INSTALL MAIN COVER (continued)
12. After installing inflation fan kit, repeat steps to install
second layer of film.
NOTE:
When installing the second film layer, use the
same u-channel used for the first cover film and a
second run of 102198 spring. Install spring over the
first u-channel spring and film layer.
The excess material along the sides is rolled up in the
roll-up side assembly.
13. After installing second film layer, test inflation fan kit.
IMPORTANT:
If trimming the excess cover material at
the ends (not the sides), DO NOT remove too much of
the excess material.
Some excess main cover material (the material that
extends beyond the end rafters) should remain in place
to more easily re-stretch the film if needed.
14. Continue by installing the roll-up side assemblies.
ASSEMBLE ROLL-UP SIDE CONDUIT
Gather parts:
• Pipe 1.315'' x 75'' swaged 17 GA (#131S075)
• Pipe 1.315'' x XX'' plain 17 GA (#131P0XX)
• Tek screws (#FA4482B)
Roll-up side conduit assembly attaches to bottom of roll-up
side panel. Assembly runs length of frame and serves as
the center pipe the roll-up panel wraps around when it is
opened for ventilation.
NOTE:
Number of pipes used in roll-up conduit assembly
varies with length of greenhouse.
Roll-up conduit assemblies consist of multiple sections
of swaged 1.315" pipe at 75" (part #131S075) and one
(1) additional plain 1.315" pipe at a shorter length, where
XX represents remaining length required to complete the
assembly.
Some greenhouses use all 75" swaged pipe for the roll-
up conduit. Last pipe is cut to length after installation.
Complete these steps to assemble the roll-up side conduit.
1. Locate all sections of pipe needed to assemble the roll-
up conduit.
2. Insert swaged end of each pipe into plain end of
another pipe until conduit is assembled.
INSTALL ROLL-UP SIDE ASSEMBLIES
Instructions below describe how to install a single
roll-up sidewall assembly for one side of the frame.
Procedure is repeated for the remaining side.
Steps to install the roll-up side include the following:
1. Assemble the roll-up side conduit.
2. Attach roll-up conduit to bottom of main cover film
along the sides using fabric clips.
3. Assemble the Twist-of-the-Wrist assembly and attach it
to the frame and roll-up side panel.
4. Install anti-billow ropes.
5. Test operation of roll-up side.
3. Secure each pipe joint with an FA4482B Tek screw.
4. Place assembled conduit at base of side where end of
cover film is located.
NOTE:
Wrap duct tape over Tek screws to prevent
damage to film.
5. Repeat steps to assemble remaining conduit.
6. Continue with the next procedure to attach conduit to
roll-up panel.
