6. Mark the date (month/year) of installation on the installation plate
supplied and glue it to the filter head (see Fig. 5).

6.4.2 Fitting the filter head

I
CAUTION!
f Under no circumstances may the filter head be under mains water pressure for a prolonged
period without a filter cartridge screwed on.
f The torque of the fittings must not exceed 15 Nm!

INFORMATION!
f Mounted in the filter head is an Aquastop that prevents water
from escaping if the check valve is open and no filter cartridge
is installed.
f The existing check valve must be closed before the filter cartridge
is removed.
Procedure:
1. Insert the filter head into the filter bracket.
2. Observe the correct direction of flow (see Fig. 6).
3. Mount hoses (observe the bending radii!) for the water intake and
outlet at the filter head.
4. Connect the water intake hose to the existing check valve in the
intake.
5. Connect the water outlet hose to the appliance.
6. Open the check valve and check the system for leaks.
7. Close the check valve.
6.5

Fitting a water meter

BWT recommends installing a water meter in the filter cartridge intake if the appliance, e.g. coffee
machine, does not have a meter which displays when a filter cartridge requires replacing. If a water
meter is installed, the filter cartridge's residual capacity can be determined at any time.
Procedure:
1. Read through the operating instructions for the water meter.
2. Fit the water meter to the filter head. Observe the direction of flow! Fit the display in the field of
vision. Program the water meter in line with the operating instructions and start it up.
3. Fit the water outlet hose to the water meter outlet.
4. Connect the water outlet hose to the appliance.
5. Open the check valve.
6. Check installation for leaks.
6.6

Installing the filter cartridge

I
CAUTION!
f The bestcare filter cartridge may only be installed in a genuine BWT filter head.
f Work cleanly, avoid impurities on the filter system.
Procedure:
1. Take the filter cartridge from the packaging film and remove the
hygiene cap.
2. Before installing the filter cartridge, mark the installation date and
the replacement date (no later than 6 months) on the filter's rating
plate (see Fig. 9) or fill out the Service Pass that can be optionally
Fig. 5 obtained (see Fig. 10) and fix to the filter head using the cable tie.
3. Turn the filter anticlockwise in the filter head (see Fig. 11).
4. Open the check valve.
5. During commissioning, the filter must be flushed and bled (see
Sections 6.6.1 to 6.6.3).
The minimum flushing volumes are stated in the table below.
Table: Minimum flushing volumes
bestcare Type
Flushing volume in litres

INFORMATION!
After a break in operation exceeding two days, the filter system must be flushed with
Fig. 6 a minimum of 4–5 litres of water.

6.6.1 Flushing/bleeding via the appliance

If the downstream appliance (e.g. water dispensers) has a function for commissioning filter
cartridges, the filter system can be bled/flushed from the appliance. Observe the operating
instructions for the appliance.

INFORMATION!
Please do not route the water direct to the boiler when flushing the filter cartridge.

6.6.2 Flushing/bleeding via a flushing valve

BWT recommends that a flushing valve is fitted at the filter cartridge outlet. If a flushing valve
is installed in the filter system outlet, the filter can easily be bled and flushed via this flushing
valve. Observe the operating instructions for the flushing valve.

6.6.3 Flushing/bleeding via the water outlet hose

If flushing/bleeding is not possible using one of the methods mentioned above, the filter
system can also be bled via the water outlet hose.
Procedure:
1. Close the check valve.
2. Disconnect the water outlet hose from the appliance, e.g. coffee
machine.
3. Attach the end of the hose to the 10 litre container below.
4. Open the check valve.
5. Flush/bleed the filter system until bubble-free and clear filtered water
emerges (for flushing water volume, see the recommendations in
Section 6.6).
6. Close the check valve.
7. Refit the water outlet hose onto the appliance.
8. Open the check valve.
9. Check the filter system and all connections for leaks.
