As explained in “Concepts,” the Impinger® oven functions by directing high velocity streams of heated air directly 
on the food products.  Because air is the heat source, it is effective even on sensitive foods.  Compared to 
conventional ovens and even convection ovens, the cooking time of products in the Impinger® Conveyor ovens can 
be as much as two (2) to four (4) times faster.  Several factors may affect the cooking time of any special product 
such as: 1) oven temperature setting, 2) conveyor speed, 3) position of columnating plate in oven, and 4) 
adjustments of the 2 baffles on the conveyor openings. 
 
We encourage you to experiment with the oven by trying different temperature settings and belt speeds.  Also, try 
to control the cooking of the product by re-arranging the optional columnating plates. 

 

 
Although this oven has been designed to be as trouble-free as possible, periodic preventive maintenance is 
essential to maintain peak performance.  It is necessary to keep the motors, fans, and electronic controls free of 
dirt, dust and debris to insure proper cooling.  Overheating is detrimental to the life of all components mentioned.  
The periodic intervals for preventive cleaning may very greatly depending on the environment in which the oven is 
operating.  You must discuss the need for preventive maintenance with your Authorized Service Agency to 
establish a proper program.  If there are any questions that the service agency cannot answer, please contact 
Lincoln Foodservice Technical Service Department at (800) 678-9511.

 

 

 
 
 
 

 

 
To maintain maximum efficiency of the oven, it is necessary to keep it clean, all ventilation louvers on the oven 
must be cleaned regularly.  Oven use and type of product will actually determine the frequency of cleaning.  The 
conveyor drive chain should be checked during the weekly cleaning cycle to see if it has become loose.  Loose 
chain operation will DAMAGE the conveyor drive motor. 
 
If the oven fails to operate, check the circuit breaker to be sure it is turned on.  Also, check the fuses on the control 
panel to be sure that they are good before you call the Authorized Service Agency.  The name and phone number 
of the Authorized Service Agency should be located at the bottom of the data plate. 
 
 

 

 

Do not work around conveyor with long hair, loose clothing, or dangling jewelry.  
Getting caught in the belt could result in serious injury. 

 

 

Disconnect power supply before servicing or cleaning this unit.  Safeguard power so it 
cannot be accidentally restored.  Failure to do so could result in serious injury.  There 
is more than one power supply connection point when ovens are stacked, so make 
sure that all switches are in “OFF” position before cleaning or maintenance.
