Introduction
Precisia SYL-100
Thank you for purchasing the Precisia SYL-100 espresso and cappuccino machine. We
sincerely appreciate your decision and trust that our machine will meet your expectations
in both the quality of the espresso produced and the high value of our product. While we
are delighted that you may be anxious to brew some espresso or make a delicious
cappuccino, a few minutes of your time reading through this manual now will only serve
to enhance your espresso experience in the months and years ahead. In particular, we
would urge you to read through the safety warnings below. Although brewing and
drinking espresso is a delightful experience, the process involves hot water under high
pressure and your safety is paramount.
SAFTY WARNINGS
•The power source must meet the specifications of the coffee machine with correct
voltage and proper grounding connections.
•Do not attempt to remove the portafilter holder during or immediately following the
brewing operation. Very hot water under high pressure will spray out possibly
causing injury to the user. Wait 15 seconds after brewing stops before removing
the portafilter assembly.
•Do not touch the metal tubing of the steam wand nozzle during and right after
frothing milk. Do not touch the bottom or sides of the group head when the
machine is on. These surfaces are very hot.
•If an abnormal display or noise is observed, turn the machine off, unplug the
power cord and contact the manufacturer before using it again.
•Do not move the machine when water is present in the reservoir. Water may spill
inside the machine causing permanent damage or electric shock.
•Clean the machine only when it is cool and unplugged.
•Empty the water reservoir if the machine will be subjected to freezing
temperature.
•Do not allow children to operate machine unless they are under adult supervision.

Our Mission
Precisia Coffee is dedicated to manufacturing precision temperature controlled home
espresso machines. It is widely recognized that proper brewing water temperature is
one of the most important factors affecting the taste of the espresso. If the water
temperature is too low, it will not completely extract the aroma from the coffee.
However, if the water temperature is too high, it will extract unwanted bitterness.
Experts believe that the brewing temperature for any particular blend of espresso beans
(optimum is typically between 196 F and 204 F) should be maintained within one degree
during the extraction process in order to produce the best tasting espresso. In addition,
each individual may have their own taste preferences of that coffee which can be
affected by the brewing water temperature. Most home espresso machines use a
simple snap action on-off thermostat as a means of controlling water temperature. This
can allow for a fluctuation of up to 40 degrees (Fahrenheit) in the brew water
temperature and is the primary reason why most espressos made in the home cannot
equal the taste of an espresso brewed in a commercial coffee cafe.
Precision Temperature Control
The Precisia SYL-100 incorporates a custom developed temperature control system
utilizing a PID algorithm that can maintain the water temperature for brewing your
espresso within one degree of the selected value. Users can easily change the water
temperature to suit their own taste. The actual temperature of the boiler is displayed by
a bright red LED display with a green light signifying when the water is ready for brewing
your espresso.
Home espresso machines usually require a rapid heat up speed. This requirement
makes it difficult to obtain precision and stable temperature control, especially for a
stainless steel boiler/group head. Precisia has achieved superior performance with
these usually-contradictory parameters through innovative hardware and software
design. The system generally takes about 5 minutes to heat up from room temperature
and less than 2 minutes between each shot.
Precision Shot Volume Control
The shot volume of the espresso can be easily adjusted to suit the user’s preferences.
The shot volume is adjusted by varying the pumping time with one-second accuracy.

Stainless Steel Group Head
Precisia uses a stainless steel grouphead for better taste and uniform temperature rather
than the more commonly used brass group heads which have the tendency to absorb
coffee oils and negatively affect the taste.
With Precisia, you are in total control of your espresso!

