Sampling Coolant; Changing Coolant Filter Element; Checking Separator Element; Changing Separator Element - Ingersoll Rand R4-11 kW Informations D'installation

„ Sampling Coolant
1. Bring the compressor up to operating temperature.
2. Stop the compressor.
3. Isolate the compressor from the external air system.
4. Press the emergency stop to vent the separator tank and airend.
Fixed speed compressors can take more than two minutes to fully
de-pressurize once stopped.
5. Draw a sample from the sump fill port. DO NOT draw a sample from
the drain port or coolant filter port.
Use a new hose on the pump for each sample. Failure to do this can give false
readings.
See Figure 3.

„ Changing Coolant Filter Element
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Loosen filter element with the correct tool.
3. Remove the filter element from the housing.
4. Place the old filter element in a sealed bag and dispose of in a safe
way.
5. Clean the mating face of the housing, taking care to avoid any
particles entering the machine.
6. Remove the new Ingersoll Rand replacement filter element from its
protective package.
7. Apply a small amount of lubricant to the filter seal.
8. Screw the new filter element down until the seal makes contact with
the housing, then hand tighten a further full turn.
9. Start the compressor and check for leaks.

„ Checking Separator Element
Feature available only on machines equipped with Xe-70 controller.
With the compressor running on load, check the separator differential
pressure via the controller. It will be necessary to change the element if the
differential pressure equals zero or exceeds 1 bar (12 psig).

„ Inspecting Airend/Pressure System/Receiver
At 2000 hour intervals, inspect the external surfaces of the airend including
all fittings, for visible signs of impact damage, excessive corrosion and
abrasions.
The receiver (if applicable) should also be tested and inspected in accordance
with any national or local codes that may exist.
„ Cleaning / Checking Scavenge Orifice
The orifice is similar in appearance to a straight tubing connector and will
be located between the 6 mm (0.25 in) O.D. scavenge line tubing and the
integrated separator/MPCV manifold.
The main body is made from 17 mm hexagon shaped metal and the diameter
of the orifice and a direction-of-flow arrow is stamped in flat areas of the
hexagon. The orifice should be examined and cleaned as recommended in
maintenance schedule.
To remove the scavenge orifice:
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Loosen element with the correct tool.
3. Remove the element from the housing.
4. Place the old element in a sealed bag and dispose of in a safe way.
5. Clean the mating face of the housing, taking care to avoid any
particles entering the machine. When changing the separator
element, inspect the internal components and surfaces. Any suspect
parts shall be replaced before the compressor is put back into
service.
6. Remove the new Ingersoll Rand replacement element from its
protective package.
7. Apply a small amount of lubricant to the element seal.
8. Screw the new element down until the seal makes contact with the
housing, then hand tighten a further 1/4 turn.
9. Start the compressor and check for leaks.

1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Disconnect the scavenge line tubing from end and unscrew from
integrated separator/ MPCV manifold.
3. Inspect orifice and tubing for clogging and clean prior to re-
installation. If there is any scaling or o-ring damage identified, the
scavenge orifice will need to be replaced before the compressor is
put back into service.
4. When the assembly is installed, confirm the direction of flow to be
correct. Observe the small arrow stamped in the center section and
ensure the direction of flow to be from the separator tank to the
airend.
