Navigation instructions can be found on pages 17-19. Press the “Balance Exhaust Fan” button, and fan will turn on and ramp to full speed. Once fan is on, connect one end of manometer to plenum pressure port (1/8 inch MNPT barb located near grease filter) and take reading. Adjust the max speed as necessary to match the pressure with the corresponding value on the screen (or reference the table below based on your hood size and configuration). For example, for a 36 inch, non-NFPA 101 compliant, external fan – top discharge, inline fan configuration model, to obtain the designed 300 CFM, we need the plenum pressure reading to be 0.25 in. wc. Fan Calibration NOTE Integral fan – front recirculating models shouldn’t have to be calibrated, as these require no added ductwork. Fan calibration is necessary for integral fan – rear discharge and external fan configurations (both inline and fan by others). NOTE To avoid poor hood performance, it is important for the hood to be balanced for the designed CFM. For NFPA 101 compliant models, 500 designed CFM is required. Hood Length (in.)

Recheck nozzles are aimed correctly. Aiming the Nozzles -- NOZZLE AIMING POINT (LEFT)NOZZLE AIMING POINT (RIGHT) 45° TOTAL INCLUDED ANGLE OF ADJUSTMENT IN ANY DIRECTION Operation Unit Pre-Suppression Functions The XRRS functions as a standard ventilation range hood with the added capability to suppress stove top fires. Designed to use over a standard 30 and 36-inch domestic range, the system relies on input from a combination of sensors to control the fan and shutoff power to the stove when the temperature reaches preset points. The fans and lights can be turned on and off using the user interface. The range can also be unlocked via the user interface. A password may be required to unlock (turn on) the range. The range may be automatically locked again after a time limit (default 2 hours) if the hood system was configured for NFPA 101 compliance. To comply with NFPA 101, this time limit cannot exceed 2 hours. If the temperature reaches the cooking detection temperature setpoint (default 115°F), the hood turns the fan on (if not already on) and the fan speed control buttons are disabled. The speed of the fan is no longer controlled via the user, instead the fan is controlled via the hood temperature. If the temperature continues to climb, upon the temperature reaching the high temperature setpoint (default 180°F), the hood will immediately lock (shut off) the range. An alarm will appear on the user interface warning the user of the high temperature. The dry fire/ fault contacts at this point will switch state (see page 13 for terminal blocks and wiring information). If the temperature continues to climb, upon reaching approximately 216°F, the fire suppression system will discharge, dispersing wet chemical on top of the appliance and suppress the fire below. NOTE System must be armed before operating per the instructions on page 16. NOTE Aiming of the hood nozzles is typically performed by factory authorized fire equipment distributor during startup. Do not adjust after startup and arming has been performed. Fire Ready Hood16 Arming the System To arm the range, do the following: 1. Once hood and hood components are installed, wired, and fan is balanced (if necessary), drop the hood into the service position, (instructions on page 20) and turn on all breakers feeding the hood and hood components. 2. Remove the black cover from the fire suppression control board enclosure inside the hood (on left side of hood if looking at the hood front face). 3. With the cylinder pull-pin still installed in the agent tank (mounted beneath the fire suppression board), and 9V battery installed on the fire suppression control board, initiate a diagnostic test by press and release of the “TEST” button (also on the fire suppression board). 7. Remove wing screws that hold the fire suppression control board enclosure in place above the wet chemical tank. Without disconnecting any cables, slide the control board assembly towards the middle of the hood and down so it’s next to the tank, revealing the tank assembly. 8. Check and make sure the solenoid release latch is engaged and holding the release latch up, then remove the pull pin from the agent cylinder and insert the pull pin in its socket on the PCU board. 9. If the push and release of the “RESET” button yielded a green light, leave the pull pin in the CPU. Unlock the range via the user interface.

The test should fail and issue six chirps, indicating that the pull pin has not been removed from the tank. If the result is a lesser number of chirps followed by the series of six chirps, then some item other than the pull pin has failed and the system should be troubleshot before proceeding further (see Diagnostic Failure Codes, page 21). 5. After troubleshooting, re-test until only the 6 chirp diagnostic failure code occurs. 6. Verify that the fuel shut-off is powered (breaker is on) and all burners on the range are off.

