 Taking out of operation

4. Place a suitable collection trough beneath the filling and 

emptying fitting.

6.2.4 Draining the heating circuit and hot water 

circuit

Connect the drain hose to the Daikin heat generator.

Allow the heating and hot water circuits to drain using the 
suction lifter method.

Disconnect the heating flow and return and the cold water 
feed and hot water discharge from the Daikin EKHWP / 
EKHWC / EKHWD.

Connect the discharge hose on the heating flow and return 
flow as well as the cold water inflow and hot water outflow so 
that the hose opening is at ground level.

Allow the individual heat exchangers to run empty one after 
the other based on the suction lifter method.

6.2.5 Drain the solar panel circuit (only pressurised 

system) 

6.3

Final shutdown

Disconnect the Daikin EKHWP / EKHWC / EKHWD from all 
electrical and water connections.

Dismantle the Daikin EKHWP / EKHWC / EKHWD in 
accordance with the instruction manual (chapter 4 "Set-up 
and installation"
) in reverse order.

Dispose of the Daikin EKHWP / EKHWC / EKHWD in 
accordance with regulations.

Recommendations for disposal

CAUTION!

Storage water will gush out as soon as the seal-
ing plug is removed.
There is no valve and no non-return flap on the 
filling and draining connection.

5. Unscrew the threaded 

piece (fig. 6-5, item E) at 
the filling and draining 
connection, remove the 
plug (fig. 6-5, item F) and 
immediately screw in the 
pre-assembled hose 
connector (fig. 6-5, item C) 
back into the filling and 
draining connection.

Fig. 6-5

Working steps 4 + 5

CAUTION!

If heat transfer media containing glycol are ex-
posed to temperatures above 170 °C over an 
extended period, they will decompose or form 
silt. This may reduce the frost protection, affect 
the output of the solar system and damage com-
ponents of the system.

In the event of extended standstill of the solar 
panel circuit drain in accordance with the 
installation instructions of the regulating and 
pump unit.

Daikin, thanks to the environmentally friendly design of 
the EKHWP / EKHWC / EKHWD hot water storage 
tank, has established the preconditions to ensure envi-
ronmentally friendly disposal. Proper disposal in com-

pliance with the respective national regulations of the country of 
use is the responsibility of the user/owner.

The designation of the product means that electrical 
and electronic products may not be disposed of to-
gether with unsorted domestic waste.

Proper disposal in compliance with the respective 
national regulations of the country of use is the respon-

sibility of the user/owner.

Only a qualified technician may disassemble the system.

Disposal may only be carried out by a facility that specialises 
in reuse, recycling and recovery.

Further information is available from the installation company or 
the responsible local authorities.
