1.10 SUGGESTIONS
9 After repair, maintenance and adjustment works make sure that there is not any spare part,
cleaning material or hand tool are left inside.
9 Make sure that all the guards are installed after repair, maintenance or adjustment works.
9 Make sure that none of the moving parts are in contact with any component.
9 Do not leave unplugged electric conducting cables.
9 If the compressor will not be used for a long time; it should be stored at dry and warm
environment. The oil in the oil tank should be discharged and the screw unit has to be
lubricated with a protective lubricant against corrosion. If the compressor have belt driving the
belts must be removed or completely loosened.
1.11 AIR RECEIVER

2. CHAPTER
INSTALLATION & ASSEMBLY
2.1 INSTALLATION OF THE COMPRESSOR AND CONNECTIONS
9 The floor on which the compressor is mounted should be capable of carrying the weight of
compressor and should be flat and dry. There is no need to fixing (anchorage bolt etc) to the
floor.
9 The compressor room should be easily accessible and sufficiently illuminated.
9 For adequate service, the compressor room should have a clearance of at least 1.5 m from
ceiling and 1m from the wall.
9 Fire and corrosion causing conditions should be prevented in the operation region.
9 No pipe load (swaggering connections or tensions arise from environmental variations) should
be relayed to compressor by external connections.
9 Make sure that the air supply equipment is suitable to the operating pressure of the piping and
fittings and is damage free.
9 Select the diameter of the air supply, dryer and line filters according to your air supply
capacity. (It is beneficiary to select piping of big diameter considering future development of
your company).
9 Establish a separate line for condense discharge of your filter and dryer and air tanks (water
discharge line); this way the floor of the compressor operating place does not unnecessarily
get wet.
9 Put an air exit and electric box in your compressor room for general purpose
9 Your compressor is manufactured for indoor operation.
9 In case of different needs in relation to compressor or air supply contact service or sale
representative.
2.2 COMPRESSOR ROOM VENTILATION
9 In order to maintain the operation temperature at a specific value, place your compressor at a
place that adequate air flow is provided. The temperature that compressor operates should be
at least 2 and at most 40 °C. Do not place your compressor where the temperature is less
than + 2 °C and if necessary heat the compressor room.
9 If you think that there will not be sufficient amount of air flow in the room of operation; it is
necessary to make room ventilation or you must discharge the outgoing hot air the
compressor to outside. When doing this, the outgoing hot air of compressor shoul d not return.
For this reason the hot air outlet and room air inlet should not be on the same side. If
necessary use a fan for discharging the hot air from the room. Place this fan to the closest
point of the compressor hot air outlet
9 Avoid not expose the compressor cooler to direct sun light or regional strong winds.
9 Avoid the compressor room being subjected to heat or dust emitted by central heating boiler
or generator type of equipment.
2.3 ELECTRICAL CONNECTIONS
9 Ensure that the electrical installation of your compressor is performed by a qualified
electrician.
9 Your compressor is designed to operate with three phase system. The voltage and frequency
data are written on the template of your compressor and in the “Technical data” part of this
handbook. Suitable cross sections for supply cable selection are shown in “3.2 Energy cable
dimension “section.
9 Your compressor is designed to operate in + 2 to + 40 °C ambient temperature and at most
1000 meters above the sea level. At higher altitudes, some corrections must be made by
taking into account of environmental conditions. The data related with this is shown in detail at
the maintenance “motor maintenance” section 5 of this handbook.
9 Attach the grounding cable to the outer side of compressor with a screw marked with .
Ensure that the grounding line operates properly.
Working without grounding may be dangerous for the work safety of the personnel
and compressor. In case of failure and critical situation, please properly install your
grounding line in order to prevent death

OPERATION
4.1 GENERAL
In order to enable you to easily see the operation and adjustment values of the compressor, an
electronic controller unit is installed to the system. The electrical and mechanical precautions have
been taken for establishing of operational safety. Some of the equipments of the compressor are
described below for your information.
4.2 FUNCTION EXPLANATIONS
CONTROL UNIT : See chapter 7 (Control Unit) for detailed information
COMPRESSOR UNIT : This is the part which produces air. Rotated by motor
MOTOR : Supplies mechanical drive for airend unit
INTAKE VALVE : Controls the air suction and provides machine run on load or unload
CONTROL SOLENOID VALVE : When the compressor reaches to adjusted pressure values, it
controls the air that goes to intake valve and makes the compressor operate at unload.
PRESSURE SWITCH : If the pressure in air vessel exceeds the set value, the pressure switch
stops the compressor. It is placed on the left side of electric board.
SAFETY VALVE: When the pressure in tank increased very high in case
of
failure, it releases the pressure and establishes safety.
MINIMUM PRESSURE VALVE : It provides the pressure remain at 4
bars in the oil receiver. In addition in case of idle operation and switching
of compressor; it prevents the system pressure to penetrate back to the
oil receiver.
COOLER : Cools the oil in the system and produced air.

