UNPACKING and SET-UP

The Alto-Shaam Hot Merchandiser has been thoroughly tested, checked for calibration, and inspected to insure only the highest quality cabinet is provided. When you receive your unit, check for any possible shipping damage and report it at once to the delivering carrier.

See Transportation Damage and Claims section located in

this manual.

The cabinet, complete with unattached items and accessories, may be delivered in one or more packages. Make certain the number of packages received matches the packing list and the accompanying bill of lading.

Save all the information and instructions packed inside the cabinet. 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.

The unit should not be used in any area where it may be affected by steam, grease, dripping water, or high temperatures. The unit should be installed level to work properly.

In order to maintain standards established by the National Sanitation Foundation, models mounted directly on top of an base or counter must be sealed to both the base and floor, or counter, with a R.T.V. or silastic meeting N.S.F. requirements. Otherwise, these units must be mounted on legs of a sufficient 4" (102mm) height to provide minimum unobstructed space beneath the unit. If these directions are not followed, the warranty will become null and void.

(Refer to counter layout in this manual.)

NOTE: Any claims for warranty must include

the full model number and serial number

of the cabinet.

WARMING CHARACTERISTICS

The merchandiser is equipped with a special, lowheat-density, heating cable. Through the Halo Heat concept, the heating cable is mounted against the walls of the warming compartment to provide an evenly applied heat source, controlled by an electronic thermostat. The design and operational characteristics of the unit eliminate the need for a moisture pan or a heat circulating fan. Through even heat application, the quality of food is maintained for short periods or for longer time periods, up to several hours. The heated compartment is equipped with an electronic thermostat, indicator light, and digital display to monitor the interior air temperature.

Read this manual thoroughly before using this merchandiser, and keep this manual in a safe and easily accessible area.

1. Before operating the merchandiser, clean the interior

and exterior of the unit with a clean, damp cloth and

mild soap solution. Rinse carefully.

2. Clean and install the side racks, cabinet wire shelves

and the bottom baffle pan.

3. Clean the glass with a window cleaner.

4. After final hook-up, locate the circuit breaker box

under the unit and flip breaker switch to the ON

position for full power to the merchandiser.

5. Check the operating temperature to make sure the

merchandiser is functioning within the guidelines

recommended for this unit.

Thermostat Control Description and Function

The L.E.D., Light Emitting Diode, referred to is an electronic device providing illumination. The control has a three-digit L.E.D. display. When the warming cabinet is in operation, the L.E.D. will show the chamber's internal temperature. The display will also show programming and diagnostic information.

ON/OFF Rocker Switch

The Power On/Off Rocker Switch positions may be marked with the international "

I" for

On and "O" for Off.

UP/DOWN Arrow Rocker Button

The UP/DOWN arrow rocker button is used to increase or decrease the set-point temperature. The minimum set-point temperature is 90°F (32°C) while the maximum set-point temperature is 200°F (93°C).

SET Button

The SET button is used to display the current set-point temperature or program a new set-point temperature. Pushing the SET button once will display the set-point temperature value for five seconds. Holding the SET button allows the programming mode to become active.

L.E.D. Display

The L.E.D. display will show the set-point temperature value when programming, or the warming chamber's temperature when calling for heat. When programming a new set-point temperature, the L.E.D.1 indicator with blink. When a new set-point temperature is chosen, the Chamber Temperature L.E.D. will flash three times to confirm.

HEAT INDICATOR L.E.D.

The Heat Indicator L.E.D. will illuminate and remain lit while the unit is calling for heat. It will go out when the air temperature inside the warming chamber reaches the set-point temperature on the control.

ERROR CODE DISPLAYS

Open-Circuited

If "ooo" is displayed in the Error Code L.E.D., the sensor is open-circuited. Follow Trouble Shooting Guide instructions in this Operation and Care Manual.

Short-Circuited

If "ccc" is displayed in the Error Code L.E.D., the sensor is short-circuited. Follow Trouble Shooting Guide instructions in this Operation and Care Manual.

ERROR CODE INDICATOR L.E.D.

If either of the above mentioned errors codes should occur, the Error Code Indicator L.E.D. will be illuminated and remain so until error is cleared.

Programming and Operating Thermostat Control

Turn Power On

Press the "ON" or "I" position of the rocker switch to turn on control.

CHANGE SET-POINT TEMPERATURE

Press and hold

the SET button for at least 3 seconds. After L.E.D.1 indicator blinks, release the Set Button. The control is now in the program-

ming mode.

Press and hold the UP or DOWN arrow rocker button to change the value shown in the display. Store the value by pressing the SET button.

The new set-point value will flash three times to confirm.

HEAT INDICATOR L.E.D.

The Heat Indicator L.E.D. will illuminate as the warming chamber calls for heat. It will extinguish when the warming chamber's interior temperature reaches the set-point.

PREHEATING THE UNIT

Always preheat the unit at 200°F (93°C) for 30 minutes before loading the merchandiser with hot food.

LOADING THE CABINET

Load the merchandiser with hot food only. The purpose of

this unit is to maintain hot food at proper serving temperature. Use a food thermometer to make certain all food has reached

an internal temperature range of 140° to 160°F (60° to 71°C). Do not fill cabinet closer than 2" from the sensor. Make certain door is securely closed after loading. Reset the control

to 160°F (71°C).

This will not necessarily be the final

setting.

Proper temperature range for the food being held will depend on the type and quantity of product. It is advisable to periodically check the internal temperature of each item to assure maintenance of proper food serving temperature.

CAUTION

The unit should be unplugged and a qualified service technician should be consulted if any of the following situations occur:

• The Heat Indicator L.E.D. does not illuminate after normal start-up.

• The warming cabinet does not hold the temperature as set.

• The warming cabinet fails to heat with the L.E.D. illuminated.

• The cabinet heats continuously with the control “OFF”.

• Refer to Trouble Shooting Guide in this manual.

ELECTRONIC CONTROL ACCURACY

The electronic control is a precise instrument and is designed to offer trouble-free service. If you suspect the temperature inside the warming cabinet does not match the temperature indicated on the digital display, after stabilizing, follow the instructions listed below.

1. Make certain the power meets the requirements of the appliance, voltage and current rating as indicated on identification tag.

2. Verify the temperature inside the warming cabinet with a quality thermal indicator.

A. With the exception of the metal shelves, completely

empty the warming cabinet.

B. Make certain the sensor, located inside the warming

cabinet at the ceiling, is completely clean.

C. Suspend the thermal indicator in the center of the

warming cabinet.

D. Allow the temperature, set on the electronic thermostat,

to stabilize for a minimum of one hour before comparing the digital display with the reading on the thermal indicator.

DO NOT OPEN THE CABINET DOOR(S) DURING THE TEMPERATURE STABILIZATION PERIOD.

If the reading on the thermal indicator does not match the digital display within 10°F (6°C), contact a qualified service technician for appropriate action.
