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.
  • Page 9: Plumbing Requirements

    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-fill system for the steam tank functioning properly. Please ensure that the incoming water meets this requirement or contact Synesso for alternative methods of boosting water pressure.
  • Page 10: Electrical Requirements

    ELECTRICAL REQUIREMENTS All Synesso™ machines are rated to operate on 220 VAC with a 50 or 60 Hz frequency, single phase. Ma- chines will operate between 208 V and 240 V. Listed amp ratings are all measured at 220 V. Incorrect voltage can cause malfunction or damage to the ma- chine.

    START UP Start-Up Instructions 1. Connect the water lines and the drain hose. Turn the water ON. Water will begin to flow into the brew groups. 2. Ensure the heating element breaker switch is in the OFF position. Then switch the red electronics On/Off switch to the ON position.
  • Page 18 Once the desired pressure is reached, retighten the lock nut and turn off the group. 7. 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 before the steam tank is at an operational pressure.

    4 STAGE PRESSURE RAMPING SETUP - MVP HYDRA MVP Hydra Bypass Pump and Motor Assembly MVP Hydras come with a bypass pump and mo- Pressure Regulator for tor assembly that allow for four-stage pressure Preinfusion Pressure ramping. The shot begins with preinfusion. Low pressure water saturates the puck, swelling it to reduce channeling.
  • Page 20: Operation

    1. Select the desired 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 and bottomless portafilters can be used with double (14g) or triple (18g or 21g) baskets to brew double or triple shots.
  • Page 21 OPERATION Brewing in M (Manual) Mode: Manual mode allows the user to cycle through each stage of pressure profiling, from the start of the shot to the end, manually. To brew a shot in M mode, follow the instructions below: 1.

    PROGRAMMING Menu Level 2: Temperature This is the temperature display screen. Line 2 indicates the temperature scale that you are currently in (Fahrenheit or Celsius). Line 4 indicates the operation status of the machine’s brew valves. Setting the brew valve function to [ON] will activate the brew valves, allowing the pressure to be bled from the brew tanks.
  • Page 53: Brew & Steam Offsets

    This offset should not be altered without thoroughly testing the puck temperature, as mentioned above. Synesso keeps a log of the factory offsets for each machine. Contact Synesso Technical Support if you need to obtain the original factory-determined offset values.
  • Page 54 Add time here if the machine is in an unstable installation such as a food truck or catering cart. There is no need to drop this time below 5 seconds. Contact Synesso Technical Support if you need to obtain the original, factory-determined offset values. To cycle to the next display screen, press the down button.
  • Page 55: System Clock

    PROGRAMMING Menu Level 2: System Clock This is the system clock screen. Line 2 allows the operator to set the local time in a 24 hour format. Line 3 and 4 allow the operator to set the current date. The date and time are used for both the error log and the power saving mode. A small battery on the power board should keep the clock and calendar running if the machine loses power, but it will need to be re- placed eventually.
