WARNING
!
Only qualified and instructed personnel can
install and handle the odorant tank.
The odorizing system must be installed,
operated and maintained in accordance to all
applicable rules and standards.
Follow the instructions, especially the ones
relevant to "pressure risk".
The installation, operation and maintenance
procedures, if not performed by qualified
personnel, can be dangerous.
These circumstances can lead to damage
to the devices, injuries to people or damage
to properties due to gas or liquid leakage.
If there is a leak in the system, the released
gas can accumulate and provoke fires
or explosions.
