STAINLESS STEEL BAFFLE FILTERS

About Your New Filters
Stainless Steel Baffle Filters do not need linings or mesh inside of the filters and are completely constructed out of stainless steel. The stainless steel construction allows them to be used again and again after being cleaned or going through the dishwasher.

How do Permanent Filters work?
They function by forcing the grease filled air to quickly and continuously change direction as it passes through the filter. The grease is unable to change direction as fast as the air carrying them, they end up getting caught on the metal blades and then trapped into the filter tray.
These filters are both efficient and require less maintenance.

MAINTENANCE

Care and Cleaning

The metal baffles channel grease released by foods on the cook top into the drip trays. The baffles also help prevent flaming foods on the cook top from damaging the inside of the hood. For this reason, the baffles must ALWAYS be in place when the hood is used. The grease baffles and drip trays should be cleaned once a month, or as needed.

To clean the grease baffles and drip trays:
Drain and wipe all excess grease with a dry paper towel, Soak them and then swish them around in hot water and detergent. Don't use ammonia or ammonia products because they will darken the metal. Do not use abrasives or oven cleaners. Rinse, shake and let them dry before replacing. They may also be cleaned in an automatic dishwasher.

To remove:
Grasp the filter handles and pull them up, forward and out. Grasp the drip tray and carefully lift it up and out of the hood track.

To replace the drip trays:

1. Place and seat the drip tray into the hood rack.
2. Slide them left and right until all trays are side-by-side in place in the track
