Instructions For Operating Safety; Before Working On The Hydraulic System; Electrical Installation; Working On Cooling Systems (Heat Pump) - Daikin EKHHP300AA2V3 Installation And Operating Instructions Manual

Any other use outside the intended use is con-
sidered as improper. The operator alone shall
bear responsibility for any resulting damage.
Intended use also includes compliance with the
maintenance and service conditions. Spare
parts must at least satisfy the technical require-
ments defined by the manufacturer. This is the
case, for example, with original spare parts.

2.4 Instructions for operating safety

2.4.1 Before working on the hydraulic system

● Work on the DAIKIN EKHHP (such as setup,
servicing, connection and initial start-up) 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 appro-
priate responsible authorities for the specific
activitiy. This, in particular, includes heating
specialists and climate control technicians
who have experience, as a result of their
technical training and their knowledge of the
subject, of proper and appropriate installation
and maintenance of heating, climate control
and cooling installations and heat pumps.
Switch off the external main switch before
starting any work on the DAIKIN EKHHP and
secure it against unintentional switch-on.
● Seals must not be damaged or removed.
● The domestic water connection must comply
with the requirements of EN 12897.
● Only original DAIKIN replacement parts may
be used.

2.4.2 Electrical installation

● Electrical installation must be carried out only
by qualified electrical experts and in
compliance with the valid electro-technical
guidelines as well as the regulations of the
relevant energy supply company (EVU).
● Make up the power supply in accordance with
IEC 60335-1, overvoltage category III. Means
with contact separation in all poles that
provide full disconnection must be incorpo-
rated in the fixed wiring in accordance with the
wiring rules.
● Compare the mains voltage (~230 V, 50 Hz)
indicated on the nameplate with the supply
voltage before connecting to the mains.

● Before beginning work on live parts,
disconnect all of the systems circuits from the
power supply (switch off main switch,
disconnect fuse) and secure against uninten-
tional restart.
● Equipment covers and service panels must be
replaced as soon as the work is completed.
2.4.3 Working on cooling systems (heat
pump)
The DAIKIN EKHHP requires fluorinated green-
house gas for its function.
For work on stationary refrigeration sys-
tems (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 certifi-
cate category II
– 3 kg coolant fill quantity or over: Expert cer-
tificate category I
● Always wear safety goggles and protective
gloves.
● When 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.
● Do not let coolant come into contact with open
fire, embers or hot objects.
● Never allow coolant to escape into the atmos-
phere (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 refrig-
erant could escape.
● If you suspect leaks in the refrigerant circuit:
Never pump the refrigerant back into the heat
pump external unit with the internal
compressor - always extract with a suitable
recycling unit and recycle it.
● Components and spare parts must at least
satisfy the technical requirements defined by
the manufacturer.

2.4.4 Site of installation

For safe and fault-free operation, it is necessary
that the installation location of the DAIKIN
EKHHP fulfils the safety-relevant criteria de-
scribed exactly in Section 4.3.
