5. Packing
The packaging of your LELIT coffee machine has been studied and produced
to be re-used. Use the original box and all the packaging elements in case you
need to send the machine back to your reseller or to an authorized service cen-
tre, for ordinary or extraordinary maintenance. On our YouTube channel you will
nd a video on how to pack the machine properly, using the original box and
packaging material. Please also consult your LELIT reseller before shipping the
machine away and follow his eventual specic instructions.
6. First start-up
6.36.1 6.2
FRONT
Attention. Remove the machine from its packaging and follow the instruc-
tions printed on the box.
Attention. The unit weighs 26.5 kg
Place the machine on a solid, at, and dry surface and make sure the appliance
is stable; if needed, screw/unscrew the feet to adjust the position of the machine.
Fill the water tank (2) with room temperature water up to the indicated maximum
level and insert it in its seating (Pic 6.1).
Note. The machine has been designed to be also connected directly to the
water mains (see accessories in the equipment box). For this type of connection,
we recommend contacting an authorized technician.
Attention. Make sure that the paddle (9) is positioned completely to the
right to allow the passage of the water. The group lever (13) has 2 functional
positions: completely up for open and completely down for closed. Make sure
that the group lever is completely down.

11
Extended guide
Use the power cord (L) to connect the machine to the electrical mains and turn
ON the machine by pressing the ON/OFF switch (6) (Pic 6.2). Once the display
shows the LELIT logo, follow the instructions that appear on the LCC (7): lift the
group lever (13), wait for the countdown (30 seconds) to nish and return the
group lever (13) in its original position. Wait until the bar is fully loaded and “OK”
appears on the display (less than 24 minutes).
The hydraulic circuit will need maximum 4 minutes from the 1st turn on to get
lled with water.
Now the hydraulic circuit is lled up. The machine will start heating the water to
reach the pre-set values. This operation requires maximum 24 minutes.
Note. It may happen that the LCC (7) shows to rell the water tank. Follow
the instruction to ll the hydraulic circuit correctly.
Once the water temperature has reached the pre-set values and the hydraulic
circuit is lled up, the LCC (7) will show the temperature inside the coffee boiler
and a coffee cup icon (Pic 6.3).
Attention. During the heating phase, a small quantity of water and steam will
drain in the tray (16). This is normal and conrms the machine correct functioning.
7. Connection to the water mains
The LELIT Bianca can also be connected to the water mains. The equipment
box contains the necessary components, but we suggest you contact a special-
ized technician for this operation and follow the instructions supplied with the
machine, our technical sheet #7900190 (inserted in the equipment box with the
pieces for the connection).
The water prole used with the coffee machine is a very important factor, and it
inuences the result in the cup and the machine performance in time. Below you
can see the prole that we suggest for a good and stable extraction:
Parameter Range
Chlorine (ppm Cl2) 0
pH 6,5 - 7,5
Total Hardness (ppm CaCO3) 0 - 110
Carbonate Hardness (ppm CaCO3) 40 - 75
Chloride (ppm Cl-) < 30
Sulphate (ppm SO4) < 50

Attention. Before installing the water softener lter (M), follow the instruc-
tion for the rst start-up of the machine. The hydraulic circuit must be lled up.
Before installing the water softener lter in the water tank, immerse the lter (M)
in a jug full of water for about 3 minutes to eliminate the air inside the lter that
may cause a machine disfunction (Pic 8.1).
Take out the water tank (2) and remove the black plastic support placed on the
bottom of the tank. Insert the lter (M) in the bigger hole of the support, remove the
charge tube from the small plastic lter and x it on the nozzle of the lter (Pic 8.2).
Re-place the support in its seating on the bottom of the tank (2), rinse the tank
carefully, ll it with water and insert the tank in its seating (Pic 8.3).
9. Espresso and coffee

Extended guide
Choose the coffee lter (a,b,c), insert it into the lterholder (F) and ll it with ad-
equate quantity of ground coffee. Use the tamper (J) to press the coffee powder
in the lterholder. Fix the lterholder into the brewing group (8) and make sure
the handle is aligned with the padlock symbol present on the group (Pic 9.1).
Place the cup/s under the lerholder (F) and lift the group lever (13) to start
brewing (Pic 9.2).
Attention. Make sure that the paddle (9) is positioned completely to the
right to allow the passage of the water.
9.4
OK
By turning the paddle (9), you can change the water
ow, hence the pressure, on the coffee to obtain the
desired extraction prole. The pressure value will
be shown on the manometer (11) (Pic 9.3).
Return the group lever (13) to its initial position to
stop the extraction (Pic 9.4).
Take out the lterholder (F) and empty the lter after
every coffee extraction.
Note. We suggest you leave the lterholder inserted into the brewing group
to help harmonize the temperature between the group and the lterholder com-
plete of the lter.
Attention. Do not remove or loosen the lterholder from the brewing group
during the coffee extraction to avoid burn risks caused by hot water leaks.
Note. If you want to track any thermal uctuations, press twice the but-
ton while the lever is lifted to show the temperature of the coffee boiler during
extractions.

