Explanation of Optional Liquide Nitrogen Backup system (LN2) The product of -150°C has an automatic cooling auxiliary device as optional. As to an automatic cooling auxiliary device, the inner temperature of a freezer rises, a magnetic valve connected to LN2 cylinder opens when the temperature reaches -130°C, an alarm buzzer goes off and at the same time LN2 sprays from two nozzles into the freezer.
Page 24
Small sow LN2 hose Large sow Hose (3) The temperature under which an automatic cooling auxiliary device operates is set as -130°C. When the inner temperature of a freezer reaches above a setting temperature, a magnetic valve opens and LN2 sprays into a freezer. For installation of the LN2 cylinder, ask an LN2 technician, coursed to the high pressure.

The power of an automatic cooling auxiliary device uses a chargeable battery (lead storage battery). The life of a battery is approx. 3 years. Inquire of a store where a user bought it for replacement. Install it where sufficient ventilation is possible. Ensure to ventilate since there is a risk of hypoxia or gas poisoning due to N2 gas discharge while an automatic cooling auxiliary device is running.
