6.2.1

CHECK THE OIL LEVEL AND THE ABSENCE OF WATER VAPOUR CONDENSED IN THE TANK

Check that oil level is at mid-range of the oil level indicator light or the oil viewer. If not, see instructions in paragraph

5.1.1. "Filling the oil tank".

Check oil conditions. When dark or cloudy, oil has been contaminated by intake substances and must be changed.

Check there are no water vapours condensed on the bottom of the tank through the oil viewer. Otherwise, open the oil

discharge valve slightly, let the condensed water vapour flow out and close it again as soon as the oil starts to come out.

Then, check the oil level and, if necessary, top up following the indications in paragraph 5.1.1.

6.2.2

CHECK THE STATUS OF THE INTAKE FILTER (ONLY LB.5WR)

Before operating on the intake filter, isolate the pump from the user system through a valve, or restore the

atmospheric pressure inside the filter. For this purpose there is a valve on the filter that can be opened to restore

the pressure inside see chap. 3.3).

If there is any liquid in the filter, it is necessary to drain it by opening the valve on the bottom of the filter. When all

the liquid has been removed, close the valve again.

6.2.3

CHANGE OIL

Change oil as follows:

• let the pump run with closed suction intake for about 10 minutes first so oil will become thinner;

• stop the pump and disconnect it from the mains;

• undo the oil filler plug;

• get a container large enough to hold all oil and open the oil drainage valve;

• drain out all oil;

• close drainage valve and fill in fresh oil through the filler plug up to mid-range on the oil sight glass;

• close the oil filler plug;

• connect to mains again and verify correct rotation direction of the pump (see chap. 3.3.);

• let the pump run with closed intake for a few minutes and then, if necessary, top up oil if necessary.
