BEFORE BEGINNING YOUR INSTALLATION
Read through the instruction guide before getting started with the installation. Professional installation is recommended for
this product.
CONTENTS
120-150 PSI Pressure Switch (1/4" NPT)
SAFETY INSTRUCTIONS
Make sure your battery ground is detached before getting your installation started.
Employ equipment for eye protection during drilling operations.
Ensure that your air system has no pressure before starting the installation.
The specific voltage requirement for this pressure switch is 12 volt DC, therefore installation must be done to a
DC power source of 12 volts.
PRESSURE RATING
Pressure Switch has a rating of 120 PSI ON, 150 PSI OFF. When the air pressure in the air tank is below the
preset ON pressure (120 PSI), the compressor will automatically turn on and will start pumping air into the
tank. When the pressure reaches the cut OFF pressure (150 PSI), the compressor will be automatically shut
off.
MOUNTING
Apply thread sealant to pressure switch's threads and install it on one 1/4" NPT port available in the Air Tank.
DO NOT OVER TIGHTEN.
Inspect the connection for leaks with a mixture of soap and water.
IMPORTANT: For better performance, never install the pressure switch in a port facing the intake port of the
air tank. Best options are a port that is on the same side or perpendicular to the intake port.
