, and the
excellent cooling comfort of the heatpump convectors.
▪ Efficiency.
▪ Depending on the demand, the indoor unit supplies different
leaving water temperature matching the design temperature of
the different heat emitters.
▪ Underfloor heating has the best performance with the heat
pump system.
5.3 Setting up an auxiliary heat source for space heating
▪ Space heating can be done by:
▪ The indoor unit
▪ An auxiliary boiler (field supply) connected to the system
▪ When the room thermostat requests heating, the indoor unit or the
auxiliary boiler starts operating depending on the outdoor
temperature (status of the changeover to external heat source).
When the permission is given to the auxiliary boiler, the space
heating by the indoor unit is turned OFF.
▪ Bivalent operation is only possible for space heating, NOT for
domestic hot water production. Domestic hot water is always
produced by the DHW tank connected to the indoor unit.
INFORMATION
▪ During heating operation of the heat pump, the
heat pump operates to achieve the desired
temperature set via the user interface. When weatherdependent operation is active, the water temperature is
determined automatically depending on the outdoor
temperature.
▪ During heating operation of the auxiliary boiler, the
auxiliary boiler operates to achieve the desired water
temperature set via the auxiliary boiler controller.
Setup
▪ Integrate the auxiliary boiler as follows:
A Main leaving water temperature zone
B One single room
a Dedicated Human Comfort Interface (BRC1HHDA used as
room thermostat)
b Remote outdoor sensor
c Non-return valve (field supply)

A Domestic hot water
a Cold water IN
b Hot water OUT
c Remote outdoor sensor
5.4.2 Selecting the volume and desired temperature for the DHW tank
People experience water as hot when its temperature is 40°C.
Therefore, the DHW consumption is always expressed as equivalent
hot water volume at 40°C. However, you can set the DHW tank
temperature at a higher temperature (example: 53°C), which is then
mixed with cold water (example: 15°C).
Selecting the desired temperature for the DHW tank consists of:
1 Determining the DHW consumption (equivalent hot water
volume at 40°C).
2 Determining the desired temperature for the DHW tank.
Determining the DHW consumption
Answer the following questions and calculate the DHW consumption
(equivalent hot water volume at 40°C) using typical water volumes:
Question Typical water volume
How many showers are needed
per day?
How many baths are needed per
day?
How much water is needed at the
kitchen sink per day?
Are there any other domestic hot
water needs?
1shower = 10min×10l/min =
100l
1bath = 150l
1sink = 2min×5l/min = 10l

Example: If the DHW consumption of a family (4 persons) per day
is as follows:
▪ 3 showers
▪ 1 bath
▪ 3 sink volumes
Then the DHW consumption = (3×100l)+(1×150l)+(3×10l)=480l
Determining the desired temperature for the DHW tank
Formula Example
V1=V2+V2×(T2−40)/(40−T1) If:
▪ V2=180l
▪ T2=54°C
▪ T1=15°C
Then V1=280l

INFORMATION
DHW tank volume. You cannot select the volume of the
DHW tank because only one size is available.
Energy saving tips
▪ If the DHW consumption differs from day to day, you can program
a weekly schedule with different desired DHW tank temperatures
for each day.
▪ The lower the desired DHW tank temperature, the more cost
effective.
▪ The heatpump itself can produce domestic hot water of maximum
55°C. The electrical resistance (backup heater) integrated in the
heat pump can increase this temperature. However, this
consumes more energy. We recommend to set the desired DHW
tank temperature below 55°C to avoid using the electrical
resistance.
▪ When the heatpump produces domestic hot water, it cannot heat
up a space. In case you need domestic hot water and space
heating at the same, we recommend to produce the domestic hot
water during the night when there is lower space heating demand.
5.4.3 Setup and configuration – DHW tank
▪ For large DHW consumptions, you can heat up the DHW tank
several times during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature,
you can use the following energy sources:
▪ Thermodynamic cycle of the heatpump
▪ Electrical backup heater
▪ For more information about optimizing the energy consumption for
producing domestic hot water, see "10Configuration"[457].
5.4.4 DHW pump for instant hot water

responsibility of the installer. For the electrical wiring, see
"8.2.5To connect the domestic hot water pump"[440].
Configuration
▪ For more information, see "10Configuration"[457].
▪ You can program a schedule to control the DHW pump via the
user interface. For more information, see the user reference
guide.

