Unpacking and Setup

The Alto-Shaam Cooking and Holding Oven has been thoroughly tested, checked for calibration, and inspected to ensure only the highest quality oven is provided. When you receive your oven, check for any possible shipping damage and report it at once to the delivering carrier.

(See Transportation Damage

and Claims section of this manual.)

The oven, complete with unattached items and accessories, may be delivered in one or more packages. Check to insure that all the following items have been received with each standard unit:

2 Ea. Drip Pans 1 Ea. External Drip Tray 4 Ea. Oven Side Racks 4 Ea. Casters 6 Ea. Wire Shelves 16 Ea. Caster Mtg. Screws

The heavy duty models have the full perimeter bumper and casters installed at the factory.

Save all the information and instructions packed inside the oven. Complete and return the warranty card to the factory as soon as possible to insure prompt service in the event of a warranty parts and labor claim.

Note: Any and all claims for warranty must include the

full model and serial number of the unit.

This cook and hold oven is designed for the purpose of heating food to its proper temperature and maintaining the hot food at a temperature for safe consumption. It must be installed in a location that will permit it to function for its intended purpose and allow adequate access for proper cleaning and maintenance.

Oven Characteristics

The oven is equipped with a special, high-heat-density, heating cable. Through the Halo Heat concept, the heating cable is mounted against the walls of the cooking cavity to provide an evenly applied heat source controlled by a thermostat. The design and operational characteristics of the oven eliminates the need for a moisture pan or a heat circulating fan. Through even heat application, the quality of a food product is maintained up to several hours.

Electrical Installation

1.An identification tag is permanently mounted on

the oven.

SAMPLE

2.All models at 208/240 volts are dual rated units with a conversion switch mounted under an access cover on the rear of the oven, near the power cord.

With the voltage conversion switch in the 200 volt through 208 volt (

UPPER) position, the oven will function properly with a source voltage of between 200 volts and 208 volts.

With the voltage conversion switch in the 220-240 volt (

LOWER) position, the unit will function properly with a

source voltage of between 220 volts and 240 volts.

NOTE: All 208/240 volt units are shipped from the

factory with the voltage conversion switch in the 220-240 volt position. Again, ensure that the voltage conversion switch position and the available power source match.

3. If necessary, a proper receptacle or outlet must be installed by a licensed electrician in accordance with applicable local electrical codes. This oven must be grounded in accordance with the requirements of the National Electrical Code or applicable local country codes.

Ensure power source matches voltage stamped on oven nameplate.

At no time should the oven be steamed cleaned, washed down, or flooded with water or liquid solution. Do not use water jet to clean. Severe damage or electrical hazard could result.

Disconnect oven from power source before cleaning or servicing.

Cold food for rethermalization or reheating must never be added to the oven while hot food is being held.

INSTALLATION

Start-Up

For the best service, the oven should be installed level. The oven should NOT be installed in any area where it may be

affected by steam, grease, dripping water, high temperatures or any other severely adverse conditions.

1. Before operating the oven, clean both the interior and exterior of the unit with a damp cloth and mild soap solution. Rinse carefully.

2. Install the external drip tray on the lower front of the oven. See installation instructions located in this manual.

3. Clean and install the oven side racks and oven shelves. Shelves should be positioned with the curved end up and

toward the back of the oven. Insert the drip pan on the interior bottom surface of the oven.

4. Before operating the unit with product, become familiar with the operation of the controls. Read the following

“

General Operation” section of this manual and operate the various control functions.

INSTALLATION

Thermostat/Indicator Light Sequence

Whenever the start-up procedure has been

completed, the indicator light will indicate the power ON/OFF condition of the heating cable and consequently, the cycling of the oven as it maintains the dialed cavity temperature. If the light does not indicate after normal start-up, the main power source, the main power breaker, and/or the oven control circuitry must be checked. If a oven compartment does not hold the temperature as dialed, the calibration of the thermostat must be checked. (SEE THE PARAGRAPH

ON THERMOSTAT CALIBRATION

.) If a cooking compartment fails to heat or heats continuously with the thermostat off, the thermostat must be initially checked for proper operation. If all is in order, a continuity and resistance check of the heating cable should be made. (SEE THE CIRCUIT DIAGRAM.)

Thermostat Calibration

At 250° F (121° C) COOK

and 140° F (60° C) HOLD

The thermostat is precision calibrated at the

factory. Normally, no adjustment or recalibration is necessary unless the thermostat has been mishandled in transit or changed or damaged while in service. A thermostat with a sensing bulb operates on hydraulic pressure. Consequently, any bending of the bulb results in a change in its volume and displaces the accuracy of the thermostat calibration.

A thermostat should be checked or recalibrated by placing a quality temperature indicator at the center of an empty oven cavity. DO NOT CALIBRATE WITH FOOD PRODUCT IN THE OVEN. The temperature must be allowed to stabilize at one particular setting for at least two hours. Following temperature stabilization, the center of the thermal swing of the cavity temperature should approximately coincide with the thermostat dial setting.

The calibration screw of the thermostat is located in the dial shaft. With the shaft held stationary, a minute clockwise motion of the calibration screw appreciably lowers the thermostat setting while a reverse motion results in the opposite condition. After achieving the desired cycling of the thermostat, the calibration screw must be sealed in place with a few drops of sealant.
