  • Page 3: Introduction

    This manual applies to all Synesso™ models: Cyncra, Sabre, Hydra and Hybrid machines. The Cyncra is Synesso’s™ manual machine, available in 2 and 3 group models. The Sabre is a volumetric machine, also available in 2 or 3 group models. Hydra machines have an individual pump and motor per group head and can accommodate 4-stage pressure ramping on all groups.

  • Page 4: Safety Warnings

    The hot water mix valve can be adjusted to deliver water as hot as 212°F (100°C), which can cause severe burns: please use caution when activating this water source.     Safety Label Locations: Synesso™ complies with UL regulations by posting the following labels on its machines: Electrical box: California only:  ...

  • Page 5: Safety Precautions

    Safety Precautions: Espresso machines have numerous potential hazards, and it is of paramount importance to Synesso™ that people servicing our machines take all necessary precautions to ensure their personal safety. When working on the machine’s boilers (unless otherwise instructed in the directions): Turn the machine off and shut off the incoming water supply.

  • Page 11: Electrical Requirements

      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.

  • Page 12: Hydra/Hybrid

    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.

  • Page 13: Hydra Bypass Installation And Setup

    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.

  • Page 14: Operation

    Once the desired pressure is reached, retighten the lock nut. 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.
  • Page 15 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.
  • Page 16 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.  ...

  • Page 17: 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.

  • Page 21       Pump configurations: Until serial number 356, Synesso™ ma- chines had a single inlet configuration as the standard. After 356, the dual inlet con- figuration is the standard. Hydras have a separate pump and motor per group, there- fore all Hydras come equipped with single inlet style pumps.

  • Page 22: Water Inlet System

      Brew Gauge: The brew gauge reflects pressure in the brewing system. On a Cyncra or Sabre, there is one gauge for the entire brew system; on a Hydra, each brew tank has its own brew gauge. The gauge normally moves between 3-5 bar (line pressure) to 9 bar (brewing pressure) and up to 12 bar (expansion pressure) at which point the expansion valve releases the excess pressure.
  • Page 23   Cold Water Valve: Synesso™ machines have 2 valves which provide water to the americano / tea spout: the hot and cold water valves. Mixing in cold water allows the user to moderate the temperature at the spout. Boiling water is not appropriate for all beverages.

(Page 22).     Steam Inlet Water Control Valve: When the upper level probe (Page 25) detects an absence of water, the control board will send a signal to open this valve and allow water into the steam tank.

  • Page 25: Water Outlet System

      Brew Tank: Synesso’s™ brew tanks are entirely stainless steel, welded internally and externally to be water tight and thermally stable. Each brew tank has its own temperature probe and element which allows the user to set different temperatures on each group, as well as operate without a group if a serious service issue arises.

      SAFETY NOTE: Please use caution when working on any part of the Synesso™ electrical system. Live current poses the risk of electrical shock, harm, permanent injury or death. Take all appropriate precautions, including turning off the machine, breaker, and/or unplugging the unit prior to working on the machine.

        In an effort to prevent damage to machines and to help operators troubleshoot issues, Synesso™has engineered several safeguards into the programming. These codes will help users identify operational issues with the machine as well as automatically prevent greater problems from occurring. By understanding these codes, operators can remedy issues more quickly.
