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 every

Quincy compressor. It is the intention of this manual to pass along the “safety

ﬁrst “ concept to you by providing safety precautions throughout its pages.

“WARNING !”, “CAUTION !”, and “DANGER !” are displayed in large

bold capital letters in the left hand column to call attention to areas of vital

concern. They represent different degrees of hazard seriousness, as stated

below. The safety precaution is spelled out in bold upper and lower case letters

in the right hand column.

Immediate hazards which will result in severe personal injury or

death.

Hazards or unsafe practices that could result in personal injury or

death.

Hazards or unsafe practices which could result in minor personal

injury, product or property damage.

Each section of this instruction manual,as well as any instructions supplied

by manufacturers of supporting equipment, should be read and understood

prior to starting the compressor. If there are any questions regarding any part

of the instructions, please call your local Quincy distributor, or the Quincy

Compressor factory before creating a potentially hazardous situation. Life,

limb, or equipment could be saved with a simple phone call.

Compressors are precision high speed mechanical equipment requiring

caution in operation to minimize hazard to property and personnel. There

are many obvious safety rules that must be observed in the operation of this

type of equipment. Listed below are some additional safety precautions that

must be observed.

•Transfer of toxic,dangerous, ﬂammable or explosive substances using Quincy

Compressor products is at the user’s risk.

•All installation, maintenance and repair must be performed by a qualiﬁed

technician and / or electrician.

•Turn off and lockout/tagout (per OSHA regulation 1910.147) the main power

disconnect switch before attempting to work or perform any maintenance.

•Do not attempt to service any part of the unit while it is running.

•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.

•Allow ample time for the compressor to cool before performing service pro-

cedures. Some surface temperatures exceed 350°F when the compressor is

operating.

•Do not remove or paint over any DANGER!, WARNING!, CAUTION!, or

instructional materials attached to the compressor. Lack of information re-

garding hazardous conditions can cause property damage or personal injury.

•Periodically check all pressure relief valves for proper operation.

•Do not change the pressure setting of the pressure relief valve, restrict the

function of the pressure relief valve, or replace the pressure relief valve with

a plug.

•Do not install a shutoff valve in the compressor discharge line without ﬁrst

installing a pressure relief valve of proper size and design between the shutoff

valve and the compressor.

•All components of the compressed air system must be properly rated for the

application.

•Alterations must not be made to this compressor without Quincy Compres-

sor’s approval.

•Be sure that all tools, shipping and installation debris have been removed

from the compressor and installation site prior to starting the compressor.

•Do not operate the compressor in excess of the ASME pressure vessel rating

for the receiver or the service rating of the compressor, whichever is lower.

•Make a general overall inspection of the unit daily and correct any unsafe

situations. All fasteners and ﬁttings must be kept tight.

•Reckless behavior of any kind involving compressed air is dangerous and

can cause very serious injury to the participants.

•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.

•Wear safety glasses and hearing protection during operation, service and

maintenance procedures.

Air used for breathing or food processing must meet OSHA 29 CFR

1910.134 or FDA 21 CFR 178.3570 regulations. Failure to do so may

cause severe injury or death.

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 compres-

sion, causing an explosion, damage to property and injury to per-

sonnel.

SYSTEM DYNAMICS

•Principles of Compression Cycles

Single Stage Compressors

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 bot-

tom 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.

Total compression, from atmospheric pressure to the ﬁnal discharge pressure,

is accomplished in one stroke of the piston.

Two Stage Compressors

During the downstroke of the piston of a two stage compressor, air is drawn

through an intake valve in the head of the compressor and into the low pres-

sure cylinder. This air is 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 (usually ﬁnned tubing) 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 or directly to a network of compressed air supply lines. In

one revolution of the crankshaft a compression cycle is completed.

•Principles of Lubrication System

Splash Lubricated Models

With each stroke of the compressor, a dipper attached to the bottom of the

connecting rod, dips into a lubricant bath at the bottom of the crankcase. This

dipper causes the lubricant to splash throughout the interior of the crankcase,

lubricating all moving parts.

It is important with this system that the lubricant level be maintained

between the high and low level marks on the dipstick. If the lubricant level

is too high, excessive lubricant carryover could result. If the lubricant level is

too low, or the compressor is not operated within the correct RPM range, the

moving parts will not be adequately lubricated.

