Level the Cabinet
DANGER
HAZARD OF ELECTRIC SHOCK
When installing the doors, remember to reconnect all ground and other connection wires.
Failure to follow these instructions will result in death or serious injury.
NOTE: The leveling feet of the cabinet provide a stable base on an uneven floor. They cannot
compensate for a badly sloped surface.
1. Ensure the cabinet is in its intended location. Remove the front and rear doors.
See “Door removal” on page 13 for more information.
NOTE: Before removing the front door, disconnect the ground wires and any other wire
connections that may interfere with the removal of the doors.
2. Insert a Phillips head screwdriver
into the screw above the leveling
foot. Turn the screw to the right to
extend the leveling foot until it makes
firm contact with the floor.
NOTES:
– This method works best with an
empty, or near empty cabinet.
– If the cabinet is loaded with
equipment, a
13 mm open ended wrench can
also be used to lower the leveling
feet.
– Door removal is not required if
using the 13 mm open-ended
wrench.
