11 Adjustments (continued) Use 1mm wrench to turn the safety screw counterclockwise to loosen it. Use 10mm wrench to turn the adjustment screw counterclockwise to decrease the water pressure. Figure O Figure N Steam Boiler Pressure Calibration WARNING: SHOCK HAZARD Unplug machine before adjusting steam pressure. Steam boiler pressure is controlled by the pressure switch. The pressure inside the boiler continues to rise as the water is heated by the heating elements. Reducing pressure will reduce temperature, while increasing pressure will increase temperature. The steam boiler has been factory adjusted to 1 bar, (the recommended pressure). Check if the pressure on the pressure gauge is 1 bar or in the blue zone (1-1. bar) (see Figure P). if so, you don t need to adjust the pressure. If there is a need to change the pressure, follow below procedure for calibration: Steam Pressure 1.0 bar Figure P 1. Turn off machine. 2. Remove top cover of machine, and locate the pressure switch in the center, back area (see Figure Q). 3. Use slotted screwdriver to adjust the pressure as shown in Figure R. Turn screw clockwise to increase pressure, or counterclockwise to reduce pressure. A complete screw turn results in about 0.1 bar variation. Figure Q Figure R ET1 Espresso Machine Grindmaster 11

12 Draining CAUTION: BURN HAZARD Dispenser surfaces and water inside dispenser are very hot. Use caution when draining unit to prevent burns. CAUTION: BURN HAZARD Never turn on drain valve when there is pressure in the boiler. If espresso machine will not be used for an extended period, will be stored, or transported, drain tank to prolong life and prevent damage from freezing. 1. Turn off the machine, and release all the pressure from boiler by turning on the steam knob(s). 2. After the steam is completely released and the pressure on steam boiler pressure gauge reads 0, remove drain tray and locate drain valve under drain tray.
