PLANNING YOUR INSTALLATION

• Before beginning the installation, determine each component’s spot.
• Confirm you have the proper length of airline and wire.
• Power wire to compressor should be kept short.
• To power up the air compressor, make sure you use a 12-gauge wire or thicker.

HORN
MOUNTING

• Identify a suitable area for mounting, preferably an unobstructed sheet-metal surface like the frame or body of the vehicle so as to provide a firm platform which will help protect the horn from damage due to excessive shaking. Do not attach the horn to any plastic or other flexible material.
• Using the bracket as a guide estimate and mark the positions for the holes and then perforate to size using a drill.
• Use the provided mounting hardware to fasten the horn.

CONTROL BOX MOUNTING

• Find a mounting location for the control box in which you will have access to the buttons and connector.
  IMPORTANT: Make sure that the control wire harness can reach the connector in the horn.

• Mount the unit on the location chosen using the small screws, washers and nuts provided.

AIR LINE INSTALLATION

• Using the provided 1/4″ OD air line, cut the size needed.

• Push hose into the push to connect cross fitting located in the top of the horn.

• Connect the other end of the air line to the compression fitting on your air supply. Place the compression nut of the air tank fitting on it. Force the air line onto the male fitting of the tank and then fasten the compression nut.
  WARNING: Avoid over tightening.

• If you need to disconnect the air line from the solenoid pull away the air line while pushing the plastic part of the pneumatic fitting.

COMPRESSOR MOUNTING

• Determine a dry place to mount your compressor. If you have chosen to install in the engine compartment, you should mount it as close to the front as possible to allow for maximum flow of air around compressor and also to avoid heat from the exhaust. IMPORTANT: Never attach the compressor to any plastic or other flexible material.
•  For optimal results, the compressor should be placed as close to the battery as possible. This will reduce the amount of wiring needed.
•  Avoid placing compressor near flammable liquids.
• If you are planning to move compressor’s air intake to an area other than where the compressor was installed, make sure your placement allows for the airline to be routed from the air inlet of the compressor to the remote inlet air filter (remote installation kit sold separately)
• Mark the spots for the holes with the mounting base as a guide and then drill. Make sure the compressor is secured.
• To enhance performance and make sure the battery of your vehicle doesn’t discharge, keep the engine running while the compressor is being used.

BRAIDED HOSE INSTALLATION

• Connect the stainless steel braided hose of the compressor to the tank’s inlet port.
• IMPORTANT: The tank’s inlet port must be 1/4″ N.P.T. (National Pipe Thread).

CHECK VALVE

• The check valve is an important part of the air compressor and has only one function: to let air flow from one side to the other, in this case from the compressor to the tank, while blocking air flow in the opposite direction.
•   IMPORTANT: When installing the braided hose do not rotate or remove the inline check valve located at the end of the hose on the side that connects to the air tank. Doing so will damage its seals and will result in damage to your air compressor.

REMOTE FILTER

• Using a compatible remote air filter installation kit (sold separately) your compressor’s air intake can be installed in an area other than where the compressor was installed.

THERMAL OVERLOAD PROTECTION

• The compressor has Thermal Overload Protection, if this protection activates, cut off the source of power and let the unit cool down for about 30 minutes. This will reset the system and allow you to safely resume use of the air compressor.

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 170 PSI ON, 200 PSI OFF. When the air pressure in the air tank is below the preset ON pressure (170 PSI), the compressor will automatically turn on and will start pumping air into the tank. When the pressure reaches the cut OFF pressure (200 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 250 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.

ELECTRICAL CONNECTION
COMPRESSOR

• The red wire of the compressor should be connected to (+) 12-volt power source. IMPORTANT: To prevent the compressor from over running and possible damage due to an air leak, connect the compressor’s red wire to a power source in the vehicle that only gets power when the vehicle’s ignition is on. Recommended connection points are: windshield wiper motor, blower motor or an accessory terminal on the fuse panel. Make sure to use wire that is as heavy as the wire of the compressor.

• Attach the black wire to any of the Pressure Switch’s connections located on the air tank.

• The remaining Pressure Switch connection should be attached to ground. Secure the end under any metal body or to the negative side of the vehicle’s battery. The ground connection should be rust and paint free.
  Your compressor is now set for use and will turn on automatically when air pressure in the air tank falls. When air pressure reaches maximum PSI, it will turn off. If the compressor fails to reach the maximum air pressure of the tank, which is the Pressure Switch’s cut OFF pressure, check all air connections for leaks. While the compressor is pumping, use soapy water or any bubble solution to perform this check. In case the leak remains after tightening, re-apply thread sealant.

• CAUTION: Never touch fittings, braided hose or the air compressor with bare hands either during or shortly after use.

HORN (SOLENOIDS)
USING NEW HORN BUTTON

• Locate the two wires in the air valves distribution block.
• Connect the RED wire to the positive (+) terminal of the battery, alternator, etc. This circuit should be protected using a 10A fuse (not provided).
• Connect the BLACK wire to one of the Horn Button’s connections. The remaining connection of the Horn Button must be connected to ground, this can be an unpainted metal on the chassis of your vehicle.
• Connect the wire harness to the 9-PIN connector located also in the air valves distribution block and then connect the other end to the control box.

USING VEHICLE’S HORN SWITCH

• First, determine the switch’s polarity. The horn of most vehicles sends a negative (-) signal which can be confirmed by connecting one of the probes from an ohm meter to the wire of the horn while connecting the other one to ground. The meter should be at zero. This proves that horn circuit is negative (-). In case the meter reads anything other than zero ohms, test for voltage between the wire of the horn and the ground. A 12-volt reading would mean a positive (+) horn circuit.
• Once you know the horn circuit’s polarity.
• If you have a negative horn circuit, connect the RED wire of the horn to a constant 12-volt power source, then connect the BLACK wire of the horn to the vehicle’s horn wire.
• If you have a positive horn circuit, connect the RED wire of the horn to the vehicle’s horn wire, then connect the BLACK wire of the horn to a constant 12-volt power source.

MAINTENANCE

• Make sure that electrical and fitting connections are regularly inspected, cleaned and tightened when needed.
• Make sure mounting screws are regularly tightened if needed.
•  Drain weekly, to avoid excessive buildup of condensation.
• Compressor features a washable air filter which should be cleaned using any mild form of liquid soap every two months if it gets dusty. Just remove the front cover of the filter’s housing to reach it. Replacement time frames depend on the operating environment and how often it is used.
• Clean dirt and dust from heat spreader and motor housing of the compressor.
• The motor of the air compressor has a maintenance-free lasting lubricant. DO NOT LUBRICATE.
