Impinger 3255 – Operator Manual

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.
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.
WARNING:
!
If the supply cord appears to be damaged, do not attempt to operate unit. Contact
service agent or qualified technician to repair.
CAUTION:
!
In order to avoid a hazard due to inadvertent resetting of the thermal cutout, this
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.
