Note
After-coolers, separators, collecting reservoirs and
the compressed air lines must be equipped with drain
facilities at their lowest points to drain collected liquids.
These facilities have to be fitted to allow the observan-
ce of the draining of such liquids.
Hand-operated drain facilities have to be actuated in
accordance with the operating instructions.
Automatic drain facilities have to be checked for pro-
per function at regular intervals. When draining con-
densates into a collecting line, which also collects the
condensate from other machines, make sure that the
collecting line is free from counterpressure. Therefore,
measures have to be taken to ensure that counterpres-
sure cannot build up.
Condensate may contain oil ! When draining conden-
sate, observe the corresponding regulations for waste
water disposal.
The screw compressor is completely assembled in
the factory.
