Compressors installed on the 500 lt tank, with capacity of HP7.5/ 55 kW and HP10/7.5 kW can be
supplied a star/triangle starting control unit, whereas the TANDEM (2 pumping elements on the
same tank) are supplied with a timed control unit for staggered starting of the two pumping
elements.
5.4 Installation instructions:
5.4.1 Secure the control unit box on a wall or on a fixed support, and provide it with
a power cable with plug, of a diameter in proportion to its length.
5.4.2 Any damage caused by incorrect connections of the power line to the mains,
automatically excludes warranty of electrical parts. To avoid connection errors, we advise
you to contact a specialised technician.
IMPORTANT:
Never use the ground (earth) wire instead of the neutral wire. The ground connection must be
made to meet safety standards(EN 60204). The plug of the power cable must not be used as a
switch, but must be fitted in a power socket controlled by a suitable differential switch (thermal-
breaker).
5.5 Starting.
5.5.1 Check that the mains power matches that indicated on the electrical data-plate
(fig.14) – the permissible tolerance range is +/-5%.
5.5.2 When first starting compressors operating on 3-phase voltage, check the rotation
direction of the cooling fan by comparing it with the direction of the arrow on the belt
guard or on the protective housing. In the SILENT compressor, check if the air flows is in
the direction illustrated in fig.21A.
5.2.3 Turn or press into position “0” (according to the type of pressure switch fitted on
the appliance) the knob located on the upper section (fig. 15).
5.2.4 Fit the plug in the power socket (fig. 12 - 13) and start the compressor, turning the
pressure switch knob into position “I”.
5.2.5 The compressor is fully automatic, and is controlled by the pressure switch which
stops it when tank pressure reaches maximum value and restarts it when it falls to
minimum value. The pressure difference between maximum and minimum values is
usually about 2 bar (29 psi).
E.G. The compressor stops when it reaches 8 bar (116 psi – maximum operating pressure) and
restarts automatically when the pressure inside the tank drops to 6 bar (87 psi). After connecting
the compressor to the power line, load it to maximum pressure and check exactly how the
machine is operating.
5.6 Compressor with D type starting control unit (fig. 16) .
5.3.1 Fit the plug in the power socket (fig. 13) and turn the pressure switch to position
“I” (ON) (fig. 17). Turn the master power switch “A” on the control unit to position I –
power On is signalled by white indicator-light “E” going on. Turn switch “B” to position 1
to start the compressor. If the solenoid-valve indicator-light “D” and the motor (C)
indicator-light (C) go on in that order, this means the machine is operating correctly (fig.
18).
