ISCHARGING OF THE SAMPLE
Close the sampling valve on the tank, then open both inlet and outlet valves to remove any pressure
inside the hoses and the GMD. Then disconnect the inlet hose (3), place the outlet hose (5) to the
drain and turn the device upside down. At the same time hold the inlet hose (3) 10 cm over the
device. Check visually if the transparent vessel (6) is empty.

sample with the new one by leaving the new beer flowing through the GMD about 30 s.
If you have finished measurement, clean the device. Rinse the device with clean water.
