HN2 & HN2SYS Series Operation & Care Manual • 8
1. DO NOT ADD WATER TO DISPLAY CASE
Halo Heat display cases maintain a constant but
gentle temperature and eliminate much of the
moisture loss associated with conventional display
cases. Because of this gentle heat, it is not necessary
to add water to the display case. As a matter of fact,
a dding water is not recommended since water will
accelerate the deterioration of the product, and may
damage the unit voiding the warranty.
2. PLACE DIVIDERS AND SERVING
PANS IN CASE
Refer to the pan layout diagrams for different
types of pan accommodations. A complete pan
configuration layout is located in this manual. It
is VERY important to note, no matter what type
of pan configuration chosen, 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. If these gaps
are not closed, heat will escape from the bottom of
the case into the display area. As a consequence,
heat distribution will be uneven and uniform
temperature will be difficult to hold. If needed,
additional pan divider bars are available. The
supplied self-serve pan inserts with wire grids are
for use with pre-packaged foods in the self-serve
sections of the units.
3. TURN DISPLAY LIGHTS “ON” AND SET
THE THERMOSTAT(S) AT NUMBER “10”
TO PREHEAT
A indicator light will illuminate when the
thermostat(s) is (are) turned “ON.” The
indicator(s) will remain lit as long as the unit is
preheating or calling for heat. The unit should be
preheated at the 10 setting for a minimum of
30-45 minutes before loading the case with hot
food. When preheating is completed, or whenever
the unit reaches any temperature set by the
operator between 1 and 10, the indicator light(s)
will go “OUT”.
4. LOAD HOT FOODS INTO DISPLAY CASE
Be certain only hot food is transferred into the
display case. Before loading food into the case,
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.
Use hand protection when handling hot items.
Be certain only hot PREPACKAGED foods in
appropriate heat tested containers are used in
the self-service section of the display case.
Do not stack food containers.
5. RESET THERMOSTAT(S) AS NEEDED
After all products are loaded into the display case
and the doors are closed, it is necessary to reset
the thermostat(s). For fully enclosed sections, reset
the thermostat to the number “8” setting. Cases
with a self-service section should be maintained
between number “9” and number “10” for the
self-service section only. THESE SETTINGS WILL
NOT NECESSARILY BE FINAL. 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 a minimum
of 140° and 160°F (60° and 71°C). Normally, this
will require a thermostat setting of between
number “6” and “8” in fully enclosed cases. Self-
service cases or sections will always require a
higher thermostat setting.
6. PLACEMENT OF FOOD PROBE
If the unit is equipped with the probe accessory,
wipe each probe and probe tip with a disposable
alcohol pad to clean and sanitize before using. If
the probe is left in its bracket, the LED
temperature display will indicate the ambient air
temperature inside the case. To place a probe into
food kept in the case, remove the probe from the
bracket and push the probe tip halfway into the
product, positioning the tip at the center of the
food mass. If placing into solid foods such as
meat roast or poultry breasts, push the probe in
from a straight downward position or in from the
side to the center position. If placing into a
semi-liquid or liquid product, the probe cable will
probably need to be secured to keep the probe
positioned properly. Do not let the probe tip
touch the edges or sides. Tape the probe cable to
the lip or edge of the container. Wipe each probe
tip with a clean paper towel to remove food debris
after each use. Follow by wiping probes with a
disposable alcohol pad, and return each probe to
the proper bracket position.
7. SERVE FRESH HOT FOOD
Keep hot foods looking fresh. Occasionally stir
or rotate food as needed. Serve food products in
appropriate heat tested packages or containers.
Keep display case doors closed after serving.
Wipe spills immediately to assure maximum eye
appeal and to ease end of the day cleanup.
