SECTION 1 SAFETY Safety First At Quincy Compressor safety is not only a primary concern, but a faithfully performed practice. Beginning with the design stage, safety is built into “The World’s Finest Compressor”. It is the intention of this manual to pass along the “safety first” concept to you by providing safety precautions throughout its pages. “DANGER !”, “WARNING !”, and “CAUTION !” are displayed in large bold capital letters in the left hand column to call attention to areas of vital concern.
•Allow ample time for the compressor to cool before performing service pro cedures. Some surface temperatures exceed 350°F when the compressor is operating. •Per OSHA regulation 1910.147, relieve the system of all pressure before at tempting to service any part of the unit. •Do not operate the unit with any of its safety guards, shields, or screens removed. •Do not remove or paint over any DANGER!, WARNING!, CAUTION!, or instructional materials attached to the compressor.
•Provisions should be made to have the instruction manual readily available to the operator and maintenance personnel. If for any reason any part of the manual becomes illegible or the manual is lost, have it replaced immediately. The instruction 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.
SECTION 2 SYSTEM DYNAMICS Description & Application The Quincy Compressor QR-25 Series consists of heavy duty industrial, belt driven, single or two stage compressors. Single stage compressors are capable of delivering up to 100 PSIG continuously. Some single stage compressors are capable of delivering up to 150 PSIG intermittantly (with proper controls and modifications).
Principles of Lubrication Systems Moving parts within the crankcase are supplied with lubrication by a posi tive displacement, gerotor type oil pump. Oil is drawn up from the bottom of the crankcase to the oil pump through an oil sump strainer screen. The oil is then forced under pressure through the oil filter (if so equipped).
for compressed air. The idea is to create compressed air on demand, but to limit the number of times a motor must start the compressor in a given time period. To prevent motor burnout, the motor should be limited to no more than six (6) starts per hour. UNLOADER TOWERS FROM THE AIR RECEIVER Control Version P : Describes a basic compressor with no added control features. HYDRAULIC UNLOADER Pix 1069 Pix 1069 Fig.
The manual shutoff allows for the selection of either “start/stop” or “con tinuous run” control. In either situation, the hydraulic unloader protects the compressor from excessive damage caused by a drop in oil pressure.
SECTION 3 INSTALLATION Receiving Delivery Immediately upon receipt of compressor equipment and prior to completely uncrating, the following steps should be taken: CAUTION ! Step 1) Inspect compressor equipment for damage that may have occurred during shipment. If any damage is found, demand an inspection from the carrier. Ask the carrier how to file a claim for shipping damages. (Refer to SECTION 3, Freight Damage for complete details.) Shipping damage is not covered by Quincy Compressor warranty.
ment at the premises where the delivery was made. Do not move the damaged freight from the premises where the original delivery was made. Retain all containers and packing for inspection by the carrier. A claim form can be requested from the carrier: Standard Form for Pre sentation of Loss and Damage Claims (form # 3208). Your claim will need to be substantiated with the following documents: a.) form #3208 b.) original bill of lading c.) original paid freight bill d.
and local laws governing acceptable noise levels. Check with local officials for specifications. Excessive noise can be effectively reduced through various methods. Total enclosures, intake silencers, baffle walls, relocating or isolating the compressor can reduce noise levels. Care must be taken when constructing total enclosures or baffle walls. If not properly constructed or positioned, they could contribute to unacceptable noise levels or overheating.
Mounting Proper mounting of Quincy compressor units is crucial to the safe operation and longevity of the equipment. The installation requires a flat and level concrete floor or pad (for mobile units see Mounting Mobile Units). Satis factory results can usually be obtained by mounting horizontal tank units on vibration isolators available from your local Quincy distributor. All vertical tank units must be anchored! Quincy recommends that all vertical tank units be mounted as indicated without isolators.

WARNING ! Excessive compressor RPM’s (speed) could cause a pulley or sheave to shatter. In an instant, the pulley or sheave could separate into fragments capable of penetrating the belt guard and causing bodily harm or death. Do not operate the compressor above the recommended RPM (refer to SECTION 2, Specifications). Guards All mechanical action or motion is hazardous in varying degrees and needs to be guarded.
conditions, when properly serviced, in accordance with the maintenance sec tion of this manual. If, however, the compressor is to be installed in a location where consid erable dust, dirt and other contaminants are prevalent, consult your local Quincy distributor for advice and optional filters. A condensate trap must be installed as close as possible to the inlet filter if, as a result of installation or environmental conditions, there is any risk of moisture forming in the inlet piping.
