SOME TIPS FOR TRAIN HORN/AIR HORN COMPRESSOR MOUNTING AND USE
Never mount an unsealed compressor outside of the vehicle. If water, dirt or debris is allowed to enter the intake, it will damage your compressor. Ensure you have a sealed air system before externally mounting.
Do not mount your compressor below the tank. The tank and/or the leader hose can create condensation, that will then leak into the compressor below. You do not want moisture entering your compressor.
Do not mount a compressor upside-down. Any other angle is acceptable, but mounting upside-down will not allow the compressor to cool properly and could burn it up.
Do not over tighten the leader hose. This can cause your check valve to malfunction, in which case, the compressor will not fill the air tank properly.
If your compressor is not filling your air tank… you may need to loosen the check valve.
Use the pressure switch that came with your kit to be safe. Pressure switches can vary in pressure rating. Not using a pressure switch at all is not advised.
Know your compressor’s maximum working pressure. Do not run your compressor beyond this pressure limit, doing so increases your risk of damage greatly.
Know your duty cycle. Every compressor has a duty cycle, indicating how long it can run before it needs to stop and cool down. If you run it too long, or don’t allow enough cool down time, it will over heat and burn up. Know the duty cycle and only run your compressor within it’s limits to avoid damage.
If your compressor won’t stop running, or runs longer than it should… there is most likely a problem with your pressure switch, for example, it could be leaking. You should disconnect power from the system until you have determined and fixed the problem to prevent damage.
