E - Oil separator cartridge (Fig. 12)
(see B Section 1)
The life time of the oil separator cartridge will depend on the
purity of the intake air, the regular oil filter replacements, the
quality of the oil used, the care taken when draining the conden-
sation from the oil tank and on the room temperature.
The oil separator cartridge (
item. 1 Fig. 12
) should be replaced
when the corresponding waening message is displayed on the
controller.
After replacing the oil separator cartridge, reset the counter, which
will let you know how much time is left before it needs to be
replaced.
Excessive oil consumption
Excessive oil in the discharged air and a sudden drop in the level
are signs that the oil separator cartridge has probably deteriorated
and must be changed. In the first place, the compressor must be
checked to make sure that there are no oil leaks and that the oil
scavenge line is working properly. The replacement of the oil
separator cartridge requires the removal of the right top panel.

F - Oil return pipe (see Fig. 13)
Placed under the compressor
• Dismantle the complete oil return check valve.
• Lift the oil stop valve pipe.
• Check the state of the o-ring (
item. 1 Fig. 13
).
• Reassemble.
• A dedicated kit allows to replace the complete check valve.
G - Draining condensation water
(see B Section 1)
Condensation water prevents proper lubrication. The resulting
substantial wear leads to a reduction in the lifespan of the CP
Compressors. It is therefore essential to drain condensation water.
Draining of condensates in the oil circuit
:
Draining will only take place at least 12 hours after the CP
Compressors has been shut down. It can be carried out for example
at start-up.
Fig. 13 - Oil return pipe
To do this :
- Slowly open the oil change tap and let the water escape.
- When the oil appears, close the valve immediately to avoid any
loss.
- Refill with oil if necessary.
H - Temperature safety tests
IF THE SENSOR DOES NOT DISPLAY THE RIGHT
TEMPERATURE OR GIVES AN ERROR MESSAGE ON
THE CONTROLLER DISPLAY, FIRST CHECK THE
CONNECTIONS AND CABLES. IT CAN ONLY BE
REPLACED IF IT HAS BEEN DETECTED FAULTY WITH
CERTAINTY.
I - Refastening electric connections
A loosening of the electric power cables leads to the contactors
overheating which can lead to their destruction.
PERIODIC REFASTENING IS THEREFORE NECESSARY AT
THE STAR/DELTA AND LINE CONTACTOR INPUTS AND
OUTPUTS. (SEE MAINTENANCE TABLE).
All electric power supply to the machine must be cut off before
opening the electric cabinet.
J - Decommissioning the compressor at the
end of its useful life
1. Stop the compressor and close the air outlet valve.
2. Disconnect the compressor from the electric supply.
3. Unload the compressor : unplug the 4/6 piping on the oil
separator cover.
4. Close and unload the section of the air network which is
linked to the exit valve. Disconnect from the compressed
air exit pipe from the air network.
5. Empty the circuits of oil and condensates.
6. Disconnect the compressor condensate piping from the
condensate draining system.
