2 x Safety
Information on the installation site of other components can be found in the associated documentation supplied with them.
2.4.5 Sanitary connection
● You must comply with:
– EN 1717 - Protection of domestic water
from contamination in domestic water
installations and general requirements concerning safety equipment for the prevention
of domestic water contamination by backflow
– EN 806 - Technical regulations for domestic water installations (TRWI)
– and, as a supplement, the country-specific
legal requirements.
A safety valve must be fitted in the domestic
water feed to the DAIKIN EKHHP. There should
be no isolating fitting between the safety valve
and the DAIKIN EKHHP.
Any steam or heating water which may escape
must be diverted by a suitable blow-off line with
constant gradient in a frost-protected, safe and
observable manner.
The storage tank temperature can exceed 60 °C
if you connect a solar system.
● For this reason you should fit scalding
protection (e.g. VTA32 + Verschraubungsset
1") during installation.
The domestic water quality must comply
with the EU Guideline 98/83 EC and the
regionaly-applicable regulations.
2.4.6 Requirements for the depressurised

– with a suitable device for the safe draining
or catching of escaping water,
– wearing appropriate protective clothing.
Alternatively, you can use the optional KFE filling
connection (KFE BA).
6.1 Temporary shutdown
CAUTION!
A shutdown hot water heat pump can freeze in
the event of frost and may suffer damage as a
result.
● Drain the water out of the shutdown hot water

If the DAIKIN EKHHP is not needed for a long time, it can be temporarily decommissioned.
However, DAIKIN recommends not disconnecting the system
from the power supply, but just switching it off (actuate button
).
The system is then protected from frost.
If it is not possible to guarantee the power supply when there is
danger of frost,
– the DAIKIN EKHHP must be fully drained of water.
If there is a danger of frost and the power supply cannot
be guaranteed for just a few days, the unit's excellent
heat insulation means that the DAIKIN EKHHP does
not have to be drained, provided that the storage tank
temperature is monitored regularly and does not fall
below +3 °C.
However, this does not provide frost protection for the connected heat distribution system.
Fig. 6-2
Unscrew threaded piece
● Place a suitable collection trough beneath the filling and
emptying fitting.
● Unscrew the threaded piece (Fig. 6-3, Item E) at the filling

6.1.2 Draining the hot water circuit
● Close the cold water supply to the DAIKIN EKHHP.
● Separate the cold water supply pipe to the DAIKIN EKHHP
and allow the hot water distribution network to empty out.
● Isolate the cold water supply and hot water outlet from the
DAIKIN EKHHP.
● Connect the drain hoses to cold water supply and hot water
outlet so that the end of the hose is located just above ground
level.
● Allow heat exchanger to drain according to the siphon
principle.
At normal atmospheric pressure and ambient
temperatures, liquid coolant vapourises so
suddenly that on contact with skin or eyes it
can cause the tissue to freeze (danger of going
blind).
● Work on the DAIKIN EKHHP (such as
dismantling components, temporary or final
shutdown of system) is only to be carried out
by persons who are authorised and who have
successfully completed qualifying technical
or vocational training for the specific
activity and who have taken part in advanced
training sessions recognised by the relevant
responsible authorities. These include, in
particular, certified heating engineers,
qualified electricians and HVAC
specialists, who on account of their professional training and expert knowledge,
have experience in the professional installation and maintenance of heating, cooling
and air conditioning systems and heat
pumps.
● You must observe the warning and safety
instructions in the installation manual on
working in the coolant system.
A final shutdown may be necessary if
– the system is defective and is being dismantled and disposed
of.
– components of the system are defective, are being dismantled and replaced.
– the system or parts of the system are being dismantled and
reassembled in another location.
The DAIKIN EKHHP is designed to be environmentally friendly

7.3.1 ECO
In order to increase the efficiency, we try not to use the integrated
electric Booster-Heater (BSH) in this operating mode (simultaneous operation of hot water heat pump and Booster-Heater
(BSH) is not permitted, other than with activated 'Low-Noise Operation").
In addition, most individual settings can be made in order to guarantee convenient and efficient operation. The settings are carried
out using the parameters, as described in Chapter 5.6.
If the installation is switched on, it regulates the hot water generation fully-automatically, based on the stipulations set in the controller.

7.3.3 Low Noise
Low noise mode means that the exterior heat pump unit is operating at reduced output. This reduces the operating noise caused
by the exterior heat pump unit.
The operating mode "Low noise operation" reduces the

keys to set the desired
The hot water set temperature should be selected so
that, in combination with the setting for the hysteresis
(parameter [6-00]), the tank storage of the DAIKIN
EKHHP is not cooled excessively before hot water
generation.
The hot water generation can be affected by additional functions:
– Low-noise operation
– Switching times programming
– Automatic defrosting function
– Thermal disinfection (Legionella protection)
– HT/NT Function
– Smart Grid Function
If the user enters a value manually, this setting remains active
until the user changes it or until set special functions affect it. At
the end of the special function, we again use the set value.
Setting the switching times for the hot water generation is described in Chapter 7.4.
If the set temperature value for hot water generation is not
achieved by the heat pump external unit, the controller switches
over to the integrated Booster-Heater (BSH).
The Booster-Heater (BSH) is only switched on if the hot water
temperature has been set above the maximum temperature
value achievable by the heat pump (THP MAX) and the value
measured by the temperature sensor has reached the temperature (THP Max).
7.3.2 AUTOMATIC
This operating mode is similar to the operating mode "ECO", but,
after 60 minutes, the integrated electric Booster-Heater (BSH) is
automatically added in for heating and other settings are carried

of the programmed switching times and keeping this in a safe
place.
The user can carry out manual setting changes even if the timer
programme is switched on. The controller always only works according to the most recent user parameters set until new parameters are set. In this way, manually executed settings are cancelled by the timer programme at the next active switch time.
The integrated Booster-Heater (BSH) is also controlled fully-automatically by the controller integrated in the DAIKIN EKHHP.
The switching limits and switching time periods are defined in the
parameter settings. If the Booster-Heater (BSH) is added in, the
controller dispaly shows the symbol

