START-UP AND OPERATION
1 - CHECKS TO BE CARRIED OUT PRIOR TO START-UP
N.B.: The customer is responsible for installing the machine and making the required electrical and air connections.
Initial system start-up must be carried out by skilled personnel who will make the various checks required and follow
the respective instructions.
Each machine was thoroughly tested at the plant before shipping.
You should monitor the compressor during the first hours of operations to check for faults.
• Follow the installation prescriptions given in the previous chapters.
• Remove all packaging materials and tools.
• Connect the compressor to the distribution line as shown in paragraphs.
• Check the oil level in the tank: refer to section “Maintenance, oil control and topping up.” In the event of low oil level, top up
with FSN Original Oil.
• Check for correspondence between the compressor plate data with the actual specifications of the electrical system.
A variation of ± 5% with respect to the rated value is allowed.
• Connect the machine to the electrical system as described in the previous chapters.
Compliance with the correct voltage phase sequence is
fundamental since this defines the direction of rotation of
the motor. The direction of rotation must be that indicated
by the adhesive label located to the side of the screw unit
(figure indicated to the side).
Note that even a few seconds of incorrect rotation may
cause serious damage.
A phase sequence checking device to prevent mistakes is
fitted in the electrical panel.
Now the machine is ready to go.
Before starting the machine read the following sections
and the chapter on maintenance operations for in-depth
knowledge of the machine.
