Stack no more than three units one on top of another.
Gastronorm container with liquid food
Food which sloshes around and runs out of the unit can cause scalding.
Always seal Gastronorm containers filled with food with a sealing lid.
Loading
Only load the unit with Gastronorm containers or directly with hot liquid.
Gastronorm containers placed in the unit must be able to withstand a tem-
perature of at least +100 °C. Polycarbonate Gastronorm containers, for
example, may not be used.
Gastronorm containers with upright, rigid handles may not be used in the

place Gastronorm containers or other objects hotter than +100 °C in or on
the unit, e. g. Gastronorm containers heated in a combination steamer.
Tension fractures caused by cold water in hot stainless-steel
basins
When cold water is poured into hot stainless-steel basins, the rapid change
in temperature can cause microscopic tension fractures. These, in turn, can
lead to corrosion. Before filling with cold water, allow stainless-steel basin to
cool down, or fill the hot stainless-steel basin with hot water.

Operation
If the unit is operated with the cover open for an extended period, a large
amount of heat is lost. Operate the unit only with the cover closed. A unit con-
nected to the power supply may only be opened briefly to place food inside
or to remove food.
Do not operate external heat sources inside the unit.
Do not put an open flame inside the unit.
The unit cover does not seal completely when closed. If sealed completely, a
vacuum would be created inside when cooling, and it would be impossible to
remove the cover.
As the cover does not seal completely, hot steam can exit the unit during
temperature maintenance of food. Danger of scalding!
Change of location
The unit can be heavy when loaded (up to 45 kg). Lifting heavy loads can
cause injuries. This applies in particular for people who already have weak-
ened musculoskeletal systems.
To minimize danger to your health, always lift the unit with a second person.
If possible, use suitable equipment to lift the unit.
Lift and carry the unit with the carrying handles only, never use the locking
levers for this purpose. If the unit is lifted or carried via the locking levers, the
cover can open and the bottom section of the unit can drop.
The unit cover does not seal completely when closed. If sealed completely, a
vacuum would be created inside when cooling, and it would be impossible to
remove the cover.
As the cover does not seal completely, extra caution is advised with wet load-
ing or direct loading with hot liquid. When lifting and carrying the unit, hot
steam or hot liquid could exit between the rim of the stainless-steel basin and
the cover and cause scalding.
It is especially dangerous when one person carries the unit in front of his/her
body using both hands. If the unit is tilted toward a person's body while it is
being lifted up, set down or carried, hot liquid can exit and cause scalding.
If possible, wait to fill the unit with liquid until it is at it's intended location.
Move the unit while upright, preferably with two people.
Secure units stacked one on top of another from tipping before changing
their location.
If a portable support (e. g. transport cart) is used to change the location of a
unit or max. three stacked units, all possible measures must be taken to
prevent damage to people and objects. This includes the following, among
others:
yDo not exceed the maximum loading capacity of the support
ySecure the unit(s) to the portable support so that they cannot tip over
yAlways move the unit(s) with two people
yOnly sloping surfaces with an incline < 10° may be crossed
ySecure the unit(s) from rolling away accidentally
The skids on the unit are worn down when it is moved directly on the floor.
To prevent the skids from wearing down, do not pull or push the unit directly
on the floor.
The edges and corners of the plastic body can be damaged by forceful
impacts. Water can seep into the unit walls in this case, especially when
cleaning in a dishwasher. The water which seeps in can cause irreparable
damage to the heater. Always handle the unit with care. Avoid impacts.

)With the BLANCOTHERM 320 KB, the setpoint temperature is fixed at
+90 °C. Instead of the temperature display and buttons, these units fea-
ture a film layer with an operation indicator LED. This LED illuminates con-
tinuously as long as the unit is connected to the power supply.

