Proper water ltraon and regular lter changes are a requirement to keep your factory warranty valid
and your machine funconing properly. It is highly recommended that you contact a professional water
ltraon specialist in your area and have your water tested to determine the proper ltraon system. It is
important to note that many municipalies change their water sources throughout the year, so addional
water tests may become necessary.
Water Standards to keep your warranty valid:
In Synesso’s experience, Everpure Claris and Cirqua formulator systems can damage the
Synesso stainless steel tanks. Use of either system is highly discouraged and will void the
water related parts of the machine warranty.
Any part which is determined to be defecve in materials or workmanship should be returned to Synesso or
to an authorized service locaon, shipping costs prepaid, as Synesso designates. Synesso may repair or re-
place the product or part with new or factory refurbished equipment at Synesso’s sole discreon. If the
product or part is determined to be defecve and in compliance with the Limited Warranty condions, the
replacement part or product will be returned to the purchaser with shipping prepaid **.
Many jurisdicons have codes and regulaons governing sales, construcon, installaon, and/or use of
products for certain purposes, which may vary from area to area. While Synesso aempts to assure that its
products comply with such codes, it cannot guarantee compliance and cannot be responsible for how the
product is used or installed.
Synesso’s liability is limited to the purchase price of the product and shall not be held liable for damages
that extend beyond the product itself. Synesso’s liability of consequenal, incidental damages, indirect or
direct damages for personal injury, inability to properly use this product, loss of business prots or interrup-
on to business is expressly disclaimed.

PLUMBING REQUIREMENTS
This equipment must be installed to comply with the applicable federal, state or local plumbing codes.
WATER TREATMENT IS REQUIRED TO PRESERVE THE FULL MACHINE WARRANTY. Please ensure that the
incoming water complies with the warranty requirements listed on page 8.
Using the provided stainless steel braided hose, connect the pump to the shuto valve on the ltered cold
water line. Fings on the hoses and pumps are 3/8” tube compression. Thread sealant or Teon tape is not
necessary. Make connecons snug, but do not over ghten.
Turn incoming water ON and check for leaks.
Synesso machines require a minimum of 50 PSI (3.5 bar) of line pressure at 30 gal (120 L) per hour to have
the auto-ll system, for the steam tank funconing properly. Please ensure that the incoming water meets
this requirement or contact Synesso for alternave methods of boosng water pressure.
NOTE: Synesso sells a “Euro-hose” adaptor hose and ng which converts from a 3/8” tube ng to a pipe
ng, suitable for most non-US plumbing. Please refer to the picture below to idenfy the dierences
between the standard and Euro-style ngs and hoses.

ELECTRICAL REQUIREMENTS
All Synesso machines are rated to operate on 220 VAC / 60 Hz or 230 VAC / 50 Hz frequency, single phase.
Machines will operate between 208 V and 240 V.
Listed amp rangs are all measured at 220 V. Incorrect voltage can cause malfuncon or damage to the ma-
chine. Plug or means of isolaon must be easily accessible.
An electrical socket and matching plug, rated at the proper voltage and amperage are required within three
feet of the machine. Plug ends are NOT included with the machine unless required by CSA or other cerca-
on.
Aach the plug end per manufacturer’s instrucons.
Make sure that the electronics switch and the heang element breaker are in the OFF posion, then plug the
power cord into the receptacle.
OPTIONAL: If recovery me is slow, or voltage is low, you may install an In-Line Buck-Boost transformer.
Buck-boost transformers come in dierent sizes. Please choose the appropriate one for your machine if re-
quired. Machines require a 1.0 KVA transformer.
SPECIAL ELECTRICAL INFORMATION FOR EMC-COMPLIANT MACHINES
(CE FOR EUROPE AND OTHER LOCATIONS)
To comply with EMC (Electromagnec Compability) regulaons, machines built prior to May 2019 included
a capacitor in the electronics box across the main power IN. To avoid an electric shock from the charge held

