● Before commissioning the re extinguishing system, remove the electrical
actuator from the container valve of the re extinguisher cylinder. This prevents
the extinguishant release due to misoperations, and prevents accidental
damage during the commissioning. After the commissioning of the
re
extinguishing system, reinstall the container valve to the electrical actuator.
● To avoid damage to the heat detector, keep a proper distance between the
heating device and the heat detector during the commissioning.
