Safety Precautions

Read this manual and follow all instructions prior to installing or operating the compressor.

This manual contains information required for safe, trouble free operation of the Quincy QSC5-DD rotary screw compressor. Damage incurred due to improper usage may not fall under the conditions of warranty.

For this reason, please keep this manual where all users have free access to it at all times.

The QSC5-DD was developed, manufactured, tested, and documented in state-of-the-art technology and considering all current safety standards.

Under normal circumstances, no danger for personnel or property will result if all stipulations of this manual are complied with and if the transport, assembly, service handling is performed according to the regulations.

Listed below are some, but not all, safety precautions that must be observed with compressors and compressed air systems.

Warning!

Failure to follow any of these precautions 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 OSHA 29 CFR �9�0.�34 or FDA2�XDE�78.3570 regulations.

• Disconnect and lockout all power supplies to the compressor plus any remote controllers prior to servicing the unit.

• Never assume it is safe to work on the compressor because it is not operating. Many installations have automatic start/stop controls and the compressor may start at any time.

• 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.

• Relieve all pressure internal to the compressor prior to servicing. Do not depend on check valves to hold system pressure.

• A properly sized pressure relief valve must be installed in the discharge piping ahead (upstream) of any shutoff valve (block valve), heat exchanger, orifice or any potential blockage point. Failure to install a pressure relief valve could result in the rupturing or explosion of some compressor component.

• 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. Over pressurization of system or compressor components can occur, resulting in death, severe personal injury or property damage.

• Never use plastic pipe, rubber hose, or soldered joints in any part of the compressed air system. Failure to ensure system compatibility with compressor piping is dangerous.

• Never use a flammable or toxic solvent for cleaning the air filter or any parts.

• Do not remove any guards or attempt to service any compressor part while the compressor is operating.

Section II - Description

• Proper Usage• Qualified Personnel• General Safety Instructions• Drive• Air Path• Fluid• Cooling• Flow Diagram

Proper Usage

The QSC5-DD is designed exclusively for the generation of compressed air and for operation in an environment without explosion risk.

Any other utilization is regarded as not in compliance with the design purpose.

The manufacturer/vendor is not liable for damage incurred if the QSC5-DD is not used according to its design purpose.

The generated compressed air may not be used for human respiration. If the compressed air is to be used for pharmaceutical or sanitary purposes, or in in production plants where it will come into direct contact with food, it must undergo further treatment.

Qualified Personnel

This manual is directed at qualified personnel who will transport, install, operate or service the QSC5-DD. Those individuals should read this entire manual, paying special attention to the section(s) relevant to their duties.

Qualified personnel are individuals who:

• upon the basis of their professional training, knowledge and experience as well as their understanding of the relevant norms can assess the work to be performed with regard to all possible dangers, or

• based on many years of activity in a comparable field, have the same state of knowledge as someone with professional training.

Activities not described in this manual must be performed by authorized technical personnel.

Warning!

Disregarding the warnings in this manual or those affixed to the compressor can lead to serious personal injury or property damage.



General Safety Instructions

Warning!

Retrofitting or modifications on the QSC5-DD may reduce its level of safety. The results could be serious personal, material or environmental damage. Retrofitting or modifications on the QSC5-DD with equipment components from third party manufacturers must first be approved by the manufacturer.

Danger!

Unless otherwise instructed, all installation, service or repair work must be performed on a switched-off, sufficiently cooled and pressure-free compressor. The compressor must be secured against being accidentally started during service. Follow all lock-out, tag-out procedures.

If measuring or testing work is required on the electrical components while the compressor is in operation, it must be performed by a licenced electrician observing all relevant safety regulations.

Caution!

Never direct compressed air streams towards persons. When working with compressed air, always wear protective safety glasses.

notiCe!

Use only factory spare parts and recommended fluids when servicing the QSC5-DD.

Quincy recommends keeping a set of service parts (parts subject to wear) on hand to ensure compressor availability. Contact Quincy customer service for assistance with ordering the correct parts.

Caution!

Damage to the compressor may result in environmental damage.

Before initial start-up, the compressor must be correctly installed according to Section III.

notiCe!

Dispose of all used or defective materials properly.

This is especially true for components/materials containing compressor fluid. Condensation containing fluid may not enter the sewage system.

Contact Quincy sales for an appropriate fluid/water separator for condensation processing.

notiCe!

Compressed air receivers require regular technical inspections.

Notify the responsible technical i n s p e c t i o n a u t h o r i t y o f t h e commissioning of the compressor. They will inspect the compressor and provide a receiver test book.



Drive

An electric drive motor drives the compressor through a flexible drop out type coupling.

compressor through the compressed air connection.

The inlet valve opens shortly after the compressor has started up for generating compressed air. It closes when the compressor changes to off-load operation and/or comes to a stop and unloads via the relief valve.

