INSTALL MAIN COVER
Gather the parts:
• Main covers, inflation fan kit, box cutter or utility knife
• U-channel spring (#102198)
• Ropes long enough to reach over the frame (provided
by customer)
Assembly Procedure
After the poly latch U-channel is attached to the frame,
unpack the main cover and pull into place. Ropes or straps
are typically used to pull the main cover onto and over the
frame.
WARNING:
To prevent damage to the cover and to
prevent serious personal injury, DO NOT attempt to
install the main cover on windy or stormy days.
INSTALL POLY LATCH U-CHANNEL (continued)
3. Continue to attach the U-channel sections to the rafters
(or ribbon board if used) and work toward the other end
of the frame. Cut the last section of U-channel to the
required length so that it is flush with the end wall panel
(if needed).
4. Repeat these steps for the remaining side.
5. After
attaching the U-channel to the sides of the frame,
use Tek screws to attach the single U-channel to the
top edge of the end rafters.
Insert shows the installation of poly latch U-channel on
top of an end rafter. The poly latch U-channel will bend
with the curve of the rafter as it is attached.
6. Continue to attach the U-channel until it has been
installed on the top of
both end rafters
.
The steps that follow describe one way to complete this
process.
ATTENTION: Install the IR film cover first! Examine the
IR film and install with the correct side facing in the
direction indicated on the film.
1. Take the cover film and position it along the base of
one side of the greenhouse.
NOTE:
Unfold the cover and locate the leading edge
The frame shown in the photos that follow differs from
actual frame. Procedure is the same.
Photo shows the cover film in position to pull over the
greenhouse.
2. Along the edge, make small holes in the cover at
evenly spaced intervals and tie rope or straps to the
cover. May not be needed for smaller greenhouses.
NOTE:
The ropes or straps must be long enough to
reach over the top of the building to the other side.
Long buildings require additional ropes to prevent
tearing the main cover when it is pulled into place.
Keep the holes, used to attach the rope or straps, near
the edge of the material and below where the cover will
be secured to the U-channel.
Consult the Spec Sheets for cover identification. The
greenhouse is equipped with double-layer main cover and
an inflation fan kit. One cover is pulled into position and
anchored to the frame, then the inflation kit is installed, and
finally the last main cover is attached.
