1.Relieve accumulator air pressure to zero using accumulator air pressure regulator (106).

2.Install material feed line to accumulator material inlet (143a) on refill valve (143).

CAUTION

The refill valve has an open port on one side and a closed port on the other. Do not remove the plug opposite the material inlet (143a). The valve will not function properly if the plugged side of the valve is changed.

3.Place a waste container below the ball valve (109).

4.Open the ball valve (109).

5.Slowly increase air pressure until the accumulator begins filling slowly.

6.Close the ball valve (109) when material begins to spill into the waste container.

The vent tube is now full. The accumulator will fin- ish filling and it will stop when the fluid level reaches the high level sensor.

7.Use accumulator air pressure regulator (106) to adjust to desired accumulator air pressure.

Accumulator air pressure should be set to the low- est possible setting to adequately run the accumu- lator.

8.See the PR70 and PR70v Operation manual refer- enced at the beginning of this manual to adjust dis- play module run settings for the accumulator.
