ON-BOARD AIR SYSTEM
MOUNTING
Determine a dry place to mount your on-board air system. 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 system 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.
For proper heat dissipation of the compressor never install the on-board air system upside down.
Mark the spots for the holes with the mounting base as a guide and then drill. Make sure the system is
secured.
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.
PRESSURE SWITCH RATING
The included pressure switch has a rating of 90 PSI ON, 115 PSI OFF. When the air pressure in the air tank
is below the preset ON pressure (90 PSI), the compressor will automatically turn on and will start pumping air
into the tank. When the pressure reaches the cut OFF pressure (115 PSI), the compressor will be
automatically shut off.
In this system your Pressure Switch is already wired to the air compressor. Do not modify this connection.
AIR PRESSURE GAUGE
Your system includes a 150 PSI Pressure Gauge that will measure the air pressure of the tank.
The air pressure gauge is a sensitive part of the system, please avoid dropping, hitting or tighten it to the tank
using a method other than the brass nut located in the back.
DRAIN NUT
This nut 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 nut found at the tank’s bottom to drain the water from the tank. After draining the
accumulated condensation, apply thread sealant
to the nut’s thread and reinstall it.
IMPORTANT
: Draining the system regularly will extend the life of the air tank.
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
