MAINTENANCE:
AIR STORAGE TANK-
To avoid the risk of
moisture in the air lines or tank failure, drain
the tank after every use or every four hours of
running time to prevent condensation build-up
and corrosion inside the tanks. To drain tank,
allow the compressor to fully pressurize and
then turn AUTO/OFF lever to the off position.
Remove power cord from the receptacle on the
end of the compressor case, then turn the
compressor on end with the tanks in the lowest
position (see Figure 3). Carefully and quickly
turn and open drain fitting. Tip unit toward
drain and allow water to drain out with the air.
AIR FILTER-
A dirty air filter will not allow the
air compressor to operate at full efficiency. If a
decrease in the supply air is noticed, it may be
necessary to replace the filter element. The
air filter is located inside the case just behind
the air output coupling. To replace, disconnect
hoses and unscrew the brass cylinder at the
mid-section. Remove filter disc and install a
new one (see Figure 4).
ELECTRICAL-
The motor of this compressor
has a thermal overload protector. If the motor
should overheat, the overload protector will
shut off the motor. If this should occur, turn
the compressor off immediately and allow the
motor to cool. Restart the compressor. If the
compressor fails to start, the compressor may
need to cool further before attempting to
restart. If the overload protector shuts the
motor off frequently, you may have a low
voltage situation. Low voltage can be
suspected when:
1. The motor does not get up to full power or
speed.
2. Lights dim when compressor is started.
3. Other motor operated appliances fail to
operate properly.
4. Compressor shakes or hesitates when
starting.
A primary cause of voltage drop is using an
extension cord that is not heavy enough to
carry the current the AA-74 compressor draws.
An under-size or over-length extension cord
will cause a drop in line voltage, resulting in
loss of power and overheating. Aseptico does
not recommend using an extension cord when
powering the AA-74 compressor unit.
RULES FOR SAFE OPERATION:
1. The compressor should be located in a dry,
clean, and well ventilated area.
2. This compressor needs no lubrication and
should never be oiled. Applying oil to any
part could result in polluted air delivery to
the air handling equipment.
3. If compressor is run for extended periods
of time, open case for more efficient
cooling.
4. All compressors generate heat even under
normal operating conditions. To avoid
serious burns, never touch the compressor
during or immediately after operation.
5. When unit is not in use, wrap cord and
store inside compressor. Do not abuse
cord.
6. Servicing should always be performed by
an Authorized Service Center.
7. ALWAYS use a grounded 3-prong plug-in.
