primed, as indicated by pressure build-up on the reference instrument or the
instrument under test.
10. With the scissor handles (4) fully together, turn the selector (3) to the “High” position.
Operate the scissor handles (4) until the pressure is almost correct.
Note:
At higher pressures, it is easier to use short handle strokes.
11. To adjust the pressure to the correct value, turn the fine adjust vernier (2) clockwise
to increase the pressure or counterclockwise to decrease the pressure.
Note:
Initially, small pressure changes can occur (thermodynamic effects, the
seals settle, the hoses expand). The pressure will stabilize after a short time.
12. To fully release the pressure from the system, slowly turn the pressure release
valve (1) counterclockwise one full turn. This completes the procedure.
Note:
Careful operation of the pressure release valve (1) gives a controlled release
of pressure.
4. Fault Finding
1. If the system appears to lose pressure, repeat the above procedure. Make sure: there
is no damage to the seals, the adapters are tightened sufficiently, the pressure
release valve (1) is tightened sufficiently to seal.
2. Check the optional pressure release valve (10) setting, if fitted.
3. When in operation, if the fluid level in the reservoir falls by a large amount, this can
create a partial vacuum and affect pump performance. To prevent this, loosen the fill
plug (7) and let air into the reservoir.
4. If the PV 212 has not been used for a period of time, it may be difficult to operate on
the first stroke. It will become free after this.
5. For seal replacement refer to the service kit instructions.
If, for any reason, a fault occurs within the pump, it is recommended that the equipment be
returned to an appointed agent.
