Risk of damage to the machine!
If the inlet gas contains foreign solid particles:
• Install a suitable inlet screen (smaller than 0.4 mm mesh size) upstream of the ma-
chine.
Connection size(s):
– DN250 PN10 (for LG 0890 A and LR 0700 A)
– DN300 PN10 (for LG 1200 A and LR 1190 A)
– DN350 PN10 (for LG 1910 A and LR 1560 A)
– DN400 PN10 (for LG 2680 A and LR 2200 A)
5.2.2 Discharge Connection
NOTICE
Too high elevation or lack of separation.
Will cause back pressure and possible drive motor overload!
• The discharge piping on machines without integral separator manifold should not ex-
ceed an elevation of more than 1000 mm above the discharge flange (OUT) of the
machine until the liquid is separated.
Connection size(s):
– DN250 PN10 (for LG 0890 A and LR 0700 A)
– DN300 PN10 (for LG 1200 A and LR 1190 A)
– DN350 PN10 (for LG 1910 A and LR 1560 A)
– DN400 PN10 (for LG 2680 A and LR 2200 A)
• Make sure that the discharged gas will flow without obstruction. Do not shut off or
throttle the discharge line or use it as a pressurised air source.
