Safety Precautions

•Relieve  the  system  of  all  pressure  before  servic ing 

any part of the unit.

•Allow  ample  time  for  the  compressor  to  cool  before 

performing service procedures. Some surface 

temperatures exceed 350°F when the compres-

sor is operating.

•All  installation,  maintenance  and  repair  work 

must be performed by a qualified technician or 

electrician.

•Do  not  remove  or  paint  over  any  DANGER!, 

WARN ING!, CAUTION!, or instructional materi-

als at tached to the compressor.

•Periodically  check  all  pressure  relief  valves  for 

proper  op eration.

•Do  not  change  the  pressure  setting  of  the  pressure 

relief valve, re strict the function of the pressure 

relief valve, or replace the pressure relief valve 

with a plug.

•Do  not  install  a  shutoff  valve  in  the  compressor 

discharge line with out first installing a pres sure 

relief valve of proper size and design be tween the 

shutoff valve and the compressor.

•Do not make alterations to this compressor.
•Do  not  operate  the  compressor  in  excess  of  its  135

DESCRIPTION
& APPLICATION

Air Master Series single stage compressors are air-

cooled and  splash lubricated. It is the installers 

responsibility to meet the appropriate codes and 

regulations for this type of installation.

INSTALLATION

Air Master Series air compressors should be oper-

ated in a secure upright position and located in an 

area that is clean, dry, well lighted, and adequately 

ventilated. The compressor belt guard must not be 

located closer than 18 inches to a wall, or 24 inches to 

an other compressor. Additional safety can be achieved 

by locating the pulley drive system, with the guard, 

next to the wall. Do not allow hot air from additional 

equipment to blow towards the compressor.

It is recommended that the compressor be oper-

ated in temperatures under 104°F and over 32°F. In 

cold climates, the compressor should be in stalled in 

a heated building.

DANGER !

Under no circumstances should a compressor be 
used in an area where toxic, volatile, or corrosive 
agents are used or stored near the compressor.

Noise

Federal and local laws govern acceptable noise levels; 

should a question about noise levels arise, check with 

local officials for specifications.
