Shorter maintenance intervals may be required according to operating conditions (high temperature of intake gases,
intake gases containing condensable vapours, etc.).
6.2.1 CHECK OIL LEVEL
Check that oil level is at mid-range of the oil sight glass. If not, see instructions in the following paragraph.
Check oil conditions. When dark or cloudy, oil has been contaminated by intake substances and must be changed.
6.2.2 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 drain plug;
• Drain out all oil;
• Close drain plug and fill in fresh oil through the filler plug up to mid-range on the oil sight glass;
• Close the oil filler plug;
• Remove all oil spills from the pump and/or floor.
• Connect to mains again and verify correct rotation direction of the pump (see chapt. 3.3.);
• Let the pump run with closed intake for a few minutes and then, if necessary, top up oil if necessary.
HAZARD
Wear appropriate personal protection equipment to perform said operations.
HAZARD
Comply with local regulations regarding the collection and disposal of used or polluted oil.
6.2.3 CLEAN RADIATOR, MOTOR FAN GUARD AND CLEAN THE PUMP
Radiator, motor fan guard and the pump should be cleaned to remove any dust deposits.
This can be done using compressed air and a dry cloth.
Be careful not to damage the components of the oil cooling radiator (where present) by approaching the jet
of compressed air or by exerting excessive pressure with the cloth.
Do not use fluids or substances other than those indicated.
HAZARD
Wear appropriate personal protection equipment to perform said operations.
6.2.4 CHANGE THE AIR EXHAUST FILTER
The air exhaust filter must be changed when it is damaged or clogged or when it has reached its authorised life as
per Chap 6.2.
Only use original DVP filters from the Air Exhaust Filter Kit (see Chap.6.3). Use of parts other than those approved
by DVP can cause deterioration of the pump.
The signs showing a filter is clogged or damaged are increased exhaust fumes, increased noise-level and
consumption of electricity (see Chap.9 points C and E).