▪ The DHW pump is field-supplied and its installation is the
responsibility of the installer. For the electrical wiring, see
"8.2.5To connect the domestic hot water pump"[440].
▪ If the applicable legislation requires a higher temperature than the
maximum tank setpoint during disinfection (see [2-03] in the field
settings table), you can connect a DHW pump and heater element
as shown above.
▪ If applicable legislation requires disinfection of the water piping
until the tapping point, you can connect a DHW pump and heater
element (if needed) as shown above.
Configuration
The indoor unit can control DHW pump operation. For more
information, see "10Configuration"[457].

5.5 Setting up the energy metering
▪ Via the user interface, you can read out the following energy data:
▪ Produced heat
▪ Consumed energy
▪ You can read out the energy data:
▪ For space heating
▪ For space cooling
▪ For domestic hot water production
▪ You can read out the energy data:
▪ Per month
▪ Per year
INFORMATION
The calculated produced heat and consumed energy are
an estimation, the accuracy cannot be guaranteed.
5.5.1 Produced heat
INFORMATION
The sensors used to calculate the produced heat are
calibrated automatically.
▪ The produced heat is calculated internally based on:
▪ The leaving and entering water temperature
▪ The flow rate
▪ Setup and configuration: No additional equipment needed.
5.5.2 Consumed energy
You can use the following methods to determine the consumed
energy:
▪ Calculating
▪ Measuring
Power supply layouts with power meters
In most cases, one power meter that measures the entire system
(compressor, backup heater and hydro) is sufficient.
Power meter Measures Type Connection
1 Entire system 1N~ or 3N~

is added so you do NOT have to set which meter covers
which power consumption.
Exceptional cases. You can also use a second power meter if:
▪ The power range of one meter is insufficient.
▪ The power meter cannot easily be installed in the electrical
cabinet.
▪ 230 V and 400 V three-phase grids are combined (very
uncommon), because of technical limitations of power meters.

X5M/5+6
X5M/5+6
INFORMATION
You cannot combine calculating the consumed energy
(example: for the backup heater) and measuring the
consumed energy (example: for the rest of the unit). If you
do so, the energy data will be invalid.
Calculating the consumed energy
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the indoor unit
▪ The set capacity of the backup heater
▪ The voltage
▪ Setup and configuration: None.
Measuring the consumed energy
▪ Preferred method because of higher accuracy.
▪ Requires external power meters.
▪ Setup and configuration: When using electrical power meters, set
the number of pulses/kWh for each power meter via the user
interface.
INFORMATION
When measuring the electrical power consumption, make
sure ALL power input of the system is covered by the
electrical power meters.

NOTICE
It is possible to install a field fuse with lower than
recommended rating over the heat pump. For this you
must modify field setting [2‑0E] according to the maximum
allowed current over the heat pump.
Note that field setting [2‑0E] overrules all power
consumption control settings. Power limiting the heat pump
will reduce performance.
5.6.1 Permanent power limitation
Permanent power limitation is useful to assure a maximum power or
current input of the system. In some countries, legislation limits the
maximum power consumption for space heating and DHW
production.