Loading types - Overview The unit can be loaded in the following three ways:
Dry loading with Gastronorm containers
yGastronorm containers are hung in the dry stainless-steel basin
yWhen filling with a small amount of food, we recommend preheating the
unit
Procedure for dry loading:
ªSection "Dry loading the unit" on page 17.
Wet loading with Gastronorm containers
yGastronorm containers are hung in the stainless-steel basin which con-
tains four liters (specified fill amount) of hot water
yWhen loading with a small amount of food, we recommend preheating
the unit
yAdvantages of wet loading:
– High level of heat transfer to the Gastronorm container(s) via hot steam.
– The water is a good heat reservoir.
– BLANCOTHERM 320 KBR: The temperature distribution in the unit is
more even than with dry loading. The temperature regulator functions
more precisely here.
Procedure for wet loading:
ªSection "Wet loading the unit" on page 19.

Direct loading into the stainless-steel basin
yThe stainless-steel basin is filled directly with hot liquid food or with hot
water into which food (e. g. hot dogs) will be placed
yFood loaded directly into the unit is heated to the fixed specified temper-
ature (BLANCOTHERM 320 KB) or the set temperature
(BLANCOTHERM 320 KBR). This must be taken into account with sen-
sitive foods (e. g. sausages)
yThe liquid must be hot when filled in, as the unit was not designed to heat
up a large amount of water
yAs the unit must be filled with hot food or liquid, preheating is not
necessary
Procedure for direct loading:
ªSection "Direct loading the unit" on page 21.
)With direct loading, salt and other substances come into direct contact
with the stainless-steel basin. Contact with these substances can cause
very light corrosion. For this reason, the stainless-steel basin must be
cleaned very thoroughly after being used for direct loading and must then
be rubbed dry.
Displaying the setpoint
temperature
BLANCOTHERM 320 KBR
IThe temperature range of the temperature regulator lies between +40 °C
and +95 °C. The maximum temperature (approx. +98 °C) is reached in
the unit in "Full Power" mode (FP). "Full Power" mode is the factory set-
ting of the unit.
Connect the unit to the power supply.
ªSection "Connecting the unit" on page 9.
The temperature display performs a LED self-test and temporarily dis-
plays 88 .
The temperature display then switches to the actual temperature.
A dot LED to the right of the second temperature-display digit indicates
that heating is active.
To display the setpoint temperature, briefly press any button at the tem-
perature regulator.
The setpoint temperature is displayed. FP indicates "Full Power" mode,
i. e. the maximum setpoint temperature.
The display automatically switches back to the actual temperature a few
seconds later.

Setting the setpoint
temperature
BLANCOTHERM 320 KBR
)The lowest temperature setting is +40 °C, and the highest FP
(Full Power), which corresponds to a temperature of approx. +98 °C.
)While the setpoint temperature is being set, the unit switches off heating
automatically. The dot LED to the right of the second temperature-display
digit does not illuminate. When the setpoint temperature is set, heating
switches on automatically if the actual temperature is too low.
9Unit is connected to the power supply
To lower the setpoint temperature, press the "down" button briefly sev-
eral times in succession.
After the first press, the setpoint temperature is displayed (FP indicates
"Full Power" mode). Each subsequent press reduces the setpoint tem-
perature by 1 °C.
– or –
Press and hold down the "down" button.
After approx. 1 second, the temperature setting changes continuously.
To raise the setpoint temperature, press the "up" button repeatedly.
After the first press, the setpoint temperature is displayed (FP indicates
"Full Power" mode). Each subsequent press increases the setpoint tem-
perature by 1 °C.
– or –
Press and hold down the "up" button.
After approx. 1 second, the temperature setting changes continuously.
When setting is complete, wait until the temperature display switches to
the actual temperature.
The last setting of the setpoint temperature is saved automatically.
IThe unit continuously saves the setpoint temperature. If the voltage sup-
ply is interrupted, the last set setpoint temperature is active.
IIf the voltage supply is interrupted while a new setpoint temperature is
being set, the previous setpoint temperature remains unchanged. The
unit saves a new setpoint temperature when the temperature display
returns to the actual temperature.
