GENERAL INFORMATION

The instructions that follow are intended as a guide for preparing for the installation of the Impinger Conveyor oven.
First and foremost, each crate should be examined before signing the Bill of Lading to report any visible damage caused during shipment and account for the number of crates.
IF THERE IS APPARENT DAMAGE: the United States and Canada – arrangements should be made to file a claim against the carrier. As Interstate Commerce Regulations require that the claim must be initiated by the consignee. All shipments to other countries – freight terms will be developed and extended on an individual basis.
Proper and secure storage facilities should be arranged for the oven(s) if necessary to protect it from outdoor or damp conditions at all times before installation.

SPACING

The oven must have 6 inches (152mm) of clearance from combustible surfaces. In case other equipment is located on the right side of the oven, a minimum clearance of 24 inches (609mm) is required from that equipment.
FOR ALL OVENS: A 24-inch (609mm) clearance at the rear of the oven must be obtainable for service access.

ELECTRICAL GROUNDING INSTRUCTIONS

WARNING
DOMESTIC:
As it pertains to domestic model units, this appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.
WARNING
INT’L (CE):
This appliance must be properly grounded at time of installation. Failure to ensure that this equipment is properly grounded can result in electrocution, dismemberment, or fatal injury.
WARNING:
If the supply cord appears to be damaged, do not attempt to operate the unit. Contact a service agent or qualified electrician to repair.

ELECTRICAL CODE REFERENCE

IN USA
When installed, this appliance must be electrically grounded and its installation must comply with the
National Electric Code, ANSI-NFPA 70, latest version, the manufacturer’s installation instructions, and applicable municipal building codes.
IN CANADA
All electrical connections are to be made in accordance with CSA C22.1 – Canadian Electrical Code Part 1 and/or local codes.
ALL OTHER COUNTRIES
Local electrical codes will prevail.

1. Strain relief is provided with each oven. International Dealer/Distributors provide applicable power cord/plug for each customer.
2. All pole disconnection switch 3mm open contact distance.
3. To prevent electrical shock, an equal potential bonding ground lug is provided in the back. This allows the oven to be connected to an external bonding system.
4. If used as a double stack and each oven has its own disconnection switch, all switches should be close together.

VENTILATION

Local codes prevail. These are the “authority having jurisdiction” as stated by the NATIONAL FIRE
PROTECTION ASSOCIATION, INC. in NFPA 96, latest edition.
For standard ovens, a ventilation hood is required to remove heat and cooking odors. Alternatively, optional electric “ventless” models are available which incorporate a catalyst to limit the emission of grease-laden air to below 5mg/m³. Ventless ovens have been tested in accordance with UL710B & EPA-202 and are listed by UL in the KNLZ category. Ventless ovens should only be used for reheating purposes and should not be used to cook raw animal proteins, doing so may cause the appliance to exceed allowable grease-laden air limits and/or cause damage to the catalyst. Ventless oven models can be identified by the “-V-” suffix as part of their model number, refer to the spec sheet for more details.
When permitted by local code(s) and used with appropriate food products, Lincoln “ventless” ovens are not required to be installed under a ventilation hood.
Lincoln 2500 digital countertop ventless ovens equipped with a catalyst are approved for ventless operation while single or double-stacked only.

ASSEMBLY INSTRUCTIONS

INSTALL LEGS AS SHOWN

CAUTION:
Legs MUST be installed to ensure proper operation! Failure to do so will result in damage to the unit and denied warranty claims.

CAUTION:
Oven must be operated on an approved base only. When utilizing a doublestack configuration of ovens, the bottom unit must always be mounted on the legs provided.
CAUTION:
Before applying power to the oven, check to ensure that the finger assemblies and air duct panels (upper and lower) are properly seated and have not become dislodged during shipment.

STACKING INSTRUCTIONS

FOR SINGLE AND DOUBLE-STACK UNITS

NOTE:

When stacking ovens, be sure to remove the bottom flue cap from the top oven.

