INSTALL POLY LATCH U-CHANNEL (continued)
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.
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.
3. After tying the ropes to the main cover, throw the ropes
over the top of the greenhouse and pull the covers into
place.
Use ropes to pull cover over the greenhouse and onto
the frame. ADDITIONAL ASSISTANCE IS REQUIRED.
4. Center cover side-to-side and end-to-end.
IMPORTANT:
To prevent damage to the main cover
during installation, additional personnel and lifts may
be needed.
Verify that you have installed the IR film
according to the markings shown on the film.
5. Once the main cover is in place and centered, begin at
the peak of one end and install the wire spring into the
U-channel to secure the cover.
ATTENTION:
Center the main cover front to back and
side-to-side to ensure that enough cover material is
present to lock into the U-channel. The excess cover
along each side is rolled up when the roll-up side
assemblies are installed.
Photos show installing the spring into the U-channel
on the outside of the greenhouse. The process is the
same for the U-channel attached to the top of the end
rafters.
