2.4 Duty to inform
READING THE OPERATION
M
ANUAL
Every person performing any tasks on the system is required to read
the Operation Manual prior to beginning work, particularly the
chapter “2 Safety instructions”.
This especially applies to persons who only occasionally work on the
heating system, e.g. when cleaning or servicing it.
The Operation Manual must always be kept readily accessible at the
heating system's installation site.