Pressure Lubricated Models

Moving parts within the crankcase are lubricated by means of a positive

displacement, gerotor type oil pump. Lubricant is drawn up from the bottom

of the crankcase to the oil pump through an oil sump strainer screen. The

lubricant is then forced under pressure through the oil ﬁlter (if so equipped).

Lubricant travels under pressure through drilled journals in the crankshaft

and connecting rods to lubricate crankshaft bearings, wrist pin bearings and

the cylinder walls.

•Principles of Cooling System

Fan blades in the compressor sheave force ambient air across ﬁns on the cylin-

der heads (and intercooler ﬁns of two stage compressors). Quincy compressors

should be operated in temperatures under 104°F.

Principles of Dryers & Filters

Moisture occurs naturally in air lines as a result of compression. Moisture

vapor in ambient air is concentrated when pressurized and condenses when

cooled in downstream air piping. Compressed air dryers reduce the moisture

vapor concentration and prevent water formation in compressed air lines.

Dryers are a recommended companion to ﬁlters, aftercoolers, and automatic

drains for improving the productivity of compressed air systems.

Water and moisture vapor removal increases the efﬁciency of air operated

equipment, reduces contamination and rusting, increases the service life of

pneumatic equipment and tools, prevents air line freeze-ups, and reduces

product rejects.

•Principles of Control System

Simplex Units

Simplex Climate Control units are controlled by a pressure switch which

detects the demand for compressed air and allows the motor to start. When

the demand is satisﬁed, the unit stops.

Duplex Units

Duplex Climate Control units are controlled by multiple pressure switches

(one for each compressor). They react to a demand for air the same way as a

simplex unit. In addition to the pressure switches, duplex units can be con-

trolled by an electrical alternating switch that automatically distributes the

workload evenly between the two basic compressors. The following example

best explains the process:

The lead compressor starts and runs to satisfy the air demand. When the

pressure in the system reaches the cut-out pressure of the lead compressor, it

shuts off. The next time air is required, the lag compressor starts up ﬁrst and

becomes the lead compressor.

If the lead compressor can not satisfy the air demand, the lag compressor

will automatically start and assist until the pressure in the system reaches

the cut-out pressure. At the cut-out pressure, both the lead compressor and

lag compressor shut down. The cut-in pressure of the lead pressure switch is

normally set 10 PSIG higher than the lag pressure switch.

SECTION 3 INSTALLATION

•Receiving Delivery

Immediately upon receipt of compressor equipment and prior to completely

uncrating, the following steps should be taken:

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 Com-

pressor warranty.

Step 2) Insure that adequate lifting equipment is available for moving

the compressor equipment.

Improper lifting can result in component or system damage, or

personal injury. Follow good shop practices and safety procedures

when moving the unit.

Step 3) Read the compressor nameplate to verify the model and size or-

dered.

Step 4) Read the motor nameplate to verify that the volt, phase and hertz

ratings are the same as the electrical power supply connecting to

the motor. NOTE: Do not use a triple voltage (115/208-230)

single-phase motor or (208-230/460) 3-phase motor for 208

volts or lower. Use a 200 volt or 208 volt motor only.

Step 5) Read the pressure relief valve nameplate to be sure it does not

exceed the working pressure shown on the compressor or any other

component in the system.

Step 6) Read and understand the safety precautions contained

within this manual. The successful and efﬁcient operation of

compressor equipment depends largely upon the amount of care

taken to install and maintain the equipment. Quincy Compressor

strongly recommends that any or all person(s) in charge of install-

ing, maintaining, or servicing one of our compressors read and

understand the entire contents of this manual in order to perform

such duties safely and efﬁciently.

•Freight Damage

It is extremely important that you examine every carton and crate as soon as

you receive it. If there is any obvious damage to the shipping container, have

the delivering carrier sign the freight bill, noting the apparent damage, and

request a damage report.

If concealed damage is discovered at a later date, the carrier must

be notiﬁed within 15 days of initial receipt of freight. Concealed ship-

ping damage is not covered by Quincy Compressor. Contact the carrier as

soon as possible, giving them an opportunity to inspect the shipment at the

premises where the delivery was made. Do not move the damaged freight from
