Hazards or unsafe practices that could result in minor personal injury or product or property damage.

PRECAUTIONS & WARNINGS
Air compressors are high-speed mechanical equipment requiring caution in operation to minimize harm to property and personnel. There are many obvious safety rules that must be observed in the operation of this type of equipment. Therefore not all safety precautions that must be observed with compressors and compressed air systems are listed here. Failure to follow any of these warnings may result in severe personal injury, death, property damage and/or compressor damage.
– Air from this compressor will cause severe injury or death if used for breathing or food processing. Air used for these processes must meet O.S.H.A. 29 C.F.R. 1910.134 or F.D.A 178.3570 regulations.
– This compressor is designed for use in the compression of normal atmospheric air only. No other gases, vapors or fumes should be exposed to the compressor intake, nor processed through the compressor.
– Turn off and lockout/tagout (per O.S.H.A. regulation 1910.147) the main power switch, then release all pressure from the system, before attempting to service or perform maintenance procedures.
– Relieve all pressure internal to the compressor prior to servicing per O.S.H.A. regulation 1910.147. Do not depend on check valves to hold system pressure.
– A properly sized safety relief valve must be installed in the discharge piping before (downstream) any shut-off valve, heat exchanger, orifice or any potential blockage point. Failure to install a safety relief valve could result in rupturing or explosion of some compressor or safety component.
– Do not operate the compressor over the A.S.M.E. pressure vessel rating for the receiver or the service rating of the compressor, whichever is lower.
– Do not change the pressure setting of the safety relief valve, restrict function of the safety relief valve or replace the safety relief valve with a plug. Over pressurization of some system or compressor component can occur, resulting in severe personal injury, death and property damage.
– Do not operate the unit with any of its safety guards, shields, or screens removed.
– Do not attempt to service any part of the unit while the compressor is operating.
– Never use plastic pipe or rubber hose not specifically rated for the necessary pressure and temperature, or lead-in soldered joints in any part of the compressed air system.

If for any reason any part of the manual becomes illegible or the manual is lost, have it replaced immediately. The owners manual should be read periodically to refresh one’s memory. It may prevent a serious or fatal accident.
– Never use a flammable or toxic solvent for cleaning the air filter or any parts.
– Make a general overall inspection of the unit daily and correct any unsafe conditions.
– Never play with compressed air. Reckless behavior of any kind involving compressed air can cause serious personal injury.
– Periodically check all pressure relief valves for proper operation.
– Any alterations to the compressor must have prior factory approval.
DESCRIPTION OF OPERATION
PRINCIPLES OF COMPRESSION CYCLES A reciprocating compressor is a piston type pump that develops pressure from the action of a piston moving through a cylinder. The cylinder, or cylinders, may be vertical, horizontal, or angular.
SINGLE STAGE – When air is drawn in from the atmosphere and compressed to its final pressure in a single stroke, the compressor is referred to as a “single stage” pump. During the downstroke of a single stage compressor, air is drawn through an intake valve in the head of the compressor and into the cylinder. At the bottom of the stroke, the intake valve closes and air is trapped in the cylinder. The air is then compressed in the cylinder during the upstroke of the piston.
TWO STAGE – Compressing air to higher pressure it is accomplished by using multiple stages. During the downstroke of the piston of a “two stage” pump, air is drawn through an intake valve in the head of the compressor, into the low-pressure cylinder and compressed during the upstroke of the piston. The compressed air is then released through a discharge valve in the head of the compressor to an intercooler where the heat resulting from compression is allowed to dissipate. The cooler compressed air is then drawn into a second compression cylinder, the high pressure cylinder, for compression to final pressure. From there the compressed air is released through a discharge valve to an air receiver tank. In one revolution of the crankshaft a compression cycle is completed.
APPLICATIONS Single estage compressors normally runs in the 95 up to 125 psi range. These pressure settings are designed to provide working air in the 90 up to 100 psi range that most air tools operate. These compressors are generally used in lighter duty applications such as in your garage at home.
A two-stage compressor normally run in the 145 up to 175 psi range. The higher-pressure setting of the two-stage unit is required in commercial and industrial applications that have tools and equipment such as in-ground lifts and tire changers that need air at higher pressure than a single stage compressor can provide. Two stage compressors are generally better suited for commercial use for several other important reasons. First, this high-pressure air is store in the tank as “available energy” so the compressor runs less. Secondly, two stage compressors run at much lower discharge temperatures so that you have cooler, dryer air in the shop air system. The two-stage compressor is more versatile because it gives the shop owner the ability to use the higher pressures when necessary but also use air regulated down of the 90 up to 100 psi range for normal air tools.

