4. Installation

washer and fixing nut supplied.

5. Install the tap as described from point 3 onwards of ‘Installing the tap’.
6. If the drain bend is facing the wrong way, slacken off the fastening nut above the

bend, turn it to the correct position and then tighten up the fastening nut again.

7. Connect the drain bend to a siphon connecting sleeve, using a 22 mm diameter

hose. If no siphon connecting sleeve is available, use the snap connecting sleeve.
a. Place the snap connecting sleeve on the side of the siphon facing the sink. Drill a

13 mm diameter hole in the drain pipe behind the snap connecting sleeve for a
drain connection. Use a suitable sealant to make a watertight seal between the
snap connecting sleeve and the drain pipe.

Optional: Installing an external ion exchanger

An external ion exchanger can be used to prevent limescale deposits in the hot water
tank of the undersink unit and thus extend the maintenance intervals.

Note: If installing an external ion exchanger, follow the instructions supplied for
the filter head and filter cartridge.
Note: to flush through the ion exchanger before using it for the first time, connect
it directly to the angle valve and drain the water into a bucket or drain.

1. Remove the bridge between the ‘to accessory’ and ‘from accessory’ connections on

the undersink unit.

2. Connect the inlet on the filter head of the external filter to the ‘to accessory’

connection using a flexible hose and ⅜“ union nuts.

3. Connect the outlet on the filter head of the external filter to the ‘from accessory’

connection using a flexible hose and ⅜“ union nuts.

4. Set the bypass valve on the rear of the unit to position ‘B’, using a suitable

screwdriver or a coin. After that, the water to be heated will flow through the
external ion exchanger instead of flowing through the internal filter. The cold water
will still be filtered through the internal filter.

Commissioning

1. Before using the unit for the first time, flush through the connecting pipes and hoses

thoroughly. To flush, detach the flexible hose from the water inlet of the undersink
unit and hold it over a drain or bucket. Turn on the water and allow it to run for
several minutes. Then reattach the hose to the water inlet of the undersink unit and
check the installation for leaks.

2. Set a pressure of 3.0 bar on the pressure reducer of the carbon dioxide gas bottle.

Turn the adjusting screw anticlockwise to reduce the pressure. Turn it clockwise to
increase the pressure.

3. Check the gas-carrying connections for leaks. Caution - gas released can be very

cold. Use a leak detecting spray or soapy water so that even minor leaks will be
detected.

4. If no leaks are found, plug the plug into the socket and press the On switch on the

right-hand side of the undersink unit to activate the unit.

5. A prompt will appear on the display asking you to flush the carbonizer with carbon

dioxide.
a. Touch ‘Start’ to start flushing. Carbon dioxide will then flow through the unit and

can be heard at the tap.

b. After about 10 seconds touch ‘Stop’ to stop flushing and then press ‘Next’ to

continue with commissioning.
