Service and maintenance

9.1 General

Regular inspection and maintenance of the DAIKIN EKHHP re-
duces 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 re-
frigerant 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 Ar-
ticle 3 and 4, operators (owners) must service their fixed refriger-
ation 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.
Operators of DAIKIN heat pump systems are subject to the
following obligations:
DAIKIN EKHHP(3/5)00AA2V3
DAIKIN Hot water heat pump
008.1423444_05 – 08/2016
9 x Service and maintenance
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 mainte-
nance contract, including documentation of the work carried out
in the operating manual in order to preserve the right to guaran-
tee, 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 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.
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 cor-
rection, 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.
