Follow below procedure to replace the filter element:
1 Stop the pump. Switch off the voltage.
2 Remove the cover of the air filter. Remove the filter element.
3 Install the new filter element and fit the cover. Never install damaged filter element.
CAUTION
When placing the air filter element, verify that the seal is present and in good condition.
Cleaning the intake air filter element
1 Remove the intake filter element from the housing.
2 Clean the intake filter element in one of the following ways:
Hand washing:
Soak and agitate element in a warm water and mild detergent solution. Allow adequate time for the
element to air dry (24 hours minimum). Do not install a damp element. This will cause higher initial
pressure loss and rapid dirt loading.
Compressed air cleaning:
Using approximately 7 bar(e) ( 100 psi(g)), direct air flow at inside of element towards pleats. Blow
off the outside of the element directing the air flow down to avoid embedding dirt in the media. Blow
off the inside again to remove any dirt that might be on the clean side of the element.
Vacuum cleaning:
Point the vacuum cleaner to the dirty side (outside of element) only, using a vacuum of
approximately 100 mbar(a) (75 torr). A crevice tool is recommended.
Hand cleaning:
Hold element down with one hand and move other hand across the fins in a strumming motion. This
action will dislodge most of the dirt.
3 The element is ready to be reused.
6.2 Oil top-up
1 Remove the filler plug. Fill the gearbox with oil until the level reaches the top of the oil sight glass.
Take care that no dirt drops into the system. Refit and tighten the filler plug.
2 Run the pump loaded for a few minutes. Stop the pump.
3 Close the isolation valve and switch off the voltage.
 Wait 3 minutes for the pump to depressurize.
 Unscrew the oil filler plug just one turn to permit any remaining pressure in the system to
escape.
4 Fill the gearbox with oil until the level reaches middle of the oil sight glass. (See section “During
operation”).
5 Refit and tighten filler plug.
6 When the oil level is too low, repeat the steps 1 to 5.
6.3 Cleaning motor fan and vent holes
Motor fan, main cooling fan and vent holes should be kept clean. This can be done using compressed
air and a dry cloth. Do not use fluids or substances other than those indicated.
