• 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 MOTOR FAN GUARD EAND 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.
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).
It is possible to measure the level of clogging of the oil separator filter by looking at the ∆P of the filter with the pump
warm. On pumps equipped with a measuring point for ∆P it is possible to check the filter by attaching a gauge or
the accessory code SIF.2 to it. For pumps without this facility a measuring instrument can be connected in place of
the oil filler cap.
For a pump operating and with hot oil the filter is clogged if the value of ∆P is greater than 0.7bar (at sea level). If
this is the case the oil separator filter must be replaced.
6.2.5 CHANGE VANES
The instructions for replacing vanes are available upon request.
6.3 SPARE PARTS
Use Original Spare Parts to replace pump parts.
When purchasing spare parts, always quote the serial number and model of the pump (these can be found on the
identification plate) as well as the spare part purchase number.
