Section 5 - Lubrication 

-  This  compressor  is  designed  for  non-lubricated  service.  Bearings  are  permanently 
lubricated. 

Do not lubricate any part of the compressor or motor

 

 

Section 6 - Piping 

6.1 Piping Instructions 

-  Compressed  air

 

contains  liquid  water  and  is  saturated  with  water  vapor,  which  can 

freeze when surrounding temperatures are lower than 32°F (0°C). Component selection 
to minimize the effects of water vapor must be considered. 

 

Piping between the compressor, accessory items and the sprinkler system must be at least ½” internal diameter to minimize 
pressure  drop  from  the  compressor  to system.  Larger  pipe  size  may  be  required  by  code  and  may  be  substituted  with  no 
adverse effects. 

-  Smaller  line  size  must  not  be  used  and  will  restrict  the  compressor  flow,  lowering 
capacity  and  causing  the  compressor/motor  to  work  harder,  which  shortens 
compressor/motor  life. All  piping  connected  to the  compressor  must  be  fully  supported 
and not transfer any loads to the compressor.

 

 

 
If an air maintenance device (AMD) is used, allow sufficient distance between the compressor and AMD to ensure that the 
maximum temperature at the AMD is 200°F or less. 

 

- An AMD must be used with all riser mounted tank units. 

 

All oilless compressors include a relief valve which is installed on the compressor. This valve will open at a preset value above 
the pressure switch setting to prevent excess pressure in the event of a switch failure. 

 

- Do not attempt to change the safety relief valve setting. 

 

A manual drain is provided on the bottom of each riser mount model with a tank. Moisture accumulated in the tank must be 
drained weekly. 

The compressor outlet piping should contain an accessible drain. As a minimum a manual drain may be used, but an automatic 
drain is recommended to remove excess water. 

 

-  Accumulation  of condensed  water  in  the  system  can  cause  corrosion  of components 
and reduction of system capacity. 

- Warranty is void if a separate check valve is not installed to prevent water backflow to 
compressor. 

 

Optional Flex Hose Installation Instructions: 

An optional 30 inch Stainless Steel flex hose is available to aid the air compressor 
installation. Part number 6872000000 should be ordered if desired. The flex hose 
has ½” NPT male threads on both ends. Attach the flex hose to the air compressor 
discharge or the air tank first. Then install a union to connect it to the piping system.
