MUST
READ
document included with the shipment.
WARNING:
The anchor assembly is an integral part of
the high tunnel construction. Improper anchoring may
cause high tunnel instability and failure of the structure.
Failing to anchor the high tunnel properly
will void the
manufacturer’s warranty
and may cause serious injury
and damage.
LOCATION
Choosing the proper location is an important step before
you begin to assemble the structure.
The following suggestions and precautions will help you
determine whether your selected location is the best
location.
• Never erect the structure under power lines.
• Identify whether underground cables and pipes are
present
before
preparing the site or anchoring the
structure.
• Location should be away from structures that could
cause snow to drift on or around the building.
• Do not position the high tunnel where large loads
such as snow and ice, large tree branches, or other
overhead obstacles could fall.
SITE
After choosing a location, proper preparation of the site is
essential. Follow the information below.
•
A level site is required
. The site must be level to
properly and safely erect and anchor the structure.
• For sites that are not concrete or gravel, placing wood
blocks or other suitable supports under each rafter leg
helps prevent the pipes from sinking or working into the
site.
• Drainage: Water draining off the structure and from
areas surrounding the site should drain away from the
site to prevent damage to the site, the structure, and
contents of the structure.
WARNING:
The individuals assembling this structure
are responsible for designing and furnishing all
temporary bracing, shoring and support needed during
the assembly process. For safety reasons, those who
are not familiar with recognized construction methods
and techniques must seek the help of a qualified
contractor.
