Section 1 Quick Start-Up

Locate the storage container in a well ventilated area of the laboratory, with

adequate work space available for loading and unloading specimens. Allow

for adequate lid opening clearance.

This unit is designed to operate in the following environmental conditions:

Temperature: 5°C (41°F) to 40°C (104°F)

Humidity: 80% at <31°C, decreasing linearly to 50% at 40°C.

Altitude: < 2,000 meters (6,650 feet)

Warning Whenever working with liquid nitrogen storage equipment in a

closed environment, the use of personal O2detection devices is strongly

recommended. Refer to “Handling Liquid Nitrogen” in the appendix at

the end of this manual. ▲

Section 1

Quick Start-Up

Attach Power Cord

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.
