4.

Switch off the filter unit at the main switch and unplug
the power connector.

5.

Loosen the filter bowl

(600)

by turning it counterclock-

wise.

If required, use a wrench

= 24 mm.

6.

Unscrew the filter bowl

(600)

by turning it counterclock-

wise by hand.

NOTICE! A small amount of fluid will drip out of the
connector head (110) and will collect in the drip tray
(420). If the filter unit is connected to a system, oper-
ating medium can continue to flow out of the hoses /
pipes. Make sure that there is always ≈ 0.5 liter of
medium in the filter cartridge.
