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 unit.

BEFORE INITIAL USE:

and exterior of the unit with a clean, damp cloth
and mild soap solution. Rinse carefully. Clean

and install the drawer warmer pan(s). The drawer

assembly is completely removable. Clean as a
sanitation measure.

HEATING CHARACTERISTICS

FOOD PRODUCT TIPS

Bread and Rolls

Breads and rolls are traditionally difficult to

hold for prolonged periods due to the very low
moisture content of these products. For best
results and longest possible holding life, it is
recommended these products be placed in a
plastic bag while in the warming drawer. Breads
and rolls should be held at a temperature no

higher than 120° to 140°F (49° to 60°C).

Potatoes

For the best results when holding potatoes:

1. Do not overcook.

Regardless of the temperature at which potatoes

are cooked or what type of oven is used, it is
important that this product does not achieve a
final internal product temperature in excess of

195°F (91°C). Over-cooking will further reduce

the moisture content and consequently, reduce
the holding life. Potatoes should be removed
from the oven when they reach an internal

temperature of approximately 190°F (88°C).

After they are removed from the oven, the
internal temperature will continue to increase.

The drawer warmer is equipped with a special
heating element. Through this Halo Heat concept,
the heating element is mounted against the walls of
the unit to provide an evenly applied heat source
controlled by a digital control. 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.

2. Allow potatoes to stabilize before placing
in drawer warmer.

When potatoes are removed from a conventional
high-temperature oven, they have an extremely
high surface temperature. If they are placed in
the drawer warmer while they are this hot on the
outside, moisture will be pulled from the inside
of the potato and condensation will form on the
outside. Holding results under these conditions
will not be totally satisfactory. Remove potatoes
from the oven and allow the surface temperature
to stabilize before placing them in the controlled
holding atmosphere of the drawer warmer.

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.

SET

5. Check to make certain the cabinet drawer is securely
closed, and using the Up and Down Arrow Keys,

set the temperature 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 optional drawer 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.

GENERAL HOLDING GUIDELINES

Chefs, cooks and other specialized food service
personnel employ varied methods of cooking. Proper
holding temperatures for a specific food product
must be based on the moisture content of the
product, product density, volume, and proper serving
temperatures. Safe holding temperatures must also
be correlated with palatability in determining the
length of holding time for a specific product.

Halo Heat maintains the maximum amount of product
moisture content without the addition of water,
water vapor, or steam. Maintaining maximum
natural product moisture preserves the natural
flavor of the product and provides a more genuine
taste. In addition to product moisture retention, the
gentle properties of Halo Heat maintain a consistent
temperature throughout the cabinet without the
necessity of a heat distribution fan, thereby preventing
further moisture loss due to evaporation
or dehydration.

In an enclosed holding environment, too much
moisture content is a condition which can be relieved.
A product achieving extremely high temperatures
in preparation must be allowed to decrease in
temperature before being placed in a controlled
holding atmosphere. If the product is not allowed to
decrease in temperature, excessive condensation will
form increasing the moisture content on the outside
of the product. To preserve the safety and quality
of freshly cooked foods however, a maximum of 1
to 2 minutes must be the only time period allowed
for the initial heat to be released from the product.

CARE AND CLEANING

CLEANING AND PREVENTATIVE MAINTENANCE

PROTECTING STAINLESS STEEL SURFACES

It is important to guard against corrosion

in the care of stainless steel

surfaces. Harsh, corrosive,

or inappropriate chemicals

can completely destroy the
protective surface layer

of stainless steel. Abrasive
pads, steel wool, or metal implements will abrade
surfaces causing damage to this protective coating
and will eventually result in areas of corrosion.
Even water, particularly hard water that contains
high to moderate concentrations of chloride, will
cause oxidation and pitting that result in rust
and corrosion. In addition, many acidic foods
spilled and left to remain on metal surfaces are
contributing factors that will corrode surfaces.

Proper cleaning agents, materials, and
methods are vital to maintaining the appearance
and life of this appliance. Spilled foods should be
removed and the area wiped as soon as possible
but at the very least, a minimum of once a day.
Always thoroughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly
as possible after rinsing.

CLEANING AGENTS

Use non-abrasive cleaning products designed for
use on stainless steel surfaces. Cleaning agents
must be chloride-free compounds and must not
contain quaternary salts. Never use hydrochloric

acid (muriatic acid) on stainless steel surfaces.

Always use the proper cleaning agent at the
manufacturer's recommended strength.
Contact your local cleaning supplier for
product recommendations.

