6. For an MVP Hydra machine, set up the 4 stage pressure ramping by following the instructions on page 19.
For an MVP machine, adjust the pump pressure by first shifting the brew group handle momentarily left two
times while in M mode to activate the pump/motor. Locate and read the pump pressure on the brew gauge
located to the right of the rightmost group. Then set the pump pressure to 9 bar with the following proce-
dures:
•
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 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. The factory set temperatures are 250°F for the steam tank and
203°F for each brew tank. Temperature readings for the steam and brew tanks are displayed on the handheld
controller. Temperature set points can be adjusted by following the instructions on pages 40 and 41. Once
the readings are at the set temperature, the machine is fully operational and ready for use.
Note : As the brew groups heat, the needle of the brew pressure gauge(s) may rise above 11 bar. There is an
expansion valve used to control the maximum pressure achieved. MVP Hydra machines have a separate ex-
pansion valve and pressure gauge for each group present. MVP machines have one expansion valve for the
entire brew system. Each expansion valve is factory set to bleed off pressure at 11
- 12 bar. If the needle rises
above 12 bar on the pressure gauge, the expansion valve should be adjusted to bleed off pressure near 11 - 12
bar so that the maximum pressure reading of the brew gauge cannot exceed 12 bar. The expansion valve re-
quires periodic adjustment throughout the lifetime of the machine to ensure that the pressure in the brew
system is not able to increase above 12 bar.
8. Before brewing your first espresso shot or using the steam wands, it is a good idea to purge the groups and
the steam wands.
•
To purge the groups, shift each group head handle left to activate the group. Let the group run for several
seconds. Then turn the group off by shifting the handle to the right.
•
To purge the steam wands, position the wand tip into the drain tray. Activate the steam wand by pulling
the steam wand handle toward you. Caution that the steam expelled as well as the area of the wand at or
near the tip can be hot enough to cause burns. After allowing steam to escape for several seconds, turn
the steam off by moving the handle away from you into the off position.
Note: The steam wands should be purged before and after 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 flavor
. These issues are fully preventable by habitually purging the wands, as described above, and keep-
ing the machine up - to - date on preventative maintenance.
