It is recommended that the exhaust fan remain on at the trne of discharge tn aid in the removal of smoke, gases and other airborne materials frorn the hazard area in the event of a fire. Electrostatic Precipitators (ESP) An Electrostatic Precipitator(ESP)is designed to remove smoke and odier airborne contaminants from the air flowing through the exhaust ductwork as ameans of pollution contrcl. Exhaust ductwork using ESPs requires ADP nozzle(s) upstream (prior to) and immediately downstream of the ESP. The downstream nozzle(s) must be located centrally in the duct-work and should be aimeJ at the middle of the ESP. Distribution piping tu the ADP nozzles must not interfere with the function of the ESP unit,ADP nozzle quantity is determineO by the duct size and configurallon as defined under Duct Protection (refer to "Duct Protection"on page 17). ` . — ^ - ' r � � / / ' Appliance Protection . The EVVC system utilizes both ovahapp|ngand dedicated nozzle appliance coverage, depending onthe type mf cooking appUanoe(n)requiring protection, Overlapping appliance coverage allows a given area under the hood, defined as the hazard zone, to be / protected by overlapping (TFl)nozzles that are evenly spaced, at the same height and alignment(front-to- back) � re|abve to the hazard zone. � Dedicated appliance protection, utilizes an ADP nozzle (or nozzles)for protection of an individual ` appliance. / Overlapping, dedicated appliance, plenum, and duct protection may be incorporated in a single pipe / network on the EVVC extinguishing system. � The following sections detail the different nozzle coverage and placement parameters for overlapping and dedicated nozzle appliance protection methodologies. Overlapping Appliance Protection A single hazard zone utilizing overlapping coverage is 30' deep, by the total length of the cooking surface of the protected appliances, The cooking surfaces of all appliances protected by overlapping nozzles must 1 be located within the defined hazard zones. Cooking appliances eligible for overlapping protection are / outlined in Table 4. The lowest and highest cooking surfaces will determine the height of the fire � suppression nozzles.All overlapping nozzles must be mounted at the same height in a single hazard zone. ' Overlapping protection useoTF1 nozzles only, ' For applications where overlapping protection cannot be used, such as an upright boiler,dedicated ' appliance protection must beused. � Group Protection ' Overlapping protection provides coverage for a continuous hazard zone, with all TF1 nozzles atconsistent � position (ie.zone oentedme). spacing, and height. / When there is an area within a hazard zone for which continuous overlapping coverage is not applicable, ' the overlapping protection zone must be ended, and a new zone started for the new group of appliances, ' Examples where continuous protection is interrupted include a counter, storage or prep area, appliance ' not requiring protection (e.g.enclosed oven) oran appliance requiring dedicated appliance coverage. ' Refer to Figure 24, Figure 25, Figure 26 for details of group overlapping protection. , . . ^ �,. 21 ° Overlapping Protection For hazard zones that include one cv more deep fat fryers, the cmeManpingnozzle -nozzles bu spaced no ' more than 12" from each end of the appliance hazard an zone 24"on center.

The nozdeheight must be4O^tp45''above the appliance 'cooking surface, except for woks, where height is measured from the inside bo:tom of the wok. The appliance cooking surfaces within a protected group are to all bmat the same e|evation. The nozzles must be positioned along the total hazard zone length to allow protection of eec h appliance in the hazard zone.

Under normal conditions the"Fire System Activated" light is flashing one brief flash every 3 seconds, indicating the system is armed and ready. If a fault is detected anywhere in the system, , . i an audible alarm will periodically sound and the "Fire System Activated"light will flash a fault code to i indicate the fault that was detected. This fault code consists of a series of flashes followed by a pause. i Simply count the number of flashes between the pauses and refer to the chart below to find the cause of the fault.Any fault is extremely important and must be corrected and rectified immediately to insure proper operation of the fire system. The connections for building fire panels are located at AL1 and AL2 as dry contacts.

As-built wiring diagrams are furnished with each control package from'he factory and are either attached to the door of the unit or provided with the paperwork packet. Electrical wiring and connections must be made in accordance with local ordinances and the National Electric Code, ANSI/NFPA70. Verify the voltage and phase of the power supply and the wire amperage capacity is in accordance with the unit nameplate. ATTENTION: LOW-VOLTAGE DC OR SIGNALING WIRE SHOULD E:E ROUTED IN SEPARATE CONDUIT FROM ALL AC VOLTAGE SOURCES. 1, Always disconnect power before working on or near this equipment. Lock and tag the disconnect switch or breaker to prevent accidental power up, 2. There are multiple electrical connections required for this control. 120V AC should be wired to terminals H1 and Ni, If the hood is equipped with a separate light circuit, 120V AC should power this circuit per the as-built schematic. Fan wiring connections must be liade per the schematic. H1 and Ni should not be connected to a shunt trip breaker. 3. Make certain that the power source is compatible with the requirerr ents of your equipment.The system wiring schematic identifies the proper phase and voltage of the equipment. 4. Prior to connecting the control package to a power source, verify power line wiring is de-energized. 5. Secure the power cable to prevent contact with sharp objects. 6. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces or chemicals. Release solenoid cables must not come in contact wilt hood surfaces. 7. If the control package is a wall-mount system, a duct mounted temperature sensor will need to be wired. The temperature sensor must be wired to terminal blocks as indicated on the wiring schematic. 8. If the system contains additional firestats, they must be wired into tie supervised loop. 9. If the control is a wall-mount system, the hood lights wiring will need to be wired to terminals 13"and "W". Verify connections on wiring schematic. 10. Before powering up the system, make sure that the interior of the control package is free of loose debris or shipping materials, 11. If 3 phase motors are spinning in the incorrect direction,switch ary two wires on the output of the motor starter. If single phase motors, rewire per the motor schema'ic to change direction. 12.

However, any food or cooking oils that have been contaminated with wet chemical agent should be discarded. Refer to Safety Data Sheet( IDS). After any system discharge, it is best to clean the area as soon as it is safe to do so. Prolonged exposure of equipment to wet chemical can result in localized corrosion due to meisture in the air. Clean up should be completed within 24 hours of any system discharge. EWC cylinders need to be recharged or replaced every 12 years, and after any system discharge. Appliance Cleanup No unusual cleanup procedure is required.The reaction of the wet agent and the grease is one of saponification and it produces a foam which can be wiped off. After the appliances have completely cooled, the residue from the discharge may be cleaned up using a wet cloth or sponge.Ensure that all fuel and electric power to the area has been shut down.Wear rubber gloves and eye protection while cleaning. if skin or eyes come in contact with the agent,flush thoroughly with water.
