INSTALLATION

Please read and follow the installation instructions carefully to avoid injury or damage to the 

compressor or your vehicle. Each of our air compressors and parts have been carefully produced 

and packaged.  Before you begin installation, please familiarize yourself with Installation Parts List 

(Fig. 1) of this manual. 

Guidelines for Selecting Mounting Location:

The selection of proper mounting location for your air compressor will help ensure a long and 

trouble free compressor service life. Please pay close attention to the following guidelines: 

1. Select a FLAT, UPRIGHT AND SECURE location where the compressor can be mounted.

2. To maximize air compressor performance, locate compressor as CLOSE TO THE BATTERY 

  as possible so that length of positive lead wire required is at a minimum.  

3. Choose mounting location that is as cool as possible and AWAY FROM HEAT SOURCES. 

  The cooler the ambient temperature the less chance the compressor will overheat. 

4. This compressor is moisture & splash resistant, but NOT WATER PROOF.  Do not mount  

  compressor in locations where the unit is likely to come in contact with water. 

5. Select compressor mounting location where air line can be routed from compressor air inlet 

  to remote inlet air filter.  Make sure Remote Inlet Air Filter is located in a dry location, away 

  from water splashes.  

6.  You will also want to select compressor’s mounting location where the leader hose bracket 

  can be mounted to secure the 1.5 ft. leader hose. 

7.  If it is necessary to mount the air compressor farther away from the battery, such as 

  inside your vehicle or in the bed of your pickup, use a minimum 16 AWG positive lead wire 

  for remote installation.

8. Do not mount compressor near areas where flammable liquids are stored.

9. Use thread sealant for proper fitting installation. Teflon tape is not recommended. 

  Properly sealed, recommended torque is 12 to 15 ft. lbs
