AIR CIRCUIT CONNECTION
Make certain that the compressed air hoses used have adequate maximum pressure
rating and section for the compressor. Never repair defective hoses; they must always
be replaced.
Connect the compressor to the pneumatic mains system, using the special female connection as
indicated in the overall dimensions section (chap.6)

FIRST START-UP
The first compressor start up (operational testing) must be performed by a qualified technician.
Remember, for the technical warranty to be valid, that the registered test report (R.C.R.) attached to
the documentation must be filled out (see notes on sales clauses).
After having followed all the indications contained in the previous chapters, it is possible to proceed
with the preparation of the machine for the first start-up.
For the three-phase version, is present in the compressor a control device which ensures the correct
rotation of the screw unit each time the compressor starts.
If the supply phases are correctly positioned the compressor will start as indicated on the arrow on
the body of the screw and as shown in Picture 10.
This control must be carried out making performing a start with an immediate
shutdown and checking that the electric motor fan turns in the same direction of the
arrow placed over the screw (three-phase version only).
If the phases of the supply line are positioned incorrectly, the compressor does not start.
Swap the connections of two phases of power line and restart the compressor.
