EQUIPMENT DESCRIPTION

INTRODUCTION

This manual contains the necessary information to install, operate, maintain, and service the Lang model
ECO convection ovens.

Replacement parts should be genuine Lang parts. Failure to use genuine Lang replacement parts may
result in malfunction of the appliance or possible injury to the contractor or service technician.

PURPOSE AND FUNCTION

Convection ovens constantly circulate air over the product. This removes a layer of moisture and cool
air from around the product. This allows heat to penetrate the product more quickly. Cooking times are
shortened and cooking temperatures are reduced.

CAPABILITIES

This convection oven is suitable for cooking all types of products requiring baking or roasting.

ENVIRONMENTAL REQUIREMENTS

The following minimum spacing from combustible surfaces must be maintained: Sides – 2 inches, Back
– 2 inches

INSPECTION AND INSTALLATION

Upon receipt of the oven(s) any damage should be noted on the Bill of Lading and countersigned by the
carrier. If concealed damage is discovered the carrier should be notifi ed. All claims must be fi led with

the carrier.
Move the crate(s) containing the oven(s) as close to the place of installation as possible before removing

the protective crating. Uncrate the oven(s) and move them as close as practical to the fi nal installation
site.

Bolt the legs to the bottom oven, (See fi gure #2). Use the 3/8 – 16 x 5/8 Bolts, Hex Nuts and Washers
provided. There are pre-punched holes provided in the legs and oven bottom to aid in leg installation.
Now the oven can be set upright in or near its fi nal position.

SINGLE OVENS:

Connect power throught the knockout on the
bottom of the unit.

The oven can be placed in its fi nal position
and leveled. The oven is ready for initial start­up procedures now. (See page 7)

STACKED OVENS:

Be careful to route the power supply wire
between the two ovens using the holes
provided. Do not pinch or cut the supply wires
when stacking the ovens. Use the stacking kit
provided to secure the top oven to the bottom
oven.

The stacking kit contains four (4) identical
corner braces, one brace goes on each corner.
Drill pilot holes for the mounting screws using
the pre-punched holes as a guide. Secure the
top oven to the bottom oven with the sheet
metal screws provided. (See fi gure #3)
