6.3.
Water Trap and Drain Pipe
The drain connection of the delivered disposer must be done by an authorized installer of sewer
supply and in accordance to valid local regulations. The water trap is not included in standard delivery
but is available as an option.
6.3.1.
Dimensions
The water trap and the drain pipe must have the same dimensions as the outlet flange of the disposer
(i.e. 2” for models 510A-520A and 2½” for models 530A-575A), in order to allow free waste water flow
from the disposer. No throttling in the water trap and drain pipe may exsist. Larger dimensions must
also be avoided as this will reduce the speed of the waste water flowing from the disposer.
6.3.2.
Depth and Threshold of Water Trap
The depth of the water trap (measurement “d” in figure below) must be as small as possible in order
to obtain the best possible flow with the largest amounts of food waste. The water trap must also be
deep enough, so that the water threshold “d1” is approximately 80mm for models 510A–520A and
160mm for models 530A-575A.
6.3.3.
Curves and Bends
The water trap, and all bends in the drain pipe, must be drawn without sharp bends or curves,
according to local standards. The distance “k” in the figure below must be 100-120mm for models
510A-520A and 130-150mm for models 530A-575A.
6.3.4.
Level Difference
The level difference (measurement “n” in figure below) must be at least equal to the inner drain pipe
diameter, i.e. 2" for disposer models 510A-520A and 2 ½” for models 530A-575A.
6.3.5.
Slope of Drain Pipe
The slope of the drain pipe (measurement “f” in figure below) must not be less than 2:100. When the
rate of flow of food waste is large, and/or where the distance from the disposer to the floor drain is
great, a slope of (but not exceeding) 5:100 should be maintained.
Installation of horizontal drain pipes
must be avoided at all times.
6.3.6.
Vacuum Evacuation
For installations 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 collection
tank of the vacuum system. It is important that the drain pipe, between the disposer and the
collection tank, has a ventilation pipe that is always open (as shown in the figure below). A ventilation
pipe must be fitted even if the collecting tank has automatic airing.
