the unit have read and understood these instructions. In
addition, he must also train personnel and inform them of
the possible dangers at regular intervals.
It is the responsibility of the operator to provide
maintenance and repair personnel with the necessary
personal protective equipment and advise them of the
necessity to wear it.
DANGER!
Risk of fatal injury from electrocution!
Contact with live parts will lead to fatal injury
from electrocution. Damage to the insulation or
individual components can lead to a fatal injury.
–Onlypermitqualiedelectricianstoworkonthe
electrics
– Immediate disconnect the system and repair in the
event of damage to the insulation.

Limits for tap water
3.6 Sound Values
3.7 Limits of the Medium (LPHW and CHW)
The sound levels change depending on the fan speed.
The sound pressure levels were calculated at an assumed room
insulation of 8 dB(A). This corresponds to a distance of 2 m,
a room volume of 100 m³ and a reverberation time of 0.5 s
(in accordance with VDI 2081).
Only use water or a water-glycol mixture with up to 50%
glycol as the heating or cooling medium! Pay attention to the
suitability of the components on site, such as valves, boilers etc.
Usenon-corrosiveandnon-ammableliquidsastheheating
and cooling medium.
Media limits
Use water or water/glycol (max. 50%) as the medium. The
