The model number on your Sno-Block or Spinner Block ice machine is the only way to determine the type of Freon used in the machine.

 

 

All machines with model numbers starting with “B” use Freon 12 –  
except the B-1200-SB – which uses Freon 502

 

All machines with model numbers starting with “MP” use Freon MP39

 

All machines with model numbers starting with “406” use Freon 406A

 

All machines with model numbers starting with “409” use Freon 409A

 

All machines with model numbers starting with “414” use Freon 414B

 

All machines with model numbers staring with “404” use Freon 404A

 

 

It is very important that you keep this manual in a safe place, if your machine requires service it will require the proper Freon.
