DANGER
BURN
HAZARD
Any additional remote pull station
must NOT be installed on the
front of the cooking appliances,
nor forward of the ventilator side
panels.
Discharge of the re
extinguishing system into hot
grease or oil may cause hot
foam to spill over from the
cooking surface or frypot.
Serious burns and other injuries
can result from contact with hot
oil and from slipping in spilled oil.
Manual pull station is factory
installed on the left side (facing
the unit. It may, however,
be relocated to the right side
of the ventilator hood by an
authorized Ansul® agent.
FIRE SUPPRESSION SYSTEM INSTALLATION
FIRE SUPPRESSION SYSTEM is comprised of a container of
Ansulex® Low pH liquid re suppression media and a system
pressurization canister, plus associated plumbing. Actuation controls
are located behind the front access panel.
Two FUSIBLE LINKS are utilized for automatic actuation of the re
suppression system. Additionally, the hood is supplied with a MANUAL
PULL STATION, which must be set-up at the time of installation by an
authorized Ansul® distributor.
The MANUAL PULL STATION allows for for manual emergency
shutdown of cooking appliance power, and actuation of the re
suppression system.
Three NOZZLES disperse the re suppression media. Two inner
nozzles protect the fan and plenum. The third, front mounted, nozzle is
swivel mounted, and must be directed toward the cooking surface of the
installed cooking appliance.
If the ventilator is situated such that the supplied manual pull station
cannot be installed or is not readily accessible, a REMOTE MANUAL
PULL STATION may be required by local codes. Any such remote
manual pull station must be installed by an authorized Ansul®
distributor in accordance with the AUTHORITY HAVING JURISDICTION
When the re suppression system discharges, the cooking appliance
contactor is de-energized; and, the re suppression media is
discharged. Fire supression media will form an emulsion designed to
both smother and cool the fuels in/on the cooking appliance.
Two fusible links are used to detect re. One (165ºF) is located
between the grease bafe and lter pack, and is for protection from
a cooking appliance re. The other (212ºF) is located in the lter
plenum, and will protect against a re in the plenum. Either link melting
will discharge the re suppression media through all nozzles, disable
the cooking appliance and cause a buzzer to sound.
The MANUAL PULL STATION and any similar REMOTE MANUAL
PULL STATION will activate the re suppression system when the ring
on the pull station is pulled to its full extent.
