WARNINGS GROUNDING INSTRUCTIONS

• This compressor should be grounded while in use to protect the operator from electric shock. The single-phase compressor is equipped with a two-pole plus ground cable.
• Never disassemble the compressor or perform other connections in the pressure switch. Any repairs must only be performed by authorized service centers or other qualified centres. The green or green and yellow conductor in the cord is the grounding wire. Never connect the green wire to a live terminal. Before replacing the plug of the power cord, make sure you have connected the ground wire. Should you have any doubts, call a qualified electrician and check the ground connection.

EXTENSION CORD
Use only extension cords that have three-prong grounding type plugs. 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 lo carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The diameter of the extension cable must be in proportion to its length: see table (tab 1).

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 altachments that differ from those on your own compressor.

INSTALLATION

• Remove the compressor from ils 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 instructions 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 flal surface or with a maximum permissible inclination of 10° (fig. 3), in a well aired place, protected against almospheric agents and not in a place subject to explosion hazard. If the surface is inclined and smooth, check if the compressor moves white 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 (fig, 4)-

USE INSTRUCTIONS

• Take care to transport the compressor correctly, do not overlurn it or lift it with hooks or ropes (fig. 5 – 6)
• Replace the plastic plug on the housing, with the oil plug supplied and check oil level (fig.7)

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.8).
  NOTE: The equipment must be connected lo a maximum impedance of 0.37 Q.

STARTING

• Check that the mains power matches that indicated on the electrical data-plate (fig.9) the permissible tolerance range is +/-5%.
• Turn or press into position “0” (according to the type of pressure switch fitled on the appliance) the knob located on the upper section (fig.10). 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 lo minimum value. The pressure difference between maximum and minimum values is usually about 2 bar (29 psi). E.g.: lhe compressor stops when it reaches 8 bar (116 psi – maximum operating pressure) and restarts automatically when the pressure inside the tank drops lo 6 bar (87 psi), After connecting the compressor to the power line, load it to maximum pressure and check exactly how the machine is operaling.
• When the temperalure is <10 ° C it is recommended to make the first start with the tank unloaded (0 bar); il is recommended to depressurize the tank again, in case the compressor has stopped at low temperature within 30 minutes from the first start up.
  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 (fig.17),
  IMPORTANT
  The electro-compressors must be connected to a power socket protected by a suitable differential switch (thermal-breaker). The motor of compressors is equipped with an automatic thermal breaker located inside the winding – his slops the compressor when motor temperature reaches excessively high values. If the breaker is tripped, the compressors restarts automatically after 10 to 15 minutes, The same instruclions apply to compressors powered at 60 Hz.

ADJUSTING OPERATING PRESSURE (fig. 14)

You do not have to use the maximum operating pressure at all times. On the contrary, the pneumatic tool being used often requires less pressure. On compressors supplied with a pressure reducer, operaling pressure must be correctly adjusted, Release the pressure reducer knob by pulling it up, adjust pressure to the required value by turning the knob clockwise to increase pressure and anti-clockwise to reduce it. When you have obtained optimum pressure, lock the knob by pressing it downward. For pressure reducers equipped without a pressure gauge, the set pressure can be seen on the graduated scale located on the reducer body. On pressure reducers equipped with a pressure gauge, pressure can be seen on the gauge itself.
WARNING: Some pressure regulators do not have “push to lock” therefore simply turn the knob to adjust the pressure.

MAINTENANCE

• Before attempting any maintenance jobs on the compressor, make sure of the following:
  • Master power switch in position “0”.
  • Pressure switch and the control unit switches all off, in posilion “0”.
  • No pressure in the air lank.
• Every 50 hours of duty: we advise you to dismantle the suction filter and clean the filtering element by blowing compressed air on it (fig. 13). You are recommended to replace the filter element at least once if lhe compressor operates in a clean environment, but more frequently if in a dusty environment.
• The compressor generates condensate water which accumulates in the tank. The condensate in the tank must be drained at least once a week, by opening the drain tap (fig. 12) under the tank. Take care
• if there is compressed air inside the cylinder, and waler could flow out with considerable force. Recommended pressure: 1 ÷ 2 bar max. Condensate of compressors that are oil lubricated must not be drained inlo the sewer or dispersed in the environment as it contains oil.

OIL CHANGES – TOPPING UP WITH OIL

• The compressor is filled with oil “GSP High-Performance”. We recommend a full change of oil in the pumping element within the first 100 hours of duty.
• Unscrew the oil plug on the housing cover, allow all the oil to low out, and re-screw the plug. Pour oil into the upper hole of the housing cover until it reaches the correct level showed by oil level light (fig. 13).
• Once a week check oil level of the pumping element and see if it needs topping up.
• For operation at ambient temperalure in the range -5°C to +40°C, use synthelic oil. The advantage of this oil is that is does not lose its characteristics either in winter or summer. Do not drain used oil into the sewer or dispose of it in the environment.

