WARRANTY
Limited One-Year Non Wearing Parts Warranty

Synesso™, Inc and/or your Distributor warrants to the original purchaser that Synesso™espresso machines are free from
defects in materials and workmanship under normal use and service for the period commencing upon the date of shipping
and continuing for 12 months from the original date of shipment. Synesso™will make a good faith effort for prompt
correction or other adjustment with respect to any non-wearing part that proves to be defective within the limited warranty
period. This Limited Warranty is conditional upon proper use of the machine by the purchaser.

This Limited Warranty does not cover defects or damage resulting from: accident, misuse, abuse, shipping damage,
neglect, unusual physical, electrical or electromechanical stress, unauthorized customer modifications or improper water
filtration.

Proper water filtration and regular filter changes are a requirement to keep your factory warranty valid and your machine
functioning properly. It is highly recommended that you contact a professional water filtration specialist in your area and
have your water tested to determine the proper filtration system. It is important to note that many municipalities change
their water sources throughout the year, so additional water tests may become necessary.

Water Standards to keep your warranty valid:

Total Dissolved Solids (TDS) 30 to 200 ppm (parts per million)
Total Hardness - in ppm Less than 85 ppm
Total Hardness – in grains 3 to 5 grains (divide ppm by 17.1 to get grains)
pH 6.5 to 7.9 pH
Chloride 0 ppm – Chloride can damage the boilers
Total Alkalinity Less than 100 ppm
Chlorine 0 ppm
Iron 0 ppm

In Synesso’s™ experience, Everpure Claris and Cirqua formulator systems can
produce a result that can damage the Synesso™ boilers. Use of either of these
systems is discouraged, and will void the water-related parts of the machine
warranty.

Any part which is determined to be defective in materials or workmanship should be returned to Synesso™ or to an
authorized service location, shipping costs prepaid, as Synesso™ designates. Synesso™ may repair or replace the
product or part with new or factory refurbished equipment at Synesso’s™ sole discretion. If the product or part is
determined to be defective and in compliance with the Limited Warranty conditions, the replacement part or product will be
returned to the purchaser with shipping prepaid **.

Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for
certain purposes, which may vary from area to area. While Synesso™ attempts 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 Synesso™ shall not be held liable for damages that
extend beyond the product itself. Synesso’s™ liability of consequential, incidental damages, indirect or direct damages
for personal injury, inability to properly use this product, loss of business profits or interruption to business is expressly
disclaimed.


Site Preparation - See Diagram p.9


The machine must be placed on a level horizontal surface that can be easily cleaned and is capable
of sustaining 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.


Make a 2 ½” minimum diameter hole through the counter top located 4” from the rear and 7” from the
right side of the machine. The hoses, drain tube, and electrical lines will all pass through this hole.


A 3/8” min. diameter cold water supply line from the filter with a shut off valve is required within 5’ of
the machine. The valve should be easily accessed for machine service.


The machine supply hose and pump fittings are 3/8” tube compression fittings.


A proper water filtration or softening system must be installed on the incoming water supply. Water
treatment requirements will vary, and it is important to use a system designed to match the needs
of your specific area. Water filtration systems require periodic maintenance, including cartridge or
filter replacement. Proper filtration and service is vital to the function of the machine and the quality
of the espresso served. Follow the instructions provided by your water treatment system for proper
installation.
Note: Improper water filtration can result in severe damage to the machine including scale deposits
and corrosion. DAMAGE CAUSED BY IMPROPER WATER TREATMENT WILL NOT BE COVERED
BY THE MACHINE WARRANTY. See page 7.

There must be adequate room under the counter to locate each motor and pump. The pumps must be
easily accessible for adjustment and motors must have a minimum of 3” clearance on all sides for air
flow.

A floor drain or sink must be available. The best location is directly under the machine. The 3/4” drain
hose should descend as vertically as possible for optimal drainage. An air gap is required between
the end of the drain hose and the highest water position of a clogged drain. This is to prevent the
possibility of drain water backing up into the machine.

ELECTRICAL REQUIREMENTS


All Synesso™ machines are rated to operate on 220v AC with a 50 or 60 Hz frequency, single phase.
Machines will operate between 208v and 240v.


Listed amp ratings are all measured at 220v. Incorrect voltage can cause malfunction or damage to
the machine.

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 certification.



Make sure that the red electronics switch and the heating element breaker on the front of the
electrical box are in the OFF position, then plug the power cord into the receptacle.

OPTIONAL: If recovery time is slow, install an In-Line Buck-Boost transformer to increase voltage
below 208v to optimize machine recovery time. Buck-boost transformers come in different sizes.
Please choose the appropriate one for your machine if required. 1 and 2 Group Machines require a
1.0 KVA transformer, 3 Group Machines require a 1.5 KVA transformer.


