Risk of bursting. Use only recommended air handling parts
acceptable for pressures not less than 125 psi (8.6 bar).
REPLACEMENT PARTS
When servicing use only identical replacement parts. Repairs should
be conducted only by an authorized service centre.
SAFETY
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shocks. The compressor is equipped with a
three prong cord and three-prong grounding type plug to fit the proper
grounding plug socket. The green (or green and yellow) conductor in
the cord is the grounding wire. Never connect the green (or green and
yellow) wire to a live terminal.
EXTENSION CORD
Only use extension cords with three conductor cord that have three-
prong grounding type plugs and three-pole that accept the
compressor's plug. Replace or repair damaged cords socket. Make
sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current
your product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. Table 1 shows the
correct size to use depending on cord length and name plate ampere
rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

WARNING:
Avoid electrical shock hazard. Never use this compressor with a
damaged or frayed electrical cord or extension cord. Inspect all
electrical cords regularly. Never use in or near water or in any
environment where electric shocks are possible.

OPERATION AND MAINTENANCE
NOTE:
The information contained in this Instruction Manual is
designed to assist
maintenance of the compressor. Some illustrations in this
Instruction Manual may show details or attachments that
differ from those on your own compressor.
INSTALLATION
Remove the compressor from its packing, makes sure it is in perfect
condition, checking if it was damaged during transport, and carry out
the following operations. Fit the wheels on the tanks on which are not
already fitted, observing the instructions in fig.1. In case of inflatable
wheels, the maximum inflation pressure must be 1,6 bar (24 psi).
Position the compressor on a flat surface or with a maximum
permissible inclination of 10°, in a well aired place protected against
atmospheric agents and not in a place subject to explosion hazard. If

you in the safe operation and
the surface is inclined and smooth, check the compressor does not
move while in operation - if it does, secure the wheels with two
wedges. If the surface is a bracket or a shelf top, make sure it cannot
fall, securing it in a suitable way. To ensure good ventilation and
efficient cooling, the compressor's belt guard must be at least 100 cm
from any wall (fig. 2).
-
Take care to transport the compressor correctly, do not overturn it
or lift it with hooks or ropes
-
Replace the plastic plug on the guard cover (fig.3 - 4) with the oil
level stick (fig.5) or with the relevant breather plug (fig.6), supplied
with the instructions booklet. Check oil level, consulting the
reference marks on the stick (fig.5) or the oil level inspection
window (fig.7).
Single-phase compressors are supplied with an electrical cable and
a two-pole + earth plug. The compressor must be connected to a
grounded power socket
Three-phase compressors (L1+L2+L3+PE) must be installed by a
specialised technician. Three-phase compressors are supplied without
a plug. Connect a plug, with screw-on grommet and securing collar, to
the cable, consulting the table below.

NOTE: 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 (n. 2 pumping elements on
the same tank) are supplied with a timed control unit for staggered
starting of the two pumping elements.
Installation instructions:
– 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. 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.
Never use the ground socket 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).
Check that the mains power matches that indicated on the electrical
data-plate, the permissible tolerance range is +/-5%.
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.
Press the knob located on the upper section of the pressure switch to
"0" position. Fit the plug in the power socket and start the compressor,
turning the pressure switch knob into "I" position. 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). After connecting
the compressor to the power line, load it to maximum pressure and
check exactly how the machine is operating.
COMPRESSORS WITH Y / D STARTING
Fit the plug in the power socket and turn the pressure switch to
position "I" (ON). 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 perfectly.
