Preparing For the Install
Recommended Install Locations for Your Car (Compressor)
Recommended Install Locations for the Horns
•The trunk of your car/sedan/suv is a great spot for this air source kit. The trunk keeps the compressor
out of the weather and is one of the best install locations for the compressor/tank.
•The engine bay can also be used as an install location for the air source. If you have enough room to
mount the air source without getting too close to the engine, this will work just fine. Do not mount the
compressor to close to engine. If the compressor gets too hot, it will not run.
•If you decide to mount the compressor outside the car make sure it won't get submerged if you go
through a large puddle! It can get wet but you cannot submerge the system.
Check out the install photos below, these are two examples of installs in the rear storage area of a car.
•These horns will sound their best when facing down towards the ground, or towards the front of the vehicle
(these can face forward!) We typically see these mounted behind the front bumper, ahead of the radiator on
most vehicles. (see picture below, to the right)
oIf you opt to install the horns in the front grille, make sure that the opening at the end of each bell is not
blocked or covered. Make sure to leave some room for airflow to your radiator!

Preparing For the Install (continued)
Recommended Install Locations for Trucks (Compressor)
Recommended Install Locations (Horns)
•The toolbox is a great location for the compressor. Do not use the toolbox as a ground point as it will not be
directly connected to the frame of the vehicle.
•Mounting the compressor/tank underneath the bed is a great option. There's plenty of room available and
mounting the compressor outside will help it run cooler and save space in your bed / toolbox.
•The engine bay is a good spot for the compressor as long as you keep it away from the exhaust manifold and
engine block. The engine generates a lot of heat and will keep the compressor from running cool. If the
compressor overheats, it will not run until it has cooled off.
*Keep in mind that the air tank has to be close to the compressor. The leader hose on the compressor is 18"
long.
•You can mount these horns in the front bumper similar to a car or underneath the bed as shown above.
•If you face the horns forward when mounted underneath they may pickup some dirt/dust from the road. This
is normal and will not damage the horn. We suggest using a blowgun to remove excess dirt/dust from each
bell semi-annually.

Barb Fittings
(Male & Female)
Filter Housing
Relocation Air Line
www.hornblasters.com [email protected]
Start by locating the hardware that was packaged with your air compressor. You should have a set of
mounting bolts, two barb fittings, and an air filter housing. A picture of each is shown to the left for reference.
Let’s start by taking the fitting on the left with the male thread and inserting it into the
compressor inlet. The other fitting (female end) can be threaded onto the filter
housing directly. Your compressor/filter should look like the image below. At this
point, you can use the supplied air line that was packaged with the compressor to
connect the compressor and filter together.
**This line is not meant to hold pressure. Do not use this for anything other tha
the filter.

Filter Placement
Your compressor is fully sealed against the elements. If the compressor is mounted outside with the air filter
on the end of the compressor, the filter will get wet and water will get pulled into the compressor. To prevent
this, the filter must be relocated to an ENCLOSED AND DRY location. If your compressor is mounted in the
bed of your truck or underneath the bed, the filter could be relocated into the cab of the vehicle. The filter must
be relocated to an area where it will not be exposed to debris or moisture.
If the air filter is not relocated, the compressor will pull in water/dirt and will stop working properly. 9
out of 10 compressors that fail within the first year have pulled in water/debris from the intake.

Option 2
**Always make sure the drain cock is facin
DOWN. Regardless of how you decide to
assemble the tank, the drain fitting needs to
point down to allow water to drain. Gravity
will pull water to the bottom of the tank.

Plumbing the Compressor Into the Tank

Once you have assembled and mounted both the tank & compressor, plumb the compressor into the tank.
The compressors braided hose will thread into the reducer bushing that we plumbed into the end-cap of the tank,
(on the right hand side of the tank in the photos on page 8).
The photo to the right shows the check valve plumbed into the reducer bushing.
It is extremely important that you do not over-tighten this piece. Over-tightening this piece can lead to the
compressor not filling the tank.
Use a small amount (2-3 wraps) of teflon on this fitting. If teflon won't seal well, we recommend Loctite 545.
The check valve needs to be torqued to 12-14 ft lbs.
Screw this piece in hand-tight and give it another 1/4" turn
with a wrench.
Now that the compressor's plumbed into the tank, let's get the horns connected. Locate the roll of 1/2" air
line that was supplied with your kit. Make sure both ends are cut straight/flush. If one
end is not cut straight, the line will not make a proper seal in the fitting. Once the line is
cut, go ahead and push the line into the fitting on the end of the tank. The line will
simply push into the fitting and lock into place.
Be careful not to bend the airline right out of the fitting. This can
cause the fitting to leak over time. Take a larger bend further away
from the fitting to prevent the line from stretching the fitting out.
These fittings can be re-used with the same line multiple times. If
you need to remove the line, follow these steps:

Plumbing the Horns to the Valve
Locate the roll of 5/16" air line that was packaged with your kit. This line will be used to connect each horn bell to
the 4-way splitter on the solenoid valve. You will also need the 4x shocker elbow fittings that came with your kit.
Plumb each elbow fitting onto the brass stud of each horn as shown to the left. Do not use
Teflon tape here! Little pieces of the tape will find it's way into the horn and prevent it from
honking. Get each fitting hand tight and give them another 1/8" turn with a wrench if possible.
Be careful not to use too much force or the stud will break loose. These fittings DO NOT need
to be torqued down that much. They are not under constant pressure.
Make sure that:
•Both 5/16" lines are equal length
•Make sure each horn is mounted
properly before you drive the
vehicle.
•Ensure each line is properly
connected into each elbow fitting
and each side of the splitter.
Cut the roll of 5/16" line in half to make two separate lines. Each line must be the same length
so that each bell sounds off at the same time! At this point, connect each length of line from
the 4-way splitter into each elbow fitting on the horns. Make sure every connection is tight and
inserted all the way into each fitting.
Page 10
Locate the solenoid valve for your horns. Take note of
the arrow on the bottom of the valve (look at the
bracket reflection). This arrow must point TOWARDS
your horns. If the valve is mounted with the arrow
pointing towards the tank, the valve will not hold air
pressure and leak instantly.
Locate the 2-way splitter that came with your kit. Plumb this
fitting into the outlet side of the air valve. Use a wrench to
tighten the fitting snug. Be careful not to apply pressure to
the plastic portion of the fitting. It can/will break.
Grab the 1/2" line that we plumbed into the tank and route it
up to this valve. Insert the line into the 1/2" fitting on the inlet
portion of the valve.
