2 x Safety
Make sure that the safety valves comply with
the requirements of EN 12828 when
connecting on the heating side, and with the
requirements of EN 12897 when connecting
on the domestic water side.
Only original Daikin replacement parts may be
used.
When working on the hydraulics, you must
first drain the water or release the pressure
using the internal KFE valve. Otherwise hot
water can jet out under pressure and result in
injury.

2.4.2 Electrical installation

Electrical installation may be carried out only
by electrical engineers and in compliance with
the valid electro-technical guidelines as well
as the regulations of the relevant energy
supply company (EVU).
Compare the mains voltage (~230 V, 50 Hz or
~400 V, 50 Hz) indicated on the type plate
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 Altherma EHS(X/H) requires fluori-
nated greenhouse gas for its function.
For work on stationary refrigeration
systems (heat pumps) and air condi-
tioning systems, proof of expertise is re-
quired in the European Community ac-
cording 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 certificate 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.
Components and spare parts must at least
satisfy the technical requirements defined by
the manufacturer.