9 The electric motor of compressor (1) rotates airend unit (2).
9 Airend unit absorbs the air passing from pilot intake section of the intake valve (3) and sends it
to separator tank (5) after mixing with oil. This way pressure inside separator tank (internal
pressure) starts to rise.
9 When the internal pressure comes to a reasonable level suction valve fully opens and
compressor is loaded (20).
9 Minimum pressure valve (7) does not send the internal pressure to use until it becomes to 3-4
bar, keeps inside separator tank.
9 When internal pressure starts to exceed 3,5-4 bars, minimum pressure valve can not
overcome the internal pressure and air production is started by opening the way.
9 Separator filter (6) atop of the separator tank separates the compressed oil/air mixture from
each other.
9 The separated air passes through minimum pressure valve and comes to the after cooler side
of combicooler (11).
9 The oil inside the separator tank comes to the thermal valve by the effect of internal pressure.
Thermal valve (17) does not let the oil to flow through the cooler until the oil temperature
reaches the specific value. In this case; oil goes from separator tank directly to oil filter (9) and
from there to airend unit. When the oil temperature reaches the required value (71-85 °C);
thermal valve closes the line in between separator tank and oil filter. And it ensures the oil to
flow into cooler side of combicooler (8). After cooling process, oil sent to oil filter, then, the
filtered oil is again sent to screw oil inlet and lubrication cycle continues.
9 The fan on the compressor (18) ensures the flow of cooling air absorbed from environment to
cooler. The cooler is composed of two parts; one for air and one for oil. This way oil and air
are separately cooled in respective sections.
9 The air absorbed by compressor is filtered twice. When the fan sends the cooling air into
compressor, the absorbed air is cleaned by air panel filter (19). The air absorbed by airend is
filtered again while passing through intake filter (4)
9 Small quantity of oil leaks into separator filter during operation. This leakage is sent back to
system by oil return line (scavenge) (10).
9 In order for establishing pressure safety inside separator tank, safety valve (14) provides
safety for future failure situations.
9 The oil is supplied in the compressor by removing the oil tap (15) on compressor chassis. The
old oil is discharged by discharge valve (16) under separator tank.

4.4 START-UP
9 Before start up the compressor, check the electrical and air line connections.
9 Check that the compressor’s cooling air inlets and outlets are not closed. Do not cover your
compressor with cloth, nylon etc. Do not operate if covered.
9 Inside electrical panel of your compressor there is a “phase control relay” that continuously
checks the phases. In case the phases are connected in reversed or if there is unbalance or
interruption in your voltage, the phase control relay will prevent operation of the compressor.
In this case, a signal behind the phase control relay that indicates the phase error warns you.
When the phases are connected reverse, switch off the energy and switch the position of main
cables of the compressor. In case of interruption or phase unbalance, as this problem is
related with the network contact an electrician or related institution.
9 When the energy and air lines of your compressor are completed, inform your service for
commissioning. Our service will perform the general inspections, start up the compressor and
supply you beneficial information related to your compressor and its maintenance. If you want
to start up the compressor by yourself read this handbook very carefully. Performing an
erroneous process may be hazardous for your compressor facility or the personnel working in
this region.
9 Check the oil level. On the oil receiver body there is a
transparent hose for easily seeing the oil level (on the belt
driving models). Check the oil level when compressor is at
the stop position. During operation the oil level may vary.
9 If the oil level is missing, complete it. Information related to
oil is described in section 5 (MAINTENANCE), part
“COMPRESSOR OIL”.
9 Oil level should not be below the mid-point of the hose
9 Check the internal components and connections of the
compressor. Make sure that during transportation it has not
been damaged.
9 Oil filling tap is on the compressor unit for the direct drive
models. While compressor is not working you can check the
oil level.
9 Oil level should reach beneath the pitch of the tap
9 Apply energy to compressor and see if the light is ‘on’ above
phase control relay in the electric board. If it is ‘on’ electric
connection is regular. If it is ‘off’ phase row is wrong
9 Apply energy to the compressor and check whether the
compressor motor is running in correct direction. The running
direction control of compressor: should be made during
commissioning. For this, remove necessary cover.
Page 18

