When a failed Rolls Royce air conditioning compressor is replaced by a new Rolls Royce a/c compressor, it is so important to have the lubricant distributed evenly across the Rolls Royce air conditioning compressor and the a/c system before engaging the system for the first time.

If this is overlooked and the Rolls Royce air con compressor is engaged immediately after is has been charged with
refrigerant, it may happen that all the oil in the Rolls Royce a/c compressor will be pushed out all at once while there is no oil yet to enter the Rolls Royce air conditioning compressor on the other side. This is caused by the fact that it takes some time for the oil to spread across the system and mix with the refrigerant. Eventually the Rolls Royce ac compressor may be damaged because of a lack of lubrication during the first few minutes of operation.

This will of course be more problematic after the system has been flushed, this will mainly be the
case after the Rolls Royce air con compressor has suffered a catastrophic failure with metal particles from the Rolls Royce a/c compressor being spread across the entire system.

A rule of thumb guide when installing a new Rolls Royce air con compressor is to manually turn the Rolls Royce a/c compressor pulley to make sure that the oil is distributed through the Rolls Royce air con compressor evenly. Experienced engineers will normally turn the Rolls Royce ac compressor 10—15 times to ensure that oil has been pushed around the system.

There is still more to do to prepare the Rolls Royce air con compressor, knowing and following the procedure will be of great importance if a newly installed Rolls Royce air conditioning compressor should fail after a short period of time and within its warranty period. There is no bigger disappointment than having a warranty claim denied because something as simple as the following procedure has been overlooked.

Generally new Rolls Royce a/c compressors are supplied charged with oil, but it is always recommended that you
check this by draining the new Rolls Royce air con compressor to check the amount of oil in the Rolls Royce air conditioning compressor.

Then once you have removed the old Rolls Royce a/c compressor you should do the same again, empty the old Rolls Royce ac compressor of oil to see how much oil was in it and then fill the new Rolls Royce air con compressor with the same amount this is to avoid over charging the system with oil.

After this has been done and the a/c compressor has been fitted, you do not engage the air con compressor with
the engine running until the following steps have been followed.

1, Open all air louvers at the dash board, 2, Start the engine and let it stabilise at idle speed 3, Set the
blower at maximum speed, 4, Engage the a/c system and operate it continuously for 2 minutes at below
1500 rpm.

After the two minutes the Rolls Royce air con compressor oil will have distributed evenly throughout the Rolls Royce a/c system.