interface (see "Power consumption control"[483]):
▪ Select continuous limitation mode
▪ Select the type of limitation (power in kW or current in A)
▪ Set the desired power limitation level
5.6.2 Power limitation activated by digital inputs
Power limitation is also useful in combination with an energy
management system.
The power or current of the entire Daikin system is limited
dynamically by digital inputs (maximum four steps). Each power
limitation level is set via the user interface by limiting one of the
following:
▪ Current (in A)
▪ Power input (in kW)
The energy management system (field supply) decides the activation
of a certain power limitation level. Example: To limit the maximum
power of the entire house (lighting, domestic appliances, space
heating…).
Configuration
▪ Set the power consumption control settings in [9.9] via the user
interface (for the description of all settings, see "Power
consumption control"[483]):
▪ Select limitation by digital inputs.
▪ Select the type of limitation (power in kW or current in A).
▪ Set the desired power limitation level corresponding to each
digital input.
INFORMATION
In case more than 1 digital input is closed (at the same
time), the digital input priority is fixed: DI4 priority>…>DI1.
5.6.3 Power limitation process
The compressor has better efficiency than the electrical heater.
Therefore, the electrical heater is limited and turned OFF first. The
system limits power consumption in the following order:
1 Limits the backup heater.
2 Turns OFF the backup heater.
3 Limits the compressor.
4 Turns OFF the compressor.
Example
If the power limitation level does NOT allow operation of full backup
heater capacity, then power consumption is limited as follows:
A Indoor unit
B Energy management system
a Power limitation activation (4 digital inputs)
b Backup heater
PiPower input
t Time
DI Digital inputs (power limitation levels)
a Power limitation active
b Actual power input
Setup
▪ Demand PCB (option EKRP1AHTA) needed.
▪ Maximum four digital inputs are used to activate the
corresponding power limitation level:
▪ DI1 = weakest limitation (highest energy consumption)
▪ DI4 = strongest limitation (lowest energy consumption)
▪ For the specifications of the digital inputs, and for where to
connect them, refer to the wiring diagram.

5.6.4 Current limitation by current sensors
INFORMATION
Restriction: Current limitation by current sensors is only
available for 3-phase setups ([9.3.2]=2 (Installer
settings > Backup heater > Voltage = 400V, 3ph)).
NOTICE
Disconnected sensor. If you use current limitation by
current sensors and one of the sensors is disconnected,
the corresponding phase is not limited anymore.
Current sensors can be used to limit the consumption of the heat
pump on every phase taking into account the set household fuse
and the actual consumption of other appliances.
Current sensors must be installed before the main fuses on each
phase to make use of this feature. This function can be useful in
countries where the government gives incentives to limit the fuse
sizes.

5.7 Setting up an external temperature sensor
Indoor ambient temperature
You can connect one external temperature sensor. It can measure
the indoor ambient temperature. We recommend to use an external
temperature sensor in the following cases:
▪ In room thermostat control, the dedicated Human Comfort
Interface (BRC1HHDA) is used as room thermostat and it
measures the indoor ambient temperature. Therefore, the
dedicated Human Comfort Interface must be installed on a
location:
▪ Where the average temperature in the room can be detected
▪ That is NOT exposed to direct sunlight
▪ That is NOT near a heat source
▪ That is NOT affected by outside air or air draught because of,
for example, door opening/closing
▪ If this is NOT possible, we recommend to connect a remote indoor
sensor (option KRCS01-1).
▪ Setup and configuration:
See:
▪ Installation manual of the remote indoor sensor
▪ Addendum book for optional equipment
Wires: 2×0.75mm²

these settings.
Note: This is different from the permanent power limitation,
which is always changeable.
Use the BBR16 power limitation when you must comply with BBR16
regulations (Swedish energy regulations).
You can combine the BBR16 power limitation with the other power

5.9 Setting up the brine low pressure switch
Depending on the applicable legislation, you might have to install a
brine low pressure switch (field supply).
The brine low pressure switch can be used to notify the user when
there is a leak in the brine circuit. The switch (normally closed) is
triggered when the pressure in the brine circuit is lower than the
threshold value of the switch.
NOTICE

