CONCEPTS

The Impinger® Conveyor Oven produced by Lincoln Foodservice Products, LLC utilizes a revolutionary cooking concept called “AIR IMPINGEMENT.” It provides exceptional baked food product quality in far less time than conventional devices on the market. The “AIR IMPINGEMENT” system directs a high velocity stream of heated air at the food product being baked. This blast effect penetrates the boundary layer of air encircling the product and heats the food more efficiently because the air concentrates heat on the product. Greater heat transfer rates, which result in products baking two to four times faster than conventional means, are possible with “AIR IMPINGEMENT.”

The “AIR IMPINGEMENT” process develops the high velocity air stream with a specially designed fan that draws super-heated air from a heat source (either gas or electric). This air is directed through a plenum chamber to patented “JET FINGERS” which have hundreds of focused jet ports that “impinge” the heated air onto the product surface. The heated air is recycled to the heat source after striking the product, thus reducing energy consumption.

A variable speed conveyor system moves food products through the oven one after another to improve product flow during the cooking process.

The “AIR IMPINGEMENT” process is tolerant enough for sensitive food products and effects proper crisping and even browning of such products as they pass through the oven because air is the medium which heats the food product.

DO NOT ATTEMPT TO OPERATE THE OVEN until connection of utility service and installation has been fully inspected (START-UP CHECKOUT) by an Authorized Service Technician or a Lincoln Foodservice Products, LLC Service Representative. This service is required by Lincoln Foodservice Products, LLC in order to insure the oven(s) is properly installed and in working order. The warranty becomes effective upon verification of proper installation.

The warranty shall not apply if the oven(s) are started up and operated prior to the “START-UP CHECKOUT” being performed by an Authorized Service Technician or a Lincoln Foodservice Products, LLC Service Representative.

If the supply cord appears to be damaged, do not attempt to operate unit. Contact

! WARNING: service agent or qualified technician to repair.

HOW TO OBTAIN SERVICE

If the oven fails to operate, check the circuit breaker to be sure it is turned on (on a gas oven check the manual gas valve to insure it is in the ON position) and check the fuses on the back of the oven to be sure they are good before you call the Authorized Service Agency. The name and phone number of the Authorized Service Agency should be located on the oven or contact the factory at (800) 678-9511 for the name of the nearest agency.

FUNCTIONS

THERMAL CUT-OUT SWITCH FOR CONTROL BOX COMPONENTS

The 3255 unit includes a “safety thermal cut-out switch” for your protection. This safety related device is designed to insure that the 3255 unit will not overheat and damage the unit. In the unlikely event that the 3255 unit would exceed the specified operating temperature range, the “safety thermal cut-out switch” will activate, thus blocking power to the 3255 unit and causing it to turn off.

In order to avoid a hazard due to inadvertent resetting of the thermal cutout, this

! CAUTION: appliance must not be supplied through an external switching device, such as a timer or connected to a circuit that is regularly switched on and off by the utility.
