The Turbo Air® 3000 Centrifugal Compressor Compressor Handbook

Installation
CAUTION:
When fabricating the coolant supply piping (Figure A—11), always install the throttle
valve on the discharge side of the manifold rather than the inlet side. This will ensure that
the coolers are always flooded and that no air locks will form to restrict flow.
After fabrication of the cooling water piping is complete and before the initial compressor startup,
install temporary filter screens in the supply lines just before entry to the heat exchangers. Flush the
pipes thoroughly, and when it is determined that the supply piping is completely free of any foreign
matter, remove the screens. Reconnect the compressor manifold, and verify that there are no external
leaks. To verify that there are no internal leaks, open the condensate drains of the intercoolers and
aftercooler.
