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

NOTE: All claims for warranty must include the

full model number and serial number of the
cabinet.

The cabinet is equipped with a special heating cable.
Through this Halo Heat concept, the heating cable is
mounted against the walls of the unit to provide an
evenly applied heat source controlled by a 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 products is maintained up to several
hours or more.

1. An identification tag is permanently mounted on
the cabinet.

2. Plug cabinet into a properly grounded receptacle
ONLY, positioning the unit so the power supply
cord is easily accessible in case of an emergency.

3. If necessary, a proper receptacle or
outlet configuration as required for this unit,
must be installed by a licensed electrician
in accordance with applicable, local electrical codes.

Stacking Instructions

STACKING PLATE INSTALLATION

Kit #5001359

1. Measure the length and width of the top surface of the
cabinet to be positioned at the bottom of the stacking
equipment combination. Add 1/8-inch to both the length
and the width dimension.

2. Turn the cabinet to be placed at the top of the stacking
combination upside down so that the top surface is on the
floor. Remove the eight (8) bolts located at the front (door
side) and at the rear of the cabinet. Replace the bolts with
the eight (8) nylon plugs provided in the stacking kit (RI-

26196).

3. Place the four (4) stacking plates at each corner of the
cabinet. Position the plates with the upright flange
pointing up and to the outside of the cabinet. Align the
holes in the stacking plates with the predrilled holes in the
bottom of the cabinet using both the length and width
dimensions obtained in step 1.

4. When the correct alignment has been achieved, loosely
fasten each stacking plate with four (4) screws provided in
the stacking kit. DO NOT TIGHTEN SECURELY since
minor adjustments may be necessary.

5. Stack the cabinets and make any necessary minor
adjustments to the stacking plates. When properly aligned,
the door on the top cabinet should be flush with the door
on the bottom cabinet.

6. When proper alignment has been made, remove the top
cabinet from the stacking combination. Firmly secure all
four stacking plates by individually removing each screw
and reattaching it in combination with one of the square
washers provided in the stacking kit.

OPERATION - MANUAL CONTROL

1. Preheat at 200°F (93°C) for 30 minutes.

When the thermostat is turned clockwise to the ON
position, the indicator light will illuminate and will
remain lit as long as the unit is calling for heat.
Allow a minimum of 30 minutes of preheating before
loading the holding cabinet with food. Closing the
vents on the inside of the door will speed up the
process. The indicator light will go OUT after
approximately 30 minutes, or when the air
temperature inside the unit reaches the temperature
set by the operator.

2. Load the cabinet with hot food only.

The purpose of the holding cabinet is to maintain
hot food at proper serving temperatures. Only hot
food should be placed into the cabinet. Before
loading the unit with food, use a food thermometer
to make certain all food products are at an internal
temperature range of 140° to 160°F (60° to 71° C).
All food not within the proper temperature range
should be heated before loading into the holding
cabinet.

3. Reset the thermostat to 160°F (71°C).

Check to make certain the cabinet door is securely
closed, and reset the thermostat to 160°F (71°C).

THIS WILL NOT NECESSARILY BE THE FINAL
SETTING.

The proper temperature range for the food being
held will depend on the type and quantity of
product. Whether or not the door vents should be
open or closed will also depend on the type of food
being held. When holding food for prolonged
periods, it is advisable to periodically check the
internal temperature of each item to assure
maintenance of the proper temperature range.

UP/DOWN ARROW KEY

The up and down arrow keys are used for a variety of settings
when selecting the holding temperature. If an arrow key is pressed
and released the display will show the current set temperature for
two seconds. If an arrow key is held (at least eight seconds), the
value will change at a rapid rate. If the arrow key is pressed and
released in rapid succession, the set temperature will change by
increments of one degree.

ENABLE/DISABLE BEEPER

A beeper sounds when an error code is displayed.
To choose between beeper on and beeper off mode, the
control must be OFF, then press and hold the down arrow
key until either "ON" or "OFF" is shown in the LED display.
Release arrow key when desired mode is displayed.

FAHRENHEIT / CELSIUS

With the control OFF, to choose between Fahrenheit and Celsius,
press and hold the up arrow key until either °F or °C is shown

The control has a four-digit LED display. When the display
is ON, it will show current holding temperature, as well as
diagnostic information.

CONTROL LOCK

The warmer controls can be locked so that no changes can
be made to the set temperature.

To

lock the display, press and hold the ON/OFF key and
the Up Arrow key at the same time. The lock indicator will
illuminate. When the lock indicator is illuminated, additional
programming will not be functional other than the key
sequence required to unlock the panel.

To

unlock the display, press and hold the ON/OFF key and
the Down Arrow key at the same time. The lock indicator
will extinguish. The panel keys will resume normal function.

1. Preheat at 200°F (93°C) for 30 minutes.

Press the ON key, and set the temperature to
200°F (93C°) by using the UP/DOWN arrow
keys. Allow a minimum of 30 minutes
preheating time before loading the drawer
warmer with food. The LED heat indicator
light will go “OUT” after approximately 30
minutes preheat time, or when the air
temperature inside the unit reaches the
temperature set by the operator.

2. Load with pans of hot food only.

The purpose of the warmer is to maintain hot
food at proper serving temperature. Only hot
food should be placed into the unit. Before
loading with food, use a food thermometer to
make certain all products are at an internal
temperature range of 140° to 160°F (60° to
71°C). Any food product not within the
proper temperature range should be heated
before loading into the unit.

3. Reset the control to 160°F (71°C).

Check to make certain the drawer is securely
closed, and reset to 160°F (71°C) by using
the UP/DOWN keys.

THIS WILL NOT NECESSARILY BE THE
FINAL SETTING.

The proper temperature range will depend on
the type and quantity of product. When
holding food for prolonged periods, it is
advisable to periodically check the internal
temperature of each item with a food
thermometer to assure maintenance of the
proper temperature range of
140° to 160°F (60° to 71° C).

EXCLUSIVE FEATURES

HEAT RECOVERY

The patented SureTemp™ heat recovery system in this unit will immediately compensate for any loss of heat when
the door is opened. In order to maintain a more consistent cavity temperature, the control will automatically
apply heat to the unit's interior while the door is open and for a short time after the door is closed. If the door
remains open for more than three minutes, the solid state electronic control will sound three rapid beeps every
ten seconds until the door is closed.

HACCP & KITCHEN MANAGEMENT SOFTWARE

These holding units can be ordered equipped with the HACCP/Kitchen Management option for connection
to a PC. The units also have the capability of being connected to the internet via a Gateway device. This
can provide temperature recording data as well as setup and diagnostic information which can be used for
HACCP documentation.

Shelf Timer Keys

The Multiple Shelf Timer Key option is available for hot food holding units with the electronic control.

These keys monitor food safety by using a timer-based "First-In, First-Out" product management

system. Products should be cooked to HACCP recommended internal temperature and then held in

the unit. The Timer system allows operator to select holding times when the unit is loaded.