INSTALLATION & WORK STATION
To maintain the 2 year warranty, an authorized or cered espresso service representave
must perform the installaon of this espresso machine.
Site Preparaon - See Diagrams pages 12-13. The machine must be placed on a level horizontal surface that
can be easily cleaned and is capable of supporng a minimum of 300 lbs.
The counter top requires a depth of 28”, which provides a minimum clearance of 1” behind and 3” in front
of the machine.
The height of the surface can vary to suit the operator.
Make a 2 ½” minimum diameter hole through the counter top located according to the diagrams on pages
12 and 13. The hoses, drain tube, and electrical lines will all pass through this hole.
A 3/8” min. diameter cold water supply line from the lter with a shut o valve is required within 5’ of the
machine. The valve should be easily accessed for machine service.
The machine supply hose and pump ngs are 3/8” tube compression ngs.
A proper water ltraon or soening system must be installed on the incoming water supply. Water treat-
ment requirements will vary, and it is important to use a system designed to match the needs of your spe-
cic area. Water ltraon systems require periodic maintenance, including cartridge or lter replacement.
Proper ltraon and service is vital to the funcon of the machine and the quality of the espresso served.
Follow the instrucons provided by your water treatment system for proper installaon.
Note: Improper water ltraon can result in severe damage to the machine including scale deposits and cor-
rosion. DAMAGE CAUSED BY IMPROPER WATER TREATMENT WILL NOT BE COVERED BY THE MACHINE
WARRANTY. See page 8.
There must be adequate room under the counter to locate the motor and pump. The pump must be easily
accessible for adjustment, and the motor must have a minimum of 3” clearance on all sides for air ow.
A oor drain or sink must be available. The best locaon is directly under the machine. The 3/4” drain hose
should descend as vercally as possible for opmal drainage. An air gap is required between the end of the
drain hose and the highest water posion of a clogged drain. This is to prevent the possibility of drain water
backing up into the machine.

START UP
First Time Start-Up Instrucons
1. Connect the water lines and the drain hose. Turn the water ON. Water will begin to ow into the brew
groups.
2. Ensure the heang element breaker switch is in the OFF posion. Then switch the red electronics On/O
switch to the ON posion. The machine’s auto-ll feature will acvate and the steam tank will begin lling.
3. Bleed the air from the group heads by running each group unl water ows without spuering.
4. When the steam tank has stopped lling, set the heang element breaker to the ON posion. The machine
will begin heang to the set temperatures.
10Heang Element
Switch
ON: le posion (1)
OFF: right posion (0)
5. To set the pump pressure to 9 bar, locate the pump adjusng screw on the right side of the brass pump
housing. Loosen the lock nut and turn the screw with a screwdriver (Clockwise to INCREASE pressure,
Counterclockwise to DECREASE pressure). Make adjustments while running the shot programs to see the
current pump pressure. Once the desired pressure is reached, reghten the lock nut.
6. Please allow at least 30 minutes of “warm up” me before using your Synesso™ espresso machine to
brew shots or steam milk. The steam gauge (the le hand gauge) should read a minimum of 1.1 bar be-
fore the steam tank is at an operaonal pressure and will stop at 1.3 bar when the factory set tempera-
ture of 250°F is reached. The factory set temperatures for each brew tank is 203°F. Temperature readings
for the steam and brew tanks are displayed on the handheld controller. Temperature set points can be
adjusted by following the instrucons on pages 19 and 20. Once the readings are at the set temperature,
the machine is fully operaonal and ready for use.
Note: As the brew groups heat, the needle of the brew pressure gauge may rise above 11 bar. There is an ex-
pansion valve used to control the maximum pressure achieved. This valve is posioned to bleed into the
drain tray of the machine and is accessible for adjustment from the front of the machine without having to
remove machine panels. The expansion valve is factory set to bleed o pressure at 11-12 bar. If the needle
rises above 12 bar on the pressure gauge, the expansion valve should be adjusted to bleed o pressure near
11-12 bar so that the maximum pressure reading of the brew gauge cannot exceed 12 bar. The expansion
valve requires periodic adjustment throughout the lifeme of the machine to ensure that the pressure in the
brew system is not able to increase above 12 bar.
7. Once the steam pressure gauge reads at or above 1.1 bar, you may purge the steam wands. To purge the
steam wands, rst posion the wand p into the drain tray. Acvate the steam wand by pulling the steam
wand handle toward you. Aer allowing steam to escape for several seconds, turn the steam o by returning
the handle to the resng posion.

