START-UP OF UNIT
Follow the procedures for the initial and consequent operations of the unit.
1.Connect unit to dedicated power supply. Do not put any product in the unit at this time.
2.When the power is initially applied, the audible alarm may sound. This is normal. Press the BUZZER key to silence the alarm. The audible alarm will operate until the temperature monitor bottle sensor goes into the range of 4oC±2oC.
3.Ensure that both monitor bottles have been filled with 10% glycerol as outlined earlier in this manual.
4.The unit has been factory preset to operate at 4oC±1.5oC. There is no need to set the temperature.
5.Proper chamber temperature may take several hours to stabilize at the set point temperature. Once the unit has stabilized, ensure that the monitor bottle temperature agrees with the set point temperature.
6.Turn on the light switch to ensure that the chamber light is properly functional.
7.When you are satisfied that the unit is working correctly, begin slowly placing product into the chamber to minimize the temperature rise.
Handling of containers
Arrange containers so as not to disturb air circulation in the unit. Disturbance of air circulation may cause freezing of contents or increase of temperature.
1. Air intake vent
Avoid the disturbance of air circulation in the unit by containers. Disturbance of air circulation may cause freezing of contents or rise in temperature.
2. Air exhaust vent
Do not block the exhaust air port by putting containers near the exhaust air port. Containers near the exhaust air port may freeze.
3. Load line
This unit determines the range of the containers to ensure proper air circulation. Put containers in range of the label of "Load line" which is attached on both sides inside the unit.
