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

6.5.2 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.

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.

Determining filter capacity and setting the bypass

The bypass setting and the filter capacity are based on the carbonate hardness of the
drinking water and the usage of the filter cartridge.
Procedure:
1. The carbonate hardness can be requested from the water supplier
or established by means of a quick test (droplet test, Fig. 7). The
bypass setting can be selected based on the carbonate hardness
and its application. The typical filter capacities are shown
in Table 1–3 in Section 10.
