CONNECTING THE TESTER
Connect the tester to the service outlet via a fire hose to the inlet connection. The tester is now ready
for use.
4.
STATIC & RESIDUAL (DYNAMIC) PRESSURE TEST
For Static Pressure Test
If fitted (as optional extra) CLOSE the outlet valve on the tester. If valve is not fitted, cap the
outlet with a blanking cap.
For Residual (Dynamic) Pressure Test
A diffuser should be fitted to the valve & then the valve partially opened.
5.
Open the service outlet valve and the
‘static’ (no flow) pressure will be indicated on the pressure
gauge.
6.
FULL (UNRESTRICTED) FLOW TEST
Continue on from step 4 (above) and open the test box outlet valve. The flow meter will now
Indicate the available flow in L.P.M. (or LPS if supplied). During this test the pressure gauge will
indicate zero or just above zero.
7.
FULL RESTRICTED FLOW TEST
After selecting and fitting the appropriate hosereel nozzle repeat the test as in step 5 (above). The flow
meter will once again indicate the available flow rate via this nozzle and the pressure gauge will
indicate at what pressure.
8.
OPERATION OF DIGITAL DISPLAY TOTALIZER (type 8150)
The 8150-1 display shows the flow rate in large numerals and a totalizer value in smaller
numerals. Any one of three different totalizers can be selected as the standard display.
Press the UP or DOWN keys to scroll through all three totalizer values during normal
operation.
