DANGER
FIRE HAZARD
Fire suppression system
must be charged and certified
by an authorized Ansul®
distributor.
DO NOT attempt to modify or
bypass the fire suppression
system.
An uncontrolled fire can
cause serious injury or death.
NOTE:
Ansul Deployments are not
covered under warranty.
Technical service needs to
be contacted immediately
and a deployment kit of parts
needs to be replaced before
unit is put back in service. If
the fire suppression system
is discharged, a buzzer will
sound continuously. The
unit will remain inoperable
until the fire suppression
system is serviced, recharged
and reset by an authorized
Ansul® distributor.
Charging of the Ansul®
Fire Suppression system
must be in accordance with
Ansul® Design, Installation,
Recharge and Maintenance
Manual, #418087.
NOTE:
If a REMOTE MANUAL PULL
STATION is installed, moving
the ventilator for any reason
may cause the Ansul®
system to discharge.
IMPORTANT:
Should the fire suppression
system discharge: all
nozzles must be replaced,
and all lines thoroughly
cleaned, prior to recharging
the system. Residual fire
suppression media may
compromise the flow and
dispersion of fire suppression
media in any subsequent
activation.
The alarm relay is activated by the Ansul® fire detection system. If the
installation includes a building alarm system, connect to terminals T7 &
T8 of the terminal block in supply connection box. These terminals are
configured from the factory for normally open operation.
The ventilator will operate properly, and the appliance control relay will
be energized, only when:
1. The VENTILATOR POWER SWITCH is "ON".
2. The Ansul® Fire Suppression System is charged and armed.
3. All filters are in position and serviceable, and the ventilator air flow
system is satisfied.
FIRE SUPPRESSION SYSTEM INSTALLATION
EACH 4' FOOT SECTION OF THE FIRE SUPPRESSION SYSTEM
is comprised of two containers of Ansulex® Low pH liquid fire
suppression media and a system pressurization canister, plus
associated plumbing. Actuation controls are contained in the Automan
enclosure.
The hood is supplied with a field installed 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 fire
suppression system.
Six (WVU48) NOZZLES disperse the fire suppression media. Two inner
nozzles protect the fan and plenum.
The appliance nozzles are 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.
The fire detection system utilizes six (WVU48) electronic thermal
detectors with an actuation set point of 225°F (107°C) in the upper
hood locations and 275°F (135°C) detectors in the lower wall locations.
The signaling from any of these detection devices will automatically
discharge the fire suppression media through all nozzles, disable the
cooking appliances and cause the alarm to sound.
Fire suppression media will form an emulsion designed to both smother
and cool the fuels in/on the cooking appliance.
Ansul® Deployments are not covered under warranty. Technical service
needs to be contacted immediately and a deployment kit of parts needs
to be replaced before unit is put back in service. Any Ansul® media
must be throughly cleaned from every area of the unit before it can be
put back into service.
