1. PRODUCT DESCRIPTION
Greenhouse “MAGNOLIA” is designed to create an optimal microclimate for
growing vegetables, flowers and seedlings in the smallholding. The framework parts
are made of steel galvanized profile tube with a square cross-section of 25 x 25 mm
The greenhouse is intended to be covered with cellular polycarbonate.
The end-faces and the framework intermediate arches are connected by six
longitudinal stringers. To exclude the slope of the framework end-faces under wind
loads, end-face diagonal ties are provided.
Elements necessary for assembly (self-tapping screws, bolts, nuts, fittings) are
supplied in boxes. For fixing the cellular polycarbonate on the roof of the greenhouse,
galvanized steel tie bands with a tensioning system are provided. Fixing the
polycarbonate to the end-faces and side walls is carried out with self-tapping screws
through special elastic thermal washers.

Warning!
To mount the grousers it is
necessary preliminary to
unscrew the self-tapping
screws #37 of the end-face
posts, connecting the post
and the bottom crossbar of
the end-face,
install the grouser, then to
screw the self-tapping
screws back.

6 CUTTING OUT AND INSTALLATION OF CELLULAR POLYCARBONATE (CP) TO THE
END-FACES
Warning! When installing the CP, it is important that the CP cellular lines are
vertical (from top to bottom). Be sure to remove the wrapping film from both sides of
the sheet. The front (facing the sun) side of the cellular polycarbonate is marked by the
manufacturer with a special symbol (color stripe. sticker or other).
The required quantity of sheets and cutting scheme for cellular polycarbonate of
2100x6000mm for greenhouses NOVA with length 4 - 6 - 8 - 10 m are shown at the
end of the instructions (Annex 1).
6.2. Put the part “A” of CP to the end-face door by aligning the bottom edge of CP
along the bottom lintel of the end-face. Fasten part 1 with self-tapping screws #38
through thermal washers #39 according to the scheme of polycarbonate fastening (see
below).
6.3. Put the part “B” of CP to the left-hand side of the end-face, and the part “C”
- to the right-hand side of the end-face, having aligned the bottom edge of CP on the
bottom lintel of the end-face. Fasten the parts “B” and “C” with self-tapping screws
#38 through the thermal washers #39 according to the scheme of polycarbonate
fastening (see further).
6.4. Mount polycarbonate on the second end-face in the same way.
6.5. Cut off the protruding edges of CP along the outer edge of the framework
6.6. Cut through the slits for the doors and air gates in the “A” parts.

Layout of polycarbonate sheets on the end-face
Scheme of polycarbonate fastening on the end-faces,
There are 48 self-tapping screws and thermal washers per one end-face
6.7. Using self-tapping screws #37 secure the door holder # 41 to the right
middle end-face lintel and fix the mating hinge of the door so that the door holder
secures the door in the open position.
6.8. Insert the hand lever from the kit #40 into the Ø12 holes on the doors,
preliminary drilling the corresponding holes in the polycarbonate.
On the back side put on the locking point and the shield, and fasten them with
screws and nuts M5 from the kit #40:
6.9. Mount hand levers of air-gates in the same way.

7. Mounting of Cellular polycarbonate (CP) on the roof
Warning! When installing the CP, it is important that the CP cellular lines be on the roof
along the arcs, and on the side walls - vertically.
The parts "D" with the size of 2100x3250mm are used for mounting.
7.1. Start the installation of the CP sheets on the roof from the end-faces. Place the
CP on the roof so that the sheet protrudes (hangs over) about 5 cm beyond the edge
of the end-face over the door. The side edges of the CP (with open cellular) should not
protrude over the edge of the side wall, so the CP will need to be trimmed after
installation.
7.2. Press the CP sheet on one side of the arc (1) with tie band #31 and secure the
end of the tie band with a self-tapping screw #38 at the arc through the angle piece #
29:
7.3. Bend the tie band at the place where the two holes are punched 5 cm apart
each other (2) so that the holes are opposite each other. Insert the screw #35 with two
washers #33 into the holes and tighten the nut #36. Tighten the tie band by hand,
press down by CP and fix the second end to the opposite side of arc (3) with self-tapping
screw #38.
7.4. Center the tie band along the arc. Tighten the tie band by screw #35. The tie
band should hold the sheet tight against the arch.
7.5. Mount with overlapping joint the intermediate CP sheet (for greenhouse
length 6 m and more) to the previous sheet and tighten with the tie bands.
If necessary, cut off the protruding polycarbonate along the edge of the side wall.
7.6. After installing all the sheets, check the correct positioning of the CP sheets,
the parallelism of the cellular lines in relation to the arcs of the arches, the position and
the tension of the tie bands.
At least once a year, check the tension of the tie bands.

8. MOUNTING OF CELLULAR POLYCARBONATE (CP) ON THE SIDE WALLS
The parts "E" with the size of 2100x1650mm are used for mounting.
8.1. Start mounting the CP sheets to the sides from the end-faces. Place the CP
sheet to the side of the framework, aligning the top of the CP to the center of angle
piece #29 and the side edge of the CP to the end post.
8.2. Using self-tapping screws #38 through the thermal washers #39 fasten the CP
to the side posts and longitudinal stringers according to the scheme of fixing the
polycarbonate on the side walls.
8.3. Similarly, mount the remaining side sheets of CP, overlapping with the
previous ones, as well as on the opposite wall.
Scheme of polycarbonate fastening on the side walls.
Attention! CP sheet is not attached to the posts of the end-faces!
(vertical joint of polycarbonate is fixed with an angle piece)

- 19 -
9. INSTALLATION OF EXTERIOR ANGLE PIECES
9.1. Using #38 self-tapping screws mount four angle pieces #30 (90°, 1600 mm) on
the vertical corners of the framework, 8 self-tapping screws per angle piece, thus
closing the vertical corner joints of polycarbonate:
9.2. Using # 38 self-tapping screws mount four angle pieces #29 (120°, 2025 mm)
to the joint polycarbonate roof and wall, over the tie bands, 4 self-tapping screws per
one angle piece, thus closing the horizontal corner joints of polycarbonate.

10. Greenhouse installation
10.1. Before starting operations, the site on which the greenhouse will be installed
should be carefully leveled.
10.2. Dig holes or trenches of sufficient length and width under the legs equipped
with grousers.
10.3. Position the assembled greenhouse so that the bottom longitudinal stringers
are on the same level with the ground and the legs are deepened into the ground.
10.4. Backfill the legs with earth and compact them down.
When lowering the greenhouse into the trench or holes, make sure that there is no
longitudinal misalignment of the framework and that the tie bands are not displaced
from the arches. After compacting the ground, make sure that the tie bands are not
offset to the sides and are along the arches. Correct if necessary.
A wooden, concrete or brick foundation can be used to strengthen the greenhouse.
Attention!
One of the features of the greenhouse is wind resistance. It is forbidden to leave the
greenhouse unfasten on the ground. Additional fastening to the ground with
improvised materials (rod, rebar, etc.) is necessary if the greenhouse is installed in
windy area.
Do not install the greenhouse in close proximity (less than 2 meters) to buildings, safety
enclosure, fences.
The area on which the greenhouse is installed should be flat, without significant
differences in the level of the ground.
