Basic safety precautions must be followed to reduce the risk of fire, electrical shock, or injury.
• Connect the CryoWiz™ wall transformer to a 120 VAC or 220 VAC electrical outlet (see “Power
Requirements” section). CONNECTION TO AN INCORRECT VOLTAGE CAN CAUSE SERIOUS DAMAGE
TO THE PRODUCT AND WILL VOID ANY WARRANTY.
• Install the CryoWiz™ where the ambient temperature range is between 0° F and 140° F.
• Do not connect to cryogenic liquid sources lower than 22 PSIG or higher than 35 PSIG.
• Do not install this product in a hazardous environment.
• If product appears damaged in any way, do not use and request service from CONCOA.
• Connect system purge and relief valve outlets to appropriately sized piping to an exterior unobstructed
vent.
• Consult your local LN2 Dealer for detailed handling instructions. Always open valves slowly when being
used.
• Use appropriate protective equipment.
• Always be sure that a cylinder contains the correct gas before connecting it to any manifold.
• Always leak-test any manifold or distribution pipeline before using.
• Always close all cylinder valves before disconnecting cylinders from a manifold.
• Always remove all empty cylinders from a manifold before connecting full cylinders.
• Always check cylinders to be sure the cylinders are full before connecting to a manifold.
• All gas distribution piping systems must meet the appropriate industrial standards for the intended service
and must be thoroughly cleaned before using. For the United States, some applicable safety rules and
precautions are listed below:
