3.1 Receiving the Range

Upon receipt, check for freight damage, both visible and concealed. Visible
damage should be noted on the freight bill at the time of delivery and signed by the
carrier's agent. Concealed loss or damage means loss or damage, which does not
become apparent until the merchandise has been unpacked. If concealed loss or
damage is discovered upon unpacking, make a written request for inspection by the
carrier's agent within 15 days of delivery. All packing material should be kept for
inspection. Do not return damaged merchandise to Lang Manufacturing Company.
File your claim with the carrier.

3.2 Location

Prior to un-crating, move the range as near its intended location as practical. The
crating will help protect the unit from the physical damage normally associated
with moving it through hallways and doorways.

3.3 Un-crating

Uncrate range as close to installation location as possible. The range is packaged
on a pallet, wrapped in plastic to protect the unit from moisture and surrounded by
a wooden frame. Remove the wood crating carefully. Improper use of tools can
result in damage to the equipment. Remove and discard the plastic wrap.
Desiccant bags on top of the range should also be discarded. Protective paper on

UNPACKING

top of the range may be left until the installation is complete.

The range is raised on blocks to enable ease of handling when removing from pallet
with forklift or straps. Use extreme care regardless of method used and be aware of
gravity center, especially with banks of multiple units.

PLEASE NOTE:

Legs, manuals, racks, rack slides, griddle cleaning tools, fryer smother covers and
remote overhead switch boxes, where applicable, are packed inside the oven cavity
and should remain there until the unit is at the final installation location.

Desiccant bags have been placed inside electrical cavity and must be removed
before operation.

4.1 Electrical Connection

Electrical connection can be hooked into the bottom front, below the terminal
block, or at the right back of the unit behind the terminal block.

4.2 Range Voltage

The Lang Model CLR36-H-U can be operated on 480 Volts.

5.1 PRE-POWER ON

Initial Start-up

Before the initial use of the range, the oven must be thoroughly allowed to dry
itself out. This is done be setting the thermostat to 350°. Allow the range oven to
heat until all vapor and condensation has been eliminated. For best results allow
the oven to thoroughly dry out. Allow 8 to 12 hours for this process. Clean top
plates thoroughly. Apply salad oil. Turn each plate thermostat to a low position
and allow plate to heat for three hours.

INITIAL START UP

NOTICE:

Somewhere along the rising temperature curve between
200° and 300° a moderate amount of smoke may issue from

in and around the Range. The smoke may be repeated
somewhere around 350°. Preservation oils and oil
accumulated during manufacturing may be coming off as
smoke in these temperature ranges. Do no be alarmed.

OPERATION

CAUTION:

CAUTION:

ALWAYS KEEP THE AREA NEAR THE APPLIANCE
FREE FROM COMBUSTIBLE MATERIALS.

KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND
DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO
AVOID THE DANGER OF SLIPS OR FALLS.

6.1 Range Controls

The hot top controls are, from front to back. The first set of knobs control the front
left and right. The second set of knobs control the rear left and right. Each section
has a 850°F thermostat. The oven temperature is controlled by a 550°F thermostat
that is located below the range top controls.

6.2 General Operation

The oven must be thoroughly preheated before satisfactory baking can be done.
The oven will not bake uniformly if not sufficiently preheated. After preheating let
the oven cycle 2 or 3 times to ensure complete heating of the entire oven cavity.

The “Roasting and Baking” oven is equipped with a removable rack. For baking
pies, bread, or for roasting operations, the rack may be placed directly on the metal
deck and the pans placed on the rack. For baking cakes or pastries the rack should
be located in the lower position provided by the rack supports at the sides of the
range and the pans placed on the rack in this lower position.

NOTE: Always place the pans symmetrically on the rack for best results. Keep the
oven door closed as much as possible. Excessive door opening will cool the front
section of the oven and products placed near the front are likely to bake slower. It
is desirable to keep the front edge of the pans at least several inches back from the
inside of the door (when closed). Do not permit air from a window or fan to blow
into the oven; it will cause uneven heating.

WARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS.

NEVER SPRAY OR HOSE CONTROL CONSOLE,
ELECTRICAL CONNECTIONS, ETC.

CLEANING

CAUTION:

MOST CLEANERS ARE HARMFUL TO THE SKIN,
EYES, MUCOUS MEMBRANES AND CLOTHING.
PRECAUTIONS SHOULD BE TAKEN TO WEAR
RUBBER GLOVES, GOGGLES OR FACE SHIELD AND
PROTECTIVE CLOTHING. CAREFULLY READ THE
WARNING AND FOLLOW THE DIRECTIONS ON THE
LABEL OF THE CLEANER TO BE USED.

7.1 After each meal Cleaning

Empty the grease drawer often or whenever it is 3/4 full. Remove the grease
drawer after each meal and wash the inside and outside of the drawer.

Keep the hot top surface clean.

Clean the exterior of the appliance with a hot water and chlorine solution to
maintain a gleaming appearance.

Be sure to rinse thoroughly and coat the cooking surface with a thin film of oil to
prevent rusting.

7.2 Daily

The range should be thoroughly cleaned at least once a day in addition to the
normal after meal cleaning to insure against the accumulation of foreign material.
Keep the inside of the oven and metal deck clean, particularly around door opening,
door edges and at bottom of door opening so that the door may close tightly.
