General
The normal routine of running the machine is very simple. If it is carried out strictly at all times, many years of trouble free
service can be expected.
We emphasise two points of paramount importance-
1. Filtration of incoming air of gas 2. Lubrication
If possible provide a logbook so that the operator can enter daily readings. After several months a record will show whether
the machine is performing as it did originally. If readings are to be taken the following are all that is required. Inlet and
outlet air temperatures, suction conditions and oil drip rate.
A typical layout for the log book is shown in the table below.

Operating Principle
Rotary sliding vane compressors and vacuum pumps are multi-cell machines, which work on the displacement principle.
They provide a constant, low-pulsation supply of air or gas.
The machines have a cylindrical bored housing. The rotor, which is also cylindrical, is fitted eccentrically in the cylinder so
that a crescent-shaped working chamber is formed. Movable rotor vanes are fitted in the longitudinal grooves in the rotor;
centrifugal force and the force of the air or gas presses the blades against the cylinder-housing wall when the rotor turns.
The vanes divide the crescent-shaped working chamber into cells of different sizes. As the rotor turns, the cell volume on
the intake side increases, and the cell draws air in at low pressure, at which point is open to the intake delivery line. As the
rotor continues to turn, the cell is closed (see fig 1) and the volume of the cell decreases. This causes the enclosed air or
gas to be compressed (see fig 2) and forced out through discharge delivery line under atmospheric pressure.
The machine can only be run in one direction, which is indicated by an arrow on the cylinder. The direction of rotation must
not be reversed.

Read the installation and operating instructions carefully.
Rotating machinery and pressurised components, which may contain toxic, flammable or otherwise hazardous media are
potentially dangerous equipment if not operated and maintained correctly. It is imperative that all users of such equipment
fully educate themselves to the potential dangers and satisfy themselves that the personnel responsible for installing,
testing, commissioning, operating and maintaining the plant are competent to do so. Instruction manuals are provided for
guidance but must assume some basic level of competence by users. If there are any doubts or ambiguities concerning
correct procedures, ask Utile Engineering. DO NOT TAKE RISKS.
Certain machinery can generate high levels of noise which can be harmful if exposed to it for lengthy periods of time.
Various codes of practice are in existence and users must ensure that adequate precautions are taken to prevent a health
hazard to employees or third party.
Equipment with internal pressures above or below ambient pressures can create a hazard. Before attempting to investigate
problems, service or maintain equipment, it must be safely depressurised or pressurised to ambient conditions. Also since
the gaseous medium may be flammable, toxic, corrosive or otherwise hazardous it may be necessary to purge the
installation with an inert gas, such as nitrogen. Special precautions are necessary for certain gases and the user must
ensure that adequate procedures are implemented.
Moving parts of machinery must not be touched and all such parts must be adequately guarded. Suitable guards are
provided and must be securely retained in position at all times.
Before commencing maintenance, servicing or making other adjustments, the prime mover and other equipment must be
isolated electrically or otherwise immobilised to prevent accidental start-up. In this vein, a fully qualified electrician should
carry out all electrical work and all electrical equipment should be isolated before it is touched and pneumatic or hydraulic
controls depressurised and made safe. Procedures must also exist to ensure that electrical or other inputs cannot be
restored accidentally during the maintenance or service period.
Safety trips, emergency stop-buttons and other such devices (if fitted) are to be checked regularly to ensure that they
continue to function correctly and will protect the installation and personnel in the event of an emergency.
NO attempt should be made to touch the machine whilst it is rotating. Particular care is needed when checking rotor
clearances. Any movement of rotors may trap fingers.
Most machines, certain pipes and ancillaries become hot during operation whilst certain machines with sub-zero inlet
temperatures may result in very cold surfaces. If it is possible for personnel to come into contact with such surfaces
unknowingly or accidentally they should be guarded.
If severe vibration is observed, the cause of this should be immediately investigated and the situation rectified. Excessive
vibration can lead to fatigue and other failures. Similarly, if during operation a significant change is noticed in the level of
vibration, noise, temperature or any other parameter, the cause of such changes must be determined, and the cause
rectified. Inlet filters must be inspected regularly so that liquid or debris is not allowed to enter the machine, which could
cause damage and consequently injury to personnel.
During routine maintenance, coupling alignment should be checked for misalignment.
Only approved lubricants must be used and quantities, etc must be checked regularly.
Before restarting after servicing, all nuts, set screws, etc must be checked for tightness, check all joints, for leaks and carry
out purging as necessary before introducing the process gas. Also, before start-up, check the machine inlet and outlet
isolating valves are open both non-return valves (if fitted) are the correct orientation.
Adjacent pipework and equipment must not impose undue forces and moments on the machinery flanges.
All welding work must be carried out be an approved gas coded welder.
In order to prevent reverse rotation of machines, it is ESSENTIAL that a non-return valve be installed in the inlet pipework.
Otherwise a hazardous situation can arise during a normal shutdown or if the prime mover power supply is interrupted for a
period of time.
The environment around the installation may need to be monitored in order to detect gas leaks etc., and consideration
must be given to the installation of gas detecting equipment, and the class of electric equipment.
All personnel working in or passing through the area should be adequately warned by signs and trained to exercise
appropriate safety precautions. Ensure the correct personal protective equipment is worn at all times.