OBSERVE THIS TABLE FOR OIL CHANGES

WHAT TO DO IF SMALL MALFUNCTIONS OCCUR

• Loss of air in valve under pressure switch
  This trouble depends on poor tightness of the check valve – take the following action (fig. 16):

  • Discharge all pressure from the tank
  • Unscrew the hexagon-head of the valve (A)
  • Carefully clean both the rubber disk (B) and its seat
  • Refit all parts accurately.

• Air losses
  These can be caused by poor lightness of a union – check all unions, wetting them with soapy water.

• Compressor turns but does not load

  • This may be due to failure of the valves or of a seal (fig. 15): replace the damaged part
  • Check if there is too much condensate water inside the tank.

• Compressor no starting
  If the compressor has trouble starting, check the following :

  • Does mains power match that of the data-plate? (fig, 9)
  • Are power cable extensions of adequate diameter or length?
  • Is the work environment too cold? (under 0°C)
  • Is there oil in the housing lo ensure lubrication?
  • Is power supplied to the electrical line (sockets well connected, thermal- breaker, fuses in good condition).

• Compressor not stopping
  If the compressor does not stop when maximum pressure is reached, the tank safety valve comes into operation, To repair the valve, contact your nearest service centre.
  IMPORTANT

  • Do not on any account unscrew any connection while the tank is pressurised always check if the tank is pressure free.

  • Do not drill holes, weld or purposely deform the compressed air tank.

  • Do not do any jobs on the compressor unless you have disconnected the power plug

  • Temperature in operaling ambient: 0°C +35°C.

  • Do not aim jets of water or inflammable liquids on the compressor.

  • Do not place inflammable objects near the compressor

  • During down-times, lurn the pressure switch to position “0” (OFF).

  • Never aim the airjet at people or animala.

  • Do not transport the compressor while the tank is pressurised.

  • Be careful with regard to some parts of the compressor such as the head and delivery lubes, as they can reach high temperatures. Do not touch these parts to avoid burns. (fig. 17)

  • Transport the compressor, lifting or pulling il with the appropriate grips or handles

  • Keep children and animals well away from the machine operaling area.

  • If using the compressor for painting:

  • Do not work in closed environments or near to naked flames;

  • Make sure there is adequate exchange of air at the place of work;

  • Protect your nose and mouth with an appropriale mask. (fig. 35)

  • If the electrical cable or plug are damaged, do not use the compressor and contact an authorised service centre to replace the faulty element with an original spare part.

  • If the compressor is located on a shelf or on a lop above floor height, it must be secured to prevent it falling while in operation.

  • Do not put objects or your hands inside the protective grilles lo avoid injury to yourself or damaging the compressor.

  • Do not use the compressor as a blunt object loward things or animals, to avoid serious damage.

  • When you have finished using the compressor, always remove the plug from the power socket.
    NOTE: For the European market, the compressor tanks are manufactured to meet Directive CE2009/105. For the European market, the compressors are manufactured to meet Directive CE2006/42.

1. use the vessel properly, within the pressure and temperature limits stated on the nameplate and on the testing report, which must be kept with care;
2. welding on the vessel is forbidden;
3. assure that the vessel is complete with suitable and adequate safety and control fittings and replace them with equivalent ones in case of necessity. In particular, the safety valve must be correctly applied directly to the container with no possibility of interposition; it must also feature a discharge capacity greater than the amount of air that can be introduced into the container, it must be calibraled and sealed to the maximum allowable pressure indicated on the raling plate;
4. fit the pressure vessel with vibration damping supports in order to avoid risk of the vessel being subject to detrimental vibrations during operation which could lead to fatigue failure.
5. Corrosion must be prevented: depending on the conditions of use, condensation may accumulate inside the tank, and this must be emptied out every day. This may be done manually, by opening the draining tap, or by means of the automalic condensalion drainer, if fitled to the tank. During maintenance, periodically, the user or a Client Service expert must check the presence of internal corrosion and perform an external visual control. If the receiver is used with an Oilless compressor, or in surroundings that have a high level of humidity, or in adverse conditions (poor ventilation, corrosive agents,
6. the inspections should be made more frequently. The legal checks have to be made in accordance with the local laws and rules where the receiver is used.
7. Proceed sensibly and carefully, according to the existing prescriptions.

TAMPERING AND IMPROPER USE OF THE VESSEL ARE FORBIDDEN.
The users must comply with the laws on the operation of pressure equipment in force in the relalive countries
