5.6 Installing/replacing the filter cartridge

I
CAUTION!
f The filter cartridge may only be installed in a genuine BWT filter head.
f Work cleanly, avoid impurities on the filter system.
f Close the check/shut off valve before exchanging the filter cartridge.
Unpack the filter cartridge and remove the hygienic cap.
Before installing the filter cartridge mark the installation and replacement date (no later than
6 months) on the type label of the filter cartridge.
In case of replacement unscrew the filter cartridge clockwise out of the filter head.
Screw the new filter cartridge counter clockwise into the filter head.
Open the check/shut off valve and check the system for leaks.

NOTE!
f During commissioning, the filter has to be purged/flushed.
f To avoid airlocks during initial installation, turn the cartridge upside down and flush the required volume through the flush valve. Whilst
flushing, press and release the button every 15 seconds for 2-3 seconds each time. This will agitate the resin and help remove any
trapped air bubbles.
f For the best results, occasionally turn the cartridge upside down whilst it is in use. This will remove any accumulated gases that may be
trapped within the resin. After a few seconds, return the cartridge to the normal upright position.
f The minimal flushing volume is given in Section 2.2. The volume of purge water is to be dismissed.
