REQUIREMENTS
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
Your product is marked with this symbol. This means that
electrical and electronic products shall not be mixed with
unsorted household waste.
Do not try to dismantle the system yourself: the dismantling of the
system, treatment of the refrigerant, of oil and other parts must be
done by a qualified installer in accordance with relevant local and
national legislation.
Units must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed off
correctly, you will help to prevent potential negative consequences for
the environment and human health. Please contact the installer or
local authority for more information.
During longer periods of standstill, e.g. during summer with
a heating only application or during longer periods when
there is no need of an operating unit, it is very important
NOT TO SWITCH OFF THE POWER SUPPLY towards the
unit.
Switching off the power supply stops the automatic
repetitive movement of the motor in order to prevent it from
getting jammed.
In case of a power supply failure or pump operating failure,
drain the system (as suggested in the figure below).
When water is at standstill inside the system, freezing up is
very likely to happen and damaging the system in the
proces.
