5.7
Starting up the heat pump
The start-up of your heat pump was carried out after in-
stallation by your expert technician company.
A repeated start-up will not even be necessary in the
event that your heat pump disconnects from the mains
unexpectedly, for example as a result of a voltage drop
(power cut, circuit breaker defective, circuit breaker de-
activated). Your geoTHERM heat pump has an automat-
ic reset function, i.e. the heat pump reverts automatical-
ly 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. 5.10.
5.8
Shutting down the heat pump
The heat pump can only be shut down via the control
panel by deactivating the heating and hot water genera-
tion functions in the respective menus (see
Chap. 5.4 Displays at user level).
h
Note!
Should it be necessary to remove all
electric power from the heat pump in-
stallation, then switch off the circuit
breaker on your heating system.
5.9 Inspection
An annual inspection/maintenance of the unit by a spe-
cialist is a prerequisite for continuing operational safety,
reliability and a long working life.
d
Danger!
Inspections / Maintenance work not car-
ried out can result in damage to proper-
ty and personal injury.
Have inspections maintenance and re-
pairs carried out only by a recognised
expert technician company.
Only genuine Vaillant spare parts may be used for in-
spections, maintenance and repair work to ensure the
perfect long-term working order of all functions of your
Vaillant appliance and to prevent the approved series
condition from being changed.
Any spare parts which might be required are listed in
the relevant current spare parts catalogues.
Information can be obtained from Vaillant Customer
Service Centres.
