Electrical Wiring; Notes On Safety; Control Box - Chappee TIGRA 2 CF 510 Installation, Use And Maintenance Instructions

In the vacuum systems (Fig. 13) the return line should terminate
within the oil tank at the same level as the suction line.
In this case a non-return valve is not required.
Should however the return line arrive over the fuel level, a
non-return valve is required.
This solution however is less safe than previous one, due to the
possibility of leakage of the valve.
H-H1 = Difference of level
= Max. lenght of the suction line
L
I.D. = Interminal diameter of the oil pipes
