Drawer Slide Removal/Adjustment
Each drawer slide is independently removable and can be adjusted to different levels. First remove
the drawer per above instructions. Release the locking tabs located on the drawer slide, move the
front tab up and release the tab in the back of the cabinet, by sliding the locking tab towards the
front. See illustration. Unhook the drawer slide assembly from both the front and back shelf
standards by lifting up on the assembly.
To install a drawer slide, reverse the process used to remove the slide. Secure the locking tabs into
position after the drawer slide assembly is in place. Reinstall the drawer.
MAINTENANCE
Periodic Cleaning
Beginning with the initial installation, the interior surfaces of the cabinet should be periodically wiped
down with a solution of warm water and baking soda. This solution will remove any odors from
spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with a
commercial grade of glass cleaner. Caution: Do not use an abrasive or alkaline solution.
All moving parts have been permanently lubricated and will generally require no maintenance.
