result in serious physical injuries or death, as
well as property damage.
To prevent such risks, install and operate Daikin
EKHWP / EKHWC / EKHWD only:
– as stipulated and in perfect condition,
– with an awareness of safety and the hazards
involved.
This assumes knowledge and use of the contents of this manual, of the relevant accident prevention regulations as well as the recognised
safety-related and occupational health rules.

WARNING!
This unit is not intended for use by persons (including children) with impaired physical,
sensory or mental faculties or persons with insufficient experience and/or expertise unless
supervised by a person responsible for ensuring
their safety or are given instruction by this
person on how to use the unit.
● Keep flammable materials away from the
Daikin EKHWP / EKHWC / EKHWD.

2 x Safety
2.3 Use as intended
The Daikin EKHWP / EKHWC / EKHWD may
only be used as a hot water storage tank. The
Daikin EKHWP / EKHWC / EKHWD must be installed, connected and operated only according
to the information in this manual.
When connecting to a Daikin heat pump you
must use only the storage tank connection kits
(E-PAC) provided for the purpose.
Only those electric immersion heaters supplied
by Daikin may be used.
Any other use outside the intended use is considered as improper. The operator alone shall
bear responsibility for any resulting damage.
Intended use also includes compliance with the
maintenance and service conditions. Replacement parts must at least satisfy the technical requirements defined by the manufacturer.
This is the case, for example, with the use of
original replacement parts.
2.4 Instructions for operating safety
2.4.1 Before working on the hot water storage tank and the heating system
2.4.2 Electrical installation of optional accessories
● Before beginning work on live parts,
disconnect them from the power supply
(switch off main switch, remove fuse) and
secure against unintentional restart.
● Electrical installations may only be carried out
by qualified electrical technicians under
observance of the relevant electrical guidelines and the regulations of the electric utilities
company.
● For each hard wired power connection, install
a separate disconnector system compliant
with EN 60335-1 for all-pole disconnection
from the power mains.
● Compare the mains voltage indicated on the
nameplate with the supply voltage before
connecting to the mains.
2.4.3 Housing installation room
For safe and fault-free operation, it is necessary
that the installation location of the Daikin
EKHWP / EKHWC / EKHWD fulfils certain criteria. Information on the installation location for
the high-performance hot water storage tank can
be found in chapter 4.2 "Installation".
● Work on the hot water storage tank and
heating system (e.g. installation, connection
and initial start-up) should only be carried out
by authorised and trained heating experts.
● Switch off the main switch before starting any
work on the domestic hot water storage tank
and heating system and secure it against
unintentional switch-on.
● Seals must not be damaged or removed.
● Make sure that the safety valves comply with
the requirements of EN 12828 when
connecting on the heating side, and with the
requirements of EN 12897 when connecting
on the domestic water side.
● Only original Daikin replacement parts may be
used.
Information on the installation site of other components can be found in the associated documentation supplied with them.
2.4.4 Requirements of the heating and filling water
Observe the current technological regulations to
prevent corrosion products and deposits.
Minimum requirements regarding the quality
of filling and supplementary water:
– Water hardness (calcium and magnesium,
calculated as calcium carbonate):
≤ 3 mmol/l
– Conductivity: ≤ 1500 (ideal ≤ 100) μS/cm
– Chloride: ≤ 250 mg/l
– Sulphate: ≤ 250 mg/l
– pH value (heating water): 6.5 - 8.5
Use of filling water and top-up water which does
not meet the stated quality requirements can
cause a considerably reduced service life of the
equipment. The responsibility for this lies solely
with the operator.

2 x Safety
2.4.5 Heating and sanitary side connection
● Create a heating system according to the
safety requirements of EN 12828.
● With a sanitary connection you must comply
with
–EN 1717 – Protection against pollution of
potable water installations and general
requirements of devices to prevent pollution by backflow
–EN 806 – Specifications for installations
inside buildings conveying water for human
consumption
– and, in addition, the country-specific legal
stipulations.
The domestic water quality must comply
with the EU Guideline 98/83 EC and the
regional applicable regulations.
The connection of a solar installation, an electric
heating rod or an alternative heat generator may
cause the storage temperature to exceed 60 °C.
● For this reason you should fit scalding
protection (e.g. VTA32 + Screw connection
set 1") during installation.
● Use a pressure reducer if the cold water
connection
pressure >6 bar.
If the Daikin EKHWP / EKHWC / EKHWD is
connected to a heating system with steel pipes,
radiators or non-diffusion-proof floor heating
pipes, slurry and swarf could enter the hot water
storage tank and cause blockages, local
overheating or corrosion.
● To prevent possible damage, fit a dirt filter or
sludge separator into the heating return flow
of the system.
–SAS 1
2.4.6 Operation
● Only operate the Daikin EKHWP / EKHWC /
EKHWD:
– After all installation and connection work
has been completed.
– With fully installed equipment covers and
service accesses.
– With sanitary side pressure reducers
installed (max. 6 bar).
– With heating side pressure reducers
installed (max. 3 bar).
– With completely filled storage containers
(fill level display).
The prescribed maintenance intervals must be
maintained and the inspection work must be
carried out.
2.4.7 Instruct the owner
● Before you hand over the heating system and
the hot water storage tank, explain to the
owner how he/she can operate and check the
heating system.
● Provide the operator with the technical
documentation (this documentation and all its
references) and indicate that these
documents must be available in the
immediate vicinity of the unit at all times.
● Document the hand-over by filling in and
signing the checklist in chapter 5 "Start-up",
together with the operator.
2.4.8 Documentation
The technical documentation contained in the
scope of supply is part of the device. It must be
stored in such a way that it can be consulted at
any time by the operator or the technicians.
