Installation 

 

Pressure relief valves are sized to protect the system. Never change the pressure setting or 
tamper with the valve. Only the valve manufacturer and their authorized representatives are 
allowed to make such changes. 

 

Pressure relief valves are used to protect system integrity in accordance with 
safety standards. Failure to provide properly sized valves will result in death or 
serious injury. 

Pressure  relief  valves  are  installed  prior  to  any  potential  blockage  point  such  as  shutoff 
valves,  heat  exchangers  and  discharge  silencers.  Ideally,  the  valve  should  be  threaded 
directly  into  the  pressure  point  it  is  sensing,  not  connected  with  tubing  or  pipe.  Always 
direct discharge from relief valves to a safe area away from personnel. 

4.4 FLUID LEVEL INSPECTION 

Inspect the fluid level when the compressor is in shut down mode. Fluid level is indicated 
on the reservoir sight glass (see figure 3-1). The maximum fluid level is at the top red-mark. 
Add fluid until the top red-mark is reached. 

4.5 ELECTRICAL 

Before  installation,  the  electrical  supply  should  be  checked  for  adequate  wire  size  and 
capacity.  User  must  comply  with  national  &  local  electrical  codes.  The  codes  specify  the 
surrounding  clearance  requirement  for  the  electrical  panel.  Wiring  work  should  be 
undertaken  only  by  a  qualified  electrician  in  compliance  with  OSHA,  national  or  local 
electrical  code.  GC  compressor  provides  wiring  diagrams  for  user  reference.  Refer  to  the 
electrical  control  schematic  in  the  parts  manual  for  wiring  diagrams.  Genuine  fused 
disconnect  switch  or  circuit  breaker  should  be  purchased  from  the  manufacturer.  Any 
unreasonable voltage imbalance (5%) between phases must be eliminated and low voltage 
problems  must  be  corrected  to  prevent  excessive  current  draw.  Air  compressors  must  be 
grounded in accordance with applicable codes, regulations and requirement.
