1.5.3 Working on cooling systems (heat pump)
The Daikin Altherma EHS(X/H) requires fluorinated greenhouse
gas for its function.
For work on stationary refrigeration systems (heat
pumps) and air conditioning systems, proof of expertise
is required in the European Community according to
the F-Gases Directive (EC) No. 303/2008.
–up to 3 kg coolant fill quantity: Expert
certificate
category II
–3 kg coolant fill quantity or over: Expert certifi-
cate category I
● Always wear safety goggles and protective gloves.
● W
hen working on the refrigerant circuit, ensure that the
workplace is well ventilated.
● Never carry out work on the refrigerant circuit in closed rooms
or work pits.
● D
o not let coolant come into contact with open fire, embers or
hot objects.
● N
ever allow coolant to escape into the atmosphere (high
pressure at the point of the leak).
● When removing the service pipes from the filling connections,
never hold the connections in the direction of your body.
Residual refrigerant could escape.
● C
omponents 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 instal-
lation location of the Daikin Altherma EHS(X/H) fulfils certain cri-
teria. Related information ca
n be found in chapter 3.2.
Information on the installation site of other components can be
foun
d in the associated documentation supplied with them.
1.5.5 Heating system and sanitary connection
● Create a heating system according to the safety requirements
of EN 12828.
● W
ith sanitary connection, you must observe;
–EN 1717 - Protection of domestic water from contamina-
tion in domestic water installations and general require-
ments concerning safety equipment fo
r 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 leg
al regulations.
The connection of a solar installation, an ele
ctric heating rod or
an alternative heat generator may cause the storage temperature
to exceed 60 °C.
● F
or this reason you should fit scalding protection (e.g. VTA32
15 60 15 + Screw connection set 1" 15 60 16).
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.
● T
o prevent possible damage, fit a dirt filter or sludge
separator into the heating return flow of the system.
–SAS 1 (
15 60 21)
1.5.6 Requirements for the heating water
Observe the current technological regulations to prevent cor-
rosion products and deposits.
Minimum requirements regarding the quality of filling and sup-
plementary water:
– Water hardness (calcium and magnesium, calculated as
calcium car
bonate): ≤ 3 mmol/l
– Conductivity: ≤ 27
00 μS/cm
– Chloride: ≤ 250 mg/l
– Sulphate: ≤ 250 mg/l
– pH value (heating water): 6,5 - 8,5
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.
1.5.7 Operation
The Daikin Altherma EHS(X/H):
● Do not operate until all installation and connection work is
completed.
● On
ly operate with a completely full storage tank (Level
indicator) and heating circuit.
● Operate at a maximum pressure of 3 bar.
● On
ly 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.
● On
ly operate if the protective cover is installed.
The specified servicing intervals should be adhered to and in-
spection 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.
● Han
d 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.
● Make a record of
the handover by filling out and signing the
installation and instruction forms jointly with the user/owner.
