Installing A Water Meter; Installing/Replacing The Filter Cartridge; Purge With A Flushing Valve; Purge With The Appliance - BWT Bestmax SMART Instrucciones De Montaje

5.5 Installing a water meter

BWT recommends the installation of a water meter in the inlet of the filter cartridge in case the filter
system is used for a device without an integrated water meter (e.g. coffee machine) which indicates
the required replacement of the filter cartridge. With the water meter the filter cartridge's residual
capacity can be determined at any time. BWT recommends installing the BWT Aquameter. Observe
the operating instructions of the BWT Aquameter.

5.6 Installing/replacing the filter cartridge

I CAUTION!
The filter cartridge may only be installed in a genuine BWT water+more filter head.
f
Work cleanly, avoid impurities on the filter system.
f
Close the check/shut off valve before exchanging the filter cartridge.
f
Unpack the filter cartridge and remove the hygienic cap.
Before installing the filter cartridge mark the installation and replacement date (no later than
7
12 months) on the product label of the filter cartridge. Optionally, a service pass can be obtained.
Fill in the dates and fix the service pass to the filter head e.g. with a cable tie.
Ensure connecting threads are not „crossed". This avoids twisting the rubber seals.
In case of replacement unscrew the filter cartridge clockwise out of the filter head.
8
Screw the filter cartridge counter clockwise into the filter head.
Open the check/shut off valve and check the system for leaks.
During commissioning, the filter has to be purged/flushed (Section 5.6.1 and 5.6.2). The minimum
flushing volume is given in Section 2.2.

5.6.1 Purge with a flushing valve

A flushing valve is included in the filter head besthead FLEX. For the filter heads BWT besthead ST/
9
PA, BWT recommends installing a flushing valve/purging tap after the filter system. Flushing/purging
can simply be done with this tap. Observe the operating instructions for the flushing valve.

5.6.2 Purge with the appliance

If the downstream appliance (e.g. coffee machine) has a function for commissioning filter cartridges,
the filter system can be purged from the appliance. Observe the appliance's operating instructions.
NOTE!

Do not feed the boiler of the appliance with the purging water.
