Note: Assembly instructions also apply to models with the suffix C, CR, CU, R or U.

1. Insert the Platform Assembly on the Mounting Cone in the center of the balance.

2. Carefully remove each of the five (5) glass Draft Shield sections from its packing.
You will note that two (2) of these are plain, two (2) contain handles, and the
other is set in a plastic frame. These sections or panels comprise the front and rear,
side doors, and top (respectively) of the Draft Shield. The Draft Shield contains
four (4) upright posts and two (2) cross-members which act as a framework for
insertion of the panels.

3. Install the plain glass panels to form the front and rear of the Draft Shield.

• Select a plain glass panel and insert the bottom edge of the glass in the
recessed slot in front of the balance, as shown.

• As you push the top edge of the glass panel toward the cross-member, reach
inside the top of the framework and depress the small clip located under the
cross-member.

• Press the glass panel into the framework until you feel the glass slip into place.

• Release the clip when the glass panel is fully inserted.

• Repeat these steps to install the other plain glass panel on the opposite side of
the framework.

likewise, you must remove the top door before you remove the side doors.

• Hold and position each door so that the handle is near the front of the balance and
the small notch on the bottom edge of the door is lined up with the tab that protrudes
from the side of the balance housing (shown below).

• Insert the top edge of the glass door into the recessed area under the top cross­member of the Draft Shield framework.

• Slide the notch on the bottom edge over the tab and slip the door in place.

5. The door may now be opened by sliding it toward the back of the balance.

2.3 Selecting the Location

Locate the balance on a firm, steady surface. Avoid locations with excessive air current, vibrations,
heat sources, or rapid temperature changes.

2.4 Leveling the Balance

Before the balance is used, the feet should be adjusted so that the scale is level with the surface.
This will enable accurate weighing. You will see a level bubble indicator in a small round
window on the front of the balance. Level the balance by adjusting the leveling feet so the bubble
is centered in the circle, as seen below.
