Jets installation parts

Follow the instructions from Jets® when installing horizontal piping for maximum efficiency and trouble-free service.
These important instructions apply when planning both rising and falling systems.

When planning a vacuum piping installation, it is important that the number of wastewater units matches the dimensions of the piping. Table 1 shows
the recommendations to be followed for maximum efficiency in the vacuum system.
Jets recommends the use of vacuum-approved pipes from Poloplast.

Piping requirements:
– Suction side 50mm vacuum-approved pipes e.g. Poloplast
– Pressure side PEM hose 32mm

VOD vacuum side, fall and transport in horizontal pipes

Follow the instructions from Jets® when installing horizontal piping for maximum efficiency and trouble-free service.
These important instructions apply when planning both rising and falling systems.
Vacuum piping slope
● Horizontal piping systems should be installed in accordance with general principles with a slope downwards to the Vacuumarator® pump. The slope should
be 1:100
● Install transport pockets if the distance exceeds 6 m.
● Outlet pipes from wastewater sources, such as toilets, urinals and squat toilets, should be directed downwards to avoid backflow.
● Transport pockets are not needed as long as the slope is 1:100 and the distance does not exceed 6 m.

VOD vacuum side, transport pockets
In plants where the slope cannot be guaranteed, transport pockets must be installed if the horizontal length exceeds 6 meters. This is required to
convert the wastewater into sludge, control the vacuum flow and help prevent backflow.

Note! The Vacuumarator® pump must always be installed at the same or lower level than the waste water sources (i.e. toilet)
(A) Lift height, max 800 mm
(A) 4 x 45° bends

VOD/VIP vacuum side, rising pipes, multiple toilets
Waste water connections and Vacuumarator® pump at the same level: rising horizontal pipe (lift)
● Make sure that the Y-branch fittings (B) are mounted in the direction of flow.
● Always connect the gooseneck (A) from top to bottom to the horizontal pipe.
● If you want to run rising pipes to a Vacuumarator® pump, a 90º pipe bend (2 x 45° bends) is required from the toilet/waste water source.
● Note: If it is not possible to lay the pipes with the necessary slope, a transport pocket must be included centrally along the pipe. This applies to pipes that are
more than 6 m long.
