    Instruction Manual Airmac Air Compressors Safety The air compressor set should only be operated by authorised persons. All users should follow the instructions and safety warnings as (a) described in this instruction manual, (b) shown on any decals affixed to the unit and (c) described in the Plant Risk Assessment that’s also available from the manufacturer.
  • Page 5 Instruction Manual Airmac Air Compressors Always refuel an engine-powered compressor outdoors in a well-ventilated area. Do not remove the fuel cap or refuel the compressor while the engine is running. Always turn engine off and allow it to cool down before refuelling.

  • Page 14: Application And Function

    Airmac Air Compressors Application and Function Your Airmac air compressor is an air cooled, reciprocating type. Depending on the model, it is fitted with either an oil lubricated or oil free compressor pump, which will feature either single-stage or two-stage compression. It is typically supplied as a compact, self-contained, air receiver tank mounted unit that is automatically regulated and driven by an electric motor or internal combustion engine through V-belts.
  • Page 15 Airmac air receiver tanks are designed and manufactured to comply with the requirements of Australian Standard AS 1210 and all Australian Workplace Health and Safety Regulations. A copy of the Manufacturer’s Data Report (as per AS 4458) is available from your Airmac dealer or Glenco Air & Power Pty Ltd upon request.

    Airmac dealer immediately. Do not operate unit if damaged during shipping, handling or use. Read the compressor model label to verify it is the correct one as ordered. For electric compressors, check the motor nameplate to verify that it is compatible with the available electricity supply.

  • Page 17: Installation

    Instruction Manual Airmac Air Compressors Installation Handling Remove the air compressor from its shipping carton and pallet before mounting. Do not use the timber shipping pallet for mounting the compressor. Portable wheel-mounted compressors should only be lifted manually as a last resort and always as a joint lift by at least two persons.

  • Page 20 Instruction Manual Airmac Air Compressors Figure 5-3 Preferred Bolted-Down, Foot-Mounting Arrangement – Option 1 (c) Another preferred method as shown in Figure 5-4 is for the compressor set to be mounted on correctly selected and installed industrial vibration isolators. Specialist providers include Mackay (www.mackayrubber.com.au) and Embelton (www.embelton.com).
  • Page 21 Instruction Manual Airmac Air Compressors Figure 5-5 Prohibited Bolted-Down, Foot-Mounting Arrangements Ambient Temperature The air compressor is designed for operation in ambient temperatures of between 0°C (32°F) and 40°C (104°F). Where possible in hot areas, the compressor should be operated in the shade to prevent additional heat load due to solar radiation.