ENVIRONMENTAL GUIDANCE AND RECOMMENDATIONS
1. Disposal of Liquid Effluents The presence of liquid effluents or non- treated condensation from tank and separator in rivers, lakes or in other water receiving bodies may adversely affect the aquatic life and the water quality as well. The condensation withdrawn from the tank and separator, daily, according to the Preventive Maintenance Chapter, must be kept in a container and/or in an appropriate collecting network for further treatment. Schulz, the manufacturer of the product, recommends that the liquid effluent produced inside the receiver of the compressor or condensed separator should be adequately treated through processes that aim at protecting the environment and the healthy quality of life of the population, complying with the country’s current regulation requirements. Among the treatment methods available, one may choose the physical-chemical, chemical, and biological ones. The treatment may be carried out by the company itself or by outsourcing. 2. Draining the Lubricant Oil from the Compressor Unit The disposal of the lubricant oil coming from the lubricant oil change located in the crankcase of the piston compressor must meet technical requirements, as well as the regulation requirements of the current legislation of the country the product has been exported to. 3. Disposal of Solid Waste (parts in general and product packages) The generation of solid waste is an important aspect that must be considered by the users when using and maintaining their piece of equipment. The impacts to the environment may cause meaningful changes in the quality of the soil, in surface and underground water, and in the population’s health, due to the inadequate disposal of the discarded residues (on streets, water springs, landfills, etc). Schulz, the manufacturer of the product, recommends that the waste arising from the product, from its generation, handling, transportation, and treatment to its final disposal should the handled carefully. Appropriate handling should consider the following steps: quantification, qualification, classification, reduction at source, pick-ups and selective pickups, recycling, storage, transport, treatment and final destination. The disposal of solid waste must be carried out according to the regulation requirements of the current legislation of the country the product has been exported to.

DESCRIPTION OF OPERATION

SYSTEM COMPONENTS
Pressure Switch – The pressure switch senses the air pressure in the system and automatically starts the motor when the pressure drops below the cut in setting. Once the pump builds the pressure up to the maximum or cut out pressure, the pressure switch shuts off the motor and bleeds down the air pressure between the pump and check valve. This allows the motor to restart in an unloaded mode.
Check Valve – The check valve is a device that allows the air to flow in only one direction. While the compressor is running, the check valve is “open”, allowing the air to flow from the pump to the tank. When the compressor stops, the check valve is “closed” and keeps the air in the tank from trying to back up to the pump.
Pressure Relief Valve – This valve is often called a “pop-off” or a “safety relief valve”. Its job is to open up and relieve the air pressure in the event the pump did not shut off at the maximum setting.
Tank Drain Valve – This valve, also known as a petcock, is to drain out any condensation in the tank. Since some moisture will form inside the tank every time the compressor runs, it is important to drain the tank daily.
Intake Air Filter – As air is drawn into the compressor pump it must pass through a filter to remove dirt and dust. When the filter element becomes clogged with dirt it creates a high vacuum condition in the cylinder which can cause the oil from the crankcase to be sucked up past the rings and into the tank.
ON / OFF Switch – Starts and stops the air compressor. It is important to remember that in the “On” position, the compressor can start automatically. The compressor should not be turned off in mid-cycle using the switch (except in an emergency) so that the pressure switch is allowed to relieve the head pressure when it tums off the compressor.
Pressure Gauge – The pressure gauge reads the air pressure in the tank or air system.
SHUT OFF Valve – A ball or gate valve that is installed on the tank where the air is going out to the shop air system. This valve is used during scheduled maintenance to separate the compressor from the rest of the air system. It could also be important to quickly shut off the air from the tank in case of a problem like an airline breaking.
Cooling System – Air compressor pumps create remarkable amount of heat as they operate. Because so much heat is generated, the cooling system of the compressor is critical to the life of the pump. Compressor pumps are heavily finned to dissipate heat. Cooling air is blown over the fins by the fan blades designed into the flywheel of the pump. The inter cooler and after cooler lower the air temperature significantly, thereby making it easier to compress the air.

INSTALLATION

Location – The air compressor should be installed in a clean, dry, well lighted, and well ventilated area on a level floor. The flywheel side of the compressor should be towards the wall and the distance between the compressor and the wall should be a minimum of 30″ to allow for proper cooling air circulation, inspections, and maintenance.

! WARNING

Under no circumstances should a compressor be placed in an area that may be exposed to a toxic, volatile or corrosive atmosphere nor should toxic, volatile or corrosive agents be

stored near the compressor.

