5. INSTALLATION
5.1. SITE SELECTION
5.1.1. In selecting a site, look for:
a. G-HF Cocoon is designed for both
indoor and outdoor installations.
b. A smooth area away from standing or
running water.
c. Ensure that the site is protected from
stray animals and from theft.
d. Shade (otherwise under a
GrainShade™) to minimize
temperature differences.
5.1.2. Prepare the selected site by clearing away all sharp objects (stones, broken glass, nails, etc.)
that may puncture the G-HF Cocoon. Sufficient space to accommodate the G-HF Cocoon and
an inspection path around (at least 50 cm each side).
5.1.3. If ground will be used as flooring, put a
layer (5cm) of fine sand (or any equivalent)
on top of the soil as ground foundation.
5.1.4. During loading, make sure that workers do not wear shoes with spikes that may damage the
G-HF Cocoon. Preferably, choose a site that offers ease in loading/unloading, away from
crowded areas and rubbish. For indoor installation, clean the area to remove sharp objects.
5.2. LOADING
5.2.1. Check the moisture content of the
commodity to ensure the MC is at a safe
level.
5.2.2. Loading the bottom section:
a. Unfold the bottom section of the
Cocoon and lay it out on the prepared
site.
b. Start piling the sacks on the bottom
section.
c. Put down the first four bags each in
every corner of the G-HF Cocoon.
d. Make sure that the bottom section is
stretched by pulling the corners with
the bags. Stretching will reduce the risk
of rodent damage.

MA2021TDB1199-19
5.2.3. Required stack height:
a. Load the first layer of sacks in one
direction.
b. Continue adding layers in an
interlocking manner (crisscross), i.e.
one layer on the top of the previous
layer.
c. Stacked sacks to the corresponding
height.
5.2.4. Providing a cavity/canal for CO2flushing:
a. Create a cavity/canal about 1-2 layers
(20cm wide-up) aligned with the inlet
port to the center of the stack.
b. This will help facilitate CO2flushing and
avoid dry ice build-up that may cause
the G-HF Cocoon liner becomes brittle
that will eventually crack/explode.
5.2.5. Mechanical loading of bagged commodity (optional for larger G-HF Cocoon):
a. Stacking of grains involves diverse equipment such as conveyor, forklift or crane.
b. Operations provide continuous stacking without delays especially for outdoor installation.
Conveyor
Forklift
Crane
5.2.6. The top layer:
a. Continue piling the sacks until the
desired G-HF Cocoon height is
reached.
b. Once you have reached the required
stacking height, provide one line of
sacks in the middle along the longitude
of the stack.
c. This creates a crest that will keep
rainwater from accumulating on the top
of the G-HF Cocoon.
5.3. POSITIONING THE TOP SECTION
5.3.1. There are several ways to place the top section:
a. By rolling.
b. By using forklift or conveyor.
Rolling method
Use of forklift
Use of conveyor
5.3.2. Unfold the top section over the stack, making sure that top and bottom section arrows are
aligned and tension straps are outside.

5.3.3. One pair of arrows is painted green. Match these arrows for correct front and back orientation
of the Cocoon.
5.3.4. Pull the sides all the way down over the stack.
5.3.5. Do not use tensions straps to pull or carry the top section.
5.4. USE OF DESICCANT (CALCIUM CHLORIDE, CaCl2) –(Recommended)
5.4.1. Required dosage of Calcium Chloride, CalCl2.
5.4.2. Place the packed desiccant (Calcium Chloride, CaCl2), at the middle-top portion of the
bags inside the SVC G-HF before Zipping.
5.4.3. If it will be in six(6) months of storage, spread-out the packed desiccant (Calcium Chloride,
CaCl2) at the top portion of the bags inside the SVC G-HF before Zipping.

5.5. ZIPPING
5.5.1. Preparing to zip:
a. Insert one hand inside the inverted
pocket and engage the zipper track for
the top and bottom liners by pressing
the zipper against the other hand.
b. Manually close the zipper track to a
length of 10cm before using the zipper
pull
NOTE:
▪There are zipper pulls that zip to the right for right-handed users [marked with “RIGHT”]
and zipper pulls that zip to the left for left-handed users [marked with “LEFT”], select the
direction with which you are most comfortable.
5.5.2. Engaging the zipper pull:
a. Open the zipper mechanism by moving
the black plastic handle projecting from
the large wheel away from the flexible
pulling loop.
