SAFETY DEVICE AGAINST SIPHONING

There is a risk of liquid fuels escaping while the burner/pump is not operating due to the
pressure of the fuel column in the suction line if:
• the minimum liquid level in the tank is above the lowest point in the suction line,
• an feed line is below the highest level of the operating tank of a pump unit.
This is described as siphoning. A safety device against siphoning prevents this.
