Use of the CFD-50
• Check the temperature display daily and make sure the chamber temperature is between 2-8 °C before using.
• Do not overfill the vaccine storage chamber. Leave gaps between vials and boxes to enable cold air circulation
within the chamber. Use trays to organize vaccines and keep boxes from touching the walls or sitting directly on
the floor of the storage chamber.
• Keep vaccine chamber door tightly closed and latched when not in use to maintain the storage temperature inside
• There is no user-adjustable thermostat or sensors in the CFD-50.
• Designate a person to inspect and record the daily operation to ensure the safe use of the CFD-50.
• Only approved vaccines or medical supplies should be stored in the refrigerator. Do not store any foods, beverages,
or flammable, explosive, volatile items (such as alcohol or gasoline) or other dangerous items in CFD-50.
