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. The machine
’
s auto
-
fill feature will activate and the steam tank will begin filling.
3.
Bleed the air from the group heads by running each group until water flows without sputtering.
4.
When the steam tank has stopped filling, set the heating element breaker to the ON position. The machine
will begin heating to the set temperatures.

To 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). Make adjustments while running the shot programs to see the
current pump pressure. Once the desired pressure is reached, retighten the lock nut.

Please allow at least 30 minutes of

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 be-
fore the steam tank is at an operational pressure and will stop at 1.3 bar when the factory set tempera-
ture of 250°F is reached. The factory set temperatures for each brew tank is 203°F. 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 19 and 20. 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 may rise above 11 bar. There is an ex-
pansion valve used to control the maximum pressure achieved. This valve is positioned to bleed into the
drain tray of the machine and is accessible for adjustment from the front of the machine without having to
remove machine panels. The 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 requires 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.
7. Once the steam pressure gauge reads at or above 1.1 bar, you may purge the steam wands. To purge the
steam wands, first position the wand tip into the drain tray. Activate the steam wand by pulling the steam
wand handle toward you. After allowing steam to escape for several seconds, turn the steam off by returning
the handle to the resting position.
