A - Oil level and change (see fig. 19)
(see B Section 1)
The recommended oil used for the first compressor fill up is a
mineral oil with the following properties :
- viscosity: 40 cSt at 104 °F
- viscosity index: 90 minimum
- antioxidant additives
- anti-rust additives
- anti-foam additives
THE FIRST OIL CHANGE MUST BE CARRIED OUT
AFTER THE FIRST 500 HOURS OPERATION.
Using a synthetic oil for compressors is also acceptable and means
less frequent oil changes: please speak to us about the compatibility
and oil change methodes.
The oil change and the replacement of oil filter must be carried out
when the indication is seen on the electronic controller and when
the corresponding time counter reaches "0" (refer to electronic
plate manual Section 1 E ).
Drain the compressor when warm. For this, shut it down taking
care to disconnect the power cable. Release pressure in the tank
by unscrewing the filler plug by a single turn. Open the purge
valve and drain the oil. Do not forget to close the valve after
draining the oil.
After maintenance, reset the time counter which tells you how
long you have before the next oil change is due, refer to electronic
plate manual Section 1 E.
OIL LEVEL
When the machine is not running, the MAXIMUM oil level cor-
responds to the top part of the green area, and the MINIMUM
level is represented by the low part of this green area.
CHECKING THE OIL LEVEL MUST BE CARRIED OUT
JUST AFTER STOPPING THE MACHINE (THERMOSTAT
VALVE OPEN).
DRAINAGE UNDER PRESSURE
So as to carry out a quick and full oil change, your CPVS is equip-
ped with a system that allows low level pressure to be maintained
in the oil circuit. This pressure is shown by the pressure gauge
situated in the tank. (see Notice AIRLOGIC - E Section 1).
Proceed as follows :
• When hot, compressor in load for programming a shutdown under
pressure (refer notice AIRLOGIC § 4.9.3). The machine is
emptied and stops automatically.
• Change the oil by opening the oil change valve very slowly.
• When there is no pressure left in the oil tank, change the oil filter
cartridge.
• As soon as the oil is no longer flowing, close the valve and refill
with new oil.
• Reinitialise the timers that will warn you when to carry out the
next oil change and the next oil filter change
(see the AIRLOGIC Manual - E Section 1),
• Reseal the filler cap when replacing it and check that all openings
are properly closed.
• The machine can be restarted only after pressing the button C
several times to return to STATE 0.1. Check the clamping of
connections.
• After restarting, check that there are no oil leaks.
NOTE
If the oil is in a bad state ; that is a pungent smell or contains
particles or varnish or other solid matter, the system will have to
be rinsed : pour about 50% or the normal contents of clean oil
and operate the unit for 3 hours and carefully change the oil.
During rinsing, leave the old oil filter cartridge in the machine.
B - Air filter
(see B Section 1)
The air filter is of the dry, encapsulated type. Change the
cartridge every 2,000 hours. Check the cleanliness of the filter
every week and change it if necessary. (see notice on the
electronic plate for resetting the time).
ATTENTION :
If you do not replace the filtering element when needed, per-
manent dirt build-up will result. This reduces the air inflow to the
compressor and could damage the oil separator and the compressor.

Replacement of the complete fan is recommended if one or more
blades are deformed or broken If replaced, check the fan rotation
direction reversal of the rotation direction will reduce machine
cooling and damage the motor in time.
