INSTALL PVC CONDUIT (CONTINUED)
Shelter shown above may be a different model and length. Photo used for
illustration purposes only.
NOTE:
Maintain an even distance between the end rafter and the PVC
conduit as the strap is tightened.
Also check that the bonnet portion of the main cover overlaps the end
rafters evenly at both ends
before
stretching the cover. Check this
periodically as the cover is stretched.
If the side straps are too tight and prevent the cover from stretching end-to-
end, loosen but do not remove the straps as needed and continue.
Once the strap is tight at one end, cut it to length (if needed) and tie it to the
13.
other leg of the same end rafter.
At each end of the stretch hem strap, drive a Tek screw through the strap
14.
and into the back side of the rafter to secure the strap to the rafter. This
helps keep the strap tight and in position.
Return to the other end of the frame and tighten that strapping (if needed)
15.
to complete the stretching of the main cover from end-to-end. Secure the
strap using a Tek screw at each end (Step 14).
Continue by tightening the side ratchets.
16.
Beginning at either end of the cover, tighten the strap. The strapping will
12.
pull against the strapping installed at the other end of the frame.
TIGHTEN THE SIDE RATCHETS
Verify that the cover is in the desired position and centered on the frame.
(Loosen and reposition if needed.) Continue with these steps to tighten the side
ratchets.
Move to the side ratchets attached to each leg of one rafter. Begin at an
1.
inside rafter near the center of the frame.
With an assistant at one side ratchet and someone at the other side ratchet
2.
on the same rafter
, tighten the ratchets to secure the cover.
Tightening the ratchets at the same time on the same rafter helps keep the
cover centered and results in a more uniform appearance.
Move to another rafter and repeat the steps to tighten the side ratchets
3.
attached to that rafter.
NOTE:
If the strap builds up in the ratchet, loosen the ratchet, remove some
of the strap, and retighten.
After all side ratchets (QH1065) are tight, position someone at each ratchet
4.
attached to the end rafter where the bonnet straps of the cover were
previously inserted.
Tighten the end ratchets to secure the bonnet portion of the main cover.
5.
Move to the other end of the building and secure the bonnet at that end.
