In cases of a 4-meter difference between the evaporator and condenser units of a split, the evaporator unit being at a lower level than it should be done?

A siphon must be installed in the suction line for every 3 meters of unevenness. In the installation where the evaporator unit is located and the condensing unit on the same level or the evaporator unit is at the upper level, a siphon followed by an inverted "U" must be installed immediately after the evaporator unit is discharged into the suction line. Should be in the same plane as the highest point on the evaporator.
