Page 7: Installation
INSTALLATION To maintain the 1 year warranty, an authorized or certified espresso service representative must perform the installation of this espresso machine. Site Preparation 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. - Page 8 Neutral Make sure that the On/Off electronics switch (red rocker) and the heating element breaker on the Synesso™ are in the OFF (0) position, then plug the power cord into the receptacle. IMPORTANT - If the voltage on the receptacle used is less than 210 Volts, it may be nec- essary to install an in-line Buck-Boost transformer to increase this voltage.

Page 12: Hydraulic System
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 componentry. - Page 13 HYDRAULIC SCHEMATIC--DUAL INLET Technical Manual...

- Page 16 (increasing pressure) or counter-clockwise (decreasing pressure). Water in Pump configurations: Until serial number 356, Synesso™s had a single inlet configuration as the stan- dard. After 356, the dual inlet configuration is the standard. Hydras have a separate pump and motor per group, therefore all Hydras come equipped with single inlet style pumps.
- Page 17 (Fill Line) Brew Gauge: The brew gauge reflects pressure in the brewing system. On a standard Synesso™, there is one gauge for the entire brewing system; on a Hydra, each brew tank has its own brew gauge. The gauge normally moves between 3-5 bar (resting pressure) to 9 bar (brewing pressure) and up to 12 bar (expansion pressure) at which point the expansion valve opens and releases the excess pressure.
- Page 18 Synesso™. Cold Water Valve: Synesso™ has 2 valves which provide water to the Americano (tea) spout: the hot water valve and the cold water valve. The cold water input allows the user to moderate the temperature at the spout to make drinks appropriate temperatures for their customers.
- Page 19 Water Inlet Components (cont.): Sight Glass: Connected to the steam tank by two tubes, the sight glass provides a visual representation of the level of water in the steam tank. It should be about 1/2 to 2/3 full during normal operation. This is a safety feature which enables the user to ensure that they have sufficient water levels in their steam system.
- Page 20 Brew tank: Synesso™’s brew tanks are solid stainless steel, welded internally and externally in order to be leak-proof and thermally stable. Each brew tank has its own isolated system from the water inlet. This allows the user to set different temperatures on each group, as well as function without a group in the system if something has gone wrong with a group.
- Page 21 Cuts power to the element if the temperature exceeds 280° F. Thermal probes: 2K ohm probes have been part of the Synesso™ machines since serial number 229 (prior to this, 100 ohm probes were standard). These probes are highly sensitive and send thermal data to the PID controller to control the temperature within the steam tank.

Page 23: Electrical System
Electrical System The electrical system in a Synesso™ is relatively straighforward. This chapter will cover the fundamentals of the electrical layout and function of the electrical features of the machine. SAFETY NOTE: Please use caution when working on any part of the Synesso™ electrical system. - Page 24 Electrical System Wiring schematic Technical Manual...
- Page 25 The electronics box, located underneath the machine, contains all the incoming and outgoing power to the Synesso™. Since the 2 boxes represented below (top: 3 group box, bottom 1 group) have many of the same components, they have been labeled with numbers for matching components and the descriptions follow in the next pages.
- Page 26 1. Brew relays: Control voltage to the brew tank heating elements. 2. Pump wires: Carries 220v to the pump motors from the electrical box. Contains 3 wires: black (110v), white (110v) and green (ground). A fourth wire (Red), is used for bypass system control when appropriate.
