AIR TANK
MOUNTING
Find a convenient mounting location in your vehicle for the air tank. Ensure ports are reachable before drilling
any holes.
Mark the location of holes using the mounting brackets of the air tank as a template, and then drill to size.
Using mounting hardware provided, secure the air tank.
IMPORTANT
: Do not mount on a flexible material.
The installation location of your tank’s accessories depends on your air system’s configuration.
PORT LOCATIONS AND THREAD SIZE (NPT)
PRESSURE SWITCH RATING
The included 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.
AIR PRESSURE GAUGE
In one of the Air Tank’s 1/4" NPT ports, using the thread sealant provided, install the air pressure gauge.
The side or top of the tank is the best location to use as to prevent condensation from entering into the gauge.
Dropping or disturbing the product can affect the product’s accuracy.
For best results, the air gauge should be installed perpendicular to the ground, with the zero facing the
bottom.
To tighten the pressure gauge into the air tank, place a wrench over the square wrench flats to tum the
gauge. This is the proper way to avoid air leakage or damage.
SAFETY VALVE
Your system comes with a safety valve designed specifically to release pressure from the air tank
automatically if 175 PSI is exceeded. This will help prevent an accident in case of pressure switch failure.
DRAIN VALVE
This valve helps you drain the water that can collect in the air tank after long periods of use.
REMOVING CONDENSATION
:
To
remove any condensation which has accumulated inside the tank, bleed the tank’s pressure until it ranges
from approximately 5 PSI to 20 PSI.
Remove the drain valve found at the tank’s bottom to drain the water from the tank. After draining the
accumulated condensation, reinstall the drain valve.
IMPORTANT
: Draining the system regularly will extend the life of the air tank.
THREAD SEALANT
Your system includes Premium Thread Sealant, make sure to use it on all thread connections to ensure
proper air sealing.
