CARE and CLEANING
EXAMPLE
S E R I A L N U M B E R A N D WA R R A N T Y C O D E
MODEL
The oven is equipped with a special, high-heat-density, heating
cable. Through the Halo Heat concept, the heating cable is
mounted against the walls of the cooking cavity to provide an
evenly applied, thermostatically controlled, heat input. The design
and operational characteristics of the unit eliminate the need for a
moisture pan and/or heat circulating fan. Because of the even heat
application, the quality of a food product is maintained for long
periods of time. The actual time depends on the type and quantity
of product.
If necessary a proper outlet configuration, or permanent
wiring for this oven must be installed by a licensed electrician
in accordance with applicable, local electrical codes.
Never flood this oven
with water or liquid solution.
Do not use water jet to clean.
DO NOT STEAM CLEAN.
Severe damage or electrical
hazard could result, voiding the
warranty.
Clean and install the oven side racks, oven shelves and drip pan.
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.
CLEAN THE OVEN DAILY.
1. Disconnect the oven from the power source.
2. Remove all detachable items such as shelves, side
racks, and drip pans. Clean separately.
3. Clean the interior metal surfaces of the oven
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.
4. To help maintain the protective film coating on polished
stainless steel, clean the exterior of the cabinet with a cleaner
recommended for stainless steel surfaces. Spray the cleaning
agent on a 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 equipment.
NOTE: The electronic control of the oven is designed to be water
resistant; but remember this is an electric appliance,
and electrical hazard or damage could result if this area is
steam cleaned or flooded with liquid.

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 foodborne illnesses. Temperature monitoring and control during
receiving, storage, preparation, and the service of foods are of
equal importance.

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 Foodborne Illness Education Information Center at (301) 504-6803.
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.
Most Halo Heat Holding Equipment is provided with a
thermostat control between 60° and 200°F (16° to 93°C). If the unit
is equipped with vents, close the vents for moist holding and open
the vents for crisp holding.
If the unit 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.

TROUBLE SHOOTING GUIDE
OVEN TEMPERATURE CALIBRATION
The oven thermostat is part of the electronic computer control,
and is a precise instrument, therefore, no specific thermostat
calibration is ever necessary. If you suspect the oven does not
match the set temperature, check the ambient (air) temperature
within the oven cavity with a quality thermal indicator.
• With the exception of the two (2) oven side racks, the
three (3) wire shelves and the drip pan, empty the
oven cavity.
• Place the thermal indicator in the center of the oven cavity.
• Check to make certain the unit voltage matches the power
source.
• Make certain the oven sensor, located inside the oven
cavity at the back of the unit, is clean.
• Allow at least one (1) hour for the cavity temperature to
stabilize before reading the cavity temperature on the
thermal indicator.
• If the reading are substantially correct (NEVER OVER
15 Amps) replace the Circuit Breaker/Power Switch.
CHECKING/REPLACING HEATING ELEMENT
1.
2.
Check continuity, from each element to ground, with a
quality ohm meter. There should be no continuity. If there
is continuity, replace the element.
Check the resistance of each element:
• High Temperature Element: .
66 ohms/foot (2.17 ohms/meter)
•Approximately 20-24 ohms per length for 125 volt units
•Approximately 40-44 ohms per length for 208-240 volt units
If the resistance is very high or low, replace the element. When
replacement of the element is required, complete instructions will
be provided with shipment of the replacement element.
NOTE: In the event only one element requires replacement,
CHECKING/REPLACING PROBE or SENSOR
The probe and oven sensor are mounted on the inside back of the
oven cavity. There is an access cover to the probe and sensor
wiring hook-up at the same approximate location on the outside
back of the unit. To check the probe or sensor, take a resistance
reading with a quality ohm meter, on the low ohms scale. The
reading, with the oven at room temperature, should be between
100 and 120 ohms. If the resistance is higher or lower, the probe
or sensor requires replacement. Insure good connections when
replacing the probe or sensor. In addition to using the wire nuts,
solder all connections.
CHECKING/REPLACING CONTROL COOLING FAN
If the Cooling Fan is not operating, initially check to make certain
it is receiving power from the Cooling Fan Thermostat. The
Cooling Fan Thermostat is located on the outside top of the oven
cavity.
NOTE: The Cooling Fan does not operate until the oven
cavity temperature reaches at least 140°F (60°C).
If the fan is receiving power but is still not operating,
replace the Cooling Fan. When replacing the Cooling Fan,
insure that the fan is positioned to blow air
INTO the control cavity.
CONTROL COOLING FAN THERMOSTAT
The Cooling Fan Thermostat should close (ON) when the oven
cavity reaches approximately 140°F (60°C) and open (OFF) when
the oven cavity decreases to room temperature. Replace if needed.
BEEPER
The Beeper is located inside the control cavity, on the bottom.
Check the wiring to the Beeper. If the wiring is good and all other
aspects of the control function properly, replace the Beeper.
CIRCUIT BREAKER/POWER SWITCH
If the Circuit Breaker/Power Switch trips:
• Check the unit thoroughly for possible shorts.
• Test the current draw with a quality amp meter.
• Compare the readings with the electrical ratings
located elsewhere in this manual.
check the remaining elements for any deterioration and
replace at this time.
CONTROL REPLACEMENT PROCEDURES
Before attempting to replace the control, make certain the
problem is in the control and not in the oven. Thoroughly check
the oven for ground faults, shorts, etc.
The control can be replaced from the front of the unit. The
chrome retaining ring, around the control panel, is removed by
removing two (2) screws at the bottom of the ring. Lift the
chrome retaining ring up and off the control panel. (The retaining
ring is hooked at the top of the control panel.) Slide the control
forward until the top of the control can be pivoted out and down.
The body of the control is fastened by two studs which will hold
the control in place, while disconnecting the wiring.
Label each control wire BEFORE disconnecting, to insure each
wire will be connected to the correct terminal point on the
replacement control. When all wires are removed from the
control, pull the control out of the unit by aligning the studs on
the control with the slots in the control opening. Insert the
replacement control and attach all wires according to the labels.
Align the new control between the retaining projections and fully
insert in the unit. Hook the chrome retaining ring to the top of
the control panel and secure at the bottom of the control panel
with the two (2) screws.
Check the new control system by operating the oven according to
the standard Operating Procedures located elsewhere in this
manual.
CHANGING FROM °F MODE TO °C MODE
Remove the top of the unit and locate the slide switch at the top of
the control. This is the °F to °C Conversion Switch. Slide the
switch to the position desired.
When in the °F position, the oven controls must be set with °F
temperatures (within °F parameters). The Digital Display will
show only °F temperatures.
When in the °C position, the oven controls must be set with °C.
Temperatures (with °C parameters). The Digital Display will
show only °C temperatures.
