6.2 Water connection
6.2.1 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.

6.2.2 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.
