5.7 Starting up the heat pump
The start-up of your heat pump was carried out after
installation by your expert technician company.
Your heat pump does not need to be started up again if
it disconnects from the mains unexpectedly, for example
as a result of a voltage drop (power cut, circuit breaker
defective, circuit breaker deactivated). Your geoTHERM
heat pump has an automatic reset function, i.e. the heat
pump reverts automatically to its starting condition,
provided no fault is present in the heat pump itself. Find
out what to do in the event of a fault in Chap. 5.12.
5.8 Shutting down the heat pump
The heat pump can only be switched off via the opera-
tor control panel by deactivating the heating and hot
water generation (operating mode "Off").

tem if you need to de-energise the heat

5.9 Inspection by a specialist engineer
In contrast to heaters based on fossil fuels, no expen-
sive maintenance work is necessary for the Vaillant geo-
THERM heat pump. However an annual inspection of the
system by a specialist is a prerequisite for continued
operational safety, reliability and a long working life.
d Danger!
If inspections are not carried out, this
can result in damage to property and
personal injury.
Only have inspections and repairs car-
ried out by an approved heating installa-
tion company.
h Note Have your system checked regular-
ly by an expert technician company to
ensure efficient operation of your heat
pump.
5.10 Inspection by the operator
In addition to the annual inspection by an expert, a
small amount of inspection work needs to be carried out
by the operator.
5.10.1 Checking the filling pressure of the heating
system
The filling pressure of the heating installation should be
checked at regular intervals.
