en
point compared to the floats that control the pumps. Make sure that the seal is correctly positioned on
the outside to prevent spills from the basin. Adjust the cord, initially, so that the length that is free to
swing, including the float, is no longer than 260 millimeters. Later, when the unit is started for the first
time, the length of the cord can be adjusted based on the actual requirements of the system. An audible
or visual alarm with very low voltage can be connected to the Lowara control panel.
For further information, refer to chapter 12.
6.2.5 Lifting station with one three-phase pump (with control panel)
The three-phase electric pump and the control float must be connected to the control panel. The float
switch is normally electromechanical type (see chapter 5.5). The related electric cord can be threaded
through the seal on the cover, alongside the pump’s power cord, or you can use one of the blind holes in
the upper section of the basin and one of the cable glands provided with the lifting station. Secure the
float switch to a side wall of the basin using one of the fastening brackets provided with the lifting station.
Make sure that the seal is correctly positioned on the outside to prevent spills from the basin. Adjust the
cord, initially, so that the length that is free to swing, including the float, is no longer than 260 millimeters.
Later, when the unit is started for the first time, the length of the cord can be adjusted based on the ac-
tual requirements of the system. In any case, the minimum level of the liquid must not be lower than the
pump’s suction port or the pump will de-prime.
Read the instructions / wiring diagrams for the electric panel before proceeding with the installa-
tion.
Mount the electric panel on a wall or other support. Adjust the thermal relay to the value of the rated cur-
rent of the pump.
If you require a high level alarm (warning that the liquid level inside the basin is too high), you have to in-
stall an additional float switch and an audible or visual alarm. The float switch is normally electromecha-
nical type (see chapter 5.5). The related electric cord can be threaded through the seal on the cover,
alongside the pump’s power cord, or you can use one of the blind holes in the upper section of the basin
and one of the cable glands provided with the lifting station. Secure the float switch to a side wall of the
basin using one of the fastening brackets provided with the lifting station. It must be secured at a higher
point compared to the float that controls the pump. Make sure that the seal is correctly positioned on the
outside to prevent spills from the basin. Adjust the cord, initially, so that the length that is free to swing,
including the float, is no longer than 260 millimeters. Later, when the unit is started for the first time, the
length of the cord can be adjusted based on the actual requirements of the system. An audible or visual
alarm with very low voltage can be connected to the Lowara control panel.
