PRINCIPLES OF OPERATION
CONTAMINANT CAPTURE
The primary purpose of any kitchen ventilator system
is to take objectionable odors, grease, steam and dust
particles from the cooking surface and transfer them
to an un-objectionable area.
The two most important considerations in achieving
contaminant capture are air velocity and volume.
Because one directly affects the other, each will determine
how well the ventilator captures contaminants and will
be fully explained in a following section of this manual.
GREASE EXTRACTION
Because of environmental concerns and regulations, it
is more important than ever before to remove as much
grease and unwanted contaminants as possible from
the air stream being expelled from the system. The
Water Wash Ventilator is one of the most effective in
grease removal on the market.
This is accomplished by centrifugal force as the air is
drawn through a series of bafes and forced to make
turns during which the grease particles impinge upon the
bafe plates. The grease will remain inside the ventilator
through the duration of the normal cooking cycle.
Centrifugal Grease Extraction
9
Water Wash Ventilator Owner’s Manual
Centrifugal grease extraction is the removal of grease
and dust from the air stream by means of centrifugal
action without any removable parts, moving parts, or
continuous, wasteful water spray.
At the termination of this cycle, the equipment is shut
down, and the ventilator will automatically clean the
grease from the system. This extraction is accomplished
without the use of lter media or moving parts to clog
with grease.
Because of this type of extraction, the Water Wash
Ventilator is well suited for commercial and industrial
applications and removes grease much more efciently
than bafe or mesh lter systems.
Extraction Chamber

Wash Ventilator With “Lazy Air” Make-up
Chamber
AUTOMATIC CLEANING
The grease and dust that accumulate within the
extraction chamber during operation of the ventilator
must be removed regularly. If allowed to accumulate
for long periods of time, the grease will “bake on” to
the interior of the ventilator forming a combustible
and difcult to remove coating. To prevent this build
up, the Water Wash Ventilator features an automatic
cleaning cycle this is initiated each time the exhaust
fan is turned off, or at the preset time during which
the Water Wash Mode Commander calls for a wash
cycle. When either of this situations occur, the exhaust
fan will stop. The ventilator damper will close and the
ventilator will be sprayed with a pressurized hot water
and detergent combination. The waste water will ow
from the system into an approved plumbing drain. This
will be explained in detail in the Sequence of Operations
section of the manual.
Thorough cleaning of the extraction chamber interior
is achieved by means of a pressurized hot detergent
water spray.

FIRE PROTECTION CYCLE
STANDARD PUSH BUTTON CONTROL
In the event of a re in the cooking area under the
ventilator, the exhaust ductwork should be protected
to prevent the exhaust fan from spreading the re to
the ductwork and the building roof. The Water Wash
Ventilator features an automatic re protection cycle to
contain res under the canopy to prevent their spread.
The re protection cycle is automatically initiated by
thermostats located in the exhaust air path at the duct
collars of the ventilator.
Location of Fire Detection Thermostats
As a back up, there is a remote re pull furnished near
a door. When pulled, this device will provide the same
results as the automatic re cycle.
Remote Fire Pull
In case of re, pull for the instant activation of the
Ventilator Fire Cycle.

SEQUENCE OF OPERATION
STANDARD CONTROL PANEL
Contaminants accumulated during the normal cooking
cycles are washed from the system at the end of each
operating cycle. This can be achieved automatically
(through the used of the Mode Commander) or manually
by turning OFF the exhausts fans using the Standard
Control Panel.
CAUTION: Always turn cooking equipment
off 15 minutes prior to shutting down the
exhaust system.
This will prevent accidental tripping of the appliance
re suppression system due to heat build-up when the
exhaust system is terminated.

