INSPECTING THE DISCHARGE NOZZLES
All discharge nozzles have blow-off nozzle caps installed. Remove nozzle caps by carefully pulling them off.
Inspect the nozzle orifice and caps for grease build-up and/or if so rinse with hot water until build-up is no longer
present.
If clogging is suspected, remove the discharge nozzle with a 7/16” wrench
o Flush with hot water until the water flows freely through the discharge nozzle
o If this cannot be achieved, replace the nozzle since it can substantially compromise the fire

water.
Reinstall the tank by reversing the steps to remove the tank.
Remove the hood from maintenance mode and return to normal operation mode.
CLEANING THE HOOD

warm water. Taking care not to splash water onto the electrical system, as this could damage the hood.
The grease entrapment filter, grease tray and front discharge grille (on recirculating hoods only), should be cleaned
by running through the dishwasher or washing them in the sink with mild detergent and warm water
The carbon filter cannot be washed and should be replaced periodically as needed. About every 2-3 months
depending on the amount of use.
WARNING: If grease build-up on the actuation cable is not kept to a minimum, the actuation
cable could become sti
and will not discharge the suppressant in the event of a fire.
