1.2

Unscrew valve cap (9) from filler connection (2)

New version.

2

Completely drain pressure reservoir by operating the valve element (5 or 8)

3

Unscrew valve element (5 or 8) from filler connection (2)

6

Inflate pressure accumulator bladder to specified pressure

If this pressure is too high, then this can be corrected by pressing the drain button (3) on the pump (4).

Set specified pressure roughly 0.2 bar higher, because a slight pressure loss of this magnitude is unavoidable because of technical reasons when detaching the filling hose of the pump (4) from the filler connection (2) .

7

Unscrew filling hose of pump (4) from filler connection (2)

Note down set pressure (minus 0.2 bar).

Checking

8

After a waiting period of 5 minutes, screw filling hose of pump (4) onto filler connection (2)

Observe waiting time. Otherwise the test result may be faulty.
