Dear Customer: 

Thank you for buying NU-VU

®

 equipment. We think you have purchased one of the best units on 

the market today. 

Every piece of NU-VU

®

 equipment is put through a full electrical test. In addition, NU-VU

®

 ovens 

are  randomly  selected  for  test  baking  to  ensure  you  are  receiving  the  best  product  possible.  The 
interior  of the oven may darken slightly during this testing process. This coloration is normal and 
occurs  in  any  oven  that  has  been  operated  for  a  few  hours.  It  will  not  affect  the  operation, 
durability or warranty of your NU-VU

®

 equipment. 

This  OWNER'S  MANUAL  has  been  put  together  to  give  you  a  good  general  knowledge  of  your

[email protected]. One of our service technicians will be glad to assist you. Please remember to 
supply  the  model  number,  serial  number  and  the  manufacturing  date  code  of  your  NU-VU

®

 

equipment when you contact us.
