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)
Water-proof Cover with 10 gauge Wire Leads
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 or 24 volt DC, therefore installation must be done
to a DC power source of 12 or 24 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.
WIRING
Connect the black wire (negative) of the compressor to any of the Pressure Switch’s terminals.
The remaining Pressure Switch terminal should be connected to ground; secure the end under any metal
body bolt or to the negative side of the vehicle’s battery. Be sure that the ground connection is rust and paint
free.
