Set-up and putting into operation
37 / 72 V 1.0
• The discharge pipe should not be routed with tight elbows. The pipe must be routed above the backwater level
i.e. it must be routed continually rising to above this level and then directly to the collecting pipe in a loop.
• A shut-off valve should be fitted in the discharge pipe directly downstream from the integrated backwater flap.
• For the level control for emptying the collecting tank to function perfectly, it is absolutely necessary to route
the discharge hose between the collecting tank and the control unit without any kinks and on a steadily rising
gradient without loop.
• Cut the vertical venting muffs open and fit a DN 70 ventilation pipe to the collecting tank with the aid of the
flexible adaptor provided. The venting pipe must be installed blockage-free and secured against bending. The
pipe must be routed to the outdoors in compliance with the local regulations.
• The control unit provided must be attached frost-free and flood-protected on the wall in the building, in compliance
with local regulations.
• We recommend the installation of a manual diaphragm pump so that the collecting tank can be emptied in the
event of a power or pump failure. Drill open the 1“ connection on the tank for this. Install the manual diaphragm
pump in a 1“ riser pipe (pipe or hose). A backwater flap should be installed in the pipe above the manual
diaphragm pump to prevent the pumping medium flowing back. Route the riser pipe to the collecting pipe via
the backwater level.

operation and to operate it subsequently. The following specifications must always be heeded and checked:
• Type of set-up

• Minimum water cover / max. submersion depth
These specifications must also be checked following a longer period of standstill and any defects found must be
eliminated.
The operating and maintenance manual must always be stored near the machine or in a specially designated place
where it is always accessible for all members of the operating staff.
In order to avoid property damage or personal injury, the following points must always
be heeded when putting the system into operation:
The machine may only be put into operation by specially qualified and trained staff, taking the safety notes into
account.
• All members of staff who work on the machine must have received, read and understood the operating
instructions.
• Activate all safety devices and emergency-stop circuits before putting the system into operation.
• Electrotechnical and mechanical adjustments may only be carried out by specialists.
• This machine is only suitable for use under the given operating conditions.
Never allow the pump to run dry for longer periods (risk of overheating).
Before the system is put into operation, any pipe valves or shut-off valves must be opened.