The final step for verification is to turn on a range burner, then momentarily push and release the “TEST” button. If there are no failures detected, the fire suppression board will run a shutoff sequence (the alarm will sound for 10 seconds and shut off fuel to the stove followed by a chirp every minute). This allows complete verification of the system function all the way to the fuel shut-off but without the chemical agent dump. If the stove does not shut-off (burner shuts off and begins to cool down), additional troubleshooting is required. 11. Reset the CPU board by pressing the “RESET” button and confirm the green indicator momentarily lights up. 12. Make sure all burners are off, then unlock the range via the user interface. CAUTION Carefully remove the pull pin from the tank, holding the release latch in place, as to not accidentally cause a fire system discharge.

Fire Prevention Tips If you must leave the kitchen when frying food, turn the burner off or remove the pan from the burner until you return. In case of a grease fire: NEVER attempt to move a pan of cooking grease that is already on fire from the kitchen range. NEVER attempt to extinguish a grease fire with water. Instead, alert the other occupants and evacuate. Let the fire suppression system installed in the hood extinguish the range top fire. Wait at least 30 minutes after a cooking fire has been extinguished before approaching your range. Fire Ready Hood22 Service and Maintenance Accessing Internal Components NOTE • All service on the fire suppression system should be performed by authorized equipment distributor. • Do not drop the unit into service position while cooking on the range below. WARNING The hood is heavy. It is recommended to utilize multiple people to drop the hood into the service position; one person to support the hood while the other disengages latches inside, as to prevent the hood from causing injury. ATTENTION La hotte est pesante. Il est recommandé d’utiliser plusieurs personnes pour abaisser la hotte en position d’entretien, une personne supporte la hotte tandis que l’autre dégage les loquets intérieurs pour empêcher la hotte de blesser quelqu’un. 1. Pull down on the two tabs to release and remove the mesh filter from the filter track. Release Tabs 3. With both clamps released, release the safety bolt lever simply by pulling the black handle down. Keep upward pressure on the bottom of the front part of the hood while doing this. After releasing the safety bolt, the hood front will want to drop. Slowly lower the front of the hood until the safety cable is tight. Safety Bolt Lever Safety Cable 2. Behind the mesh filter, in the left and right corner of the plenum are two clamps holding the hood upright in the normal operating position. Press the red button on the bottom side of the clamp to unlock the clamp. Then pull the large red handle down. Release the clamps one at a time. Before releasing the second clamp, push up on the bottom front lip with one hand and use the other to release the second clamp.Step 1 Step 2 4. Now the hood is in its service position. Any service to the fire system and interior components can be done at this time. 5. To put the hood back into operation position, lift the hood back up, and one at a time re-hook the clamps and pull the clamps tight until they lock. Make sure the safety bolt lever is located inside the notch in the hood mounting bracket. Fire Ready Hood 23 Fire System Shut Off Sequence A shut off sequence will cause: 1. 10 second audible alarm 2. Disconnect fuel from range 3. Following the 10 second audible alarm, the unit will issue one chirp every minute to alert the owner that the fire suppression system needs to be serviced. Six items can cause a shut off sequence: 1. Low battery indication has persisted for at least 4.5 hours 2. A test sequence was executed successfully (see Arming the System, page 16) 3. The pull-pin was removed from its socket while in fire detect mode 4. An open circuit was detected on one of the fire suppression temperature sensors while in fire detect mode 5. An open circuit was detected on the solenoid while in fire detect mode 6. Low pressure on tank cylinder detected while in fire detect mode Fire System Detect Mode Upon pressing the “RESET” button on the fire suppression control board (and passing successfully passing all 6 diagnostic tests), the fire suppression control board will display a solid green indicator for two seconds, then the unit will enter into fire detect mode. During fire detect mode the fire suppression control board will silently run all six diagnostic tests. If at any time one of these test fails (with the exception of a low battery), the fire suppression control board will begin a shut off sequence (see above, “Fire System Shut Off Sequence”). Upon a low battery, there will be a short chirp to indicate that the battery needs to be replaced, which occurs every minute. After 4.5 hours of a low battery indication, the unit will enter the shut off sequence. During fire-detect mode, the main unit monitors two sensors to detect high temperature indicating a fire. If a fire is indicated, the fire system control board will issue a fire alarm sequence (see page 22, “Fire Alarm Sequence”). NOTE Powering the fire suppression control board by inserting