Notes for maintenance

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!
Inspection, maintenance and repair work
should only be undertaken by an appro-
ved heating installation company.
Inspections / Maintenance work not car-
ried out can result in damage to proper-
ty and personal injury.
e Danger!
Risk of fatal electric shock from tou-
ching live connections! Before commen-
cing work on the heat pump, disconnect
the power supply (circuit breaker) and
secure it against being switched on
again inadvertently.
Only genuine Vaillant spare parts may be used for in-
spections, maintenance and repair work to ensure the
long-term availability of all functions of your Vaillant ap-
pliance 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.
