WARNING: DO NOT OVERFILL.
Over-filling may result in personal injury and
damage to the shipper and facility due to liquid
nitrogen spillage.
CAUTION: When filling the unit, avoid liquid nitro-
gen coming in contact with the vacuum plug. Do
not pour the liquid nitrogen on the same side of
the vacuum plug.

Step 5.
Place the unit on a scale and take the tare weight without the canis-
ter but with the neck plug, fill it with liquid nitrogen to the bottom of
the necktube and replace neck plug. After each addition of liquid
nitrogen replace neck plug.
Allow the unit to charge for 2 hours, add liquid nitrogen as needed to
maintain the original liquid level.
Pour out the remaining liquid nitrogen before shipping the unit.
Charging Proccess:
The material to be stored in the refrigerator/ship-
per, as well as the canister should be pre-cooled
before being placed inside the shipper.
The charging of vapor shippers must be carried out by an approved
member of the team.
To assure proper charging, weigh the unit.
The vapor shipper VS2-1 weight should increase by 2.67lbs (1.25Kgs),
VS4-3 weight should increase by 7.66lbs (3.5Kgs).
Be sure there is adequate ventilation.
Adding liquid nitrogen to a warm container may cause splashing
and will generate a significant volume of nitrogen gas.
Note -
Add liquid nitrogen slowly to minimize these effects. Keep your
head clear of the heavy volume of nitrogen vapor that may be
produced. It is extremely cold and could cause personal injury.
