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.

Read the installation and operating instructions carefully.
Rotating machinery and pressurised components are potentially dangerous items of equipment if not operated and
maintained in the correct manner. It is imperative that all users of such equipment fully educate themselves as to
the potential dangers and satisfy themselves that those 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 user staff. If there are any doubts or ambiguities concerning
correct procedures, ask Utile Engineering, who will be pleased to advise, instruct or provide a service engineer. DO
NOT TAKE RISKS.
The following, whilst not exhaustive, provide guidance as to possible sources of danger to health and safety:-
Certain machinery can generate high levels of noise which can be harmful to people exposed to it for lengthy
periods of time. Various recommendations and 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.
Boosters, by their very nature, raise the pressure of a gas from one pressure level to another and 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 compressor installation with an inert gas, such as nitrogen. Special precautions are necessary for certain
gases and the user must ensure that adequate procedures are drawn up and implemented.
Moving parts of machinery must not be touched and must be adequately guarded. Suitable guards are provided
and must be securely retained in position at all times except when maintenance or service is being undertaken.
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.
NO attempt should be made to touch shafts, etc. whilst the machine is rotating. Particular care is needed when
checking clearances in machines and when inserting fingers through ports to check clearances, etc. Any movement
of may trap fingers
Most machines, casings and certain pipes and ancillaries become hot during. If it is possible for personnel to come
into contact with such surfaces unknowingly or accidentally they should be guarded.
If, during operation, severe vibration is observed on the booster, it's prime mover, pipework, or ancillaries, 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 debris is not allowed to enter the machine. Drainage systems must
also be serviced regularly to ensure that there is no liquid carryover.
Safety trips, emergency stopbuttons and other such devices 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.
During routine maintenance, coupling alignment should be checked to ensure that no damage would result from
excessive misalignment.
Only approved lubricants must be used and quantities, etc must be checked regularly.
After completion of servicing, all nuts, setscrews, etc must be checked for tightness
Before restarting after servicing, check all joints, etc are gas tight and carry out purging as necessary before
introducing the process gas. Also, before any start-up, check that the machine inlet and outlet isolating valves are
open and that the discharge non-return valve is the correct way round in the line.
Impellers on centrifugal compressors should be subject to periodic inspection to guard against undetected
corrosion or erosion that could lead to failure.

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. Do not use 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
Hammer / mallet Drill (low voltage)
Typical bolt tightening torques are: -

M8 18.00 Nm M24 250.00 Nm
M10 40.00 Nm ½” UNF 60.00 Nm
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. Where 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 - 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. 3).
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 ensure that no foreign matter enters the machine or serious damage may result.
An intake filter with diameter at least the same size as the compressor intake, 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 machine.
It is essential to fit a non-return valve in the pipework, preferably on the discharge 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 devices and switches these must be suitable for operation in the zone
classified.
All pipework and fittings must comply with IGE/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: -
9Ensure all the anchor bolts for the machine, base and motor are securely fastened.
9Check that the machine is free running by turning the shaft by hand through a few revolutions.
9Flick 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.
9Recheck coupling/drive alignment and retension (see page 6).
9Ensure all equipment is installed and earthed in accordance with current legislation.
9Check all piping connections.
9If 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.
9Check all protective devices ensuring they are working correctly.
9Ensure personnel are adequately protected from accidental contact with all dangerous equipment.
9Fill the constant level oiler with Shell Turbo T68 oil or equivalent (see lubrication).
9Instruct 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.
Inlet low-pressure switches are wired normally open and set no lower than 10mbar. Outlet high-pressure switches
are wired normally closed, adjust the switch in the same manner as the temperature switch and reset at working
pressure plus 10%. The pressure proving switch may be wired normally open or normally closed to make or break
your circuit, the set pressure should be just below actual operating pressure.
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 hours 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. Start the drive motor and bring the machine up to operating speed.
iii. Check all protective devices and controls making sure they are working correctly.
Operating Notes
Daily, check and fill the constant level oiler.
After initial running in, re-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 Dismantle)
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.

Fig 4
The design of the Constant Oiler prevents the flooding of the bearing
by the positive setting in the oiler, thus maintaining the correct level at
all times, this ideally is a third to half way up the bottom ball.
Tip the oil bottle back, and fill bottle through the stem (Fig. 4). Replace
bottle, and allow oil to flow into the reservoir. It may require the filling of
the bottle several times before the oil level in the reservoir is equal to
the level for which the oiler is adjusted.
NEVER FILL RESERVOIR THROUGH CAP
When the level is reached no more oil will run out of the bottle.The oil
bottle capacity is 115ml.
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 machines and
associated pipework have cooled down sufficiently before touching and attempting any maintenance.
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.
Typical bolt tightening torques can be seen on page 5. 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
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.
After maintenance the machine and equipment must be treated, as new and all pre-commissioning checks should
be made. Install all protective devices and controls properly after completion of work. Ensure all cabling, unions and
guards are correct, secure and in place. Dispose of any used oil and cleaning solutions as prescribed by law.
