PFS INSTALLATION, INSPECTION, MAINTENANCE & RECHARGE MANUAL
GENERAL DESCRIPTION
The PFS consists of a cylinder assembly (with pressure switch and gauge), actuating lever, fusible link assembly, manual pull station, and two nozzles. It is designed and acceptable for use in areas that have ambient conditions between 0°C (32°F) and 50°C (120°F).
The PFS must be stored above 0°C (32°F)
OPERATION
Automatic Operation
Upon the detection of a fire, the PFS will automatically operate. The fusible link rated at
138ºC (280ºF) will operate when exposed to the fire and operate the PFS automatic extinguisher unit. When operated, the PFS unit will discharge wet chemical agent through the provided discharge piping and distribution nozzles.
Manual Operation
The PFS unit can also be operated manually by pulling the remote lever (to be mounted on the front of the cooking appliance) that is clearly marked “In Case Of Fire - PULL”.
Power shut-off is also achieved by system operation. If the pressure in the cylinder(s) drops below 92 psi, the pressure switch opens, deactivating the power relay causing the appliance to de-energize.