OPERATION
Introducon to S Series Operaon
S Series machines are designed to operate as fully volumetric machines. This means that any me a group is
acvated, it will run the selected program unl the set volume has been dispensed. S Series machines do
not have a manual operaon mode.
S Series machines come with a single pump/motor. They are designed to operate with two stages of pres-
sure proling for brewing espresso. The shot begins with preinfusion. Low pressure water saturates the
puck, swelling it to reduce channeling. Aer the programmed preinfuse me has elapsed, the full pump
pressure (typically 9 bar) stage begins. This stage will connue unl the programmed volume of water has
been dispensed. The pump and brew group then shut o to end extracon, returning the machine to idle
pressure.
S Series machines come equipped with a handheld controller and LCD display to allow for adjustments of
the machine tank temperatures and brew parameters. Each brew group has two available programs which
can be easily accessed and adjusted through the controller.
Preparing to Brew Espresso
1. Select the desired spout and basket conguraon. Single, double and boomless portalters are availa-
ble through Synesso™. The single spout portalter is used with a single (7g) basket to brew a single shot.
The double spouted and boomless portalters can be used with double (14g) or triple (18g or 21g) bas-
kets to brew double or triple shots. The double spouted portalter can separate a double shot into 2 sin-
gle shots of espresso.
2. Fill the portalter basket with coee grounds to just above level and wipe o the excess.
Note: For best results, use fresh coee. Ground coee should be brewed as soon as possible aer grinding.
3. Press straight down evenly on top of the grounds with the tamper. (A tamper is supplied with the ma-
chine).
4. If desired, purge the group to heat the diuser before proceeding to the brewing process. S Series ma-
chines have purge buons, which will dispense a med pulse of full pressure water to aid in cleaning or
warming the group between shots. Set the duraon of the purge in the handheld controller.

Brewing Espresso
1. Engage the prepared portalter into the brew group that has the correct temperature seng for this es-
presso roast and pull handle rmly to the right to set the seal.
2. Shi the group head either to the le to run the le program or to the right to run the right program.
3. The program will preinfuse the puck for the set me, then engage the pump.
4. Once the set amount of water has been dispensed, the shot will end automacally.
5. You may change the preinfusion me and shot volume by using the handheld controller (see page 20 for
programming instrucons). Make changes between shots, not while brewing.
6. To stop a shot early, shi the handle in either direcon or press the purge buon.
7. Aer the shot, remove the portalter, tap out your spent puck, and clean the basket.
8. Purge the group. S Series machines have purge buons, which will dispense a med pulse of full pressure
water to aid in cleaning the group between shots. Set the duraon of the purge in the handheld control-
ler.

Milk Steaming
1. Fill the pitcher halfway with fresh, cold milk. Smaller pitchers are recommended for drink sizes less than
10 oz. Note: Steamed, unused milk should be discarded and the pitcher rinsed before using.
2. Purge the steam wand by acvang it momentarily. This will expel any water in the wand that has collect-
ed due to condensaon between uses.
3. Insert the p of the steam wand deep into the milk pitcher. This will prevent milk from splashing once the
steam is turned on.
4. Open the steam valve by pulling the handle towards you.
5. Place one hand on the side of the steam pitcher to feel the rising temperature of the milk.
6. While the milk is sll cold, lower the pitcher unl the p of the steam wand is near to the surface. Allow
the steam jets to push some air beneath the surface, then raise the pitcher to lower the p of the wand
deeper into the milk. Note: The more air pushed into the milk, the more foamy the texture will be. Gen-
erally not more than a second of aeraon is needed for lae foam or several seconds for cappuccino
foam.
7. Connue steaming the milk while the wand is submerged. This will connue the heang process and min-
imize further foaming. Do not touch the steam wand to the boom of the milk pitcher; this can create an
inaccurate temperature measurement.
8. Heat the milk to approximately 150°F to 170°F (65°C to 76°C) then deacvate the steam wand. If you are
using your hand to help determine the temperature, it will feel about as hot as you can stand without
burning yourself. Milk thermometers are also an excellent way to determine the temperature of the milk.
Cauon: Do not overheat the milk and scald it. Scalded milk should not be used.
9. Remove the wand from the milk, purge with steam, and wipe clean immediately aer each use.
Note: The steam wands should be purged before and aer each use. Failure to purge the wands may
allow the steamed liquid to travel back through the wand and cause steam valve failure and spoiled, scalded
milk avor. These issues are fully preventable by habitually purging the wands, as described above, and keep-
ing the machine up-to-date on preventave maintenance.
Note: Although Synesso™ steam wands are made with a proprietary double-walled process that helps to
keep the outer wall cooler, the p and base can become very hot and cauon must be used.
Cleaning and Maintenance:
Machine upkeep is essenal in order to ensure a long lifeme of the machine and the proper funconing of
all components. Users should perform roune cleaning and schedule roune preventave maintenance to
keep the machine at opmal performance.

