6.3 Complete oil filling
If no more pulses are generated, or if the pulse unit has been removed and refitted, the pulse unit must be
completely refilled with oil:
Oil order No. 925715, ESSO-UNIVIS HVI26, approx. 2 liters, temperature 20 ±5 °C
1
 Remove set bolt and ball
2
 Align both ends of the pulse unit as shown in the
picture (internal equalization hole is opened)
3

Use adapter to connect pulse unit to the
quick disconnect coupling.
 Close shutoff valve .
4

Set the working pressure to approx. 500 kPa.

Slowly open the shut-off valve all the way until
the gauge shows a negative pressure of
<10 mbar (-1 bar).

Wait approx. 2 minutes until the number of vac-
uum bubbles has reduced significantly.
 Slowly close the shut-off valve. The gauge
shows atmospheric pressure again. Missing oil
will be pressed back into the pulse unit.
 If necessary, repeat the last 3 rundown steps
until bubbles are reduced practically to zero.