LELIT Bianca - PL162T
10. Steam and hot water
10.1 Steam. Open the steam knob (4) by turning it anti-
clockwise (Pic 10.1), with the steam wand (5) point-
ed on the drip tray (16), to drain the small quantity of
water.
When the steam comes out close the knob (4).
Place the milk jug, lled up to the beginning of the
spout, under the steam wand (5) and open again
the steam knob (4).
Once you have obtained the desired result, turn the
knob (4) clockwise to stop the function.
Attention. Clean the steam wand (5) after every use by pointing the steam
wand to the drip tray (16) and dispensing some steam. Thoroughly clean the
wand (5) with a sponge or clean cloth.
10.2 Hot water. Place a jug under the hot water wand
(12) and open the hot water knob (10) by turning it
anticlockwise (Pic 10.2).
Once you have obtained the desired result, turn the
knob (10) clockwise to stop the function.
Attention. Never place hands or other body parts under the steam (5) or hot
water (12) wand. Burn/Scald risks.
11. Energy saving modes
LELIT Bianca has multiple states that can be activated and deactivated to match
your routine with the minimum energy consumption possible.
All in all, what LELIT Technical Department and Lab suggest is to follow what is
more coherent with your routines. Additionally, if you leave the machine unused
for 3+ days, we suggest you rinse the system before starting brewing again and
turn off the machine so that all the components last longer, creating less waste.

15
Extended guide
Screen saver. Once sleepy mode and stand-by are deactivated, but you still
want to prevent the wear of the LED display, the screen saver is automatically
activated.
On the LCC, a square starts moving around. Everything works correctly accord-
ing to set parameters and temperatures, but on the display the coffee boiler
temperature is replaced by the square moving around.
Sleepy mode. The sleepy mode is a machine state where the steam boiler is
turned off and the coffee boiler goes down to 70°C. You can choose when sleepy
mode is activated by setting the time on the LCC (from 30 to 540 minutes).
Stand-by. After 30 minutes of inactivity, the machine automatically goes into
stand-by mode. The LCC display and the heating elements are disabled, and the
ON/OFF button starts ashing.
Note. LELIT Technical team and lab suggest you turn ON and OFF the
machine according to your needs to optimise the energy consumption of your
machine.
12. Functioning modes
The LCC is the brain of the LELIT machines. In LELIT Bianca – PL162T, you
can nd all the functions that can be managed through setting the parameters
in the LCC.
How to adjust the LCC settings:
1. Press the button to enter the menu and scroll through the menu
2. Press the button to change the setting, it will start ashing
3. Change its value and/or state by using the and buttons
4. 3 seconds after the last press of any button, LCC stores the data and
exits from the menu
Note. If you wish to reset the LCC, with the machine OFF, keep the right
key/button pressed, turn the machine ON and wait until the display shows
PRS then turn the machine OFF again.

Partial/Total doses: You can check the number of the total doses that you
brewed with LELIT Bianca. The software counts as one dose any extraction
longer than 10 seconds.
Please keep in mind that this number can’t be reset, and it plays a fundamental
role in maintenance as it suggests and justies the wear of some parts.
What LELIT Technical Department and Lab suggest is to use the partial number
of doses as a reminder of when to change some parts, such as the grouphead
gasket, the anti-vacuum valve and the safety valve.
Pre-infusion
LELIT Bianca can perform pre-infusion. It is the initial phase of the extraction,
and it moistens the coffee puck for a few seconds before the start of the actual
brewing phase. This compacts the coffee powder and makes the ow of the
coffee uniform.
Pre-infusion time ON: This value refers to the starting second of this functioning
mode.
Pre-infusion time OFF: This value refers to the length of this functioning mode.
Once the pre-infusion times (both “time ON” and “time OFF”) have been pro-
grammed, you can start brewing: once the lever is lifted, the pump will be acti-
vated for the previously programmed “time ON” in order to wet the coffee puck.
Afterwards, the pump will stop working for the previously programmed “time
OFF”. Once the “time OFF” elapsed, the pump starts working normally again.

