MAINTENANCE AND CLEANING 

These units require very little maintenance. They should be cleaned periodically to keep them 
running efficiently. Use the cleaning agents and suggestions in the table below for best results.  

The freezers should be defrosted and cleaned whenever ¼ to ½ inch of frost has accumulated inside the 
unit or if the  unit will not maintain proper temperature. Use the procedures in the Defrosting section 
below.
