BEFORE INSTALLING THE COMPRESSOR OR PERFORMING  

ANY MAINTENANCE READ THIS MANUAL CAREFULLY. 

WARNINGS

COMPRESSED AIR AND ELECTRICITY ARE DANGEROUS. BEFORE DOING ANY WORK ON THIS UNIT, BE SURE THE
ELECTRICAL SUPPLY HAS BEEN SHUT OFF(LOCKED AND TAGGED) AND THE ENTIRE COMPRESSOR SYSTEM HAS
BEEN VENTED OF ALL PRESSURE. 
1.

Do not remove the cover, loosen or remove any fittings, connections or devices when this unit is operating or 
in operation. Hot liquid and air that are contained within this unit under pressure can cause severe injury or 
death. 

2.  The compressor has high and dangerous voltage in the motor, the starter and control box. All installations 

must  be in accordance with recognized electrical procedure. Before working on the electrical system, ensure 
that the  system's power has been shut off by use of a manual disconnect switch. A circuit breaker or fuse 
switch must be  provided in the electrical supply line to be connected to the compressor. The preparation work
for installation of  this unit must be  done on suitable ground, maintenance clearance and lightning arrestors 
for all electrical  components. 

3.  Do not operate the compressor at a higher discharge pressure than those specified on the compressor 

nameplate. If so an overload will occur. This condition will result in electric motor compressor shutdown. 

4.  Use only safety solvent for cleaning the compressor and auxiliary equipment. 
5.  Install a manual shut off valve(isolation type) in the discharge line for service work. 
6.  Whenever pressure is released through the safety valve during operation, it is due to excessive pressure in the 

system. The cause of excessive pressure should be checked and immediately corrected. 

7.  Before doing any mechanical work on the compressor, 

a)

Shut down the unit. 

b)  Electrically isolate the compressor by use of the manual disconnect switch in the power line to the unit. 

Lock and tag the switch so that it cannot be operated. 

c)  Release all compressed air within the system and isolate the unit from any other sources of air. 

8.  Allowing the unit lubricants to enter into the plant air system must be avoided at all times. Air line separators, 

which are properly selected and installed, can reduce any liquid carry-over  close to zero. 

9.  Before starting the compressor, the maintenance instructions should be thoroughly read and understood. 
10.  After maintenance work is completed, covers must be securely closed. 
11.  For questions contact your distributor before proceeding.