Low flow
The design of the paddle is a LELIT invention implemented in the semi-profes-
sional machines for domestic use.
It is a handle placed on the brewing group that can rotate 200°. While rotating,
it gradually increases or decreases the water ow inside the brewing group,
enabling the highest, manual personalization of every single phase of the coffee
extraction. The water ow, hence, the pressure, can be changed in every mo-
ment of the coffee delivery, until the lever is lowered.
This gives the possibility to get the best out of every coffee blend, managing the
main palate sensations of body, acidity, bitterness, and astringency according
to the different tastes and to your personality. The LELIT user is thus able to
make the most of the characteristics of each coffee type, even the most prized
mono-origin blends, that will express themselves at the best in their fullness.
In the LCC, you can nd two parameters that manage the water ow, hence the
pressure, during coffee brewing:
Low ow start: This value refers to the time slot from the beginning of the brew-
ing process up until the set value.
Low ow nal: This value refers to the time slot from the set value up until the
end of the brewing process.
Low ow and Pre-infusion can be combined to follow the most complex brew-
ing prole. Below, you can see how the water ow changes according to the set
parameters and the extraction time.
Attention. The graphs below show examples of extraction with NO paddle
action.
Note. These graphs are for educational purposes only.

LELIT Bianca - PL162T
There are 4 main situations:
1. Full ow extraction:
Water Flow
Extraction Time
The graph shows a standard extraction with neither low ow nor pre-infusion
activated. There is no action of the paddle.
2. Full ow extraction with pre-infusion:
Water Flow
Extraction Time
This graph shows an extraction where at the beginning there is a blooming/
pre-infusion phase. In these seconds (pre-infusion OFF) there is no water ow
passing through the lterholder and the coffee puck.

19
Extended guide
3. Low ow extraction:
Water Flow
Extraction Time
The graph shows an extraction where the ow is reduced both at the beginning
(low ow START) and at the end (low ow FINAL) of the coffee extraction.
4. Low ow extraction with pre-infusion:
Water Flow
Extraction Time
This graph shows the most complex situation that you can perform by setting the
parameters on the LCC. In the initial phase, both low ow and pre-infusion are
active; at the end, low ow is reactivated to complete the extraction.
Brew temperature off set
This value either increases or decreases the coffee boiler temperature during cof-
fee brewing, changing the temperature of the water coming out of the grouphead.
LELIT Technical Department and Lab suggest to try different values in positive
and negative (rst try +5°C and then -5°C).
If you set a positive parameter, the result is a cup of coffee with more acidity.
If you set a negative parameter, the result is a cup of coffee with more bitterness.

LELIT Bianca - PL162T
13. Technical menu
The technical menu offers extra customization settings for the more expert us-
ers. Please remember that these settings require time before seeing results in
the cup of coffee, however if you think that you changed your machine values
too much, all the settings can be restored with the following procedure:
5. With the machine turned OFF, hold pressed the button
6. Switch the machine ON
7. Wait until the LCC shows KPc value
Note. Keep pressed and until KPc value is shown on the display to be
sure that you have entered the technical menu and not resetting your machine.
Note. If you do not press the button, you have a factory reset of the LCC and
you will have to re-enter and/or check all parameters.
PID
PID stands for Proportional-Integral-Derivative.
Temperature is extremely important when brewing coffee. While different brew
methods and roasts demand different temperature, stability is the key.
All in all, a machine with PID control monitors itself to ensure temperature
stability and control.
A traditional thermostat tends to hit a desired temperature, then turn off the heat-
ing element as the temperature rises above its target. Then it will kick back on as
the temperature falls below the set value. These results in uneven temperatures
can lead to inconsistent shot quality in a coffee machine, like LELIT Bianca.
PID controllers use the PID algorithm to keep your machine at the proper brew
temperature. This also means that you can directly control the temperature of
the machine. The temperature detected inside the boilers is the one visible on
the display and it is subjected to all the variations happening inside the boilers.
Note. PID is an algorithm that regulates the boiler temperature according to
the temperature detected by the probe (NTC) located inside the boiler. PL162T
having two boilers has therefore two working PID: the letter c at the end of the
parameter (e.g., KPc) refers to coffee boiler; the letter s at the end of the param-
eter (e.g., KPs) refers to steam boiler.
