5 Installing the filter system

NOTE!

Decarbonised water contains free carbonic acid. Only appropriate materials are to be used for
f
installation. Original BWT accessories are recommended.

5.1 Unpacking the filter system

Remove the filter system from the packaging. Inspect the delivery for completeness and transport
damage. Defective parts must be replaced immediately.
I CAUTION!
Faulty or defective parts must be replaced immediately.
f
Always ensure a safe and clean working environment.

5.2 Fitting the filter bracket

I CAUTION!
Read "Technical data" (page 10) and "Operating/Safety instructions" (page 11) prior to
f
installation.
To connect the filter system to the appliances only use hoses according to DVGW W 543 or
f
NSF 42/53.
When installing accessories (hoses, connection sets), observe the installation dimensions and
f
bending radii.
To install the filter system, choose a location that enables simple connection to the water mains.
The wall bracket has to be aligned and mounted to allow a convenient access and replacement of
the cartridge.
The filter system must be securely bolted to a wall using the filter bracket.
The filter system can be operated in a vertical or horizontal position.
For easy service and replacement of the filter cartridge after installation a minimum clearance/
2
distance of 65 mm (2.56 inches) is required at the bottom of the cartridge.
When installing the filter cartridge for horizontal operation, ensure that it is resting on the floor. The
distance G between the bracket and the floor for horizontal installation is given in Section 2.1.

5.3 Determining filter capacity and bypass setting

The carbonate hardness can be requested from the water supplier or determined with a titration test.
4 The bypass setting can be selected based on the carbonate hardness and its application. The typical
filter capacities are shown in Table T1, T2, T3 or T4 (page 113 onwards).
There are four setting options for the bypass. The default bypass setting is "2". The bypass can be
5
set by pressing the button "a" and twisting the cap on the filter head clockwise or counter clock wise
until the required bypass setting is reached and the cap snaps into place.
The bypass should be sealed with the included warranty label. Note month and year on the label.
NOTE!

BWT recommends to choose the size of the filter cartridge with its capacity to be due for
f
replacement in 6 to 12 month intervals.

5.4 Fitting the filter head

I CAUTION!
The filter head is never to be left under mains water pressure without a fitted filter cartridge.
f
The tightening torque of the fittings (inlet/outlet) must not exceed 15 Nm!
f
NOTE!

The integrated Aquastop in the filter head prevents a water flow without mounted filter cartridge.
f
6
Insert the filter head into the filter bracket, observe the correct direction of flow.
Mount hoses (observe the bending radii!) for the water intake and outlet at the filter head.
Connect the water intake hose to the existing check/shut off valve in the intake.
Connect the water outlet hose to the appliance.