SPECIAL ELECTRICAL INFORMATION FOR EMC-COMPLIANT MACHINES
(C-TICK FOR AUSTRALIA, CE FOR EUROPE AND OTHER LOCATIONS)
To comply with EMC (Electromagnetic Compatibility) regulations, Synesso™is required to install a
capacitor in the electronics box across the main power IN. To avoid an electric shock from the
charge held in the capacitor, unplug the cord, taking care to NOT touch the metal prongs on
the plug end. Turn the electronics ON/OFF red rocker switch to the ON position and wait a few
seconds until the red switch “goes dark.” At that point, the electrical charge has dissipated.

HYDR
A
/
HYBRID

The Hydra is a machine model with a pump and motor for each group head. This includes changes
in internal plumbing and wiring to accommodate separate and distinct pressures in each brew group.
In contrast, a Cyncra or Sabre has a single pump and motor for the entire machine. Having individual


pumps and motors allows the operator to set a separate brewing pressure per group head, and each
group functions independently without affecting the pressure at the other groups.


Hydras can be built as fully manual machines (multiple manual group heads), fully volumetric (all
group heads have programmable keypads), or a mixture of group heads to match your requirements.
Hydras with mixed group head configurations are referred to as Hybrids.
Hydra Installation requirements:
Electrical:
The Hydra package has a slightly greater amp draw than the single pump machines; please note the
max amp draws and plan your electrical installation accordingly. See table on page 11.


Each pump motor has a distinct color association, which is indicated throughout the machine by
colored wires and zip ties. The colors are as follows:
Group 1: Grey
Group 2: Purple
Group 3: Brown
Water inlet for the steam tank: Pink


Wherever these colors are seen, it is critical for proper functioning that they are matched up correctly
(grey to grey, etc.) for both electrical and plumbing systems.


Plumbing:
Hydra packages require one incoming water source like single pump machines. The water passes
through a manifold (commonly part of the line pressure regulator) and is distributed to each pump.
Once again, follow the color coding for proper installation of the hoses from the output of each pump
to the machine.

Pump cord installation: Insert the color coded pump cable into the opening of the matching bypass
box and attach the wires to the terminal as shown in the picture above: green wires stacked on the
ground bolt, white to white/red, black to black/blue, connect the bullet connectors.

Pressure regulator: Used to achieve the stage 1 low pressure pre-infusion. It is set and tested at 50
psi in the Synesso™ factory. This pressure setting can be lowered if desired, but 50psi is the maxi-
mum output pressure. To adjust the pressure regulator, first loosen the nut on the threaded post, then
turn the post counter-clockwise to decrease pressure.
Pump Bypass: First, set the pump and regulator to the desired pressures.
Manual group: Turn the associated brew group actuator to brew (2nd)
position, then back to the first position.
Volumetric group: set stage 1 time and bypass percent to zero. Press the
pitcher button.
The pin valve on the pump may then be adjusted until the brew gauge indi-
cates the desired pressure. 7 bar is our factory setting. Adjust to taste.

The Stage 1 (Pre-infusion) time and Stage 2 (By-
pass) time are set on the Temperature Control
screen of the display by following the directions
on page 33. Stage 1 time is set to 7 seconds and
Stage 2 is set to 3 seconds at the factory. Adjust to
taste.


Once these settings are in place, you will be able to taste the effects of four stage pressure ramping
applied to each shot. Start the shot to begin the Stage 1 pre-infuse timer. In this stage, low pressure
water will saturate the puck, swelling it to reduce channeling. After the stage 1 time has elapsed,
stage 2 bypass will begin. In this stage, the bypass system will help create a slow rise in water pres-
sure by diverting high pressure water away from the brew group. After the stage 2 time has ended,
the bypass will close and stage 3, full pump pressure (9 bar) will begin. Stage 4 is a return to by-
pass pressure. In the case of manual groups, entering stage 4 is determined by the operator and is
achieved by moving the group top actuator back to position 1. Volumetric groups can be programmed
to automatically begin stage 4 at a set percentage of the shot as described on page 57.

Start-Up Instructions
1.
T
o fill the machine, connect the water lines, set the drain hose and turn the water ON.


