5) Inspect the compressor to makesure that all the fittings, bolts, etc.,are tight and secure before startingthe compressor.
6) Do not touch the compressor ormotor while it is in operation.These parts become HOT duringnormal operation. Allow the unit tocool completely before performingmaintenance or repairs.
7) Do not increase the settings oncontrol components. Thesesettings provide safety againstover pressurization. The pressureswitch settings are preset at thefactory for normal operatingconditions and increasing thesettings will result in compressorand motor damage.
8) Regularly inspect the hoses,plugs, fittings, piping, wires, etc.,for signs of damage, weakness orleakage before starting and usingthe compressor.
9) Fast moving air can stir up dustand debris, which may be harmful.Release the air slowly whendraining moisture ordepressurizing the unit.
10) Tanks rust and weaken withmoisture. Ensure the tank isdrained daily to avoid rustformation.
11) Inspect the air tank for rust, pinholes, cracks (especially in rearwelds), bulges and other changesin the tank.
12) Never weld or drill holes in theair tank.
13) Keep others at a safe distancefrom the work area.
SPRAYING PRECAUTIONS
1) Always wear a respirator andsafety glasses when spraying.
2) Always spray in an open, well-ventilated area to prevent fumesfrom accumulating and causing fireand health hazards. Fumes aredangerous.
3) Do not spray materials nearopen flames and electricalequipment.
4) Do not smoke while sprayinginsecticides, paint or otherflammable substances.
5) Do not direct paint or othersprayed material at thecompressor. Make sure thecompressor is as far away from thespraying area as possible tominimize overspray accumulationon the compressor.
6) When spraying solvents orchemicals, follow the instructionsthat are provided by themanufacturer.
7) Never use air pressurizedaccessories or parts in the airsystem that are not suitable for150 PSI.
When high humidity is present orwhen a compressor is used for anextended period of time, moisturewill collect in the tank. Thiscondensation can cause waterdroplets to appear in paint that issprayed. To eliminate thismoisture, drain the tank often toreduce the buildup. A filter in theair line can help eliminate thismoisture when it is located as nearto the gun as possible.
INSTALLATION
In order to receive maximumperformance and long life fromyour compressor, the followinginstructions should be readcarefully and all points regardinginstallation and operation of theunit should be noted andobserved. Carefully reading thismanual before connectinganything to the motor orcompressor is necessary foroptimum trouble-free operation.
INSPECTION
Check for possible damage fromtransit and test the pulley byturning it freely with your hands.Report and damage to thedelivery carrier immediately.
LOCATION
Select a clean, dry, and well-litlocation. In cold climates, thecompressor should be installed ina heated building. Insulate coldwater or other low temperaturepipes that pass overhead to avoidpossible collection and drippingcondensate onto the compressormotor that could cause rustand/or motor shorting. DO NOTinstall the compressor in a boilerroom, paint spray room, or areawhere sandblasting occurs. Ifacid or dust is in the air where thecompressor is operating, thecompressor intake should bepiped to the outside. This intakepipe should be increased onepipe size for every twenty (20)feet of run and the intake filtershould be installed at the end ofthe pipes with a hood to protectthem from the elements. Specialsize filters are required for pipeaway.
If the compressor has to belocated where the motor will be
3
exposed to appreciable quantitiesof water, oil, dirt, acid, or alkalinefumes, the motor must be ofspecial construction to avoid rapiddeterioration; I.e. TEFC.
Unless the base is exactly level,shims will probably be required.Any space between base and footshould be shimmed rather thandrawing the foot down thus placingstrain on the unit. When unit isproperly shimmed, vibration will beat a minimum.
Allow sufficient space around thecompressor so that it is accessiblefrom all sides for maintenance.Mount the unit with the pulleytowards the wall at leas 18 inchesbetween pulley & wall.
POWER SUPPLY & WIRINGWARNING: Installation shouldbe executed by a licensedelectrician.
NOTE: All electrical connectionsmust be tightened before starting.This includes connections to themotor junction as well as theCondor Switch or Magnetic Starter.This shall include all factoryconnections. Repeat: Check ALLelectrical connections beforestartup.
Wiring should be installed by alicensed electrician who is familiarwith requirements of the NationalBoard of Fire Underwriters and ofwhat the local inspectorsrecommend. Consult your localelectrical contractor regardingelectric codes and recommendedwire sizes.
SINGLE PHASE MOTORS:
Hook your hot leads to the wiringterminals opposite of the motorswires. Hook one hot lead to 1L1.Another hot lead to 3L2. Hookground wire to our ground wire.
THREE PHASE MOTORS:
Hook one hot lead to 1L1 lug, hookanother to the 3L2 lug and thenhook the third to 5L3. Run groundwire to our ground lug. Startcompressor and check for rotation.If rotation is reversed, shut offpower and switch two (2) of the hotleads. This will reverse the polarityand the motor will run the oppositedirection.
