Deionization and Polishing module installation
.
3.6.1. Push the stems in the
¼’’ elbows with ¼’’ tubes into the John Guest fittings of the
Deionization and Polishing modules.
3.6.2. Install the deionization and polishing modules. The positions of the modules are
marked with labels “IonPro deionization module” and “Polishing module”. Each
module has now John Guest elbows and short tubes installed. Open the front door.
Place a module at the labelled site; push the tubes into John Guest fittings at the
inner wall. Then attach the module fully to the inner wall by putting the latch at the
bottom of the module into slot on the wall.
3.6.3. Screw the pre-filters into the grey filter heads.
4. Rinsing the system
Note
:
The pre-filter should be rinsed prior operation and each time new
filter is installed. Failure to do so can lead to reduced life of the
reverse osmosis membrane.
Rinse the system according to the following procedure:
4.1.
Open the front door. Disconnect the pre-filter outlet tube (right behind the prefilter
heads) from the John Guest fitting (see pictures below). Put a beaker under the
tube.
4.2.
Switch on the unit. The display is switched on and “STANDBY” message is shown.
4.3.
Open the tap water supply.
4.4.
Press and hold the
Run
key (Fig. 4/8) for 2 seconds and collect approximately 1
litre of water and press the
Run
key to stop the water flow. The pre-filter is rinsed.
Note
:
If “TnkFull” message is shown then probably the tank plug is not
connected.
