NOTE:
To prevent damage to the end panels,
do not allow the free end of the drive pipe to touch the inside surface of
the end wall. Trim pipe if needed. Drive pipe must turn freely in the band clamps.
17. After installing all sections of drive pipe for the first drop-down panel assembly, verify that the drive pipe is level and
that each conduit splice is secured with a Tek screw (Step 14).
18. Move to the gearbox and test the assembly using the crank handle.
NOTE:
The assembled drive pipe should turn freely throughout the length of the frame. Adjust the band clamps as
needed. Reposition clamps and screws if these prevent smooth operation of the drive pipe.
19. Repeat the procedure to assemble and attach the gearbox and drive pipe
to the other side of the frame.
20. Continue by preparing and attaching the drop-down panels to the frame and drive pipe of both drop-down assemblies.

• Duct tape
• Drop-down panel (Panel ID begins with DD.)
Continue with the steps that follow:
1. Gather the pulleys and the same quantity of FA4652
wood screws and move inside of the high tunnel.
2. Position the first pulley against the ribbon board
approximately 2"-4" from the end rafter where the
gearbox is attached.
NOTE:
Pulley should hang freely from the wood screw.
Do not overtighten the screw. See diagram above.
3. Move to the next rafter and repeat the steps to install another pulley.
Install one pulley for each rafter along each side.