CAUTION:

Ovens with a Beveled front panel [Series 1300 analog ovens and Model # 2500 oven] should always be the bottom oven of a double-stack of Lincoln ovens. Models 2501 and 2502 [no bevel] should always be stacked on top of other Lincoln DCTI models [Series 1300 analog and Model 2500 Dual Voltage ovens]. Incorrect stacking arrangement may damage both ovens. Please consult with Lincoln Customer Service or our Technical Support team if unsure about stacking configuration.

NOTE:
When utilizing a double-stack configuration, stack the ovens so that the small “foot” on the top oven fits into the “indentation” on the top of the bottom oven.

CLEANING INSTRUCTIONS / OPERATOR MAINTENANCE

WARNING:
Disconnect the power supply before servicing or cleaning this oven. Safeguard power so it cannot be accidentally restored. Failure to do so could result in dismemberment, electrocution, or fatal injury.
The Lincoln Countertop Impinger Oven contains electrical components. Before cleaning the oven, switch off and disconnect the oven from the electrical supply.
No electrical components should be subjected to moisture. Therefore, it is important the oven is wiped down carefully. NEVER throw buckets of water over the oven or subject it to pressure washing from a hose or a pressure spray. If water or other liquid is spilled on the oven, make sure that none has entered the control box area before switching on. If in doubt, call your service company.
Do not spray chemicals or cleaning liquids directly on catalyst [ventless ovens]. Clean catalyst with damp cloth only. The catalyst must be kept clean and unobstructed to be effective.
To achieve the maximum efficiency of the oven, it is necessary to keep it clean. The frequency listed is only the factory’s recommendation. Your use and type of products will actually determine the frequency of cleaning.
CAUTION:
Oven must be cool. Do not use power-cleaning equipment, steel wool, or wire brushes on stainless steel surfaces.
DAILY CLEANING

1. Clean exterior surfaces of the oven by wiping it down with a mild detergent and clean water, or a commercial stainless steel cleaner.
2. Clean the interior by sweeping up all loose particles then wash with a mild detergent solution and rinse with clean water.
3. Clean the conveyor belt by wiping with a clean, water-dampened cloth to remove any baked-on crust or food product.

CAUTION:
Do not use caustic or alkaline base cleaner on the interior of the oven. This will ruin the aluminized finish of the oven interior. On the exterior of the oven, removal of deposits of baked-on splatter, oil, grease, or light discolorations may be removed with any of several commercial cleaners. Consult with your local supplier.
CAUTION:
When using cleaning solutions, be sure they meet local and national health standards.
WEEKLY CLEANING

1. Remove conveyor, disassemble, and clean. See the “Conveyor Removal” section for more information.
2. Remove fingers, disassemble, and clean. See the “Finger Removal” section for more information.

PREVENTATIVE MAINTENANCE

Although this oven has been designed to be as trouble-free as possible, periodic preventative maintenance is essential to maintain peak performance. It is necessary to keep the motors, fans, and electronics free of dirt, dust, and debris to ensure proper cooling. Overheating is detrimental to the life of all components mentioned.
The periodic intervals for preventive cleaning may vary greatly depending upon the environment in which the oven is operating.
You must discuss the need for preventive maintenance with your Authorized Service Agent to establish a proper program.
If there are any questions that the service agent cannot answer, please contact the Lincoln Technical service department at 800-678-9511.
INFORMATION ON USE OF OVEN
The Countertop Impinger Oven functions by directing high-velocity streams of heated air directly upon 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 Countertop Impinger
The oven can be as much as two (2) to four (4) times faster. Several factors may affect the cooking time of any special products such as oven temperature setting and conveyor speed. We encourage you to experiment with the oven by trying different temperature settings and belt speeds.

HOW TO OBTAIN SERVICE

If the oven fails to operate, check the circuit breaker to be sure it is turned on. Also, check the fuses on the back panel to be sure that they are good before you call the Authorized Service Agency. Contact the factory at 800-678-9511 for the name and number of the nearest Authorized Service Agency.