Tab. 7-3 Configuration table parameter [7-00]
Explanations of behaviour of the heat pump as per Tab. 7-3:
Normal operating mode: Heat pump operating works in the set
operating mode, as described in Section 7.3.
Reduced mode: Heat pump works only in heat retention function
with a fixed target value of 40 °C. The Booster-Heater (BSH) is
never added in parallel. This function is also carried out if the parameter [0-04] = 0 is set.
Switch-on recommendation: Heat pump works with increased
set value and reduced switch-on hysteresis. The Booster-Heater
(BSH) is added in after 60 minutes at the earliest in accordance
with the settings of parameter [4-03].
Switch-on command: The heat pump works in high-performance mode with a greatly increased set value. The BoosterHeater (BSH) is always added in immediately.
[7-01] - Switching hysteresis Booster-Heater (BSH)
If the hot water set temperature is set to a value which is above
the maximum hot water temperature achieved in exclusively heat
pump mode, the electrical Booster-Heater (BSH) is switched on
for hot water generation (see Fig. 7-6).

[7-02] - Emergency operation
The parameter [7-02] is set to "0" in the factory. If there is a fault
in the heat pump external unit, the parameter [7-02] =1 can be
set. In addition, the unit must be set to the operating mode "Automatic".
This is used for the hot water generation if the error is detected
just by the electric Booster-Heater (BSH).
Inform the DAIKIN Service Expert.
Please use this function only in the event of a fault and
you should always reset as soon as the repairs have
been carried out, since otherwise elevated costs will be incurred.
The electric Booster-Heater (BSH) is activated if a fault in the
heat pump external unit has occurred and has been detected for
longer than 1 hour.
[7-04] - Minimum ambient temperature
This parameter defines the minimum external temperature at
which the heat pump is still operated.
[E] - Display unit information
These parameters allow the display of various different unit information in the heat pump inside unit DAIKIN EKHHP.
No settings can be made for this parameter.

9.1 General
The European statutory investigation period applies for
heat pumps from a total system coolant filling quantity
of 3 kg or, as of 01.01.2017 from a total filling quantity
of 5 t CO2-equivalent (in the case of R410A from
2.4 kg).
Regular inspection and maintenance of the DAIKIN EKHHP reduces energy consumption and ensures a long life and smooth
operation.
RISK OF ENVIRONMENTAL
DAMAGE!
Important information regarding the coolant
used.
The complete heat pump system contains refrigerant with fluorinated greenhouse gases
which damage the environment if released.
Coolant type: R410A
GWP* value: 2087,5
* GWP = Global Warming Potential
● Work on fixed cooling systems (heat pumps)
and air-conditioning systems can only be
performed by persons who hold a certificate
of competence for the European Region, in
accordance with the F-Gas Regulation (Ec)
No. 303/2008.
● Fill in the total coolant filling quantity on the
supplied lable on the heat pump exterior unit
(for information consult the installation
instructions for the heat pump exterior unit).
● Never allow coolant to be released into the
atmosphere - always suction it off and recycle
using a suitable recycling device.
Have the inspection and maintenance carried out by
authorised and trained HVAC engineers once a year,
ideally before the heating period. This can prevent
faults during the heating period.
.DAIKIN recommends an inspection and maintenance contract
to ensure regular inspection and maintenance.
Legal requirements
In accordance with the F-Gases Directive (EU) No. 517/2014 Article 3 and 4, operators (owners) must service their fixed refrigeration units, check them for leaks and rectify any leaks without
delay.
All installation, maintenance and repair work on the cooling circuit
must be documented e.g. in the operating manual.
DAIKIN nonetheless recommends the conclusion of a maintenance contract, including documentation of the work carried out
in the operating manual in order to preserve the right to guarantee, including for systems for which there is not legal obligation
to monitor impermeability.
● With a system coolant total filling quantity of 3 kg – 30 kg
or from 6 kg in hermetic systems and from 01.01.2017 with a
total filling quantity of 5-50 t CO2-equivalent or from 10 t CO2equivalent in hermetic systems:
 Inspections carried out by certified personnel at intervals
of no more than 12 months and documentation of the
work performed in accordance with valid regulations. This
documentation must be retained for at least 5 years.
Certified people are those who have proof of expertise
for the European Community for work on stationary
refrigeration systems (heat pumps) and air conditioning
systems, according to the F-Gases Directive (EC)
303/2008.

up to 3 kg coolant fill quantity: Expert certificate category II
3 kg coolant fill quantity or over: Expert certificate category I
9.2 Periodic Checks
Depending on the design, a part of the depressurised storage
tank water can evaporate over a certain period of time. This
process does not represent a technical fault, but is rather a
physical property which requires periodic checking and correction, if necessary, by the operator.
● Remove the protective cover (see Section 4.4).
● Visual check of the water storage tank level (filling level
indicator)
 Top up the water if necessary (see Section 9.2.1 and
9.2.2, and determine the cause for the incorrect filling
level and rectify.
CAUTION!
Filling the storage tank container with excessive
water pressure or with too high a flow speed can
cause damage to the DAIKIN EKHHP.
● Only fill with a water pressure <6 bar and a
flow speed <15 l/min.
Operators of DAIKIN heat pump systems are subject to the
