Inspection
The system must be checked once every month by the opera-
tor through observation of the switching routine for operational
ability and leaks.
Caution
Disconnect the unit from the mains during all servicing work! Heed
safety instructions!
All the servicing and maintenance work described below may only
be carried out by authorised qualified personnel. Repairs may only
be carried out by the manufacturer.
Servicing
During servicing of lifting stations, EN 12056 must be followed.
Servicing work must be carried out by authorised qualified
staff. The following tasks have to be carried out:
• Visual inspection of the pumps and fitting parts
• Check the pump for free movement, wear and deposits
• Check the connection pipes for mechanical damage
• Check the chamber system for heavy soiling, clean if neces-
sary. Sharp cleaning tools (e.g. pointed spades) are not sui-
table since they may damage the chamber.
According to EN 12056, servicing must be carried out at the
following intervals at least:
• Every three months for commercial applications.
• Every six months in multi-family homes.
• Every year in single family homes.
Special servicing instructions for chamber system LW 600
All service / maintenance work ist to be carried out outside the
chamber.
No-one may climb into the chamber LW 600. The pump brackets
could otherwise become damaged, for example.
• The pump is removed by opening the red one-hand snap closure.
The pump including pressure pipe is removed from the chamber.
• The backwater flap can be removed using the black lever.
Caution: The complete pressure pipe contents will drain out in
this case.
Recommendation: If the backwater flap is to be serviced, remove
the pump completely with the flap, this makes it easy to empty
the pressure pipe. When servicing the pump, only open the red
snap closure, in this case the pressure pipe will not be emptied.
When servicing the pump with backwater flap, only the black
snap closure is to be opened (see Fig. 17).
• The base of the chamber must be checked for sludge and cle-
aned from above if necessary, damage to the chamber inc. ins-
tallations must be avoided.

Pump
Follow the safety instructions concerning weight / lifting the pump!
For all work on the pump, we recommend lifting the pump out
of the chamber (after disconnection from the mains), cleaning it
off roughly (e.g. hosing it down) and setting it down on a clean
surface for inspection work. Work on the pump other than that
described must not be carried out.

rough the connection length (see dimensional drawing in section
2.3.1)
height (see dimensional drawing in section 2.3.1.).
length of the floating cable must be checked. If the floating cable
is too long it prevents switch-off, since the floating switch is then
on the base of the chamber.