Note: Machine must not be used on any other gas than originally specified. Utile Engineering must be consulted if traces of
any other gas are introduced into the machine.
Packaging
The packaging conforms to the relevant regulations. The symbols used on the packages are
shown on the right. The machines are bolted down on a pallet and therefore should not
move during transportation and either cased or shrink wrapped for general protection. The
ancillary components are packed suitably within the case. The packaging and contents
should be received in good condition. When unpacking do not remove the inlet/outlet
protection covers.
The contents should be inspected against the advice note, notify Utile Engineering within 3
days of any items, which are damaged or are missing, followed by a written claim within
seven days of the goods being delivered.
Storage
If the machine is not required for immediate installation, the machine should be stored in a clean, dry area protected from
the weather. The intake and discharge port covers must remain in position until the machine is installed. We recommend
that the shaft be turned a few revolutions by hand to ensure the machine is running free every month until the machine is
installed.
The green protective coating on the shaft remains effective for approximately 1 year. If the machine is stored for a longer
period of time, the coat must be renewed.

Handling
Skilled personnel working in accordance with safe working practices must carry
out the lifting of machines. Before lifting the correct equipment must be
available. Cranes, jacks, slings, and lifting beams must be capable of carrying
the weight of the machine to be lifted. The lifting eyebolt situated in the top of
the cylinder and a crane hook must be used when lifting or moving the
machine (see fig 3). Do not use the machine ports or the shaft extension for
lifting or moving the machine.
For weights see above in Technical Specification.
Installation
Before commencing installation, a site specific risk assessment, method statement and hazard identification list must be
completed and adhered to. All work must be carried out in a safe area. Utile Engineering trained personnel or those trained
to an equivalent standard should carry out installation, any claims for damage due to faulty installation will be void. The
machine is delivered ready to be connected, with only the removal of the intake and discharge protection covers. All
warning labels and instructions must be observed and retained with the machine. Before installation, ensure there is no
damage to the machine and that it turns freely by hand.
Typical tools required for installation include: -
Set of spanners Pipe Wrenches Set of screwdrivers Hacksaw

Location
The machine should be installed in a clean, dry, well-ventilated area. Allow adequate space and facilities for service,
inspection and future expansion. A minimum of 0.75m of working space around the machine is recommended. Adequate
space around the motor and machine, particularly any fan inlets, is also necessary to facilitate cooling airflow. If several
machines are installed in close proximity, care must be taken to ensure there is no recirculation of exhausted warm air.
Foundation
Simple slab type foundations, designed for static loadings only are satisfactory. The foundations should raise the machine to
a reasonable height above the floor for convenient service and inspection. The use of anti-vibration mounts between the
base and foundation are recommended, these absorb the vibrations generated by the rotating parts of the machine and
insulate it against any vibration in the surrounding environment. Ensure that the anti-vibration mounts are evenly loaded.
Foundation bolts should fix the base.
Electrical Supply and Connection
The voltage rating of the supply must be compatible with the motor and the fittings. All electrical installation must be
carried out by a qualified electrician and in accordance with current regulations and within the framework of the Electricity
of Work Regulation 1990. Ensure all electrical connections, plugs, sockets etc are secure before switching the supply on.
Earthing
It is important that the motor enclosure is soundly earthed by metallic earth continuity conductor, or by separate earth
bonding, but in all cases the installation must be made and tested and approved for this feature by a qualified installer
before the supply is applied to the motor.

