Do not operate hood with vertical sash higher than 18” (except during set-up/take-down). 5. If any horizontal sash is open then vertical sash must be completely down. 6. Position horizontal sash in front of you so that it acts as a safety shield. IfHoodAlarmActivates: • It indicates an improper exhaust flow. • Close sashes completely.
