5.3. Pneumatic connection
Only connect components to the pump which are designed for
the pneumatic data of the pump (see Chapter4, Technical da-
ta).
If the pump is used as a vacuum pump, safely discharge the
pump exhaust.
Connecting pump
A marking on the pump head shows the direction of flow.
1. Remove the protective plugs from the hose connectors.
2. The accessory silencer/filter (where applicable) is put onto the
hose connector.
3. Connect the suction line and pressure line (tube ID 4 mm).
4. Lay the suction and pressure line at a downward angle to
prevent condensate from running into the pump.
