Open all control valves completely 2. Set all valves at the end receivers for the designed flow 3. Set the differential pressure using the knob - the number of revolutions is given in the table below 4. Measure the differential pressure Pinstal using the T550 device, connecting it to the measuring valve of the valve (Fig. 447 pos. 2) and to the measuring valve of the regulator (pos. 5). 5 / 7
