6. As the spring is install the spring into the U-channel
at the top of the first end rafter, ensure that an even
amount of the cover is exposed and maintained along
the edge of the greenhouse.
NOTE:
The cover material is cut longer/wider than
is required to cover the greenhouse. For easier
anchoring, allow approximately 10" to extend past the
edge of the end rafter as the cover is anchored into
place.
7. Stretch the cover to the other end of the building and
repeat the steps to secure the main cover in the single
U-Channel attached to the top of the remaining end
rafter.
NOTE:
Pull the cover tight as the spring is inserted into
the U-Channel.
8. After the cover is stretched end-to-end and secured
using the wire spring and single U-channel, move to
one side of the frame and repeat the steps to anchor
the main cover to the first side.
Begin at one end of the double poly latch channel and
work toward the other.
Use the upper channel of the
poly latch channel to secure the main cover.
Attach main cover to double poly latch channel.
Install the Inflation Fan Kit
before
installing the second
main cover. Consult the instructions included with the
Inflation Fan Kit to install the kit. Actual components
may differ from example shown.
11. After installing the inflation fan kit, repeat the steps to
install the film for the second main cover.
NOTE:
When installing the second cover film, use the
same upper channel used for the first cover film, and
a second run of spring, which is installed on top of the
first U-channel spring already in the channel.
12. With the second cover film layer installed, test the
operation of the inflation fan kit.
IMPORTANT:
If trimming the excess cover material at
the ends and sides, DO NOT remove too much of the
excess material.
Some excess main cover material (the material that
extends beyond the end rafters and sides) should
remain in place to more easily re-stretch the film if
needed.
13. Continue by installing the roll-up side panels.
INSTALL THE ROLL-UP SIDE ASSEMBLIES
The instructions below describe how to install a single
roll-up sidewall assembly for one side of the frame. The
procedure is repeated for the remaining side.
The procedures to install the roll-up side include the
following:
1. Install roll-up panels.
2. Assemble the roll-up side conduit.
3. Attach the roll-up conduit to the bottom of the roll-up
sides.
4. Assemble the Twist-of-the-Wrist assembly and attach it
to the frame and the roll-up side.
5. Install the Anti-Billow Rope system.
6. Test the operation of the roll-up side.
INSTALL MAIN COVER (continued)
NOTE:
Maintain an even length along the side. The
final stretching of the cover takes place when the last
side is secured.
9. After securing the first side, move to the remaining
side, pull the cover tight, and secure it in place as
previously described.
10. Once the first cover is stretched and secure, install the
inflation fan kit in the desired location and according to
the instructions sent with the kit.
