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.

• 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.
