6.5.2 Mounting the Filter Head

I
CAUTION!
f Make sure that the filter head is never left under system pressure without any filter cartridge
f The tightening torque of the fittings (inlet/outlet) must not exceed 15Nm!

NOTE!
f The integrated shut-off in the filter head prevents a water flow without the filter cartridge
f Before removing the filter cartridge the separately installed shut off valve on the filter system inlet
should be closed (not included in the scope of delivery).
Procedure:
1. Insert the filter head on the wall bracket
2. pay close attention to the correct direction arrow on the filter
head, filter is only to be installed in the directional flow.(see Fig.5)
3. mount and connect the adapters/hoses to the filter head
(consider the bending radius of the hoses) (see Fig.6)
4. connect the inlet to the water supplies inlet/shut-off valve
(shut-off valve not part of the scope of delivery)
5. connect the outlet of the filter system to the
consumer system/device
6. open the inlet valve and check if the system is leak-proof
7. close the inlet valve
6.6

Installing a Water Meter

VIZION recommends the installation of a water meter at 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 actual/remaining capacity of the filter cartridge can be displayed or
calculated at any time.
Procedure:
1. Read the Instruction manual of the water meter
2. Mount the water meter on the filter head (outlet) by considering the flow direction.
Display should be visible. Programming and start up of the water meter according to the
instruction manual provided.
3. Connect all the hoses at the inlet and outlet of the water meter
4. Open the inlet (shut-off valve)
5. Check the installation for leaks

Determination of the Filter Capacity and the Blend Setting

The blend setting and the filter capacity are based on the carbonate hardness of the drinking water
and the application field of the filter cartridge.
Procedure:
1. The information of carbonate hardness of your drinking water can
either be provided by your water supplier or can be determined by
an analyses (e.g. droplet test, Fig.7)
Based on the determined hardness and application, the blend
setting can be determined according Table 1-4 chapter 8 and the
filter capacity is given in the tables as well.
