6.3. Connection of Machine Outlet to Water Trap and Sewer Pipe
Connecon of water trap and sewer pipe to the delivered disposer must be done by an authorized
installer of sewer supply and in accordance to valid local regulaons. The water trap is not included in
standard delivery but is available as an opon from Disperator.
6.3.1. Dimensions
The water trap and the sewer pipe must have the same dimensions as the outlet ange of the
disposer (i.e. DN50 for models 510, 515 and 520, and DN65 for models 530, 550 and 575), in
order to allow free wastewater ow from the disposer. No throling in the water trap and sewer
pipe may exsist.
6.3.2. Depth and Threshold of Water Trap
The depth of the water trap (measurement “d” in gure below) must be as small as possible in
order to obtain the best possible ow with the largest amounts of food waste. The water trap
must also be deep enough, so that the water threshold “d1” is approximately 100 mm for models
510, 515 and 520 and approximately 160 mm for models 530, 550 and 575.
6.3.3. Curves and Bends
The water trap, and all bends in the sewer pipe, must be drawn without sharp bends or curves,
according to local standards. The distance “k” in the gure below must be 100-120 mm for
models 510, 515 and 520 and 130-150 mm for models 530, 550 and 575.
6.3.4. Level Dierence of Water Trap
The level dierence (measurement “n” in gure below) must be at least equal to the inner
sewer pipe diameter, which is dependent on the wall thickness of the water trap (however
approximately 50 mm for disposer models 510, 515 and 520 and approximately 65 mm for
models 530, 550 and 575).
6.3.5. Slope of Sewer Pipe
The inclinaon of the sewer pipe (measurement “f” in gure below) should normally be 2:100
(minimum 1,5:100, maximum 3:100). Horizontal sewer pipes must always be avoided. Also
greater inclinaon than menoned above must be avoided, as the water then ows faster and
away from the waste.
6.3.6. Vacuum Evacuation
For installaons where the disposer is evacuated by means of a vacuum, a water trap must not
be connected to the outlet of the disposer. Instead, the disposer is connected directly to the
collecon tank of the vacuum system. It is important that the sewer pipe, between the disposer
and the collecon tank, has a venlaon pipe that is always open (as shown in the gure below).
A venlaon pipe must be ed even if the collecng tank has automac airing.