CLEANING MATERIALS

with the proper cleaning agent and a soft, clean
cloth. When more aggressive methods must be
employed, use a non-abrasive scouring pad on
difficult areas and make certain to scrub with the
visible grain of surface metal to avoid surface

pads, or scrapers to remove food residue.

ANY KIND. DO NOT USE WATER JET

The cleanliness and appearance of this equipment will contribute considerably to
operating efficiency and savory, appetizing food. Good equipment that is kept clean
works better and lasts longer.

THOROUGHLY CLEAN DAILY:

1. Disconnect unit from power source, and let cool.

2. Remove, cover or wrap, and refrigerate food.

3. Remove drawer pans and clean separately.

The drawer assembly is completely removable.
Remove from the cabinet and clean to prevent a
build-up of food residue from interfering with
the function of the drawer assembly. Regular
cleaning will help prolong the life of these parts.

4. Clean interior metal surfaces

of the unit with a damp, clean
cloth and any good commercial
detergent or grease solvent at
the recommended strength.
Use a plastic scouring pad or
oven cleaner for difficult areas. Rinse carefully to
remove all residue and wipe dry.

NOTE: Avoid the use of abrasive cleaning,

compounds, chloride based cleaners, or
cleaners containing quaternary salts. Never

use hydrochloric acid (muriatic acid) on

stainless steel.

5. Wipe control panel, vents, handles, and gaskets
thoroughly since these areas harbor food debris.

6. Interior can be wiped with a sanitizing solution
after cleaning and rinsing. This solution must
be approved for use on stainless steel food
contact surfaces.

7. To help maintain the protective film coating on
polished stainless steel, clean the exterior of the
unit with a cleaner recommended for stainless
steel surfaces. Spray the cleaning agent on
a clean cloth and wipe with the grain of the
stainless steel.

Always follow appropriate state or local health

(hygiene) regulations regarding all applicable

cleaning and sanitation requirements for
foodservice equipment.

Food fl avor and aroma are usually so closely related
that it is diffi cult, if not impossible, to separate them.
There is also an important, inseparable relationship
between cleanliness and food fl avor. Cleanliness, top
operating effi ciency, and appearance of equipment
contribute considerably to savory, appetizing foods. Good
equipment that is kept clean, works be er and lasts longer.

Most food imparts its own particular aroma and many
foods also absorb existing odors. Unfortunately, during
this absorption there is not distinction between GOOD
and BAD odors The majority of objectionable fl avors and
odors troubling food service operations are caused by
bacteria growth. Sourness, rancidity, mustiness, stale or
other OFF fl avors are usually the result of germ activity.

The easiest way to insure full, natural food fl avor is
through comprehensive cleanliness. This means good
control of both visible soil (dirt) and invisible soil
(germs). A through approach to sanitation will provide
essential cleanliness. It will assure an a ractive
appearance of equipment, along with maximum effi ciency
and utility. More importantly, a good sanitation program
provides one of the key elements in the prevention of
food-borne illnesses.

A controlled holding environment for prepared foods is
just one of the important factors involved in the prevention
of food-borne illnesses. Temperature monitoring and
control during receiving, storage, preparation, and the
service of foods are of equal importance.

The most accurate method of measuring safe temperatures

temperature. A quality thermometer is an eff ective tool for
this purpose, and should be routinely used on all products

is both cost eff ective and relatively simple. While HACCP

of both hot and cold foods is by internal product

that require holding at a specifi c temperature.

A comprehensive sanitation program should focus on
the training of staff in basic sanitation procedures. This
includes personal hygiene, proper handling of raw
foods, cooking to a safe internal product temperature,
nd the routine monitoring of internal temperatures from
receiving through service.

Most food-borne illnesses can be prevented through
proper temperature control and a comprehensive
program of sanitation. Both these factors are important
to build quality service as the foundation of customer
satisfaction. Safe food handling practices to prevent food­borne illness is of critical importance to the health and
safety of your customers.

HACCP, an acronym for Hazard Analysis (at) Critical
Control Points, is a quality control program of operating
procedures to assure food integrity, quality, and safety.

THERMOSTAT ACCURACY

The electronic thermostat is a precise instrument
and is designed to offer trouble free service. If
you suspect the temperature inside the holding
compartment does not match the temperature
indicated on the digital display, follow the
instructions listed below.

1. Check to make certain the unit voltage matches
the power source. A power source less than
that required to operate the unit will result in
inaccurate temperatures.

2. Verify the temperature inside the holding
compartment with a quality thermal indicator.

a. Completely empty the holding compartment.

b. Make certain the holding cabinet sensor,

located inside the holding compartment, is
completely clean.

c. Suspend the thermal indicator in the center of

the holding compartment.

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.
