4.4.6

Flushing the pre-filter

The WTC 600 LP/MP pre-filter must be flushed if the differential pressure of the pre-filter
immediately after back-washing is more than 0.5 bar.

Before flushing the filter, check the manometer for correct display values and
exchange if necessary!

Pre-filter blockages are caused above all by changed water constituents.
A renewed water analysis must be carried out in order to remove the cause of
blockages. Notify sales department! Additional treatment stages possibly required!

- Composition of the pre-filter flushing service kit

Auxiliaries:

- Flushing tank

- Four connection hoses

- Conductivity measuring device for comparative measurement after flushing

- (Goggles, gloves, apron)

- Flushing pump

Initial situation:

- RO system set to switched off operating mode and with master switch switched on.

Work steps:

1.

Add 30 litres drinking water to the flushing tank and add 2.2 litres RM Kleen MCT 103

2.

Dismantle the back-washing hoses at the pre-filters, connect the service kit hoses and feed
to the flushing tank

3.

Connect the flushing pump to the pre-filter untreated water inlet

4.

Start back-washing

5.

Switch on flushing pump

6.

Leave the flushing solution to circulate until the back-washing is finished (approx. 10 min)

7.

Leave the flushing solution to stand for 30 minutes

8.

Repeat the procedure from item 4 once again

9.

Reinstate the original piping and carry out a complete backwash.

If this cleaning is unsuccessful, the media filter must be disinfected. The service kit contents and
the flushing sequence is the same as for flushing the pre-filter, however the chemicals used are
those given in table 26.
