4.1 Before Testing
4.1.1 Set up the Hydraulics Bench as per Hydraulics Bench Manual
4.1.2 Place Flow on the Bench, adjusts the screw at the base for level and connect water supply hose the Bench to the test apparatus
4.1.3 open the discharge valve of the test set. the vent valve on the manometer top manifold and att the hand air
4.1.4 open the measuring tank discharge valve and closed the Hydraulics Bench flow control valve
4.2 Start the Test
4.2.1 Start the Hydraulic Bench pump and slowly open the Bench flow control valve until air bubbles a completely removed from the test set, then reduce the flow rate to about 10 lpm on the flow meter
4.2.2 required flow rate. they are too hig observe water levels in the manometer and ensure that all levels can be observed. If pump air into the manometer head manifold. If they are too low slightly close the test equipm discharge valve or bleed air out from manometer head manifold by vent valve. (See Addendum 1 Water Manometer.)
4.2.3 Record manometer levels for each flow measuring device.
4.2.4 Record the measuring tank volume and time. (See Hydraulics Bench Manual)
4.2.5 Repeat the 4.2.2 to 4.2.3 for flow rate of 15, 20, 25 and 30 lpm on flow meter