WASH CYCLE PROCEDURE
1. Turn off all cooking appliances and allow to cool
for minimum of 15 minutes.
2. Press the STOP & WASH button.
Water Wash Ventilator Controller
• The exhaust fan will coast to a stop
• The supply fan (if required) will stop.
Inlet Damper Location
• The wash solenoid valve will open and the detergent
pump will start.
• Hot detergent water (120°F @40 psi) will be injected
through the spray nozzles for a predetermined
period of time.
• When the wash cycle ends, the wash solenoid
closes terminating water ow, and the detergent
pump stops. The inlet damper will remain closed
awaiting the next fan cycle.
• When the Mode Commander is furnished, up to
four wash sequences may be run consecutively.
FAN CYCLE
Push the START button on the Control Panel.
• The inlet damper will close.
12
Water Wash Ventilator Controller
Water Wash Ventilator Owner’s Manual
• The Inlet damper will open.
• The Exhaust fan will start.
• Ventilator make-up air supply will start (if required).
• Turn on cooking appliances as needed.
CAUTION: Do not turn on cooking appliances if
inlet damper is closed or exhaust fan is not running.
Failure to comply my result in an accidental re
suppression discharge.
MODE COMMANDER
MANUAL MODE:
VENT #1 ON Damper opens, fan starts
VENT #1 STOP Fan stops, damper closes,
timed wash begins. Wash ends
after elapsed time, fan remains
OFF.
VENT #1 WASH Same sequence as stop
sequence
All Water Wash systems have two separate means of
re suppression built in to protect the ventilator and
duct system should a re occur.
APPLIANCE PROTECTION
This is the rst line of defense in the event of a re.
Basically, there are three types which will be discussed
in detail in separate sections of this manual. They are
water mist, dry chemical and wet chemical. Each type
is designed for one purposes, suppression of out of
control cooking res.
DRY AND WET CHEMICAL SYSTEMS
The dry chemical and wet chemical systems make
use of remote re pulls, usually located near an exit,
which when pulled will activate the chemical solution.
VENT #1 FIRE Upon manual or thermal
activation, fan stops, damper
closes, continuous suppressive
spray initiates. Remains in this
state until manual deactivated
by depressing the FIRE
RESET button.
NOTE: In order to deactivate re suppression,
the temperature in the extraction chamber must
be below 325°F.
NOTE: When multiple ventilators are supplied
with single fan systems, all sequences are
simultaneous with the exception of re status,
which remains individual.
VENT #1: Fan sequence is automatically initiated at
programmed times.
NOTE: May be repeated up to three cycles in a
24-hour timeframe.
FIRE SUPPRESSION SYSTEMS
Typical Remote Fire Pull
They also employ fusible links which are located directly
above the cooking equipment.
Fusible Links above Appliances
When one of these links melt, the re suppression
system activates. When activated, wet or dry powder
13
Water Wash Ventilator Owner’s Manual
will be sprayed directly on the re through strategically
placed nozzles located above the appliances. Once
the chemicals are discharged, the gas valve will be
electrically or mechanically closed and the exhaust and
supply fans can be shut down or remain in operations
dependent upon local jurisdictional authority. Once
these systems are activated, the chemicals must be
replaced along with all fusible links which have been
affected. Once this is accomplished the gas valve can
be reset and normal operation resumed.
WATER FOG SYSTEM
When water fog systems are specied, there are some
basic differences which that should be noted. The
sprinkler nozzles are point of use and do not utilize
remote pulls or fusible links.
WATER FOG
NOZZLES
All Water Wash Ventilators utilize built in methods
of re suppression acting separately of appliance
protection. In the event a re has not been suppressed
and is drawn into the extraction chamber causing
a temperature rise above 325°F (275°F on down
draft models), re-stat contacts will close, sending a
signal to the ventilator control panel. The following
sequences will occur.
1. The exhaust fan shuts off, stopping the induced
draft over the cooking equipment and preventing
re from being pulled into the ductwork.
2. The UL rated damper door at the inlet to the
extraction chamber closes and provides a barrier
to the re, preventing a heat induced draft from
rising up the exhaust shaft.
3. The water-detergent wash system is activated,
releasing its water spray within the ventilator to
quench any re, wash away grease and dust that
could support combustion, and cool the damper
and extraction chamber, protecting the ventilator
from heat damage.
4. The water spay continues until the thermostat(s)
cool below 325°F and the FIRE RESET button on
the ventilator control panel is reset,
Typical Water Fog System
When a nozzle vial is heated to the designated
temperature and breaks, a continuous water spray
begins. Unlike chemical systems, all nozzles do not
open unless each/all are heated. Water continues
to ow until it is manually stopped. As with chemical
systems, the gas or electric appliances will be shut
down along with the exhaust system as required. All
systems may be incorporated with automatic signaling
devices for alarms.

5. A remote manual re pull switch is provided for
mounting in the exit path of the kitchen area. This
switch activates the re protection cycle. The re
switch (ber disc or glass bar) must be replaced
and the FIRE RESET button pushed before the
ventilation system can be restarted. If a remote
manual re switch or other device (such as a re
suppression system) activates the re protection
cycle, this device must also be reset to normal or
supervisory status before the FIRE RESET button
on the control panel will have any effect.
