The replacement steps are as follows:
a. Press the Stop button and then switch off, isolate and tag-out the power supply to the
compressor.
b. Close the air outlet valve.
c. Wait at least two minutes for the pressure in the air-oil receiver to be completely released
and monitor the pressure gauge to confirm.
d. Use an oil filter wrench to remove the oil filter by unscrewing it anticlockwise.
e. Clean the sealing washer of the new oil filter and then apply a thin layer of clean lubricating
oil onto it.
f. Install the new oil filter by screwing it on clockwise until the sealing washer contacts the
oil filter base and then tighten it by hand a further ½ to ¾ of a turn.
g. Reset the ‘Oil F Used’ hours to zero via the user parameters menu on the controller.
5.3 Air-Oil Separator
The air-oil separator should be replaced after every 2,000 hours or 1 year, whichever occurs
first. In a dirty or dusty environment, the replacement period should be halved. It is not possible
to clean the air-oil separator element, only replacement is allowed.
If the air-oil separator is an external spin-on type, the procedure for replacing it is essentially
the same as that described above for replacing the oil filter.
Caution: When removing an external spin-on type of air-oil separator, the separator connector
stem may become partly or wholly unscrewed from its base. Use a spanner to check and tighten
the separator connector stem if necessary, taking care not to damage its sealing O-rings.
Caution: When replacing the air-oil separator, it is essential to prevent ingress of foreign matter
into the air-oil receiver.
If the air-oil separator is an internal cartridge type, it should be replaced in conjunction with
replacing the compressor oil and oil filter:
a. Drain the compressor oil and remove the oil filter.
b. Disconnect the hose and pipes as required to enable the lid of the air-oil receiver to be
removed.
c. Remove the bolts holding-down the lid of the air-oil receiver and then lift it up and away
while taking care not to damage the oil scavenge tube that’s affixed to its underside.
d. Remove the air-oil separator element and any associated gaskets or O-rings.