Fitting Pulleys and Couplings
These should be bored to our standard limits (details supplied upon request) and fitted to the shaft with a screwing motion.
On no account should they be driven on. Tapping of fitments onto the machine shaft with a hammer or mallet, causes
bearing damage. This results in an increase in bearing noise and a significant reduction in bearing life. Attention should be
paid to the guarding of all moving parts.
Drive Alignment
The rotor shaft must always be horizontal. There are three basis modes of misalignment, these are angular, parallel and
axial (shown in fig. 4).
Flexible Coupling
1. Remove any dirt, oil, etc. from all mating surfaces. Place bush in hub and match
half holes on both shafts.
2. Place setscrews loosely in threaded holes. Mount assembly in desired position on
shafts.
3. Tighten setscrews. Place disc/flexible coupling in position, and bring the shafts
together obtaining the manufacturers assembled length for the coupling given in
their instructions.
4. To check for angular alignment: (see fig. 5)
Rotate the coupling through 90°and measure the distance between the faces.
Repeat adjusting the shafts until four identical measurements are obtained.
To check for parallel alignment: (see fig. 5)
Place a straight edge across the coupling. The hubs will be in correct alignment
when the straight edge contacts the 4 points squarely.
Drive Belts
1. Remove any dirt, oil, etc. from all mating surfaces. Place bush in hub and match
half holes on both shafts.
2. Mount assembly in desired position on shafts ensuring both shafts are parallel and
in correct alignment, use a straight edge, a correctly aligned drive will contact both
pulleys squarely (see fig. 6).
3. Fit driving belts. Measure span of belts between
tangent points of the two pulleys. A deflection of
1.5mm is obtained for every 100mm of the
measured span. Compare the deflection force
required with the table. If the force required is
according to the table then the tension is suitable.
Too little force indicates under-tension and visa-
versa.
4. The belts should be tensioned towards the high side, to allow for the tension drop
after the belts have been run-in. Belt tension should be checked daily in the first
week after installation/renewal.
Warning:
Excessive tension on the pulleys will damage the bearings and lead to a probable shaft rupture.
Belts, which become charged electrostatically, must not be used in hazardous atmospheres.

