PERFECT FRY FIRE SUPPRESSION SYSTEM
PFS AUTOMATIC FIRE EXTINGUISHER
Note: Please refer to the PFS Automatic Extinguisher Installation, Inspection, Maintenance &
Recharge Manual (L20-361) for more detailed information.
The PFS must be stored above 32°F (0°C)
GENERAL DESCRIPTION
The PFS consists of a cylinder assembly (with pressure switch and gauge), actuating lever, fusible link as-
sembly, manual pull station, and two nozzles. It is designed and acceptable for use in areas that have ambi-
ent conditions between 32°F (0°C) and 120°F (50°C).
OPERATION
Automatic Operation
Upon the detection of a fire, the PFS will automatically operate. The fusible link rated at 250ºF (121ºC) 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 - PUL L”.
IMPORTANT:
The manual pull handle is to be pulled ONLY IN CASE OF FIRE in the
Perfect Fry PFC (use when the automatic system has failed).
NO TE: Power shut-off is also achieved by system operation. If the pressure
in the cylinder drops below 92 psi (6.3 bar), the pressure switch opens, deactivating the power relay causing
the appliance to de-energize.
INSPECTION & MAINTENANCE
The PFS must be serviced on a regular basis. Three types of servicing are required:
Monthly
An inspection or “quick check” must be conducted by the owner/operator and include verification of the follow -
ing:
1. The PFS is in its proper location.
2. The PFS shows no physical damage or condition that might prevent operation.
3. The pressure gauge is in the green operating range.
4. The maintenance tag is in place and is up to date.
5. The manual pull is unobstructed.
6. The nozzle blow-off caps are intact and undamaged.
Semi-Annually
The system must be inspected by authorized service personnel, as per NFPA 17A and include the following:
1. A check to see that the hazard has not changed.
2. Examination of the fusible link, cylinder, tubing, nozzles and all auxiliary equipment.
3. Fusible links must be replaced at least annually from the date of installation. They must be destroyed
when removed. They need to be replaced with the proper rated link. A fusible link loaded with grease or
other material can result in an excessive delay in actuation.
4. Verification that the agent distribution piping is not obstructed. Remove the blow-off caps from the nozzles
to ensure that they are free of grease build-up and inspect them for deterioration.