Mounting – Your compressor must be installed according to all applicable State and Local Laws. Shims may be needed to level the legs. Care must be taken when tightening anchor bolts. Uneven torque can lead to excessive vibration that can weaken welds and cause explosions. Tighten three leveled legs equally and leave the fourth nut loose.

AIR COMPRESSOR – OWNER’S MANUAL

INSTALLATION

Air Intake – Do not locate the compressor where it could ingest toxic, volatile or corrosive vapors or extremely dirty air. If a remote inlet filter is going to be installed you must increase one pipe size for every ten feet in length and use a flex hose between the pump and any solid pipe to minimize the potential of damage from vibration.
Piping – The main distribution line should not be any smaller than the pipe size of the shut off valve of the compressor. It is recommended that the shop air system be connected to the air compressor shut off valve with a flexible coupler to reduce the risk of damage from vibration. All airlines should slope to an accessible drain or moisture trap for removal of condensation. Make sure that there are no leaks in the airlines as even small leaks can cause your compressor to run outside of the rated duty cycle. A typical installation is shown on page 11, note that the feeder lines come off of the top of the main distribution line so that moisture can’t enter the feeder line.

! WARNING

ASME coded pressure vessels must not be modified, welded, repaired, reworked or subjected to operating conditions outside the nameplate ratings. Such actions will negate code status, affect insurance status and may cause severe personal injury, death and property damage.

! DANGER

High voltage may cause personal injury or death. Disconnect and lockout/tagout per O.S.H.A. Regulation 1910.147 all electrical power supplies before opening the electrical enclosure or servicing.

Wiring – Before starting the installation procedure, check that the building’s electrical service has an adequate capacity to handle the motor and the same electrical characteristcs (voltage, cycle, and phase). Install the compressor as close to the main power supply as possible and follow all National Electric Safety Codes as well as those dictated by State and Local authorities. A qualified electrician must do the electrical installation. Every compressor model has a specific power requirement and the wire size used is critical to a proper installation. The two tables (shown below) are for reference only and should not supersede specific National, State or Local code requirements. The compressor can be mannufactured without a power switch, according to the product version. The pressure switch must not be directly connected to the motor but to a control circuit. See “Electrical Diagram” page 5 and 6 to correct installation, according to the product version.

AIR COMPRESSOR – OWNER’S MANUAL

START-UP CHECKLIST

! WARNING

Never assume a compressor is safe to work on just because it is not operating. It could restart at any time. Follow all safety precautions and guidelines outlined in this manual.

Go through this checklist before you start the compressor for the first time.

! WARNING

Failure to perform the steps outlined in the start-up checklist, may result in mechanical failure, property damage, serious personal injury or even death.

1. Review Installation parameters in the prior section.
Double-check these items: – Distance from walls at least 30″. – Properly mounted. – Flexible coupler between compressor and shop. – No toxic, volatile, or corrosive fumes in the area. – Correct wire size, fuses, or circuit breakers.

2. Check the oil level in the pump and add if necessary. 3. Check that all pressure relief valves are in place and operational. 4. Check that the air filter is in place and securely mounted. 5. Remove all loose objects and tools around the compressor installation. 6. Open the service valve and any other shut off valves in the air system. 7. On three phase compressors, “bump” the motor to verify that you have the correct rotation (CCW facing the shaft).
Reverse if necessary.

BREAK-IN PROCEDURES
After completing the START-UP CHECKLIST you are ready to run the compressor. Always go through this procedure before restarting your unit, if you have moved it to a new location or have had service on the pump or motor.
1. Start the compressor and check for excessive noise or vibration. If there is any condition that appears unsafe, stop the compressor immediately and fix the problem. If the compressor is running normally, allow the unit to pump for ten minutes before closing the service valve and allowing the compressor to pump up and shut off. Check the system for leaks.
2. Pay close attention to the compressor for the first hour of use. It is not necessary to run the compressor “un-loaded” to seat the rings.
3. During the first full day of running the compressor you should note how many times an hour the compressor is starting. During an “average” hour you should check what percent of those 60 minutes the compressor is running. If the compressor starts more than eight times or runs for more than 75 percent of an average hour, you need more air.

