INTRODUCTION
Allied Healthcare's ARIDYNE ™ Air Compressors are
designed to withstand a heavy workload. Their
construction includes both a special quieting material
and drying system. The special quieting material in the
ARIDYNE ™ eliminates annoying pump and fan noise. The
drying system reduces condensation in air lines and
provides cool, clean air. Casters make the air
compressor easy to move from room to room.

WARRANTY
Because the ARIDYNE ™ 3500 Air Compressor is
quality designed, Allied Healthcare Products, Inc.
promises to repair or replace any defective parts at no
cost, including labor, for one full year from date of
purchase. This is the extent of AHP responsibility. All
consequential damages are specifically excluded.
PRECAUTIONS
e DO NOT use the compressor in the presence of
flammable anesthetics.
eo CAUTION: To prevent electrical shock hazard refer
all servicing to qualified service persons.
® Electrical components inside the compressor system
are isolated from ground.
e The air compressor system is grounded. DO NOT
plug it into ungrounded outlets or adaptors.
e® The compressor is of the oil-less type and MUST
NOT be lubricated.
® Never put oxygen into the compressor. The electrical
components are not approved for oxygen use.

Precautions Continued
e It is recommended that you install a transparent
water trap at the inlet of your blenders, respirators,
etc. to protect them from moisture in case the drying
system of your compressed air source (portable
compressor or piped) fails. The water trap should be
checked and emptied during each patient visit. If
your equipment did not come equipped with a trap,
contact your local dealer for information on AHP's
F-100 Condensation Trap.
e Saline solutions can cause the valve plates inside
the air pump to corrode. This lowers the
compressors operating pressure and performance.
Whenever applicable, isolate the air compressor
from environments in which saline solutions are
used.
e Do not substitute parts without permission from the
Allied Healthcare Products, Inc. Service Manager.
Such substitutions can cause premature product
failure and may void warranty.

IMPORTANT UNPACKING
INSTRUCTIONS
1. Unthread the six Phillips screws on the side panel
and remove the panel.
2. Loosen and remove three nuts and bolts attached
to pump bracket, on the bottom of the pump.
3, Loosen, butdo not remove the three 5/1 6-18 hex
nuts securing the tie down straps to the angle on the
side of the cabinet.
4. Swing the tie down straps (either up or down)
toward the cabinet.
5. Reattach the three nuts and bolts removed in
instruction #1 to the tie down straps.
NOTE: Reverse these instructions when preparing
the unit for shipping.
6. Tighten all hex nuts.
7. Check to see that the drainage hose is positioned in:
the foam in the water tray.
8. Examine the compressor for shipping damage and
replace the side panel.
CONTROLS AND FEATURES
Power Switch: turns the compressor on and off.
Elapsed Time Indicator: measures how manv hours the.
Aridyne 3500 has been used.
Performance Gauge: indicates how well the
compressor is operating.
Green: Safety — indicates 50 psig outlet pressure
and 5*F or greater dew point depression.
Unit may run continuously. Hook-up may be
remote.
Yellow: Waïning — indicates 45-50 psig and low
dew point depression. Hook-up should be
very close. The needle should only enter the
yellow area occasionally and should not stay
in the yellow for long or the drainage system
will be impaired.
Red: Danger — indicates limited drying, less than
50 psig outlet pressure and flow capacity
exceeded. Unit should NEVER be operated
in the red.

OPERATION
1. Position the compressor so there is plenty of air
space in front and behind it. Good air circulation can
prevent overheating.
2 Insert the plug into a proper hospital grade outlet.
DO NOT use ungrounded outlets or adaptor plugs.
3. Turn the power switch “ON.” (Check valves in the
outlets allow you to attach equipment when the
compressor is on.)
DO NOT use wrenches or excessive force in attaching
equipment to the outlets. This could damage internal
tubing.
4. DO NOT operate the compressor for extended
periods of time if the performance gauge is in the
yellow. NEVER operate the unit if the gauge is in the
red.
5. The compressor can be started with pressure in the
system.
ROUTINE MAINTENANCE
A. DAILY
1. Locate the cabinet inlet filter (Fig. 3, Нет 1).
2. Clean the dust and lint from this filter daily. At least
once a week remove it and wash it in warm soapy
water.

