Thunder Scientific Corporation ACS-1200 Air Compressor System 1-1
Document Number: ACS-1200.DOC - Edition 1 - July 2005
3 SAFETY GUIDELINES
All compressed gases, including air, can be dangerous. Know and follow all safety rules
when using compressed air and especially when disconnecting and venting compressed
air lines to install or modify equipment.
Always operate the ACS-1200 system in a clean, dry, well-ventilated area, free of
combustible materials, or solvent vapors. Operate the ACS-1200 in an open area at
least 12 inches away from any wall or obstruction that would restrict the flow of fresh air
to the ventilation openings. Restricting any of the ACS-1200 housing openings will cause
serious overheating leading to probable failure or possible fire.
Your ACS-1200 system is powered by electricity. Like any other electrically powered
device, if not used properly it may cause electric shock. Never operate in wet conditions
and never operate with cover removed. Failure to provide adequate grounding could
result in serious injury or death from electrocution. Make certain that the electrical circuit
to which the ACS-1200 is connected provides proper electrical grounding, correct voltage
and adequate fuse protection.
Attempting to operate the ACS-1200 with damaged or missing parts or attempting to
repair the ACS-1200 with protective cover removed can expose you to moving parts and
can result in serious injury. Authorized personnel should perform any repair required.
Repairs attempted by unqualified personnel can result in serious injury or death by
electrocution.
The compressed air directly from the ACS-1200 is not safe for breathing, and should
never be used to supply air for human consumption. The dried air from a membrane
dryer will contain less oxygen than normal air and under some conditions the dried air will
not meet breathing air standards for oxygen content. The air stream may also contain
carbon monoxide, toxic vapors, or solid particles. Breathing these contaminants can
cause serious injury or death.
This ACS-1200 can fall from a table or workbench causing damage to the compressor
and could result in serious injury. Always operate the ACS-1200 in a stable secure
position to prevent accidental movement of the unit.
Refer to attached 71R Series Rocking Piston Pump Operating and Maintenance Manual
for additional safety guidelines, hazard and warning information.
4 INSTALLATION
4.1 Unpacking
Unpack the ACS-1200 carefully and inspect it for any damage that may have occurred
during shipment. If there is shipping damage, notify the carrier immediately. Verify that
the power cord, air hose, and manual are present. If possible, save shipping container
for future use.
4.2 Location
Locate the ACS-1200 in a clean, dry and well-ventilated area. The system should be
located at least 12 inches away from the wall or other obstructions that will restrict the
flow of air to the ventilation openings. The compressor enclosure is designed to allow for
proper cooling; therefore ventilation openings must remain unrestricted to maintain
proper operating temperature.
Thunder Scientific Corporation ACS-1200 Air Compressor System 1-2
Document Number: ACS-1200.DOC - Edition 1 - July 2005
4.3 Hose Assembly
Apply Teflon tape (1 thread back from end of fitting) to hose fitting and assemble hose
fitting to air outlet of ACS-1200 using appropriate wrenches. Connect hose to fitting.
Connect other end of hose to the 1200 humidity generator.
Important: 1) The hex fittings on the air outlet of the ACS-1200 and the 1200 humidity
generator MUST be held in place with a wrench when tightening the fitting
and hose.
2) When tightening Swagelok tube fittings, tighten Swagelok nut only 1/4 turn
past finger tight.
4.4 Power
The ACS-1200 is equipped with a power receptacle and cord having a grounding wire
with an appropriate grounding plug. The plug must be used with an outlet that has the
same configuration as the grounded plug and has been installed and grounded in
accordance with all local codes and ordinances.
Power of the appropriate voltage, frequency, and current capacity, is applied via power
cord to the ACS-1200 power entry module.
4.4.1 Extension Cord
If an extension cord must be used, be sure it is a 3-wire extension cord that has a 3blade grounding plug, and a 3-slot receptacle that will accept the plug on the ACS-1200
and is 14 gauge or larger and no longer than 50 feet.
5 COMPONENTS and CONTROLS
5.1 Power Entry Module
The Power Entry Module (PEM) allows insertion of the removable power cord, houses
the On/Off power switch, and also houses the 10 amp time-delay fuse (FS1).
5.2 Hour Meter
The Hour Meter (HM1) tracks total run time of the ACS-1200 air compressing system.
5.3 Outlet Pressure Gauge
The Outlet Pressure Gauge (G1) indicates the regulated pressure available at the outlet
of the ACS-1200 air compressing system. This pressure is controlled by the outlet
pressure regulator.
5.4 Outlet Pressure Regulator
The Output Pressure Regulator (REG) controls the pressure available at the ACS-1200
outlet, which is indicated on the outlet pressure gauge. Turn slotted adjustment screw
clockwise to increase pressure and counterclockwise to decrease pressure.
Note: Pressures higher than 175 psi will be indicated by the "popping off" of the safety
valve and should be avoided.
Thunder Scientific Corporation ACS-1200 Air Compressor System 1-3
Document Number: ACS-1200.DOC - Edition 1 - July 2005
5.5 Air Compressor
The Oil-less Air Compressor (COMP) provides a maximum pressure of 175 psiG at a
flow rate of 10 liters per minute or more.
5.6 Membrane Compressed Air Dryer
The Membrane Compressed Air Dryer (AD1) is located after the air compressor and is
specifically designed to remove water vapor from the compressed air stream. Typical
pressure dew points of 0 °C or less are maintained.
5.7 Safety Valve
The Safety Valve (mounted on compressor) protects the system against pressures above
175 psiG. Pressures higher than 175 psi will be indicated by the "popping off" sound of
the safety valve.

6 GENERAL OPERATION
6.1 Start-up
Be sure the "Hose Assembly" of paragraph 4.3 has been completed before proceeding.
Insert the power cord into the ACS-1200 power receptacle. With the ACS-1200 power
switch in the off position, plug the power cord into an AC mains outlet of the appropriate
voltage, frequency, and current capacity.
Apply power to the ACS-1200 using the On/Off power switch. The compressor will start
and the outlet pressure gauge will indicate approximately 170 psiG.
6.2 Pressure Adjustment
If pressure adjustment is required adjust the output pressure to 170 psiG, during no-flow
conditions, by turning the slotted adjustment screw on the regulator clockwise to increase
pressure and counterclockwise to decrease pressure.
6.3 Shut-down
Disconnect power to the ACS-1200 using the On/Off power switch. The compressor will
shutdown and the pressure will slowly vent as indicated by the outlet pressure gauge.
Important: All pressure MUST
be vented before applying power again to the
ACS-1200 or the compressor will not start and will possibly blow the power input
fuse. All pressure must also be vented before disconnecting the air supply hose
or severe personal injury may result.

7.3 Shutdown and Storage Procedures
Proper shutdown procedures must be followed to prevent pump damage. Failure to do
so may result in premature pump failure. The non-lubricated compressor is constructed
of ferrous metals and/or aluminum, which are treated for corrosion protection but are still
subject to possible rust and corrosion when pumping condensable vapors such as water.
Follow the steps below to assure correct shutdown and storage between uses:
1. NEVER oil this non-lubricated compressor, as damage will result.
2. For long-term storage of the ACS-1200, disconnect the air hose and apply
power allowing the compressor to run "open" for at least five minutes. After
five minutes remove power and plug/cap outlet to prevent contaminants from
entering. The ACS-1200 is now ready for storage.
Warning: All pressure MUST be vented before
disconnecting air supply hose!
