Instruction Manual
6.- CONFIGURATION
The correct operation of the
RECmax-CVM
depends on its correct adjustment�
Since it is a protection device, erroneous adjustment can compromise the protec-
tion of property and people� That is why it is very important that it is adjusted by
a trained technician to decide on the most appropriate type of protection in each
installation�
CIRCUTOR
accepts no responsibility for incorrect working of the device due to
erroneous adjustment
