Time and Temperature Guidelines
To assure quality and safety in chilled processed food
handling, it is important to observe the following
1.Prechill refrigerated cart for 30 minutes before
adding food.
2.All foods must be covered prior to chill or freeze
3.Food temperature will reduce from 140°F to 40°F
(60°C to 4°C) within 4 hours.
4.Do not remove food from chiller until it reachs a
temperature of 40°F (4°C) or lower.
5.Chilled foods must be stored under refrigeration
designed to hold products at 34° to 38°F (1° to 3°C)
for a maximum of 5 days. A 5-day shelf life includes
the day of production and the day of consumption.
To maintain sanitation control, all foods
for quick-chill or quick-freeze processing
must be at a temperature above 140°F
(60°C) and must be tightly covered.
Adequate spacing must be allowed between pans for
proper air circulation for both processing and subsequent
holding. Stacked pans will restrict air flow and increase
chill processing time.
6.Cooked food that has been chilled must be reheated
to a minimum core temperature of 165°F (74°C)
before serving. Refer to local food codes for possible
7.Always reference and adhere to local food codes
and HACCP guidelines with regard to time and
temperature for chilling or frozen food processing.
MN-36246 • Rev 3 • 03/17 • 1000-MR2 Refrigerated Carts
Product Covering
Portioning and Packaging
To maintain sanitation control when loading the
refrigerated cart, foods must be above 140°F (60°C) and
should be tightly covered. A tight cover is an important
part of proper chilling methods and must be used to
prevent the possibility of accidental contamination by
airborne bacteria.
1.During portioning and packaging operations, all
foods should be maintained at or above 140°F (60°C),
or below 40°F (4°C).
Stainless steel pan covers may be used. Stainless steel
covered pans must include a label indicating pan
contents and use-by date. A cover of clear plastic wrap
is also acceptable.
When using plastic wrap as a food covering, make
certain the wrap comes in direct contact with the
surface of the product and extends around and down
each side of the pan. This is an important step to ensure
proper chilling times. Spacing left between the plastic
wrap and the surface of the food creates an insulating
air gap resulting in more product heat retention and a
slower chilling rate.
Meat roasts and other larger, dense products should be
no larger than a weight of 8 to 10 pounds (4 to 5 kg) per
item. Because of the density of these products, chilling
could take up to 4 hours. Due to longer chilling time
required, it is also suggested these items be chilled at
the end of the day with the chiller set in the automatic
chill/hold mode. This method provides the operator
with fully chilled product holding at a refrigerated
temperature on the following day.
Prior to chilling, roasts must be wrapped in clear plastic
and placed in the chiller. Do not slice roasted meats
until the day of service.
Portioned meat products such as pork chops or meat
patties should be chilled directly on the sheet pans
on which they were cooked. Cover the sheet pans
with clear plastic wrap for chilling. After chilling, this
type of product can be placed in steam table pans for
refrigerated storage.
2.If cooked foods exceed the processing capacity
of the refrigerated cart, place hot product in an
appropriate back-up hot holding device. Hold hot
foods at a temperature above 140°F (60°C).
If a hot food holding cabinet is not available, place
hot foods in short-term refrigerated storage until
these products can be loaded into the refrigerated
cart for the next available processing cycle.
Production of cooked foods should not exceed the
processing capabilities of the chiller, therefore,
do not adopt short-term refrigeration as a routine
practice but use only in an emergency situation.
3.Fill containers to a 12 pound (5 kg) limit or
maximum depth of 2" (51 mm) of product. Do not
use plastic or Lexan® containers.
4.For faster cooling, place lids and over-wrap
materials directly on the surface of foods. As
previously indicated, air trapped between the lid and
food surface acts as an insulator and will increase
chill time.
5.For faster chilling times, place low profile foods such
as chicken quarters, fish fillets, or ribs in low depth
containers such as 1-1/2" (38mm) deep sheet pans.
6.Large cuts of meat and poultry that weigh a
maximum of 8 to 10 pounds (4 to 5 kg) should be
individually wrapped with tight fitting film and
placed on sheet pans in the chill cabinet.

Food Safety
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, operating efficiency, and
appearance of equipment contribute considerably to savory,
appetizing foods.
Most food imparts its own particular aroma and many
foods also absorb existing odors. Unfortunately, during
this absorption there is not a 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
undesireable flavors are usually the result of germ activity.
The easiest way to ensure 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 ensure 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 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 food temperatures from the time the
food is received through the time the food is served.

assure food integrity, quality, and safety. Taking steps
necessary to augment food safety practices is both
cost effective and relatively simple. Additional HACCP
information is available by contacting:
Center for Food Safety and Applied Nutrition

Phone: 1-888-SAFEFOOD
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 thermometer is an effective tool for this
purpose, and should be routinely used on all products that
require holding at a specific temperature.

