2 Safety
Only use the unit if it is in perfect technical condition
and only use it as intended, safely and aware of the
hazards and under full observance of this operating
manual.
2.1 Intended use
The unit is intended exclusively for the following func-
tions:
●Heating
● Domestichotwaterpreparation(optional,withac-
cessories)
●Cooling, reversible
►Intended use includes complying with the operating
conditions(“Technical data/scope of supply” on
page 19) and the operating manual and observ-
ing the reference documents.
►If local regulations apply, observe: laws, standards
and directives.
All other use of the unit is interpreted as not intended.
2.2 Personnelqualications
All instructions and information in this operating manu-
alareintendedexcusivelyforqualiedandskilledper-
sonnel.
Onlyqualiedand skilled personnel areabletocarry
out the work on the unit safety and correctly. Interfer-
encebyunqualiedpersonnelcanresultinfatalinju-
ries and material damage.
►Ensure that the personnel are familiar with the lo-
cal regulations, especially those relating to work-
ing safely and in awareness of the hazard risks.
►Have work on the electrical and electronic compo-
nentscarriedoutonlybyqualiedpersonnelwith
“electrical” training.
►Have any other work on the system carried out
onlybyqualiedandskilledpersonnel,e.g.
●Heating installers
●Plumbers
● Refrigeration plant manufacturers (maintenance
work)
During the warranty and guarantee period, servicing
and repair work may only be carried out by personnel
authorised by the manufacturer.
2.3 Personal protective equipment
There is a risk of cutting your hands on sharp edges of
the unit.
►Wear cut-resistant protective gloves during trans-
port.
2.4 Residual risks
Injuries caused by electric current
Components in the unit are live with fatal voltage. Be-
fore opening the unit casing:
►Disconnect the unit from power supply.
►Protect the unit against being switched back on
again.
►Residual voltage at the inverter. Wait for 90 sec-
onds before opening the unit.
Risk of injury from moving parts
►Only switch on the unit with air ducts and weather
protectiongridtted.
Injuries and environmental damage due to
refrigerant
The unit contains harmful and environmentally danger-
ous refrigerant. If refrigerant leaks out of the unit:
1. Switch off the unit.
2. Notify authorised after sales service.

2.5 Disposal
Environmentally hazardous media
Improper disposal of environmentally hazardous me-
dia(refrigerant)willdamagetheenvironment:
►Collect media safely.
►Dispose of the media in an environmentally sound
manner in accordance with to the local regula-
tions.
2.6 Avoid material damage
The ambient air at the heat pump’s installation site,
as well as the air drawn in as a heat source, must not
contain any corrosive components!
Constituents such as:
●Ammonia
●Sulphur
●Chlorine
●Salt
● Sewagegases,uegases
can cause damage to the heat pump, which can even
result in the complete failure/total loss of the heat
pump.
Decommissioning/draining the heating
If the system/heat pump is decommissioned or drained
after already being lled, it must be ensured that the
condenser and any heat exchangers have been
drained completely for the event of freezing temper-
atures. Residual water in heat exchangers and con-
densers can result in damage to the components.
►Completely drain the system and the condenser,
and open vent valves.
►Blow them clear with compressed air, if required.
Improper action
Requirements for minimum scale and corrosion dam-
age in hot water heating systems:
●Professional planning and commissioning
●Closed system with regard to corrosion
●Integration of an adequately dimensioned pres-
sure maintenance
●Use of demineralized water heating water or
VDI 2035 water
●Regular servicing and maintenance
If a system is not planned, commissioned and operat-
ed in accordance with the given requirements, there
will be a risk of the following damage and malfunctions:
●Malfunctions and failure of components, e.g.
pumps, valves
●Internal and external leaks, e.g. at heat exchangers
●Reduction in cross-section and blockages in com-
ponents, e.g. heat exchangers, pipes, pumps
●Material fatigue
● Gas bubble and gas cushion development (cavi-
tation)
●Negative effect on heat transfer, e.g. due to forma-
tion of deposits, and associated noises, e.g. boil-
ingnoises,ownoises
►Observe the information in this operating manual
for all work on and with the unit.
Unsuitablequalityofthewaterforllingup
and replenishing the heating circuit
Theefciencyofthesystemandtheservicelifeofthe
heat generator and the heating components depend
decisively on the quality of the heating water.
Ifthesystemislledwithuntreateddrinkingwater,cal-
cium deposits will form as scale. Lime scale deposits
accumulate on the heat transfer surfaces of the heat-
ing. The efciency is reduced and energy costs in-
crease. In extreme cases, the heat exchangers will be
damaged.
►Fill the system only with demineralized heating
water or VDI 2035 water.
