The container should be located near the liquid nitrogen supply, allowing
enough space for nitrogen source tank replacement. Arrangements should
be made to collect the condensate, which will form on the transfer hose.
A four foot nitrogen transfer hose with a 1/2" flare fittings is supplied
with Model 7400/7401. A six foot hose is standard with Models
7402/7403, 7404/7405 and 7406/7407. The use of a transfer hose longer
than six feet may degrade system performance.
Caution The flair connection on the ends of the transfer hose does not
require any sealant. Pipe dope or sealing tape may cause contamination of
the liquid fill solenoid, or leaks at the hose connections.
The storage system requires a user supplied low pressure regulated (22
PSIG) liquid nitrogen supply. Anything higher than 22 PSI will degrade
performance of the CryoPlus storage container.
Connect the transfer hose packed with the CryoPlus unit between the low
pressure, liquid outlet of the liquid nitrogen supply tank (22 PSIG) and
the storage container.
After the transfer hose has been connected, open the supply tank valve
and check the connections for leaks.
1. Loosen screw located on the power cord retainer. Spread the retainer.
2. Insert the power cord into the power outlet module. Tighten screw on
the power cord retainer.
3. Fit the power cord/outlet module assembly into the connection on the
unit. Tighten the module screws to secure the cord to the unit.
