Exchanging the phosphate
cartridge
The phosphate cartridge must be
exchanged after 12 months at the latest!
The phosphate cartridge is exchanged
as follows:
1. Close the shut-off valves (1) upstream
and downstream of the device (see Fig. 5).
2. Open the discharge valve (2) contraclock-
wisely so that the pressure remaining in the
device can escape (see Fig. 6).
3. Unscrew the union nut (3) at the phos-
phate cartridge contraclockwisely.
4. Lift the empty phosphate cartridge (4) out
of the device (see Fig. 7).
5. Insert the new phosphate cartridge (5)
into the device.
6. Screw in the union nut (3) clockwisely and
tighten it hand-tight (approx. 1 Nm) (see Fig. 8).
7. Close the discharge valve (2) clockwisely
all the way to the stop.
8. Open the shut-off valves (1) again.
9. De-aerate the device. At an extraction
point let out water for about 1 minute with a
flow rate of approx. 1000 - 2000 l/h (resp.
4,4 - 8,8 gal/min).