Pnuematic Circuit Breakers or Velocity Fuses The Occupational Safety and Health Act (OSHA), Section 1926.303, Paragraph 7, published in the Code of Federal Regulations 29 CFR 1920.
WARNING ! Follow ASME code for air receiver tanks and other pressure containing vessels. Pressure vessels may 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 property damage, severe injury or even death. WARNING ! Always replace worn, cracked or damaged receivers. Do not use plastic pipe (PVC) anywhere in a compressed air system. Serious injury or death could result.
air tank is dependent upon an internal tank pressure of 20 to 30 PSIG (no more than 30 PSIG). Higher internal tank pressures are dangerous and could cause serious injury! WARNING ! Oil and moisture residue must be drained from the air receiver daily or after each use. Accumulations of oil residue in the receiver can be ignited by embers of carbon created by the heat of compression, causing an explosion, damage to property and injury to personnel.
Read and understand the instruction manual WARNING ! Drain the tank WARNING ! Condensation could cause rust resulting in reduced wall thickness and risk of explosion.
SECTION 4 START-UP & OPERATION Pre-starting 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 outlined in SECTION 5, Stopping For Maintenance. WARNING ! Failure to perform the pre-starting checklist may result in me chanical failure, property damage, serious injury or even death. Steps 1 through 12 should be performed prior to connecting the unit to a power source.
Step 13) Jog the starter switch to check the rotational direction of the compressor.It should agree with the rotation arrow embossed on the compressor sheave. Step 14) Check for proper rotation of the cylinder cooling fan (fins inside sheave). The fan should blow cooling air across the cylinder. Initial Starting & Operating This instruction manual, as well as any instructions supplied by manufacturers of supporting equipment, should be read and understood prior to starting the compressor.
A new or rebuilt reciprocating compressor should be run for a total of 100 hours at full discharge operating pressure to break-in the new piston rings. Until the rings are seated, the compressor will discharge higher than normal amounts of lubricant. In light of this fact, the lubricant level should be checked more frequently during the 100 hour break-in period.
SECTION 5 MAINTENANCE & LUBRICATION Stopping for Maintenance The following procedures should be followed when stopping the compressor for maintenance or service: Step 1) WARNING ! Per OSHA regulation 1910.147: The Control of Hazardous Energy Source (Lockout/Tagout), disconnect and lockout the main power source. Display a sign in clear view at the main power switch stat ing that the compressor is being serviced. Never assume a compressor is safe to work on just because it is not operating.
•Drain receiver tank, drop legs and traps in air distribution system. •Give compressor an overall visual inspection and be sure safety guards are in place. •Check for any unusual noise or vibration. •Check lubricant pressure (hot). Maintain 18 to 20 PSIG*. •Check for lubricant leaks. •Check all pressurized components for rust, cracks or leaks. Immediately discontinue use of the equipment and relieve all system pressure if any of these problems are discovered.
Quin-Cip lubricant has proven under extensive testing to minimize friction and wear, limit lubricant carryover, and reduce carbon and varnish deposits. It will support the performance characteristics and life designed into all Quincy compressors and is highly recommended. Refer to the charts below to determine the correct amount of lubricant and viscosity to use for your model and application.

Pressure Switch Adjustment Pressure switches provided by Quincy Compressor are pre-set at the factory and usually do not require adjustment. However, the following procedures can be performed by a qualified electrician to adjust the pressure switch. Step 1) Remove the pressure switch cover. Step 2) While the compressor is running, screw the spring loaded adjustment screw in (clockwise) to increase the amount of air pressure required to open the switch and stop the unit.
Step 2) Rotate the oil pump housing 1/2 turn (180°). Note: The rotational arrow at the top of the pump housing should now reference the direction you wish the compressor to rotate. Make sure the forks of the bearing carrier driveshaft line up properly with the pin in the end of the crankshaft during reassembly. (See Fig. 5-4, Compressor Directional Arrows and Fig. 5-5, Driveshaft Alignment.
PILOT VALVE ADJUSTMENTS All adjustments made to the pilot valve must be performed by a qualified technician. The adjustments must be made while the unit is operating, therefore, extreme caution must be taken while working on the unit. Observe all necessary precautions. Always use a back-up wrench and make all differential and unload pres sure adjustments in very small increments (1/8 turn). WARNING ! The pressure switch and / or pilot valve are set at the factory for maximum efficiency.
