SECTION 3. OPERATION
3-1. INTRODUCTION This section provides the daily operating procedure for the
heated merchandiser . Read this section thoroughly before
operating the merchandiser.
3-2. ST ART-UP
1. Turn the POWER and HEAT switches to the ON position.
2. Fill water pan assembly (inside the well area) with about 1.5
gallons (5.7 liters) of water. This should provide approximately
8 hours of humidified operation under normal circumstances.
3. Allow approximately 30 minutes preheat time before placing
product into the merchandiser.
4. The lower heat controls are located above the far left well of each
full-serve section, along with the upper heat controls for that well.
The air temperature is shown at all times and can be changed by
using the UP and DOWN buttons. The temperature range is
140º-180º F (60º-82º C).
T o check the actual air temperature, press the button marked
“Press to view Actual T emp.” Also, if the controls are
locked, the
controls cannot be changed until the controls are unlocked. See
Special Programming section.
5. The upper heat controls (radiant heat), are located above each
well and can be individually set depending on the types of food
that are being held in each well. The upper heat setting is shown
at all times, and can be changed from settings of 1 to 10, by using
the UP and DOWN buttons.
The upper heat settings read 1, 2, 3, etc. One meaning the heat is
on 10% of the time, 10 meaning the heat is on 100% of the time.
Settings of 9 and 10 have been designed for use when the rear
doors of the unit have been removed. Use of these settings with
the doors in place is not recommended.
6. As a rule, a lower radiant heat setting, such as 3 or 4, holds
dense foods like macaroni and cheese or cherry cobbler. Use
higher upper heat settings for less dense foods, such as fried
chicken.

3-3. OPERA TION WITH
PRODUCT
7. The water (humidity) temperature controls are located above the
water pan of each full serve section. If humidity is desired in the
merchandiser, press the button marked ON to activate the water
pan heater . If “Add H2O” flashes in the display, water needs to
be added to the water pan. If no humidity is desired, press the
OFF button so the water pan heater does not come on.
T o prevent a false “Add H20” code, make sure the water pan is
touching the operator side of the unit, inside the well area.
8. T o use a food temperature probe to monitor food, plug the probe
into a receptacle located above each well inside the unit. Place
the probe into the food, and press the probe button to toggle
between showing the probe temperature and upper heat setting.
1. Rotate food from front to back.
2. Food in half-size pans does not hold as well as food in full size
pans. Rotate pan to back of merchandiser where it is directly
under upper heating elements or move food to a smaller pan that
has been preheated.
3. When freshening foods such as macaroni and cheese with
added water, heat the water in a clean container until it is 10º F to
20º F (6º C to 12º C) above the desired holding temperature of
the food. This will keep food at a safe serving temperature.
Depending on the amount of water, the temperature can drop
10º F to 20º F (6º C to 12º C) in as little as five minutes.
4. When transferring hot foods in the heated merchandiser to clean
pans, preheat the clean pan. Transferring hot foods to room
temperature pans can cause the temperature of the food to drop
20º F (12º C) or more, thus causing food to be at an unsafe
serving temperature.
5. If operating unit with rear doors removed, it is recommended that
third size pans be placed in the center section of the well for
optimal holding. Food temperatures will be maintained for up to
an hour with doors removed and upper heat set to 9 or 10.
Remember to frequently monitor food temperatures.

PRODUCT (Continued)
3-4. SHUT DOWN AND
CLEAN UP
6. T o keep hot foods from drying too fast, keep a clean misting
bottle (such as you find in a garden supply store) with a mixture
of 1/3 vegetable oil and 2/3 water on hand. Set the nozzle for a
fine mist. Shake the vegetable oil and water mixture well. Spray
surface of food immediately , shaking the bottle between each
entree. The frequency with which the foods need to be misted
depends upon the unique characteristics of the food, the water
heat setting in the case and atmospheric conditions. Do not use
this mixture on foods with a pastry crust or crumb toppings
where a dry surface is desirable.
7. If prepackaging foods, place containers directly under
upper heating elements (in back of the case) for maximum
holding time. Upper heat may need to be increased
slightly .
1. Remove all power from the unit by unplugging the unit
from the wall receptacle, or by turning off the wall circuit
breaker.
2. Allow unit to cool before cleaning.
3. Remove rear doors and open front glass.
4. Remove pans, pan supports, and water pan and clean with
soap and water at sink.
5. Clean all surfaces with a soft cloth, soap, and water.
Do not use steel wool, other abrasive cleaners or cleaners/
sanitizers containing chlorine, bromine, iodine or ammonia
chemicals, as these will deteriorate the stainless steel
material and shorten the life of the unit.
Do not spray the unit with water, such as, with a garden
hose. Failure to follow this caution could cause component
failure.

3-4. SHUT DOWN AND
CLEAN UP (Continued)
6. Clean around electrical controls and components with a
damp cloth.
7. Clean doors and glass with a non-streaking liquid glass
cleaner .
Do not use abrasive cleaners or scratches to the glass
may occur.
8. Leave doors open until ready to load and use again.
Cleaning Non-Glare Glass. Use a soft cloth, or sponge, and a
non-abrasive cleaner and water. Dishwashing liquid, or similar
product works well. When cleaning the inside of cases, it is recommended the doors be completely open and covered to prevent
splashing onto the glass, and ruining the glass coating.
Do not use steel wool, scouring pads, cloth with metal
thread, scrapers or other sharp tools, alkaline or acidic
cleaners/sanitizers or cleansers containing flourides, as
these will damage the coated surface of the glass.

3-5. LIGHT BULB REPLACEMENT
Model HMR-103,104,105,106,107
T o avoid electrical shock or pr operty damage, move
the POWER switch to OFF and disconnect main
circuit breaker, or unplug cord at wall receptacle.
Light bulbs and glass may be hot. Severe burns could
result.
1. Raise the glass canopy and ensure that the gas shocks
support its weight before proceeding.
Figure 1
Figure 2
Do Not attempt to access the bulb from the operator’s
side of the unit. The installer cannot easily see the bulb
and socket or the adjacent radiant heaters, increasing the
potential shock or burn hazard.
2. Carefully remove the old bulb and discard. Figure 1.
3. V isually inspect socket to ensure there is no debris or damage
that may impede bulb installation. Figure 2.
4. Install the replacement bulb. Tighten using a gentle pressure.
To help prevent a short bulb life:
•
Do not over-tighten the bulb. Over-tightening will
damage the contact end of the bulb and compress the
contact tab in the socket.
•
Do not install the bulb with the power on. During normal
operation, the socket is exposed to various food related
agents, such as moisture and gr ease. When installing a
new bulb with the power on, the spark that occurs when
the bulb contact touches the socket, places a deposit on
the bottom of the bulb. This deposit results in a higher
amp draw and shorter bulb life.
