Safety guidelines
- The pump must always be installed below the liquid level.
- The suction line must be as short and direct as possible.
- Avoid elbows and the enlargement of the diameter in the pipeline to avoid air stagnation.
- The size of the suction and delivery lines must be AT LEAST equal to the nominal diameter of the size of the relevant opening.
- The suction line must be free from air leaks.
- Avoid, if possible, elbows and narrowing in the pipeline on the delivery line, this is to limit possible loss of pressure.

Water/air bleed
- Install a breather pipe (Item 2 Fig. 2) in one of the delivery retaining plugs placed on the pump.
The tube diameter must be 6 mm or 1/4".
- Choose the plug located in the highest point according to the installation position of the pump (Fig.
9
) in order to eliminate any
air trapped in the pump and to allow a minimum motion of the liquid also when the control unit connected to the pump is not
spraying.
