General Information

Safety Precautions

Read this manual and follow all instructions prior to installing or operating the compressor. Listed below are some, but not all, safety precautions that must be observed with compressors and compressed air systems

Warning!

Failure to follow any of these precautions may result in severe personal injury, death, property damage and/or compressor damage.

• Air from this compressor will cause severe injury or death if used for breathing or food processing. Air used for these processes must meet OSHA 29 CFR 1910.134 or FDA21XDE178.3570 regulations.
• • Disconnect and lockout all power supplies to the compressor plus any remote controllers prior to servicing the unit.
• • Never assume it is safe to work on the compressor because it is not operating. Many installations have automatic start/ stop controls and the compressor may start at any time.
• • This compressor is designed for use in the compression of normal atmospheric air only. No other gases, vapors or fumes should be exposed to the compressor intake, nor processed through the compressor.
• • Relieve all pressure internal to the compressor prior to servicing. Do not depend on check valves to hold system pressure. • A properly sized pressure relief valve must be installed in the discharge piping ahead (upstream) of any shutoff valve (block valve), heat exchanger, orifice or any potential blockage point. Failure to install a pressure relief valve could result in the rupturing or explosion of some compressor component.
• • Do not change the pressure setting of the pressure relief valve, restrict the function of the pressure relief valve, or replace the pressure relief valve with a plug. Over pressurization of system or compressor components can occur, resulting in death, severe personal injury or property damage.
• • Never use plastic pipe, rubber hose, or soldered joints in any part of the compressed air system. Failure to ensure system compatibility with compressor piping is dangerous.
• • Never use a flammable or toxic solvent for cleaning the air filter or any parts.
• • Do not remove any guards or cabinet panels or attempt to service any compressor part while the compressor is operating. • Do not operate the compressor at pressures in excess of its rating.
• • Observe control panel displays daily to ensure compressor is operating properly. • Follow all maintenance procedures and check all safety devices on schedule.
• • Never disconnect or tamper with the high air temperature (HAT) sensors. • Compressed air is dangerous, do not play with it.