Pipework
The connecting pipework must be completely clean, dry and free from internal rust or scale.
When fitting the intake and discharge pipework it is essential that adequate supports be provided and that it is properly
aligned to prevent excessive strain being placed upon the machine, flexible pipe should be placed in the pipeline to
remove this strain.
During installation care must be taken to ensure that no foreign matter enters the machine or serious damage may
result.
An intake filter should be fitted into the intake side to prevent any particles from entering the machine.
Use P.T.F.E. tape only as a jointing medium since surplus from jointing compounds will damage the blades if drawn
into the machine.
When the machine is delivering into or exhausting from a receiver, or working with a system having a large storage
capacity, it is essential to fit a non-return valve in the pipework, preferably on the intake side to prevent the machine
from running in reverse on shutdown.
Arrange both the intake and discharge pipework so that any condensate flows away from the machine.
If user is installing their own protective switches and other devices these must be suitable for operation in the zone
classified.
All pipework and fittings must comply with IGEM/UP/2 or the national standard for the country of installation.
Pre Start-up Checks
Before starting the machine for the first time after installation, maintenance or after a long downtime, make the following
checks: -
Ensure all the anchor bolts for the machine, base and motor are securely fastened.
Check that the machine is free running by turning the shaft by hand through a few revolutions.
Flick start the motor to check that the direction of rotation agrees with the arrow on top of the machine cylinder. Note
this should be completed with the coupling/drive belts removed.
Recheck coupling/drive alignment and retension (see page 7).
Ensure all equipment is installed and earthed in accordance with current legislation.
Check all piping connections.
If the system is to be pressure tested, all gauges and pressure switches must be isolated or removed. Maximum purge
or pressure test is 1.50 times the working pressure.
Check all protective devices ensuring they are working correctly.
Ensure personnel are adequately protected from accidental contact with all dangerous equipment.
Fill the oil tank with Shell Turbo T68 oil or equivalent (see lubrication), prime the oil lines to the machine.
Instruct the operating personnel that the machine is operational.
Protective Devices
All pressure and temperature switches must be set and tested at the desired set point by simulating the set point in actual
operation.
With the machine running at the duty pressure after warming up, adjust the discharge temperature switch downwards to
actuate and stop the machine. Reset the switch at the cut out temperature plus 10C - 15C in order to avoid false tripping
from small and reasonable increases above normal levels.
Adjust the high pressure cut out switch in the same manner and reset at working pressure plus 10%.
After the first 50 running hours, remove the cone shaped mesh strainer from the inlet, clean and replace. If a large amount
of debris has been collected run for a further 50 hour period repeating the process until the filter remains clean.
Start-up
Proceed as follows: -
i. When starting compressors the intake valves are fully open. Compressors can usually be started against normal
discharge pressure.
ii. Some compressors are piped with a manual start-up bypass valve from discharge to intake, for pressure equalisation
during startup, This must be fully opened before startup.
iii. Start the drive motor and bring the machine up to operating speed.
iv. When full speed is reached slowly close the manual start-up bypass valve.
v. Check and adjust the lubricator drip rate to that indicated in the lubrication section.
vi. Check all protective devices and controls making sure they are working correctly.

Operating Notes
Daily, check the oil drip rate through the indicator. Fill the oil tank.
After the initial running in period, check the belt tension. Belt squeal denotes a loose belt that requires tightening.
Inspect the filter fitted to the inlet, regularly clean and renew the element when necessary.
Excessive discharge temperature for normal operation as indicated by the rise in temperature shown in the log book
indicates inadequate cooling, faulty lubrication or a dirty intake filter. The machine should be stopped and inspected.
Check the machine internally for wear every 10,000 running hours. (see Inspection and Service)
The blade depth should be checked after the initial 2,000 running hours and thereafter every 5,000 running hours for
wear and renew if the rubbing tips have worn to a depth of 67mm. (see Check Blade Wear).
Condensate if allowed to enter the machine can cause severe blade wear.
If adjustment of the oil drip rate is required (see lubrication).
If machine is on a standby service, run for a few minutes each week.
Stopping Procedure
Proceed as follows: -
i. Trip out or Stop the drive motor.
Lubrication
Prime oil pipes prior to initial start and every time machine is
dismantled for service, as serious damage will occur if the
machine runs unlubricated. The lubrication system is a total
loss system, recycling of oil is not recommended
The recommended grade of oil is Shell Turbo T68 the typical
physical characteristics are shown above.
Oil feed rate per calibrated oil drip measuring device is shown
on the right. These are available from our spares department.
The feed rates can be increased/decreased pro-rata with
speed.
Oil pump adjustment
The pump is adjusted to the correct flow rate when despatched from our works. If it
found necessary to alter the oil feed, then proceed as follows using fig. 7:
1. Remove the cover (1) to expose two pistons (2).
2. Slacken off the locknuts (3) and adjust the feed as required.
To increase the flow, turn the two adjusting screws (4) clockwise, or anti-clockwise to
decrease.
Lubricator Maintenance
Refill the oil reservoir regularly to ensure that the oil level is not allowed to fall to a
point where air can be drawn into the oil pump. Use only clean, new oil of the
recommended grade. At least once a year, or if the machine has been out of use for a
long period, the oil pump must be thoroughly flushed out with petrol/kerosene to clear any oil residues that may have
solidified in the control ducts. For this operation we recommend the following procedure: -
1. Stop the machine and disconnect all the oil pipes from the oil pump.
2. Remove oil reservoir, drain oil and wash out with petrol/kerosene. Drain again ensuring all oil residues are
removed. Replace reservoir and reconnect the oil feed pipe (oil reservoir to oil pump).
3. Fill the reservoir with petrol/kerosene to cover oil filter element. Loosen oil feed pipe connection at oil pump end
until all air has been expelled. Re-tighten pipe.
4. Start the machine under no load condition and run until petrol/kerosene begins to flow from oil pump discharge
points. This operation takes approximately 10 –15 minutes and providing the machine is run under no load
conditions, no damage will occur.
5. Stop machine, drain oil reservoir and fill with recommended grade of oil. Ensure all oil pipes are primed. Reconnect
oil delivery pipes (oil pump to machine) and start up.