Cleaning and Preventative Maintenance
Protecting Stainless Steel Surfaces
Cleaning Agents
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.
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. Failure to observe
this precaution will void the warranty. Always use
the proper cleaning agent at the manufacturer's
recommended strength. Contact your local cleaning
supplier for product recommendations.
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 per day. Always thoroughly
rinse surfaces after using a cleaning agent and wipe
standing water as quickly as possible after rinsing.
e b r us
t e el p ad
w ir
s c r a p er
To protect stainless steel surfaces,
completely avoid the use of abrasive
cleaning compounds, chloride based
cleaners, or cleaners containing
quaternary salts. Never use hydrochloric
acid (muriatic acid) on stainless steel.
Never use wire brushes, metal scouring
pads or scrapers.
Cleaning Materials
Cleaning can usually be accomplished with the
proper cleaning agent and a soft, clean cloth. When
more aggressive methods are needed, use a nonabrasive 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. Failure to observe this precaution will void
the warranty.
To prevent serious personal injury, death,
or property damage:
The appliance must be cleaned thoroughly
to avoid deposits of grease and or food
residue inside the appliance that may
catch fire. If fat deposits and/or food waste
inside the appliance ignite, shut down
the appliance immediately and keep the
appliance door closed to extinguish the
fire. If further extinguishing is required,
disconnect the appliance from the main
power and use a fire extinguisher (do not
use water to extinguish a grease fire!).

invalidates the warranty and relieves
Alto-Shaam of all liability.

Cleaning and Preventative Maintenance
To prevent serious injury, death, or property
damage, always disconnect the appliance
from the power source before cleaning
or servicing.
How to Clean the Interior
1.Disconnect appliance from power source.
2.Wipe the interior cavity with a clean cloth to remove
loose food debris.
3.Clean the interior with a damp clean cloth or sponge
and any good commercial detergent.
Wipe the interior door panel and clean the vinyl
gaskets. Make certain to clean under the gaskets to
remove any mildew accumulation or food residue.
4.Rinse all interior surfaces by wiping with a sponge
and clean warm water.
5.Remove excess water with a sponge and wipe dry
with a clean cloth.
6.Wipe interior surfaces with a clean cloth and
sanitizing solution for use on metal and vinyl food
contact surfaces. This is an important step to control
the build-up of unwanted mildew and mold in the
refrigeration system.
7.Allow interior to air dry with door open.
How to Clean the Exterior
To prevent serious personal injury, death, or
property damage:
Do not steam clean, hose down or flood the
interior or exterior with water or liquid solution
of any kind. Do not use water jet to clean. Failure
to observe this precaution will void the warranty.
How to Clean the Condenser
All the heat removed from the cabinet is discharged
into the room via the condenser which is similar to a car
radiator. This must be kept clean so that the air can pass
through it to remove the heat, if it becomes choked with
dust the unit will over heat and this can lead to a burnt
out compressor. The condenser should be brushed with
a soft brush to remove any dust deposited on the alloy
fins. The frequency of this cleaning is determined by
the amount of dust in the surrounding area but should
be cleaned at least 4 times a year.
How to Replace the Door Gasket
Damaged gaskets can easily be replaced. Remove the
old gasket by gently pulling it out of the gasket retainer
and simply push in the new gasket leaving the corners
to last.
1. W
ipe all exterior surfaces
including the control panel,
door frame, latches, and hinges
with a damp cloth containing a
mild, non-abrasive, non-chloride
detergent solution.
2. R
inse detergent solution with a cloth and warm
water. Allow exterior to air dry.
3.Polish with any standard stainless steel polish
designed for use on food service equipment.
When cleaning the exterior of the cabinet, always
wipe with the grain of the stainless steel to avoid
scratching or marring the finish.
NOTE: Do not use abrasive cleaning compounds or

The controller is equipped with internal visual and audio alarms:
Press any button on the controller to silence an alarm. Verify that the
indicator is lit. If lit, verify that the door
is closed and the gasket is sealing correctly. Also, check that the condenser is not choked and that the condenser and
evaporator fans are running. If the evaporator is iced up, press and hold the
