Maintenance Guide
 Semi-annual maintenance of the fire extinguishing system involves system commissioning.
Before the maintenance, inform the related administrative departments that the fire
extinguishing system will be maintained and stop working.

Before maintaining the fire extinguishing system, remove the electrical actuator from the
container valve of the fire cylinder. This prevents the extinguishant release due to
misoperations, and prevents accidental damage.

After the maintenance, reconnect the electrical actuator, and inform the administrative
departments that the fire extinguishing system has become operational.
