• Clockwise rotations increase the hot water temperature.
• Counterclockwise rotations decrease the hot water
temperature.
3. Verify the temperature at the hot water tap with a digital
thermometer.
ADJUST PRE-INFUSION PRESSURE
Machines are tested at 2.5 bar (~36psi). Recommended operating
pressure is between 2.5 and 4 bar (~ 36 to 60 psi).
REQUIRED TOOLS
• Slot screw driver
• Small crescent wrench
• Phillips Head screw driver
