Installing the test unit
1 Connect the Tester to the circuit (see inside back cover for port sizes). The preferred flow
direction is indicated by the larger arrow on the panel. Use hoses and fittings of sufficient
diameter for the flow being tested. Avoid restrictions at inlet and outlet ports of the Tester.
Also avoid sharp bends because high pressure hoses will deflect and straighten under
pressure.
2 Ensure that the pressure loading valve is fully opened by turning the knob counter
clockwise.
3 Switch the unit on. On digital models if the display flashes, or on analogue models if the
needle points to the symbol, then the battery needs replacing.
4 Select the desired test using the front panel controls (not applicable on 1 series)
5 When low pressure testing is required, connect the optional low pressure gauge with
automatic cut-out valve to the tester block.
Note: the test point can be connected by hand at full pressure.

on. First switch off the tester, plug in the Tacho and then switch the tester back on. Only
