7.2 Lines and Pipelines 7.2
Connect the customer-supplied supply and drain lines according to the information in the
dimensioned drawing. Steam, condensate, compressed air and water must be equipped with stop
valves. Follow DIN 1988 when connecting the water. To avoid transmission of structure-borne noise,
you can connect the pipelines with a spacer of flexible metal tubing and insulate the pipe holders.
7.2.1 Steam
Install the wiring system and connections.
Operating pressure 4 - 5 bar (58 - 72.5 psi) saturated steam.
If the admission pressure is more than 5 bar (72.5 psi), build in a reducing valve with pressure gauge
and set it so that the highest permissible temperature for perc of 150 °C ( 302 °F) (measure!) is not
exceeded (danger of solvent decomposition and damage to the machine).
Peak steam demand (large steam generator):
Drying
0.5 kg/min (1.1 lb/min)
Distillation 0.8 kg/min (1.8 lb/min)
1 = reducing valve
2 = vacuum breaker
3 = descending slope
4 = steam trap
5 = stop valve
6 = non-return valve
7 = drain

7.2.2 Condensate
Install condensate line so that it slopes away from the machine, if possible. If there is an ascending
slope, provide a non-return valve and drain at the lowest point.
Attention:
Condensate counter-pressure must be at least 1.5 bar (21.8 psi) under the
incoming steam pressure.