Note: Make sure that your powersupply and internal wiring areadequate and that the availablefrequency and voltage correspondto the motor nameplate andstarter. A 230 volt motor will notwork sufficiently on a nominal 208volt system. Even if the actualvoltage is up to 208 volts, the
10-12 volt drop during start-up(this is average, but not a highfigure for commercial buildings)may cause the motor to labor andblow fuses or heater elements.Do not accept the nominal figurefor line voltage, but rathermeasure it with a voltmeter duringa period of maximum powerdemand.
AIR INTAKE
The compressor is equipped withan intake filter that requires nopiping. If it is necessary to pipethe intake outdoors, see theinstructions in this manual.
PIPE CONNECTION
A flexible connector should beused between the compressortank and the building piping orconnection to after cooler or othersimilar equipment in order tominimize noise, vibration,vibration damage, and wear andtear.
CAUTION: Never install a shut-off valve (e.g. glove or gate valve)between the compressordischarge opening and thereceiver unless a safety valve isinstalled in the line between thisvalve and the compressor.
Never operate the pump at apressure or speed in excess ofthose recommended by thefactory.
TANK
Tank feet should be placed onvibration isolator pads (1/4” thickor less) available through yourdealer. Anchor bolts should begently snug, but not tight, toallow for vibration. Remember,the bolt is only a guide to holdthe compressor in place. Do not

over tighten the legs of the tankagainst the pads, it will damageyour tank.CAUTION: DO not storetank on dirt or on an unevensurface. Over time, the tank will tiltcausing the pump to fail from lackof lubrication.
STARTING
• Check oil level before starting.The oil should be in the center ofthe sight glass.
• Turn the compressor over a fewrevolutions by hand to make surethat everything is free.
• Check belt tension. (Should be1/2” of play.)
• Remove rags, tools, and anyother objects from the vicinity ofthe compressor.
• Never put hands on the belts ofan idle unit unless you are sure themain motor switch is off.
• Note the direction of the arrowstated on the belt guard and besure rotation is the same directionwhen running. Correct direction iscounter-clockwise when standingfacing the flywheel. Air should bedrawn through the intercooler ontothe cylinders for maximum cooling.
OPERATION & CARESERVICE
All units are shipped with break-inoil. Oil should be changed withinthe first 50 hours or 30 days of use(whichever comes first). Use aMobil RARUS 427 which isavailable through your dealer orany non-detergent 30W aircompressor oil. WARNING: DONOT USE AUTOMOTIVE TYPEOIL.
• Oil should be changed every 90days. Oil level should be halfwaylevel in the sight glass.
• If oil is milky an oil change will berequired.
• Inspect air filters weekly andclean or change as needed.
BELT ADJUSTMENT
Always pull the motordisconnect switch beforeworking on the belts so themotor cannot start upunexpectedly. When belt tensionis adjusted properly, the belts canbe depressed at a point midwaybetween the motor pulley and theflywheel approximately one halfinch. Loose belts will slip on themotor pulley and cause excessiveheating and wear. A belt that is tootight will overload the bearings.Adjustments can be made bysliding the motor along its base.When installing new belts, it isnecessary that the motor bolts beloosened and the motor movedtoward the compressor. The newbelts can be installed withoutdamage or strain. Over time beltsstretch and it is recommended thatall belts be changed at the sametime. To adjust the belts, loosenthe four motor frame nuts andadjust the single bolt head on thebelt tensioner. (Figure 1)
DAILY CARE
• Check oil level in crankcaseand, if necessary, add sufficientoil to bring to (but not above)halfway level in the sight glass(without the motor running).
• Drain moisture from air receiver.(Figure 2)
• Stop, look, and listen forunusual noises, failure tocompress, overheating, vibration,or belt slippage. Correct beforedamage occurs.

- Change compressor oil
Replace oil more frequently whenused in dusty operatingenvironments.
CHANGING THE OIL
1) Place oil drain pan below the oildrain plug.
2) Remove oil cap to allow the airto enter the crankcase.
3) Remove oil drain plug.
4) Allow oil to drain completely.
5) Clean and replace oil drain plug.
6) Refill crankcase with SAE 20 orSAE 30 weight non-detergent oil tothe red dot on the oil level sightglass. Be careful not to overfill thetank.
Do not use multi-grade, ATF,hydraulic fluid, two-cycle oil or anyother improper oils because it willvoid the warranty. Usingautomotive engine oils may causecarbon deposits on valves and canshorten valve life.
Changing Filter
Never run the compressor withoutan intake air filter or with a cloggedintake air filter. Use compressedair to blow the filter clean. If thefilter
