OPERATION
1. Check that the unit is connected to the
appropriate power source.
2. Slide open the control panel. Press
power and light switches on.
3. Turn thermostat(s) to a predetermined
number and preheat for 30 minutes.
Each shelf has its own thermostat control
numbering from 0 to 10. When the thermostat is
turned clockwise to the determined number, the
indicator light will illuminate and will remain
lit as long as the shelf is calling for heat.
The indicator light will go OUT when the
temperature on the glass top reaches the set
number determined by the operator. It will
then cycle “oN/off” at this holding point.
The shelves will hold a steady even heat as
assigned. The user must determine what set
point can be used regarding each food item
held on its corresponding shelf. It is
recommended that a similar food product be
placed on each shelf.
Always use the top shelf for the highest heat
assignment, and the bottom shelf for the lowest
heat assignment.
The proper temperature range for the food
being held will depend on the food type,
the packaging, and the quantity of product.
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.
4. Load prepackaged hot foods into the
merchandiser.
Before loading food into the unit, use a pocket-
type meat thermometer to make certain all
products have reached an internal temperature
of 160° F (71°C) or higher. If any food product
is not at proper serving temperature, use a Halo
Heat cooking and holding oven or Combitherm
Oven to bring the product within the correct
temperature range.
5. Occasionally stir or rotate foods
as needed.
Wipe spills immediately to assure maximum
eye appeal and minimize end-of-the-day
cleanup.

OPERATION
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.
When product is removed from a high temperature
cooking environment for immediate transfer into
equipment with the lower temperature required
for hot food holding, condensation can form on the
outside of the product and on the inside of plastic
containers used in self-service applications. Allowing
the product to release the initial steam and heat
produced by high temperature cooking can alleviate
this condition. 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.
This appliance is equipped with a thermostat
indicating a range of between 0 and 10. Use a metal-
stemmed thermometer to measure the internal
temperature of the product(s) being held. Adjust the
thermostat setting to achieve the best overall setting
based on internal product temperature.

CARE AND CLEANING
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
The cleaning function can usually be accomplished
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
scratches. Never use wire brushes, metal scouring
pads, or scrapers to remove food residue.

pg. 12 HSM inStallation/operation/Service Manual
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 better 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 attractive
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
of both hot and cold foods is by internal product
temperature. A quality thermometer is an effective tool for
this purpose, and should be routinely used on all products
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 food-
borne 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.
Taking steps necessary to augment food safety practices
is both cost effective and relatively simple. While HACCP
guidelines go far beyond the scope of this manual,
