9.12.1 Oil change using external pressure source
Drain the oil from the oil separator tank:
Close the ball valve (1).
Insert the maintenance hose --- ball valve closed --- in the hose coupling (3) on the oil
separator tank (5).
Connect the maintenance hose to external pressure source. Pressurize the oil separa-
tor tank (5) by slowly opening the ball valve (7) until the pressure gauge (2) on the oil
separator tank (5) shows approximately 43.5 psig.
Remove the maintenance hose from the hose coupling (3) on the oil separator
tank (5).
Prepare a clean container to catch escaping oil.
The container must be large enough to hold the total oil content of the
compressor unit (see chapter 1.7).
Insert the maintenance hose --- ball valve closed --- in the hose coupling (12) on the
oil separator tank (5).
