Complete these steps:
1. Move the frame to the location where it will be used if needed.
2. At the drain (low) end of the frame, adjust the adjustable feet to lower that end of the frame as much as possible. Allow enough room between the top of
each foot and the locking nut to make final adjustments and to lock the feet in position. Set a level on the lower frame cross brace and check. Adjust side-
to-side frame position so frame is level. See end frame diagram below.
3. Move to the supply end of the frame and raise that end to achieve the required slope.
4. Level the frame side-to-side after setting end-to-end slope.
5. Recheck the frame slope. Verify that ends are level. Tighten the lock nuts to secure feet.

LEVEL FRAME AND SET SLOPE
Level Frame and Set Slope
To ensure that water flows through and properly drains from the plant channels, a
3" slope toward the drain end
of the system is
required. Frame must also be level from side-to-side when viewed from the end.
ATTENTION:
Example below shows a system setting on a
level finished grade. If finished grade is sloped, make the
necessary adjustments in the calculations to account for any
differences. When slope is properly set, frame should slope 3"
from the supply end down toward the drain end.
