1.2 Functional Checks
1. Insert the isolator fuses and switch on the
power supply to the compressor.
2. Hand unload each 1st stage cylinder of the
compressor by moving the spring loaded cam
levers to the valve unloaded position.
3. Open cooling water valves to water-cooled
intercooler and aftercooler, if fitted and open
the intercooler vent/drain cock. Close the cock
when a full, air-free flow emerges.
4. Check the direction of rotation of the motor by
observing the direction in which the motor
kicks over when started. This may be
conveniently done by removing the clip-on
inspection panel in the top of the flywheel
housing and viewing the drive coupling. Correct
rotation is clockwise viewed from the motor
end of the compressor, as indicated by the
direction arrow on the housing.
Check for correct rotation of the fan motor on
the air blast aftercooler, if fitted. If rotation is
incorrect, stop the compressor immediately,
switch off the power supply at the isolator and
rectify the cable connections.
5. When the direction of rotation is correct, start
the compressor and allow to run for 10 - 15
minutes in the unloaded condition. Check that
the oil pressure is more than 1.7 bar, settling
to 1.7 bar when the compressor reaches
operating temperature.
6. On lubricated compressors only, close the
hand unloaders and run the compressor for a
further 10 - 15 minutes to clear all traces of
inhibitor from the cylinders.
7. Stop the compressor .
8. Connect the air delivery manifold flange to the
air receiver.
9. Move the hand unloaders to the valve unloaded
position, start the compressor and when it is
running evenly close the hand unloaders.
10. Run the compressor on load with a receiver
valve open to maintain the running loaded
condition until full operating temperature is
reached (approximately 20 minutes from cold).
11 . Check the setting of the switching
thermometers as follows:-
Using the trip needle adjusting knob on the
face of each thermometer, set the trip needles
to 15°C above the normal running temperatures
indicated.
Note: The minimum oil pressure switch is
preset at 1 bar and should not require
adjustment.
12. Check the complete installation for leaks and
excessive temperatures.
13. Close the receiver valve and check that the
compressor runs correctly under the influence
of the air governor or pressure switch. If
adjustment is necessary , refer to section
below headed 'Adjustments'.
14. Run the compressor for 1 hour, checking
continually for correct loading and unloading,
temperatures and pressures. Record
temperature and pressure readings to provide a
basis for assessing future performance.
1.3 Routine Starting
1.3.1 Air Governor Control
1. Check crankcase oil level.
2. Operate hand unloaders on 1st. stage cylinder
heads.
3. Open cooling water flow, if applicable.
4. Switch the power supply 'ON' at the isolator
and operate starter.
5. When the compressor is running steadily,
close hand unloaders.
1.3.2 Optional Control Panel
1. Check crankcase oil level.
2. Operate hand unloaders on 1st. stage cylinder
heads.
3. Open cooling water valves, if applicable.