9 By looking at the screw pulley of the compressor; press
the
“Start “ button and run the compressor for a
short while (1-2 seconds) and stop it by pressing
emergency stop button. When looked from fan side, it
should rotate in counter clockwise direction. (That is
indicated by an arrow)
9 If the rotation direction is correct, restart it after 1
minute.
9 By closing the valve at the outlet of the air receiver
allows the tank to fill.
9 See that the pressure is rising from the pressure gauge
over the control panel.
9 See that the pressure reaches the adjusted value and
the compressor is at idle.
9 If the value of the air pressure in tank does not drop; compressor will automatically stop at idle
after a short time. After waiting a couple of minutes, by opening the tank outlet vane observe
that the compressor is loading at demanded pressure level.
9 After 10-15 minutes, check the operating temperature of your compressor and see that it is
normal (80-90 °C). Switch off the energy of compressor by stopping and check internal
accessory of compressor by eye. This is very important against the probability of oil leak or
loosening
9 All the functions and reliability of your compressor has been tested after manufacture. The
above mentioned information of commissioning is against the probability of your compressor
being damaged during transportation. If you can not see a failure status after all controls you
can start up the compressor.
4.5 DAILY OPERATION
At normal days before running your comp ressor you ma y perfor m some simple c hecks and after wards
run it. The maintenance activities are explained in the section 5. (MAINTENANCE), 5.2 DAILY
MAINTENANCE part.
9 Observe that there is no failure warning signal on compressor panel.
9 Observe that there is no oil leak or damage by looking at the internal accessory.
9 Run the compressor and observe how it works for short time.
9 Look at the front panel and observe that operating pressure and temperature values are
normal.
9 While the compressor running on load, observe the oil flow at oil return line.
These simple checks may cause you to early detection of failures and save you from loss of time from
unnecessary stopping.
4.6 STOPPING THE COMPRESSOR
To switch off the compressor press the
stop button. Your compressor will first go into idle and stop
within 20-30 seconds. After the compressor stops observe that whether or not there is any damage, oil
leakage etc in the inside by opening the covers.

SINCE YOUR COMPRESSOR IS A COMPLICATED MACHINE; MAINTENANCE
ACTIVITIES PERFORMED BY UNAUTHORIZED AND NON TRAINED PERSONNEL WILL
ABOLISH ALL GUARANTEE AND MAY CAUSE UNDESIRED DAMAGE A ND INJURIES.
While the compressor is running never remove any cover or part. Prior the
maintenance; switch off the energy of compressor from the main switch. Remove the
compressor from the pressure on the utility line and ensure that all pressure inside
the compressor is discharged.
Prior the maintenance, read this handbook carefully; Performance of maintenance by authorized
personnel will lengthen the life of your compressor.
5.2 DAILY MAINTENANCE
9 Check the compressor oil level.
o There is a transparent hose for indicating oil level on the oil receiver body. Check the oil
level when the compressor is stopped (during operation oil level may vary). If oil is missing
refill it. If you are frequently adding up oil, this means that there is a problem with your
compressor. In order to understand this; review the section 7. (TROUBLESHOOTING)
part.
9 During operation, check the failure warnings and operating values from the control
panel.
9 Discharge the water collected in the air receiver by opening the valve under the tank
5.3 PERIODIC MAINTENANCE
For performing the periodic maintenance read thoroughly the maintenance instructions to be
mentioned in the following pages.
WEEKLY MAINTENANCE