7.1.1 Circuit requirements
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
NOTICE
In case of plastic pipes, make sure they are fully oxygen
diffusion tight according to DIN 4726. The diffusion of
oxygen into the piping can lead to excessive corrosion.
▪ Circuit types. Except for the refrigerant circuit, inside the unit 2
other circuits are included. For future references: the circuit
connected to the bore hole is referred to as the brine circuit, the
other circuit connected to the heating emitters is referred to as the
space heating circuit.
▪ Connecting piping – Legislation. Make all piping connections in
accordance with the applicable legislation and the instructions in
the "Installation" chapter, respecting the water inlet and outlet.
▪ Connecting piping – Force. Do NOT use excessive force when
connecting the piping. Deformation of the piping can cause
malfunctioning of the unit.
▪ Connecting piping – Tools. Only use appropriate tooling to
handle brass, which is a soft material. If NOT, pipes will get
damaged.
▪ Connecting piping – Air, moisture, dust. If air, moisture or dust
gets into the circuit, problems may occur. To prevent this:
▪ Only use clean pipes
▪ Hold the pipe end downwards when removing burrs.
▪ Cover the pipe end when inserting it through a wall, to prevent
dust and/or particles from entering the pipe.
▪ Use a decent thread sealant to seal connections.
▪ Closed circuit. Use the indoor unit ONLY in a closed water
system for brine circuit and space heating circuit. Using the
system in an open water system will lead to excessive corrosion.
▪ Fluid pressure – Space heating and brine circuit. The
maximum fluid pressure of the space heating and brine circuit is
3bar.
▪ Fluid pressure – Domestic hot water tank. The maximum fluid
pressure of the domestic hot water tank is 10 bar. Provide
adequate safeguards in the water circuit to ensure that the
maximum pressure is NOT exceeded.
▪ Fluid temperature. All installed piping and piping accessories
(valve, connections,…) MUST withstand the following
temperatures:
INFORMATION
The following illustration is an example and might NOT
match your system layout.
WARNING
When connecting to an open groundwater system, an
intermediate heat exchanger is required to prevent
damage (dirt, freeze ups) to the unit.
▪ Expansion vessel – Water side. To avoid cavitation, install an
expansion vessel (field supply) on the entering pipe before the
water pump within 10m of the unit.
▪ Glycol. For safety reasons, it is NOT allowed to add any kind of
glycol to the space heating circuit.
▪ Piping length. It is recommended to avoid long runs of piping
between the domestic hot water tank and the hot water end point
(shower, bath,…) and to avoid dead ends.
▪ Piping diameter. Select the piping diameter in relation to the
required flow and the available external static pressure of the
pump. See "16 Technical data" [4 101] for the external static
pressure curves of the indoor unit.
▪ Fluid flow. Depending on the type of operation, the minimum
required flow can be different. See "7.1.3 To check the water
volume and flow rate of the space heating circuit and brine
circuit"[430] for more information.
▪ Field supply components – Fluid. Only use materials that are
compatible with fluid used in the system and with the materials
used in the indoor unit.
▪ Field supply components – Fluid pressure and temperature.
Check that all components in the field piping can withstand the
fluid pressure and fluid temperature.
▪ Drainage – Low points. Provide drain taps at all low points of the
system in order to allow complete drainage of the circuit.
▪ Drainage – Pressure relief valves. Provide a proper drain for the
pressure relief valves (of both the domestic hot water tank and the
domestic hot water tank kit) to avoid water spillage around the
unit. For the discharge piping connected to these valves, respect
the requirements from the table below. For more information, see
"7.3.4To connect the water piping for domestic hot water"[432].

