TYPICAL INSTALLATION
AIR DRYERS AND AFTER COOLERS
An air dryer or aftercooler is installed directly in the air line.
MOISTURE REMOVAL AND AIR FILTRATION
As the air cools, moisture will condense in the lines. This moisture must be
removed before it reaches the tool being used. To remove this moisture, run the
main air line downhill to a moisture trap and drain. Air/water filters should also be
installed in the positions shown.
AIR PRESSURE REGULATION
Install an air regulator in the drop line for each tool, to regulate air pressure to
that tool. Never exceed the maximum pressure rating of the tool.
AIR LUBRICATION
Install an air lubricator only for those tools requiring lubrication. Do not use a
lubricator for paint spraying or similar applications. The oil will contaminate the
paint and ruin the job.
SHUT–OFF VALVES
Install shut–off valves in each drop line, to isolate the tool and its accessories for
servicing. You can also install a bypass line around an accessory.
COMPRESSOR CONTROLS
Refer to Fig. 4.
PRESSURE Switch (A)
This switch turns the compressor ON. It is operated manually, but when in the
AUTO position, it allows the compressor to start up or shut down automatically,
without warning, based upon air demand. ALWAYS set this switch to OFF when
the compressor is not being used, and before unplugging the compressor.
Pressure Relief Valve (B)
If the pressure switch does not shut down the motor when pressure reaches the
preset level, this valve will pop open automatically to prevent over pressurization.
To operate manually, pull the ring on the valve to relieve air pressure in the tank.
Tank Pressure Gauge (C)
This gauge measures the pressure level of the air stored in the tank. It is not
adjustable by the operator, and does not indicate line pressure.
