POLYPHOSPHATE DISPENSER INSTALLATION
Disconnect the boiler and disassemble the casing.
Partially empty the water contained in the cylinder by acting
on the drain valve (6).
Before performing this operation, close the boiler cold water
inlet valve and open any domestic hot water valve of the system
in order to allow the inlet of air into the cylinder.
Disassemble the cold water inlet pipe (5) on the boiler, connected
to the mixing valve and to the cylinder.
In its place, mount the kit components as shown in the figure,
making sure you insert the flat gaskets between the various joints.

dispenser unit (3).
At this point connect the dispenser unit (3) to the cold water
inlet pipe.
Once assembly is complete, the ring nut and the polyphosphate
dispenser (3) must be accessible from the right hand side door,
in order to refill with Cillit-55 IG. Make sure you have closed the
cylinder drain valve (6) and close the domestic hot water system
valve which was opened previously. Reopen the domestic cold
water inlet which was closed previously.
Re-mount the boiler casing.
