WARNINGS
Actuation of the FM-200 System in the emergency discharge
mode will result in bypassing of the 60 second time delay and
pressure switches. The automatic equipment shutdowns, electric
horn/strobe, warning lights (amber strobe), and warning bell will
not function. FM-200 will be discharged immediately.
Operate the pressure switches by manually lifting the plunger
located on the top of the pressure switches to shutdown equipment.
Failure to observe these warnings could result in death or serious
injury.
To reduce temperatures within the protected space and manage
the risk of HF exposure to humans, the WWS is designed and intended
to be operated for a minimum of 15 minutes. This procedure should
be followed to the full extent or death or serious injury could occur.
NOTE
The engine room FM-200 system is augmented with an installed
WWS. If necessary, the FM-200 system could be used as a stand
alone system.
Operate the WWS for a minimum of fifteen (15) minutes. During the WWS operating
period, approximately every three (3) minutes, open valve WWS-2, Engine Room WWS
Strainer Blow Off for approximately ten (10) seconds. This will allow any foreign matter
to be flushed from the strainer basket.
