Preserving Your Horn Kit

After a correct install, maintenance is simple — but skipping it can shorten kit life or kill the system.

  • What you need: access to the tank drain cock and a replacement compressor air filter every few months

Preserving Power

If you have installed your system according to instructions, all of the hard work is done. Kits are designed to be as worry-free as possible — there isn’t a ton of maintenance when the install is done right. Skipping it, though, can significantly decrease lifespan or leave the system inoperable.

Basic Maintenance

1

Drain the air tank regularly

The number one enemy of any electrical component is water. Even with a perfect install, moisture from the air still enters the system and collects at the bottom of the tank. As it builds up, it can spread into electrical components and corrode the tank. Drain at least once a month — more often in humid climates.

Loosen the drain cock by turning it clockwise and empty all air and water, then tighten it counter-clockwise when you are done.

Water is the #1 enemy of electrical components in an onboard air system.
2

Replace the compressor air filter

Other than draining the tank, the main maintenance job is changing the compressor air filter. The filter keeps debris out of the compressor. Too much buildup makes the unit work harder, overheat sooner, and fill slower — and can lead to failure. Change the filter about every three months so the compressor stays fast and clean.
