General Installation
PERSONNEL
Sta who use and install the appliance must possess (or
acquire through adequate training) the following skills and
must understand the Manual instructions and all relevant
Safety information:
• General technical knowledge to understand the
Manual’s instructions
• Awareness of the main hygiene, accident prevention,
and technological regulations
PUTTING INTO OPERATION
If the equipment has been placed in a horizontal position
during transport, it cannot be put in operation immediately.
Put the unit in a vertical position, then wait about
two (2) hours to operate it.
SET UP
Initial startup requires no adjustments. If the unit was
turned o, press to turn unit on. See “Control
Operation” section for more details.
NOTICE
Temperature displayed reects actual
temperature inside unit.
If the temperature displayed is dierent than
selected, the unit is progressing towards the
selected temperature. Time to reach set point
varies based upon ambient temperature,
temperature of product loaded, door openings,
etc. U-Line recommends allowing the unit to
reach set points before loading.
To continue to set up the unit, perform the following steps:
1. Remove the packaging from the refrigerator. Assess
the area:
◦ if the vertical space is high enough, lift the box up
◦ if the vertical space is not high enough, cut away
the cardboard in sections and pull them away
NOTE: Make sure the unit stays vertical.
2. Remove the white PVC protection lm from the
stainless steel and all other protection used by the
company to reduce the risk of damage during transport
3. Place the refrigerator on a at level surface.
4. Before use, clean the refrigerator with a clean, soft
cloth and appropriate spray product.
NOTE: Use minimal water because it contains minerals
that leave traces of dirt, which are dicult to
remove.
5. Wash the tray and all internal parts, using commercial
anti‑bacterial detergents.
6. Remove the detergent with a soft sponge soaked in
water and dry with a clean, soft cloth.
NOTE: Do not use abrasive detergents or powders, which
could cover the nish with a lm.
NOTE: Use minimal water for cleaning. Too much water
can damage electric parts; a damp sponge is
sucient.
7. Install the shelf supports where needed.
8. Insert each support into the holes at the base of the
refrigerator.
9. Insert the side tab in the appropriate place on the
sides or on the table supports.
10. Slide the shelf into the supports.

THE BLAST CHILLING MODE
The Blast Chilling function allows you to quick chill food
down to 37°F (3°C), using a probe, in 90 minutes or less,
provided that:
• the total product weight matches the Blast Chiller
Specication
• the initial temperature is lower than or equal to
195°F (90°C)
• the product thickness is less than or equal to 2 inches
(5 cm)
• the food is evenly distributed in the chamber
• a pre-chill initial step is done to improve the chiller
performance in the heaviest conditions
Product temperature before and after a
Chilling Cycle
To comply with HACCP regulation, the target internal
temperature at the end of the cycle is 37°F (3°C) and
cannot be changed. The starting temperature of the food
products can vary depending on the cooking, or nishing,
process which the the food originally went through. For
example, chicken has a higher internal temperature while
pizza dough begins at a lower internal temperature.
Air Temperature
The air temperature is the temperature of the cabinet
where the food is being chilled. The range for a Blast
Chilling process is from -13°F (-25°C) to 48°F (9°C)
degrees and the holding range is from 14°F (-10°C) to
50°F (10°C).
Time or Temperature based Cycles
Use automatic (select food icons) or manual mode to
chill items. Depending on the mode and options selected,
choose to chill items by time, or by using the food probe to
set core temperature.
If time mode is selected, the Blast Chilling cycle terminates
by elapsed time. The product may or may not reach the
desired core temperature.
In food probe mode, the food probe controls the Blast
Chilling and may take more or less time. This time varies
based on the product weight, density, thickness, starting
temperature, etc., to reach the target temperature.
In either mode, after the time has elapsed or the food
probe temperature is reached, the machine switches to
hold mode automatically and maintains the product at the
storage temperature. Determine which mode you prefer,
based on your knowledge of food temperatures and the
time allotment. Select a core temperature-based cycle that
gets the food temperature to match food safety guidelines
at 37°F (3°C), before entering hold mode.
Automatic Defrost
Evaporator defrosts automatically between the chilling and
hold modes, and stops after the ice on the evaporator is
melted.

Figure 6: Food Probe Insertion Screen
NOTE: When selecting an automatic recipe, you
must use the food probe.
A time counter runs until the needle probe is inserted
in the food. The electronic system recognizes the probe
insertion and initiates the cycle (see Figure 7).
Figure 7: Cycle Initiated
The Blast Chilling in Progress screen appears. A graph
shows the food core temperatures (from the food probe)
and the air temperature in real time. The right side of the
display shows the food selected, the type of cycle (Chilling
or Freezing icon), and the fan speed. The bottom of the
display shows real time values and cycle setpoint values,
which appear from left to right:
• Food °F – Current core temperature (it takes the
warmest value)
• Air °F – Current air temperature
• Time min. – Elapsed time
• End cycle °F – Food target temperature in an
automatic recipe. When core temperature is reached,
the cycle switches to the next step

Control Operation
• Air set °F – Desired air temperature of the current step
• End cycle min. – Time the cycle will end (e.g., three
dashes indicates a core temperature-based cycle, so
time is not available)
• Food scan – Status of the four core temperatures.
The system monitors the four cores of the food thickness
in the rst ve minutes of the cycle. Cores can be excluded
from the algorithm, which means the food measured with
the excluded will not be measured. The warmest core will
determine the end of the total cycle 37°F (3°C). Each core
contributes to regulate the internal cycle’s steps, varying
the air set temperature and fan speed. The following
indicators show core status:
• Blue – Warmest core
• Green – Core is positioned in the food thickness
• Grey – Excluded core
While scanning the food, the cycle runs through four
steps with dierent settings. The goal is to chill the food
in the shortest possible time, while saving the product
integrity. For example, a piece of cooked meat with an
internal temperature of 90°C (194°F) runs through the
initial step at very low temperature. The meat reaches the
highest air temperature at the end to prevent freezer burn.
Conversely, bread is chilled at a warmer air temperature
(above the freezing point) from the start, in order to not
aect the product surface.
NOTE: Automatic OEM recipes are set up in
the factory and guarantee the best
combination of steps for a chilling cycle.
Blast Chilling Manual Program
Press the Manual button on the Food Selection screen (see
Figure 4).
The Manual Program screen appears (see Figure 8). To
set the time, press the TIME button and set the time of
the cycle. Press the AIR TEMPERATURE button to set the
cabinet air temperature. Push the FAN speed button to set
the fan speed—the default is always High or 10. Press the
HOLD TEMPERATURE button to set the temperature at the
end of the cycle. Press OK to start the cycle.

Blast Chilling Custom Recipes
Every food category (icon) allows the creation of four
custom recipes (press the Gear icon on the screen) (see
Figure 5). Custom conguration allows you to choose the
core probe option, the cycle time length (if the core probe
is not selected), the air temperature, the fan speed, and
the air temperature for the holding cycle. To disable or
enable the food probe, press the green check mark or
red X.
NOTE: Similar to the Manual Program, the custom
conguration is related to a food category
(icon).
Press the TIME (1/1440 min), AIR TEMPERATURE -25/9°C,
FAN (1–10), and HOLD TEMPERATURE -10/10°C buttons to
enter the correct values (see Figure 9).
Figure 9: Updating Values
Pressing the button for a specic mode highlights it in blue
(see Figure 10).
