Page 5: General Information
Sight glass - Check Daily The compressor oil level can be viewed through the sight glass; the compressor must be on a level surface. The top of the red dot indicates the full mark the bottom of the red dot indicates the low mark. Always ensure that the oil level is correct before operating the compressor. - Page 6 Don’t Turn the Compressor on and off at the Wall Use the Pressure switch – On / Off The pressure switch automatically controls the power to the motor and operates the pressure relief valve. It also allows for manual operation via the Push/Pull - On/Off switch on top of the pressure switch.
- Page 7 Power supply / 3 phase, 50Hz It is essential that the air compressor has an adequate power supply. The air compressor should be operated on a dedicated 3 phase 415 volt circuit. The compressor must be connected to a properly grounded circuit of adequate capacity.
- Page 8 • Never allow children, pets or untrained personal to “play” with compressed air. • Keep children, pets or unauthorized personal away from the compressor at all times. • Compressed air can contain carbon monoxide, hydrocarbons and/or other poisonous contaminants that can cause death or serious injury.

Page 10: 2.2 Preparation Before Starting
2.2 Preparation before Starting RECEIPT AND INSPECTION Ensure that adequate lifting equipment is available for unloading and moving the air compressor to the installation site. Lifting equipment, slings, etc. must be properly rated for the weight of the compressor. Lift the compressor from the delivery vehicle by the shipping pallet only. Do not use the electric motor lifting eyebolt to lift the entire compressor. -
Page 11: Noise Considerations
Noise Considerations Check the State Workplace Health and Safety Regulations and/or Local Council regulations regarding acceptable noise levels. To reduce excessive noise, use vibration isolators, relocate the compressor or construct an enclosure or baffle walls. Discharge Piping All piping, fittings, air receiver tanks, and so on connected to the compressor discharge must be certified safe for the unit’s discharge pressure and temperature. - Page 12 ELECTRICAL CONNECTION This work must be carried out by a licensed electrician. All 3 phase compressor are not supplied with a power lead or plug. A licensed electrician is required to wire up the compressor from the wall mounted contactor box, to a dedicated 3 phase electrical outlet, either with a four pin plug or hard-wired into the electrical supply.

OPERATION Before operating the air compressor, always check first to ensure that it has been received, inspected and installed in accordance with the instructions herein. Rectify any discrepancies before proceeding further. Check the compressor pump oil level by looking at the sight glass. The oil level should be at the top of the red circle on the oil sight glass. - Page 14 Optional Accessories (not standard equipment) Air Dryer:- A compressed Air Dryer is a device for removing water vapor from compressed air. The process of compressing air concentrates water vapor from the atmosphere, which raises the dew point of the compressed air relative to free atmospheric air and leads to condensation within pipes as the compressed air cools downstream of the compressor.

Chapter 3 Maintenance of the air compressor WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO ELECTRICITY, HOT SURFACES, HIGH PRESSURE AIR, MOVING PARTS, OR FIRE WHICH MAY RESULT IN INJURY OR DEATH. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, DISCONNECT ANY POWER SOURCE; LET THE COMPRESSOR AND MOTOR COOL DOWN COMPLETELY. - Page 16 Check for any loose fasteners after 10 hours of operation • Check that all nuts and bolts are properly tight • Drain and replace the pump lubricant Replace pump oil with Scorpion compressor oil. (this will remove abrasive particles, from initial run in period) After 10Hrs of use Air filter maintenance Remove the outer cover to access the filter element...

Check belt tension Correct belt tension is important if the belt is too tight it will cause the motor to overheat and increase electricity consumption. If the belt is too loose it may slip easily, whip and break. The drive guard must first be removed before V-belt tension can be checked or adjusted, hang a weight of about 3kg at the mid point of the belt. -
Page 18: Troubleshooting
Air Tightness While the air receiver tank is pressurized to at least 120 psi and the compressor is switched off, listen for any audible air leaks. Squirt soapy water around any suspect joint and watch for bubbles indicating a leak. De-pressurize the air receiver tank carefully and all connected air hoses and/or air piping before commencing any repairs. - Page 19 Symptom Possible Cause Corrective Action Motor will not start, runs slowly or 1.