the battery OR pressing and releasing the “RESET” button will cause the same action. Audible Diagnostic Failure Codes Number of Chirps Corresponding Fire System Component Issue 1 Sensor 1 / Remote Pull 2 Sensor 2 3 Battery Voltage Low 4 Solenoid 5 Low Pressure 6 Pull-Pin Fire System Diagnostics Pressing, then releasing the “TEST” button on the fire system control board will start a diagnostic test, putting the system into “test mode”. This is a way to verify that the entire system is working properly and the fuel shutoff function is working without discharging the fire suppression wet chemical. Upon entering test mode and failing any particular test, a sequence of audible chirps will sound which represent a failure code (as well as a quick flash of the red indicator on the fire suppression control board). If multiple tests fail then you will hear multiple series of beeps with a pause in between each to identify multiple failure codes. Upon failing any part of the test, the control board will revert to a slowly flashing red indicator. If all six tests pass, the unit will enter a shut off sequence. (See next section, Fire System Shut Off Sequence). NOTE The same tests that are performed after pressing and releasing the “RESET” button are performed when pressing and releasing the “TEST” button. Fire Ready Hood24 Fire Alarm Sequence A fire alarm sequence will only occur upon the detection of extremely high hood temperatures (approximately 216°), or when the remote pull station is pulled (if provided). The fire alarm sequence causes: 1. Audible alarm 2. Fire system (wet chemical) discharge 3. Fuel shut off to disconnect fuel to the cooking appliance (if not already shut off due to a high temperature alarm). After Actuation 1. Shut off power to range (via building breaker). 2. Clean up all wet chemical using soap and warm water with a sponge. Do not use vacuum cleaner. 3. Carefully drop the hood into the service position, remove the fire suppression control board enclosure cover, and remove the battery from the fire suppression control board. 4. Disconnect the tank cylinder release valve terminal wire connections from the fire suppression control board. 5. Remove the extinguisher cylinder assembly from the enclosure based by loosening the cylinder band. 6. Unscrew and remove the extinguisher cylinder manifold / siphon tube assembly from the extinguisher cylinder. Pour out any leftover wet chemical in the cylinder. 7. Refill extinguisher cylinder with 4.9 lbs. of wet chemical agent (part of recharge kit). NOTE The fire alarm sequence can only occur when the fire suppression control board is running in fire detect mode. NOTE To mute the audible alarm, place the hood into service position, and press “RESET” button on fire suppression control board. NOTE A complete system inspection and servicing must be done immediately following a kitchen range top fire. Consult an authorized fire equipment company for service or proper procedure. NOTE All service on the fire suppression system after actuation should be performed by authorized equipment distributor. CAUTION Before replacing the wet chemical, the tank, release valve assembly, it is recommended to wear approved type of eye protection and rubber gloves. 8. Flush out existing distribution assembly water to remove residual wet chemical and blow dry. 9. Replace the extinguisher cylinder manifold O-ring and reinstall manifold / siphon tube assembly into the extinguisher cylinder (part of recharge kit). 10. Connect a nitrogen supply line to the ¼ inch male quick connect fitting and pressurize to 100 PSI. 11. Reinstall the extinguisher cylinder assembly in the enclosure base. 12. Refer to the “Arming the System” section on page 16 to reactivate the system. CAUTION Do not use extinguisher cylinder gauge to determine when the intended charge pressure has been reached. AVERTISSEMENT Ne pas utiliser le manomètre du cylindre extincteur pour déterminer le moment où a été atteint la pression de charge prévue. NOTE Upon performing the fire system diagnostic test, additional components may need to be replaced as a result of the high temperatures and flames that occurred during the fire. Replace these parts as necessary (see “Parts” on page 24). Fire Ready Hood 25 Routine Maintenance Monthly Annually Every 10 Years Cleaning Yes Yes — Suppression Nozzles Inspect Inspect — Temperature Sensors Inspect Inspect — Extinguisher Tank Inspect Recertify Replace Replace hood lights, sensors, and other components as necessary. On front recirculation models, replace the charcoal filter routinely (as needed) to help catch cooking odor molecules when recirculating air back into the space. To clean hood, wipe grease from exposed metal surfaces on the hood interior using a clean, dry cloth. Stainless steel hood exterior surfaces should be cleaned with a mild detergent then polished with a high grade stainless steel polish to preserve the original luster. Routinely remove metal mesh grease filter from the hood and clean using hot water and mild detergent. NOTE Never use abrasive cleaners or chemicals on hood surfaces. Never use chlorine based cleaners or iron wool pads to clean the hood. They may scratch or mar the material, allowing pitting and rust to form. Always rub with the grain of the stainless when cleaning.