Maintenance
Fully trained and competent staff must carry out any maintenance work. Utile Engineering offers contract maintenance
services if required contact our service department.
When carrying out any maintenance and inspections always follow the health and safety guidelines on page 4.
A regular correct maintenance plan is essential to good operational reliability and a long service life for your machine. As
operating conditions vary, no exact timings can be specified for wear checks, repairs and inspections, however the following
plan can be used as a guide until time scales to better suit the machines environment are found.
The machine, ancillaries and surrounding area should be kept as clean as possible.
Ensure all items are properly held and supported during all aspects of maintenance as not to pose a problem for health and
safety. Observe all lifting points and apply care when handling the equipment.
Ensure all machines and associated pipework have cooled down sufficiently before touching and attempting any
maintenance.
Typical tools required for maintenance include: -
Set of spanners Pipe Wrenches Circlip Pliers
Set of screwdrivers Vernier Gauge / Micrometer Two-leg Pulley drawer
Set of Allen Keys Hammer / mallet Feeler Gauges
Typical bolt tightening torques can be seen on page 6.
New gaskets must be fitted every time the machine is dismantled.
Bearings and seals are recommended to be replaced after 15000 operating hours or 2 years whichever is sooner.
Blades must be replaced regardless of wear after 20000 operating hours as failure due to fatigue could cause serious

2. Blade Inspection
When carrying out any maintenance and inspections always follow the health and safety guidelines on page 4. Ensure all
electric circuits are isolated and cannot be switched on, and that the pipeline system has been cleared and is pressurised to
atmospheric pressure. Fully trained and competent service personnel must carry out any maintenance work.
Inspection commences with the dismantling of the rear end, after removal of the oil tank and pipes.
2.1 Remove three screws (32) and remove fancowl (11) loosen the set screw in fan and remove fan (10).
2.2 Undo four screws (31) and take off end cap (5) complete with mechanical seal seat (20). Inspect the faces of the
mechanical seal for wear and replace complete seal if either are worn. Remove the mechanical seal (20) taking
care not to damage the carbon face. If the seal is stuck on the shaft, carefully prise free with a screwdriver
between the locating ring and the locknut (28).
2.3 Remove the locknut (28). Do not loose the bearing flange.
2.4 Remove six bolts (30) and withdraw coverplate (3) complete with outer race of bearing (23) and seal (21).
2.5 Measure and note the thickness of the gasket (49) fitted between the cylinder (1) and coverplate (3).
2.6 The blades (7) can now be removed form their slots for inspection.
Check the blades for lamination, chipping or charring on their rubbing edges and for concave wear. For any other
wear other than polished surfaces or if the blade depth has reduced to 67mm or below then replace the blades.
When replacing blades a complete set must be replaced. The old blades must be disposed of according to the local
government laws. When fitting new blades, ensure they slide freely in their slots and if necessary remove high
spots with fine emery cloth. Lightly smear blade surfaces with oil before reassembly.
2.7 Inspect the visible part of the cylinder bore and rotor for any signs of excessive wear or scuffing and for excessive
slot wear. If there is any sign of cylinder rubbing completely dismantle the machine. Factory reconditioning is
recommended, but if work has to be carried out on site, we advise you most strongly to contact Utile Engineering
Service Department for advice.
During inspection, determine if the correct oil is being used. Bearings, cylinder wall, rotor/shaft assembly and
blades should show a polished surface with a light film of oil. Hard baked deposits indicate inferior oil, dirt or
excessive temperature.
3. Reassembly after Blade Inspection
Reassemble in the reverse order, taking note of the following points: -
3.1 Ensure the blades are orientated correctly in their slots.
3.2 If coverplate gaskets have been replaced, it is essential that they are the same thickness as the originals,
otherwise internal clearances will be affected and could cause serious damage. Lightly smear the gasket with oil
before replacing.
3.3 Replace coverplate assembly, screws, locknut and tab washer, mechanical seal, end cap, fan and fancowl. Before
reconnecting oil pipes ensure they are primed.
4. Cylinder Renewal
With the rear end coverplate (3) already removed as described in 2 for blade inspection, the next stage is to withdraw the
rotor complete with the drive end coverplate (2).
4.1 Take off timing belt (51), drive pulley (48). Slacken clamp screw (34) in support plate (12) and remove complete
with oil pump assembly.
4.2 Undo four screws (31) and take off end cap (4) complete with mechanical seal seat (20). Inspect the faces of the
mechanical seal for wear and replace complete seal if either are worn. Remove the mechanical seal (20) taking
care not to damage the carbon face. If the seal is stuck on the shaft, carefully prise free with a screwdriver
between the locating ring and the locknut (28).
4.3 Remove the locknut (28).
4.4 Remove six bolts (30) and withdraw coverplate assembly (2) complete with rotor assembly. Measure and note the
thickness of the gasket (44) fitted between the cylinder (1) and coverplate (2). The cylinder can now be replaced
or rebored.
4.5 When reboring the cylinder the maximum allowable increase in diameter is 0.8mm to give a final bore of
185.00mm. Contact Utile Engineering for appropriate assembly instructions in this case.

