Installation Instructions

Installation:

Stop Silent Light can be installed at any angle, horizontal to vertical, both at the inflow and outflow of the inspection manhole. The steeper the slope, the better is the self-cleaning effect. A minimum constant slope of 2% in front of the valve is recommended for the proper functioning of a Stop Silent Light valve in sewage water.

Installation Inflow:

Einsetzen des Ventils / Insertion de la vanne / Inserting the valve

Before installation, completely loosen the clamping mechanism and moisten the valve surface with water. (Possibly soap water)

Einsetzen des Ventils / Insertion de la vanne / Inserting the valve

Insert the valve until the sealing lip fits completely inside the pipe. When inserted correctly, the valve should sit within the pipe as shown in picture (c).

Einsetzen des Rückschlagventils / Insertion du clapet anti-refoulement /Insertion of the check valve

Tighten the screw in direction of the arrow with the original tool. To guarantee optimal functioning, the bolt has to be centred in the upper part of the pipe.

Installation Outflow

Einsetzen des Ventils / Insertion de la vanne / Inserting the valve

Before installation, completely loosen the clamping mechanism and moisten the valve surface with water. (Possibly soap water)

Einsetzen des Ventils / Insertion de la vanne / Inserting the valve

Push the valve into the pipe until at least the expander clamp is completely in the pipe.

Einsetzen des Rückschlagventils / Insertion du clapet anti-refoulement /Insertion of the check valve

Tighten the screw in direction of the arrow with the original tool. To guarantee optimal functioning, the bolt has to be centred in the upper part of the pipe.

Functional check and maintenance:

Used with sewage water

Newly installed valves have to be checked for function and sedimentation after 4-6 weeks

The valve should be checked twice a year.

Open the cover of the inspection shaft and descend. Flush the toilet several times while flushing down toilet paper. Observe whether flushed water including paper passes the valve. Check the membrane for brittelness or flexibility. If necessary, clean the membrane with clean water.

Used with rainwater:

The procedure is the same as with sewage water.

The valve should be checked once a year.

IMPORTANT: You must not use a high-pressure cleaning device
