1. The assembly should be done by authorized professionals, but there are a few notes to be aware of.
   
   a) Most biological refrigerators are built to maintain a temperature to about 2-3 degrees Centigrade and a few hundredths of a percent carbon dioxide level, with an alarm sounding if the temperature or gas varies. When assembled at room temperature, therefore, the alarm goes off. make sure the refrigerator has reached the desired temperature and gas level before placing anything inside.
   
   b) The Alarm buzzers have an ON/OFF switch. Make sure the buzzer is left ON (ie active) when left alone to warn people in case of a problem.

Usage

1. Do not leave the refrigerators open for more than thirty seconds at a time. Doing so usually triggers an alarm. Prolonged opening of the door also burns out the compressor, which is desperately trying to keep the temperature down.
2. Do not place excessive amount of warm compound in the refrigerator all at once. Doing so can increase the temperature of the refrigerator to the point where the alarm sounds.
3. Check to make sure the doors are tightly closed.
4. When not being used, unplug the refrigerator ro prevent burnout of the unit.
   

Maintenance

1. When cleaning the refrigerator, do not use strong detergents, powdered soap, or hot water. These may damage the refrigerator (check manual to be sure). Do not splash water on the outside of the refrigerator; this might lead to a short-circuiting of the unit.
2. To clean up spills, check model-specific manuals.
