Hydraulic Connection - Daikin EKHHP300A2V3 Manuel D'installation Et D'utilisation

2 x Set-up and installation
CAUTION!
If the DAIKIN EKHHP is not erected adequately
lower the flat solar panels (the top edge of the of the
storage tank is higher than the bottom edge of the
solar panels), the unpressurised solar system in the
outdoor area will be unable to drain completely.
● Erect the DAIKIN EKHHP with a DrainBack solar
connection at a sufficient depth to the flat solar
panels (observe the minimum gradient in the solar
connecting lines).
● Remove packing and dispose of it in an environment-friendly
manner.
● Remove the cover plates on the storage tank (fig. 2-2, item B)
and unscrew the threaded pieces (fig. 2-2, item F) from the
apertures on which the handles are to be mounted.
● Screw handles (fig. 2-2, item A) into the threaded holes that
are now free.

● Install the DAIKIN EKHHP at the installation site.
– Recommended distances:
To the wall (rear): ≥200 mm.
To the ceiling: ≥200 mm.
– Observe the tilt dimension (see section 8).
– Carefully transport the, use the handles.
– When setting up the unit in a cabinet, behind panels or in
other restricted conditions, sufficient ventilation
(e.g., using ventilation gratings) must be ensured.
– To avoid a circulation line, install DAIKIN EKHHP close to
the draw-off location.

2.4 Hydraulic connection

CAUTION!
If the DAIKIN EKHHP is connected to a cold water line,
where steel pipes are used, chips can enter the
special steel corrugated pipe heat exchanger and
remain there. This can lead to contact corrosion
damage and subsequently to leakage.
● Flush the feed pipes before filling the heat
exchanger.
● Install contamination filter in the cold water feed
(see chapter 1.5.5).
ONLY DAIKIN EKHHP500AA2V3
CAUTION!
If the heat exchanger for charging the pressurised
solar system (see overview image on page 2,
item 4+5) has an external heating unit (e.g. wood-
burning boiler) connected to it, an excessive flow tem-
perature at these connections can damage or destroy
the DAIKIN EKHHP.
● The feed flow temperature of the external heater
should be limited to max. 95°C.
Requirement: Optional accessories (e.g. Solar) mounted on the
DAIKIN EKHHP according to the specifications in the instructions
included with the delivery.
● Check the cold water connection pressure (maximum 6 bar).
– At higher pressure in the drinking water line, a pressure
reducer must be installed.
● Remove the cover on the
DAIKIN EKHHP.
● When using circulation brakes, fit them into the pipe
connections on the DAIKIN EKHHP.
● Create hydraulic connections on the DAIKIN EKHHP
(see fig. 2-5).
– Take the position and dimensions of the connections from
the overview image on page 2 and tab. 0-1 on page 3.

cover.