BREAK-IN PROCEDURES
4. After eight hours of running, check the oil level and look for any oil leaks. Turn the compressor off and bleed down the tank pressure to about 20 psi and open the drain valve to allow all of the moisture to drain from the tank. Allow the pump to cool and torque the head bolts and the bolts which hold the inner and after cooler.
5. We recommend that you change your oil after the first 8 hours of operation. This could help remove any small particles in the pump and will improve the life of the pump.
6. After the first week of operation follow the guidelines in the MAINTENANCE SCHEDULE.
MAINTENANCE SCHEDULE
THE LIFE OF YOUR COMPRESSOR WILL BE DETERMINED BY HOW IT IS MAINTAINED.
– A clean pump will run cooler, causing less moisture in the tank and lines. Since the cooler the air is, the easier it is to compress, cleaning of the pump will make the motor and pump run less and save you money.
– A clean air filter will allow you to compress more air per ciyle. A dirty air filter causes the oil from the crankcase to be sucked up past the piston rings if happens you get MAJOR problems. First, the oil gets into your air system, mixes with the water vapor in the lines and creates a “mayonnaise” that can foul up tools and destroy paint systems with “fish eye”. Secondly, the oil becomes baked onto the valve plates where it builds up and cuts the efficiency of the pump dramatically.
– Clean oil at the proper level in the crankcase is your best insurance against pump failure.
– A dry tank will last many more years than a tank with water sitting in it rusting away metal. The tank is a great heat sink and will take out the bulk the moisture that is in your air system if you drain it.
WARNING Turn off power before servicing and be sure the air tank is unloaded. These instructions are based on normal operating conditions. If the compressor is located in an exceedingly dusty area, increase the frequency of all inspections.
DAILY – Inspect the compressor visually. – Check oil level and add some if necessary, before turning the compressor on. – Drain moisture from the piping system. – Be sure there is no excessive or unusual vibration or noise.
WEEKLY – Remove and clean intake air filters; do not wash the filter element. – Check V-belt for tightness. Belt tension should be adjusted to allow approximately 3/8″ to 1/2″ (9 to 13 mm) deflection with
normal thumb pressure, see Figure page 16. – Clean cylinders externally, cylinder head, motor, fan blade, tubing, and tank. – ASME safety valve should be tested manually to see if it is working properly.
MONTHLY – Check entire system for air leakage around fittings, etc by using water and soap lather. – Check the pressure switch operation. – Check for oil contamination and change it if necessary.

QUARTERLY – Change the air filter element every 300 working hours or quarterly. (Whichever occurs first). – Fasten bolts and nuts as required. – Change oil more frequently if compressor is located in a very dirty environment. – WHILE RUNNING IN A PERIOD OF ABOUT 100 WORKING HOURS THE OIL LEVEL SHOULD BE CAREFULLY
CHECKED.
ANNUALLY – Test and calibrate the pressure switch, pressure gauge and ASME safety valve according to their own technical
standards. These parts must be removed from the tank and pump to be tested. – Inspect and clean the suction and discharge valve(s) plate(s) every 1000 (one thousand) working hours (whichever
occurs first), located between the cylinder and its cover and, if necessary, replace it (them) according to the operation conditions.
LUBRICATION – The first oil change should be made after 8 hours of operation. – The second oil change after 40 hours of operation. – The third and following oil changes should be made after 200 hours of operation, or 60 (sixty) days, whichever occurs
first.
NOTE: Heavy Duty and multi-viscous oils are not adequate for Schulz air compressor’s lubrication. The same applies to oils that tend to emulsify. We recommend good industrial oil for air compressors, with rust and oxidation inhibitors and high viscosity level (from 90 to 95), SAE or ISO, as indicated in the table below:

SERVICE PROCEDURES

! WARNING

Never assume a compressor is safe to work on just because it is not operating. It could restart at any time. Follow all safety precautions and guidelines outlined in this manual.

CRANKCASE OIL – The oil level should be half way to three quarters up the sight gauge when the compressor is stopped. Do not over fill or check the oil level while the pump is running. Compressor must be level.

Use non-detergent, petroleum based, compressor or automotive grade oil only.

MAX

Detergent or synthetic oil can damage the pump, cause excessive leaks, and will void the warranty. DO NOT USE SYNTHETIC OIL IN THIS PUMP !

MAINTENANCE SCHEDULE

Change the oil when the compressor is warm so that the oil will drain out of the crankcase easier. Carefully open the plug on the crankcase drain, open the ball valve and drain the oil into a suitable container. Remove the crankcase fill plug to make the oil flow out faster. Allow the crankcase to drain completely. Replace the plug, and fill the crankcase to the proper level. Check the level carefully after the first day of use. Please recycle the used oil.

! CAUTION

Never attempt to change or fill the oil while the compressor is running. Do not work on the pump while it is hot as some parts of the pump can cause severe burns to unprotected skin. Never use flammable solvents to clean the pump or the intake system.