5. Loosen the clamp on the drainage tubing (Fig.7, item 21)
and pull it up through the shelf.
6. Carefully slide the motor/fan shelf out enough to expose
both pump inlet filter assemblies (Fig.4). Do this slowly to
avoid putting excess stress on wires.
7. Clean or replace the pump inlet filter elements (Fig.4).
a. Unthread the jars (1) from their lids.
b. Pull out the center studs (2).
c. Wash the elements (3) with clean water and air dry, or

d. Reassemble.
FIG. 4
C. YEARLY: Install the Preventive Maintenance Kit.
(See REPLACEMENT PARTS for part numbers.) It
includes the following:
2 Pump Inlet Filter Elements
1 Water Trap Filter Element
1 Water Jar O-Ring
6 Cabinet Inlet Filters
1 Relief Valve Diaphragm
1 Regulator Diaphragm
1. To install the pump inlet filter elements, refer to
QUARTERLY.
2. To replace the water jar filter and O-ring (Fig. 5):
a. Remove the rear panel.
b. Disconnect the tubing from the bottom of the
water jar (1). Loosen the clamp (Fig. 7, item A)
and unthread the jar.
Unthread the retainer cap (2) and remove the
filter (3).
. Clean the water jar with warm soapy water.
. Install the new water jar filter and reassemble.
When reassembling, carefully place the new

AFTER 6,000 HOURS/
PUMP OVERHAUL KIT
After 6,00 hours of use, install the pump overhaul kit,
even if the Aridyne 3500 is operating properly. The
overhaul kit prolongs pump life without major
rebuilding. See the replacement parts list for the part
number.
Service life of Aridyne 3500 will be shortened if it is
operated in a hot environment (90°F/32°C or above). If
this is the case, install the kit more often than every
6,000 hours.
Instructions are included with each kit. Before using the
kit, follow these instructions to remove the shelf/pump
assembly:
1. Unplug the power cord.
2. Remove the rear panel.
3. Disconnect the copper tubing at the compression
fitting (Fig. 7, item B) above the shelf.
4. Disconnect the tubing from the bottom of the water
jar (Fig. 7, item 3), loosen the clamp (Fig. 7, item A)
and unthread the jar.
5. Disconnect the tubing from the relief valve (Fig. 7,
item 2) and pull it down through the shelf (Fig. 7,
ltem D). |
6. Slide the shelf entirely out of the cabinet.
CAUTION: Be extremely careful not to bend the fan
blades. This can severely affect the cooling
and performance of the Aridyne 3500.
7. Remove the pump wires from the termina! block
(Fig. 7, Item C).
8. Lay the shelf down on its side and spread the
springs (Fig. 7, Item 10) open at the four pump
eyebolts. Unhook the springs from the pump to free
the pump from the shelf.
9. Proceed with the pump overhaul, using instructions
included with the kit.
NOTES: © When installing rings in the air pump, be
sure the piston is exactly flush with the
cylinder when the piston is at top dead
center. Readjust the cylinder as necessary.
e |f you have questions, please contact Allied
Healthcare Products, Inc.
e |fthere is excessive damage to the pump,
such as broken pistons, scored cylinders,
etc., contact Allied Healthcare Products,
Inc. to make proper arrangements for
factory repair.

RESYNCHRONIZATION
1. With the rear panel off, plug the power cord in and
turn the power switch on.
2. Pull the regulator locking ring (Fig. 6, item 12) and
turn the regulator adjustment knob (Fig. 6, item 13)
clockwise until it is completely closed.
3. If the performance gauge does not read at the “P” of
PSI in the GREEN area at a no-flow condition, pull
out the relief valve locking ring (Fig. 6, Item 13) and
turn the adjustment knob until it does.
CAUTION: DO NOT adjust the needie past the
- “P” in the green area or pump
damage will result!!!
4. Once the relief valve knob is adjusted properly, push
the locking ring in to lock the setting.
5. Attach a pressure gauge to either of the Aridyne
3500 outlets. |
6. Adjust the regulator until the outlet pressure is
approximately 55 psig at a no-flow condition. After
each adjustment, allow a few seconds for the
system to stabilize.
7. Push the regulator locking ring in to lock the setting.
