OPERATIONAL PROCEDURES
1. DO NOT ADD WATER TO THE CASE
It is not necessary to add water to the case. As a matter of fact,
adding water is not recommended since water will accelerate the
deterioration of the product, and may damage the case.
2. PLACE DIVIDERS and SERVING PANS IN CASE
A complete pan configuration layout is located in this manual.
It is VERY
configuration you choose, pan separator bars or divider bars
must be used to close all gaps between pans, and all gaps
between the pans and the edges of the display case. As a
consequence, if this is not done, heat distribution can be uneven
and uniform temperature will be difficult to hold. If needed,
additional pan divider bars are available.
3. TURN POWER AND/OR BREAKER SWITCH ON
They are located on the control side of the unit.
4. TURN DISPLAY LIGHTS “ON” AND SET THE
THERMOSTATS AT NUMBER “10” TO PREHEAT
A indicator light will illuminate when the thermostats are turned
“ON.” The light indicators will remain lit as long as the unit is
preheating or calling for heat. The unit should be preheated, at
the number 10 setting, for a minimum of 45-60 minutes before
loading the case with food. When preheating is completed, or
whenever the unit reaches any temperature set by the operator
between 1 and 10, the indicator lights will go “OUT”.
5. LOAD HOT FOODS INTO THE CASE
Be certain only hot food is transferred into the case.
Before loading food into the unit, use a pocket-type meat
thermometer to make certain all products have reached an
internal temperature of 140° to 160° F (60° to 71°C). If any
food product is not at proper serving temperature, use a Halo
Heat cooking and holding oven, set at 250° to 275°F (121°
to 135°C), or a Combitherm oven, to bring the product within
the correct temperature range. Be certain only hot PREPACKAGED foods with heat tested containers are used in the
self-service section of the case.
6. RESET THERMOSTATS AS NEEDED
After all food is loaded into the display case and the doors are
closed, reset the thermostats to the number “8” setting. THIS
WILL NOT NECESSARILY BE THE FINAL SETTING. Since
proper temperature range depends on the type of products and
the quantities being held, it is necessary to periodically use a
pocket thermometer to check each item to make certain the
correct temperatures are being maintained. Proper temperature
range is between 140° and 160°F (60° and 71°C). Normally,
this will require a thermostat setting of “8,” but self-service
sections will always require a higher thermostat setting.
7. SERVE FRESH HOT FOOD
Keep hot foods looking fresh. Occasionally stir or rotate foods as
needed. Serve products in the proper package or container. Keep
doors closed after serving. Wipe spills immediately to assure
maximum eye appeal and to ease end-of-the-day cleanup.
important to note, no matter what type of pan
CARE and CLEANING
Hood glass extended to the full upright
position is stabilized through the use
of gas struts designed for the full
load bearing weight. These struts
could weaken or fail due to wear,
environmental conditions or aging.
Operators should be aware of any decrease in effort to lift
the hood and initiate an immediate gas strut safety check.
DO NOT LIFT THE HOOD IN THIS CONDITION.
The cleanliness and appearance of
this unit will contribute considerably to
operating efficiency and savory,
appetizing food. Good equipment that
is kept clean works better and lasts
longer.
THOROUGHLY CLEAN THE DISPLAY CASE
DAILY
1. Turn lights and adjustable thermostats to the
“OFF” position.
2. Disconnect unit from power source.
3. Remove and store unused products
under refrigeration.
4. Clean the interior metal surfaces of the
cabinet with a damp cloth and any
good alkaline or alkaline chlorinated
based commercial detergent or grease
solvent at the recommended strength.
Use a plastic scouring pad or oven
cleaner for difficult areas. Avoid the
use of abrasive cleaning compounds,
chloride based cleaners, or cleaners containing
quaternary salts. Rinse carefully to remove all residue
and wipe dry.
NOTE: Never use hydrochloric acid (muriatic acid)
on stainless steel.
5. Clean glass with window cleaner.
6. 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 food service equipment.
Remember to turn power and/or breaker switch "ON"
before operating the unit.
At no time should the case
be flooded with water
or liquid solution.
NEVER STEAM CLEAN.
Do not use water jet to clean.
Severe damage or electrical
hazard could result, voiding
the warranty.
Disconnect the unit from
the power source before
cleaning or servicing.

SANITATION GUIDELINES
GENERAL HOLDING GUIDELINES
Food flavor and aroma are usually so closely related that it is
difficult, if not impossible, to separate them. There is also an
important, inseparable relationship between cleanliness and food
flavor. Cleanliness, top operating efficiency, 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 no distinction between GOOD and BAD odors. The
majority of objectionable flavors and odors troubling food service
operations are caused by bacteria growth. Sourness, rancidity,
mustiness, stale or other OFF flavors are usually the result of germ
activity.
The easiest way to insure full, natural food flavor is through
comprehensive cleanliness. This means good control of both visible
soil (dirt) and invisible soil (germs). A thorough approach to
sanitation will provide essential cleanliness. It will assure an
attractive appearance of equipment, along with maximum efficiency
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.

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 specific 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, and 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 are both cost effective
and relatively simple. While HACCP guidelines go far beyond the
scope of this manual, additional information is available by
contacting the USDA/FDA Food-borne Illness Education
Information Center at (301)504-6803.
SChefs, 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.
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.
This Alto-Shaam holding unit is is equipped with a thermostat
indicating a range of between 1 and 10. Use a metal-stemmed
indicating 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.