2. Switch the red electronics On/Off switch to ON. This activates the machine’s water auto-fill
feature for the steam tank and the electronics, but NOT the heating elements.
3. The water level sight glass for the steam tank is located on the right side of the machine. As
the tank fills, the water level will rise in the sight glass and will automatically stop when the
preset level is reached.
4. Bleed the group heads of air:
Manual machines: Turn each group head handle left into the BREW position, (see pictures
below) allow the group to run until there is a steady flow of water. Return the group head to the
OFF position.
Volumetric machines: Activate the pitcher button on the right side of the keypad. Once the
water flows in a steady stream, press the pitcher button again to stop the water.
5. Wait until the steam tank has stopped filling and the level in the sight glass reads at
least ½ full. Turn the heating element breaker to the ON or (1) position. All the heating
elements (brew and steam) are now activated.
6. To adjust the pump pressure, activate the pump by turning the brew group to the BREW
position. On volumetric machines, activate the pump with the pitcher button.
7. Locate and read the pump pressure / brew gauge located to the right of the rightmost group on
Cyncras and Sabres or to the right of each group on Hydras.
8. Set the pump pressure to 9 Bar:
Locate the pump adjusting 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
Once the desired pressure is reached, retighten the lock nut.
9. Please allow at least 30 minutes of “warm up” time before using your Synesso™espresso
machine to brew shots or steam milk. The steam gauge (the left hand gauge) should read a
minimum of 1.1 Bar.

Prepare a Portafilter


1. For best results, use fresh coffee. Ground coffee should be brewed as soon as possible after
grinding.
2. Select the correct spout and basket configuration. Single, double and bottomless portafilters
are available through Synesso™. The single spout portafilter is used with a single (7g) basket
to brew a single shot. The double spouted or bottomless portafilters can be used with double
(14g) or triple (18g or 21g) baskets to brew triple, double, or 2 single shots of espresso.
3. Fill the portafilter basket just above level and wipe off the excess.
4. Press straight down evenly on top of the grounds with the tamper.


NOTE: When not in use, keep the portafilter engaged in the group head to keep it warm.

Espresso Brewing


1. Grind a dose of coffee appropriate to the basket you will be using.
2. Dispense into the portafilter basket.
3. Level the mound and compress using a tamper. (A tamper is supplied with the machine.)
4. Engage the portafilter into the brew group that has the correct temperature setting for this
espresso roast and pull firmly to the right to set the seal.
(Manual)
5. Pre-infuse the coffee puck by turning the brew group clockwise to the center position. This
allows line pressure to saturate the puck.
NOTE: If a stage 1 or 2 time is set on the display, they will begin automatically whenthe actuator is
switched to the brew position, so the pre-infusion position should be skipped.
6. When a drip shows at the spout (or on the basket if bottomless), Turn the group cap clockwise
again to the brew position. This engages the pump.
7. When the stream of coffee turns from brown to “blonde”, end the shot by returning the group
cap to the far right position. Machines using pump bypass hardware may move back to the
preinfuse (center) position just before the shot blonds to extend the extraction and delay
blonding.
(Volumetric)
5. Press one of the first 4 buttons on the button pad.
6. If stage 1 or 2 timers have been set, the machine will execute these times automatically, then
move into the brew stage. Machines equipped with pump bypass systems can use an
automatic bypass at the end of the shot. See page 34.
7. The shot will automatically end once the set volume of water has been dispensed.

Milk Steaming


1. Fill the pitcher halfway with fresh, cold milk. Smaller pitchers are recommended for drink sizes
less than 10oz. Steamed, unused milk should be discarded.
2. Condensation can collect inside the wand. Activate the steam handle to blow the wand clear
before steaming milk.
3. Insert the tip 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. As the milk agitates and heats, lower the pitcher to keep the tip of the steam wand closer to
the surface. Allow the steam jets to push some air beneath the surface, then raise the pitcher
to lower the tip of the wand deeper into the milk. This will continue the heating process and
minimize further foaming. Do not touch the steam wand to the bottom of the milk pitcher; this
can create an inaccurate temperature measurement.
7. Heat milk to approximately 150F to 170F (65°C to 76°C). 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.
Caution: Do not overheat the milk and scald it. Scalded milk should not be used.
8. Remove the wand from the milk, purge, and wipe clean immediately after each use.


NOTE: Although Synesso™ steam wands are made with a proprietary double-walled process that
helps to keep the outer wall cooler, the tip and base can become very hot and caution must be used.

NOTE: Whole Milk, 2%, 1%, Non-Fat, Soy Milk, Rice Milk and other milk type products may require
different techniques to foam properly. In general, the higher the fat content, the easier it is to steam.

HYDRAULIC SYSTEM
Overview

The hydraulic system in the Synesso™ is comprised of all parts through which water flows starting


with where it enters the machine from the water treatment/filtration system. This chapter will detail the
flow of water and some of the associated electrical components.


Synesso™ utilizes 3/8” braided stainless hoses (supplied with machine) to connect to the water treat-
ment system. Once the machine is set up and the water quality is checked, the machine is ready to
connect to the water treatment system. The water then passes to the pump and motor.

On single inlet machines, the water then travels through one hose to the machine and supplies both
the coffee boiler system and the steam boiler.

On dual inlet machines, the water diverts at the pump: the water for the coffee boiler goes through the
pump and the water for the steam boiler travels through a separate line. The next 3 pages show the
dual, single, and Hydra inlet water paths.
