Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and household cleaning products.
Do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy the surfaces and could also damage the technical
components of the unit.
Maintenance of the unit
The cooling circuit of the heat pump requires no regular
maintenance.
According to EU regulation (EC) 842/2006 of May 17,
2006, leak inspections and maintenance of a log book
are required for certain heat pumps!
The criteria for conducting leak inspections and
maintaining a log book are based on the hermetic
impermeability of the cooling circuit and the refrigerant
capacity of the heat pump! No log book is required for
heat pumps with a refrigerant capacity of < 3kg. With all
other heat pumps, the log book is included with all other
delivered materials.
Log book for heat pumps, Section “Information
on use of the log book”.
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
filters, dirt traps) should be inspected as well as cleaned
as needed - at the very least annually - by a qualified
heating or cooling system technician.
Regularly check that the safety valve for the domestic
hot water tank is in proper working order.
It is a good idea to have a maintenance contract with a
heating installation company. The company will conduct
all required maintenance at regular intervals.
CLEANING AND FLUSHING OF UNIT COMPONENTS
CAUTION!
Unit components may be cleaned

technical data of the manufacturer of the
heat exchanger.
Malfunctions
In the event of a malfunction, you can detect the cause
of the malfunction via the diagnostic program of the
