    Semi-Annual Maintenance is required for all Pre-engineered Fire Suppression Systems.

*6 year Maintenance is required every 6 years from either the date of manufacture or the last year of service

**Hydro-test of the cylinder is required every twelve years from the date of manufacture.

Finding the date of manufacture:
The date is either on the label or stamped on the bottom, or around the neck of the cylinder.
For example "00" indicates 2000 the cylinder is due for a 6 year maintenance "94" would indicate 1994 the cylinder is due for a 12 year hydro-test.
Note: sometimes the stamped date is so faint on the bottom it can only be seen at a specific angle in the light.
