Changing the Filter Element - Toploader
The filter element must be changed at the very latest when the visual clogging
indicator shows a red marking.
The filter element has a bayonet seal - this simplifies changing the element. The
only intervention required is to turn the element or its mounting parts 90° clockwise
or counterclockwise.
1.
Switch off the system, make sure that no
operating fluid can flow out of the lines into
the filtration unit, and make sure that the unit
cannot be switched on again during
maintenance.
Depressurize the filter housing. To
accomplish this, carefully open the air bleed
screw (Air Bleed) on the filter housing cover
(do not unscrew completely).
Be careful when the operating
medium flows out.
2.
Put a suitable container in place to catch the
medium in the filter housing.
The volume is ~ 3 liters.
Empty the filter housing through the drain
plug (Drain) on the connection part.
Without the proper drainage
equipment, the draining fluid can flow down
to the electric motor.
3.
Loosen the tensioning clamp on the filter
housing cover by completely unscrewing the
nut.
Remove the housing clamp.
