never hold the connections in the direction of your body.
Residual coolant could escape.
● Components and spare parts must at least satisfy the
technical requirements defined by the manufacturer.
1.5.4 Site of installation
For safe and fault-free operation, it is necessary that the installation location of the Daikin Altherma EHS(X/H) fulfils certain criteria. Related information can be found in chapter 3.2.
Information on the installation site of other components can be
found in the associated documentation supplied with them.
1.5.5 Heating system and sanitary connection
● Create a heating system according to the safety requirements
12828.
of EN
● With sanitary connection, you must observe;
–EN 1717 - Protection of domestic water from contamina-
tion in domestic water installations and general requirements concerning safety equipment for the prevention of
domestic water contamination by back-flow
–EN 806 - Technical regulations for domestic water instal-
lations (TRWI)
– And, in addition, the country-specific legal regulations
1.5.7 Operation
The Daikin Altherma EHS(X/H):
● Do not operate until all installation and connection work is
completed.
● Only operate with a completely full storage tank (Level
indicator) and heating circuit.
● Operate at a maximum pressure of 3 bar.
● Only connect with a pressure reducer on the external water
supply (supply line).
● Only operate the with the specified quantity of coolant and the
type of coolant specified.
● Only operate if the protective cover is installed.
The specified servicing intervals should be adhered to and inspection work must be carried out.
1.5.8 Instructing the user/owner
● Before you hand over the Daikin Altherma EHS(X/H), explain
to the user/owner how to operate and check the system.
● Hand over the technical documentation (this document and
all supporting documents) to the user and advise him that
these documents must be made available at all times and be
stored in the immediate vicinity of the unit.
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.
If the Daikin Altherma EHS(X/H) 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
1.5.6 Requirements for the heating 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): ≤
– Conductivity: ≤ 2700 μS/cm
– Chloride: ≤ 250 mg/l
– Sulphate: ≤ 250 mg/l
– pH value (heating water): 6,5 - 8,5
3 mmol/l
Using 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.

3.3 Water connection
CAUTION:
If the Daikin Altherma EHS(X/H) 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.
● Flush the feed pipes before filling the heat
exchanger.
● Rinse out the heat distribution network (in the
existing heating system).
● Install the dirt filter or sludge separator into the
heating return flow (see chapter
CAUTION:
If the Daikin Altherma EHS(X/H) is connected to a cold
water line, where steel pipes are used, chips can
enter the special steel corrugated pipe heat exchanger
and remain there. This can lead to contact corrosion
damage and subsequently to leakage.
● Flush the feed pipes before filling the heat
exchanger.
● Install contamination filter in the cold water feed
(see chapter

ONLY DAIKIN ALTHERMA EHS(X/H)B
CAUTION:
If the heat exchanger for charging the pressurised
solar system (figure 3-1/figure 3-2, item 8+9) has an
external heating unit (e.g. wood-burning boiler) con-
nected to it, an excessive flow temperature at these
connections can damage or destroy the Daikin Altherma EHS(X/H)B.
● The feed flow temperature of the external heater
should be limited to max. 95
°C.
In accordance with EN 12828 you must install a safety
valve at or in the immediate vicinity of the heat
exchanger, with which you can limit the maximum per
missible operating pressure in the heating system..
There should be no hydraulic blocking elements
between the heat generator and the safety valve.
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.
A diaphragm expansion vessel of adequate dimensions
and pre-set for the heating system must be connected
to the Daikin Altherma EHS(X/H). There should be no
hydraulic blocking elements between the heat genera
tor and the diaphragm expansion vessel.
Daikin recommends integrating a mechanical manometer for the filling of the heating system.

3.4.11 Connection of external temperature sensor RoCon OT1
The exterior heat pump unit of the Daikin Altherma EHS(X/H) has
a built-in exterior temperature sensor which is used to regulate
the inflow temperature depending on the weather, with frost pro
tection function.
Instead of the exterior temperature sensor built into the exterior
heat pump unit, the optional exterior temperature sensor RoCon
OT1 can also be used to regulate the inflow temperature de
pending on the weather, with frost protection function.
If the Daikin Altherma EHS(X/H) is used in a CAN bus
system as a master ("terminal function" for the remote
control of other data bus devices), the exterior temper
ature sensor RoCon OT1 must be connected directly
to the regulator RoCon HP on the master and not to
the remote controlled device (mixer circuit module
