4.2.3 Cleaning or replacing the fi lter cartridge
•
When the pressure gauge needle is close to the "DIRTY" arrow, the fi lter cartridge should be cleaned.
The "DIRTY" arrow positi on indicates that the pressure in the fi lter has increased in relati on to its initi al operati ng
pressure and that the fi lter cartridge is dirty.
•
Change the fi lter (see para. "4.2.2 Drain the fi lter").
•
Remove the fi lter cover by pressing the locking tab on the fi lter body and unscrewing the clamp ring in an anti -
clockwise directi on.
•
Remove the fi lter cartridge by pulling it upwards.
•
Clean the fi lter cartridge with a hose pipe (do not use a high pressure jet), directi ng the water jet inside and then
rinsing the outside. Use a soft brush, if necessary.
•
To clean off algae, sun tanning oils and lime scale, soak the fi lter cartridge in a degreasing solvent and then in a de-
scaler. Ask your retailer for the appropriate products.
•
Once the cartridge is clean, replace it in the fi lter body or insert a new cartridge, if necessary.
•
Push the fi lter cartridge fi rmly into its housing and ensure that the bleed pipe is properly located inside it (see para.
"4.2.3 Cleaning or replacing the fi lter cartridge").
•
Check the conditi on of the seal (on the clamp ring inside the cover). Replace it if it is damaged. If necessary, apply a
silicone based lubricant to facilitate installati on.
•
Switch on the fi lter (see para. "3.2 I Operati on").
Tip: cleaning the fi lter cartridge
•
It is easier to clean a fi lter cartridge when it is dry. Simply tap it to remove most of the dirt. It can then
be cleaned with water. In such a case, it may be worthwhile having a second cartridge, so that they can
be alternated.
