If the installation conditions require the hydraulic
connection to be directly upwards, the cover
hood can be cut out along the broken line.
Fig. 2-4
Creating the hood cut-out
–
Pay attention to the stipulated tightening torque
(see section 2.1).
– Design the lines as such that the sound attenuation cowl
can be applied without any problem following assembly.
WARNING!
There is a danger of scalding at hot water tem-
peratures over 60°C. This is possible, when
solar energy is used, with a connected external
heating device, when the Legionella protection
is activated or when the domestic hot water
target temperature is set higher than 60°C.
● Install scald protection (hot water mixer).
– Water shortage protection: The temperature monitoring
of the controller safely switches off the DAIKIN EKHHP in
the event of a water shortage. No additional water short-
age protection is needed in the construction. Neverthe-
less, regular checking of the fill level is necessary in order
to ensure function as intended.
– Avoid damages caused by deposits and corrosion:
Observe the requirements for the buffer water storage
(see section 1.5.6).

● Carefully insulate pipe lines against heat loss and so as to
avoid the formation of condensation (insulation thickness at
least 20 mm).
