SAFETY - continued GROUNDING INSTRUCTIONS This compressor should be grounded while in use to protect the operator 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. 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. 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 two- prong 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 undersized 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 lenght and name plate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. Tab.1 SECTION VALID FOR A MAX LENGHT OF 20 mt single-phase CV kW 220/230V 110/120V

The diameter of the extension cable of the 3-phase compressors must be in proportion to its length: see table (tab 2) Tab. 2 SECTION VALID FOR A MAX LENGHT OF 20 mt three-phase CV kW 220/230V 380/400V

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 near water or in any environment where electric shock is possible

SAVE THESE INSTRUCTION AND

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 (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 infiatable 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. USE INSTRUCTIONS – 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).GB

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 without a plug. Connect a plug, with screw-on grommet and securing collar (fig.13), to the cable, consulting the table below. HP kW Power supply volt/ph Plug model 2 – 3 – 4 1.5 – 2.2 – 3 220/380/3 230/400/3 16A 3 pole + ground

5.5 – 7.5 – 10 4 – 5.5 – 7.5 220/380/3

230/400/3 32A 3 pole + ground 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. 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 (thermal- breaker). STARTING 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. In the SILENT compressor, check if the air flows is in the direction illustrated in fig.21A. 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). Fit the plug in the power socket (fig. 12 - 13) 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. solenoid-valve indicator-light “D” and the motor (C) indicator-light (C) go on in that order, this means the machine is operating perfectly (fig. 18).

TANDEM COMPRESSORS WITH TIMED

CONTROL UNIT (fig. 17) Fit the plug in the power socket (fig. 13) 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 start the compressor. Pos. 1 pumping element n. 1 only is operating Pos. 2 pumping element n. 2 only is operating Pos. 3 both pumping elements are operating simultaneously, at staggered starting times. 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. 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. 18 - 19). IMPORTANT The electro-compressors must be connected to a power socket protected by a suitable differential switch (thermal-breaker). The motor of GM-TR compressors is equipped with an automatic thermal breaker located inside the winding – this stops the compressor when motor temperature reaches excessively high values. If the breaker is tripped, the compressors restarts automatically after 10 to 15 minutes. The motors of compressor models VX are supplied with a manually resetting automatic amperometric thermal-breaker, located outside the terminal board cover. When the breaker is tripped, wait for a few minutes and then reset the breaker manually (fig. 20). The motors of the AB series compressors are supplied with a manually resetting amperometric thermal-breaker, located on the terminal board cover. When the breaker is tripped, wait for a few minutes and then reset the breaker manually (fig. 20). The safety davice is automatic in three-phase and silent compressors. When the thermal-breaker is tripped, the pressure switch is released to “0” (OFF) position. Wait for a few minutes and return the pressure switch to “I” (ON) position (with the exception of models: AB 100/245-335 Three-phase - AB 150/ 245-335 Three-phase - AB 200/245-335 Three-phase). For compressors supplied with a control unit, the thermal-breaker is installed inside the control unit. When the thermal-breaker is tripped, observe the following procedure (fig. 22):

• Turn the switches on the control unit cover to position “0”, open the cover and press push-button 1 of the thermal-breaker. Close the cover of the control unit and restart the compressor, observing the operations described in the paragraph “Starting compressors with control unit”. The same instructions apply to compressors powered at 60 Hz. ADJUSTING OPERATING PRESSURE (fig. 23)

ou 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, operating pressure must be correctly adjusted. COMPRESSORS WITH

D STARTING Release the pressure reducer knob by pulling it up, adjust pressure to CONTROL UNIT (fig. 16) the required value by turning the knob clockwise to increase pressure Fit the plug in the power socket (fig. 13) and turn the pressure switch to and anti-clockwise to reduce it. When you have obtained optimum position “I” (ON) (fig. 17). Turn the master power switch “A” on the control pressure, lock the knob by pressing it downward (fig. 23). For pressure unit to position I – power On is signalled by white indicator-light “E” reducers equipped without a pressure gauge, the set pressure can be going on. Turn switch “B” to position 1 to start the compressor. If the seen on the graduated scale located on the reducer body.21

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 position “0”. – No pressure in the air tank. 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. 24). You are recommended to replace the filter element at least once if the compressor operates in a clean environment, but more frequently if in a dusty environment. In the “red-head” models (fig. 25) (TR200 – TR255), the suction filter is located internally under the conveying cover (read-head). Unscrew the three cover securing screws, remove the cover from the guard joint, remove the filter from its seat, and begin cleaning, blowing compressed air in opposite to normal flow direction. In the Silent model, the filtering element can be replaced by taking off the soundproofing cabinet and proceeding in the same way as for the AB models (fig.29A). 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. 26) under the tank. Take care if there is compressed air inside the cylinder, and water could flow out with considerable force. Recommended pressure: 1 – 2 bar max. Condensate of compressors that are oil lubricated must not be drained into the sewer or dispersed in the environment as it contains oil.

OIL CHANGES – TOPPING UP WITH OIL

The compressor is filled with synthetic oil “FIAC Oil Synthesis”. We recommend a full change of oil in the pumping element within the first 100 hours of duty. The soundproofing cabinet is to be taken off first in the Silent model (fig.29A). Unscrew the oil drain plug on the housing cover, allow all the oil to flow out, and re-screw the plug (fig. 27 - 28). Pour oil into the upper hole of the housing cover (fig. 29 - 30) until it reaches the level indicated on the stick (fig. 9) or indicator (fig. 11) Pour oil into the upper hole of the head (fig. 30) in belt assisted units designed for topping up in that area. For the GM203 series, take the cap off and pour in 85 grams of oil directly from the bottle (see fig. 30a). Once a week: check oil level of the pumping element (fig. 11) and see if it needs topping up. For operation at ambient temperature in the range -5°C to +40°C, use synthetic 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.

Air losses These can be caused by poor tightness of a union – check all unions, wetting them with soapy water. Compressor turns but does not load Coaxial compressors: (fig. 32) - this may be due to failure of the valves (C1 – C2) or of a seal (B1 – B2): replace the damaged part. Pulley drive compressors: (fig. 33) - this may be due to failure of the valves F1 and F2 or of a seal (D1 – D2): replace the damaged part. GM 203 compressors: This may be due to the breakage of the valves (C1 - C2) or of the gasket (B1). Replace the damaged part (fig. 16A). - 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. 14) - Are power cable extensions of adequate diameter or length? - Is the work environment too cold? (under 0°C) - For series VX/AB: was the thermal-breaker tripped? (fig. 20); in the silent series (fig. 21) - Is there oil in the housing to ensure lubrication? (fig. 11) - 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 operating 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, turn the pressure switch to position “0” (OFF). - Never aim the air jet at people or animals (fig. 34) - 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 tubes, as they can reach high temperatures. Do not touch these parts to avoid burns.(fig. 18 - 19) - Transport the compressor, lifting or pulling it with the appropriate grips or handles (fig. 4 - 6) - Keep children and animals well away from the machine operating area. - If using the compressor for painting: a) Do not work in closed environments or near to naked flames b) Make sure there is adequate exchange of air at the place of work c) Protect your nose and mouth with an appropriate 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.GB

- If the compressor is located on a shelf or on a top 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 to avoid injury to yourself or damaging the compressor. (fig. 36) - Do not use the compressor as a blunt object toward things or animals, to avoid serious damage. - When you have finished using the compressor, always remove the plug from the power socket.
