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. Becauseonedirectlyaffectstheother,eachwilldetermine how well the ventilator captures contaminants and will be fully explained in a following section of this manual.
GREASE EXTRACTION
Becauseofenvironmentalconcernsandregulations,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 baffles and forced to make turnsduringwhichthegreaseparticlesimpingeuponthe
baffleplates.Thegreasewillremaininsidetheventilator 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 greasefromthesystem.Thisextractionisaccomplished without the use of filter 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 applicationsandremovesgreasemuchmoreefficiently than baffle or mesh filter systems.
Extraction Chamber
Thorough cleaning of the extraction chamber interior is achieved by means of a pressurized hot detergent water spray.
Model SWFM Hi-Velocity Wall Style Water
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 difficult 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.Wheneitherofthissituationsoccur,theexhaust 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 flow fromthesystemintoanapprovedplumbingdrain.This willbeexplainedindetailintheSequenceofOperations section of the manual.

FIRE PROTECTION CYCLE
STANDARD PUSH BUTTON CONTROL
In the event of a fire in the cooking area under the ventilator, the exhaust ductwork should be protected to prevent the exhaust fan from spreading the fire to the ductwork and the building roof. The Water Wash Ventilatorfeaturesanautomaticfireprotectioncycleto contain fires under the canopy to prevent their spread. The fire protection cycle is automatically initiated by thermostats located in the exhaust air path at the duct collars of the ventilator.

SEQUENCE OF OPERATION
STANDARD CONTROL PANEL
Contaminantsaccumulatedduringthenormalcooking cycles are washed from the system at the end of each operating cycle. This can be achieved automatically (throughtheusedoftheModeCommander)ormanually 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 fire suppression system due to heat build-up when the exhaust system is terminated.

FIRE SUPPRESSION SYSTEMS
Water Wash Ventilator Owner’s Manual
All Water Wash systems have two separate means of fire suppression built in to protect the ventilator and duct system should a fire occur.
APPLIANCE PROTECTION
This is the first line of defense in the event of a fire. Basically,therearethreetypeswhichwillbediscussed 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 fires.
DRY AND WET CHEMICAL SYSTEMS
The dry chemical and wet chemical systems make use of remote fire pulls, usually located near an exit, which when pulled will activate the chemical solution.
Typical Remote Fire Pull
Theyalsoemployfusiblelinkswhicharelocateddirectly above the cooking equipment.
Fusible Links above Appliances
When one of these links melt, the fire suppression system activates. When activated, wet or dry powder
13
Water Wash Ventilator Owner’s Manual
will be sprayed directly on the fire through strategically placed nozzles located above the appliances. Once the chemicals are discharged, the gas valve will be electricallyormechanicallyclosedandtheexhaustand 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
Whenwaterfogsystemsarespecified,therearesome 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 |
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 flow 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 systemsmaybeincorporatedwithautomaticsignaling devices for alarms.
WATER WASH FIRE SUPPRESSION
All Water Wash Ventilators utilize built in methods of fire suppression acting separately of appliance protection.Intheeventafirehasnotbeensuppressed and is drawn into the extraction chamber causing a temperature rise above 325°F (275°F on down draft models), fire-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 fire 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 fire, 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 fire, 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,

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

Basically the cabinet is divided into twosections:Theelectricalcompartmentontheleftside and the plumbing components on the right. For ease in identification the components will be discussed in separate sections: Electrical Compartment, Plumbing Compartment, Externally Mounted Components, and Ventilator Mounted Components.
PUSH BUTTON CONTROL
All system functions are controlled by the Push Button
