Prior to assembly
Please read the instructions carefully before installation. It is important to follow your
local safety regulations and industry standards during installation. Regulations may
include but are not limited to :
Safety helmets, protective eyewear, and clothing
Safety harnesses for all elevated workers
Proper ladder, cage, and safety operation
Check all components and parts before installation. All parts are marked with a part
number, please refer to the parts list to make sure you have all parts.
Choose a day with low or no wind to install, assembly is hard in heavy wind. Do not
make any alterations to the structure. Do not hang any weights on the frame during
installation, including parts. We are not responsible for any damages or injuries caused by
inappropriate installation, unauthorized modifications or extreme weather.
This building is not intended for human occupancy.
It is recommended to tape or add foam/rubber on the frame where joints connect and
where it touches the cover. This will help extend the life span of the cover.
Read the following item list carefully and count the number of items to ensure that all
parts are included prior to setup.

Installation steps
Step 1 : Review the whole structure and choose the proper installation site
Choose a solid flat level ground area to set up the building. Do not install the
building on soft ground, wetland, uneven surfaces, sloped surfaces.
We strongly recommend that you build the structure on a solid foundation such as
cement and use anchor bolts on all base plates.
Be aware of the surrounding area. Do not set up the building near snowdrifts, open
flames or exposed electrical wires. Do not keep heat sources near the fabric cover.
Keep the building surroundings clear at all times
Mark the ground in the final building location with a line showing the positions of
base plates, front doors. All lines should be drawn from center to center of all base
plate tubes. Diagonal line X must be equal to Y.
Base plates: all base plates must be installed firmly with expansion bolts (#6A) on
this step (refer to figure 1).
Parts used in this step :
- (40) Base plate (#6)
- (8) Door column base plate (#7)
- (136) Expansion bolts (#6A)

 Lay down all (20) trusses on the ground as figure 4 when the assembly is all
completed and before moving to next step, and then wrap (#33) around the
sharp points of the joint to avoid friction between the fabric and the interface,
resulting in fabric damage. (Refer to figure 4)

 The whole structure inspection : check all components and trusses to make
sure the whole structure is squared to the base line drawn at the step 1. All
trusses must be set up righted at 90 degree. All purlins must be straight in line.
If any purl ins are not in line with they will need to be corrected before moving
to the next step.
 Now it is the time to secure all bolts and nuts firmed on the structure. But do
not over-tight the bolts, otherwise the tubes might be damaged.

Figure 9
Step 7 : Install the film and roll film system (refer to figure 10)
NOTE : The cover must be installed on a windless day. DO NOT attempt to install the
cover during windy conditions.
 when you are ready to install the roof cover, unpack the cover and position it
parallel to the building frame on one side. The truss connection is wrapped
with adhesive tape (#33) to reduce the friction between the frame and the film.
the cover must be pulled over the top of the truss frame without being snagged
or stressed on any frame members. tighten the film evenly to eliminate
wrinkles and make the film flat and smooth. Do not over-tighten during the
adjustment process, otherwise it will cause unnecessary damage. At this time,
you can install a clip spring (#14A) to fix the film.
 Installation of roll film systems.
A round plug (#30) is put on both ends of the film rolling machine guide tube
(#15), and the guide tube is mounted on the frame with a hex bolt (#26), and it
is required to swing freely. After using a self tapping screw (#27) to connect
the roll film tube (#16), lay it flat on both sides of the frame. The film (#32) is
wound on a roll film tube (#16), and clamped with a pressure film carrier
(#20). The film rolling machine (#18) drives the roll film tube (#16) to be
raised and lowered horizontally and flexibly without jamming.
 Install the eight clip spring (#19) and fasten the braided rope (#31).

After the Installation
Walk around and inspect the tunnel greenhouse periodically to make sure all
components are still firmly secured and the whole shelter is well supported. Check
all bolts and nuts as well as all connection points to make sure they are all in good
position.
We strongly recommend you remove any snow from the roof immediately. Do not
leave any snow load on the roof overnight. Keep 3 feet of clearance on all sides at all
times. Do not allow snow to accumulate and pile up on the sides of the building.
Otherwise the pressure from the sides will push inwards and could lead to a collapse.
