Problem

Remedy
Fluid escapes (equipment is
leaking).
The equipment has been
damaged by frost.
Replace the equipment with a new one.
When shutting down the installation
make sure that all lines and the
equipment are completely drained.
If faults occur that are not listed above or cannot
be corrected, please contact our Technical
Service or authorized agency in your country.
Retighten the stuffing-box packing.
Retighten the stuffing-box packing if the equipment
is leaking fluid at the float-lifting lever.
Tighten the stuffing-box packing until the following
requirements are met:
The stuffing box must not leak.
The movement of the float-lifting lever must not
be impaired by the stuffing box.
Fasten the hexagon-head cap screw on the
float-lifting lever (15).
Allow the fluid to flow through the equipment.
Move the float-lifting lever several times over
the full length.
Make sure that the float-lifting lever can move
freely.
If necessary, slightly loosen the hexagon-head
cap screw.
The stuffing-box packing is adjusted correctly if no
fluid escapes and the float-lifting lever moves freely.
If you cannot prevent the stuffing-box packing from
leaking fluid replace the whole float-lifting lever.
To do so follow the instructions given on
page 31.
