4.1 DAF Saturator Preparation
Suggested procedure:
1) Remove the saturator from the packaging and visually inspect saturator unit for any obvious
damage or disconnected hoses. Reconnect any dislodged hose.
DO NOT use the unit if mechanical damage is apparent.
2) Connect the Saturator outlet and manifold to Jars tubing.
Check that the manifold outlet valves are all shut.
3) Open the water fill valve.
DO NOT undertake this step if the Saturator pressure is
above 0kPa
4) Fill the Saturator with clean water to the 0mL mark on the
level indicator.
Pour the water in as a steady stream - aim at the centre of the fill funnel.
Avoid filling rates that result in the funnel accumulating water. (lengthens filling time)
Fully open the air bleed valve to quicken the filling process (by releasing displaced air).
Always fill the saturator with clean/filtered water.
5) Close:
•
the water fill valve;
•
the air bleed valve;
•
manifold outlet valves remain closed.
6) Connect the compressed air line to the compressed air inlet.
Air pressure must not exceed 700kPa (102 psi).
7) Admit compressed air to pressurise the saturator (valve at the compressed air source)
Adjust the air pressure to the desired test pressure.
The regulator is adjusted by lifting the regulator knob till a click is heard or an orange band
is visible - then rotate the knob in respect to the “+” and “–” designation on top.
A typical starting point for saturator air pressure is 600kPa (87Psi). This can be adjusted up
or down as the saturator is brought up to the required pressure
