PROCEDURE

Operational Procedure

• Ensure that the instrument power supply is connected to the main power supply and switch “ON” the mains. The instrument contains a refrigerator on the upper side and a deep freeze on the lower side.
• Place the items required into the refrigerator/ deep freeze after achieving the temperature.
• The temperature in the refrigerator should be 2 to 8°C.

Precautions

• The door shall be closed firmly.
• The door shall be opened for the minimum time.
• Do not overload the fridge with samples.
• Once the temperature is set, do not disturb the Reference temperature and Freezer temperature button.

Temperature Monitoring and Recording

• The minimum and maximum temperature for the refrigerator shall be read and manually recorded on Attachment-I twice daily and the memory reset each time.
• On weekends and holidays, the QC Person will read the minimum and maximum temperatures on the next working day and record the range for the closed days on the temperature log.