AIR FILTER – To service the air filter, remove the wing nut and cover that hold the element on to the intake assembly. Inspect the element and clean or replace as needed. Paper filters can be tapped out and back flushed with low- pressure air several times before they must be replace. Fiber (Micronite) filters can be washed out with soapy water, rinsed, and reused until the element material starts to deteriorate. Never use solvents to clean the filter or inlet parts. Always keep extra filter elements on hand. NEVER RUN THE COMPRESSOR WITHOUTA FILTER. Clean all parts and re-assemble in reverse order.
DRAIN THE TANK – To drain the moisture from the tank you should first reduce the air pressure in the tank and air lines to a safe pressure, around 20 psi. Open the drain valve and drain the moisture into a suitable container for disposal. All piston pumps have some level of oil bypass the rings and get pumped into the tank. This oil is measured in parts per million (PPM) and mixes with the moisture in the tank to form a whitish “mayonnaise” like substance. Check with local codes concerning the discharge of this fluid directly into the sewer system.
Compressors used in commercial applications should be drained at least once a day. If you only run your compressor occasionally, it should be drained after each time you use it. Shops that run multiple shifts a day should have automatic drains to help reduce the moisture build up in the tank. A 5 HP compressor can dump as much as a gallon of moisture a day into the tank.
VALVES – The compressor pump has a set of reed valves manufactured from the highest quality stainless steel. These valves and the valve plates that hold them in place need to be maintained in order for the pump to work at it’s normal capacity. Once the valves become caked with carbonized dirt and oil they loose their ability to open and close properly and the amount of air that the compressor can make is dramatically compromised. Before starting this maintenance procedure you should make sure that you have a set of the gaskets you need to replace when you open up the pump.
1. Remove the air inlet assembly, inter cooler, and after cooler from the cylinder head of the pump. 2. Remove the cylinder head bolts after loosening all of them evenly , from the center out. 3. Remove the cylinder head and valve plates from the cylinder. Separate the head from the valve plates taking care to note
the position of the valve plates for re-assembly. Use caution when separating the parts as the gaskets may be stuck together. Inspect the condition of the cylinder and piston for damage. 4. Clean the valves and valve plates with a stiff bristle brush or other suitable device. Do not use a steel wire brush as severe damage may result to the valve seat or valve. 5. Use clean safety solvent to loosen carbon deposits. NEVER use gasoline, thinners or other flammable solutions to clean valves or related parts. Remove all broken or defective gasket material. 6. To re-assemble the valve plates, a small amount of light grease or petroleum jelly can be used on clean, dry surfaces to hold the reed valves in place while they are assembled. Reserve the order to complete this operation and follow the recommended torque settings for the head bolts. Use a crosshatch pattem when tightening the head bolts. 7. Turn the pump over by hand several revolutions to make sure there are no problems. Review the START-UP CHECKLIST and follow the recommended BREAK-IN PROCEDURES. Re-torque the head bolts and check for leaks after one hour of running.

AIR COMPRESSOR – OWNER’S MANUAL

MAINTENANCE SCHEDULE

BELT TENSION – Proper belt tension and pulley alignment must be maintained for maximum drive efficiency and belt life. The correct tension exists if a deflection of 1/2″ occurs by placing 10 pounds of force midway between the motor pulley and the pump flywheel. See figure below. This deflection can be adjusted using the following procedure.

1. Remove belt guard. 2. Loosen the motor mounting bolts. Remove belts. 3. Shift the motor to the point where the correct tension
exists. 4. Retighten motor mounting bolts. Replace belts. 5. Check the tension again. 6. Replace the belt guard.

10 lb force x

x = 1/2” deflection

! WARNING

Do not operate the compressor with any of its safety guards, shields, or screens removed. Never cause the compressor to run at speeds in excess of the factory set RPM. Always follow all safety precautions and warnings when performing service.

PULLEY ALIGNMENT – Three examples of pulley misalignment are shown below. To check the pulley alignment, remove the beltguard and place a straight edge against the pump flywheel. Measure the distance from the straight edge to the motor pulley at several points. If the pulley needs to be adjusted, follow the procedure below.
1. Loosen the motor mounting bolts. 2. Loosen the setscrews on the motor pulley. 3. Align the motor pulley using the straight adge as a guide. 4. Retighten the motor pulley setscrew using thread-looking fluid. 5. Adjust the belt tension as described previously. 6. Retighten the motor mounting bolts. 7. Replace the belt guard and test.
