Turn to position „Start“
Activate spray handle/open outlet point
In the case of newly installed systems, or if the pipeline and the pump have been drained in any other
way, the system should be vented by starting the pump and then let the water run freely at each outlet
point of the pipeline in turn.
When connecting the high pressure hose directly to the machine, the system should be vented by starting
the pump and activating the trigger of the spray handle without the spray lance attached.
Let the water run until all air has escaped from the pump (regular water flow).
KSA-2
In the case of newly installed systems, or if the pipeline and the pump have been drained in any other
way, the system should be vented as follows:
1. Start pump no. 1 and let the water run from an outlet point of the pipe-line.
When connecting a high pressure hose directly to the machine, activate
the trigger of the spray handle without the spray lance attached.
Let the water run until all air has escaped from the pump (regular water
flow).
2. Stop pump no. 1. Then start pump no. 2 and let the water run from an
outlet point of the pipeline. When connecting a high pressure hose directly
to the machine, activate the trigger of the spray handle without the spray
lance attached. Let the water run until all air has escaped from the pump
(regular water flow).
3. Vent the pipeline by starting a pump and letting the water run from each
outlet point (begin with the outlet farthest from the machine) until all air has
escaped from the system.
