SYMBOL DEFINITIONS:
Type B Equipment
IMPORTANT:
If the electric power is interrupted by a
power failure, unplugging the power
cord, or by any other means, while the
compressor is running, turn the
AUTO/OFF lever to 'OFF' and then back
to 'AUTO' to relieve back pressure and
restart the compressor. If the power is
interrupted, follow these steps
immediately to prevent any motor
damage.
OPERATION
:
After unpacking the compressor, open the
case and locate the remote power cord
and air intake filter inside (see Figure 1).
Screw the air intake filter into the 1/4" NPT
hole in the top of the compressor head
assembly. Plug the power cord into the
receptacle on the outside end of the case
(see Figure 2) and then into a grounded
power outlet. The AA-74 compressor is
operated by an AUTO/OFF lever on the
top side of the pressure switch inside the
compressor case. By turning the lever to
the 'AUTO' position, the compressor will
start and stop automatically to maintain
pressure. The pressure switch is factory
adjusted to properly start and stop. To turn
the compressor off, turn the lever to the
'OFF' position.
1. After plugging the compressor in and
turning on, close the lid for operation. Let
the compressor run until it stops, indicating
full pressure.
2. Locate the air output 1/4" quick disconnect
and pressure gauge on the end of the
compressor case (see Figure 2). Connect
a 1/4" male coupling from your equipment
to the air output fitting. The pressure
gauge indicates pressure in the air storage
tanks and gives a visual indication that the
compressor is maintaining pressure
properly.
3. The AA-74 compressor will cycle on and
off as air is consumed during use. This is
normal for operation. Turn compressor off
if not used for extended periods of time.
