Service and maintenance
7.1 General
Regular inspection and maintenance of the Altherma EHS(X/H)
reduces energy consumption and ensures a long life and smooth
operation.
RISK OF ENVIRONMENTAL DAMAGE!
Important information regarding the coolant used.
The entire heat pump system contains coolant with
fluorinated greenhouse gases, which are listed in the
Kyoto Protocol and, if released, are harmful to the en-
vironment.
Coolant type: R410A
GWP* value: 1975
* 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.
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
According to the F-Gases Directive (EC) No. 842/2006 Article 3,
replaced on 01.01.2015 by (EC) No. 517/2014 Articles 3 and 4,
Operators (or Owners) must perform regular maintenance on
their fixed cooling systems, check impermeability and have any
leaks repaired immediately.
All installation, maintenance and repair work on the cooling circuit
must be documented e.g. in the operating manual.
Operators of Daikin heat pump systems are subject to the fol-
lowing obligations:
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 CO
-equivalent (in the case of R410A from
2
2.4 kg).
Daikin nonetheless recommends the conclusion of a
maintenance contract, including documentation of the
work carried out in the operating manual in order to pre-
serve the right to guarantee, including for systems for
which there is not legal obligation to monitor imperme-
ability.
● 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 CO
equivalent 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.

7.3 Activities to be performed annually
WARNING!
Improperly carried out work on the Daikin Altherma
EHS(X/H) and its components that have been con-
nected as an option can endanger human life and
health and adversely affect the operation of the these
components.
● Work on the Daikin Altherma EHS(X/H) (such as
maintenance or servicing) is only to be carried out
by persons who are authorised and who have
successfully completed qualifying technical or
vocational training and who have taken part in
advanced training sessions recognised by the
appropriate responsible authorities. These include
in particular certified heating engineers,
qualified electricians and HVAC specialists,
who because of their professional training and
expert knowledge, have experience in the profes-
sional installation and maintenance of heating,
cooling and air conditioning systems and heat
pumps.
