GENERAL DESCRIPTION
The Fire Suppression system is specifically
designed for controlling wet chemical fires
in the fryer.
The system consists of a cylinder assembly
(with pressure switch and gauge), actuating
lever, fusible link assembly, manual pull sta
-
tion and two nozzles.
AUTOMATIC OPERATION
Upon the detection of a fire, the system will
automatically operate. the fusible link in the
cooking area separates at a temperature of
280° F, which allows the spring to pull down
on the actuating lever. The valve stem is
pushed down releasing pressure and wet
chemical to the nozzles.
MANUAL OPERATION
When the manual pull handle on the front
panel is pulled, the system operates simi
-
larly by disconnecting the fusible link cable
from the actuating lever. The spring pulls
down on the lever releasing pressure and
wet chemical to the nozzles.
IMPORTANT:
The manual pull
handle is to be
pulled ONLY IN
CASE OF FIRE in
the fryer (use
when the auto
-
matic system
has failed)
.
If the pressure in the cylin -
der drops below 195 psi,
the pressure switch opens, deactivating the
power relay cutting all power to the fryer.
