4.1.2 Draining the hot water circuit
● Close the cold water supply to the DAIKIN EKHHP.
● Separate the cold water supply pipe to the DAIKIN EKHHP
and allow the hot water distribution network to empty out.
● Isolate the cold water supply and hot water outlet from the
DAIKIN EKHHP.
● Connect drain hoses to cold water supply and hot water outlet
so that the end of the hose is located just above ground level.
● Allow heat exchanger to drain according to the siphon
principle.
4.2 Final shutdown
A final shutdown may be necessary if
– the system is defective and is being dismantled and disposed
of.
– components of the system are defective, are being disman-
tled and replaced.
– the system or parts of the system are being dismantled and
reassembled in another location.
The DAIKIN EKHHP is designed to be environmentally friendly
and easy to install: the jobs described above can therefore be
carried out in an efficient and environmentally-friendly manner.
When changing location or replacing parts on the coolant system
in the pipe network:
● Pump the coolant back into the external heat pump unit (see
installation and operating guide for the particular external
heat pump unit).
When disposing of the machine or replacing parts in the coolant
system:
● Suction the coolant from the machine and recycle (see instal-
lation and operating guide for the particular external heat
pump unit).
● Decommissioning a DAIKIN EKHHP (see section 4.1).
● Disconnect the DAIKIN EKHHP from all electrical connec-
tions, refrigerant and water connections.
● Dismantle the DAIKIN EKHHP or components in accordance
with the installation guide in reverse order.
● DAIKIN EKHHP disposed off in a professional manner.
Recommendations for disposal
The DAIKIN EKHHP has an environmentally friendly design.
During the disposal process, the only waste created is that which
can be used for material or thermal recycling. The materials used
that are suitable for recycling can be sorted into individual types.
WARNING!
Cooling systems (heat pumps), climate control
systems and heating devices that are incorrectly dis-
mantled can both endanger the life and health of
people and exhibit impaired function during start-up.
● Work on the DAIKIN EKHHP (such as dismantling
components, temporary or final shutdown of
system) is only to be carried out by persons who
are authorised and who have successfully
completed
qualifying technical or vocational
training
for the specific activity and who have
taken part in advanced training sessions recog-
nised by the relevant responsible authorities.
These include, in particular,
certified heating
engineers, qualified electricians and HVAC
specialists
, who on account of their
professional
training
and
expert knowledge
, have experience
in the professional installation and maintenance of
heating, cooling and air conditioning systems and
heat pumps.
● You
must observe
the
warning and safety
instructions
in the installation manual on working
in the coolant system.
CAUTION!
Coolant escaping from the system causes long-term
damage to the environment.
Mixing different kinds of coolant can result in hazard-
ous toxic gases being released. Mixing with oils when
coolant escapes can lead to the soil being contami-
nated.
● Never allow coolant to be released into the atmos-
phere - always suction it off and recycle using a
suitable recycling device.
● Always recycle coolant, in so doing keeping it
separated from oils and other additives.
● Only store different types of coolant separately, in
suitable pressure vessels.
● Dispose of coolants, oils and additives properly
and in accordance with the applicable national
regulations of the country it is being used in.
