Fig. 4.6.A. Design of the waste channel
The main drain pipe must have the capacity to be able to handle the total output of all connected machines.
There must also be a hole every twenty meter in the drainpipe, fig. 4.6.B, pos. 1 to assure the good working
of the drain. This allows air in the main drain and facilitates drainage of the water flow. Every time a machine
is coupled on the drainpipe, the diameter of the tube or the width of the waste channel must be more. See,
fig. 4.6.B, D1, D2, D3.
The recommended drain pipes diameter are:
D1 = 75 mm / 3" for one machine
D2 = 100 mm / 4" for two machines
D3 = 125 mm / 5" for three machines
If the main drain cannot be sufficiently deodorized, install a deodorizer per machine.
