ABOUT YOUR QBT 

The NU-VU

®

  QBT  is an electrically powered and operated commercial baking/cooking appliance. It does not 

require exterior venting under normal circumstances; however, hood and venting requirements vary from country 
to country, state to state, and even from locality to locality. For this reason, NU-VU

®

 cannot give specific detailed 

information regarding your individual application. Your local building inspector, licensed contractor, or installer is 
best qualified to determine your specific needs. 

The oven section of the QBT features our patented V-AIR

®

 air movement system. A top-mounted blower moves 

the air down through the side walls to be heated, then out through specially designed hole patterns to provide even 
heat distribution throughout the oven. Your product is baked evenly from top to bottom, side to side, front to back 
without turning pans. You can load the oven completely with pans having the same product, bake, and remove the 
entire load at the same time. The bake is uniform because each shelf now receives essentially the same air pattern. 

It is constructed of stainless steel both inside and out. The front and back frames are cut from single sheets of 
stainless steel. Components such as temperature and humidity controls, timers, switches, motors, heating elements, 
and others are thoroughly tested before shipment. Ongoing research and development projects are used to 
introduce the latest and most dependable components. 

The NU-VU

®

 QBT is designed for: 

 

• 

Automatic pan positioning 

• 

Dependability 

 

• 

Rapid and even baking 

• 

Low energy consumption 

 

• 

Easy cleaning 

• 

Low maintenance 

 

• 

Simple operation 

• 

Rapid servicing 

The  AUTOFILL  option eliminates the manually filled water pan in the proofer, but requires connection to a 
pressurized potable water supply. The immersible element in the AUTOFILL water pan distributes humidity 
evenly throughout the proofer compartment to provide the controlled humidity necessary for proper proofing 
action. 

 

IMPORTANT: This appliance is not intended for use by persons (including children) 
with reduced physical, sensory or mental capabilities, or lack of experience and 
knowledge, unless they have been given supervision or instruction concerning use of 
the appliance by a person responsible for their safety. 
 
Children should be supervised to ensure that they do not play with the appliance.
