CAUTION:
FIRE HAZARD
HEALTH HAZARD
The cooking appliance must
be connected to the cooking
appliance contactor, the
control circuit of which is
controlled by the ventilator.
Failure to control cooking
appliances will provide no
protection in the event of a
re, nor will cooking vapors
and odors be contained in
the event of ventilator hood
malfunction.
ELECTRICAL INSTALLATION
Refer to the nameplate on the ventilator. Verify ELECTRICAL
SERVICE POWER. Voltage and phase must match the nameplate
specications, and available electrical service amperage must meet or
exceed the listed amperage. Refer to specications listed on page 1
of this manual.
The ground lug of this ventilator must be connected to a suitable
building ground.
Remove the lower rear panel to access the cooking appliance
contactor and building alarm relay. Remove the appropriate knockout,
then wire the cooking appliance to the LOAD side of the contactor.
NOTE: If the provided power cord is not used, it is the responsibility
of the electrical contractor to provide suitable wiring, exible or ridgid
conduit, and an appropriate strain relief.
The cooking appliance under the ventilator hood must be connected
to the LOAD side of the cooking appliance contactor, located in the
electrical connection box. The contactor functions control the cooking
applance in the event of ventilator malfunction or appliance re.
The ventilator provides a dry contact relay connection for a building re
management system. This pilot-duty relay may be required by local
re codes, however, Wells Bloomeld strongly recommends that such
system be properly utilized in any case.
The alarm relay is activated by the Ansul® re detection system. If the
installation includes a building alarm system, connect to either the N.O.
or N.C. contacts of the relay (as required by the building alarm system).
The ventilator will operate properly, and the 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. The grease bafe and lter pack are in position and serviceable,
and the ventilator pressure sensing system is satised.

INSTALLATION
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 for each module, plus associated plumbing.
Actuation controls are contained in the Automan enclosure.
Two FUSIBLE LINKS are utilized for automatic actuation of the re
suppression system. Additionally, the hood is supplied with a eld
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 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, cooking appliance
contactor and building re alarm relay are de-energized; and, the re
suppression media discharged. Fire supression media will form an
emulsion designed to both smother and cool the fuels in/on the cooking
appliance.
DANGER
FIRE HAZARD
Fire suppression system
must be charged and certied
by an authorized Ansul®
distributor.
DO NOT attempt to modify or
bypass the re suppression
system.
An uncontrolled re can
cause serious injury or death.
NOTE:
If the re suppression system
is discharged, a buzzer will
sound continuously. The unit
will remain inoperable until
the re 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.
M521 p/n 2M-Z17085 OpM WVU- Universal Hood
IMPORTANT:
Should the re suppression
system discharge: all nozzles
must be replaced, and all
lines thoroughly cleaned,
prior to recharging the
system.
Residual re suppression
media may compromise the
ow and dispersion of re
suppression media in any
subsequent activation.
