Risk of bursting. Use only recommended air handling parts accept-
able 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 authorized service center.
SAFETY - continued
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the op-
erator from electric shock. The compressor is equipped with a three-
conductor cord and three-prong grounding type plug to fit the proper
grounding type receptacle. All electrical repairs must be done by a
qualified electrician.
The green (or green and yellow) conductor in the cord is the ground-
ing wire. Never connect the green (or green and yellow) wire to a live
terminal. If your units is for use on less than 150 volts, it has a plug
that looks like that shown in sketch (A) in figure on the right. An
adapter, see sketches (B) and (C), is available for connecting sketch
(A) type plugs to twoprong receptacles. The green-colored rigid ear,
lug, or the like extending from the adapter must be connected to a
permanent ground, such as a properly grounded outlet box.
NOTE: the grounding adaptor, sketch (C), is prohibited in Canada by
Canadian Electrical Code Part.1. Therefore, the instructions for its
use are not applicable in Canada.
EXTENSION CORD
Use only three-extension cords that have three-prong grounding type
plugs and three-pole receptables that accept the compressor's plug.
Replace or repair damaged cord. 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 under-
sized cord will cause a drop in line voltage resulting in loss of power
and overheating.
Table 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 elec-
trical cords regularly. Never use in near water or in any environment
where electric shock is possible

OPERATION AND MAINTENANCE
NOTE: The information contained in this Instruction Manual is de-
signed to assist you in the safe operation and maintenance of the
compressor.
Some illustrations in this Instruction Manual may show details or at-
tachments that differ from those on your own compressor.
Remove the compressor from its packing (fig.1), makes sure it is in
perfect condition, checking if it was damaged during transport, and
carry out the following operations. Fit the wheels and rubber tab on
the tanks on which they are not already fitted, observing the instruc-
tions in fig.2.
In case of inflatable wheels, the maximum inflation pressure must be
of 1,6 bar (24 psi). Position the compressor on a flat surface or with a
maximum permissible inclination of 10° (fig. 3), in a well aired place,
protected against atmospheric agents and not in a place subject to
explosion hazard. If the surface is inclined and smooth, check if the
compressor moves 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. 4). Compressors fitted on the tank, with
fixed feet, should not be rigidly secured to the ground. In this case,
we advise you to fit 4 anti-vibration supports.
– Take care to transport the compressor correctly, do not overturn it
or lift it with hooks or ropes (fig. 5 - 6)
– Replace the plastic plug on the guard cover (fig. 7 - 8) with the oil
level stick (fig. 9) or with the relevant breather plug (fig. 10), supplied
with the instructions booklet. Check oil level, consulting the reference
marks on the stick (fig. 9) or the oil level inspection window (fig. 11).
ELECTRICAL CONNECTION
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 (fig.12).
Three-phase compressors (L1+L2+L3+PE) must be installed by a
specialised technician. Three-phase compressors are supplied with-
out a plug. Connect a plug, with screw-on grommet and securing col-
lar (fig.13), 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 start-
ing control unit.
Installation instructions:
– Secure the control unit box on a wall or on a fixed support, and pro-
vide 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 tech-
nician.
IMPORTANT:
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
(thermalbreaker).
Check that the mains power matches that indicated on the electrical
data-plate (fig.14) – 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.
Turn or press into position "0" (according to the type of pressure
switch fitted on the appliance) the knob located on the upper section
