1.1.
PREPARATION
1.1.1. Check the moisture content of the commodity
using GrainPro Moisture Meter (MM5)
(available for sale from GrainPro, Inc.) to
ensure the MC is at a safe level for
storage/transport.
Recommended Moisture Content:
Coffee – 11.5-12%
Cocoa – 6-7%
Rice – 13-14%
1.1.2. Workers should not wear shoes with spikes
that might cause damage to the TSL.
1.1.3. Ensure that container floor is free of any sharp
objects that may damage the liner.
1.1.4. Place a mat or thick cardboard on the floor as
additional protection for the TSL.
1.1.5. Place the TSL box at the back end of the
container.

1.1.6. Pull the top portion to unfold the TSL, make
sure that the GP logo is facing up for proper
orientation.
2. INSTALLATION USING VACUUM METHOD
2.1.
INSTALLATION
PROCESS
For the vacuum method, a ventilator/fan shall
be used to create negative pressure between the
shipping container and the TSL. The ventilator
should have at least a 1000 m3/minute of flow rate.
2.1.1. Place the ventilator/fan on the top corner of
the container next to its door, this could be on
either left or right side of the container. A
clamp could be used to keep the ventilator in
place.
2.1.2. Fold at least 150cm of the TSL away from the
door opening starting from the zipper. Then
tape the folded section around the perimeter
of the container door.
Note: Make sure not to cover the ventilator
with the folded TSL section to avoid possible
damage.
2.1.3. Turn on the ventilator and wait until the TSL
spreads perfectly on the sides and ceiling of
the container van. A worker can also enter
the TSL to help spread the TSL material and
help correct any folds in the TSL.

2.1.4. Place cardboards on the TSL floor and along
the walls for added protection;
2.1.4.1. For Manual Loading - workers
should not wear shoes with spikes that
might cause damage to the liner.
2.1.5. When stacking bags, make sure to leave at
least 20cm distance between the roof of the
container and top of the stacks to prevent
condensation.
3.1.
USE
OF
DESICCANTS/DRY
BAGS
(REQUIRED)
Desiccants are commonly used to protect
goods against moisture damage. Hygroscopic
commodities, such as cocoa, coffee, and various
nuts and grains are particularly susceptible to mold
and rot when exposed to condensation and
humidity.
3.1.1. Requirement:
a. One-thousand two-hundred (1200) grams or 6 bags of GrainPro Dry Bags per 20-footer.
b. Two-thousand four-hundred (2400) grams or 12 bags of GrainPro Dry Bags per 40-footer.
Note: 1 GrainPro Dry Bag contains 200 grams of calcium chloride and can absorb grams of moisture
3.1.2. Place the GrainPro Dry Bags in perforated bags or sacks to prevent direct contact with commodity.
3.1.3. Cardboards/cartons may be placed on top of the stack (Cardboards/cartons provide increased water
absorption). Then put the desiccants on top of the cardboards/cartons.

READING
Install plastic valve before sealing or zipping the liner. Conduct PDT after sealing. CO2or O2reading
(optional) is taken upon arrival of the container to verify the integrity of the TSL’s hermeticity. After use,
close the plastic valve.
3. SEALING

3.2.1. Plastic valve components:
A. Cap – To open and close the valve
B. Body – Where tube or hose is inserted for
Pressure Decay Test (PDT) and
CO2or O2reading
C. Base – Use for piercing the liner
3.2.2. Dismantle the plastic valve by unscrewing the
base.
3.2.3. Pierce the TSL using the plastic valve.
Piercing is done from the inner side of the
TSL (approximately 20 cm from the zipper).
3.2.4. Screw the plastic valve body. The cap of the
plastic valve should be positioned outside the
loaded TSL. Firmly tightened the body into
the base to prevent leakage.
3.3.
SEALING
OF
2-TRACK
PE
ZIPPER
3.3.1. Remove the ventilator from the container
door. Then remove the tapes and unfold the
excess liner from the door perimeter and let it
loose.

3.3.2. Hold the 2-track zippers together. Align for
proper sealing.
3.3.3. Manually zip a few centimeters enough to
initially engage the zipper slider.
3.3.4. Position the zipper slider on the manually
zipped portion of the zip lock.
3.3.5. For ease of zipping two persons are required.
One person does the zipping and the other
person holds the other end steadily, making
both sections of the zipper in a straight line to
avoid the zipper length being misaligned.
3.3.6. If uneven zipper ends are observed, slightly
stretch both ends of the zipper and redo the
zipping from end to end.
3.3.7. Fold extra liner and tape it against the stack.
Ensure that no liner is stuck in-between
doors.

