Ceiling Installation (continued)
Level the Ceiling Assembly
1. Position the ceiling panel row 4' to 5' (1219 to 1524 mm) from the floor surface.
2. Use a box level and check the length of the ceiling panel row and make sure that it is straight and level.
a. Adjust turnbuckles to correct any non-straight or out-of-level conditions.
b. Rotate the ceiling assembly as little as possible when adjusting the turnbuckle.
3. With one person standing and observing at the end of the ceiling panel row, do as follows.
a. Rotate the ceiling panel row so that the bottom surface faces downstage.
b. Then, rotate the ceiling panel row so that the bottom surface faces upstage.
c. Any ceiling panel row bowing in either vertical position indicates that further leveling is required.
4. When leveling is complete, lock the turnbuckles into place with nylon cable ties
(contained in the hanger kit hardware bag).
5.
Make sure that all fasteners are tight.
