CAUTION
Incorrect alignment of the float switches may lead to malfunc-
tion!
To function properly, the float switches must have sufficient space to
float and lie flat on the surface of the water. Therefore, ensure correct
alignment of the pumps and floaters!
The level control device is factory-mounted and factory-set. The level control device may
slip from its mount during transport and lead to malfunction of the lifting unit. Therefore,
check the attachment and the cable length of the float switches prior to installation and
adjust if necessary.