3.4.
PRESSURE
DECAY
(VACUUM)
TEST
3.4.1. After zipping/sealing of the TSL, perform a
pressure (vacuum) decay test (PDT) to
ensure gas-tightness. With this test a
manometer, vacuum pump and stopwatch
are needed. A digital manometer of a
commercially available or improvised U-tube
manometer can be used to monitor the
pressure.
3.4.2. Connect the manometer hose to the plastic
valve previously installed in the TSL.
3.4.3. Twist the plastic valve cap to open.
3.4.4. Using a vacuum pump with at least 2.3 cubic
meters of suction capacity per minute. Create
at least -250 Pascals (Pa) or -25 millimeters’
water (mm H2O) vacuum inside the TSL by
partially opening a portion of the zipper and
insert the vacuum pump suction port.
3.4.5. For TSL to be considered sufficiently airtight,
the initial vacuum should not decrease by
more than one-half (½) of the final vacuum
(created by the vacuum pump) within five (5)
minutes.
3.4.6. If the PDT test failed, check for holes/tears
and poorly sealed zippers then repeat the
PDT procedures.

3.4.7. After conducting PDT, twist the plastic valve
closed.

READING
To ensure gas-tightness, instead of PDT as an alternative the container with TSL can be checked
using the CO2analyzer or O2analyzer.
3.5.1. The flexible adapter hose is included in the GrainPro Carbon Dioxide Analyzer or the user can find
equivalent flexible hose from local hardware using the specifications as shown:
Inside Diameter 4 mm (0.16 in.)
Length >5 cm (2 in.)
3.5.2. When taking the carbon dioxide or oxygen
reading, connect the flexible adapter hose to
the plastic valve.
3.5.3. Twist the plastic valve cap to open.
3.5.4. Connect the O2or CO2analyzer to the flexible
adapter hose and the reading. Take readings
of CO2and O2using the available analyzer.
Acceptable Values:
For O2analyzer, 3% or below after 15 to 30
days.
For CO2analyzer, 10 to 15% after 15 to 30
days.

3.5.5. Twist the plastic valve cap to close after
taking the readings.
3.6. USING CARBON DIOXIDE ANALYZER FOR MONITORING (WITHOUT CO2FLUSHING) -
OPTIONAL
The GrainPro CO2analyzer uses a non-dispersive infrared radiation (NDIR) sensor for the detection of
carbon dioxide. When a sensor encounters a target gas, voltage signal is generated in proportion to the
gas concentration. This voltage signal is amplified, digitized and displayed on the instrument’s OLED
display.
3.6.1. When taking the carbon dioxide reading,
connect the flexible adapter hose into the
plastic valve.
3.6.2. Using the analyzer, carbon dioxide level can
be checked through the plastic valve with
flexible adapter hose before unloading.
Increased carbon dioxide level indicates
absence of any source of leaks from
punctures, holes or damages. CO2level of
ambient air is 0.04%.
3.6.3. Monitoring of carbon dioxide level is recommended to ensure control of insect infestation. Details of
using CO2analyzer are discussed in the analyzer’s instruction manual.

SAFETY
4.1.1. Carbon dioxide does not support life. It can act as a simple asphyxiant by diluting the concentration
of oxygen in air below the levels necessary to support life. As it is heavier than air it will tend to
concentrate at lower levels.
4.1.2. Avoid breathing gas. Do not get in eyes, on skin, or on clothing. Wear leather safety gloves and
safety shoes when handling cylinders.
4.1.3. Protect cylinders from physical damage. Do not drag, roll, slide or drop. While moving cylinder,
always keep the removable valve cover in place. Never attempt to lift a cylinder by its cap; the cap is
intended solely to protect the valve. When moving cylinders, even for short distances, use a cart
(trolley, hand truck, etc.) designed to transport cylinders.
4.1.4. Never insert an object (e.g., wrench, screwdriver, and pry bar) into cap openings; doing so may
damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted
caps. Slowly open the valve. If the valve is hard to open, discontinue use and contact your supplier.
4.1.5. Close the cylinder valve after each use; keep closed even when empty.
4.1.6. Never apply flame or localized heat directly to any part of the cylinder. High temperatures may
damage the cylinder and could cause the pressure relief device to fail.
