OPERATION

User Safety Information

This appliance is intended for use in commercial
establishments where all operators are familiar with the
purpose, limitations, and associated hazards of this
appliance. Operating instructions and warnings must
be read and understood by all operators and users.

1. Make sure the unit is connected to the

appropriate power source.

2. Use hand protection when handling

hot items.

3. Preheat the unit for 30 minutes before use.

4. Be certain only hot foods are placed

into the cabinet.

5. Do not operate the holding cabinet

without

the Roll-in Cart on Models 12•20

and 20•20 or Slide-in Pan Rack on Model

10•18W.

HEATING CHARACTERISTICS

The cabinet is equipped with a special,
low-heat-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 a thermostat. The design and operational
characteristics of the cabinet eliminate 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 as much as
several hours.

The primary purpose of the Model 10•18W,
12•20, and 20•20 Holding Cabinet is to operate
as a functional extension of the Combitherm
Combination Oven/ Steamer. The combination
oven is for high volume production – the Halo
Heat companion holding cabinet preserves the
quality and extends the longest possible holding
life. The Slide-In-Pan-Rack for the 10•18W and
the Roll-In Cart for the 12•20 and 20•20 are
completely interchangeable between the
Combitherm Oven and the Halo Heat Companion
Holding Cabinet, along with compatible Alto­Shaam Quickchillers.

The Combitherm Combination Oven/Steamer,
along with the Halo Heat companion holding cabinet
and Alto-Shaam Quickchiller give the food service
operator the advantage of advance full-load
preparation, better work-load scheduling, and the
ability to hold the product for prolonged periods
without major deterioration.

BEFORE INITIAL USE:

Before operating the unit, clean both the interior and
exterior with a clean, damp cloth and mild soap
solution. Rinse carefully with a sponge and clean
water. Clean and install the Roll-in Cart on Models
12•20 and 20•20 or Slide-in Rack on the Model 10•18W.

OPERATION

●

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 set­point 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 will 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 " or "PFO " is displayed in the
Error Code L.E.D., the sensor is open­circuited. Follow Trouble Shooting Guide
instructions in this Operation and Care

Manual.

Short-Circuited

If "CCC " or "PFC " is displayed in the
Error Code L.E.D., the sensor is short­circuited. 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 programming mode.

Press and hold the UP or DOWN arrow
rocker button to change the value shown in

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 cabinet with hot food.

NOTE: Do not operate the holding cabinet without

the Roll-in Cart on Models 12•20 and 20•20
or Slide-in Pan Rack on Model 10•18W.

LOADING THE CABINET

Load the cabinet 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
