INFORMATION ON USE OF OVEN
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.
PREVENTIVE MAINTENANCE
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.
OPERATOR MAINTENANCE
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.
WARNING:
!
Do not work around conveyor with long hair, loose clothing, or dangling jewelry.
Getting caught in the belt could result in serious injury.
DANGER:
!
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.