Unpacking the Precisia SYL-100
The Precisia SYL-100 comes nicely packaged in a sturdy cardboard box with formed
styrofoam inserts to prevent damage due to shifting during transit.
Carefully inspect the exterior packaging of the machine for any signs of damage during
transit. Pictures of transit damage are invaluable should it be necessary to file a claim
with the delivery service or carrier.
The machine itself is wrapped in an easily removable plastic bag. After removing the
machine from its box and removing the plastic bag, remove the blue-colored protection
film from the warming plate and replace the plate back on the top of the machine.
All of the filter baskets and portafilter are in the styrofoam block tightly packed beneath
the control panel. Slightly rotate the steam nozzle outwards and push the styrofoam to
the left to get it out. The steaming/frothing thermometer is inside the water reservoir.
CAUTION
Do not leave the bag where younger children can easily
access it.
A good idea would be to store the plastic bag and all other packaging materials back in
the Precisia box for later use.
Visually inspect the machine for any damage due to shipping and handling.

CAUTION
After steaming, the steam wand is very hot. Be extremely careful with
your hands and fingers when moving (rotating) the high temperature
steam wand.
Please select a stainless steel steaming pitcher of proper height and capacity.
Recommended steaming pitcher sizes range from 12 to 20 ounces in capacity. Fill the
steaming pitcher approximately 1/4 to 1/3 of its capacity with the fresh chilled milk of your
choice. This will ensure sufficient frothed milk for two delicious cappuccinos or lattes.
After you are finished the frothing operation, clean the nozzle internally by briefly
releasing a small burst of steam into a wet cloth and then wipe the outside of the nozzle
with that same wet cloth.

Initial Setup
Cleaning the Parts. Rinse the water container and fill it with filtered water to just below
the 1.25-liter mark. Before sliding the reservoir back into position, place the two silicone
tubes inside the reservoir.
Plug the power cord into a standard 115-120VAC grounded receptacle and note that the
red power indicator LED is lit. If, by some chance, the green LED starts flashing, press
the On/Off button to turn the machine off.
Place a normal coffee cup on the drip tray directly underneath the grouphead shower
screen and turn the machine on. Now press the ESP button to initially fill the boiler with
water. The pump will operate for 14 seconds (this is the default timer setting set at the
factory) drawing water from the reservoir. Repeat this process two more times for a
total of three pumping cycles. You should notice a small change in the sound of the
pump when the boiler is full and water begins flowing from the grouphead shower
screen.
Mount the portafilter assembly to the grouphead. Slide the portafilter basket locking
mechanism back (in the direction of the arrow) and place any one of the three baskets in
the portafilter. Make sure the basket lock remains slid back. Install the portafilter
assembly into the espresso machine by holding the filter assembly level with the handle
approximately 60 degrees to the left (8:00 o’clock position). Turn the portafilter
assembly counterclockwise for approximately 60 degrees (until the handle is at 6:00
o’clock or until it feels snug).
CAUTION
The portafilter assembly cannot be properly installed in the
machine with the basket lock engaged. Attempting to install
the assembly into the machine in this manner may cause
damage to the portafilter assembly or the grouphead or both.

from room temperature (72-76 F) to the temperature set for espresso brewing (208 F is
the default).
Any time the machine is “on”, the three adjustable parameters of pumping time (SEC),
espresso water temperature (ESP), and cappuccino steaming temperature (CAP) can be
adjusted to suit YOUR preferences. This is done by pressing the “SET” button which
will put the machine into the Parameter Setting mode.
The chart shown below shows the sequence of parameters when the SET key is
pressed:

The LED display will show the current temperature (which will begin to rise) and the
esso brewing water temperature and pumping time (this step can be skipped
if there is no desire to change the default values). However, please do not forget to
change the pumping time if you are switching from pods (single-shot- 14 seconds) to
a double-shot basket (19-21 seconds) or vice-versa.
•When the machine reaches set temperature, activate the pump again for one brew
cycle to heat up the installed portafilter and basket.
NOTE
In order to produce the best espresso that Precisia is capable
of, we recommend that you always first “pull a blank shot” of
hot water through an empty basket and portafilter prior to
making a “real shot.” The idea here is to make sure the
boiler is as full as possible and to heat up all the components

3. The default value of the espresso brewing temperature parameter (ESP) is set at
208 F which is measured on the top surface of the boiler. The temperature of the
water exiting the grouphead is about 8 F lower than the temperature shown on the
display panel.
4. Precisia utilizes brew water pressure to assist in packing the ground espresso to
