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

•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.
