G - Draining condensation water
(see B chapter 1)
Condensation water prevents proper lubrication. The resulting
substantial wear leads to a reduction in the lifespan of the CP
Compressor. 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
Compressor has been shut down. It can be carried out for example
on the morning of the start-up.
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 - Motors

The motors must be lubricated in accordance with manufacturer
instructions printed on the motor plate.
Type of lubricant for motor IP55: ASONIC HQ 72-102
In the event of a motor replacement, check for the correct direc-
tion of rotation by starting then IMMEDIATELY stopping the
motor. If the direction of rotation is incorrect, change two phases
on the motor power cable in the electrical cabinet.
If you have chosen the phase control option check that the
controller indicator is on (sequence correct).

I - Coupling

Non-lubricated flexible coupling doesn't require any particular
maintenance. It is made up of two half-flanges and one or more
intermediary rubber elements. The rubber elements must be
checked periodically for any cracks, tears, loss of elasticity or
signs of excessive wear.
Machine running at fixed speed
Alignment
Perfect alignment is obtained automatically thanks to the cen-
tring bell between the compressor and the motor.
WARNING
The retainer locks of the two shafts must be positioned at 180°
from each other for proper balance.

J - Suction control system (see Fig. 25)

If the compressor's suction control system is showing signs of
malfunction (vibrations, noise, leaks, does not open or close), the
suction valve must be removed for inspection.

K - Temperature safety tests

(see Notice AIRLOGIC - E chapter 1).
IF THE SENSOR IS NOT WORKING, IT MUST BE
CHANGED.

L - Refastening electric connections

A loosening of the electric power cables leads to the contactors
ove-rheating which can lead to their destruction.
Periodic refastening is therefore necessary at the star and triangle
line contactor arrivals and departures.
All electric power supply to the machine must be cut off before
opening the electric cabinet.
M - Decommissioning the compressor at
the end of its useful life
1. Stop the compressor and close the air outlet valve.
2. Unplug the compressor from the electric supply.
3. Decompress the compressor : unplug the 4/6 piping on the
oil separator cover.
4. Close and decompress 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.