PROGRAMMING
Overview
S Series machines have a handheld (wired) controller, pictured below, to allow the user to comfortably view
and change the machine sengs.
To change sengs on these screens, rst press the line buon on the le side of the display associated
with the seng you wish to change. The value will ash once selected. Press the up or down buons unl
the desired value is displayed. Press the line buon again to conrm the change. The value will stop ash-
ing. Use this procedure to change any variables in the controller menus.
The top line of every screen indicates the tle. In this case, Temperature Overview.
You can return to this screen at any me by pressing the home buon at the top right of the controller.
The machine will also return to this screen automacally aer a short me.
Lines 2, 3, and 4 may contain informaon or sengs, many of which can be changed by the operator. This
screen provides the current temperatures for each brew group along with the steam tank. The most recent
error will also be shown in the lower right corner. No sengs can be changed on this screen.
In some circumstances, numeric temperatures will not be shown. If a tank is reading ‘LOW’, this indicates
that the tank is below the temperature probe’s eecve range of measurement (170°F-270°F / 76.6°C-132.2°
C). Readings above the eecve range will show as ‘HIGH’.
The programmable temperature range for a brew group is from 180°F (82.2°C) up to 220°F (104.4°C). The
factory set temperature is 203°F (95°C). To change brew group set temperatures, refer to page 19.
The steam tank is set in factory to a default seng of 250°F (121.1°C). To change this temperature seng,
see page 20.
The [OK] on the right hand side of line 4 is indicang that there have been no errors detected by the control
system. If, in place of the [OK] you nd an error code (Ex: STLW01), refer to the Error Log codes on page 22.
To cycle to the next display screen, press the down arrow buon. (You may press the up arrow instead to
travel back to the previous screen.)

PROGRAMMING
Factory Sengs:
The factory sengs for your machine are as follows:
Brew Group Temperature 203°F
Steam Tank Temperature 250°F
Program Mode Universal (2 programs)
Temperature Units Fahrenheit
Le program: Right program:
Pre-Infusion 4 seconds Pre-Infusion 4 seconds
Total Water Count 280 Total Water Count 380
The set point is a goal temperature for the brew tank. The tank will heat to reach the set point, then use a PID
based algorithm to remain stable and balanced at that temperature when in use.
Allow 10-15 minutes for a brew group to adjust to a large set point change. Smaller changes take less me to
restabilize.
Line 2 indicates the set point for brew group 1, in this example “203.0F”.
Line 3 indicates the set point for brew group 2, in this example “203.0F”.

PROGRAMMING
If the machine has been set to universal program mode, you will be able to change the “Le” and “Right”
program, seng the preinfusion me and water count for each. Each brew group will use these programs.
This is the default mode.
If the machine has been set to individual program mode, there will be a separate page for the le and right
programs on each brew group. This allows the groups to use dierent programs. This mode can be selected
in the 2nd level menu. (See page 23)
Line 2 indicates program 1, acvated by a le shi of the group top handle and program 2, acvated by a
right shi of the group top handle.
Line 3 indicates the adjustable preinfusion values in seconds for the le and right programs. If the value is
adjusted to 0 seconds, the preinfusion stage will be skipped.
Line 4 indicates the adjustable ow count values. There are about 4.5 counts per milliliter of water dispensed.
Some of this dispensed water is absorbed and retained by the coee puck, but generally, if you add 9 counts,
you should receive 2 addional mL of water.
