5.0 Removing or replacing a vanity tray

Raise the unit to its fullest extension. In most cases, the vanity tray can be removed by pulling
the tab past the stop. If the stop is too tight, a slotted screw driver may be used to lightly pry
the stop. The vanity can be replaced the same way it was removed.
5.2 Replacing the vanity tray
If replacing the vanity, the rails may need adjustment. Remove the old vanity as described in
5.1. Insert the new vanity.
If the vanity works well and does not slide too hard or easy, no adjustment is necessary. If the
vanity slides too hard or too easily adjustment may be required. If the vanity needs adjustment,
start by loosening (3) screws on the outer rail
with the vanity centered. If the vanity moved too easy, hold the rail slightly closer to the vanity
and retighten the screws. Repeat the process with the other (3) screws on the same rail. If the
vanity is too tight, use the same process but move the rail slightly farther away from the vanity.
