To avoid overheating of the electric motor, this compressor is designed for intermittent operation as indicated on the
technical dataplate (for example, S3-25 means 2.5 minutes ON, 7.5 minutes OFF).

OPERATION AND MAINTENANCE
NOTE:
The information contained in this Instruction Manual is designed to assist you in the safe operation and
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 and rubber tab on the tanks on which they are not already fitted, observing the instructions in (fig.1a &
1b). Also fit the Air Filter (Fig 2). 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 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 must be at least 100 cm from any wall. 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. Verify that the tanks have been drained and are clear of any moisture or dirt.
INSTRUCTIONS FOR USE
-Take care to transport the compressor correctly, do not overturn it or lift it with hooks or ropes. Check oil level,
consulting the reference marks on the stick (fig. 3).
Oil lubricated compressors may come with a bottle of oil to fill or top up the compressors - note that not all oil supplied
may be needed to fill the unit to the correct level.
NOTE: Some units (MRC6, RC-10) are equipped with an oil-free pump. There is no oil to replace or check.
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.4).
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).
STARTING
Check that the mains power matches that indicated on the electrical data-plate (fig.5) - the permissible tolerance range
is +/-5%. 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. 6A, 6B, 6C). Fit the plug in the power socket and start the compressor, turning the
pressure switch knob into position “I”.
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.
NOTE:
The head/cylinder/delivery tube unit can reach high temperatures. Take care when working near these parts,
and do not touch them to avoid possible burns.
IMPORTANT
The electro-compressors must be connected to a power socket protected by a suitable differential switch
(thermal-breaker). The motor is equipped with an automatic thermal breaker located inside the winding - this stops
the compressor when motor temperature reaches excessively high values (180
o
C). If the breaker is tripped, the
compressors restart automatically after 10 to 15 minutes.