6. Reassembly Procedure
This section only applies when using original bore size or replacement cylinder. Before commencing reassembly ensure that
all components are perfectly clean and oilways are clear. Lightly smear the shaft with oil to assist assembly.
The correct clearances for these machines are: -
L95HP
L130HP
L175HP
Drive End Coverplate / Rotor
0.25mm / 0.30mm
0.25mm / 0.30mm
0.25mm / 0.30mm
Rear End Coverplate / Rotor
0.10mm / 0.13mm
0.10mm / 0.13mm
0.10mm / 0.13mm
Rotor / Cylinder
0.10mm
0.10mm
0.10mm
Reassembly should start with the preparing of the rotor and shaft assembly by the fitting of the replacement seal sleeve (if
required) and the inner races of the both roller bearings.
6.1 The seal sleeve (9) are retained on the clean shaft using LOCTITE 648 adhesive or equivalent, and should be
pushed hard against the rotor face. It is essential that the width of the seal sleeve is identical to the one it is
replacing or internal clearances may be effected causing serious machine damage.
6.2 Both roller bearing inner races can now be fitted onto the shaft ensuring the bearings and any shims are fitted to
the correct ends.
Starting at the drive end
6.3 Position the bearing seal (21) into position in the coverplate (2) ensuring that the tension spring is facing the rotor.
6.4 Press the outer race of roller bearing (22) into position in the coverplate (2).
6.5 Lay the rotor/shaft assembly on the bottom of the cylinder (1), ensure the cylinder is orientated correctly.
6.6 Ease coverplate (2) onto the rotor/shaft.
6.7 The whole bearing assembly can be locked onto the shaft with the locknut (28). Set clearance.
6.8 When fitting the mechanical seal (20), wipe over the shaft with soapy water to assist the assembly, the seal can
then be eased onto the shaft and pushed against the locknut. Replacement seal seats should be lubricated for
easier fitting in the end cap.
6.9 The end cap (3) can now be fitted with the gasket (45) and any appropriate shims.
6.10 Fit new o-rings (24) into the coverplate grooves. If coverplate gasket (45) has been replaced, it is essential that
they are the same thickness as the originals, otherwise internal clearances will be affected and could cause serious
damage. Lightly smear the gasket with oil before replacing.
6.11 Place drive coverplate assembly onto cylinder (1) via location dowel and bolt with six screws (30) and with
coverplate gaskets (45) in place.
6.12 Check rotor / cylinder clearance.