Fluid

Fluid is circulated through the airend and has the following functions:

• heat removal of the temperature increase caused by the compression process

• sealing lubrication of the rotors to each other and to the housing with a fluid film

• bearing lubrication

• noise dampening

Air Path

In the reservoir, compressed air is separated 98% from the fluid and the downstream air/fluid separator removes the remaining fluid from the compressed air. The air then flows via the minimum pressure check valve into the compressed air aftercooler and is cooled to �0 to �5°C (50 to 59°F) above the ambient temperature before it leaves the

Fluid leaves the airend with the compressed air as a hot fluid return air mixture. It is separated from the compressed air by an air/fluid separator in the separator tank. Once separated, it flows into the fluid cooler. A temperature regulator mixes the cooled fluid with the fluid cooler-bypass hot fluid as defined by the set point temperature. Finally, a fluid filter cleans the fluid before it is returned to the airend.

An additional heater can be installed in the separator tank, if desired, to prevent condensation damage in cold or damp compressor environments.

Cooling

The compressed air aftercooler is cooled by a built-in cooling fan.

The electric motor is always cooled by its own fan.

Section IV - Operating Procedures

• Prepare for Start-up• Check Fluid Level• Start-up Lubrication of the

Compressor• Switch on Compressed Air

Generation• Compressor Operation Checklist

Prepare for Start-up

�. Ensure that when the main compressor switch is switched off, no inadvertent switching on can occur.

2. Ensure that the compressor is correctly connected to the compressed air system and that when the shut-off valve on the pressure side is closed, inadvertent opening cannot occur.

Check Fluid Level

�. Ensure that escaping fluid can be collected.

2. Check the fluid level on the sight-glass (compressor fluid should completely fill the sight-glass). Loosen the filling screw. Do not lose the seal ring. With new compressors, the fluid level should be at the lower edge of the filler neck.

3. If required, top off fluid level (see Section V - Servicing, Check Fluid Level/Refill Fluid).

Start-up Lubrication of the Compressor

If the compressor is not operated for an extended period of time, i.e.: between delivery and start-up or during a company shutdown, there may no longer be any fluid in the rotor chamber of the airend. This fluid is absolutely necessary for bearing and rotor lubrication in the start-up phase.

�. Before switching on the compressor, add approximately 0.2 liter (6.76 oz.) of fluid at the filler screw of the inlet valve.

2. Rotate the airend by hand in the correct direction of rotation until the noticeable resistance dwindles and the fluid passes through the airend.

3. Finally, tighten the filler screw of the inlet valve.

If no extra fluid is available (only fluid of the same variety may be used), the fluid can be taken from the fluid drain.

If the compressor operates only very irregularly or is shut down weeks on end, it should run an hour in the off-load mode once a week in order to avoid corrosion damage caused by standing condensation.


Section IV - Operating Procedures

Switch on Compressed Air Generation

�. Before switching on the compressor, ensure that no one can be endangered by doing so.

2. Carefully open the shut-off valve between the compressed air connector and the system compressed air receiver. The compressor is now connected to the system.

3. Switch on the main switch.

4. Ensure that no tools or loose objects are lying on or in the compressor.

The line pressure will slowly rise if the compressed air consumption is less than the quantity delivered by the compressor.

Compressor Operation Checklist

Following start-up, perform the following checks to ensure that the compressor is operating properly:

�. Check all fluid and air piping for leaks.

2. Check the fluid level of the compressors at between �0 and 20 minutes of operation. If the fluid level is low, top off as defined in Section V - Servicing, Check Fluid Level/Fluid Refill.

3. Check the compressor temperature. The compressor temperature

should be between 75 and �00°C (�67 and 2�2°F); at �00°C (2�2°F) a warning is issued, at ��0°C (230°F) the compressor automatically shuts down.

4. Re-tighten all electrical connections after one week.

5. Perform service according to Section V - Servicing, Maintenance Schedule.

6. Check the standard operation of the functions performed weekly according to Section V - Servicing, Maintenance Schedule.

Check Fluid Level/Refill Fluid

Prepare the compressor for service as outlined above.

Check the fluid level when the compressor has been shut down for a minimum of 30 minutes to ensure that the fluid has settled after the running phase.

The fluid level is okay if the sightglass is full of fluid.

If the sightglass is not full of fluid, top off the fluid as follows:

�. Unscrew the fluid fill screw (retain the gasket ring).

Caution!

Mixing different types of compressor fluid can cause compressor damage. Compressor fluids must not be mixed. Use only original fluid.

2. Use an appropriate funnel for filling. Fill to the filling rim of the fitting.

3. Correctly seat the seal and screw the fitting screw closed.

4. Perform the steps under Completing Service (page �9) to put the compressor back into service.

Preparing for Service

�. Switch off compressed air generation. Wait until the compressor has been switched off after a run-on or ventilation phase.

2. Switch the main compressor switch off and perform lock-out tagout procedure to ensure that it cannot be turned on by mistake or intentionally.

notiCe!

Use Genuine Quincy replacement parts only.

Warning!

