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 taken all compressor assembly steps illustrated in
chapter 5
, prepare the machine for
first start-up.
Every time the compressor is turned on, the control panel runs a check on the power supply line
phases to ensure that the screw assembly is turning in the right direction.
If the power supply line phases have been correctly positioned, the screw will turn as indicated by
the arrow in
figure 9
.
If the power supply line phases are not positioned correctly, the machine blocked alarm will
appear on the panel.
In this case, switch connection of the two power supply phases on the line and start up the
compressor again.
Figure 9
WARNING!
Reverse screw rotation - turning opposite the direction indicated by the arrow in
relief on the body of the machine (see figure 9) - can damage the screw assembly!
WARNING!
If the electric motor is replaced, when it is started up once more, always visually
inspect the assembly to ensure that the screw is turning in the right direction.
WARNING!
Always carefully follow the SAFETY WARNINGS regarding use of the machine.
This is extremely important.
