1.Be sure to support the rail cover when cleaning. Otherwise, the rail cover could close suddenly and cause injury.

2.Metal edges can cause cuts. Use care and wear protective gloves when cleaning.

3. Exterior

Wipe the exterior occasionally with a clean, soft cloth. Use a damp cloth containing a neutral cleaner to wipe off oil or dirt build up.

4. Cabinet Interior

Spills and splashes should be wiped up promptly to avoid unpleasant odors. The cabinet interior should be cleaned periodically with a mild soap or detergent and warm water.

5. Door/Drawer Gaskets

6.Shelves (if applicable) Remove and clean regularly.

7.Drawers (if applicable)

The drawers can be removed for cleaning either individually or as an entire assembly.

To remove an individual drawer, first remove all food product from the drawer. Pull the drawer out to its fully extended position and lift up on the handle to disengage the drawer. Before removing the drawer, carefully support the rear and front of the drawer and then slowly remove it from the cabinet.

To remove the drawer frame assembly, first remove the drawers and then remove

the fasteners in the thermal break and in the rear of the cabinet. Carefully slide the frame out of the cabinet, making sure not to damage the thermal break. Reinstall in the reverse order, making sure not to overtighten the screws in the thermal break.

To remove the drawer slide (center slide containing rollers) for cleaning, rotate the top of the slide away from the frame while the slide is completely inside the cabinet. Drawer slides do not require lubrication, but slides should be kept clean and free of food.

Note: Drawer slides are dishwasher safe.
