Leg Installation

4” legs are available for single countertop installations. Single and double deck installations require 16” or 28” stand installation, casters may also be used in certain situations.

To install the 4” legs, place some

cardboard on the oor and gently tip

the unit onto its back. Fasten the four, 4” legs into the threaded holes located on the bottom of the unit. Gently lift the oven into its operating position.

IL1430

Align the stand with the bottom of the unit and secure with the hardware provided. With the assistance of carefully raise the unit to its vertical position.

Stacking the Ovens

Two alignment pins (pn: 2C-20108-11) are needed if you intend on stacking two ECOH on each other as shown. These pins must be requested at the time of purchase, or call your Lang authorized service agent, or Lang parts department at 314-678-6315.

Having completed the previous step remove any and all button plugs from the lower unit, so the upper unit will lay properly.

Lay the upper unit on its back and screw the alignment pins into the two rear holes.

With assistance lift the upper unit onto the lower unit, being certain that the alignment pins go into the alignment holes, as shown here.

NOTE: Each unit must have separate electrical connections

Ventilation and Clearances

Standard minimum clearance from combustible construction is as follows.

4” from side

4” from back

6” from oor

• These ovens may be set directly, without legs, on a curbed base or non-combustible oor.

• If the oven is set without legs on a non-combustible oor or a curbed base, maintain a 4-inch back

clearance.

• If the oven is set directly against a non-combustible back wall, maintain a 6-inch clearance to the oor.

• Do not install the oven closer than 12 inches from an uncontrolled heat source (char broiler etc.) on the right side.

• Keep the area free & clear of combustible material, and do not obstruct the ow of combustion or

ventilation air.

• The installation of any components such as a vent hood, grease extractors, and/or re extinguisher

systems, must conform to the applicable nationally recognized installation standards.

General Operation & Programming cont.

Here are some things to remember when loading your oven.

• When loading and unloading the oven, stage products and racks so the oven door is opened for the least amount of time.

• Be sure that racks are level within the oven.

• Bent or warped pans can greatly affect the evenness of the cook or bake.

• If using baker’s parchment, be sure the parchment does not blow over the product. That will create an uneven bake.

• Load each shelf evenly. Spaces should be maintained equally between the pan and oven walls, front and back.

• Do not overload pan’s this will create an uneven bake.

• For best baking results, load the oven from the center out during random loading.

ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM

COMBUSTIBLE MATERIALS.

KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS OCCUR,

CAUTION

CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.

MAINTENANCE

• Oven interiors should be wiped down daily and thoroughly cleaned weekly using warm water and mild detergent. DO NOT use caustic cleaners.

• The appliance should be thoroughly checked at six-monthly intervals by a qualied technician (heating unit, mechanical stability, corrosion...) with particular emphasis on all control and safety devices.

CLEANING

• Always start with a cold oven.

• The stainless exterior can easily be cleaned using stainless steel cleaner.

• Always follow the cleaner manufacturer’s instructions when using any cleaner.

• Care should be taken to prevent caustic cleaning compounds from coming in contact with the fan wheel.

• The oven racks, rack slides, may be cleaned outside the oven cavity using oven cleaner.

• Using any harsh chemicals will result in the removal of the ETC coating and etching of the porcelain below it. The oven interior should only be cleaned using a mild soap and a non metal scouring pad.

DO NOT use caustic cleaners.

• Always apply stainless steel cleaners when the oven is cold and rub in the direction of the metal’s grain.

KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR

HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.
