Safety Precautions
Read this manual and follow all instructions prior to
installing or operating this compressor.
Listed below are some, but not all, safety precautions that
must be observed with compressors and compressed air
systems.
Failure to follow any of these warnings 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 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 shut-off 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.
• Use the correct fluid at all times.
• Do not rely on the discharge air line check valve.
• Do not override any safety or shutdown devices.
• Keep doors closed during operation. The noise level
inside cabinet exceeds 100 decibels (dBA) and the
operating temperature of some components is
sufficient to burn the skin.