5.4 MAINTENANCE INSTRUCTIONS
COMPRESSOR FLUID
o In our compressors HERTZ KOMPRESSOREN SMARTOIL 2000 type of oil is being used.
This oil is specially produced by taking into account of compressor operation type as you will
se below.
o As the chemical structures and contributions of different types of oils are different; mixing them
with each other or using them in the compressor may cause a severe damage with a high
cost.
o Do not put any oil additive in the compressor oil as in the motor oils. As the oil that you use
has been prepared specially for the compressor; it already includes this type of additives.
o In case of using engine oil, hydraulic oil etc; these two types will get mixed and become paste
consistency and this immediately impairs all the filters of your compressor. If you keep
operating this way, there may be stationary damages in your airend unit in a few days.
o For this reason do not keep other lubricating oils beside your compressor. Becau se, your
maintenance operator may accidentally use it.
o In addition if you are in need of long life synthetic oil; contact our service and sales
departments.
HERTZ KOMPRESSOREN SMARTOIL 2000
HERTZ KOMPRESSOREN SMARTOIL 2000 is high quality oil developed for screw type compressors.
As the property of separation from water and air is outstandingly developed and as it has a good
oxidation resistance; it is an ideal oil to be used in screw type compressors.
• Oxidation resistance
High temperatures are formed during compression of air. The oil that does not have oxidation
resistance starts to leave oxidized impurities at some points. This causes decrease in efficiency and
increase in maintenance costs. HERTZ KOMPRESSOREN SMARTOIL 2000 prevents the oxidation or
minimizes the expense due to the additives included.
• Protecting the parts against corrosion
By protecting the parts against corrosion it lengthens their service life.
• The property of well separation from air
By rapidly separating from air it prevents the cavitations and contributes the increase of compression.
• Gasket Compliance
HERTZ KOMPRESSOREN SMARTOIL 2000, complies with all the gaskets used in the compressor
• Health and Job Safety
The skin contact of used oil should be especially avoided and in case of contact must be washed with
soap and water. For more information see section 1 (safety)
• Environmental protection
Never pour the used oil to soil and water channels. Do not burn. If possible accumulate them at a
defined collection point and remove them per legal regulations.
• Typical physical properties

9 Switch off the compressor.
9 If the compressor is already cold, first run it 5-10 minutes for warming up of oil and switch it off
again.
9 Wait for 1-2 minutes for internal pressure discharge and oil to strain down.
9 Remove the oil charging plug.
9 Discharge the oil completely by opening the oil discharge valve. After the oil flow is finished,
close the oil discharge valve.
9 Fill the new oil.
9 Replace the oil filter by new one and manually tighten.
9 Complete the connections by installing oil charging plug.
9 Run the compressor for a few minutes for checking the internal accessory leaks.
9 After switching off the compressor wait for the fall down of oil and check the oil level. If it
incomplete fill it.
Only use original spare parts for avoiding damage of the oil filter element and your
compressor. The maximum pressure values of other type filer elements may no be
sufficient.

PANEL FILTER REPLACEMENT
o Panel filter keeps the dust trying to go inside the compressor. Filter change depends on
the ambient conditions and maintenance but should be changed every 2000 hours or 6
months
To change the panel filter;
9 After switching off the compressor remove the screws connecting the top perforate to
suction cowling.
9 Remove the old panel filter, replace the new filter in the same direction (due to its structure;
the panel filter’ upper side is loose and the bottom side is tight).
9 Tighten the screws connecting the top perforate to the suction cowling.
INTAKE FILTER REPLACEMENT
o Intake filter keeps the thin dust inside the suction air. Filter change depends on the
ambient conditions and maintenance but should be changed every 2000 hours or 6
months
- BELT DRIVEN MODELS - DIRECT DRIVEN MODELS
For replacing the intake filter;
9 Switch off the compressor. By removing the nut that is tightening the filter top cover,
remove the top cover and filters.
9 Clean the inner surface of the filter bottom cover with a cloth. Do not clean the dirt by
compressed air (it may go inside the intake valve).
9 Replace the new filter and close the top cover and make sure that filter is properly oriented
between the covers.
9 Mount the nut and washer of top cover.
9 If you will keep the filter in your stock preserve it in a clean place or its case.