▪ Drainage – Pressure relief valve (space heating/cooling
circuit). Connect the drain hose properly to the drain to avoid
water dripping out of the unit. See "6.3.4 To connect the drain
hose to the drain"[427].
▪ Zn-coated parts. NEVER use Zn-coated parts in the fluid circuit.
Because the unit's internal circuit uses copper piping, excessive
corrosion may occur. Zn-coated parts used in the brine circuit may
lead to the precipitation of certain components in the anti-freeze
fluids corrosion inhibitor.
WARNING
Due to the presence of glycol, corrosion of the system is
possible. Uninhibited glycol will turn acidic under the
influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic
uninhibited glycol attacks metal surfaces and forms
galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:
▪ the water treatment is correctly executed by a qualified
water specialist,
▪ a glycol with corrosion inhibitors is selected to
counteract acids formed by the oxidation of glycols,
▪ no automotive glycol is used because their corrosion
inhibitors have a limited lifetime and contain silicates
which can foul or plug the system,
▪ galvanized pipes are NOT used in glycol systems since
the presence may lead to the precipitation of certain
components in the glycol's corrosion inhibitor.
INFORMATION
Be aware of the hygroscopic property of anti-freeze fluids:
it absorbs moisture from its environment. Leaving the cap
off the anti-freeze fluid container causes the concentration
of water to increase. The anti-freeze fluid concentration is
then lower than assumed. And in consequence, freezing
can happen after all.
Preventive actions MUST be taken to ensure minimal
exposure of the anti-freeze fluid to air.
▪ Non-brass metallic piping. When using non-brass metallic
piping, insulate the brass and non-brass properly so that they do
NOT make contact with each other. This to prevent galvanic
corrosion.
▪ Valve – Change‑over time. When using a 2-way valve in the
space heating circuit, the maximum change-over time of the valve
MUST be 60seconds.
▪ Filter. It is strongly recommended to install an additional filter on
the heating water circuit. Especially to remove metallic particles
from foul heating piping, it is recommended to use a magnetic or
cyclone filter, which can remove small particles. Small particles
may damage the unit and will NOT be removed by the standard
filter of the heat pump system.
▪ Domestic hot water tank – Capacity. To avoid stagnation of
water, it is important that the storage capacity of the domestic hot
water tank meets the daily consumption of domestic hot water.
▪ Domestic hot water tank – After installation. Immediately after
installation, the domestic hot 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.
▪ Domestic hot water tank – Standstills. In cases where during
longer periods of time there is no consumption of hot water, the
equipment MUST be flushed with fresh water before usage.
▪ Domestic hot water tank – Disinfection. For the disinfection
function of the domestic hot water tank, see "10.5.6Tank"[475].
EGSAH/X06+10UDA9W
Daikin Altherma 3 GEO
4P598592-1 – 2019.10
▪ Domestic hot water tank kit – Clean pipes. Before installing the
domestic hot water tank kit, all piping and fittings must be flushed
free of flux and debris. Failure to do this may cause irreparable
damage to the tank kit control valves. Flush the system by
opening the hot water tap.
▪ Domestic hot water tank kit – Pressure balancing. To prevent
large pressure differences at the taps and damage to the shower
valve due to high‑pressure cold water (5bar), provide a dedicated
3.5‑bar feed to both cold water and hot water taps. To do this, also
connect the cold water supply for the cold water taps to the
pressure reducing valve of the domestic hot water tank kit.

▪ Domestic hot water tank – Pressure relief valve. A pressure
relief valve (part of the inlet control group) with an opening
pressure of 8bar prevents excessive water pressure in the water
circuit.
▪ Domestic hot water tank – Pressure and temperature relief
valve. The pressure and temperature relief valve prevents
excessive water pressure (≥10 bar) and excessive water
temperature (>95°C) in the domestic hot water tank.
▪ Thermostatic mixing valves. In accordance with the applicable
legislation, it may be necessary to install thermostatic mixing
valves.
▪ Hygienic measures. The installation must be in compliance with
the applicable legislation and may require additional hygienic
installation measures.
▪ Recirculation pump. In accordance with the applicable
legislation, it may be required to connect a recirculation pump in
between the hot water end point and the recirculation connection
of the domestic hot water tank.

7.1.3 To check the water volume and flow rate of the space heating circuit and brine circuit
The unit does not have an integrated expansion vessel, but a field
supplied expansion vessel can be installed in the brine circuit in case
installing the brine level vessel (delivered as accessory) is not
optimal. For more information, see "7.2.4To connect the brine level
vessel"[431].
To make sure that the unit operates properly:
▪ You must check the minimum water volume.
▪ You might need to adjust the pre-pressure of the expansion
vessel.
▪ You must check the total space heating water volume in the unit.
▪ You must check the total brine water volume in the unit.
Minimum water volume
Check that the total water volume per circuit in the installation is
minimum 20litre, the internal water volume of the indoor unit NOT
included.
INFORMATION
If a minimum heating load of 1kW can be guaranteed and
setting [4.B] Space heating/cooling > Overshoot
(overview field setting [9‑04]) is 4°C, the minimum water
volume can be lowered to 10litre.
INFORMATION
In critical processes, or in rooms with a high heat load,
extra water might be required.
NOTICE
When circulation in each space heating/cooling loop is
controlled by remotely controlled valves, it is important that
the minimum water volume is guaranteed, even if all of the
valves are closed.
7.1.4 Changing the pre-pressure of the expansion vessel
NOTICE
Only a licensed installer may adjust the pre-pressure of the
expansion vessel.
The expansion vessel is field supplied. For more information on how
to change the pre-pressure, see the manual of the expansion vessel.
Changing the pre-pressure of the expansion vessel should be done
by releasing or increasing nitrogen pressure through the Schrader
valve of the expansion vessel.
