Emery Thompson CB-350 Countertop Batch Freezer 

Section 8 – CARE & MAINTENANCE 

 
One of the  best  features  of an  Emery Thompson batch freezer is the 
small  amount  of  maintenance  and  the  ease  of  care  required.  The 
materials we use are the best available for their intended purpose and 
designed for maximum longevity. 
 
The outer casing of your machine is all heavy-gauge stainless steel, and 
will only  require  a daily wipe down,  using a mild detergent  and warm 
water. A stainless-steel cleaner/polish can also be used to keep it bright. 

 

Performing  regular  maintenance  on  your  Emery  Thompson  batch 
freezer will keep it running at its peak performance for many years. The 
maintenance required is based on how frequently you run the machine 
and how long you run the machine. It is easiest to think of this as how 
many hours per week (HPW) you run the machine. Example: If you run 
the machine 3 days a week for 4 hours each day, the machine is actually 
running  12  hours  per  week.  The  more  hours  per  week  you  run  your 
machine the more frequently you should perform maintenance. See the 
chart  below  for  routine  maintenance  subjects  and  the  frequency  with 
which they should be performed.
