To increase pressure

Turn the PRV adjusting nut (3) anticlockwise.

To decrease pressure

Turn the PRV adjusting nut (3) clockwise.

6.

After setting the PRV, hold the adjusting nut (3) in position and tighten 
the locking nut (2).

Note:

The locking nut has a left-hand thread.

7.

Check the operation of the PRV.  If necessary reset the PRV.

8.

Secure the locking nut by tightening the two locking screws (1).

Fault Finding

If the system pressure reduces, check the following:
1.

Check the selector valve   (7) is in the correct position and properly 
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.    Re-prime, and repeat.

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.
