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)
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.
