1) TAN (Total Acid Number) is only non-ammonia applications
2) SAN (Strong Acid Number) is only reported for non-ammonia applications
A report is compiled for every sample received. This report will describe:
• whether the oil can still be used without taking any further action.
• whether the oil can be used after it has been filtered through a very fine filter. If this is
necessary, the oil must be pumped directly from the compressor unit through a 3 mi-
cron filter and back to the unit. The system must be completely closed to prevent the oil
from being affected by moisture in the air.
• whether the oil can no longer be used.
The report will always be sent to the address stated on the sample label included in the form
set. A copy will be sent to Johnson Controls Denmark so that we are in a position to advise
you, if required.
11.12 Charging compressor with lubricating oil
Caution!
Only charge oil when the unit pressure is below 6 bar!
Oil charging is carried out by means of a portable oil charging pump, see Fig. 86. Proceed as
follows:
1. Connect the high-pressure hose, pos. 7, to the service valve, pos. 106, on the unit via
the non-return valve, pos. 12. Use the correct reduction nipple. See Fig. 87.
2. Place the free end of the suction hose from the pump, pos. 1, together with the by-pass
hose, pos. 2, in the barrel.
3. Open the ball valve, pos. 9, and service valve, pos. 106, and start the pump, pos. 5.