Hot surfaces, hot fluid. Ensure that no one can be burned or scalded. Particularly note dangerous situations which can arise from the release of hot fluid vapor.

3. Ensure that the pressure side shut-off valve is closed and cannot be opened accidentally or intentionally.

4. Verify that there is no pressure in the system.

5. Ensure that when working on the fluid circulation, escaping fluid is collected.



Check for Condensate

The absorption capacity of water humidity in the air falls with increasing pressure and rises with increasing temperature.

Sufficiently high compressor temperature guarantees that the intake air humidity does not precipitate as condensation. Frequent switching on and off of the compressor can result in the compressor not achieving the required operating temperature.

Caution!

Condensation in the compressor fluid can cause compressor damage. If you determine that there is condensation in the separator tank, contact Quincy service immediately.

Condensation damages are not covered by the warranty.

Since water is heavier than compressor fluid, after an extended shutdown (i.e.: over the weekend) the condensate collects in the bottom of the separator tank. It can be drained off by the discharge drain.

Perform the following service only when the compressor has been turned off at least overnight.

�. Prepare the compressor for service as outlined on page �5.

2. Open the drain and carefully observe the escaping liquid. Close the drain again as soon as fluid appears.

3. Check the fluid level as instructed on page �5.


Check for Leaks


2. Check all piping and the bottom of the compressor for fluid rests. If there is still fluid in the compressor, the cause should be found and the fluid removed.


Check the Compressor Temperature

The compressor temperature should be between 75°C and �00°C (�67 and 2�2°F).

Caution!

Too high or too low compressor temperature can cause compressor damage.



Check for Cooler Fouling


2. Check the fluid cooler and the aftercooler from the inside and outside. If you determine there is any fouling, it can be removed by

blowing it out using compressed air (the dirt particles should be blown outside).


Replace Fluid and Fluid Filter

Replace the fluid only when the old fluid is still warm. Cold fluid, because of its higher viscosity, does not flow as well.

Warning!

Hot surfaces, hot fluid. Ensure, that no one can be burned or scalded. Particularly note dangerous situations which can arise from the release of hot fluid steam.


2. Unscrew the filler screw (don’t misplace the gasket ring).

3. Open the fluid drain, allow the fluid to drain into an appropriate vessel and close the drain.

Caution!

Mixing different types of compressor fluid can cause compressor damage. Compressor fluids must not be mixed. Use only original fluid.

4. Use an appropriate funnel for filling. Fill to the filling rim of the fitting.

5. Verify that the seal is correctly seated and screw the fitting screw closed.

6. Loosen the fluid filter with a strap wrench and remove possible seal rests from the fluid filter housing.

7. Lightly oil the new fluid filter seal.

8. Screw the new fluid filter to the stop and tighten another half revolution by hand.

9. Test the fluid filter for leakage at operating temperature.

�0. Perform the steps under Completing Service (page �9) to put the compressor back into service.



Replace Air Filter


Caution!

The compressor must not be operated without an air filter. Dirt and dust entering the intake can cause damage to the compressor.

2. Remove the old air filter.

3. Install the new air filter.


Check Pressure Relief Valve


2. Remove the pressure relief valve and remove any residue at the threaded connection.

3. Check the pressure relief valve using an appropriate apparatus.

4. If it is still working correctly, add sealing tape to the connecting thread of the valve and reinstall it.

5. If the adequate functionality of the old pressure relief valves can no longer be guaranteed, install a new pressure relief valve.


Replace Air/Fluid Separator


2. Loosen the air/fluid separator using a strap wrench. Remove possible seal rests from the separator housing.

3. Lightly oil the new separator seal.

4. Screw the new air/fluid separator in to the stop. Tighten the separator another half revolution by hand.

5. Test the air/fluid separator for leakage at operating temperature.




Lubrication of the Electric Motor


2. The bearing lubrication period of 2000 hours for the electric motor must be observed.

3. Carry out the required lubrication with a grease gun.

Check Drive Coupling


2. Manually test to see if the coupling has radial play.

3. If so, loosen the cam ring of the coupling, push it back, and replace the coupling element.

4. Mount the cam ring on the coupling half and manually test for radial play again.


notiCe!

If there are no grease nipples on the electric motor, then it is equipped with capsulated permanently greased bearings. These motor bearings must be replaced when they are worn out.

4. Perform the steps under Completing Service on page �9 put the compressor back into service.

Completing Service

�. Open the stopcock slowly on the pressure side.

2. Switch the main compressor switch on.

3. Ensure that no tools or loose objects are lying on or in the system.

4. Check all fluid and air piping for leaks.

5. Check all new filter elements and newly mounted pressurized components for leaks at operating temperature.

6. Used filter elements, compressor fluid, seals, excess condensate and cleaning materials should be considered hazardous waste and disposed of in an environmentally friendly way.

notiCe!

Maintenance services not performed degrade the service life reliability of the system. Damages caused by improper usage or lack of maintenance are not covered by the warranty.
