FLOW
Drain connection
Drain valve
Connect a 76 mm (3") pipe or rubber hose to the machine’s drain pipe, ensuring a downward flow from
the machine. Avoid sharp bends which may prevent proper draining.
The drainage pipe should be located over a floor drain, drainage channel.

Recommended distances:
o x1 = freestanding machines – see figure 1, “G” + “O”
rigid-mount machines – see figure 2, “G”
o x2 = >100 mm / 3.94"
o x3 = >20 mm / 0.79"
The main drain channel-pipe must have the capacity to be able to handle the total output of all connected
machines. In a drainpipe, a deodorized must be provided every twenty meter, figure 23., pos.1 to assure
the good working of the drain pipe. If the main drain pipe cannot be sufficiently deodorized, install a deodorizer
per machine. 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 figure 23., d1, d2, d3.
The recommended drain pipes diameter for machines with one drain valve are:
o d1 = 75 mm / 3" for one machine
o d2 = 100 mm / 4" for two machines
o d3 = 125 mm / 5" for three machines
The diameters of drain pipe for machines with two drain valves must have dimensions suitable for double
the value of water flow.
