Setting the DigiZone
™
Temperatures
1. Select the desired zone by pressing the ZONE button. Press and hold the SET button to check the
current set point.
2. To adjust a zone temperature, use the ZONE button to cycle to the zone you want to adjust.
3. Press and hold the SET button while using the ARROW keys to adjust up or down to the desired
temperature.
4. The heating element has 2 separate coils. Zone 4 is the primary coil and it is recommended that you
set the temperature to read about 1.2 to 1.4 Bar (approximately 250°F – 255°F) on the steam gauge.
Zone 5 should be set about 5°F to 8°F lower, so the 2
nd
coil is only active when needed.
Toggle Display Between C and °F
Press and hold the Down Arrow and the Zone Button until you hear a beep. It is encouraged to set and
adjust your temperatures in °F as it is the more accurate scale. (* for s/n 0303 forward)
Steam Tank Pressure & the Relationship to Temperature
• Pressure = Bar or PSI (pounds per square inch)
• 1 Bar = 1 Atmosphere = 14.7 PSI at sea level
Temperature as it Relates to Pressure in the Steam Tank:
Temperature Bar PSI
230° .40 to .50 6 to 8
240° .75 to .85 10 to 12
250° 1.10 to 1.20 15 to 17
260° 1.40 to 1.60 23 to 25
270° 1.80 to 2.00 30 to 32
Removal of Right Hand Side Panel
CAUTION: This should ONLY be done by Qualified Personnel
Use a 5/8” wrench, remove the 4 nuts & O-rings; the steam lever will stay attached to the panel
1. Adjust the expansion valve – locate valve, use 12mm wrench, loosen or tighten to relieve pressure
at 12 Bar.
2. Turn off the steam valve – locate the inline ball valve, turn stem clockwise with an adjustable
wrench.
3. Rebuild the steam valve – purchase the kit from Synesso and install it.
4. Adjust hot water mix valve – turn handle clockwise to close valve completely, giving you steam tank
water only, turn handle counterclockwise ¼ turn (this adds cold water), measure water temperature
at the hot water spout, continue with ¼ turn increments until desired temperature is achieved.
5. Locate the drain box, remove and clean.
Bean Grinding
1. For best results, use fresh coffee.
2. Understand the properties of the coffee roasts you have chosen.
• Generally, light roasts brew at hotter temperatures than dark roasts
