– 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.
– 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).
If the installation conditions require the hydraulic
connection to be directly upwards, the cover
hood can be cut out along the broken line.

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).
