– At the preferred lter installation position: Flush via the
return valve (1). This produces a large ow. As a result, the
ushing agent also ows through the upper part of the lter
cartridge (11). Pressure regulator approx. 0.15MPa; 1.5bar;
22psi.
– With a reversed lter installation position: Flush using
the spray gun. This is required, in the case of a reversed
installation position, so that the ushing agent ows
through the lter cartridge (11). Maximize the ow (remove
the nozzle, open the dosing valve if necessary).
2. Empty the pump in a controlled manner in accordance with
Chapter 8.2.4.
3. Place the grounded collection tank under the high-pressure lter.
4. Open ball valve (1).
5. Loosen union nut (3) with a size 70 wrench.
6. Unscrew the union nut (3) and lift slightly so that it does not get
dirty in the next step.
7. Remove the lter housing (2) with the union nut (3). The cone
spring (12) remains in the lter housing (2). If the O-ring (5) is not
damaged, it remains on the lter housing (2).
8. Remove the lter cartridge (11) and lter socket (10) from the
lter housing (2).
9. Clean all parts:
– Place the lter cartridge (11) and lter support (10) in
solvent. Clean using brush.
– Fill the lter housing (2) approx. 1/3 full with solvent. Close,
wearing a glove, and shake well.
– Clean the distribution housing (7) using a brush.
10. If necessary, replace the O-ring (5) and/or lter cartridge (11).
Order no., see Chapter 14.8.
11. Assemble all parts in reverse order. While doing so:
– Coat the thread of the distribution housing (7) with anti-
seize paste**.
– Coat the O-ring (5) and pressure ring (21) with Mobilux
EP2**.
– Observe the installation position of the lter cartridge (11):
Push the closed end with the lter identication ahead into
the lter housing (2).
– Make sure that the cone spring (12) is in the lter housing
(note the installation position). Press on the cone spring
after inserting the lter cartridge (11) and lter support (10);
the spring action must be noticeable.
– Tighten the union nut (3) by hand.
12. Close ball valve (1).
13. Fill the pump in accordance with Chapter 8.2.5.