SEPARATOR ELEMENT REPLACEMENT
- BELT DRIVEN MODELS - DIRECT DRIVEN MODELS
SEPARATOR ELEMENT
Change the separator element every year. If compressor runs more than 4000 hours change the
separator every 4000 hours
To change the separator element;
9 Stop the compressor.
9 Evacuate all internal pressure
9 Remove the separator element with filter key
9 Oil the gasket of new separator element
9 Place the new separator element and tighten it
9 Start compressor and check if there is any leakage on the gasket and connections
MAINTENANCE OF OIL RETURN (SCAVENGE) LINE
- BELT DRIVEN MODELS - DIRECT DRIVEN MODELS
SCAVENGE LINE SCAVENGE ORIFICE
o When the separator filter is separating the air from oil, some quantity of oil penetrates into the
filter element. This oil is recovered to the system by oil return line.
o When the compressor is operating at load, the oil flow from the scavenge hose should be
seen.
o If the orifice in the scavenge line gets blocked, the oil level rapidly decreases and oil penetrate
into the compressed air system.
o When discharging water underneath the air receiver; in case you observe oil or during some
checks the oil level is dropping, the scavenge line might be blocked. By stopping the
compressor remove the scavenge line and clean the orifice on the scavenge line by
compressed air.
Page 24
21
o Do not expand the diameter of the scavenge orifice, otherwise the capacity of your
compressor reduces.
THE MAINTENANCE OF COOLER
o For keeping the cooler clean, you should not hinder the cleaning of the panel filter.
o As the cooling air passes between the cells of the cooler, small amount of dust goes between
the cooler cells and this start to block the cells. Clean this by spraying compressed air
between the cells from the opposite of cooler (from outside to inside).
o When the dust between the cells mixes with oil, it may get hardened by sticking. In this case
clean this by spraying an industrial cleaner between the radiators cells. For performing this, if
necessary remove the cooler.
MOTOR MAINTENANCE
For long life and effective use of the electrical motors you should consider a few important points.
o Make the grounding of the compressor properly.
o Do not change the pressure related with the compressor operation, thermal current and time
adjustments. When the adjusted value is exceeded, the motor current will increase as the load
will increase. This situation may cause burning down of your motor.
o Do not use products like the belts, separator and oil filters that have complete their service life.
The maintenance activities that are no performed on time will force the system mechanically
and therefore increase the load of your motor and compressor and shorten its life.
o Keep the cooling fan, ventilation channels and the screen of the fan protective cover clean.
o Your elevation from sea level and medium temperature directly affects the cooling coefficient
of the motor. In standard, your motor operates without problem at 1000 meters altitude and at
40 C° medium temperature. You may have to review the loading ratio at higher altitudes and
warmer places.

