2. Raise the control module off of the casters. To do
so:
a. Open the access and service doors of the
control module.
b. Using the 6 mm hex wrench or 16 mm open
end wrench, raise the control module at each
of the four corner legs seven (7) half turns
after initial contact with the floor.
During this process one or two leveling feet
may raise off of the floor. This is not a
concern. Even if a foot is lifted off the floor,
only give that leveling leg seven (7) half
turns. This should raise the whole control
module off of the casters seven (7) half turns.
NOTE: Making a mark on the top of
the leg will help you keep track of the
half turns.

3. Check each corner leg to ensure that there is
pressure on the foot and you cannot turn it by
hand.
• If you have correctly given each corner leg
seven (7) half turns you should not be able
to turn the legs by hand.
• If you can turn one of the legs by hand, lower
the control module back onto the casters and
restart this procedure. The goal is to have the
control module weight evenly distributed
across all four leveling feet when it is
properly raised. The module may or may not
be level at this time.
4. Verify the module is level front to back and left to
right by placing a digital level at the following
locations:
a. Inside the access door
b. Inside the service door
c. On the left side inside the access door
A reading on the digital level that is 0.00 +/-
0.30 is considered level.
NOTE: Make sure the digital level is not
resting on any frame welds or debris that
would cause an inaccurate reading. To find
the small circular frame welds, run your
fingertips over the spot where you are
going to place the level.

5. If the module does not meet the 0.00 +/- 0.30
leveling requirement, make further adjustments:
a. Place the digital level inside the access door,
then level the module from left to right:
• Always make your leveling adjustments
to raise the control module (turn the legs
clockwise looking from the top).
• Since the control module frame is very
stiff, adjust the appropriate left or right
leg pair the same amount when leveling
left to right.
• Use small adjustment increments; no more
than one half (½) turn at a time.
• If the leveling adjustment has raised any
of the other leveling legs off the floor, take
