Safety Warnings and Important Information

WARNING: Always disconnect electrical power tocompressor before servicing.

WARNING: To prevent injury from high pressure air,never remove coalescing filter bowl or any otherpressurized component until purge cycle has endedand system has been relieved of air pressure byopening service drain valve.

WARNING: Compressor heads are extremely hotduring operation. To avoid burning yourself, allowunit to cool before servicing.

WARNING: Compressor motors are thermallyprotected with an automatic reset and may restartwithout warning.

WARNING: Compressor motors are controlled by apressure switch and will have line voltage applied tothem whenever the tank pressure is below 80 PSI.The compressor may start without warning.

IMPORTANT: Installations must be made to all localcodes.

CAUTION: Adequate line voltage is essential toproper compressor operation. Voltages outside thespecified range in Section 2.1 require a buck or boosttransformer. Otherwise, failure to start, circuit breakertripping, overheating and compressor damage mayoccur.

CAUTION: Excessive circuit lengths should beavoided to reduce voltage drop during compressoroperation. Voltage measurements should be takenwhile the compressor is running. A static voltagereading is not a true indication of voltage supplyduring operation.

CAUTION: Compressors installed outdoors must beprotected from rain, snow, direct sunlight and excessdust. Temperature limits and ventilationrecommendations must also be followed.

CAUTION: On OL-7 and OL-10 units, always keepboth service switches in the ON position. Never runthe compressor with one head turned OFF except forshort periods of time while one head is notoperational.

CAUTION: Never turn a compressor head ON whileother head is running as the heads will not start underback pressure. Allow the pressure switch to shut offthe compressor at 100 PSI or disconnect thecompressor main power supply to relieveline pressure through the solenoid valve.

completely

CAUTION: To avoid compressor overheating andthermal shutdowns, the installation site must beproperly ventilated and, if necessary, air conditionedto prevent ambient temperatures from exceeding104°F/40°C.

SECTION 1.0 ABOUT AIRMAX OL-SERIES COMPRESSORS

1.1 Compressor Features

See the Matrx DentalEquipment Catalog for additional information) Thesecompressors are available in 3-, 7- and 10-userconfigurations.

AirMax Oil-less compressors combine high-performance design with rugged, trouble-freeconstruction to provide high quality compresseddental air. Built with high-reliability oil-less pistoncompressor heads, they feature an integral desiccantdrying system and in-line filter to ensure delivery ofclean, dry air that is free of water, oil and othercontaminants that could compromise dentalprocedures and handpiece operation. Air is stored in

an ASME-certified tank. All units are also equippedwith a low voltage relay to enable operation from aremote location. Optional sound-reducing covers areavailable for all configurations (

1.2 Compressor Flow Diagram

for several seconds

During the operating cycle, compressed air flows fromthe compressor head through an aftercooler (a coilwrapped around the purge tank). The cooled air thenpasses through a coalescing filter that removesparticulates. From the filter, the air streams flows upinto the desiccant tank, through desiccant beadswhich extract moisture. Dry compressed air is nowstored in the main air receiver tank, as well as thepurge tank. Apressure switch monitors air pressure inthe receiver and shuts off the compressor motor when

pressure reaches 100 psi. It restarts the motor whenpressure drops below 80 psi.

During the purge cycle, the compressor motor shutsoff and the solenoid valve opens, releasing a smallburst of air. After this, a slow stream of air (stored in thepurge tank) continues to flowthrough the desiccant tank, coalescing filter, and outthrough the solenoid. This cycle removes moisturebuilt up in the desiccant tank, as well as particulatesfrom the coalesing filter.

Check main circuit breaker. Turn off “fully” then turn on “firmly”.If circuit breaker tripped, measure voltage at line side of pressure switch

. The maximum voltage range that OL-3/7/10may operate at is 207-253 VAC. The voltage range for OL-3 115 is 103-126 VAC. Voltage outside of this range may result in failure to start, circuitbreaker tripping, overheating and compressor damage. Install a buck orboost transformer as required.Check for excessive circuit lengths, as they can cause voltage drop duringcompressor operation.Check circuit breaker at top of each head. If activated (button out) waitapproximately 15 minutes for head to cool. Press button in to reset.On OL-7 and OL-10: Isolate each head by turning off one motor at a time.If each compressor head runs with the other turned off, but do not runtogether, the voltage is too low. A boost transformer is required.Check fuse at compressor electrical control box. When reinstalling fuse,firmly press fuseholder in place.Check all electrical connections.If using remote control: Disconnect red and white wires at compressorelectrical box from the remote control wires and twist together to bypassswitch. If compressor runs, replace remote switch or inspect remote controlwiring.If not using remote control: Make sure the red and white wires at thecompressor electrical box are securely twisted together.Momentarily press in the center button of the contactor (inside the electricalbox). If compressor runs: Check the transformer output at the yellow andbrown wires. If voltage is not approximately 24 volts, replace transformer.If voltage is 24 volts, replace contactor. Do not “jam” contactor button.

See safety warnings aboveCheck that installation site is properly vented and, if necessary, airconditioned to prevent ambient temperature from exceeding 104°F/40°C.Check if air intake filters are clogged.Verify that the compressor is properly sized for the number of users at theinstallation site (see Section 2.2).Check for leaks within compressor and piping system causing compressorto overcycle.If a sound cover is installed, check for cooling fan operation.

-If fans are operating, check that fan openings are not blocked.-If fans are not operating, check that fan wire harness is connected tocompressor electrical box. If so, replace fans. Do not reinstall toppanel until fans are operational.

Allow approximately 15 minutes for head(s) to cool and thermal protectorsto reset.

Replace start capacitor.

Check that motor switch is in the “ON” positionCheck motor switch. Cycle off and on (for dual headunits, make sure other head is off during this test - seecaution at head of Troubleshooting section).Check circuit breaker at top of head. If activated (buttonout) wait approximately 15 minutes for head to cool.Press button in to reset.

Clean or replace check valve.

Check for leaks by allowing the compressor to reach 100psi and shut down. Close the receiver tank outlet valve toisolate compressor from piping system.

If the pressure gaugecontinues to drop while outlet valve is closed, the leak iswithin the compressor. If the pressure gauge maintainsthe same reading, but drops after opening the outlet valve,the leak is in the piping system. The pressuregauge drops a few psi each time the compressor turns offat 100 psi.

Replace filters per section 4.2.

Check wire connections to solenoid purge valve.Replace solenoid valve. The solenoid purge valveis normally open (closed when the compressor runs).

Clean ports.

Check all wiring connections to solenoid valve.Replace solenoid valve.

Check flow indicator on top of coalescing filter. If greenwhile compressor is running, the filter element is OK. Ifred while compressor is running, the filter is saturated ordeteriorated and must be replaced. After replacing, rununit for a few days. If water is still present, replacedesiccant tank.

Replace desiccant tank.

Check for leaks within compressor and piping systemcausing compressor to overcycle.Compressor is undersized (see Unit Selection Guide,Section 2.2). Upgrade to larger compressor.

CAUTION: Beforedisassembling or removing check valve, closereceiver tank outlet valve and open tank drain valve torelieve compressor air pressure.

Do not use anyair from piping system for 1 hour.
