Fault Finding

If the system pressure reduces, check the following:
1. Check the selector valve
tightened.
2. Allow sufficient time after pressure generation for the temperature to
stabilize. The larger the system volume, the longer the time for
thermal stability.
3. Check the adaptors, flexible pipe and connections between the pump
and equipment under test for leaks. Tighten any loose joints and
replace any seals that are worn or damaged.
4. In hydraulic mode, if the volume adjuster can be wound fully in, but
maximum pressure cannot be achieved, there is probably air trapped
in the system.
5. Check PRV pressure setting.
If, for any reason, a fault occurs within the pump, it is recommended that the
equipment be returned to an appointed agent.