TROUBLESHOOTING
6.1 INTRODUCTION
The information in this section is based on the experience gained by the service activities and tests
conducted at factory.
The indications and reasons of failures are ordered according to the results obtained from the
warnings of our company and the experience of the service personnel.
According to the structure of the compressor, as the systems and failures are interrelated; prior
making any repair or part replacement the reason of failure should be determined.
For the problems to be encountered, it is beneficial to make an eye inspection.
Good Tracing of failure, prevents the undesired damages that may occur during repair.
Firstly;
9 Check the electrical connections for the possibility of looseness.
9 Check the parts that may be influenced from short circuit and heat.
9 Check the damage and looseness that may form at air and oil circuit hoses, pipes and
connections.
If you have tried all the ways described in this handbook for eliminating the failure and the problem
still continues; please contact our company or service department.
From the point of your speed and reliability having all kinds of corrective action,
maintenance and repair works to be done at our service companies is the best way
for your compressor and your facility. All kinds of works carried out without
sufficient knowledge may cause wrong results, unnecessary interruptions of your
facility or more costly damages.
6.2 PROBLEMS AND SOLUTIONS
1- COMPRESSOR DOES NOT OPERATE
1- NO ELECTRICAL POWER
CHECK THE VOLTAGE FROM INPUT TERMINAL BLOCK
2- CONTROL OR INPUT FUSE IS BLOWN, MAIN SWITCH TRIPPED
CHECK THE FUSES
3-VOLTAGE IS LOW, UNSTABLE OR OPPOSITE
OBSERVE THE WARNING ON THE PHASE CONTROL RELAY
4-COMPRESSOR HAS STOPPED FOR ANY KIND OF FAILURE
OBSERVE THE WARNING ON THE CONTROL PANEL.
5-OPERATOR TRY TO START WHEN THE DISCHARGING DELAY TIME.
AFTER STOPPING THE COMPRESSOR, IT SHOULD NOT WORK FOR 1 MINUTE FOR
DISCHARGING OF INTERNAL PRESSURE. WAIT FOR “X10” LEDS BLINKING STOP.
2- COMPRESSOR IS HARDLY WORKING
1- THE CROSS SECTION OF POWER CABLE IS INSUFFICIENT.
THIS PROBLEM CAN BE ENCOUNTERED ON CONNECTIONS MADE THINNER CABLE DUE TO
VOLTAGE LOSS. WHEN YOUR COMPRESSOR IS IN STOP POSITION, MEASURE THE INPUT
VOLTAGE AND WHILE MEASURING RUN THE COMPRESSOR. IF THE VOLTAGE IS DECREASE %
5 (380> 360) AND BELOW, THE CABLE CROSS SECTION IS INSUFFICIENT. MAKE THE
CONNECTION WITH A SUITABLE CROSS SECTION.
2- VOLTAGE IS LOW
IF THE LINE VOLTAGE IS % 5 LESS THAN THE COMPRESSOR ADJUSTED VOLTAGE, THE
PROBLEM MAY ARISE FROM THE NETWORK OR FROM THE ESTABLISHED POWER OF YOUR
FACILITY.
3- THE AMBIENT TEMPERATURE IS LOW
IF THE AMBIENT TEMPERATURE IS LOW THAN + 2 °C, THE OIL MAY THICKEN AND THIS MAY
ENFORCE THE OPERATION OF YOUR COMPRESSOR.
4-INTAKE VALVE IS DEFECTED
THE INTAKE VALVE IS CLOSED AT FIRST RUN UP. IF THERE IS A MECHANICAL PROBLEM, IT
MAY STAY OPEN. THIS WAY THE COMPRESSOR TRIES TO START UP AGAINST LOAD AND
HARDLY SPEEDS UP. WHEN THE COMPRESSOR IS AT STOP AND THERE IS NO INTERNAL
PRESSURE, OBSERVE THAT THE INTAKE CLAPET IS FULLY CLOSED. THE CLAPET MIGHT BE
STUCK AT OPEN POSITION. INFORM THE SERVICE.
5-THERE IS A MECHANICAL PROBLEM AT MOTOR OR COMPRESSOR UNIT
Page 26
23
AFTER DE-ENERGIZING THE COMPRESSOR CHECK WHETHER THE BELTS ARE FREELY
ROTATING. IF THE ROTATION IS MORE DIFFICULT THAN NORMAL, THERE MAY BE
MECHANICAL DAMAGE AT MOTOR OR AT COMPRESSOR UNIT; INFORM THE SERVICE.
3- COMPRESSOR DOES NOT PRODUCE AIR. (DOES NOT GET LOADED)
1- THE COMPRESSOR DOES NOT TRANSFER FROM STAR TO DELTA.
THE STAR DELTA TIME ADJUSTMENT MAY BE CHANGED. CHECK THE ADJUSTMENT (4-8
SECONDS). BY ENGAGING THE COMPRESSOR, CHECK THE CONTACTORS AT THE STARTER
BOX. AT THE END OF ADJUSTED PERIOD, THE K3 (STAR) CONTACTOR SHOULD RELEASE AND
K2 (DELTA) CONTACTOR SHOULD EXTRACT. IF IT DOES NOT, THE CONTACTOR COIL
CONNECTION COULD BE LOOSE OR THE COIL COULD BE BURNED.
2- THE INTAKE VALVE IS DEFECTED
THE CLAPET OF THE INTAKE VALVE MAY BE STUCK, O-RINGS AND GASKETS MAY BE
DAMAGED
3- MINIMUM PRESSURE VALVE IS DEFECTED
AS THE O-RING AND GASKETS OF THE MINIMUM PRESSURE VALVE ARE DAMAGED, IT CAN
NOT KEEP THE INTERNAL PRESSURE. IF INTERNAL PRESSURE DOES NOT RISE, THE INTAKE
VALVE CAN NOT OPEN AND THE COMPRESSOR CAN NOT BE ENGAGED. REPLACE THE
GASKETS AND O-RINGS.
4- THE SOLENOID VALVE IS DEFECTED
CHECK WHETHER THE SOLENOID VALVE RECEIVES THE CONTROL ENERGY (IN DELTA

LINE HOSE OR SCAVENGE SIGHT GLASS. IF THE OIL IS NOT PASSING, STOP THE
COMPRESSOR. CLEAN THE SCAVENGE ORIFICE WITH COMPRESSED AIR. OBSERVE THE OIL
FLOW AFTER OPERATING THE COMPRESSOR. COMPLETE THE LOST OIL
2- THE SEPARATOR ELEMENT IS DAMAGED
(IF THE SCAVENGE IS WORKING PROPERLY, THE PROBABILITY OF THE SEPARATOR ELEMENT
BEING DAMAGED INCREASES). IF YOU SEE OIL COMING FROM THE AIR RECEIVER DURING
WATER DISCHARGE, REPLACE THE SEPARATOR ELEMENT.
3- THERE IS LEAK AT THE OIL CONNECTIONS
CHECK THE OIL CIRCUIT CONNECTIONS OF THE COMPRESSOR. AT THE POINT OF LEAK, OIL
DEPOSITS MIGHT BE SEEN ON FLOOR. BY CHECKING THE COUPLING AND CONNECTIONS AT
OIL CIRCUIT, TIGHTEN THEM. IF THE OIL LEAK IS NOT PREVENTED, INFORM THE SERVICE.
