5.7 Changing the oil
This section outlines the procedure for changing the oil.
The oil may only be changed when the unit is switched off and
fully depressurised! The unit should be at operating
temperature (approx. 60°C - 80°C) when the oil change is
carried out.The unit should be run with the type of oil best
suited to its operation. The standard oil used at the factory is
Shell Corena D68. This type of oil is recommended.
Any other types of oil used should be equivalent to Shell
Corena D68. Only refill the unit with oil of the same make and
the same grade.
Do not mix oils of different kinds!
Follow the safety instructions for venting the unit (see
Chap. 5.3)!
Step Operation
1
Switch off the unit and take measures to prevent it
from being restarted. Allow the unit to cool to approx.
70°C and then remove the pressure as described in
Chapter 5.3.
2
Take a receptacle suitable for collecting the oil and
position it under one of the drain plugs (hexagon
head) on the base of the separator tank and then
unscrew and remove this plug.
3
Drain all the oil from the separator tank then replace
the drain plug and tighten.
4
Pour the new oil into the filler neck up to the
maximum level (see Chap. 5.5) and replace the oil
filler plug firmly by hand.
5
Switch the unit on and, for the first two or three
times, switch it back off again after approx. 5
seconds only. This allows the oil to be distributed in
the unit before it is put on load.
6
Switch the unit on and allow it to run for approx.
three minutes.
7
Check the oil level and, if necessary, refill to
maximum mark (see Chap. 5.5).
8
Check drain plug and oil filler plug for leaks.
9
Record the oil change on the maintenance check
sheet.
Comply with environmental guidelines when disposing of
used oil!
